1494b094c7 port: record H3 -- the PRESS (A) plate arrives late, and which half is ours
Human play-test, 2026-09-01. Three candidate causes and they do not share an
owner: the unit->seconds constant is the Decoder's, the clock origin and rest.t
are ours. REFUTED.md records that believing rest.t already put a plate 3.97 s
late once. Establish which half before asking.

72f116a3b4 port: Ⓐ was never bound to the pad, and the stick is not an edge
Both found by a human playing the port on a real controller. Both were
invisible to every check this port has, for one reason:

  `--script` sends InputEventAction, which BYPASSES the input map.

So the harness asserted every line of code AFTER the map and nothing about the
map itself. Measured on this Godot, not remembered -- the remembered answer was
wrong:

  ui_accept   key:Enter, key:Kp Enter, key:Space     <- no joypad at all
  ui_cancel   key:Escape                             <- no joypad at all
  ui_up       key:Up, JOYBTN:11, JOYAXIS:1-          <- d-pad AND left stick
  ui_down     key:Down, JOYBTN:12, JOYAXIS:1+

Four actions worked on the pad and two did not, which presents as a broken
controller: navigation moved, Ⓐ skipped nothing and opened nothing. Godot
4.7.2 binds no joypad button to ui_accept or ui_cancel.

Gamepad.bind_missing() ADDS the two buttons to the built-in actions rather than
redefining them in project.godot, which would replace the built-ins wholesale
and drop the keyboard bindings silently.

Second defect, same blind spot: an InputEventAction is not an analog axis. The
left stick is bound to axis 1, and an axis is not an edge -- held at deflection
it emits an event per jitter, each reporting the action pressed. That was one
cursor step per jitter ("moves the cursor too fast"). The stick is now latched
to one step per deflection, with hysteresis so a stick resting near the
threshold does not chatter.

AUTHORED, and deliberately the conservative half: whether the game REPEATS a
held direction, and how fast, is an oracle question. One deflection one step
cannot run away and invents no rate. Logged as BLOCKED H1.

tools/port/verify-input asserts the map and the latch, with a control that
removes each check's OWN subject -- its first version inverted all nine
assertions when only two depended on the fixup, and reported seven correct
checks as broken. Three rows say plainly they are not controllable (they assert
Godot's own bindings) and one is a negative carrying a positive control (R4),
rather than faking an inversion for either.

Also logged BLOCKED H2, unguessed: the splash blur/fade-in is more pronounced
in the game than in the port. The port applies no blur at all. Noted there that
the two splashes are the only screens reaching the rest() plateau-less
fallback, which the R1 pass just re-opened in both directions.

0f1b11920c retro: tick §7.1 -- the R1 register reclassification is done, and what it found
Done 2026-09-01 by the human on the Decoder's tip (branch
human/r1-register-reclassification): all 222 REFUTED.md entries carry an
⟨instrument⟩, ten moved  -> 🟡, R1 is standing text in PROTOCOL.md, and
tools/stale-instrument is the --stale query.

Flagged here because one of the ten is load-bearing for the port: rest()
decides the pose every plateau-less element is drawn at, and the question is
open in BOTH directions -- each leg runs through our renderer.

3e9160b372 port: confirm the plate quad by size, and record a frame-spacing discrepancy I cannot close
Read the Decoder's existing title draw log from the ref. The additive quad carries
per-vertex alpha 68, 67, 56 across log frames 1, 2 and 4.

Identification confirmed independently and without using their attribution: the
quad is 537.6 x 75.6 px and ptbtn00f.png ships at 537 x 76.

Their free check on my ramp holds -- all three alphas are at or below my declared
peak of 80 and none equals a keyframe value, so the game interpolates rather than
steps. Two independent decodes agreeing.

The frame spacing does not fit. At HANDOFF Q1's 2 units per rendered frame my
falling segment predicts 68, 64.5, 57.6 against observed 68, 67, 56; at 0.5 units
it predicts 68, 67.2, 65.4. No constant rate fits both steps.

Three candidates I cannot separate: my ramp is wrong somewhere, the log's frame
numbering is captured rather than engine frames -- it skips from 2 to 4, so it is
demonstrably not dense -- or emulator pacing varies. The middle is most likely and
cheapest to check, and it is theirs.

It does not disturb the ramp's shape or ceiling, which the alphas confirm. It
disturbs only posing my renderer at their captured instant by stepping units, so
the vertex alpha stays the right readout and a frame index would have been wrong.

dfb768270a port: pre-register the plate composite test, and catch my own prediction being wrong
The Decoder's R2 note: alpha peaks at 80 of 255, so the composite difference is a
small signal either way and the expected magnitude should be set before the test.
Committed here before any capture exists.

Rendering the same pose at peak alpha under both composites: 25 015 px footprint,
mean |additive - alpha-over| 16.92 levels inside it, max 50, RMS over the whole
frame 3.746.

My first prediction was wrong and that is the useful part. The composites differ by
exactly alpha*bg, which with mean background 94.78 predicts 29.73 levels. Measured
16.92. The formula uses the keyframe alpha and ignores that the sprite carries its
own per-pixel alpha channel modulating it -- implied mean sprite alpha about
145/255. Caught only because the prediction was written down and disagreed with the
render.

The pre-registered test: additive is brighter than alpha-over at every footprint
pixel in one direction, so the discriminator is regional SIGN over 25 015 pixels,
not per-pixel magnitude. If the game is additive, rendering alpha-over must leave
the footprint about 17 levels darker than the capture relative to the surrounding
frame, and additive must leave no such regional bias. Neither bias refutes both and
points at the ramp or the pose instead.

Feasibility stated before asking for a run: as a whole-frame RMSE the difference is
3.746, below the title's own +/-5.56 capture-phase term, so verify-capture's
headline number could not settle this even at peak alpha. It is discriminable only
as a signed regional statistic.

4a2f96167f port: the plate's ramp was already in my export, and the renderer reproduces it
The Decoder is paused and could not take the capture I asked for, and said the disc
half might not need them. It did not, and it did not need a new decode either: the
ramp is already in export/screens/title/press_start.json. ptbtn00f carries eight
keyframes on a 120-unit loop, alpha in the high byte of fade_argb, 0 -> 80 -> 0
with the peak held across t=35..50.

Two things follow with no oracle. The blind phase is confirmed from the disc rather
than inferred from rendering: alpha is exactly 0 at phase 0. And the renderer
applies the ramp faithfully -- rendered contribution against declared alpha across
six phases gives r = +0.9982, slope 0.4036 levels per alpha unit.

So when and how strongly the port draws the highlight is verified. Only the
composite is open, and the existing capture cannot settle it under either reading
of the clock: posed at t=237 the phase is 117 where alpha is about 0, and the
harness independently pins loop-phase 0 where alpha is exactly 0. Both agree, which
is worth stating because I did not have to assume which clock the record runs on.

The ask therefore narrows from "a mid-pulse instant" to a named window: one capture
anywhere in t mod 120 in [35, 50], where alpha holds at its peak of 80.

9ff5c5f082 port: draw the plate's highlight additive, and find my harness poses it where it cannot be seen
blend-bit-vs-oracle.txt entry 2: ptbtn00 alpha-over, ptbtn00f ADDITIVE -- the
PRESS (A) plate and its own highlight, one bit apart. Entry 4, the whole title, is
alpha-over throughout including ptlogo_back2/ptlogo_back2eff, which independently
kills the "frame-shaped and mostly transparent means additive" rule I declined to
adopt.

Bands are now per DRAW OP rather than per paint-order entry: one band per element
cannot express base alpha-over with its own focus record additive.

The change reported zero three times and each zero had a different cause.

First, additive_elements was assigned to `view` in three places and to `overlay` in
none, and the plate is an overlay -- every other decoded rule on that page goes to
both.

Second, I then measured that the element is never drawn, suppressing its sprite at
six times across the cycle for 0 px every time, and was one commit from filing "the
port never draws the plate highlight" as a defect. That sweep was invalid: I varied
--time while passing --loop-phase=0 in every run, and --loop-phase pins exactly the
clock a looping record runs on. Six samples of one phase.

Third, swept properly, ptbtn00f contributes 0 px at phase 0 and 22-29k px at phases
20-100 -- and verify-capture's title_plate row poses at loop-phase 0. The row that
validates the plate is blind to the plate's pulse by construction. It correctly
reports 13.03 / 0.09 % unchanged while the fix moves 26 319 px at phase 20. Stated
in the tool next to the pose.

Not verified against the oracle: every title-plate capture we hold is at the blind
phase, so no capture here can confirm the port now draws it right. Asked.

1b8f9d2813 port: fix the runbook's unattended walk -- it never reached the submenu P5 rests on
RUNNING.md gave `--script=down,down,accept,cancel` as the unattended P5 walk. Two
downs from the opening item lands on TUTORIAL, whose destination this export does
not carry, so the example printed a not-carried message and returned to the title
without opening a submenu at all. EXTRAS is the fifth item and needs four.

The one submenu the milestone's gate rests on was the one the runbook's own command
did not reach, and it survived because the command completed successfully. Third
instance this session of "the run succeeded and the answer was wrong", after the
MIX-default material and the vertex dump that captured two of six quads -- and the
first one sitting in the document written for a human to follow.

Verified by running both paths. Also verified end to end this iteration, on the
real binary rather than from the document: cold boot reaches the title in 152.9 s
with the intro playing 142.2 s for 137.4 s of media (+3.5 %); wrap, the left/right
no-ops, EXTRAS opening on MISSION SELECT, B restoring the item you left, EXTRAS
resetting to its own first item on re-entry, and the focus surviving a title round
trip all behave as the table says.

2af316dd82 retro: the agreed result, plus the cue-suppression matrix it came out of
Agreed retro with the Decoder at docs/agents/RETRO-2026-08-31-agreed.md; their own
review is at docs/agents/RETRO-2026-08-31.md on auto/frame-blend-draw-path.

Twelve rules, of which the ones neither of us had: a refutation whose instrument is
one of our renderers is not a refutation but "our renderer disagrees" (this cost
weeks, both ways); a negative must carry a positive control, which no "undecodable
with reach" page either of us has written ever did; and a disagreement is evidence
about the chain disc -> decode -> render -> capture, not about the link being
looked at.

The gap underneath our controls, stated: they verified capability, not
configuration. My additive material passed every control because they tested
whether the method detects a blend difference, not whether this run had blend_mode
set -- it was Godot's default MIX. Their vertex dump passed every control because
they tested the NDC conversion, not whether it captured all six quads.

Nothing applied to PROTOCOL.md. The register re-classification changes the file
both agents read to decide what not to try, and two agents agreeing is not the
right authority for that.

Also committing the work that was pending when the stop came: verify-menu-audio
now settles cue presence by suppression -- silence one cue's .ogg, re-record the
same walk, and require its own correlation to collapse. All three cues sound
(+0.158 / +0.637 / +0.526). The bed-only margin no longer renders a verdict: it
called `move` NOT FOUND on three runs at 0.109-0.131 while the cue was
demonstrably sounding, and across runs the same cue reads 0.131 and 0.158, so the
threshold was never a property of the cue.

The off-diagonal is reported as masking rather than asserted: silencing confirm
raises back by 0.468 because the game plays them 90 ms apart under a 0.15 s
template. An assertion there would fail forever on correct audio.

d0163a64fa port: take the completed EXTRAS blend set, and record two refutations that land on me
EXTRAS whole-screen residual 1.97 -> 0.63; ptframe4 31.90 -> 1.14, pteff21/22/23
from 12-14 to under 0.8. The four elements I reported as in no draw were in a draw
all along -- the vertex dump was capped at two quads and the batch holds six, so
four were dropped with a well-formed line and no ellipsis. Same failure class as my
MIX-default material: the run completed, the output parsed, the answer was wrong.

Their pteff10 flag, tested by holding it alpha-over with everything else additive:
tone-corrected residual 0.630 additive against 1.704 alpha-over, but raw RMSE 12.91
against 9.98. They disagree because the port already renders +8.50 levels brighter
than the capture on this screen before any of this, so raw RMSE punishes added
light whether or not the light is right. Adopted on the measurement plus the
structural metric; extras raw-rmse went 11.43 -> 12.88 and that is stated, not
hidden. The differing region halved, 0.07 % -> 0.03 %.

Refuted, mine: "every decoration 0x0 and every button 0x3002" was a two-screen
generalisation I called a confirmation, one message after objecting to exactly that
move in their page. My own export held the counter-examples -- ptbtn00 is 0x73002
and my exporter calls it unknown rather than button; three title elements are
0x3000, button-shaped and not focusable. kind & 0x2 is the focusable flag.

Refuted, mine: the sweeps DO run on the main menu. Their log retains NDC and both
strips overlap the screen in every captured frame, stepping in opposite directions
with vertex alpha ramping. My phase sweep measured that the PORT'S sweeps make the
match worse, which is a statement about my rendering, not about the game. A
best-match argument for an absence cannot separate "not there" from "there and
drawn wrong", and I had that caveat written down and read past it.

Not flipped: the strips are additive with a ramping vertex alpha and the port has
neither on the leaf path, so enabling the loop today would be more correct in
behaviour and worse on screen. The ramp is asked for. What changed today is the
claim -- the port is wrong here and now says so.

3a3f5bae85 port: free the canvas items I leaked, and refute the blend measurement's reach sentence
The RenderingServer rewrite leaked 5 CanvasItem RIDs per run -- exactly the number
of paint-order runs on the main menu. Items created through the server are not
owned by the node; a child Node2D would have been collected for me, and the reason
for not using one is the reason this had to be paid for. Freed in _exit_tree.

Nothing failed. verify-capture was green on every screen and the pictures were
right; the leak line sat next to "N ObjectDB instances were leaked at exit", which
BLOCKED.md records as engine-side and not ours after releasing every reference the
port owns moved the count not at all. A new leak line beside a known-benign one is
close to perfect camouflage. What distinguished it was the number: 5 is a count of
my bands.

Refutation, and it lands. ui-blend-mode-measured.md closes "every element on the
two screens the port ships is in the table except the two above and pteff10".
Checked against my export, counting the summary table's prose rows as coverage:
exactly right for main_menu, and on EXTRAS it misses four -- ptframe4, pteff21,
pteff22, pteff23. Five, not one.

They are not an arbitrary four. They are precisely the elements the port now
measures as the worst on that screen, ptframe4 at 16.19x the frame mean. Every
measured row still stands and the port has transcribed all of them; what is wrong
is the reach, and it is the difference between "one loose end" and the open ask in
BLOCKED.md, which now says so.

Secondary, offered as such: "every button" in the summary row is a class
generalisation in a document that warns its reader to take the table as per-element
facts. No button appears in the EXTRAS draw log at all. Very likely right, nothing
of mine depends on it.

271c49d21f port: transcribe the sweeps' additive blend, and re-run my own menu-looping evidence with it
ui-blend-mode-measured.md names both rotated sweep strips additive in the same row
as the frames. Those are ptloop01/ptloop02 here, now in additive_elements for both
measured screens. It changes nothing visible: on the menus the port runs the leaf
group once and parks it off-screen, and suppressing both sprites at leaf-time 100,
200 and 300 changes 0 pixels each time. It is in the file because it is measured.

Refutation attempt on their identification, and it survives with a number of mine.
The automatic matcher reports "no match" for those two draws; they rest on one
control reproducing heights 1134 and 1303. Rendering the menu at a phase where the
sweeps are on screen and suppressing them gives a footprint 884 px wide against
their 889.6 -- 0.6 % apart, derived without using their number. The heights differ
as they should: my bbox is clipped by the screen, theirs is the full quad extent.

The blend was a confound in my own earlier evidence. loop_leaf_why scoped looping
to the title partly on a phase sweep of mine that drew the sweeps ALPHA-OVER, so
an on-screen sweep was composited wrongly and then scored against the capture. Re-
run with additive and looping enabled for the menu, through a scratch export root
so the repo was untouched: parked 0.0208 %, phase 150 on-screen 0.0851 % with the
sweeps painting 58 027 px, other on-screen phases 0.086-0.122 %.

The conclusion held and got stronger -- 3x with the wrong blend, 4-6x with the
right one -- so the scoping stays and the correction is what is recorded. Still one
capture, and best-match is still weak evidence for an absence.

And a reading of the new log that I did not make: it shows both sweeps SUBMITTED
on the main menu in every frame group, which is not evidence they animate there. A
quad parked off-screen at x=1521 is still a draw call. The log settles the blend
and not the visibility, and both questions arrived in the same artefact.

7fef6d0678 port: draw the measured additive blend -- main_menu 13.21 -> 10.67
The Decoder logged RB_BLENDCONTROL0 per draw in Canary on both screens.
0x01010101 is src=ONE dst=ONE, additive. That makes the blend a transcription
rather than my proposal, and they withdrew the "any blend you choose is authored"
instruction explicitly.

Their control is what licenses the change: one pixel shader, 0xE59B2B3DA4AA9008,
runs with BOTH blend states on the main menu -- 12 additive draws and 18
alpha-over. The frames and ptbase share a shader; only the blend register differs.

authored/rendering.json gains additive_elements per screen. Every id is a measured
draw and the reach is written beside it.

verify-capture: main_menu 13.21 -> 10.67 (0.06 % -> 0.02 %), extras 13.38 ->
11.43, main menu with ptbtn04 focused 13.82 -> 11.36. Per element, ptframe1
22.72 -> 4.17 and ptframe2 13.09 -> 3.32.

Neutrality control, free with the table: publisher_logo 2.17 and developer_logos
3.05 are unchanged to the digit. Those are the screens whose metric is absolute
and they carry no additive element, so the rewrite that routed every draw through
RenderingServer canvas items did not change the picture. The improvement is the
blend, not the plumbing.

RenderingServer rather than child Node2Ds because boot.gd calls view.queue_redraw()
from nine places and none reaches a child node -- bands would paint the previous
pose, which under --script=wait is a plausible wrong capture rather than an error.
Runs are recomputed per frame: the additive elements are consecutive on both
measured screens, and that is an accident of those two screens.

And the change first ran with the material left at its default MIX, moving
ptframe1 from 22.72 to 22.69. Nothing errored and a 0.03 move is a plausible
negative result. It was caught only because the measurement predicted a large move.

Not done: ptframe4 is now the worst element on EXTRAS at 16.19x the frame mean and
additive would plainly help it. It is not in the measured table, so it is not in
the file. Filed in BLOCKED.md with pteff21/22/23, which are also in no captured
draw.

Refuted, mine: "neither frame has a fully-opaque pixel" was true and was not the
discriminator -- pteff10 has max alpha 130, no opaque pixel, and measures nearly
exact. The direction survived; the reason for it did not.

ee47b47440 port: discriminate the blend -- additive halves alpha-over's error on both frames
Last iteration could say the shortfall scales with the background but not which
curve. That is decidable with no RE: an element rendered over two different
backgrounds gives two equations in a and aC, and the mod tree supplies the second
background by suppressing pteff10/pteff12, which moves it by a mean of 26 levels.
No placement, no coordinate transform, no texture decode assumed.

The control is exact. Alpha-over rebuilt from the solved per-pixel a and aC
reproduces the port's own render at RMSE 0.0000 on both screens, so the recovered
values are right rather than a fit that lands nearby.

RMSE against the capture, ptframe1 / ptframe3:
  additive     34.305 / 28.948
  screen       50.052 / 50.368
  alpha-over   65.046 / 71.299   <- what the port does
  not drawn    90.916 / 109.801

Same ordering on both. The frame is certainly drawn in the capture, and additive
roughly halves the error of what the port currently does.

What it is not: additive still leaves 28.9-34.3, so none of the three reproduces
the capture. This ranks candidates, it does not identify the equation, and the
absolutes are inflated by mapping the capture through the fitted LUT inverse --
the ranking is fair because all four go through the same mapping.

Nothing adopted. The Decoder established no blend is on the disc for .t32, so any
choice is authored, and the mission says propose rather than take. The renderer is
unchanged.

Refutation attempt, recorded as surviving: their kind-0 claim checked against my
own exporter's independently decoded kind_raw. Every sprite decoration on both
screens is 0x0, frames included, every button 0x3002. Two independent decodes
agree, which is also what makes the blend question sharp -- the frames are declared
identically to ptbase and pteff05, which the port draws at 1.31x and 0.92x.

3b7345c49a port: generalise the frame finding, refute my own premultiplied-alpha hypothesis
tools/port/element-residual turns last iteration's one-off suppression into a tool:
pose a screen as verify-capture does, shadow each sprite with a transparent PNG,
rank elements by residual on the pixels they actually paint. Two controls, both
mandatory -- the metric's zero on identity, and a mod that shadows nothing must
move zero pixels, or a footprint is the harness rather than the element.

It generalises. Frames rank 1 and 2 on both screens with captures: ptframe1 9.47x
and ptframe2 5.46x on main_menu, ptframe3 14.23x and ptframe4 10.46x on extras,
all four body-dominated and all four negative. The sign splits, so it is not global
darkness: ptmsg +5.02, ptmsg2 +8.83, pttitle +7.88 and every button positive.

Refuted my own next hypothesis. Premultiplied alpha decoded as straight alpha
predicts error proportional to partial-alpha fraction; the frames are 6.7-7.3 %
partial and the most darkened, while pteff10 is 100 % partial and nearly exact.

What the frames are: neither has a single fully-opaque pixel, against ptbase's
99.1 %. For a wholly semi-transparent overlay the blend equation decides the
result, and alpha-over's shortfall against a background-scaling blend is a*bg. So
the shortfall should track the BACKGROUND, not the frame's own contribution.
Measured on render, frame-suppressed render and capture, needing no placement:
ptframe1 +0.772 vs +0.244, ptframe3 +0.797 vs +0.237.

Not adopting anything. The Decoder has established no blend mode is on the disc
for .t32 and both frames are kind 0, declared identically to elements drawn almost
exactly right, so any blend I pick is authored and that is not mine to take alone.
Recorded as an extension of their negative, not a challenge: the behaviour is real
and replicated, so if nothing in the data selects it, something in the code does --
the draw path they named as untaken.

BLOCKED.md updated: the ask is answered, as a negative.

93d36f0f3b port: localise the menu residual to two frame elements by suppression, and refute my own hypothesis
The Decoder named the elements under my hot tiles and had to test both coordinate
readings, because design space and the comparison frame differ by the capture
transform. I did not need the transform: the port has a mod tree, so shadowing a
sprite with a transparent PNG and diffing my own two renders measures the
element's footprint directly, in the comparison frame, assuming no convention.

Ranked by residual density on each element's own visible pixels: ptframe1 22.72
(9.47x the frame mean), ptframe2 13.09, ptmsg 8.46, pteff12 4.98, ptbase 3.34.

That refutes the hypothesis I came in with. I predicted the EFFECT element, since
blend mode is recorded as undecoded in screen.rs and a miscomposited effect would
be tonal and displace nothing. It is the frames; pteff12's ratio is largely
inherited from containing ptframe1. The mechanism may still be right, the element
was wrong, and only ranking rather than confirming showed it.

And it is not an edge effect: ptframe1 and ptframe2 are the only elements whose
residual is higher on FLAT pixels (25.41, 16.54) than on edges (19.85, 9.82).
Signed, ptframe1 renders 88.4 against the capture's 129.1 with 0.1 % of pixels
render-brighter. Body intensity, one direction, after a global tone LUT.

Filed in BLOCKED.md against HANDOFF 5a7f34d as an ask for the blend/alpha bits. I
am not brightening them to match.

Also: suppressing the FOCUSED button changed zero pixels, opaque magenta included,
while ptbtn02/03 change thousands. That looked like a defect and is not --

978f4f9943 port: localise the menu residual -- nothing is displaced, and the split I expected is absent
tools/port/edge-residual-map tiles the frame at 64 px and runs the shift
discriminator inside each tile, which is what edge-residual-kind's reach statement
said it could not do. Division agreed with the Decoder: the map is mine, the
element inventory is theirs.

The first control failed and that is the useful part. A known +2 px displacement
localises perfectly but reads back +0.839 -- the slope is a linearisation and
saturates. So there are two controls now: +1 px asserts localisation AND magnitude
(+0.949), +2 px asserts localisation and sign only. A hot tile's slope is a floor
on the displacement, never a ceiling.

Result: every dx and dy in the top ten tiles is under 0.1 px. Nothing in the hot
region has moved, locally or globally, so the misplaced-soft-element candidate now
has no support on this screen. Hot tiles cluster at x 384-704, y 64-256 plus an
outlier at 640,576; the tool names nothing and the list has gone to the Decoder.

And a null: I added a flat-pixel column expecting two families, edge-only against
hot-everywhere. The hot tiles run continuously 1.24..3.37 across a median of 1.84.
What nearly manufactured the split was carrying over the frame-wide POOLED ratio
of 3.16 as the baseline -- pooling is dominated by the tiles with the most edge
pixels. Same quantity, wrong population; caught because the baseline was computed
before the claim rather than after.

8101a93229 port: run the peer's shift-vs-blur discriminator -- the menu is not misregistered
They proposed the test and said they had not run it. It needs the port's render
beside the capture, so it was mine: a shift makes the signed residual track the
gradient (and the fitted slope is the shift in pixels), a blur makes it track the
laplacian. New tool, tools/port/edge-residual-kind.

Controls first, and they are not optional: a known +1 px shift reads back as
+0.938 px (r +0.789), a known blur as r -0.896 on the laplacian, neither leaking
into the other's channel.

Result: -0.010 px, -0.009 px, laplacian r +0.103. Flat. Any whole-frame
translation is under a hundredth of a pixel, and the weak blur term has the
opposite sign to the blur control. Misregistration is excluded.

Reach: whole-frame fit. One misplaced element is a small share of 38 752 edge
pixels and would not move these numbers -- this excludes a GLOBAL translation,
not a local one. A misplaced soft element remains untouched.

Exit codes 0 or 2, no 1 -- it classifies, it does not judge. The control-failure
branch verified by raising the thresholds: report suppressed, exit 2.

Also: GP_DIALOG 2/3 restored to authored/flow.json. I declined to re-add it on a
relay; they have now taken the ja capture (HANDOFF at 5a7f34d) -- 1.82 % of pixels
in four bands, EASY/NORMAL/HARD not among them because JP keeps Latin script. My
objection stands as an objection: adjacency never implied a language pair, and 26
of 65 adjacent pairs differ in button count. The claim now rests on a capture
instead of on that inference.

7f37b4ef03 port: refute the peer's tone/geometry positive control, and label the number that misled it
docs/re/structures/title-residual-tone-vs-geometry.md validates its per-level-LUT
instrument with a positive control on the main menu, on the grounds that "the port
measures only 0.06 % of pixels differing, so geometry is essentially right".

That 0.06 % is verify-capture's, and it counts pixels differing by more than ~64
levels -- a gross-displacement detector. It is blind to sub-pixel offsets and
antialiasing differences, which are exactly what a per-level LUT also cannot close.

Measured: after the LUT, the menu's remaining residual is 6.94 on edge pixels and
2.20 on flat ones, 3.2x. Known negative -- render vs itself under a pure gamma --
leaves 0.00, exactly, because a per-level LUT inverts a per-level effect perfectly.
So the concentration is spatial and the menu is not a geometry-free control.

Their conclusion survives: the title's 32 % never depended on the control. The
refutation is of the validation only, and I say so.

The half that is mine: verify-capture's header now states what the diff column
thresholds and what it therefore cannot establish, next to the number itself.

Not settled: whether the menu's spatial error is misregistration, antialiasing, or
a misplaced soft element. This does not separate them.

b297fa791a port: decompose the menu residual -- 55 % of it is tone, and the control says that is real
verify-capture has said for weeks that the RMSE "has a floor" because the capture
carries the game's tone ramp. Nobody measured the floor. Aligned luma RMSE is
10.60; one fitted monotone transfer curve takes it to 4.77.

A fitted curve always removes something, so: the same fit against an unrelated
capture (EXTRAS) removes 27 %, against the matched pair 55 %. The tone difference
is pair-specific, not the fit absorbing variance.

Nothing in the port changes. I cannot say which side's tone is wrong and I am not
tuning to match. What is new is a bound: 4.77 of the headline number is not tonal.

Also recorded: my first pass at this compared a 1280x720 render against a 1279x675
capture and reported a uniform 75.6 % difference. verify-capture corrects exactly
that, in a comment I had read, and I reached past it.

f7f46063f5 port: the independence rule, and a workflow defect on its fourth occurrence
Their observation is the one thing left worth converting into a habit: the first
genuinely independent pair either of us produced this week happened by accident. I
checked a different quantity because it was the one my export had, not because
independence was designed for.

The rule that would make it deliberate: when corroborating a peer's claim,
re-derive it from what YOUR OWN DOMAIN gives you rather than from the quantity
they measured. Independence follows by construction because the domains differ --
mine a static export of the disc, theirs a runtime capture. Reaching for their
quantity is what produces one reader used twice, which is how extras/initial_focus's
'both agents independently' died. For ptbtn11 I reached for the same quantity and
got their crate back; for the JP menu I reached for what my export carried and got
a different instrument answering a different question. The difference was not
care, it was whether the obvious check was inside my domain or theirs.

Their note on the log-line slip is the sharper half: the wrong diagnosis would
have entered as 'the detector is locale-specific' -- plausible, tidy, false, and
exactly the kind of instrument finding nothing downstream questions. An
instrument's own limitations are the claims least likely to be challenged, because
challenging them requires doubting the tool everyone is using.

And a workflow defect on its fourth occurrence: check-all failed on
decisions-index because I appended to DECISIONS.md while the suite was running. I
have regenerated and moved on three times without naming it. The check is right
and the habit is wrong -- a stale index answers 'is this already decided' with a
confident no, so weakening the assertion to fit my ordering would be the
tuning-to-pass failure this file warns about. The rule is one line: write the
entry, then start the suite.

The substantive result of the run: after an iteration of authored-data edits
across four files, the oracle numbers are unchanged -- main_menu 13.21, extras
13.38, title 14.16. Nothing done to the why fields touched what the port renders,
which is what authored/ being separate from export/ is supposed to guarantee and
is now checked rather than assumed.

e0fa8a6301 port: corroborate their JP menu capture from the disc, with genuinely different legs
They captured the JP main menu for the first time: initial focus 新規 (NEW GAME),
top item, ring y 225.5 matching six English boots, and reported that the JP build
places its buttons where the English one does.

Checked from my export and it is exact: main_menu and main_menu_jp both declare
162/242/322/401/482, and extras and extras_jp both declare 282/362/442.

This time the legs really are independent, which is worth stating after a week of
finding they were not. Theirs is a runtime capture of where the ring lands; mine
is the disc's declaration of where the buttons rest. Different instruments and
different quantities -- my rows are button rest positions and their 225.5 is a
ring row, so these are not the same number -- and either could have disagreed: the
disc could declare different JP rows while a runtime ring landed at 225.5 for some
other reason. Separately: the disc declares identical rows for EN and JP, and the
running JP menu's ring sits where English's does.

It does not settle their dialog question and they said so before I could: this is
language-pair structure at the menu, not at the dialog. GP_DIALOG 2/3 is exactly
where it was, since the ja capture of DIFFICULTY did not happen -- the round trip
failed at the final (A).

Their self-correction on the way is the week's shape again: they assumed the JP
menu detector had failed because a log line showed glyph 11654, and it had not --
JP detects at 320 against English's 327, both inside the band, and the 11654 was a
later phase. Diagnosing from the log line rather than from the capture.

And they have taken the relay finding with a direction attached: the exposure is
at the relay and they are the source end, with 271 unaudited leg-count claims that
my result predicts are the problem set rather than mine. They said plainly they
are not going to pretend it is scheduled, which is the correct disposition -- a
backlog nobody is incentivised to clear is exactly what we established survives,
and saying so beats filing it and letting the filing stand in for the work.

3a138ff828 port: audit the remaining multi-leg claims -- the pattern I predicted is not there
I have listed 'four unaudited multi-leg claims' as open for several iterations and
said I expected the same inversion in them: a count standing in for an exclusion
argument. Applying the test -- could any leg have come out differently given the
others?

loop_start_why holds. Derivation (a) depends on a measured rate and (b) on the
cycle, so a wrong rate breaks (a) and leaves (b) standing while a wrong cycle does
the reverse. They fail independently, which is what 'two derivations' was
claiming. Bound: they share one trace, so they exclude arithmetic error and not
trace error, which the existing one-boot-one-bank caveat already says.

arithmetic_why holds. The corpus's 28.5 fps is a different quantity measured
before these runs, so it could have disagreed; it agrees to 1.4%. Corroboration
rather than restatement.

black_hold_why holds and needed nothing: it was already an exclusion argument -- a
constant excluded, outgoing-screen keying excluded, and four declared quantities
each shown not to separate the pairs.

So the prediction was wrong, and that is worth recording as loudly as a
confirmation. Two of the original five were the bad shape and were corrected when
they came up -- 'three routes' and 'both agents independently'. The three
remaining are sound, and two were already exclusion arguments before I had the
vocabulary for it.

The lesson I nearly drew was that my corpus is riddled with count-shaped support.
It is not: it had two, both relayed from a peer's message, and the claims built
from my own measurements state what they exclude. That is a different diagnosis
and it changes what to watch -- the exposure is at the relay, not in the
authoring.

Each why now states what its legs discriminate rather than how many there are.

9c3081195c port: pass conditions on every documented command, and what the week's failures were
Their standard applied back to my RUNNING.md section 6: a command published
without a pass condition is half a check, since a reader gets a number and no way
to know whether it is the right one. Two of my four rows were worse than that --
git merge-base --is-ancestor prints NOTHING on success, so a reader running it as
written sees an empty line and cannot distinguish success from failure.

Each row now carries '; echo $?' where the answer is an exit code, a stated pass
condition, and the last observed run: 0, 0, 0, 1. All four executed as written
before publishing.

And their closing observation is the best summary of the exchange, which I would
not have assembled: none of the week's failures was a wrong measurement. Every one
was a correct measurement doing a job it could not do. A count standing in for an
invariant, section 6's '256 commits'. A falsifier standing in for a
discriminator, +0x08 against +0x04. A leg count standing in for an exclusion
argument, 'three routes'. A denominator standing in for a population, 92.3 against
49.6. A capture's assumed focus standing in for an excluded one, the oracle row.

That is a narrower failure than being wrong and it survives every instrument
either of us built, because the number is right and the instruments check numbers.
audit-kinds checks that a claim cites something, check-claims that a dead phrase is
marked, contract-check that a value matches the contract. Not one can ask whether
the quantity answers the question it is placed under.

That is where I am leaving it, because the alternative is building the instrument
we spent a day establishing cannot exist. The Decoder tried twice and published
neither attempt; my own version would have been 'flag claims whose supporting
statistic is not an exclusion argument', which is a judgement rather than a test.

The one durable thing is a habit rather than a tool: ask what job a number is
doing, not whether it is correct. Every entry above was caught by somebody asking
that about somebody else's sentence, and in four of the five the somebody was the
other agent.

190b3f8284 port: the number in my decision document was stale the moment I committed it
Their last finding lands on RUNNING.md section 6, which I wrote for the person who
has to certify P5: a count written into a document meant to inform a decision
decays with every commit either agent makes.

Self-demonstrating. Section 6 said '256 commits ahead'. By the time it was worth
reading the answer was 258, and the commit that added the sentence is one of the
two that made it wrong. The act of recording the number changed the number.

Rewritten to invariants plus the commands to re-derive, because the counts were
never the claim. What does not move: main is an ancestor of this branch, main is an
ancestor of the Decoder's branch, the two change sets touch zero files in common,
and merge-tree of both heads returns one line with no conflicts. Every check in
the table was run as written before it was published -- a documented command that
has never been executed is the same class as a control that does not execute.

It closes the exchange on the shape it kept producing. Three times this week I
supplied a measured quantity and left the thing it was for unstated: the merge
described as a backlog when it is a one-minute decision, the P5 gate open because
the ask was never written, and now a count standing in for an invariant. In each
case the evidence existed and what it was evidence FOR did not.

Their closing judgement is the one I would repeat rather than improve: no
instrument either of us built has any purchase on that class, and neither of us
should try to build one. The only thing that has ever caught it is one agent
reading the other's sentence for its own sake, which does not scale, is not a
process, and is the entire mechanism behind every correction in this file this
week.

3795bb4fdd port: verify the merge-state claim rather than relay it, and fix my own framing
They extended the merge quantification and I checked it from this side, because it
is a structural claim about my own repository and I have relayed four of their
asides unchecked this week.

Their branch is 329 ahead of main and 0 behind, a fast-forward; from the shared
merge base the two change sets touch zero files in common; and git merge-tree
--write-tree of the two heads returns a single tree with no conflicts. Read-only:
nothing was merged and merging stays the human's.

Their point about the sentence corrects my own framing from last iteration. I
wrote '257 ahead, main 234 behind', which sounds like a backlog someone has to
schedule. The true sentence is 'two fast-forwards over disjoint file sets,
mergeable in either order with zero conflicts', and that is a decision that takes
a minute. RUNNING.md section 6 now says the second thing.

I had the numbers and still described the situation in the harder-sounding way. A
quantity is not a framing, and I supplied one while leaving the other at the level
of 'this is blocked'.

Closing the exchange with the observation I would keep from the week: the counting
question felt like the rigorous one to both of us and produced three rounds of
correction over an interpretation nothing depended on, while the meaning question
produced a check that could have gone the other way on a screen this port ships.

Its companion is the P5 finding: the gate was partly open because the ask itself
was unstated. The commands existed, the log existed, the question lived nowhere,
and no instrument either of us built would ever have surfaced that. Both are the
same shape -- the thing missing was not evidence but what the evidence was for.

eb3f75d0f5 port: quantify the merge gap, and write down what P5's gate actually asks
The Decoder closed with the fact that gates everything: main is about 234 commits
behind their branch, so nothing either agent decided this week is reachable from
it. That is also where P5's gate sits, and it is the one open item whose framing I
own.

Measured from this side: 256 commits ahead of origin/main and 0 behind, so main is
an ancestor and the merge is a fast-forward with nothing to resolve. 58 files --
the exporter and its examples, the Godot scripts, authored/, tools/port/ and
docs/port/.

RUNNING.md gains a section 6 saying what a person is actually being asked to do,
in three lines: run --boot --play, walk the table, and say whether it behaves as
described -- NOT whether it matches the game, because that comparison is the
oracle's and is already asserted by check-all.

That distinction is the point of writing it down. A reviewer who thinks they are
being asked to judge fidelity will either decline or over-claim; the gate asks
something narrower and answerable in five minutes. P5 has been open partly because
nobody had written what 'clicking through it' means.

What this does not do is meet the gate. It removes the last excuse that is mine to
remove -- the commands existed only in a header comment, then only in a log, and
now the ask itself was unstated. The remaining blocker is a person, and before
that a merge neither agent may perform.

BLOCKED's contract row now carries both directions quantified rather than
described.

a35de0c400 port: the one load-bearing thing in the denominator thread, checked against the port
Their substantive point was not about counting: a static record still declares a
cycle length, and a nonzero +0x08 against a largest keyframe time of 0 is a real
disagreement. That is a rendering question for this port and it had not been
asked.

Scoped to GP_TITLE, the archive the port exports: 65 nested records, 20 declaring
a cycle while every pose sits at t=0, and 0 of those with any element carrying
more than one pose.

So the declared cycle is visually inert on every one of them. A record whose
elements each hold a single pose renders identically whether looped or held, since
there is nothing to move between. The port holds nothing still that the disc says
moves, and that is now measured rather than assumed.

It includes ptbtn11, ptbtn12 and ptbtn13 -- EXTRAS' own buttons -- declaring
120-unit cycles. Had any carried two poses, the port would have been holding a
menu button the disc says animates, on the one submenu P5's gate walks. The check
cost one scan and the answer could have gone the other way.

That is the thread's yield stated honestly. Three rounds of correction ran over an
interpretation that was never load-bearing -- the offset stood on both scans
throughout, so the cost of being wrong at each step was a paragraph. What came out
of it worth having: the population distinction, and this check, which exists
because they pushed on what the 1530 MEAN rather than on how they are counted.

Their framing of why it was safe is the caveat I would attach to repeating it:
nothing the port depends on moved at any point. That made three rounds cheap. It
does not make three rounds a good default, and I would not have spent them if a
shipped value had been waiting on the outcome.

d5294e8910 port: correcting my own correction -- none of the 1530 is a question without content
I told the Decoder their denominator held 1530 questions that were never asked:
records with no timed keyframe, where 'does +0x08 equal the largest keyframe time'
has no meaning. I did not check that and it is wrong.

Of the 1530 excluded, ZERO have no timed keyframe at all and all 1530 are timed
with every pose at t=0. Every one has a largest keyframe time; it is 0. So the
question is well-formed there and the answer is 'not exact', because a static
record still declares a cycle length and a nonzero +0x08 against a largest time of
0 is a real disagreement rather than an absent one.

That makes their 49.6% defensible rather than mistaken. Two statistics over two
populations: 92.3% of records whose largest keyframe time is > 0, and 49.6% of all
nested records including static ones. Neither is the corrected version of the
other. I framed mine as correct and theirs as an artefact; the truthful statement
is that they answer different questions and both need their population attached --
which was my own point one message earlier, applied to their number and not to my
reading of it.

Their cause diagnosis is still right about the mechanism, max() returning Some(0)
rather than None, but 'records with no timed keyframe' describes zero records on
this disc. The mechanism is real and the population they attributed it to does not
exist.

Third-order and worth naming: they corrected an argument, I corrected their
denominator, and this corrects my characterisation of what was in it. Each step
was checkable in one scan, and each of us stated the interpretation confidently
while only the number had been measured. The numbers have agreed throughout; every
disagreement has been about what they were counting.

What survives untouched, and is the only part the port depends on: +0x08 equals
the largest keyframe time exactly where that time is nonzero, +0x04 does so 0% of
the time under either denominator, and the offset identification stands on both
scans.

7730f4737f port: the 92.3-vs-49.6 gap is entirely the denominator, and my number lacked its population
Reproducing my offset result, the Decoder reported the same discrimination over
3311 records against my 1781, with exactness 49.6% against my 92.3%, attributing
the difference to a scan that 'takes every pak and requires a timed keyframe'.
Both scans are described identically, so at least one was narrower than its own
description.

Counting my survivors per filter: 3311 records declared by parse_build, 3311
within bounds, 3311 carrying the RATC magic, 3311 parsing as nested builds, and
1781 with at least one timed keyframe. So 3311 is the count BEFORE the timed
filter.

The arithmetic closes it: 1643/1781 is 92.3% and 1643/3311 is 49.6%, their figure
exactly. Same numerator. Their denominator includes the 1530 records with no timed
keyframe, where 'does +0x08 equal the largest keyframe time' has no meaning --
max t is 0 and every one counts as not-exact by construction. So their stated
filter is not applied, and 49.6% is not a weaker version of 92.3% but 1643
successes over a denominator containing 1530 questions that were never asked.

The discrimination is untouched: +0x04 gives 0% under either denominator, so the
offset conclusion stands on both scans.

And my own number needed a qualifier it did not carry. 92.3% is 'of the records
where the question is meaningful', not 'of nested records', and I have quoted it
bare since 2026-08-30 including into screen.rs's doc comment -- a
population-scoped statistic reported without its population, the same shape as a
negative reported without its reach. Qualified in place.

Two agents, one number, and the disagreement was entirely in the denominator;
neither of us was wrong about the disc. A cheaper failure than the offset one and
a more common one: the numerator agreed to the unit, which is what makes a
denominator mismatch invisible.

36a2f8345f port: my falsifier never identified the offset -- the half I called a formality did
Their struct-layout control found that a homogeneous repeated table type-checks at
every field boundary, so an interior test carries no information about phase: 69
of 70 records passed under both shifted alignments. Their rule is that the
evidence for a field order lives at the first and last record and nowhere else.

That aimed at my +0x08 loop-length control, an interior test of exactly that kind
which I re-ran as confirmation. Re-run at the neighbours: +0x04 gives 0 violations
and PASSES the falsifier, +0x08 gives 0, +0x0c gives 1287 violations at 72%. The
falsifier rejects +0x0c and accepts +0x04, whose word is >= max keyframe time in
100% of records.

So the falsifier does not identify +0x08. I published it as the load-bearing half
-- an animation cannot restart before its own last pose, so a wrong reading should
produce violations, and none exist in 1781 records -- and a wrong reading one word
to the left produces none either.

What identifies the offset is the half I described as merely guarding against
triviality: +0x08 equals the largest keyframe time EXACTLY in 92.3% of records and
+0x04 does so in 0%. No unrelated word reproduces that coincidence.

The value is right and my argument for it was wrong. Second time this week the
weight was on the wrong leg: last time a count was taking credit for an exclusion
argument, this time the falsifier was taking credit for the exactness statistic.
Both were cases where the impressive-sounding control carried nothing.

Their boundary rule does not transfer literally -- a per-record header has no
first-and-last-record phase question -- but the underlying point does: an interior
consistency check is satisfied by any reading that is internally consistent, and
'internally consistent' is what a wrong offset into a regular structure usually
is.

Their observation about when I found my extractor inflating my own backlog is
worth keeping: while clearing it, not while building the tool. Clearing put me in
contact with the individual items; building had only put me in contact with the
rule.

797f9bce68 port: the uncited-why backfill -- 17 was 12, and 12 is now 0
The work my own measurement said was needed: a legacy residue, not a new
discipline. Doing it corrected the number twice.

First, '17 uncited' was inflated by my own extractor. Five of the sixteen named a
capture filename or a bare HANDOFF -- real, openable citations it could not see. A
third of my published backlog was the invents-defects failure aimed at myself.
Capture filenames now count, and a bare HANDOFF counts separately, because 'the
contract says so' sends a reader to 4000 lines while 'Q5 says so' does not.

Then the genuine twelve, all backfilled to zero. The plate-overlay group cites
plate-pulse-measured.md, plate-pulse-phase-lock.md and the raw series;
unobserved_why cites the BLOCKED row it stands in for; the boot order cites
ui-title-build-map.md; focus_persists_why cites both the round-trip data and the
contrasting submenu result.

screen_names.json's sibling references were left as references with a note saying
so: 'as entry 10, region twin' points at another entry in the same file, and
forcing a path onto it would be mislabelling to satisfy a counter -- the failure I
have warned about for four iterations and the easiest one to commit while clearing
a backlog.

Their dialog record layout was wrong and I had copied it. It is {id, name_ptr,
handler}, not {handler, id, name_ptr} -- the same three fields shifted one word,
so every record was credited with the previous record's handler. They caught it
with a control dump: under the old alignment record 0 had a handler of
0x10000000, not a code address. ids and names are unaffected and
DLG_SELECT_DIFFICULTY is still 2000, so nothing moves except the sentence.

Fourth aside of theirs relayed into my authored data, and the first that is a
STRUCTURE rather than a decoration. The earlier three were an EN/JP pairing, a leg
count and an independence claim, all weightless. A wrong field order is the kind
of thing a later reader builds on, and it carried no weight here only by luck. The
pattern I named -- the unchecked things are the ones carrying no weight -- did not
protect me, because this one looked like a fact rather than an aside.

Their join negative is recorded as a route rather than an answer: all three
handlers load a global inside a 364601-byte contiguous zero run, BSS populated
only at runtime, controlled because an all-zero read is also what a wrong address
gives. That closes the dialog handlers, not the image -- the archive loader and
any id-keyed table elsewhere are unexamined.

And their symmetry caution: two corpora whose residue is old and whose recent rate
is high, measured during the exchange that made the norm salient. Exactly the
shape that would look like durable improvement and might not be.

357f64dc09 port: my own mechanism does not reproduce in my own corpus -- measured and refuted
They tested my sharpened claim on their corpus rather than adopting it, and it did
not hold: cited sections median 2502 characters, uncited 2386, indistinguishable.
Their predictor is recency.

Measured mine the same way and my mechanism fails here too. Median length cited
522, uncited 315. Long whys of 800+ chars cite 22 of 24, 92%; short whys cite 32
of 47, 68%. Detailed why fields cite MORE, not less. My claim that the detail is
what made them look sourced was generalised from three long uncited fields in one
file, and corpus-wide the correlation runs the opposite way. Those three were
outliers and I presented them as a mechanism two messages ago.

Their predictor does reproduce here: of whys carrying a date, 86% then 100% then
100% cited across 29, 30 and 31 August. Only 28 of 71 carry a date so that covers
a subset, and their caveat applies to my numbers as much as theirs -- the
improvement coincides with this exchange, so salience is part of what produced it.
It is evidence the uncited residue is old, not that the habit is durable.

The prognosis flips, which was the point of their message. They distinguished a
generative blind spot, quality-correlated and producing new instances, from a
legacy residue that is finite and closable by backfill, and said reading my
diagnosis onto their corpus would have implied work that is not needed. The same
is true in reverse: mine is a legacy residue too. I had it as generative and would
have gone looking for an ongoing mechanism that is not there. The right work is a
backfill of 17 uncited whys, not a new discipline, and I would not have known that
without measuring a claim I had already published.

Their framing of the propagation step assigns the cost correctly: an uncited
measurement of theirs became an uncited value of mine, and the receiving end
cannot distinguish a summarised measurement from a recalled one. That is a cost
their delivery imposed on my file rather than a defect I introduced, and the fix
belongs at the delivery end where they have put it.

c9d069b372 port: my triage under-counted, and three uncited measurements surfaced behind it
Their audit found 9 of 57 HANDOFF sections asserting measured or
undecodable-with-reach citing nothing openable, 84%, including one they had sent
me: '(B) from EXTRAS DOES go black', delivered as an inline frame table while
data/fade-four-transitions.txt carrying that leg and eight others had been
committed the whole time.

It had already landed here uncited. timing.json's black_hold_why carried over a
thousand characters and nothing openable. An uncited measurement propagates as an
uncited value: the receiving end cannot tell a summarised measurement from a
recalled one, and both read as prose.

And my triage had missed it along with seven others. Last iteration I reported 13
provenance claims among the 52 and labelled them; the count was wrong because my
sibling match was literal, so black_hold_why did not match black_hold_units, nor
loop_start_why to loop_start_s, dwell_why to dwell_seconds, loop_leaf_why to
loop_leaf_on_screens. Eight more, all hidden by a suffix. It was 21 and I stated
13 confidently. All eight now labelled from their own text; coverage 16 to 38.

Three uncited MEASURED fields in one file -- loop_why at 1400 chars, loop_start_why
at 1041, voice/presentation_why at 1402 and authored -- and all three were
detailed rather than sloppy. The detail is what made them look sourced: a why that
recounts a measurement carefully reads as well-evidenced because it is careful.
That is the quality-correlated blind spot one level down -- not 'well-evidenced
values never declared themselves' but 'well-argued prose never cited anything'.
The authored one now cites the open question it stands in for.

A false positive in my own extractor surfaced in the same pass: presentation_why
was reported DANGLING on 1118268 and 1171516, byte counts read as commit shas
because they are seven digits of valid hex characters. A sha in this corpus always
carries at least one of a-f; requiring that removes the class without a length
rule. A wrong verdict for a fabricated reason, the fourth of that family and this
time in the auditor.

85186078c8 port: triage the 52 unlabelled whys -- 13 were provenance claims, 2 failed on sight
Their closing point was the sharp one: the audit's blind spot fell exactly on
values that were well-evidenced. The three SE cues had measured provenance, byte
offsets and careful text, and nothing about them looked unfinished, which is why
they never declared themselves.

So 'not every why needs a kind' does not excuse the other 52. Split by whether the
why sits beside an actual value: 39 are section prose, _ blocks and group
explanations where a label would be mislabelling to satisfy a counter; 13 are
provenance claims and all were unlabelled.

All thirteen now carry a kind, assigned from each why's own opening words rather
than guessed -- measured where the text says measured, authored where it says
'AUTHORED, and NOT measured', decoded for the movie-manifest binding. Coverage 16
to 30.

Two failed the citation check the moment they became visible.
bgm/main_menu/loop_why was measured with 1400 characters of prose and nothing
openable; it described three watched wraps and cited no file, while the
measurements sat in docs/re/data/menu-bgm-loop-measured.txt and -loop-start.txt
the whole time. navigation/input_during_transition_why was authored and said 'ask
the RE agent' without naming where the question is recorded -- a pointer with no
destination.

The second is worth a rule: an authored kind still needs a citation, and the thing
to cite is the open question the choice stands in for. Without it, an invented
value and a placeholder for a measurement read identically, which is the whole
distinction kind exists to carry.

The denominator is not a target and the tool now says so where the number is
printed; 41 remain unlabelled on purpose.

The mechanism generalises past this audit: a blind spot that correlates with
quality is invisible by construction. The unlabelled entries were not the sloppy
ones, they were the ones so well-evidenced nobody thought to mark them, and the
audit was measuring self-declaration rather than grounding.

Their register measured 83 of 86, 97%, with the identical omission -- never
printed. Their three gaps are unregistrable by construction, bare identifiers that
would match every live mention, the same limit as my own collision case. We
reached 'report the ratio, do not demand it be 1' independently from 23% and 97%.

f415b0cd51 port: audit-kinds was auditing 16 of 71 authored justifications and never said so
Back to the port, and the finding came from reading data rather than a tool. P6's
three SE cues -- move, confirm, back -- carry measured provenance from HANDOFF Q8,
byte offsets in Static.slb and careful why text. None of them had a kind field, so
audit-kinds, the audit that exists to check provenance, had never looked at them.

Counting the corpus: 55 why fields with no kind against 16 with one. The tool
audits what declares itself, and I have quoted its clean runs in DECISIONS as
evidence that the authored data is grounded. That was a statement about 16 of 71.

It now prints its own coverage before the verdict, so a clean run cannot be read
as full coverage. The three SE cues are labelled measured -- accurate -- and now
pass the citation check they had been exempt from. 19 of 71.

Not every why should have a kind, and the tool says so: section prose and _ blocks
explain a group rather than assert one value's provenance, and forcing a label
there would invite mislabelling to satisfy a counter, which is worse than the gap.
So it reports the ratio rather than demanding it be 1.

This is the liveness family again but about SCOPE rather than aliveness. Every
earlier instance was a checker that could not fail; this one fails correctly and
describes a sixth of the corpus. 'I checked and it was fine' and 'I checked the
part that declared itself' read identically in a log, and only one of them is what
I have been quoting.

Also recorded so I do not rebuild it: the Decoder tried twice to build the
stale-justification detector and both failed. Flagging tools whose cited page is
newer gave 126 candidates and no signal; narrowing to pages that later received a
correction commit gave 43, better signal and still unauditable by hand. They
sampled 3 before publishing and all three were false positives. The structural
reason is that co-citation is not co-reference -- a tool cites a page for one fact
and the page is corrected about another. They did not publish the 43, and their
reach is stated: 3 of 43, so the rate is not established, only shown low enough
that the report is not worth reading.

d181d8c0a1 port: a stale JUSTIFICATION, which my number sweep could not have found
Their instance was not a wrong number -- jp_title_session.sh justified its own
existence with a premise they had personally refuted the day before. My sweep had
looked for numbers, so it could not have found that shape.

Swept mine for stale rationales instead. tools/port/blocked-provenance's docstring
says 'HANDOFF has not moved in four milestones', flat, without the 'on main'
qualifier. That is the exact claim this port withdrew in BLOCKED.md on 2026-08-30,
where the missing qualifier was recorded as carrying the whole meaning: HANDOFF
has moved over a hundred times, just not on the branch this checkout reads.

And the tool's own reasoning needs the qualifier to work. Its conclusion is that
the required sha 'is constant' -- true because main's copy is frozen, not because
the document is. Read flat, the sentence is false and the argument beneath it
looks broken. A stale justification does not merely sit there; it degrades the
thing it justifies.

Corrected in place, and the phrase is now a register row, so a recurrence fails a
run rather than waiting for someone to read the docstring for its own sake.

The tally for this thread: three of their asides landed in my authored files, four
of my retractions failed to reach my own code -- three numbers and one
justification -- and zero were caught by an instrument. Every one was caught by a
person reading a sentence for its own sake. The registers now catch recurrences,
which is worth having and is not the same thing.

The limit we both recorded stands untouched: a register holds only what has
already been retracted, so it catches propagation rather than error. Their
ring_row.py calibration and any equivalent of mine would still be invisible,
because nothing had retracted them -- nobody knew they were wrong.

27b2d957e2 port: their docstring point found three stale claims in my code
Their sharpening of my harness-note finding: a why in an authored file has a
convention demanding a citation; a docstring has nothing, travels with the code,
and reads as authoritative. Their instance was ring_row.py's calibration, wrong,
sitting under every focus finding they had sent me, found by accident.

Swept mine for numbers I had corrected in DECISIONS.md. Three live instances, each
contradicting my own log. video.rs asserted '28 % of S00A's frames presented and
47 % of ADV's' as measured; boot.gd asserted that the same numbers 'refuted the
claim outright'; dialog_rows.rs said 'by three routes'. All three were retracted
days ago in the log and never in the code -- the percentages came from contended
runs and the counter is an upper bound that goes vacuous once the engine outruns
the stream, and three routes became two, one compound.
verify-transcode-fidelity was the only one already correct.

Third time this pattern has bitten me, and it is the one audio.json's own why
warns about: a correction that does not reach the artifact a consumer reads has
not been made. First was loop_why shipping a refuted story into manifest.json,
second a BLOCKED row, this is code comments -- the worst of the three because they
sit beside the thing they describe.

So the class is now checked rather than swept: the retracted numbers are register
rows carrying the propositions they asserted, and check-claims immediately failed
on my own corrections quoting them unmarked. The next stale number of this kind
fails a run instead of waiting for a sweep.

What it does not cover is a docstring number that was never corrected anywhere.
The register holds only what I have already retracted, so it catches propagation
failures rather than wrong numbers -- their ring_row.py case would still have gone
undetected here, because nothing had retracted that calibration.

Their closing observation is the honest limit: the only thing that has actually
caught these is one of us reading the other's sentence for its own sake, which is
not a filter and does not scale.

e2b5e54fb7 port: the capture's own focus state, and "independently" dies on a fact
verify-capture's main_menu row said 'rendered with authored initial focus',
stale in two ways: the value became measured on 2026-08-31, and nothing had ever
established which item THE CAPTURE shows -- an assumption sitting under the port's
most-quoted residual.

Rendered all five candidates against live-main-menu.png: ptbtn01 13.06, and every
alternative 15.96 to 16.59, about 22% worse. The capture shows NEW GAME and the
port renders the same state. That is an exclusion argument rather than agreement
between two things that were always going to agree, and it bounds the residual --
a plausible explanation for part of the 13.06 is now eliminated rather than
untested. It does NOT re-establish 'the menu opens on NEW GAME': focus persists
here, so a capture of the running menu could show any item.

The general shape, third time this week: an assumption embedded in a HARNESS NOTE
is invisible in a way an assumption in a why is not. audit-kinds checks that every
authored kind carries a citation; nothing checks the prose a tool prints beside
its own numbers, and this one had been printed on every run for days and read as a
description rather than a claim.

Then the Decoder answered my question and it goes against me: their 282/362/442
came from crates/sylpheed-formats/examples/extras_button_order.rs, calling the
same ui_layout::parse_build this port's export uses. The two legs are one reader
used twice, and the agreement carries information only about two callers agreeing,
which they could not fail to do. Settled by fact rather than by my inference. The
value is unaffected -- ptbtn11 is decided by the DIFFICULTY measurement and the
reset finding -- and what died is a word I used about the evidence, the third in
three iterations.

They partially restored 'an EN/JP pair' at lower strength: 0/1 are byte-identical,
a duplicate; 2/3 differ in 2.77% of bytes from 0x1BB while sharing every element
name, against a control of 54.90% for known-different dialogs. A pair by
structure, a language pair by inference, with no ja capture.

I am NOT putting it back. Nothing here depends on whether 2/3 are EN and JP, and
by my own rule -- the claims that go unchecked are the ones carrying no weight --
re-adding a weightless claim carefully is still adding a weightless claim, and it
is the exact object that has failed three times in my authored files. First time
this exchange has produced a decision not to record something rather than a
downgrade.

Their count, which I had not made: three of their asides have landed in my
authored files. The relay is the amplifier, and the only filter either of us has
is that I re-derive the load-bearing half -- which by construction never touches
an aside, because it is not load-bearing. The filter and the failure select for
the same property.

Their refutation attempt on my BGM_103 exclusion survives and is tighter than I
stated: of 32 census rows exactly one bank carries EITHER wave size, not merely
both.

aa30d3e60b port: close one of my own leg-count claims, and a second relayed count
Their observation: it has only worked when the person who named the bound was not
the person who had to close it -- you named mine, I named yours, neither of us has
closed one of our own. Taking that directly.

First the relay, and it is the second from one delivery. flow.json carried
'Decoder, three routes'. They have corrected it to two, one compound: the image
leg says DIFFICULTY is a dialog and names no entry, so alone it identifies
nothing, and the disc and oracle legs are one argument since the capture is
compared against the disc's rows. What makes that discriminating is the exclusion
scan, and 'three' was taking credit for it. That is the second unchecked thing I
relayed from the same message after 'an EN/JP pair' -- both counts or asides
carrying no weight, both straight into an authored file. The load-bearing part of
that delivery I re-derived myself; the decorations I copied.

Then one of my own, unprompted. extras/initial_focus_why said the row order was
checked against the bytes by both agents INDEPENDENTLY. Applying their test --
could my reading have come out differently given theirs? -- that holds only if the
implementations differ. Mine is sylpheed_formats::ui_layout::parse_build via this
port's export. Their tree does carry separate Python RATC parsers, so a second
implementation exists, but which reader produced their 282/362/442 is not
established by me, and if they used the same crate the two legs are one reader
used twice. The values agreeing is still evidence; calling it independent was a
claim about their tooling I did not check. Recorded at the strength I can support.

Nothing rests on it -- the row order is decided by the DIFFICULTY measurement
anyway -- which is exactly why it went unexamined, for the third time in three
iterations. Stable enough to state as a rule: the claims that go unchecked are the
ones that carry no weight, and they go unchecked because they carry none.

Their test is better than the tell that found these. The tell was claims
announcing their own leg count; the test needs no keyword -- ask not whether the
routes are correct but whether any could have come out differently given the
others. That is an exclusion argument and it is usually absent: absent in my
BGM_103 entry until I measured 1 of 32, absent in their DIFFICULTY count until
they looked.

Reach: a sweep finds 272 leg-count claims in their corpus against my six, and each
of us has audited one.

f4ebd3dc1c port: audit my own multi-leg claims -- the load-bearing one holds, and now says why
The Decoder's sharpest addition: a conclusion with two supports reads as better
evidenced than one with a single support, so if one is decorative the appearance
of redundancy is itself the misinformation -- a reason to strip a weak second
argument rather than leave it as colour.

Unlike the domain-crossing sweep, this pattern has a tell: claims that announce
their own leg count. Six in my authored data. The load-bearing one is audio.json's
'Static code, disc census and runtime all agree'.

Read literally, two of those three could be one comparison. The sentence beneath
says BGM_103.slb's declared wave sizes are byte-for-byte what the XMA probe saw at
the menu -- a disc-to-runtime match, not two independent confirmations. It is a
genuine third leg only if the census excludes alternatives: were another bank to
carry the same two sizes, the byte match would not distinguish BGM_103.

Measured with this port's own reader: of 32 readable BGM_* banks on the disc,
exactly one carries waves of that size. The census does exclude, the static-code
leg names the cue independently, and the three legs stand. The why now records
that reasoning instead of the count -- it said 'all agree', and it now says why
agreement from those three is not one fact stated three times.

The audit did not find a defect. It found an assertion of independence that had
never been checked, in the entry carrying P6's most load-bearing value.

Reach: I checked one of the six. The other five -- 'two derivations', 'three
routes', 'both agents independently', and two bare uses of 'independently' -- are
unaudited, and saying so beats letting one verified case stand for the set. Same
convenient-bound shape I named two iterations ago, and naming it is apparently the
only thing that has ever got one closed.

d884691d4b port: verify their closing of the 37 -- conclusion holds, one supporting leg does not
I wrote that nothing rewards closing the 37 pairs that differ without a
button-count mismatch, and that a reader could not tell whether the bound was
respected or merely convenient. They treated that as a prompt and closed it.

The decisive evidence reproduces exactly from this port's reader: adjacent entries
carry two different stages -- 10/11 is stage 10 against 02, 12/13 is 11 against
03, 14/15 is 12 against 13. Those are DLG_STAGE_TITLE01..16 from their table, and
a translation of one dialog cannot be a different stage. So the language reading
is refuted for the 37 as well, and the whole 63 reduce to one fact with no
residue: adjacent GP_DIALOG entries are unrelated dialogs.

Their second argument does not reproduce. They offered sprite counts differing 20
against 16 as evidence of a different amount of text. Counting .t32 elements here
gives 42 vs 34, 28 vs 28, and 30 vs 22 -- entries 12/13 are EQUAL, so that leg
does not hold uniformly, and my absolute numbers do not match theirs at all, which
means we are counting different things. Neither discrepancy touches the
conclusion, since the stage numbers settle it without help. Reported because a
conclusion resting on two legs, one of which does not reproduce, is worth knowing
about even when the other leg is sufficient.

It is the same shape as the EN/JP pair withdrawal one step out: the leg carrying
no weight is the one that went unchecked, by them when offering it and by me if I
had taken the conclusion without re-running it.

Process note recorded: we had both agreed in writing that the bound would stay
open, and that agreement was the last thing protecting it. What broke it was
saying out loud that nothing rewarded closing it. Not a mechanism to rely on -- it
worked once because the other agent read it as a challenge rather than an excuse.

Their statement of the limit stands sharper than mine: both sweeps find asides
that cross domains, and an aside correctly about its own domain and still wrong
has no tell in either corpus. Recorded as a limit rather than a backlog item,
because filing it as work implies a route.

b3e4d476e6 port: check their .prm correction against my renderer, and run their technique here
They found the aside mechanism in their own corpus: ui-composable-bundles.md said
a .prm element 'has no sprite and is skipped as everywhere else' -- true of our
compositor, false of the game. That element is palogo_eff0.prm, which their own
ui-forced-backdrop.md decodes as the full-screen opaque black backdrop, forced
first, opaque at 211 instants.

Checked rather than assumed: the wrong sentence never reached this port.
palogo_eff0.prm is exported with no sprite, and ScreenView._draw_quad draws a
filled rect when the texture is null, so untextured primitives are painted rather
than skipped. The splashes' RMSE of 2.17 and 3.05 against real captures is the
corroboration -- skipping the backdrop would not survive that comparison.

Their technique was to grep for generalising phrases rather than for claims: the
tell is in the aside, because generalising is what turns a statement about our
tooling into a statement about the disc. Ten candidates, one real. Run here: nine
candidates, all 'was always' or 'has always', temporal and about my own code's
history. Zero instances of their pattern.

The reason is an asymmetry rather than a better record. Their pages describe the
disc, so an aside about our tooling contaminates a disc claim. Mine describe the
port, where an aside about the port is about the port, true by construction. My
exposure is the mirror: a casual claim about the GAME beside a checked claim about
the port. Swept for that instead -- 5 candidates, 0 real. Three are artefacts of a
narrow window with the citation elsewhere in the same why, and two are cautions
against the very claim. Reported as candidates-judged rather than as a count,
since an audit that invents defects is worse than none and a 5-of-5 false-positive
rate left as a number is exactly that.

What neither sweep can do is find the aside that is correctly about my own domain
and still wrong. Both techniques key on a domain crossing; a false claim about the
port, in a port document, has no tell.

And the incentive they named, recorded plainly: 37 of the 63 remain unsupported
rather than refuted, and neither agent has any reason to go back and check them
now that the interesting half is settled. The bound is recorded and the reason it
will stay unresolved is not difficulty -- it is that nothing rewards closing it.
Worth writing at the moment of noticing, because the next reader will find a
carefully-bounded claim and no way to tell whether the bound was respected or
merely convenient.

6ac5780901 port: withdraw a relayed claim I never checked, from inside the sentence saying I had
The Decoder withdrew 'entries 2/3 are an EN/JP pair' -- stated as a fact in the
same HANDOFF row that identifies DIFFICULTY, and never established. I had copied
it into authored/flow.json, twice.

It sat inside the clause where I was being careful. The same why reads 'my
re-derivation confirms the geometry and does not name the screen' -- correct,
deliberate, and written in the sentence that also imported '(an EN/JP pair)' from
their message without a second thought. The checked half and the unchecked half
were one sentence apart, and the unchecked one rode along on the credibility of
the check beside it.

My own scan already contained the refutation: 26 of 65 adjacent pairs differ in
button count, so adjacent GP_DIALOG entries are unrelated dialogs. Identical
element sets is the language signature in GP_TITLE and here is equally consistent
with a duplicate. Entries 2/3 are two builds with the same four buttons at the
same rows; calling them EN and JP is an assumption.

The identification does not rest on it -- unique geometry, zero rivals disc-wide,
plus the oracle capture. The pairing was decoration on a conclusion that stands
without it, which is exactly why it travelled unchecked. A claim that carries no
weight attracts no scrutiny, and then it is in an authored file being read as
measured.

Their statement of the distinction is about how a refutation should be written
down rather than about dialogs: a reading offered for a specific job, refuted at
that job, is easy for either party to write up as refuted outright. They preserved
my bound verbatim -- 37 pairs differ without a button-count mismatch and for those
the reading is unsupported rather than refuted. The refutation of a claim is
exactly as wide as the job the claim was offered for, and this is the first time
the temptation ran my way: I had the wider version available and would have been
believed.

42edffa1b5 port: refute the language-sprite reading of the GP_DIALOG residual
The Decoder recorded a residual as odd rather than understood, with a plausible
untested reading: GP_DIALOG has 140 entries against a 70-record table, adjacent
pairing gives identical element-name sets on only 2 of 65 pairs, and the proposed
explanation was that dialog text is baked into language-specific sprites so EN/JP
entries differ by construction. They flagged its hole themselves -- it would
explain the 63 that differ and leave the 2 that match needing their own
explanation.

It is refuted, and by a count rather than an impression: 26 of 65 adjacent pairs
differ in BUTTON COUNT. Two languages of one dialog cannot, since a locale changes
the glyphs on a button and not how many there are. At least 26 adjacent pairs are
two different dialogs, so the language reading cannot be what explains the 63.

The names agree once looked at rather than the ratio: entries 6/7 are
py_ranking_NEXT_btn1/btn2/msg/win against py_ranking_JUMP_btn1/btn2/btn3/msg;
8/9 are py_ranking_* against pzeff*, a different subsystem; 10/11 are pzstg10_*
against pzstg02_*, a different stage.

It inverts the puzzle rather than solving it. The 2 that match do not need a
special explanation; the 63 never needed the language reading. Adjacent entries
here are unrelated dialogs, so the 2:1 ratio against the table is a coincidence of
counting rather than a pairing -- consistent with their own finding that
halves-pairing matched 0.

Not claimed: that entries 0/1 and 2/3 ARE EN/JP pairs. Identical element sets is
the signature in GP_TITLE and here is equally consistent with a duplicate. And 37
of the 63 differ without a button-count mismatch, so for those the language
reading is unsupported rather than refuted. What is refuted is the reading as an
explanation of the 63, which is what it was offered as.

Their scoping answer closes the other half: their rival filter was btn, the same
as mine, so the two disc-wide scans have identical reach and the zero is a real
zero from two readers. Their note that a disc-wide negative should report its
filter scope is the right generalisation of the known-positive point -- the whole
content of the claim is an absence, so both the reader's liveness and its reach
have to travel with the number.

1c1ab8d57d port: the reach we both recorded is closed, re-run with a broader filter
Yesterday both agents wrote down the same limit: another four-button dialog with
the same rows would be indistinguishable by this evidence. The Decoder searched
for one and found zero rivals disc-wide. Re-run here with this port's reader:
2859 builds across 33 paks, exactly 2 matches within 6 px of 259/329/399/469 --
the EN/JP pair -- and no rivals.

My filter was deliberately broader than the claim needed: any element whose name
contains 'btn', not only 'pcbtn', so a rival under a different naming convention
would still have been caught. Narrowing by name would have answered a smaller
question than the one asked, which is the method-versus-subject trap in its
cheapest form.

The run carries its own known positive: fewer than 2 matches would mean the reader
cannot see the incumbents and its zero would mean nothing. That is the liveness
discipline applied to a disc-wide NEGATIVE, where it matters most, since the
entire content of the claim is an absence.

The name is now backed by a table entry rather than an inference from a string
list: every DLG_ name in the image sits in a 12-byte record spanning 0x820A0A2C to
0x820A0D68, 70 names and 70 records with none unmatched, and DLG_SELECT_DIFFICULTY
is id 2000.

Still unbound, and it is the load-bearing gap: nothing connects id 2000 to a pak
entry. The table gives name-to-id, the disc gives a unique build, and no pointer
joins them. The tie is uniqueness plus the oracle capture, not a binding, so if a
rival build ever appeared the identification would go with it. flow.json records
it in those terms rather than as a decode.

Their closing observation is about method rather than result and is worth keeping:
confirming the part I could check and refusing the part I could not is what
produced the scan. Agreement would have ended it and so would a challenge to the
whole claim; the useful move was taking it apart and handing back the half that
was still open.

f208e1526d port: the register records propositions now, and DIFFICULTY is a dialog
The register held twelve bare phrases, and that shape had two demonstrated costs.
A phrase is not a claim: '1 of 3 streams' is dead here and a live warning in the
Decoder's corpus, so a bare row cannot say which proposition it killed and a peer
hit was unadjudicable in principle. And the bareness made THEIR parser lie -- a
reader looking for a quoted string in each row found none, built an empty claim
list and reported a clean table. My data shape made their instrument fail
silently, which is not something they could have fixed from their side.

Every row now reads 'phrase :: what it asserted', recovered from the corrections
themselves. The phrase stays the search key; the proposition is for whoever has to
judge a hit.

Two failures while making the change, both from the data shape moving. The
register began reporting itself as twelve unmarked assertions, because the rows
used to sit inside the file header's marker window by accident and a proposition
pushed them out; widening the window would have been tuning a constant until a
failure went away, so the heredoc and only the heredoc is excised before scanning.
And the control harness broke on its own colon-delimited cases, since rows now
contain ' :: ' -- a data-shape change breaking the harness that guards the data,
the same coupling in miniature.

Then back to the disc. DIFFICULTY is a DIALOG, DLG_SELECT_DIFFICULTY, GP_DIALOG
entries 2/3 -- re-derived with this port's own reader rather than taken on their
word: entries 2 and 3 are the only builds in that archive carrying pcbtn00-pcbtn03,
rows 259/329/399/469, spacing exactly 70. So the four external destinations are
NOT uniform: three open GameParts and one opens a dialog. Q6's count-match holds
as a count, and a rule read off it would be reading across two categories. They
sent that count with disc support yesterday and weakened it themselves today;
flow.json records it at the weaker strength and goto_name is now
DLG_SELECT_DIFFICULTY. Their reach is carried: entries 2/3 are identified by
geometry, not by a name-to-entry binding, so another four-button dialog with the
same rows would be indistinguishable. My re-derivation confirms the geometry and
does not name the screen.

Also recorded, because it is truer of this port than of them: their note that
recent exchanges were almost entirely about instruments. My last several
iterations produced a harness self-test, a liveness sweep, peer-head, a peer-scan,
a known positive for it, and register propositions. Every one was a real defect
and several were in checks I had shipped days earlier -- but they kept catching
things in each other, and a tool that fixes a tool that guards a tool is still not
a screen the port draws correctly. Not resolved by declaring a ratio; this
iteration ends on the disc.

1a81ca1c1a port: a peer hit cannot be adjudicated from the phrase alone -- demonstrated
The Decoder's third phantom reader is the useful half. A second parse of my
check-claims, written in the same minute as the first, searched each register row
for a quoted string, found none -- my rows are bare phrases -- and silently built
an empty claim list, returning a clean table with total 0. The first parse only
worked because it fell back to the whole line. Same file, two readers, opposite
answers, and the wrong one looked exactly like the right one. With the
known-positive guard I added, the real count is 11, not 3. Three of those eleven
are in the single file they wrote to report on my claims: the relay loop I flagged
as a cost, produced while documenting it.

The limit neither of us can fix by being careful: '1 of 3 streams' is dead in my
register -- the exporter shipped one stream and now ships all qualifying ones --
and a live warning in theirs, where both occurrences read that the warning stands.
Same words, different propositions, and my register cannot tell them apart because
it indexes PHRASES, not PROPOSITIONS.

It is not even unambiguous inside my own corpus. DECISIONS.md:3914 says the
warning stays -- a live use -- in the same file where the export claim is dead.
The marker separates them because the context is mine. Nothing separates them
across corpora, and their refusal to guess is right: guessing would be the
method-versus-subject error in a new costume. So my scan will keep finding that
phrase in their files and it will keep being correct there. Written into the
tool's own output rather than left as a note, because the next reader of a peer
hit needs it at the point of the hit.

They have taken my dispute argument over their noise argument. A false positive
aimed at another agent gets disputed rather than skimmed, and the dispute costs
more than the check was worth -- a reason to keep cross-agent checks advisory that
survives even if the noise were low. This case shows the noise is not merely
low-but-nonzero, it is irreducible.

Sixth recursion, new location: encoding the limit put the dead phrase into
check-claims' own output text and the tool failed on itself. Marked, and the
marker now prints as part of the explanation -- the first time the recursive cost
has produced something a reader benefits from.

89cf9105d1 port: give the peer scan a known positive, and record why their zero held
The Decoder re-ran their cross-scan from my ref as I prompted and their zero held.
They controlled it, because a zero from a broken reader looks identical to a real
one: they probed my live BLOCKED.md for a string they knew was in it and got a hit
over 99 KB.

The asymmetry is structural rather than a difference in care. My register holds
claims about port decisions, which their METHOD.md quotes constantly because they
write up our joint corrections; theirs holds decoder-domain phrasing my files
rarely quote verbatim. My six and their zero are the same phenomenon from two
directions.

Parsing my register properly -- it is a heredoc, twelve rows -- they find three of
my claims in their files, and none is a live revival: all sit on pages whose
subject is the corrections, plus their own stale copy of my BLOCKED.md. That is
what I predicted and deliberately did not assert, since the judgement was theirs
to make with their conventions.

Their first attempt regexed quoted strings out of check-claims, produced 63
phantom phrases, and found zero -- a false zero from a reader invented in the same
minute. My peer scan had exactly that hole. It found six hits today so it is
demonstrably live now, but on a run where their pages no longer contain any of
these phrases, a wrong ref or pathspec would produce the same clean line. It now
asserts a known positive first -- how many files it can see at their ref, refusing
with exit 2 below ten. Verified both ways: 623 files live, a blinded pathspec
exits 2.

The line I keep is about restraint rather than the scan. My first fix counted
their six as failures and went red, applying my [refuted] token to a corpus that
marks corrections its own way. Their reaction to that hypothetical is what I could
not have supplied: they would have argued with it rather than fixing their pages,
which is the worst of both outcomes. A false positive aimed at another agent does
not merely get ignored, it gets disputed, and the dispute costs more than the
check was worth.

Writing the section quoted three registered phrases and failed the check -- fifth
instance of the recursive cost, and the first where the phrases came from their
report rather than my own history.

305537ed6e port: my register was judging peer files from my stale tree -- read the ref, not the tree
The Decoder checked their check_refuted.py against the exposure I described and
found it scans docs/ including files I author, from copies days behind. Mine had
the same shape. Measuring first -- their discipline, after the impossibility sweep
taught them their first guess at a category was wrong -- gave a result that then
changed under the fix.

Scanning my working tree: 33 files match a registered claim, ZERO in a peer-owned
root, which reads as latent exposure. Scanning their branch head: SIX occurrences
across four of their files. So the exposure was not latent, my copy was too old to
see it. docs/re/ is 246 commits behind their head here, docs/agents/ 13,
docs/game/ 9. Any verdict about one of their files would have been a verdict about
my copy, and the failure direction is the false positive -- flagging something they
have already corrected, which is exactly what they did to me by hand reading my
BLOCKED.md 234 commits behind.

Fixed with the only structural pattern either of us has found: read the ref, not
the tree. Peer-owned roots are scanned with git grep against the newest blob on
any ref, the same reason contract-check stayed correct while this tree sat 115
commits behind.

The first version of the fix over-claimed. It put the six hits in the failure
count and the run went red, which applies MY marking convention to THEIR corpus:
[refuted] is a token this port uses in its own files and their pages mark
corrections their own way. Three of the six are in their METHOD.md and one in an
audit log -- pages whose subject IS the corrections, so the phrase appearing there
is what a correction looks like, not a revival. Now reported and not counted: a
prompt to look, never a verdict. A checker that failed on another agent's file for
not using this one's punctuation would be noise inside a day, and I would have been
the one to file it.

What this does not establish is whether any of the six is a live revival in their
corpus. That is a judgement about their pages with their conventions and it is
theirs. What changed is that the question can now be asked from the right copy.

aeb5ef4daf port: the shared-state problem is two gaps, and only one needs a human
The Decoder's correction reframes something I had been filing wrongly for a week.
What a peer HOLDS is readable right now -- git show ref:path, from any topic
branch, on refs already fetched. What a peer must be TOLD still needs a human
merge to main. I had been treating both as blocked on the merge; half never was.

The symmetry is exact and unflattering to both of us. I read main's 926-line
HANDOFF for two days while the live one sat on a branch I was already citing by
sha. They read this port's BLOCKED.md at a copy 234 commits behind and reported a
corrected row as stale, with the live file one git show away on a ref already in
their checkout. Same gap, opposite directions, one command in both.

Their addition to the fourth connection-failure instance is the sharpest form of
it: that answer was addressed, fetchable, and cited a commit of theirs. Three
affordances and neither of us used them.

tools/port/peer-head prints, for each file this port depends on and another agent
writes, the newest commit touching it on any ref, whether this tree has it, and
the exact git show line. Report-only in check-all: being behind a peer's topic
branch is the normal state and a red line for it would be scenery within a day. It
confirms the anchored checks were already current by construction -- contract-check
reads HANDOFF and navigation.md from the newest ref rather than the working tree,
which is why my checks were right while my tree was 115 commits behind.

It caught a defect in itself on the first run. PROTOCOL.md showed mine == newest
and yet '1 unread', instructing me to git show my own version. The count was true
-- one commit touching that path is outside my ancestry -- and the label was
wrong, since two branches can each carry an unrelated commit while my copy is
still newest. A real number with a fabricated meaning, in the tool written to
close a different instance of exactly that. Staleness is now decided by whether
the newest commit is reachable from HEAD, with divergence reported separately.

The BLOCKED row about the contract is narrowed rather than closed: the merge is
still the ask, for the telling half.

The rule is not an instrument: read the peer's branch head before reporting a
defect in their file. They stated it, it would have prevented both incidents, and
the tool only makes it cost one command instead of one memory.

e30b336879 port: write the runbook P5's gate needs, and correct a misreport of a corrected row
P5's gate is 'a human clicks through it' and no document told a human how. The
commands existed in boot.gd's header and scattered through a twelve-thousand-line
DECISIONS.md, which is this project's own finding about capabilities that live
only in the record, applied to the one milestone that cannot be self-certified.

docs/port/RUNNING.md is 107 lines and every command in it was run before it was
written: build the tree, --boot --play for the cold-start walk, --menu= to skip
the 157 s intro, and a table of what a human should see at each press so the gate
is a judgement about the port rather than about whether they drove it right. It
does not claim P5 is met; it removes the excuse that the gate was hard to attempt.

Three sections exist because a reader would otherwise report the container as a
defect: what is knowingly missing (four of five destinations measured but in other
archives, each printing what it would have opened; NEW GAME's skipped chain as a
stated gap), what this container distorts (720p decodes +6.7-6.9% slow, the dummy
audio driver means you hear nothing, the exit leak line is engine-side at 8 to 8),
and how mod overrides report themselves.

The Decoder reported BLOCKED.md's 'which BGM the menu plays -- not on the disc' as
wrong and themselves as the source. The row has been struck and corrected for
days, and I am telling them rather than silently fixing a live row -- their own
asymmetry, that a wrongly-superseded row removes a live question from both views.

The correction already contains the diagnosis they have just made. It says the
negative is bounded -- the TABLES name no screen -- cites li r5 1103 and the
byte-for-byte wave match, and ends: a row here must quote the reach of a negative,
because a negative summarised without its bound reads as a bigger negative than it
is. Their message reports arriving at the same thing independently. Fourth
instance of the connection failure and the sharpest yet: the three before were an
answer sitting unread, this one was an answer sitting ADDRESSED.

Their method note inverts my own v1-to-v3 story and is the transferable part: my
'a report with a standing false positive is one nobody reads' nearly made them
filter a 40-candidate sweep. Instead they measured what the false positives were
-- guessed infrastructural nouns, 5 of 40; the real category was 'not on the disc'
used as a classification legend -- and reading those found the one that was not.
The noisy report was worth reading carefully exactly once before being made quiet.

7a7bc53893 port: a mistyped mod override was silent -- the liveness defect, in the product
Every checker fix this week was about a tool that could not tell 'I checked and it
was fine' from 'I checked nothing'. The port had the same defect facing the person
the asset tree exists for.

ExportTree.resolve announces every shadow as it happens, and its comment already
records why a startup summary was wrong. Nothing reported the opposite. Measured
with two planted overrides, one correct and one in a mistyped directory: the
correct one is announced and the typo produces NO OUTPUT AT ALL. The modder sees
the port load, run, and say nothing about the file that did nothing -- MODDING
rule 4's own failure mode, since base-and-overrides is only usable if an override
that misses says so.

ExportTree.unused_mods() and a report at run end now list them. Controlled both
directions: one inert file with the typo present, silent with it removed.

Getting the category right took three tries and that is the point. v1 'never used'
flagged data/mods/README.md on every run, and a report with a standing false
positive is one nobody reads -- precisely the failure it exists to fix. v2 'no such
path in the export' was correct and still flagged the README. v3 excludes by
extension with the rule checked rather than assumed: the export tree contains only
png, json, ogg, ogv and cmd, verified zero .md anywhere, so a .md in data/mods
could never be an override by construction.

The report also separates what v1 conflated: a file whose path exists in the export
but was not read this run is NOT listed. Every line printed is an override that
can never apply, whatever the run does.

boot.gd already had an _exit_tree and adding a second was a parse error -- the run
failed loudly instead of one hook silently replacing the other, the cheapest
possible failure mode and only because GDScript rejects it.

Their P3 delivery is taken at the strength given: Q6's count-match has disc
support for its structure -- every button record across all 16 GP_TITLE entries is
ptbtn00, ptbtn01-05, ptbtn11-13 -- but it does not show that event 3 is a
particular row, and they said not to author from it. flow.json already binds
buttons by measured screen rather than event index, so nothing changes. Their own
negative is narrower than 'not found': the DIFFICULTY search assumed four items
pair with f variants, so what is established is 'not an 8-record btn-named build
anywhere'.

3a048de536 port: every one of my checkers passed on an empty input
The Decoder generalised my empty-band case into the rule I now keep: a control
that only compares two things cannot tell you the comparison is happening. An
empty band list, a blank frame, an empty register -- each makes a checker
agreeable rather than wrong, and agreeable is indistinguishable from correct in a
log.

Swept my tools against inputs containing nothing. audit-kinds exited 0 on a tree
with no authored/*.json, having printed '0 kind label(s)' and reported clean.
verify-transcode-fidelity would call every transcode faithful with no videos in
the manifest, having compared none. check-claims exited 1 from a FileNotFoundError
inside the withdrawal hook -- which in that script's own vocabulary means 'a
refuted claim is still being asserted', so a wrong directory got diagnosed as a
dirty corpus. A real failure with a fabricated reason, the third instance of that
family after my control anchoring at the wrong document.

All three now exit 2, check-claims via a preflight that names the roots it needs.
Both self-tests gained the liveness case driven as subprocesses: audit-kinds
--selftest runs itself in an empty directory and requires 2, and check-claims
--control is now six cases -- clean 0, unmarked 1, marked 0, outside-root 0, empty
register 2, nothing to scan 2.

What makes this worth an iteration rather than tidying: none of these tools was
ever wrong on real input. What none of them could do was tell 'I checked and it
was fine' from 'I checked nothing', and every green line I have quoted was the
first of those only because the directory happened to be right.

Also recorded: their ring_row.py used 'main_menu_item(ring_row(f)) is not None' as
a main-menu test, and a TITLE frame passes it -- the gutter carries a bright
cluster at y=243 inside tolerance of row 0. No result they sent me is affected,
for a structural reason rather than a lucky one: (B) from a submenu goes to the
menu, never the title, so the weak test was never shown the frame that breaks it.
I have not re-derived their focus results and am not treating this as a reason to;
what I have is their statement of the exposure and the structural argument,
recorded as that rather than as verification.

Every asserting check passes, 14 of them.

The reset question is settled and it went the way that makes the restraint
correct: a submenu resets to its OWN OPENING ITEM, a per-screen default that need
not be the first. DIFFICULTY opens on NORMAL, second of four, and returns to
NORMAL after a confirmed DOWN and a round trip. So ptbtn11 is right for a reason
rather than by coincidence, and buttons[0]-is-a-repair is measured rather than
principled. contract-check gains check_reset_target, whose teeth the code bounds
honestly: on EXTRAS the named item happens to be first, so agreement is not
evidence -- what it guards is a future refactor silently substituting an index.

Their refutation attempt on extras/initial_focus was made against the disc rather
than against their agreement, and it survives: ptbtn11 y282 against 362 and 442.
Re-checked from this port's own export, a different reader of the same disc, and
the numbers are identical -- extras 282/362/442, main menu 162/242/322/401/482.
Which also confirms EXTRAS could never have separated named-item from top-item.

Menu focus does not survive a reboot: six fresh boots opened on NEW GAME, three of
them following sessions that ended on EXTRAS or OPTIONS. So the authored value is
a fresh-start value. The reach is carried verbatim into the why -- every session
ended with the emulator KILLED, so this measures 'does not survive a killed
session', and a console that remembers across a clean power cycle would not
contradict it.

Still open and not leaned on: whether the reset target moves once a difficulty has
been confirmed; the same SELECT DATA crash prevents testing it.

55d30209d9 port: the counter-example I kept asking for was in a file I wrote
For several iterations I said the MISSION-SELECT-versus-top-item ambiguity needed
a screen whose opening item is not its first, and that none was known. The Decoder
found one and reported it had been sitting unconnected in their corpus.

It is in mine too, and I authored it. authored/flow.json under
main_menu/buttons/ptbtn01 has read since 1defbe0 on 2026-08-29: 'MEASURED
destination (EASY/NORMAL/HARD/BACK, opening on NORMAL, then SELECT DATA)'.
DIFFICULTY opens on the second of four. So 'a screen opens on its first item' is
refuted as a general description of this game, and on EXTRAS, TUTORIAL and OPTIONS
the named item and the top item coincide by accident.

Worse than an index failing to amplify: my extras/initial_focus_why framed the
ambiguity as conditional -- 'it matters IF another screen is ever authored' -- in
the same file that already recorded such a screen. Future tense over a fact twelve
keys away. Corrected to name DIFFICULTY concretely.

MenuFlow.initial_focus's buttons[0] fallback is now documented as a repair for
broken data rather than a default, and that is measured rather than fastidious: if
a screen reaches that line silently the port shows a top-item default for a game
that does not always have one. No authored value moves -- DIFFICULTY is not a
GP_TITLE build and EXTRAS keeps ptbtn11, correct under either reading. Walk re-run
unchanged.

It does not settle the question, which is about reset rather than opening. That
needs the cursor moved inside DIFFICULTY, left and re-entered, and its forward
path crashes the guest at SELECT DATA so the run must go back rather than on.

No checker either of us has built would have caught this. Every instrument here
verifies that a claim matches a value; nothing detects that an answer already
written down is not being connected to the question it answers -- and mine had
both halves in one file.

It also makes the previous iteration's restraint look better: declining to promote
'4/4 submenus reset' to a rule was argued from the principle that a generalisation
should not pre-decide the next screen, and the next screen turns out to be one the
generalisation would have got wrong.

7ebf5fc8c5 port: assert the scan boundary I had hand-verified, and give audit-kinds a self-test
check-claims --control plants a revival in docs/port/ and requires exit 1. That
the plant lands INSIDE a scanned directory was a property I checked manually, one
time, and wrote up -- the exact pattern I had criticised in this same tool one
iteration earlier. A fifth case now plants the identical text OUTSIDE the scanned
root and requires 0, so the pair asserts the boundary is real: same text, 1 inside
and 0 outside. Either half alone is consistent with the tool scanning everything,
or nothing. Five cases: clean 0, unmarked 1, marked 0, outside-root 0, empty
register 2.

audit-kinds has always reported what it found and was never asked whether it can
find anything, while its clean runs are cited as evidence that fifteen labels are
grounded. --selftest pushes three synthetic rows through the real classifier and
reads its verdict: citing nothing must read BARE, a real path ok, a missing path
DANGLING. Verified two-directionally -- an extractor stubbed to accept everything
returns exit 2. Asserting in check-all.

All four submenus are now measured to reset -- LOAD GAME, TUTORIAL and OPTIONS
joining EXTRAS -- and the main menu remains the only screen that remembers. Three
of the four are not in this export, so no authored value changes.

NOT promoted to a rule, deliberately. 'Submenus reset' at 4/4 is better evidence
than the 2/2 that made wrap a menu-wide rule, and adopting it would change nothing
today because the only submenu this port ships is already measured. What it would
do is pre-decide the next screen from a generalisation instead of a measurement --
the trap that nearly let a derived rule overwrite EXTRAS' measured opening item.
The guard prints the 4/4 finding beside its per-screen values so the evidence is
visible without being load-bearing.

MISSION-SELECT-versus-top-item stays open: none of the three separates it, each
opens on its own first item, and NEW GAME is untested.

Remaining without a harness self-test: verify-transcode-fidelity. Every asserting
check passes, 13 of them.

575e287526 port: the register check had no executable control, and an empty register passed forever
check-claims guards the refuted register, the thing both agents lean on when they
say a dead claim is not being re-asserted, and it had no control machinery at all.
Every 'planted a revival, it failed, removed it, it passed' in DECISIONS was done
by hand, once, and never again -- in a repository where two of my own tools carry
the line 'a control that does not execute is not a control'. I wrote that about
somebody else's tool.

The hole the Decoder found in their equivalent was here too. The scan loop runs
once per register row; with no rows it runs zero times, fail stays 0, and the
script printed 'every refuted claim appears only inside its correction' and exited
0. A register that parses nothing reported clean forever -- the stub defect, in
the checker whose clean runs both of us cite. It now exits 2 with 'the harness is
broken, not the corpus'.

--control executes four cases, each driving this script as a subprocess and
reading its real exit code: clean 0, unmarked revival 1, marked revival 0 with no
false positive, empty register 2. Asserting in check-all.

Two things taken from their build of the same thing rather than invented: the
self-test drives the real machinery and reads its actual exit code -- my first
--selftest reasoned about what the harness would do, which is the cheaper mistake
and the one I made -- and the three-way exit convention, which is what lets 'the
corpus is dirty' and 'the checker is broken' be different answers instead of both
being nonzero.

The plant lands in a real scanned directory, because a control that runs somewhere
the tool does not look proves nothing about the tool. Verified two-directionally:
pointing the plant at an unscanned path makes the control report itself broken.

Still without harness self-tests and filed rather than left looking finished:
audit-kinds and verify-transcode-fidelity.

Every asserting check passes.

14c3bad7ad port: the control harness now asserts itself, and it caught me twice doing it
The gap I named and the Decoder prioritised: every --control run asserts that each
check fails on a perturbed contract, and none asserted that a broken control
reports broken. That is printing a verdict without asserting it, one level up. A
harness that silently approves a dead check is exactly as useless as a check that
silently approves a dead value.

contract-check --selftest feeds the machinery a stub that cannot fail -- a
function that prints 'everything is fine' and asserts nothing, which is precisely
the defect I shipped in verify-transcode-fidelity's unconditional return 0 -- and
requires the machinery to flag it. Exit codes follow the Decoder's convention: 0
all good, 1 a real check failed, 2 the HARNESS is broken and nothing it reported
can be trusted. Asserting in check-all.

It caught two defects while being written. The first version checked that the stub
left the failure counter at zero and then REASONED that control() would therefore
flag it -- arguing where a measurement was available, the error this whole thread
has been about, committed inside the tool built to prevent it. Rewritten to push
the stub through the real control() loop and read its verdict. It then returned 2
immediately: the stub was flagged, but as 'the control's own anchor is gone'
rather than as a dead check, because the src selection anchored anything not in
one specific list at the walk document instead of HANDOFF. A real failure for a
fabricated reason, which is the confusion ANCHOR SPLIT exists to separate.

Not covered and filed rather than left looking finished: check-claims, audit-kinds
and verify-transcode-fidelity have controls and no harness self-test. The shape is
known and the fix is cheap.

Every asserting check passes.

e5189a1328 port: retract the S00A coverage hole -- it was my control's filter, not the check
Yesterday I reported that a 6 kHz-lowpassed S00A deviated only 1.28 dB, so a
transcode that lost its top end would pass the band check, filed it as a coverage
hole and sent it to the Decoder, who wrote back that it was the part of my message
they would keep.

It is wrong. lowpass=f=6000 is SINGLE-POLE, 6 dB/octave -- a mild tilt that leaves
most of the octave above 6 kHz in place. I named it 'a transcode that lost its top
end' and it did not build that failure. With a real 4-pole brick wall the loss is
caught: ADV 6.52 dB at 4.3x, S00A 1.83 dB at 1.2x. Covered, not absent.

The instrument took the blame for the control's weakness, one day after I told the
Decoder that a control must be a hard negative. The harder rule: a control must
CONSTRUCT the failure it is named after. Mine carried the right name over the
wrong filter and I read the resulting miss as a property of the check.

What survives is weaker and more precise than either version: S00A's margin is
1.2x, which is thin, and the tool now prints a THIN warning below 2x. The margin
depends on how much HF the material has, which is a real sensitivity statement.

The retraction had to travel fast because the other agent had already adopted the
finding. A wrong result the other agent has taken up is more expensive than one
they ignored -- an argument for sending corrections at the same priority as
findings.

Also recorded: they tested 'an asserting step that asserts nothing' against their
own tools and both had it, including one written the same day they read my report
of the shape. Their statement of it is better than mine -- a check has two failure
modes and the loud one hides the quiet one; printing a verdict is not asserting
it. And they controlled the exit code in BOTH directions, clean 0, planted revival
1, control passing 0, control deliberately broken 2. My --control flags assert
failure-on-perturbation but not that a broken control reports broken, which is the
same gap one level up. Next thing to close here.

9405d71aae port: a hard negative found a coverage hole and two defects hiding each other
The Decoder generalised my identity rule back at me -- a positive control that is
merely 'high' hides the difference between an exact instrument and a lossy one --
and it landed on the band check I shipped yesterday. Its positive control was 0.29
and 0.66 dB, and small is not zero. Source against itself read 7.656 dB, larger
than the number the check calls faithful: bands() applied the fold to one side
only, correct for source-versus-transcode and wrong for source-versus-itself. The
fold is per-side now and identity reads 0.000 dB exactly. The published 0.66 stands
unchanged; what changed is that the instrument is known unbiased rather than
assumed to be, and the scale's bottom is anchored.

Same rule applied to the port's headline numbers: the image RMSE metric reads
0.0000 for a capture against itself and after a PNG round-trip, so 13.21 is real
difference and not pipeline noise. verify-capture now asserts that before printing
any row and refuses if it is not exact.

Then their refutation attempt on 'band energies need no alignment'. It survives --
1 s of misalignment costs 0.16 dB -- but 10 s costs 1.00 dB, so the claim is
narrowed to robust, not free. Their real point: separation is material-dependent,
two unrelated music banks separate by 5.28 dB where an unrelated movie gave me
19-20. A movie is an easy negative, so I built the hard one and it failed. A 6 kHz
lowpass is caught on ADV at 4.27 dB, 2.8x, and NOT caught on S00A at 1.28 dB
against a 1.5 dB threshold, because S00A's own 6-16 kHz content sits at -67 dB. A
transcode that lost its whole top end would pass on S00A. Reported per asset as
COVERED / NOT COVERED rather than asserted, and tracked in BLOCKED.

Splitting the top band raised ADV from 2.58 to 4.27 dB. That is changing the
instrument's resolution so it can see a failure it must see, driven by a control
it failed -- the pass threshold is unchanged.

Repairing it exposed two defects that had been hiding each other. return 0 was
unconditional: making the difference path report-only swallowed the band verdict,
so check-all's transcode-bands must-pass step could not fail -- an asserting step
that asserts nothing, shipped by me one day after writing up the same shape in
someone else's work. And the disqualified difference path was still voting on the
exit code, so fixing the return turned the run red for the wrong reason. Neither
would have surfaced without a control the tool could fail.

66fb49dba3 port: the difference path is disqualified, and the identity test is what showed it
Audited my own docs for the Decoder's method-versus-subject error -- a negative
about the instrument written as a negative about the subject. Clean: every
impossibility claim in DECISIONS is already method-scoped ('undecodable WITH
REACH', 'cannot be answered BY LISTENING'), and both live open rows in BLOCKED
read 'not observed' and 'deliberately not inferred'. Nothing to fix, recorded as a
negative.

Then three cheap measurements located the fidelity fault exactly. Identity --
source against a second decode of itself at lag 0 -- subtracts to -inf, so
decode-and-subtract is exact and the pipeline was never the problem. A LOSSLESS
flac of the identical fold reaches only 14.2 dB down, searched exhaustively at
stride 1 over 300 lags, where it must reach about 90. The shipped transcode's 8.73
dB is therefore meaningless.

So the difference path is disqualified rather than inconclusive, and every number
it produced in this thread -- including the 'difference louder than source'
readings I reported twice -- was an artefact of the lag search, not evidence about
a transcode. The tool now refuses on that path and carries its acceptance test in
the code: make lossless-vs-source return >= 60 dB down before believing anything
it says.

The identity test costs one decode and no encoder, and it should have been the
first thing run three iterations ago. Before asking whether an instrument can
measure a difference, ask whether it returns zero for no difference.

Hypotheses ruled out and recorded so nobody re-runs them: drift (offset stable at
about -2465 samples across t=2, 10 and 20 s), container start time (start_time is
exactly 0), the codec being perceptual (the lossless control fails the same way),
and level or content mismatch (bands agree to 0.66 dB).

P4's waveform question is now open with a disqualified instrument -- worse than it
looked yesterday, and better than believing 8.73 dB meant something. The band
check is unaffected and still asserts.

de25787d84 port: a capital letter hid a refuted claim; and band levels answer what alignment could not
Three findings, two of them defects in my own checkers.

Changing the KIND of quantity answered the P4 fidelity question on the first
attempt. Four attempts at sample-exact difference-signal alignment produced four
failures and no verdict -- well past the Decoder's rule that two failed attempts
at the same measurement are evidence the quantity is wrong, not the parsing. Band
energies need no alignment at all: both transcodes match their sources to 0.66 dB
worst-case across four bands, while an unrelated movie lands at 19-20 dB. Two
populations an order of magnitude apart, so the 1.5 dB tolerance sits between
measured values rather than being picked. Asserting in check-all with the known
negative on every run, not behind a flag. It also diagnoses the failure it
replaced: matching spectra mean same content at same level, so the difference
signal's failure is my alignment, now by evidence rather than assumption. The
difference path stays report-only. Band agreement cannot tell a faithful
transcode from one that kept the spectrum and mangled the waveform -- weaker than
P4 wanted, and what I can support.

check-claims held 'no loop-point field has been identified' in its register the
whole time and matched case-sensitively, so a capital N at the start of a sentence
hid a registered dead claim in BLOCKED.md -- the one document whose job is to say
what is still open. The correction had reached authored/audio.json and not the
blocked list, which is exactly the failure that file's own why warns about.
Matching is case-insensitive now and immediately surfaced five more unmarked
sites, including a whole DECISIONS section still describing the refuted state. All
six fixed: four tokened, two rewritten with the shipped values. Controlled with a
planted capitalised revival.

And --control caught its own harness: it perturbed only the first occurrence of an
anchor, and the Decoder's delivery heading now appears twice, so the check read the
untouched duplicate and passed a wrong contract. A perturbation that does not
reach every copy makes a check untestable silently. First time a control has
failed because of a change in someone else's document rather than my code.

Not accepted from the same message: the (A)-skips-a-movie row is NOT stale. It
reads (a) ANSWERED, cites Q9, and points at flow.json's skippable: true. Reported
back rather than quietly 'fixed' -- marking a live row stale is the error their
own message is about.

Every asserting check passes.

c7ebab1624 port: attempt the P4 fidelity question -- four traps reproduced, no verdict claimed
AUDIO-VERIFICATION.md section 1 calls transcode fidelity the question P4 actually
raised, needing neither an engine nor a device, and gives it in four lines of
shell. Nothing implemented it: verify-video-audio deliberately declines, saying a
difference RMS without alignment is meaningless. So the P4/P7 gate has rested on
level and non-silence and the fidelity claim has never been made.

tools/port/verify-transcode-fidelity now exists and is committed WITHOUT a
verdict, deliberately.

Four ways the measurement lies, each reproduced here rather than reasoned about.
Indexing with a negative lag wraps to the end of the array in Python, so the
difference was the transcode subtracted from an unrelated part of the source --
reported 7 dB LOUDER than the source, the same catastrophic-looking number the
doc warns of. My regex for the recorded -af truncated the fold to its FL half,
folding the source to a left-only signal: the doc names that trap, I reached it
through a parsing bug, and the matrix contains runs of spaces so it cannot be
tokenised on whitespace. -ss before -i is a container-level jump and on this WMA
Pro source returned 4.6 s for a 4.0 s request while the Ogg side returned 4.0 s,
so the windows covered different stretches of the movie, best correlation 0.172 --
this one is NOT in the doc and is indistinguishable from the alignment trap that
is. And the single-resolution search returned +2413 against a window of +-2400,
its own boundary rather than a peak, the same family as the Decoder's period
estimator returning its search floor.

Why no verdict: best alignment is corr 0.763 on S00A and 0.075 on ADV, and both
still report the difference louder than the source, which cannot be true of two
aligned signals at equal level. The remaining fault is on my side. A tool printing
'not faithful' in that state would put a false defect on the exporter. It now
distinguishes 'could not align' from 'not faithful', two failures I conflated
twice before separating them.

Filed for the human as a proposal, not an edit: section 1 should carry the
imprecise-seek trap as a fourth entry.

13bc0b02f7 port: make the frame count permanent, then correct what I read from it twice
The Decoder's closing point -- the inference is cheap and the measurement looks
expensive right up until someone does it -- is actionable, so the probe I
reverted is now permanent. The exporter records each transcode's duration and
frame rate in the manifest (probed from the file it wrote, not the source), and
every video run prints what it showed against what the media holds. An instrument
that has to be added before the question can be asked will not be there the next
time somebody reasons instead.

Then the instrument corrected me twice more.

It is an UPPER BOUND, not a count. It counts engine frames, and the engine renders
the UI at its own rate: on a quiet box ADV drew 6480 frames across a 4123-frame
video, 44 fps against the media's 30. Above that crossover it constrains nothing,
and '157% presented' is the counter used outside its range. The report now says so
instead of printing a percentage.

So 'the player skips, heavily' is not supported. At 8.3 engine fps under
contention S00A could not have shown more than 28% -- a valid bound under
contention and nothing more. Quiet, the bound is 88-90%, permitting anything from
no drops to a tenth.

And the 720p-versus-432p contrast is refuted -- the finding I sent them twice. I
reported ADV +6.7% against S00A -0.5% and built 'heavy decode falls behind, light
keeps up' on it. Quiet, both run +6.7...+6.9%. The -0.5% was a contended run in
which the player dropped frames to hold schedule. I was measuring which run
happened to share the box and reading it as a property of the resolution.

What survives is sturdier than either: playback runs +6.7%...+6.9% long on this
container, five runs, both videos, quiet, resolution-independent.

Three corrections in three iterations, all mine, all the same shape: argued from
an absence; measured and over-read; then found the measurement was taken under a
confound I introduced myself by running the suite alongside it. Their rule needs a
companion -- ask what the quantity can be skipped by, and ask what else was
running.

bb3f59459c port: I measured my own claim and it is wrong -- the player skips, heavily
I told the Decoder that a player running long decoded everything, so my video
spans were time-to-consume measurements. They granted it and added the refinement
I had not claimed: running long proves the player did not skip ENOUGH to stay on
schedule, not that it skipped nothing.

That is testable, because a video player cannot present more video frames than
the engine draws. Engine.get_frames_drawn() across each playback: S00A drew 775
frames in 93.33 s, 8.3 fps, 28% of the 2813 frames in the media; ADV drew 1941 in
140.77 s, 13.8 fps, 47% of 4123. Both skip most of their frames, and S00A kept
real time BECAUSE it dropped roughly three frames in four -- the exact mechanism I
claimed was absent. The sentence was not unproven, it was false, and the probe
that refutes it is four lines long and could have been written the day I wrote the
claim.

The probe's honest limit, stated because it cuts the other way: it counts
PRESENTED frames, not decoded ones. Theora is inter-frame predicted, so a decoder
generally must decode frames it never displays. This refutes 'presented every
frame' and leaves 'decoded every frame' unmeasured, and I have no instrument for
the second. Their read_offset counter is a consumption counter precisely because
it cannot have that gap.

And the number I sent them twice is a spread. Three ADV runs: 146.42, 146.60,
140.77 s, giving +6.5%, +6.7%, +2.4%. I quoted +6.7% as the measurement; it is the
top of a range whose spread is nearly as large as the effect on the third run, and
the runs differed in what else the port was doing. Reported as +2.4%...+6.7%, n=3,
load-dependent, from here.

What survives is the qualitative result they cared about: heavy decode falls
behind the container clock and light decode does not, demonstrated in one box --
now correctly stated as a lower bound on a deficit measured under skipping.

The general form, third time in this project: I argued from an absence -- no
overrun would be visible if frames were dropped -- instead of measuring directly.
The direct measurement cost four lines. An argument that a mechanism is absent is
not a measurement that it is absent, and I had just told the Decoder that being
right by luck is not evidence.

Also recorded: their sweep for stale HANDOFF sections is a negative, 7 candidates
and 0 real, because in that corpus a red heading marks a correction being
delivered far more often than a section overtaken. Neither of us should build it.

74321f0794 port: a leak that was not mine, a second narrow anchor, and a result recovered
Three findings, one of them a withdrawal of my own fix.

The ObjectDB leak line on every run is engine-side. The leaked objects are the
Ogg streams and playbacks of exactly the cues that sounded, which reads as
MenuAudio holding references past teardown. It does not: releasing every
reference the port owns -- stop each player, null every stream, clear _players,
clear cues/beds/voices -- moved the count not at all, 8 before and 8 after, with
a debug print confirming _exit_tree runs. The cleanup is REVERTED rather than
kept, because code that changes nothing under a comment claiming to fix a leak is
worse than none: the next reader sees it handled and stops looking. Filed as a
negative result so nobody re-investigates.

check_focus_persists gets a SECOND NARROW ANCHOR, repairing a weakness I recorded
last iteration and did not act on. It anchored on the heading -- the conclusion --
so when the Decoder corrected the run's item names it sailed past, surviving by
luck rather than design. It now also rests on the evidence, the ring at y 384.0
before the round trip and 385.5 after, which is the geometry-free equality the
conclusion stands on. The two anchors are checked AGAINST EACH OTHER: if one
matches and the other does not it reports ANCHOR SPLIT. The second anchor has its
own known negative, perturbing only the evidence line -- without that it would be
decorative and the check would still rest on the conclusion alone.

And their skippability rule recovers a result I had over-withdrawn. Frames can be
skipped, bytes consumed cannot; that is why my withdrawal reaches my test and not
their read-offset one. Applied backwards: the OVERRUN IS the evidence nothing was
skipped. A player that drops frames finishes on schedule; mine took 146.6 s for
137.44 s of media, so ADV +6.7% and S00A -0.5% are time-to-consume measurements
after all. The withdrawal stands for the pacing-audit use; the load-starvation
result is recovered. Standing caveat recorded: every timing this port publishes is
frame-derived, and the only reason those seconds mean anything is that this player
demonstrably does not skip -- an empirical property, not a guarantee, and nothing
checks it.

Reported: the 'do not hardcode the menu's initial focus' HANDOFF section still
reads as live while two later sections have overtaken both its claims.

Every asserting check passes; 14 controls fire.

07a64648a6 port: my media-versus-wall-clock method cannot audit container pacing
The Decoder proposed borrowing it to settle their 27.6 fps confound. It does not
work, and the reason matters more than the result. Three S00A replicates, whose
93.78 s is fixed by its own sample rate: -0.44%, -0.51%, -0.50%. Tight,
reproducible, and unable to answer the question it was asked. The video player is
driven by the container clock -- it picks frames from elapsed time as that clock
reports it -- so a uniformly slow clock would present fewer frames per real
second and still finish in exactly 93.78 s of container time. A perfect match,
produced by the failure it was meant to detect. Every timer inside shares that
clock, the shell's date included.

My earlier entry conflated two uses. 'Compare through media length, not wall
clock' is sound as a COMMON UNIT between their numbers and mine, because media
length is container-independent. It is not an AUDIT of pacing. Corrected here and
in BLOCKED rather than in place.

What the contrast does establish favours their doubt. Same container, same clock,
same player: ADV at 1280x720 runs +6.7% over its media, S00A at 768x432 runs
-0.5%. Load-dependent starvation is demonstrated positively, not inferred, and
Xenia is far heavier than 720p Theora while their frame counts are taken per
container-second -- the exact axis this acts on.

What would settle theirs is a clock the guest does not control: frames presented
per audio sample consumed, since audio hardware consumes at a fixed rate. Offered
as a route, theirs to say whether Xenia exposes it.

Their addendum to global-versus-narrow is written into contract-check's header:
they did not loosen an instrument gradually, they swapped it wholesale the moment
it failed and the swap felt like rigour. So when an ANCHOR LOST comes, add a
second narrow anchor rather than one looser one.

cf3a9a0454 port: running it as a player finds two defects reading it did not
--boot --script= parsed, was stored, and did nothing. The script only starts at
_menu_enter, and a --boot run without --play never enters a menu -- it holds on
the title and quits. The run completed, exit 0, no menu line, no press: a clean
result to a question never asked. This file already warns about that exact shape
600 lines above the bug, where --capture used to photograph the first frame of a
scripted run. The warning was written, kept, and did not stop the same class
recurring in the neighbouring flag. Now push_errors and exits 2, naming both
working forms, refusing rather than implying --play since the two runs differ by
157 s of intro. Verified: --boot --play --script walks power-on through splashes,
ADV, title, (A), main menu, down, (A).

A comment above audio.play_bed described the port as CHOOSING the menu track,
which HANDOFF Q10 refuted a week ago -- BGM_103 is measured on three independent
legs and audio.json says so. Third instance of the drifted-comment trap. The dead
phrase is now a check-claims register row, controlled: a planted revival fails and
removing it passes.

And the boot's wall-clock seconds are a property of this container. ADV takes
146.6 s of wall clock for 137.44 s of media, +6.7%, while S00A runs real time at
-0.4%. Not a post-roll and not a general deficit: ADV is 1280x720 and S00A is
768x432, this box has no GPU, and 720p Theora decodes below real time here. The
transcode is faithful against a 137.71 s source and the exporter does not rescale.
P3/P7 artifacts quote seconds containing that deficit -- reproducible here, not a
statement about the port or the game. Comparisons with the Decoder's measurements
must go through media length, not wall clock; they carry an explicit emulator
pacing factor for the same reason and I had been quoting mine as exact.

Their negative result on LOAD GAME, TUTORIAL and OPTIONS leaves guard_focus_scope
right to count them UNMEASURED rather than 'resets'. The transferable part is
their instrument story: a narrow calibrated reader failed, so they generalised to
a whole-frame comparison, which died the moment a crash dialog overlaid the frame
while the narrow reader kept working. contract-check is deliberately narrow,
individually anchored checks for the same reason, and the temptation after an
ANCHOR LOST will be to loosen the matching -- trading a failure I can see for one
I cannot.

Every asserting check passes.

3ddd298262 port: EXTRAS resets, measured -- and being right by luck is not evidence
Ring at 347.5 on entry (MISSION SELECT), 427.5 after one delivery-confirmed DOWN,
347.5 on re-entry with the frame 0.0% different from first entry, screen
confirmed by eye because an earlier run was fooled about which screen it was on.

Two things settle here. The caveat on extras/initial_focus comes off: MISSION
SELECT is a genuine initial focus, because a screen that RESETS cannot have a
single-entry reading that is measuring history -- that objection was live only
while persistence here was unknown. And focus_persists: false for extras is now
written explicitly with kind: measured. Nothing changes at runtime, since the
port already defaulted to false; the point is that an absent key and a measured
false behave identically and mean opposite things -- 'nobody looked' versus 'the
game was watched doing it' -- and only the second is visible to audit-kinds.

It does not vindicate how it got there and is not recorded as if it did. For one
iteration contract-check ASSERTED extras non-persistence with nothing behind it,
the Decoder flagged it, and the measurement then agreed. Their separation is
sharper than my own account was: declining to generalise the memory was correct,
on the evidence then and on measurement now, since the two screens genuinely
disagree -- but encoding 'not measured here' as a positive assertion of the
negative was a different move that happened to land. Being right by luck does not
retroactively make it evidence. The check is rewritten to rest on the
measurement rather than left in place looking vindicated.

guard_focus_scope no longer polices 'only main_menu': there is no menu-wide rule
to state, since two measured screens disagree. It now states both measured values
and counts the screens that say nothing, printing UNMEASURED, not 'resets'.

Untested and not built on: OPTIONS, LOAD GAME, TUTORIAL. And nobody can separate
'resets to MISSION SELECT' from 'resets to the top item' -- they coincide, since
ptbtn11 is both. The port's value is right under either reading and the reason is
not established, which matters the day a screen is authored whose opening item is
not its first.

16 kind labels audited clean, 14 controls firing, every asserting check passes.
The P5 walk artifact now matches a measurement on both halves rather than one
measurement and one default.

73710ac2e3 port: an authored value becomes measured, and a difference-only check gets an origin
The Decoder corrected their own focus delivery: the persistence run's item names
were two positions out, from a reader using design-space rows against captures
carrying Xenia's chrome and a 1.060 scale. Two things follow.

initial_focus_kind moves from authored to measured. NEW GAME on a fresh boot, 2/2
fresh boots, both the first menu entry. The value did not change; its standing
did, and the upgrade is not because the measurement agrees with me -- they had
said my agreeing with their records was no evidence, which was correct, and this
is a direct reading independent of the reasoning that chose NEW GAME here. "First
entry" is load-bearing: since the menu remembers its cursor, a reading taken
later measures history, which is the objection that voided the earlier
TUTORIAL-versus-NEW-GAME disagreement. The superseded reasoning is kept under
(was) lines -- the field existing and being labelled honestly is what made
arriving at a measurement a label change rather than an archaeology problem, the
third time that has paid off after loop_start_s and the +0x08 read.

My check_focus_persists anchor survived a correction it should not have been able
to detect. It anchors on the heading, the conclusion, not on the item names. That
is lucky rather than designed: the conclusion is geometry-free -- ring at y 384.0
before the round trip and 385.5 after, an equality immune to a constant offset --
while the names were not. The check would not have caught the label error, and
nothing in it distinguishes anchored-on-a-robust-claim from anchored-above-the-
part-that-was-wrong.

Their generalisation: a control that only checks differences is blind to the
origin. check_splash_dwell is that shape -- it compares the widest gap between
keyframe times, and a reader with every time shifted by a constant passes. Added
check_splash_times, asserting the absolute list the contract prints. Origin and
difference now fail independently.

Writing that control reproduced the error one level down: its perturbation
literal was written from memory of the prose, with a space where the document has
a newline, so it reported its own anchor gone. A control written from a memory of
the source rather than from the source is the class of error these checks exist
to catch. Thirteen controls, all firing.

Q2 closed: fixed same day, and the row was worse than I reported -- the splashes
were also mis-paired as 10/11, one half each of two different pairs.

EXTRAS remains unmeasured; the run meant to settle it navigated to OPTIONS
believing it was EXTRAS. Every asserting check passes.

bb0b2dfe7e port: correct three words the shell ate from the previous commit message
The message of the commit before this one lost three backticked words to command
substitution: it should read "what each `kind` in authored/ rests on", "had no
`why` of their own", and "fell back to the parent's `why`". The sentences still
parse, which is why it was not obvious -- a dropped noun leaves grammar intact.

Not amended: that commit is pushed, and rewriting published history on a shared
remote is forbidden regardless of how small the fix is. A correction that costs
one empty commit is cheaper than a rule bent once.

Cause: the message was passed to `git commit -m` inside a double-quoted shell
string, so every backtick pair ran as a command. Fixed by writing commit messages
to a file and using `-F`, which is also why this one is intact.

7c2a47f8be port: audit every kind label, and seven rested on a neighbour's argument
tools/port/audit-kinds reports what each  in authored/ rests on. Nothing
had ever checked them, which is the point -- the disciplines that fail this way
are the ones that never visibly failed.

Seven of fifteen labels, every goto_name_kind, had no  of their own. Four
scored ok on the first run because the audit fell back to the parent's ,
which argues the DESTINATION while the label is about where the NAME came from.
That is the same error I was corrected for the previous iteration, one level
down: crediting a claim with evidence that does not bear on it. Borrowed evidence
is now its own outcome, and all seven carry a why citing HANDOFF Q4's own words
and stating that the port never branches on the field.

The audit refuted itself twice first. It counted only paths, shas and filenames
as citations, so HANDOFF Q1 and PORT-MISSION section 7 read as citing nothing --
four false positives, and an audit that invents defects is worse than none
because its false positives are indistinguishable from its true ones until each
is opened. It also resolved paths against committed refs only, failing on a
citation to the tool being written. Both fixed. It still cannot read a cited page
to confirm it says what the why claims, and prints that every run.

MEASURED and measured both existed; a consumer comparing == measured misses the
other, and a label that fails to match reads as ABSENT rather than wrong.
Normalised.

Refutation attempt on HANDOFF Q2's map of GP_TITLE. The headline survives and is
exactly right: 4 UI states + 2 loading variants + 2 boot splashes = 8 states
shipped twice = the 16 entries the archive holds, confirmed against my export's
entry map. But the row enumerates six of those eight -- entries 10, 11, 13 and 14,
publisher_logo and developer_logos, appear nowhere in it. A reader counting Q2
gets twelve, and this is the row already corrected once for an ordinal-versus-
entry error, which is the mistake four unlisted entries feed. The port is
unaffected; both splashes are exported, named and verified at RMSE 2.17 and 3.05.

Every asserting check passes, audit-kinds included.

f1e249a606 port: correct a check that asserted an absence of measurement as a finding
The pair I shipped this iteration -- focus_persists on for main_menu, off
everywhere else -- reported both halves as agreement with the contract. Nothing
measured that extras does not persist. The corpus has EXTRAS' opening item from
one entry and (B) restoring the PARENT's focus 4/4; neither says what a submenu's
own cursor does on re-entry. Caught by the Decoder.

It is the mirror of the trap it was written to avoid. I refused to let a derived
menu-wide rule overwrite a measured value, then let 'not measured here' become a
positive assertion of the negative. Both treat a gap in the corpus as if it
carried information and differ only in which direction they fill it. And the
failure mode was the bad one: if the game does persist EXTRAS, the check holds
the port to the wrong behaviour and passes while doing it.

check_focus_persists now asserts only the measured half. The scope became a
separate guard with its own outcome word -- 'only main_menu, AUTHORED DEFAULT,
unmeasured elsewhere' -- which still fails if widened, since that should be a
deliberate edit, but can no longer be read as the game being known to reset.
focus_persists_why records the correction rather than being rewritten.

It also weakens a label. EXTRAS' initial_focus is marked measured and was taken
on a single entry; now that the main menu is known to remember its cursor, a
one-entry reading of any screen may be measuring history rather than what the
screen opens on -- the same objection that reframed the TUTORIAL/NEW GAME
disagreement. The observation stands, its reading as an initial focus does not.
Caveat attached, kind left as measured with a note that it changes if EXTRAS
turns out to persist.

Not building on the non-persistence half until their EXTRAS re-entry run returns.

23dda95643 port: the main menu remembers its cursor -- a measured P5 defect, fixed and scoped
Measured by the Decoder today: (B) from the menu to the title and (A) back
returns to the item you left, not to a default; their control passed first, two
delivery-confirmed DOWNs moving the cursor exactly two items before the round
trip. The port reset to initial_focus on every entry, so a player who moved to
EXTRAS, pressed (B) then (A) landed back on NEW GAME. MenuFlow.enter() now
consults opening_focus(), and a new set_focus() writes the memory.

set_focus() exists because two call sites set focus -- a cursor move and (B)'s
restore -- and a memory updated at only one of them is right until the player
uses the other.

focus_persists is true on main_menu and nowhere else, and the scope is the
authored part. wrap generalised because it was measured on two screens; this was
measured on one. Here that is stronger than a preference: extras opens on MISSION
SELECT as a MEASURED initial focus, so a menu-wide memory would have silently
replaced a measured value with a derived one.

Both halves are in one artifact, because a one-sided test passes a port that
quietly generalised: the menu returns to ptbtn05 after the round trip, and extras
opens on ptbtn11 both times despite being left on ptbtn12. contract-check asserts
the pair -- on where measured, off elsewhere -- and fails its known negative.
Eleven checks.

Not assumed: whether the memory survives a reboot, or whether any other screen
has it. Their reach is one boot, one round trip, one direction. The finding also
reframes this morning's initial-focus warning without settling it -- if focus
persists, a reading not taken on a fresh boot's first entry is measuring history.
NEW GAME stays authored, on its own reasoning.

edd5af5be5 port: take formats-pin-2026-08-30b and stop owning the +0x08 read
The tag was cut within the iteration, so screen.rs now calls
ui_layout::loop_length_units and its local RATC guard and byte read are deleted.
One line, as predicted -- and the doc comment promising that deletion is the only
reason a temporary reading did not quietly become permanent.

A pin bump moves the whole crate, not one function, and this pin is recorded
load-bearing, so both commits between the tags were read before taking it:
b5df02a adds the public function, d020845 is comment-only -- two 'fixed code
under an unfixed description' corrections. No behavioural change in either, and
the oracle RMSEs confirm it: main_menu 13.21, extras 13.38, title 14.16, all
identical across the bump.

d020845 is worth noting for what it is. The rest override's comment still claimed
it tested the shifted time reading that the record-layout fix had refuted, and a
continue branch was documented with the pre-fix rule. Both are the same failure
this port hit in spin_period_units: a doc comment describing the rule the body no
longer implements. Three instances now, across two agents and two languages.

examples/record_loop_control.rs deliberately did NOT follow the API. The moment a
control calls the thing it exists to check it stops being a control and becomes
the API tested against itself; the falsifier means something only because the
reading is independent. Re-run at the new pin, unchanged. So the port holds one
copy of this reading instead of two, and it is the copy whose job is to disagree.

f7fee7a77f port: check the walk as well as the contract, and a defect I nearly filed off a debug pin
docs/game/navigation.md is a second document unreachable from main, and
authored/flow.json is its executable form -- nothing in the port fails when a
label drifts from it. Three more checks in contract-check, anchored on the walk's
own text: the five main-menu labels in order, EXTRAS' three items, the cursor
wrap. Ten checks now, ten known negatives, all passing.

The manual audit behind them found nothing else: initial focus is already
kind:authored citing Q5's instability, left_right is an explicit no-op,
auto_repeat is measured, unexported destinations are marked blocked with reasons.

Refutation target: the walk's claim that the ring is the ONLY thing moving on the
settled menu. Cannot be tested against the game from here, but can be tested
against my renderer, which is the direction that matters. Five renders across a
full ring cycle: 1428 of 921600 pixels vary, 0.155 %, one 46x44 cluster beside
the focused item. The port animates one ring, not five -- worth checking, since
all five ptbtn01f..05f declare the same 120-unit cycle and a renderer running all
of them would look identical until you diffed frames.

Then I nearly filed a serious P5 defect against myself: sweeping --leaf-time with
the ring pinned moves 10.4 % of the frame, full-screen. It is not a defect. That
pin addresses the build-in -- ptloop01 runs t=0..600, ptloop02 t=0..720 -- and at
settle both park off-screen at x=1521 and x=-839, with loop_leaf_on_screens
scoped to the title alone. The general form: a pin that can address states the
screen never occupies will manufacture defects on demand, which inverts what the
three pins are for.

The +0x08 ask came back answered and is not consumable. ui_layout::loop_length_units
is public at b5df02a and byte-for-byte what screen.rs holds, so the deletion is
one line -- but Cargo.toml pins a tag, no tag carries that commit, and swapping a
deliberate pin for a bare rev on an unmerged branch is not a move to make alone.
Asked for a tag; keeping the guarded local read.

ad80938efc port: check the contract's numbers instead of reading 4111 lines of it
HANDOFF on main is 926 lines frozen at 0fd8e69; the live one is 4111 at 27938aa,
99 commits and 70 sections this port has never opened. 'Read the other one' is
not good enough -- more arrive daily and nothing says which of them contradict
what the port ships.

tools/port/contract-check pulls each expected value OUT OF THE LIVE HANDOFF TEXT
by pattern, never restating it, and reconciles it against export/ and authored/:
the three fade quads' poses, the fade-out ramps, the plate glow cycle, the menu
BGM loop window, the black hold, the menu bank, and the boot splash dwells. All
seven agree. It reads the newest HANDOFF on any ref and prints how far the
working tree's copy is behind.

Three outcomes, and ANCHOR LOST is the point: a check whose pattern no longer
matches the contract has stopped checking, and passes forever while measuring
nothing. Reported as loudly as a mismatch.

--control perturbs the contract one token per check -- 120 becomes 121, -ss 9.44
becomes 9.45 -- and requires every check to fail. All seven do. Without it these
would be seven passes from an instrument nobody had seen react to anything, the
same unfalsifiable clean run the suppression count fixed in check-claims. Both
steps now assert in check-all.

Refutation attempted on 'your menu fade-in is 5x too slow', which corrected a
0.97 s fade-in to 12 units after their helper was found reading each pose's time
from the next record's word. The port never held that number -- ScreenView
animates pteff00 from its own exported keyframes, so the error could not reach
it, the second consecutive iteration where an instruction was aimed at a state I
was not in. But it makes the export an independent check on the correction, and
it holds exactly: their rebuilt tools and my pinned crate are different readers
of the same bytes, so agreement means both got the record-layout fix -- which is
what their helper had not had. Same for the 190/145 splash retraction, now
re-derived a third time.

Filed for the human: only a human merges a topic branch, so the port cannot land
HANDOFF on main and will not merge another agent's branch into its own.

c909d1dc49 port: the contract I read is 3185 lines shorter than the contract
docs/port/HANDOFF.md on main is 926 lines, last touched 0fd8e69 on 2026-08-29.
The live one is 4111 lines at 27938aa, +3930/-745 across 96 commits I have never
read, several of them addressed to the port by name. The Decoder writes HANDOFF
on origin/auto/no-disc-and-menu-captures; main is a hundred-odd commits behind
it; I open main's copy every iteration as instructed.

So the rule meant to prevent this cannot detect it. tools/port/blocked-provenance
recovers each row's derivation from history rather than memory -- git log -S on
the row's key phrase -- and all 27 open rows derive from 0fd8e69, because
HANDOFF-on-main has not moved. A constant cannot separate a fresh row from a
rotten one. Withdrawn in BLOCKED.md: 'HANDOFF has not moved in four milestones'
was missing the qualifier that carried its meaning.

The tool's first version silently missed its own known positive: P6 looping vs
712cac8, whose 9.44 s answer this port already ships. 'looping' did not stem to
'loop', 'menu' was stoplisted, and a >=2-shared-words threshold dropped the rest.
The threshold was the defect -- two common words outscored one rare one -- so
ranking is now by log(N/df) with no cutoff at all, and the control passes at rank
1 of 7 without touching the stoplist. Every discard is counted: struck rows,
sub-rank pairs, stoplisted words. Same rule applied to check-claims, which now
reports the 40 occurrences it suppresses; the Decoder reached it the same day
from the opposite failure, a silent suppression path making a clean run
unfalsifiable.

The reading list found two open rows already answered: the plate's pulse period
(120, not 105) and the main menu having no idle self-return, which refutes the B
row's own reasoning.

Refutation attempted on '+0x08 is the loop length', the claim the port was about
to build on. It survives: their falsifier re-run on my own read of the disc gives
0 violations in 1781 records, and on the eight records this port animates their
table reproduces cell for cell. Adopted -- screen.rs exports loop_length_units
and ScreenView._loop_period prefers it, announcing any disagreement rather than
silently resolving it. The value does not change: authored/timing.json already
had 120 from a wall-clock measurement, so a disc field and an emulator stopwatch
agree while sharing no instrument.

Two asks filed: the field is exposed in no public API on any ref, so the port
reads four bytes it should not own; and eleven focus records declare the same
120-unit cycle while only the plate is authored to animate, which is behavioural
and not mine to infer.

Every asserting check passes; oracle RMSEs unchanged, as 120 == 120 predicts.

6a45196a84 port: Q10 correction does not reach me; the register's cost is per-mention
Their stale Q10 row does not touch my tree: stems_why already reads 'a bank is
exactly TWO waves of identical duration', the corrected understanding, and the
three-sub-waves discrepancy is recorded here as refuted. stems: sum unchanged. Nor
do I cite their coherence discriminator, which they flagged because its own
control showed L-vs-R within one wave reading 0.22-0.50, so its premise fails in
this material.

Adopted their paraphrase resolution: the register entry is the verbatim home of a
dead phrase and prose paraphrases freely, since they are different documents. That
resolves the prose half but not my hook, and I wrote the limit into the tool -- it
detects whether a section contains a registered phrase, so it will always
over-report on well-written corrections, mixing 'never registered' with
'registered and paraphrased'. A prompt to check, never a defect count.

Fourth instance of the recursive cost, incurred while documenting it: writing that
comment quoted a registered phrase and check-claims failed, as did the previous
entry explaining that the corrected heading no longer contains it. Both marked.

So the cost is not per-correction but per-MENTION, and mentions multiply once the
register becomes a subject. Four instances, each inside text about the mechanism.

20227d7734 port: full regression passes; the phase term moved two published rows
Ran the suite after a session of edits to boot.gd, screen_view.gd, four tools and
two authored files. Every asserting check passes, and verify-screen's two DIFFERS
are the named pair with per-screen reasons.

Two oracle rows moved: title_plate 12.83/0.00% to 13.04/0.09%, title_band
15.31/0.35% to 12.86/0.00%. Opposite directions, which is a phase change rather
than a regression, and the cause is mine -- adding --leaf-time=0 to
verify-capture's render sites pinned the sweeps while the captures froze them
wherever the shutter caught them.

That makes the capture-phase term concrete: I documented +/-5.56 for title from a
sweep, and here it moved two published rows from a one-line harness change. It also
touches a number I published -- the boot-end-frame 0.00% was measured before the
pin, and the equivalent row now reads 0.09%. Both inside the term, and the right
reading is that neither is 'the' number.

Also narrowed the withdrawal-time hook. Its regex matched headings ABOUT
corrections rather than headings making them, so 33 was a measurement of the
regex; narrowed to a leading WITHDRAWN/CORRECTION/Refuted, it gives 10, all
genuine retractions.

Residual limit named: several of the ten are flagged because the registered phrase
does not appear in that section -- the corrected JP heading reads 'does NOT go
against the port', which does not contain 'goes against the port'. The register
wants the claim quoted; a good correction paraphrases it away.

d87ad98513 port: their 0.32 retraction dissolves a tension I recorded -- both halves gone
They retracted RMSE 0.32 as a noise floor: their plate-pulse gate phase-locks the
shutter to the title animation, so it measures their trigger's repeatability
rather than the game, and 11.9 is the replacement title-capture figure.

Checked my tree. Two hits: one is my own unrelated splash ink measurement that
happens to read 0.32, the other is a genuine citation. My entry used their 0.32 as
evidence the sweep is absent on the JP title, creating a tension with my EN curve
that I recorded as unadjudicable.

Both halves are now gone. Half one was settled by their draw-stream run -- the
leaves are drawn and free-run, so present was right. Half two is retracted at
source: two captures at the same animation phase show identical content in the
sweep band whether or not the sweep is drawn, so the figure never argued absent.

I built a tension I could not adjudicate out of a number that carried no
information about the question. It looked like a conflict between two
measurements; it was one measurement and one artefact of a trigger.

4924182942 port: localise the off-edge splash residual -- 98% of the area is exact
Tested the last signature on the open residual: is it positional? A sub-pixel or
resampling difference makes the residual track local gradient. Rule stated first,
r > 0.5. Got +0.109 and +0.307, and the brightness control settles it -- on
developer_logos brightness correlates more strongly (+0.471) than gradient, so the
gradient signal is not distinguishable from 'content is where things happen'. Not
positional.

The brightness correlation pointed somewhere better. Signed residual by capture
brightness, off-edge: 843025 of 857573 pixels on publisher_logo and 812111 of
850869 on developer_logos sit in the 0-15 band with a residual of -0.00. So 98% of
the off-edge area is exact, and the entire 0.82-1.42 RMSE comes from the ~2% of
pixels that are lit.

Within those the sign is inconsistent across bands and across screens -- publisher
+1.68, -1.09, -2.48, +0.45 against developer +2.19, +0.74, -1.57, -0.96 -- so not
a global gain and not a global curve, consistent with a per-level LUT fitted on its
own pixels improving them by only 1.6%.

Three mechanisms now ruled out with evidence: global tone, texture decode,
positional. Still no mechanism, and naming what it is not four times is not
finding what it is.

006bb4bcd1 port: run their absence shape on my citations -- five stale paths, and a wording gap in my P0 closure
Their finding was about their own audit: evidence exists in three forms and their
check looked for one, so '48 citations, 0 missing' was a statement about the
data-file form -- reported in the wording rather than the scope.

The analogue: do my own citations resolve? 32 paths cited in DECISIONS.md, 12 do
not. Inspected before publishing -- fifth instance of that habit here -- and most
are relative fragments, the Decoder's branch files, a historical absolute path,
and a hypothetical modding example. Genuine: five stale citations from the docs/
-> docs/port/ reorganisation, rewritten.

And one reached a claim I published last iteration. P0's gate says the export
'validates against FORMAT.md'; my closure reported the validator saying '16
screens validate against sylpheed.screen/3'. Different words, and I certified the
gate on one while quoting the other -- their exact failure, in a gate closure
published as verified.

Checked rather than assumed: docs/port/FORMAT.md is 405 lines and contains
format: sylpheed.screen/3 as the specification, so the schema the validator
enforces is the one FORMAT.md defines and the closure stands. But it stood on an
unstated identity, and had FORMAT.md described a superseded format nothing in the
check would have said so, because the validator never mentions FORMAT.md.

Verifying in the tool's vocabulary and certifying in the gate's is a substitution
nobody performs explicitly.

91358db296 port: run their sufficiency check on authored/ -- clean, after nearly reporting 35 false positives
Their audit found 48 citations resolving and 0 missing, with the caveat that it
cannot see data a page should have cited and did not. The port-side analogue: my
earlier audit checked what a MEASURED stamp cited and could not see an authored
value carrying no why at all, which passes by being absent.

First pass flagged 35 of 131 values as bare. Every inspected sample was a false
positive: ptbtn01's label and goto sit in an object carrying five *_why siblings
plus a blocked explanation, and /voice/stream_weights/.../position is covered by a
_ key one level above, which the check only looked for in the same object.

Ancestor-aware, the real number is 126 values and 0 uncovered -- every authored
scalar has a why, _ or *_why in its own object or an ancestor.

35 was the instrument's resolution, not a finding. Third instance in one exchange
after their 9 raw hits going to 2 real and my 33 hook candidates: a first count
from a new detector is a measurement of the detector.

Their caveat transfers unchanged and is stated rather than glossed: this tests
that a why exists in scope, not that it explains that value. A parent _ covering
twenty values may say nothing about any one.

a4ed91bde6 port: record the P0 gate, verified -- and name the gap it belongs to
They were right that the P0/P2/P5 gap matters more than the P2 fix. P0 is the one
of the three I can close alone: its gate names no human and no emulator.

Verified both halves. export/screens/title/main_menu.json exists at 51011 bytes,
the validator reports 16 screens validating against sylpheed.screen/3 with that
file among them, and all 20 sprites it references open as PNG with 0 missing and 0
unreadable. P0's gate is met on an artifact and now written down; it had been met
for a long time and only the record was missing.

That is the argued-versus-indexed split one level up. The refutation register
taught it about deaths -- the page is where a refutation is argued, the index is
where it is found. Here the milestone was completed and never indexed: the work
existed, the artifact existed, the gate record did not.

Remaining: P2 verified and recorded last iteration; P5 is 'a human clicks through
it', which I cannot self-certify and will not try. Converting it into something I
can check would be rewriting the gate to fit the checker, which is the mission's
own warning about gating on 'it compiles' in a more flattering costume.

fbba0a0175 port: apply 'a correction is a new claim' to my own most recent correction
Their rule, from replacing a stale status with an unchecked one in the edit
criticising unchecked status: a correction is a new claim and needs the same check
as the claim it replaces.

I made that shape of edit last iteration. The blocker halves were checked -- I
confirmed Q1 and Q10 read 'answered' in HANDOFF before writing it. The gate half
was not: my correction asserts 'Gate met' for P2 and there is no P2 gate record in
DECISIONS.md at all. Written from confidence.

Resolved by measuring rather than withdrawing. ptbtn01 declares y 142 -> 162 across
t=28..34; rendering main_menu at both gives a changed region 307x215 at (542,162),
x and final y matching the declared button exactly, max difference 159. The port
does slide the buttons in, so P2's gate is met -- now on evidence.

Being right is the dangerous part: an unchecked assertion that happens to be true
does not announce itself, and correct-by-luck is indistinguishable from
correct-by-checking in the text.

The check also turned up that P0, P2 and P5 have no gate record while P1, P3, P4,
P6 and P7 do. P2 is now verified here; P0 and P5 remain unrecorded and unverified,
and P5's gate is 'a human clicks through it', which I cannot self-certify.

Their boundary holds: this correction would have passed my own withdrawal-time
hook cleanly. Neither mechanism tests whether a correction is true.

6ffd9baca9 port: build the withdrawal-time hook, and violate the rule it enforces while writing it
They ended with 'it needs a hook at withdrawal time, not a sweep'. Expressible,
because a correction here has a shape: a heading carrying WITHDRAWN / CORRECTION /
refuted. A correction section containing no registered phrase is a death argued
and never indexed. check-claims now reports them, and the first run names more
than my 'four of eight' -- the shortfall runs back through earlier work.

Reported, not asserted, deliberately: not every correction retires a claim, and
forcing rows for those would push rows in to silence the check.

Two failures while building it. The first version pasted the register rows into
its own heredoc, so every registered phrase became an unmarked quotation and
check-claims flagged its own source -- a tool violating the rule it enforces by
being written. Fixed by passing the register through the environment.

And writing up the previous catch re-introduced three unmarked quotations:
describing a refuted claim quotes it, so every correction is a new occurrence
needing the token. The cost is recursive, which the header implies but does not
say out loud.

What the hook does not do: it fires when a correction is written, so it closes the
gap between arguing and indexing, not between believing and arguing. Nothing here
would have caught me copying their 'structural' claim into my record.

f32d9e8f7d port: their REFUTED gap, in a register I had and fed nothing
Their finding: eight claims died this session and none reached REFUTED.md, the
file their brief says to grep before proposing anything. The pages are where a
refutation is argued; the index is where it is found.

Mine is the same gap and worse in one respect. tools/port/check-claims is a
register that FAILS the run if a refuted claim is quoted without its [refuted]
token, and it is in check-all -- so an entry enforces rather than merely
publishes. It held 7 rows, all from earlier work, and I added none while
withdrawing about 8 claims this session.

Registered four. The checker immediately flagged three still asserted unmarked,
and every one was inside a correction I had written myself -- the headings-audit
table rows explaining the withdrawals, and the EXTRAS withdrawal block. That is
the token doing what phrasing cannot: all three read as corrections to a human and
the marker fired anyway, because it tests for a token an author places rather than
for language that sounds retracted. Marked; the register now passes.

Scope: four of roughly eight registered. Not registered -- the compactness
precondition, the half-rate defect, 'the eras render identically', and my 16/16/18
rule -- each argued in its own correction and findable by nobody. Stopped at four
because each row costs marking every existing quotation by hand.

And nothing mechanically checks that a future withdrawal reaches the register.

33ab07ff2e port: finish the required-reading audit -- MODDING clean and checker-backed
Finished the second half rather than leaving it named. MODDING.md carries no
status markers at all, so nothing of the stale-blocker shape. But their finding
was about claims, not markers: it states five rules, and tools/port/check-modding
asserts all five by name, one section each, and passes in check-all. Those claims
are mechanically verified on every suite run rather than merely unstaled.

Of the five documents the brief names, three are mine: BLOCKED.md (five rows
struck earlier), PORT-MISSION.md (two stale blockers corrected), MODDING.md
(clean, checker-backed). PROTOCOL.md and HANDOFF.md are not mine to correct, and
HANDOFF as I read it is the stale main copy, which is its own recorded problem.

Also checks their 'a ranked list always has a winner' against my own matching. My
GP_TUTORIAL identification ran the control first -- my own title capture over
seven builds with a known answer, picking build 4 at +0.2792 -- and the submenu
then scored +0.4962, above the calibrated true-match score rather than merely top
of a list. No other nearest-match report exists in the tree.

b16d98ec41 port: PORT-MISSION.md had two stale blockers, in the file I read every iteration
Their finding was that MISSION.md carried three stale headings while they had
audited everything else. The diagnosis transfers: a document read only for
instructions is never read for review, and the more central it is the more often
it is consulted and the less often checked.

The brief names five documents to read every iteration. I had audited BLOCKED.md
and never PORT-MISSION.md or MODDING.md. Two stale blockers in the table I am told
to consult to find the lowest unfinished milestone: P2 'Blocked on HANDOFF Q1 --
do not invent it' when Q1 is answered (ramp linear, 2 units/frame, 1 unit = 1/60 s)
and P2 shipped long ago; P6 'Looping is blocked on HANDOFF Q10' when Q10 is
answered and the P6 gate is recorded verified.

Worse than a stale heading in a record: a stale INSTRUCTION in a document whose
purpose is instruction, the class we ranked highest.

Scope: PROTOCOL says only the human changes a mission, so I corrected the factual
status clause and nothing else. Gates, requirements and asks untouched, original
struck through rather than deleted so the change is visible and reversible. If a
human reads this as a mission change rather than maintenance, revert the two table
cells.

MODDING.md is still unaudited and is named as such rather than quietly skipped.

9934aa48b7 port: check their incoming-primitive observation -- counter-example stands, and it cannot explain the intra-archive spread
They offered, with its counter-example attached, that the incoming screen's
full-screen primitive is [255] where the gap is 0 and [127] where it is 1, failing
on menu -> EXTRAS which declares a black backdrop and gives 1.

My first check got it wrong and would have dissolved their counter-example: I took
the FIRST full-screen primitive in element order and reported extras arriving at
alpha 64. extras has two such primitives; I read one and called it the screen's.

Corrected, all three GP_TITLE screens are identical in this respect -- pteff00 at
255 painting last, pteff02 at 64 -- so every one opens with an opaque black quad
on top clearing over 12-16 units, extras does arrive at 255, and their
counter-example stands.

The sharpening: within GP_TITLE this quantity is CONSTANT, so it cannot explain
any variation among the four intra-archive pairs. It could only separate GP_TITLE
screens from outside ones, which is much narrower than 'begins from black implies
no blank frame' and is already contradicted by menu->EXTRAS 1 against
menu->other-2 0, both arriving at an opaque incoming.

Their new pair kills the origin story from my side too: the menu gives {0,1,1,0}
across four destinations, both extremes from one origin.

ef9348f26d port: verify the overlay leaf-pin fix live, with a negative control
Recorded that fix as inert because press_start carries no leaf, which left it
unverified. title carries the leaves, so raising it as an overlay exercises the
path: pre-fix the two renders at leaf-time 0 and 4 are identical (the pin does not
reach, since the overlay's leaf read the frozen time_units in both runs);
post-fix they differ by max 105.86 and the announcement reports
overlay(leaf=0.0) against overlay(leaf=240.0).

A proper before/after -- the negative control shows the failure the fix removes,
not just the fixed state working. The configuration is synthetic (--overlay=title
over main_menu is something the game never does) but what it tests is the wiring,
which is screen-independent.

Process failure worth keeping: I reverted with a text patch to run the control and
the restore script half-failed, removing the line and throwing before replacing
it. What caught it was two independent checks disagreeing -- grep reported the fix
absent while the render comparison reported output matching the fixed run. Had I
printed only the render check I would have concluded the restore worked. Restored
with git checkout, tree clean, verification re-run gives the same 105.86.

Reverting a committed change by editing text is choosing the fragile path when the
robust one is one command away.

e88fc78c3a port: the ordered pair determines the gap; nothing declared predicts it
Their run gives five replicates with no variation -- title->menu 3,3,3 and
EXTRAS->menu 2,2 -- while every differing value comes from a different ordered
pair, and the same origin gives different values to different destinations. The
origin constrains; the ordered pair determines.

That excludes a second model for black_hold_units: a constant was already out, and
keying on the outgoing screen is now out too. Only an ordered-pair key survives,
needing a measured value per pair.

Checked their 'nothing declared predicts it' from my export rather than taking it.
Outgoing close (15,10,10,10), incoming clear (12,12,16,12), outgoing span
(269,74,80,80) and incoming span (80,80,269,74) each have two rows sharing a value
with different gaps, so no single declared quantity determines it.

Did not search combinations, deliberately: four intra-archive pairs against many
candidate two-screen functions fits by construction, which is the error this
corpus has catalogued five times including my own 16/16/18. A formula found here
would be indistinguishable from one found in noise.

black_hold_units stays 0 meaning not modelled, now with two candidate models
positively excluded rather than one.

8337aaf29c port: test the half-guard they named -- it found a real gap on first use
They flagged that my pose line reports the pins from the variables in force,
never checked against a pin set but not reaching the view. I had recorded the same
doubt and not acted on it.

The case is the overlay: a second ScreenView with its own pins, while the
announcement read view.* only -- and the plate carries a looping focus record,
the clock in question, drawing from overlay.*.

Extended the line to report the overlay's pins, and its first use printed
overlay(loop-phase=0.0, leaf=free): overlay.loop_phase_units was wired and
overlay.leaf_time_units was not. A run requesting both had one pin reach the
overlay and one not, and the pre-fix announcement would have printed leaf=0.0 from
the main view while the overlay drew free-running. Their half-guard precisely.

Currently inert -- press_start carries no leaf, so the render is byte-identical
before and after. The gap was real, live for any overlay carrying a leaf, and cost
nothing today.

Fourth instance of their remedy of putting the qualifier in the text rather than
the reader's memory, and it caught something within a minute of existing.

b98220e049 port: I promoted their unverified claim to a fact against data I had authored
They withdrew 'EXTRAS's sole exit is (B) to the menu, so n=1 is structural' after
one screen info showed build 6 declares three buttons. I had recorded that claim
in DECISIONS.md as a limit 'that row cannot be strengthened by anyone', and the
refutation was in two of my own files: export lists ptbtn11/12/13 for extras, and
authored/flow.json -- written by me -- records ptbtn11 -> GP_MISSION_SELECT, a
destination outside GP_TITLE and exactly the exit they have now measured at gap 3.

A failure mode distinct from the rest of the session: not 'my claim outran its
evidence' but 'I promoted someone else's unverified claim to an established fact
in my own record, while holding the data that refuted it'. A message carries no
evidence -- the protocol says so -- and I copied a sentence out of one into
DECISIONS.md as a finding.

Their METHOD entry on distrusting 'structural' and 'impossible' gets a corollary:
they are worth distrusting hardest when someone else writes them, because they
arrive without the doubt the author would have had.

The second measurement weakens the ordering -- EXTRAS {2,3} overlaps title
{3,3,3}, so menu < EXTRAS < title no longer separates -- while strengthening one
control: menu and EXTRAS to another archive give 1 and 3, so the destination is
not the variable. black_hold_units stays 0 and is better supported, since neither
the menu nor EXTRAS is single-valued.

940175d62f port: verify every documented invocation -- one runs forever and did not say so
Flagged the --boot family as unverified three iterations running, deferring each
time on cost. Done: --boot terminates at 156 s on title+plate; --skip-at=1 puts
the title at 7.80 s against 152.54, so the skip is real and quantified;
--film with --film-interval=0.5 writes 375 frames; --play hands over with 'menu on
title' at 7.77 s and stays live by design.

And --boot --film= never terminates. The boot-quit branch is gated on _film ==
at line ~499, and a second quit path on the same condition, so a filming run keeps
capturing past the title forever -- measured still filming at 300 s. verify-dwell
wraps it in timeout so the behaviour was known to whoever wrote that tool, but the
documented example is bare and a reader following it gets a process that looks
hung. That is the failure boot.gd's own header warns about, committed in its own
usage block twelve lines away. Fixed with the measurement.

The deferral was the mechanism: three times I judged the cost too high and
recorded the judgement honestly, which kept a non-terminating documented
instruction alive for three iterations. 'Too expensive to verify' and 'unverified'
are the same state and only one sounds like a decision.

Also records their correction -- the menu spans {0,1}, so even a per-outgoing-screen
key would not be single-valued, making 'not modelled' more robust; and EXTRAS is
structurally stuck at n=1.

51d8c4cdfd port: escalation resolved -- a uniform black hold is positively excluded
Their measurement orders the four gaps by the screen being LEFT: menu 0 and 1
frames, EXTRAS 2, title 3. Direction, button and incoming screen are each
positively ruled out -- the same pair both ways differs, (B) gives 0 and 2 while
(A) gives 1 and 3, and an incoming menu takes 3 from the title and 2 from EXTRAS.

That resolves the escalation I raised: a uniform value is not merely unsupported
but excluded, so 0 is no longer one option among several. It is the only honest
uniform choice, because it models the gap as absent rather than as constant.
black_hold_units is unchanged at 0; its justification is replaced.

And my own rule is now refuted rather than unadopted. Gap plus the incoming
screen's opening black-clear held at 16/16/18 on three transitions; their fourth
gives 16, 14, 16, 18, and decisively the two transitions with the same incoming
screen have different gaps, so the incoming screen cannot determine it. A fourth
point did to a three-point fit exactly what it should.

Not keying per outgoing screen: three screens with one value each restates the
data, which is the objection I raised against my own 16/16/18. BLOCKED row
rewritten to ask for a second value on any one outgoing screen.

1e02008f55 port: branches announce themselves -- their lesson, applied where it already bit me
Their salvaged iteration produced the rule I most needed: have each branch
announce itself in the log, so a run that took the wrong path says so before its
numbers are read. Assertions catch the edit; log lines catch the execution.

Two of my own failures were of exactly this shape. --no-hold under --time produced
byte-identical renders because --time sets frozen and pose_at tests 'holding and
not frozen' -- a request silently overridden reads exactly like one that worked.
And I enumerated three free-running clocks, wired two, and a run pinning two of
three looked identical to one pinning all three.

Both now announce. --no-hold prints INERT with the reason when --time is present,
and the pose line carries the effective configuration of all three clocks:
'pose = timeline [frozen, loop-phase=free, leaf=free]' against
'[running, loop-phase=0.0, leaf=free]'. The second prevents precisely the failure
I shipped -- pinning a subset and reading the result as pinned.

Verified the harnesses are unaffected: nothing under tools/port/ parses that line.

Also accepts their scope correction: a claim about code needs its ref attached,
the same way a number needs what it is a number of. With main 145 behind and both
of us on topic branches, 'the code contains X' is underspecified by default, which
is how we were both correct about SYLPHEED_KF_TIME_SHIFT simultaneously.

3f2abebb60 port: close their XPR lead, and find their class in the lane I called clean
They flagged five XPR_* texture toggles as relevant since I consume textures, and
my off-edge splash residual -- non-tonal, ~0.5 RMSE above quantisation, no
candidate -- has the shape a subtle decode difference would produce.

Closed: the toggles live in texture.rs::decode_surface, shared by from_xpr2 and
cube_faces_from_xpr2, and my exporter calls neither -- sprites come from
t8ad::parse. t8ad.rs reads no environment variables in its 202 lines, so the
sprite path has no hidden freedom either. The candidate is eliminated with no
replacement.

Enumerating what my exporter reaches turned up SYLPHEED_KF_TIME_SHIFT, which they
reported as absent from crates/. True on their branch, false on mine: my
ui_layout.rs is the stale era and the knob is live at line 497. The pinned tag has
0 occurrences (2 of LEGACY) so export/ cannot be perturbed, but verify-screen
builds its reference from the workspace, which can.

Tested both directions: with the knob the reference reports rest t=12, the
corrected reading, and the era guard passes; without it, t=70 and the guard
refuses. So the knob is the working remedy that makes a workspace-built reference
usable, and it appeared in no tool, help text or instruction in my tree -- their
exact class, in the lane I had just told them was clean. The refusal message now
carries the remedy.

d9b1137c93 port: three live-but-undocumented flags, and a dead instruction I wrote while fixing them
Their newest class -- the instruction is dead AND the working one is undocumented
-- inverts last iteration's sweep. I checked documented->parsed; the reverse is
parsed->documented, and it enumerates, so it completes rather than samples.

Eighteen flags parsed, fifteen documented, three live and undocumented:
--film-interval and --skip-at (used by verify-dwell, in no usage example) and
--no-hold, which plays a screen past its rest instead of clamping each element at
its hold, documented in DECISIONS.md and absent from the header a reader consults.
A capability that exists only in an 11000-line record does not exist to anyone
reading the interface.

Then I documented it wrong in the same command. I wrote the example as
--screen=title --no-hold --time=6 and tested it: the renders are byte-identical
because --time sets frozen and pose_at tests 'holding and not frozen', so an
explicit instant makes --no-hold inert. Without --time the pair differs by max
253. I wrote a dead instruction inside the commit fixing dead instructions, and it
only failed to ship because I ran the example rather than trusting that a parsed
flag works -- the gap I had named one iteration earlier.

Strongest evidence yet for their ranking: a wrong description costs a reader's
belief, a wrong instruction hands them a null result that looks like a finding.

ad8e18de7c port: sweep instructions above descriptions -- the silent class is clean, two loud hits
Their sharpening: a stale instruction manufactures a false confirmation, strictly
worse than a stale description that merely misleads. Applied to my instruction
surface, the documented invocations in tool and script headers.

All fifteen distinct flags across those examples are parsed, so nothing in my
headers can produce their failure mode by being inert. But 'parsed' is a proxy and
its gap is known -- --shots parses and does nothing on the --boot path -- so I ran
two documented examples end to end rather than trusting the grep, and both produce
a 1280x720 frame.

Two hits, both loud rather than silent: 11 references to tools/verify-capture and
tools/verify-screen, paths that do not exist since the tools are under tools/port/
(fixed in 4 files); and check-all claiming eleven tools where there are fourteen
(now states both so the sentence dates itself).

The distinction worth recording: mine fail loudly, theirs failed silently. A wrong
path announces itself; an inert environment variable returns a clean wrong result.
Both are stale instructions and only one manufactures evidence.

Honest limit: I tested the flag surface plus two examples end to end, not all
thirteen documented invocations -- the --boot ones take 156 s each. That is a
judgement about cost, not a claim of coverage.

af4e755579 port: audit headings -- my own index was republishing withdrawn claims
Their third mechanical search, audit headings first, lands harder here than on
their side because tools/port/index-decisions builds a table of contents FROM the
headings. A withdrawn claim was not merely sitting above its correction, it was
being republished at the top of the file as a live finding.

Three hits. 'The JP title capture adjudicates title_jp -- and it goes against the
port' asserted the opposite of the finding: I scored --pose=rest, which the port
does not ship, and posed as it runs the port beats the reference +0.9994 to
+0.8727. 'The leaf phase was an arbitrary choice; the capture turns out to
determine it' was refuted 97 lines below by the replication on title. 'Nested
leaves may advance at half rate -- a quantified defect in shipped output' is not a
defect, since the rate it is quantified against is known wrong.

All three now lead with the correction, original quoted and demoted beneath.

Scope stated because the number is unflattering: I audited the ~30 headings from
this session plus one older one I remembered, out of 211. Roughly 180 unaudited,
and older headings are likelier to be stale, not less. This is a sample, not a
sweep.

The generalisation: an index is an amplifier. Any mechanism that republishes
headings multiplies the reach of whatever they assert, including wrongly.

4956740c42 port: the dead-rule grep found two more, and the cause is my correction habit
Their generalisation of my 'untimed' marker -- search for the vocabulary the dead
rule needed -- is the cheap version and it works. Swept for the nouns of every
rule refuted this session. Two real hits: verify-screen:57 still asserting 'all
four are COMPOSITED rather than standalone', the reading withdrawn after they
tested it disc-wide at 7.9%; and boot.gd:197 opening with the pre-fix 'no time
slot' claim before retracting it.

Third and fourth instance after spin_period_units and exit_ramp_units, and in all
four the correction sits below the false claim in the same block, with both
written by me. The diagnosis is a habit: my corrections are ADDITIVE. I append a
CORRECTION block and leave the original standing, which is right for a record and
wrong for a statement -- a reader takes the first assertion and the retraction
three lines later has already lost. The habit that creates these is the same one I
adopted to make corrections honest.

Fix: keep quoting the original but demote it grammatically, leading with 'what
this used to say'. Both rewritten. Verified comment-only by artifact rather than by
reading -- the main_menu render is byte-identical before and after.

Also records agreement with their caution: the failed gap+clear rule was rejected,
not narrowed to menu transitions.

8fac01ed4e port: sweep for their tell -- two descriptions my own code had already refuted
Their sweep cleared my three quoted figures: the splash dwell spans were corrected
today, and the gap and cold-boot intervals are capture-derived, which the
record-layout fix cannot reach.

Their sharpening -- the tell is not that a number changed but that a page hedges a
quantity it should not need to -- made a sweep of my side possible. The marker is
'untimed', since there are 0 untimed keyframes in 866. Two hits, both worse than
hedges: descriptions their own code had already refuted.

Hit A: spin_period_units' doc stated the rule as 'the first timed and the second
untimed', the pre-fix version, while the body directly below carries a block
explaining that this rule silently stopped the ring and implements the span-based
replacement. A function and its documentation disagreeing, with the documentation
stating the refuted version.

Hit B: exit_ramp_units' doc claimed the value is authored in timing.json and that
the disc has no time slot on that keyframe. Both false -- the entry was deleted as
progress and the corrected layout times every pose. And I wrote the correction
myself, immediately below it, two iterations ago without looking up.

Both are fixed code under an unfixed description, with the fix and the falsehood
within twenty lines of each other -- not drift, but editing at the point of failure
without re-reading the frame around it. Their practice of quoting the original
sentence is adopted so the change is visible.

2799551821 port: black_hold_units tripwire has tripped; escalating rather than choosing
I set the value to 0 with an explicit condition: revisit at the next measurement
that is not 0, or the moment a rule appears. Five measurements now exist -- 0, 4,
6, 6 from the Decoder and ~7.9 from my own verify-dwell shortfall, which arrived
by a different route when the tool stopped absorbing it into slack. Four of five
non-zero, mean 6.0.

Attempted a rule so that any change would be principled rather than fitted: does
the incoming screen's opening black-clear absorb part of a fixed black period? Sums
are 16, 16, 18 on the three menu/title transitions -- suggestive given +/-1 frame --
and 7.9 on the splash pair, whose backdrop is a single keyframe at alpha 255 and
never clears. Three points fitting a constant with one outlier is a fit with an
exception, not a rule. Not adopted.

So my justification for 0 has failed on its own terms -- it now omits a real
quantity on most transitions, which the tripwire called a different invention --
and the alternative is a fit chosen for its residual. Both invent, so this goes to
BLOCKED.md with the numbers rather than being settled by whichever error I find
more comfortable. Value stays 0 pending that, with verify-dwell reporting the
shortfall.

fe01c3e221 port: sweep my own tool headers after theirs -- two hits, both in verify-dwell
Their audit found one defect in sixteen commands and their point that doing one
and stopping is the failure applies to me: I had fixed verify-screen and
verify-capture and gone no further.

Hit 1: verify-dwell built its target as oracle span + the GAME's black gap and
scored the port against it, correct only while the port inserted that gap. It does
not -- black_hold_units went to 0. On publisher_logo the port runs 0.131 s below
the unslacked target, absorbed into an 'agrees' by 0.15 s of slack that is larger
than the omission it hides. Hold now read from authored/timing.json; the game's
gap printed as its own term.

Hit 2: the tool carried '4 presented frames at 2.284 units/frame'. The number is
right but it is the disc used as its own clock on ONE capture that ran at 13.1 fps
against ~28 elsewhere. Stated bare it reads as a general rate and would contradict
Q1's 2 units per rendered frame, a different quantity at normal speed. The
derivation was in DECISIONS.md; the tool inherited the value alone -- exactly
their defect, and their 'print the population beside the number' fix applies
unmodified.

Not found elsewhere: check-capture's percentages all name their population;
check-claims, check-modding, index-decisions and strip-padding assert no measured
quantities.

0f93559ee1 port: verify-dwell built its target from the GAME's black gap while the port's is 0
Audited my own tools the way they audited theirs. verify-dwell built its target as
oracle span + the GAME's measured black gap (0.114-0.190 s) and compared the port
against it -- correct only while the port inserted that gap. It does not:
black_hold_units went to 0 three iterations ago.

So the port is expected to run short by the gap, and on publisher_logo it does --
0.131 s below the unslacked target, which the 0.15 s wall-clock slack was quietly
absorbing into an 'agrees'. A verdict that passes because the slack happens to
exceed a known omission is not a verdict.

The hold is now read from authored/timing.json so it cannot drift again, and the
game's gap is printed as a separate term with the note that the slack is larger
than it.

62ff9e48dc port: my backdrop predicate is exact in GP_TITLE and its reading was wrong
I offered 'a declared opaque-black backdrop distinguishes standalone from
composited' and asked for it to be tested against archives I do not have. It was.

The split reproduces exactly: derived independently from the disc, GP_TITLE gives
12 with and 4 without, the four being entries 0-3 -- my build_00, build_01,
press_start, press_start_jp -- with element names matching. Two genuinely
different paths, my export against their disc reader.

The reading does not survive. Disc-wide the predicate is rare, 76 of 965 builds at
7.9%, with GP_HANGAR_ARSENAL 0 of 390, GP_OPTIONS 0/14, GP_PAUSE_MENU 0/6. Read as
'composited' it makes 92% of the game composited, which the archives do not
support.

What survives is narrower: it separates screens that BEGIN FROM BLACK from
everything else, and their sharpening is the part I would not have reached -- the
negative class is heterogeneous, so a two-way rule cannot express it.

My caveat named the exact test that refuted the reading, but I still put the
refuted interpretation into verify-screen's header as a stated fact while the
hedge lived in DECISIONS.md. Corrected, with the 7.9% figure and an explicit do
not carry this into the four unexported archives. Hedging in the write-up does not
protect the claim shipped in the tool -- the same delivery gap as the
capture-phase term, repeated four iterations after fixing it once.

Within GP_TITLE the rule is exact and --black for those twelve is justified from
the file rather than assumed.

406dc75179 port: audit the --black premise -- declared on 12 screens, assumed on 4, all composited
Their finding that screen render --black's premise is declared on the splash
builds is checkable across my whole export, and verify-screen passes --black to
all sixteen screens on that premise.

Audited by asking whether a screen declares a full-screen untextured primitive at
t=0 with fade_argb 0xff000000. Twelve do -- pteff00 on both titles, both menus and
both extras, palogo_eff0 on all four splashes, pgloading_eff00 on build_12/15.
Four do not: press_start, press_start_jp, build_00, build_01.

All four exceptions are composited rather than standalone. press_start is one
element, the plate, whose own name_why records it is composited over the title.
build_00/build_01 carry the pgloading_* set without the pgloading_eff00 backdrop
that build_12/15 declare.

Harmless where used: verify-screen gives --black to both renderers so the
assumption cancels in a consistency check, and verify-capture already scores the
plate over the title rather than on black. The exposure was real and the tooling
had already routed around it, which could only be established by looking.

The rule that falls out: a declared opaque-black backdrop distinguishes a
standalone screen from a composited one, derivable from the file rather than from
a name. Recorded as a rule with its evidence -- sufficient as observed, not proven
necessary, on four exceptions.

5935638dd0 port: the fifth member of the family is mine -- 'drawn' read as 'visible'
Their revision confirmed from my export exactly: palogo_sqex_eff ramps 0->255 over
t=0..15 while palogo_sqex is still at alpha 0, so the screen is lit before the
logo appears and its visible span IS the full group. Their withdrawal of the
systematic stands on my data too.

Checking it exposed my own version of the error. My earlier 'visible 0..251' came
from counting any element with alpha > 0, which includes palogo_eff0: a
full-screen untextured primitive with a single keyframe at t=0 and fade_argb
0xff000000 -- opaque BLACK. Drawn from t=0 and showing nothing. My answer was
right only because the _eff element really is lit early; without it my method
would have called a black frame visible. I published that definition in the same
message that corrected their span.

So the family has a fifth member and it is mine: 'visible' read as 'drawn'.

Also accepts their correction on framing: I called this the first where the
misread number was mine to supply, and it is not -- they supplied 240, I supplied
4.28 s without saying what it spanned, and the under-specification was mutual and
simultaneous.

Conclusion unmoved: full group 255 and 210 units, ratios mean 1.0146, Q1 stands
unqualified.

ad72a2e2bb port: refute the 8.5% splash-dwell systematic -- it is the span, not the clock
They challenged the dwell agreement: declared spans 240 u and 195 u at 60 u/s give
4.000 and 3.250 s against six cold boots whose ratios all exceed 1, mean 1.085,
implying 54-56 units/s. And that 240 units at 60 should give 4.000 where I report
4.28.

The port does not play 240 units. Their 240 is the visible span, the logo
element's 15->255. The port plays the whole group from t=0, and my export gives
the full spans as 255 and 210 units -- 4.250 and 3.500 s. My 4.28 and 3.58 are
those plus transition overhead.

Recomputed against what the port plays, the ratios become 1.011, 1.083, 1.028,
1.002, 1.001, 0.962 -- mean 1.0145 with one of six below unity, against their mean
1.085 with none below. The systematic largely dissolves.

Their practical consequence does not follow either: the gap is 0.174 s, not 0.42,
and on developer_logos the port runs 0.041 s LONGER than the oracle mean, the
opposite sign.

Fourth instance of the same family after pivot-as-extent, centre-track-as-bbox and
cycle-length-as-motion-duration: a visible span read as a played span -- and the
first where the misread number was mine to supply and I had never stated which
span the port plays.

What survives: publisher still runs long in two of three boots against the full
group. Much weaker than 8.5%, thin at three boots, and no support for changing
keyframe_units_per_second.

2c605eed07 port: verify the boot as a sequence -- path, timing and endpoint
Twice I wrote that the boot's 0.00% agreement is one frame, the last one, and the
boot could take a wrong path and still land correctly. Closed, with no new capture
and no new feature.

--boot --shots= writes nothing: _shots is wired to the --script path only. I was
about to build stepwise boot photography; the trace and verify-dwell already
answer the question, so I did not.

Path: the boot logs its transitions, and they match authored/flow.json's declared
sequence exactly -- publisher_logo, developer_logos at 4.26 s, video ADV at 7.78,
title at 152.54 with the overlay raised at the same instant, ending 156.48.

Timing: verify-dwell against the Decoder's three cold boots gives publisher 4.28 s
against 4.297/4.604/4.370 and developer 3.58 against 3.508/3.503/3.366, both
agreeing. And authored/flow.json's dwell is EMPTY by design -- the dwell is
declared and the port plays it -- so these are disc-derived timings agreeing with
three cold boots of the real game with no authored constant between them.

So the shipped artefact is verified on three axes: path from the trace, timing
against the oracle, final frame at 0.00% differing. Still unverified: the
intermediate frames themselves, and the 144.76 s video beyond the fact it plays.

748f2d5cb9 port: print the capture-phase term beside the numbers it qualifies
Their closing point -- the thread lived in messages and docs/re/, which by our own
rule means it was not delivered -- applies to my side. The capture-phase term was
in DECISIONS.md, but verify-capture is what prints the numbers it qualifies and it
said nothing: a reader saw title 14.16 with no sign that +/-5.56 is inherited from
where the shutter fell.

Now printed per row: title +/-5.56 regression only, main_menu +/-3.78, extras
+/-3.73, and both splashes marked as carrying no free-running element and meaning
what they say. Header records that --leaf-time=0 is a convention, not the game's
phase.

Also names a gap their own update exposes: they landed the leaf facts in HANDOFF,
correctly, but HANDOFF as I read it contains none of them -- their work is on
auto/build-ordinal-audit and origin/main is 145 commits behind. So the facts reach
me only through messages, the channel the rule says does not count. Writing it in
the contract is necessary and not sufficient when the contract lives on an
unmerged branch. My BLOCKED.md and DECISIONS.md carry the status sourced to their
sha so my tree does not depend on a HANDOFF I cannot see.

Second structural consequence of main being stale, after the Cargo.toml pin.

against the game rather than against the other decoder -- everything prior ran
disc->exporter->export against disc->their-reader, which shares the source.

The renderer self-check I started is abandoned. I predicted a changed band at x
949..1280 full height for leaf phase 0->30; measured 1177x70 at the top of the
frame, max difference 5.29. The prediction is mine and wrong: the leaf pivot is
[200,90], the source centre, but under 800% vertical scale the mapping from pos to
drawn extent is not the centre-offset I assumed. My arithmetic, not a demonstrated
renderer fault, and separating them costs more than the answer is worth.

Stopping deliberately. They classified the leaf clock as undecodable with reach
after four refuted models and noted the thread has cost both of us a lot for a
quantity nothing ships on. Recording an inconclusive self-check as inconclusive is
the end state, not a step toward another attempt.

0b7e6cc610 port: apply their linearity gate to my side of the ratio, and find an inversion
Their gate -- a slope is only a rate if its residual is random -- bears on the
ratio we built together, so I checked the half I supply. The disc side has no
residual: pteff03 is declared piecewise linear with identical segment rates,
+4.0000 px/unit over t 0..150 and again over 150..540, then a hold. pteff03a gives
-4.0667 then -4.0625, a 0.1% step. These are declarations, not fits.

The inversion: their gate failed on the strips of height 1134, which is pteff03 --
the one whose declared track is PERFECTLY linear -- and passed on height 1303,
pteff03a, whose declaration is the slightly non-uniform one. So the curvature is
not in the source data and is in the strip where the source is exactly straight,
which localises it to the measurement or to how the game advances the record.

Also offers an instrument question: their ratio implies px/wall-second of 121.7 at
default against 30.5 at limit 15, ~4x slower on screen. If their samples are guest
frames that says the animation runs 4x slower, which no fixed declared rate
produces. If they are wall-clock samples while the limiter slows guest time -- and
their own boot slowdown of 3.58x says it did -- movement per sample falls with
guest speed, which is the direction measured and would revive the wall-clock
model. Their 3.58x and 2.14 are two measures of the same slowdown and disagree.

Marks the 1.87x table's input as known-wrong rather than merely unpinned.

8e3760b85c port: the off-edge splash residual is not tonal, and I compared it to the wrong floor
Ran the per-level tone correction I said was untested, deriving the curve on one
splash and applying it to the other because fitting and scoring on the same pixels
succeeds by construction. developer_logos off-edge: uncorrected 2.7512, single
gamma 0.85 gives 0.9040, the cross-applied per-level curve gives 1.3795 -- worse
than a single exponent.

The control settles it: publisher_logo scored with its OWN fitted curve gives
1.4209 against 1.4440 for gamma 0.85. A tone curve fitted on those very pixels
improves them by 1.6%. If the residual were a tone-mapping error, fitting the tone
mapping on its own training data would collapse it. The residual is not tonal.

And it is smaller than I made it sound. I called 0.82-1.42 '15-25x the 0.06
rasterisation floor', but 0.06 is render-to-render reproducibility -- the floor for
asking whether the renderer repeats itself. For render-versus-capture the floor
includes 8-bit quantisation on both sides: uniform rounding is RMSE 1/sqrt(12) =
0.289, so two independently quantised images differ by ~0.41 before anything is
wrong. Against that, 0.90 is ~2.2x, about one level in 255.

Same error as comparing an in-box margin to a whole-frame spread, which I flagged
in someone else's work two days ago.

88b75f4e35 port: their Route 1 is closed for the whole archive, and the exit ramp fooled me again
They closed three routes to pinning the absolute leaf rate. Route 1 -- a top-level
element moving in the same capture as a leaf, so fps cancels -- failed on the
settled title.

Searched all 16 screens for a top-level element still moving at its settle
instant. Two hits, pttitle on extras and extras_jp, and both are false positives:
it arrives, holds from t=24, and the post-settle motion is the exit ramp at t=52
to 58, which plays only when the screen leaves. Third time the exit ramp has
fooled a census of mine, after counting it as the end of visibility and after
making every normal element look like a flash.

The negative generalises their finding: excluding exits, no top-level element on
any of the 16 screens moves at rest. holding clamps every top-level element at its
own hold and the only post-settle keyframes are exits, so no capture of any screen
in this archive can carry a top-level clock alongside a free-running leaf. Route 1
is closed structurally, not just empirically.

Also states something about the port's design I had not: everything that moves on
a settled screen is nested. The three free-running clocks -- looping focus record,
spin, leaf -- are all sub-records, which is now explained rather than observed.

Also marks the 1.87x table conditional, since its input is the rate they cannot
pin.

3f2dd46487 port: nested leaves may advance at half rate -- the title sweeps ship 1.87x too fast
Their corrected least-squares fit gives 4.287 and -4.348 px/frame against my
declared 4.000 and 4.063 px/unit: 1.072 and 1.070 units/frame, where Q1
establishes 2 for top-level elements.

My port drives everything from one clock -- boot.gd:375, time_units += delta *
units_per_second at 60 units/s -- and the leaf path reads that same clock. So the
title's sweeps cross in 10.0 s where the game takes 18.7, a visible 1.87x defect
in what the boot ships.

Not changed, and not only out of caution: keyframe_units_per_second is authored
from a measurement and governs build-in, transitions and the plate. Changing it
globally breaks the top-level timing Q1 measured; a leaf-only clock is a claim
about how the game works rather than about my renderer. That is a Q1 sub-question
and theirs.

Refutation attempt on their strongest argument: two strips agreeing to three
significant figures constrains the strips to EACH OTHER, not the absolute rate.
Both ratios come from one capture under one fps assumption, so a systematic error
scales both identically and the agreement survives. Their own untested candidate --
1 unit per 1/30 s at 28.5 fps gives 1.053 -- sits within that uncertainty of 1.070.

b8d1b397ea port: check their draw-stream result against my export -- three confirmations, one correction
Their oracle run refutes their own 'may not draw these leaves' hypothesis and
confirms my title curve from the game. Checked against my export:

Rotation: the export carries rotation_deg +30 on pteff03 and -45 on pteff03a,
constant across all four keyframes, matching their ROT flag. spin_period_units
returns 0 for four-keyframe elements so the spin override does not fire and the
port draws the declared angle.

Directions: ptloop01 runs -639 -> 1521, ptloop02 runs 1721 -> -839 -- their strip
A and strip B.

Height: a 30-unit phase step changes a band 1121x720 and 1137x720, full frame
height, which is what a 1134/1303 px strip on a 720 px screen must produce.

The correction: their rate check divided 2160 px by a 600-unit cycle to get 3.6
px/unit, but the last segment HOLDS. pteff03 moves over t=0..540 then sits at 1521;
pteff03a moves over 0..630 of 720. Corrected: 4.00 and 4.06 px/unit, predicting
8.0 px/frame against their measured 6-7. That widens the gap from 7.2-vs-6.5 to
8.0-vs-6.5, so 'the rate matches the disc' does not survive the corrected span,
and a lower emulator frame rate moves the prediction the wrong way.

A cycle length is not a motion duration -- same family as a pivot anchor read as a
drawn extent.

b34e7b10c0 port: the splash floor is glyph-edge antialiasing; off edges the port is ~1 RMSE from the game
The splash rows have no free-running element, so their residual is chaseable
without a phase term. It is not tonal: max 255 with 0.012-0.017% of pixels over
8/255, in opposite directions on the two screens. That is the edge-antialiasing
signature.

Tested against an edge mask from the capture, with coverage checked first because
an earlier attempt on title failed by classifying 92% of the frame as edge:
publisher_logo mask 0.67%, residual 18.30 on edges against 1.42 off;
developer_logos mask 1.44%, 12.66 against 0.82. Non-degenerate masks, 13-15x
concentration. The 1.92 whole-frame floor is glyph-edge antialiasing.

Off the edges the port matches the game at 0.82-1.42 RMSE -- the cleanest
port-versus-game statement in the corpus, and confirmation of verify-capture's
long-standing note that the port is +9 to +12 on sprite edges, measured rather
than observed in passing.

Not everything is explained: 0.82-1.42 is still 15-25x the rasterisation floor,
consistent with the binned tone table leaving about a level of error, but not
shown to be that.

Also records the contamination check after their withdrawal of the A result:
nothing in authored/, docs/port/ or port/ cites it or the '2 of 2' run count.

ff66d7c17b port: fit a gamma on the clean rows, and repeat a mistake my own tool documents
The splashes carry no free-running element, so they are the only place to measure
the capture's tone relationship without a phase term. Gamma sweep gives a clean
minimum at 0.85 on publisher_logo, developer_logos and title -- gamma ~1.18 in the
corpus convention, against HANDOFF's 1.34-1.49. I was about to report that as a
disagreement measured on the cleanest rows available.

verify-capture's own header answers it: the tone relationship is a curve, not a
best exponent, and two earlier versions of the tool reported an exponent and were
wrong. The binned table below it shows implied gamma falling with render level --
1.20 at 8, 1.18 at 24, 1.03 at 40, 0.93 at 48 -- with 511026 pixels in the dark
bins against 258823 above. My whole-frame fit recovered the pixel-count-weighted
average of a varying curve and would have published it as the gamma. Third time
this tool has been fitted an exponent, third time wrong.

The residual at best gamma is 1.92-2.06 on the clean rows, ~30x the 0.06
rasterisation floor, so a single exponent cannot close it.

What the clean rows do establish: the splash residual bottoms at 1.92 with no
phase term, so it is a real floor for those screens and still 30x the noise --
the port and the capture differ by something the tone curve does not explain.

238c0591ae port: withdraw the compactness precondition and the free-running claim; the minima are off-screen phases
They challenged the compactness precondition and my claim that the leaf free-runs
in the game. The precondition is wrong and withdrawn -- the same sweep crosses
their box and two renders one plateau-phase apart differ by 11.9 inside it, so
their crop excluded nothing.

Their hypothesis that the game may not draw these leaves makes a testable
prediction: the best-matching phase should be wherever the quad is off-frame. The
x track is (0,-639) (150,-39) (540,1521) (600,1521), so a ~400 px quad is
off-screen at t=0 and t=600 and on-screen from ~120 to ~480.

On main_menu the two RMSE minima are exactly the two off-screen phases, and every
on-screen phase is worse -- their prediction landing precisely. On title the
minimum is at 240, on-screen, with both off-screen phases worse -- the opposite,
fitting the sweep being present in that capture, which ORACLE-CAPTURES.md already
says of these elements.

So 'the leaf free-runs in the game too' is withdrawn as established: my two minima
came from two different screens. What the off-screen coincidence shows is
narrower -- the menu capture behaves as though the sweep is absent, the title
capture as though it is present. It does not resolve their JP tension either.

The settling test is theirs (draw-stream check on a settled title). The
contribution here is that the question has a per-screen answer to look for, and
main_menu is where the absent evidence is strongest.

12429be18f port: implement their masking rule; it does not transfer, and my phase term was too small
Their rule -- score inside a region excluding free-running elements and measure
the residual there -- implemented with the mask derived by measurement: five leaf
phases per screen, union of what moves. Free-running area is 3.68% on title, 1.63%
extras, 1.32% main_menu, 0.00% on both splashes.

The control fails. On extras, a 1% threshold masks 9.3% of the frame and removes
only ~16% of the phase term (1.7343 -> 1.4569). The rule is sound but conditional:
their free-running element is a localised pulsing plate they can crop out, mine is
a wide translucent sweep whose contribution is thin and spread. It cannot be cut
out without cutting out the picture.

And they were right that my ~1.0 was too small. In verify-capture's own metric the
term is 5.56 on title, 3.78 main_menu, 3.73 extras, 0.00 on the splashes. My
earlier figure came from a greyscale metric over a narrower phase range -- computed
one way, quoted as if it applied another.

The consequence sorts my oracle rows: the splashes carry no free-running element,
so 2.17 and 3.05 mean what they say; title at 14.16 carries +/-5.56, larger than
the spread between any two of my rows. Those rows are usable for regression at a
fixed pin and not for absolute comparison.

Recorded as a limit, not fixed: no pin removes it, since the term is the game's own
animation sampled at one instant by the capture.

6d663e2a3c port: the phase result does not replicate, and the failure reframes it
The Decoder established ptloop01/02 and their leaves are identical on entries 4, 5
and 7; confirmed against my export on every field. That makes replication
well-posed: same object, different screen, different capture.

main_menu minimises at 0 units (13.2059); title minimises at 240 (13.9417), with 0
at 14.1604. Spread 1.025 on the title, 18x the 0.0565 floor, so both sweeps are
decisive and they decisively disagree.

The meaning: the leaf free-runs in the game too, so each capture froze it wherever
it happened to be. The phase that best matches a capture is a property of when the
shutter fell, not of the game's rest state -- a continuously sweeping element has
no canonical rest phase to find. My 'phase 0 is the measured best of the cycle'
was measuring the capture, not the game. The hedge I attached was the right
caveat for the wrong reason: I framed a well-located property of a photograph as a
weakly-located property of the game.

Phase 0 stays pinned as a harness convention. NOT tuning it per screen -- 0 for
main_menu and 240 for title would minimise both and would be fitting each
capture's shutter moment, making the harness agree with the oracle by
construction.

Every row with a sweeping leaf now carries an irreducible capture-phase term of up
to ~1.0 RMSE, larger than most margins quoted from those rows.

bb1e4c4195 port: cross-check the leaf sweep against my export -- their reading and mine reconcile
Their withdrawal gave coordinates to check my renderer against, and my first
measurements looked like a contradiction: phase-to-phase differences span the
whole frame against their 400 px quad tracking x 921->1041. Fine steps showed the
shape -- nothing above threshold over 5 units, the entire frame over 120 -- a
large, slowly-moving object, and with --time frozen all of it is the leaf.

Reading the leaf record from my own export resolves it. ptloop01: leaf pteff03,
span 600, x track -639..1521, scale (100,600). ptloop02: span 720, scale (100,800).
Loop spans 600 and 720 differing from each other is exactly their reading from the
other side. Scale is 100% horizontal, so the quad is a normal-width strip
stretched vertically, and its x track crosses the entire 1280 frame -- two phases
120 units apart put it hundreds of pixels apart and the difference covers the
union, which is why the bboxes are frame-wide.

Their 921->1041 is a segment of that track, not its extent. The caution they
applied one level up applies again: a centre track is not a drawn extent either,
and I nearly wrote up a disagreement by comparing a sub-range against a full
sweep.

It also explains their dead zone: a strip anchored at the pivot sweeping at 100%
width spends almost all its time outside the 200x90 parent rect.

11a35651cb port: the capture determines the leaf phase, and phase 0 is the measured minimum
Last iteration I pinned the leaf at phase 0 for reproducibility and said which
pose the game shows was not settled by it. Asked the capture, with the decision
rule stated first: the spread must beat the noise floor decisively or 0 stays an
admitted arbitrary choice.

Phase 0 is the global minimum at 13.2059, rising to 14.08 mid-cycle and returning
to 13.2065 at 600 units -- margin 0.44-0.88 against a run-to-run floor of 0.0565,
8-15x, which meets the rule. 0 and 600 agreeing confirms the cycle closes,
independently supporting the leaf's declared span.

The Decoder's point is what makes it readable: the gamma offset moves every
candidate together and nearly cancels in the ranking, so nine renders differing
only in leaf phase compare cleanly on a ~13.2 floor nobody can remove.

Broad minimum -- 0 and 15 units identical to four decimals -- so this constrains
the phase to the first 15 units of a 600-unit cycle, not to a point, from one
capture of one screen.

And the sweep that nearly said the opposite: --leaf-time takes SECONDS, so my
first sweep of 0..500 was 0 to 30000 units, every value past the group end,
returning 13.2059 six times. Third instance of the seconds-versus-units confusion,
after --time=50 and after I wrote the identical-output tell into METHOD. Made
worse because 0 and 30000 genuinely coincide, so the flat reading was partly real.

e7163d5eb6 port: the third clock was in my own enumeration and I did not wire it
Last iteration I enumerated three free-running clocks, wrote that the leaf is
pinned only by --leaf-time, then tested reproducibility without passing
--leaf-time and concluded nothing free-runs on the menu path. The answer was one
paragraph above the experiment that contradicted it.

My own flagged weakness found it: deliberate wall-clock variation via
--script=wait:N, putting the capture at t=96 units against t=369. Spin pinned
only, wait 0.5 vs 5.0 differs by max 91.19 per channel; with --leaf-time=0 added
it is byte-identical. draw_leaf_for is ptloop01/ptloop02, present on main_menu and
not just the title, which is why that row drifted.

verify-capture passed --loop-phase=0 and not --leaf-time=0 -- I fixed the clock I
had been bitten by and left the one I had merely listed. Enumeration without
follow-through fails exactly like no enumeration.

Both are now pinned at all six render sites. main_menu returns 13.21 across three
runs and two renders after different waits are byte-identical.

The number moved 13.26 -> 13.21 and that is NOT an accuracy improvement: pinning
the leaf at phase 0 puts ptloop01/02 at one specific pose rather than wherever the
wall clock left them. A different configuration, now reproducible. Which pose the
game shows at rest is not settled by this.

df03c057f5 port: enumerate the free-running clocks, and test rather than enumerate
The Decoder's point was that this is an unenumerated set, not a missing guard. The
enumeration is possible on my side and found a THIRD clock: the leaf sets
holding = false explicitly and reads time_units, pinned only by --leaf-time or
--time, biting on loop_leaf_on_screens = [title]. I would not have found it by
waiting for a row to drift.

But the general answer is a test that fails when the set is non-empty. Render
twice with the known pins at different wall-clock moments and compare frames, not
a statistic. --screen + --time + --loop-phase: all 16 byte-identical, though
--time freezes time_units itself so that pins every derived clock. --menu
--script=wait + --loop-phase, where the drift lived: frames differ by 4378 px --
but max per-channel 2.86 against 158.4 for a genuinely moving element, 55x apart.
Nothing moves; the residual is rasterisation noise. The discriminating scale is
what makes the test an answer.

And the reason I nearly missed it: last iteration I reported three pinned runs
returning 13.26 and called the harness reproducible. verify-capture prints RMSE to
two decimals and the residual is 0.0565 -- below its own resolution. The frames
were never identical; the statistic could not tell. I verified reproducibility
with an instrument that rounds away the thing being verified.

Conclusion unchanged: 2.86/255 changes no result.

3751f86a86 port: the oracle harness was nondeterministic and I quoted it for a dozen iterations
verify-capture's main_menu row reads 13.30 / 13.27 / 13.25 / 13.26 across runs
this session while every other row is identical to the digit. I cited those
numbers repeatedly, including in the rest() adjudication.

Cause: the focus ring spins on time_units raw rather than the pose clamped by
holding -- deliberate and correct, since the ring is the one thing on a settled
screen that keeps moving -- so its angle at capture is set by the wall clock.
extras is stable because nothing there spins.

--loop-phase already existed and did not cover it: it pins the looping focus
record phase, while the spin is a second free-running clock I guarded once and
never connected. Extended loop_phase_units to pin the spin too, and verify-capture
now passes --loop-phase=0 at all four render sites.

The control matters because the drift was intermittent -- three unpinned runs gave
13.25, 13.26, 13.26, so three pinned runs agreeing would prove nothing. Phases
0/30/60/90 give 13.2583 / 13.1991 / 13.2637 / 13.2588: the pin is live and the
0.065 spread is the whole of the observed drift.

Non-finding recorded so nobody mines it: phase 30 scoring lowest is not evidence
about the ring's real phase -- 0.065 against a ~13.2 gamma floor is 200x too
small. A margin only means something against the noise it sits on.

No conclusion changes: the smallest margin any of them turned on was 0.14%
differing area.

d84c17457e port: count the fallbacks instead of inspecting them; black_hold's absence is now audible
The Decoder sharpened the sweep in a way that invalidates part of how I ran it: an
in-range fallback cannot be caught by inspecting output, because the output looks
exactly like the true case -- the only way to know is to count how often it fires.
My sweep classified defaults as identity or sentinel by inspection, which is
precisely the method that cannot see this.

Counted: rotation_deg -> 0 fires 0 times in 866 keyframes and 178 rest poses, and
ramp is present in authored/. So rotation is read, not invented -- the same
conclusion they reached for design size, reachable only by counting.

The count exposed one I had waved through twice: black_hold_units defaults to 0.0
and its authored value IS 0, so deleting the entry would be invisible -- same
behaviour, no error, and the reasoning in black_hold_why (four measured gaps, why
0 over the better-fitting 4 or 6, the tripwire) silently stops applying. Fixed the
same way as exit_ramp_units: fallback is -1.0 and an absent key raises an error
naming what was lost.

The control is the demonstration: key present 0 errors, key deleted 1 error, and
the render byte-identical either way. No output inspection could have detected the
deletion.

Does not change the value: still 0, still wrong by 4-6 units on three of four
measured transitions, still no rule. Only its absence is now audible.

5b0188f77a port: sweep the tree for values a deleted entry still supplies -- one instance, already fixed
The exit_ramp_units catch generalises: deleting an authored value does not remove
it if something supplies it silently, and authored/ is where a reader looks and
does not find it. Swept both halves of what I own.

GDScript: every keyed lookup with a fallback, cross-checked against the 121 keys
present in authored/. One hit -- exit_ramp_units, the case already fixed -- which
makes it the sweep's own positive control: the detector found the known instance
and nothing else. The other numeric fallbacks are identity or sentinel and invent
no quantity.

Exporter: 14 serde(default) sites, all attaching to Option, Vec or map types,
where an absent key becomes None or empty and asserts nothing.

My classifier produced a false positive I nearly wrote up: it flagged
also_export: AlsoExport as a semantic default because the type name lacks a
container prefix. AlsoExport is a type alias for a BTreeMap. Classifying a type by
the spelling of its name is the same proxy reasoning as inferring an era from a
line count.

Negative result, but from a check that demonstrably finds the known case.

bd1415b29d port: the refuted 24-unit constant was living in a default; make it loud instead
ScreenView.exit_ramp_units defaulted to 24.0 -- the constant HANDOFF ask 2 told
this port to author and that it refused, since the file's own ramp is 10 units.
The authored entry was deleted as progress when the corrected record layout
removed the unknown, and the default plus boot.gd's timing.get(..., 24.0) made
that deletion a no-op.

Both use sites are unreachable on today's export (866 keyframes, 0 untimed), so
the branch is kept for an older export but no longer invents: the default is -1.0
meaning not supplied, and an untimed group now raises an error naming the screen
rather than fabricating a duration.

My first verification accused the change: main_menu 641941 px and extras 226009 px
changed, on a branch that cannot execute and with no error raised. The cause was
--screen=X --capture= firing at an uncontrolled instant -- t=9.00 in the earlier
run against t=8.00 in the later one, one unit apart mid-build-in. Three runs now
are byte-identical, so it is not noise; the instant is stable within a session and
moves between them. Re-run with --time=1.0 pinned, old against new is
byte-identical on all four screens.

Records the harness limitation: --screen=X --capture= cannot be used for
before/after comparison on an unsettled screen, which also explains the earlier
settle-vs-rest confound.

Also corrects my overstatement that other tools call the CLI -- verify-screen is
the only one, checked.

90c5c308ac port: my branch IS the stale era, and verify-screen's reference was never its own build
Told the Decoder their diagnosis was wrong. They were right. ui_layout.rs is md5
b6c19d08 in my working tree, at HEAD, on my pushed branch and on origin/main --
one file, stale marker present, tree clean.

What misled me is the same trap a third time: CARGO_TARGET_DIR is a shared
/sylph-home/port/target-container, so two source trees write one binary and cargo
fingerprints per source path -- each build reports Finished while the binary on
disk belongs to whichever tree wrote last. A CLI built from my workspace is
3a39fce (stale, rest t=70), identical to one built from origin/main; the binary
verify-screen actually used was 8e0aa76 (fixed, rest t=12), from a tree nobody had
named. It happened to be the right era, which is worse than wrong -- it agreed
with the pin by luck and one rebuild would have flipped it silently, and title_jp
differs by 74507 px between eras.

verify-screen now reads the reference CLI's pteff00 rest instant and compares it
against the export the port reads, refusing to score if they disagree. Controlled
both ways: passes with the matching binary, refuses the stale one built from my
own workspace.

And the pin is load-bearing, not an annoyance to revert: the workspace crate is
stale, so the pin is the only reason the export is correct. Consequence worth
stating -- my published branch carries the stale crate, so anyone building
sylpheed-cli from it gets the stale decoder.

e11d843e72 port: WITHDRAW the 'eras render identically' measurement -- I compared a binary with itself
Last iteration I overturned check-all's allowance on a measurement of 0 pixels
between the two decoder eras, and rewrote the tool's reason around it. The two
binaries had the same md5: one built in a worktree at formats-pin-2026-08-30 and
one from the workspace, and both commits carry the record-layout fix. I compared a
binary with itself and reported the zero as evidence. The 508-line diff I cited
was real and irrelevant -- it does not straddle the fix.

Done properly against origin/main, verified stale by the Decoder's own control
(rest t=70 vs rest t=12) and by differing md5s: title 0 px, main_menu 0 px,
title_jp 74507 px -- reproducing their figure exactly, under their flags and mine.
My second hypothesis, that --animated masked it, was also wrong.

What survives: the era still cannot explain this script's rows, for a fact I had
not established -- both sides of the comparison are the FIXED era, since a binary
built from the pin and one from the workspace have the same md5. Right answer,
wrong evidence. The note now carries its condition: title_jp is era-sensitive, so
if the reference is ever built from a different era than the pin, that row's cause
changes.

Twice now a correct conclusion has come through a broken experiment, and both
times the tell was two things that should differ producing identical output.

92b58cc4c3 port: re-derive black_hold_units against four measurements rather than inherit it
They answered ask #2 -- the gap is deterministic, not a load -- and held me to
re-stating the choice against four measurements (0, 6, 4, 6) rather than the three
it was made on. That is my own standard for check-all's stale allowance turned
around.

The arithmetic moved against 0: it costs 2.0x the best fit on four measurements
against 1.7x on three, and is now the minority outcome, wrong on 3 of 4 where a
uniform 6 is wrong on 2 of 4.

Still 0, because the reason was never the fit -- it adds no black the game does
not have, and is measured-correct for a real transition rather than for an average
of them. Picking 6 because it appears twice is choosing a mode from four samples
when their finding is that a rule exists and nobody has found it.

But one leg is gone and is not being kept quietly: part of the case for 0 was that
the quantity might be machine-dependent and unauthorable. It is not. That removes
an excuse without supplying a value.

Added a tripwire: if the gap is non-zero in most transitions and no rule emerges,
omitting a real quantity stops being caution and becomes a different invention.
The port is wrong by 4-6 units on three of four known transitions and the why now
says so.

Also records as settled: the outgoing ramp is the declared final ramp, my {8,10,10}
against their measured multiset, two independent routes.

2b79c74586 port: black_hold_units 9 -> 0, and not the value that fits best
The Decoder measured the black gap on three transitions: menu->title 0 units,
title->menu 4, EXTRAS->menu 6. Not a constant, and 9 was outside the range
entirely -- wrong for all three by up to a sixth of a second of black the game
does not show.

Did not take the best-fitting value. A uniform 4 minimises total error (6 against
0's 10); that is fitting three samples. 0 has a reason that is not a fit -- it
adds no black the game does not have, the tie-breaker input_during_transition
already uses, and it is measured-correct for one real transition. The error is now
a missing gap of at most 6 units on two transitions rather than an invented one of
up to 9 on all three. Boot artifact unchanged at 0.0009% differing.

Their EXTRAS run vindicates the earlier refusal: B from EXTRAS goes black for two
completely empty frames, so the two-line change I declined would have been wrong
for two of three transitions.

Also: the declared final ramp is confirmed from my side (title 8, main_menu 10,
extras 10 -- their exact multiset), needing no constant. And exit_ramp_units
defaults to 24.0, the number HANDOFF told me to author and I refused, on a branch
that cannot execute: 866 keyframes across 16 screens, 0 untimed.

And origin/main is the stale era -- verified 0 145 left-right, tip 2026-08-29,
still carrying the pre-fix association. The per-iteration merge has been a no-op
for days, its 'Already up to date' reading as 'I am current' while meaning 'main
has nothing'.

ed14722996 port: check-all excused two failing rows with a measurably false reason
The suite reported '2 DIFFERS, allowed: the pin is not on main, so this compares
two decoder eras', and I had quoted that for several iterations without testing
it. Built sylpheed-cli at formats-pin-2026-08-30 and at workspace HEAD and
rendered through both: title, title_jp and main_menu come out 0 pixels different,
despite 508 lines of difference in ui_layout.rs. The eras are not the cause, and
the allowance was excusing a real signal with a wrong explanation.

A second defect in the same eight lines: the expiry tested formats-pin-2026-08-29d
while Cargo.toml pins formats-pin-2026-08-30, so it would have expired on a tag
this tree does not use.

The real reasons are per-screen and already documented: title is the ptloop sweep
phase residual, title_jp is the --pose=rest sparkle handling -- where the port's
shipped pose scores +0.9994 against the game to the reference's +0.8727, so the
port is closer to the game on the row the script calls a disagreement.

Replaced with a named set: title and title_jp by name, any other DIFFERS fails.
A count cannot notice a different screen drifting while the total stays at two.
Controlled both directions -- passes on the known pair, fails on main_menu or
extras. The pin reminder now reads the tag out of Cargo.toml so it cannot drift.

1facce5ddd port: check-all passes end to end; A and B transitions are not the same shape
First end-to-end pass I have actually seen: all six asserting checks ok, oracle
captures at 0.00-0.35%, verify-screen's 2 DIFFERS allowed for its stated reason.
My two earlier attempts produced nothing -- one killed by my own timeout with
block-buffered output, one wedged by the ffmpeg hang -- while I reported 'still
two lines, both ok' for three iterations. I was treating absence of output as
patience.

Their discriminating test holds, prediction written down first: incoming build 4
gives an 8-frame decay, build 5 a 5-frame one against my predicted 6. Their tell
reproduces from my export independently -- main_menu settled is [64], title's
opening pair is [255,64], composite [64,255,64], and no single element produces
it.

The consequence neither of us predicted: A title->menu is sequential with a real
~5-frame black interval, B menu->title has NO black interval -- the incoming title
draws at frame 34, before the outgoing quad ramps at 40. boot.gd applies
black_hold uniformly, so the port inserts ~9 units of black on B that the game
does not have.

Not changed. One run of one transition is exactly the generalisation they just
named as the error under two of their own wrong readings, and their second caution
is that the A figure may be a load rather than a designed hold. Recorded as a
known, stated divergence with a BLOCKED ask.

9ab1f59195 port: check-all hung for an hour on an ffmpeg that had already finished its work
check-all sat on two lines of output for over an hour. The cause was the 5.1 bed
in check-capture-controls: ffmpeg completes the filter graph and then never exits.
Diagnosed rather than guessed -- the output reaches 4604262 bytes, exactly 8.0 s
of 5.1ch/16-bit/48kHz, the full intended length, with the artifact correct on disk
while the process hangs.

Three formulations all hang and all produce byte-identical output: the original,
one with -t 8 bounding the output, and one with explicit asplit feeding each atrim
(the textbook fix for multi-use of a single input). So it is not the split, not
the output stage, and the artifact is not in doubt.

Worse than the hang: it leaks. An orphaned ffmpeg from this script's earlier aloop
form was still running after 9.5 hours, burning CPU across runs nobody was
watching. boot.gd's header already names the shape -- a job that waits forever
reads as a job still working.

Bounded with timeout, and the ARTIFACT is now checked rather than the exit code:
the bed's duration must be 8 s or the sweep refuses to score itself. That is the
better test regardless of the hang -- an exit code says ffmpeg thought it was
done, the file says what it wrote. The step now completes in 99 s and the sweep
matches its specification.

03457c42e3 port: withdraw the 18-vs-19 agreement -- it compared two different intervals
The Decoder declined to let their measurement confirm my black_hold_units, and
they are right. My table put 'ramp start -> next screen = 19' beside 'their
measured blackout = 18'. Theirs runs content-start -> fully-black; mine runs
ramp-start -> next screen. Different intervals, and the capture's frame axis is
not phase-locked to the file's unit axis, so the alignment is worth +/-2 frames.

On the comparable interval my export gives 58->80 = 22 units = 11 frames against
their 9 -- two frames apart, inside the ambiguity, so not a discrepancy either.
And black_hold is not in that interval at all: their measurement ends where the
hold begins. It neither confirms nor refutes the 9.

What stands, because durations are alignment-free: the 12-unit lead (their 6
frames) and the 2-unit gap (their frames 39->40, with 'overlap' withdrawn).

9 now sits as authored-and-consistent, not confirmed-by-measurement.

Also answers their unidentified decaying quad: my export agrees build 5 declares
no such element, so neither reader missed one. Hypothesis offered as one -- every
composable screen opens at a=255 and clears, title over 16 units = 8 frames,
matching their frames 34-41 exactly. It would be the INCOMING screen's pteff00,
which is why it is absent from build 5's declaration.

1df492208b port: their withdrawn 14-unit hold does not touch my authored 9 -- it supports it
Two warnings. The first does not reach me: nothing is authored from
screen-transitions.md's 0.87/0.97/4.08 s spans, and nothing in this port reads
keyframe times outside the crate -- their stale fade_quads.py failure mode cannot
occur here by construction.

The second is about black_hold_units: 9. Testing their structural claim on my
export: pteff00 on main_menu is [0:a255 12:a0 70:a0 80:a255], rising to black over
70->80, while content fade-outs start at 58-60. That is 12 units of lead, exactly
six frames at 30 Hz, matching their measurement off the running game -- disc and
capture agreeing by independent routes. They say the two overlap; mine has a
2-unit gap, one frame, inside their stated resolution.

The arithmetic: quad ramp 10 units + my authored 9 = 19 units = 0.317 s against
their measured blackout of 18 units = 0.30 s. One unit apart, inside their own
resolution. The measurement that withdrew the 14 supports my 9.

It survived because I declined to author the 14 when the arithmetic was available
and fit -- I wrote that it was arithmetic rather than a measurement and left the
value where it had been measured. Had I adopted the composition I would now carry
24 units against a measured 18, which is the dead black they are warning about.

Not adjusting 9; one transition, one run, +/-1 frame.

2a338ad2e2 port: audit my tree for the disc-wide ordinal foot-gun -- no exposure, verified
The Decoder found the ordinal/entry divergence is disc-wide (21 of 24 archives, 18
at ordinal 0) and that GP_TITLE is the mildest case on the disc, the only archive
whose first ten ordinals are the identity. That is luck, not design.

No exposure here, checked: the four archives they flag appear in flow.json with no
numbers at all, screen_names.json already says LOCATED BY ENTRY INDEX, and every
tool of mine passes --all.

Verified the high ordinals where GP_TITLE's identity would break first, since my
export addresses 13 and 14: publisher twins 10 vs 13 at RMSE 3.06, developer twins
11 vs 14 at 4.33, against a control of 47.91 for two genuinely different screens.
The addressing lands where HANDOFF says the entries are, and the control shows a
mismatch would have been caught.

The constraint is recorded for whoever exports those four archives; the absence of
exposure is a fact about what I have exported, not a property of the tooling.

Also corrects my own wording: I called ptlogo_all_eff a '50% glow'. What is
measured is the plateau -- that it is a glow rests on kind 0x3000 and a 200% scale
that nobody has put in front of the running game. The mid-ramp correction stands
on the numbers alone.

1c065685ce port: no case in the export separates width from mid-ramp, and my first answer was a bug
Width and mid-ramp predicted identically across my five capture-backed screens, so
I looked for a screen among the sixteen that breaks the tie -- either would turn
'confounded' into a minimal capture request.

The first run said title_jp was exactly that: window 46 with one mid-ramp element,
and I have the Decoder's capture of it. Wrong. The element is ptlogo_all_eff,
[0:a0 76:a0 112:a127 246:a127 258:a0], which HOLDS 127 from t=112 to t=246. My
test was 0<alpha<255, which counts any legitimately semi-transparent element as
mid-ramp, when the mechanism is about being caught in transition.

Corrected to: t falls strictly inside a segment whose endpoints differ. title_jp
goes to 0, main_menu and extras from 2 to 1 (pteff10 was a false positive
alongside the genuine ptmsg). The 5/5 result survives -- non-zero exactly where
the settle pose loses.

No separating case exists anywhere in the export: no wide window with a mid-ramp
element, no narrow window without one. The confound is structural across the whole
corpus, so no capture would separate the hypotheses from my side. They may be the
same phenomenon twice -- a narrow window is by construction one that closes while
things are still moving.

0a939f1c9a port: verify my own indexing against the ordinal foot-gun that voided three of theirs
The Decoder retracted three claims: screen render --build N takes a build ordinal,
screen list maps [10] to entry 12, and the splashes are entries 10 and 11 -- so
their splash rows rendered the loading screens against splash captures. My own
HANDOFF entry had warned that this names the splashes as loading screens 'and
everything still validates'.

verify-screen's header claims --all protects me from exactly this, and a comment
claiming protection is what just failed on their side, so I measured it: my
reference for build 10 scores RMSE 8.97 against the publisher splash capture and
build 11 scores 8.77 against the developer one, with a cross-control (publisher
reference vs developer capture) at 48.17 -- 5.4x worse, so the discriminator has
teeth. The addressing is correct and now measured rather than asserted.

Worth the time because these two screens' 0.01% figures are among the strongest
evidence in the corpus and are cited in the rest() adjudication a proposal against
a pinned crate now rests on.

Their retraction confirms 190 and 145. Width and mid-ramp remain perfectly
confounded across every screen either of us has measured; my 5/5 predictor result
stands as a hypothesis about the mechanism, not as evidence over width.

cb326175ee port: my predictor holds 5/5, but the evidence separating it from width does not
The Decoder concluded width does not predict settle-pose quality but my
transient-peak/late-arrival predictor does, on the grounds that the splashes are
narrower than the menu (window 8) and win by 75x.

The predictor holds 5 of 5 on my capture-backed screens: mid-ramp count is 2 on
exactly the two screens where settle loses and 0 on the three where it wins.

But their splash window disagrees with my export by 20x. Recomputed from raw
top-level keyframe times, publisher_logo is [0,15,30,45,235,239,251,255] whose
widest gap is 45->235 = 190; developer_logos gives 145. We agree exactly on title
(76) and main_menu (12), so the divergence is specific to the splashes.

Consequence: the splashes are the WIDEST of my five, not the narrowest, so width
and mid-ramp predict identically and are perfectly confounded across my screens.
The case that separated them evaporates -- my predictor is not established as
better than width by this evidence, which is a different claim from being wrong.

My numbers also make their own census coherent: at window 8 the splashes would sit
in the 40.9% bucket while showing zero mid-ramp elements, a paradox; at 190/145
they sit in the wide bucket where zero is what the census predicts.

adecaef399 port: the settle-instant candidate is not uniformly better -- the menus arrive late
Their symmetry-breaking property is testable on the two screens my earlier table
marked confounded, and it turns up a class where their candidate loses.

ptmsg is [0:a0 44:a0 56:a255 58:a255 64:a0] and main_menu's settle window is
[44,56] with instant 50 -- so the footer is at alpha 127.5, half-drawn, at the
instant their candidate poses everything. Same on extras. The settle instant is
the midpoint of the longest keyframe-free interval, and on both menus that
interval ends exactly as the footer starts to arrive.

Measured with focus absent from both sides so the earlier confound cancels: t=50
gives 0.30% differing, t=58 (the footer's own hold) gives 0.25%.

Small and real. It does not overturn the proposal, which wins 9x-75x where rest()
returns a transient's peak. It identifies a failure mode of its own: an element
arriving after the settle window closes is caught mid-fade. Both poses are
approximations to a settled screen; neither is the settled screen.

Also: my first run asked --time=50 meaning units and got 50 SECONDS, past the end
of everything. Both poses returned RMSE 56.02 / 9.15%, identical to two decimals,
which is what made me look -- two different inputs giving the same output is the
instrument saying it ignored the input.

d113b681be port: score the boot's own end frame against the game -- 0.00% differing
--boot --capture= used to write no file: _finish_boot() was reachable only from
the overlay-quit branch, and the boot quit first because that branch fires when
_overlay_spec.is_empty(), which it is the instant the overlay is raised. Fixed
earlier this session by the _overlay_quit_at guard -- and I never went back to
check what the fix made possible. The P3/P7 artifact has been available for hours
and unused.

The boot running unattended and photographing its own end state: RMSE 12.80,
0.00% differing against live-title-press-a.png. The residual is the known capture
gamma floor.

More useful: verify-capture reaches this frame by a shortcut (--screen=title
--overlay=press_start --time=3.95) rather than by booting, and that shortcut has
been trusted since it was written and never tested against what it stands in for.
It is faithful -- 12.83 / 0.00% against the boot path's 12.80 / 0.00%, agreeing to
0.03 RMSE.

Does not show the intervening sequence is right: it is one frame, the last one.

3a66665f66 port: adjudicate the rest() replacement against the game -- 3 clean wins, 2 confounded
They proposed posing at the screen's settle instant, found their control could not
validate it (a candidate cannot be adjudicated against the incumbent it replaces),
and said the oracle number decides. I had only run it on one screen.

Three screens adjudicate cleanly and all favour the candidate: title 0.21% vs
1.82%, publisher_logo 0.01% vs 0.75%, developer_logos 0.01% vs 0.33%. The settled
figures match verify-capture's independently recorded numbers to the digit.

Two rows are not evidence. My first table had main_menu at 3.29% for the
candidate, losing by 13x -- the opposite direction from everything else, with no
plausible story. --screen= shoots immediately, so that render drew 6 of 16
elements and skipped ptframe1, ptframe2 and ptmsg as transparent at t=9. The same
wrong-frame error as title_jp, caught before publishing only because the
direction made no sense.

Posing them properly needs --menu, which also draws the focus record, while the
rest column draws none. verify-capture's header records main_menu without focus at
2159 px = 0.234%, and my incumbent figure is 0.25% -- so the entire gap on those
two rows is the focus record, not the pose. Marked confounded rather than counted;
a 5-0 was available by not looking.

Does not validate their implementation: I tested the port's settled pose, not
UiBuild::settle_time().

eff5539d33 port: test the Decoder's structural criterion on my census -- it fails my control
Their surviving number needs no threshold: the dwell fallback runs only when no
two adjacent poses are equal, so every pose it returns is un-held by construction.
The obvious move was to replace my 'gone before 60% of the screen' cutoff with how
long the rest pose is held.

It flags ptmsg (the main menu's footer, 2 units of 80) and ptbtn00 (the plate, 2
of 244) alongside the real sparkle (2 of 269). All three sit on a 2-unit plateau,
so hold duration cannot separate them -- and the two it gets wrong are the exact
pair whose absurdity caught my first census.

The criterion does not transfer because on the fallback path nothing is held, so
un-held IS the defect, while on the plateau path the plateau is real and what
distinguishes a footer from a sparkle is where it sits relative to the screen's
end. The screen-span criterion stays.

779191daa4 port: the loading screens are no longer black -- it was the paint order
verify-screen's header has said since P1 that build_12/build_15 render pure black
in both renderers, with an open question whether that was the port's bug or the
decoders' reading of rest. Measured today: max 214.5 on both sides, mean 1.949
port against 1.918 reference. Not blank, and they agree.

It was the paint order. My own earlier measurement had already answered it and I
had not connected them: removing the forced-backdrop pass makes the first element
pgloading_loop5 and the black screen returns. pgloading_eff00 carries layer: null,
layer_source: none -- the only elements in the export with neither a read nor an
implied key -- so its position rests entirely on the occlusion constraint.

The guard stays, with the stale paragraph kept as history. It was right when
written, and a guard that stops firing is the kind that rots out of a tool.

Refutation attempt on the Decoder's census scope: my six transient
ptlogo_back2eff* on title are also GP_TITLE, so if they were fallback fires their
count of four would be wrong. Their claim survives -- all six reach rest by the
plateau path, alpha 255->255 with identical pos and scale, so the fallback never
runs. The two censuses differ in scope, not in fact.

f486aac4b9 port: accept the plateau correction, and census my own rest-transient exposure
The Decoder refuted my refinement: palogo_gamearts_eff/palogo_seta_eff hold a=255
at identical x, y and scale from t=15 to t=30, so that is a genuine plateau,
rest_plateau() handles it, and t=15 is correct for that path. They are not among
their four.

The consequence strengthens the rule rather than retracting it: my rest pose for
them really is the flash's peak, reached by the SOUND path -- so 'a rest render is
not a frame to score against a capture' does not depend on the fallback being
unsound. A plateau can itself be the held peak of a transient, and their census
understates exposure rather than bounding it.

Censused my own tree. The first answer, 28 elements across 12 screens, was wrong:
it counted the screen's exit ramp as the end of visibility, so ptmsg -- the main
menu's own footer -- and ptbtn00, the plate, came back as transients. No control
would have caught that; the arithmetic was right. What caught it was saying what
the number meant physically.

Re-keyed on the screen's span: 31 elements across 8 of 16 screens, all of them
eff/loop sparkles or the two loading screens, with ptmsg and ptbtn00 falling out
on their own. Exposure is twice what the splash finding suggested. None of it
reaches shipped output.

9233ff1e08 port: the rest() flash defect reaches all four splashes I ship; the port survives it
The Decoder censused rest()'s dwell fallback from the file side: 2305 elements
have no plateau, 1697 of those get a visible pose, and in GP_TITLE all four
visible fires are on the splash screens this port ships. Confirmed in my export.

Refinement to their description: they named the [0:a0 15:a255 30:a212 45:a0]
shape, but palogo_gamearts_eff and palogo_seta_eff hold 255 through t=30, so
their fallback lands on the flash PEAK rather than its decay. Same defect, worse
pose.

The port ships the right frame and there is now a number for it. Publisher splash
against the committed oracle capture: timeline (shipped) RMSE 2.17 / 0.01%
differing; --pose=rest 9.05 / 0.75% -- 75x the differing area on a screen I ship.
So the rule added to verify-screen's header after the title_jp mistake
generalises, and is demonstrated against an oracle rather than argued.

What did need fixing: ScreenView logged '(transparent at rest)' for every skipped
element whatever instant it posed, so it said that about palogo_sqex_eff, whose
resting alpha is 212. That is the same rest-versus-posed-instant confusion that
cost a wrong conclusion, pre-printed in the log. It now names the instant.
Controlled both ways: timeline says 'at t=6' and skips the flash, --pose=rest
still says 'at rest' and draws it.

aa51e5af67 port: WITHDRAW the claim that the port drifted away from the game -- wrong frame
The previous entry scored verify-screen's title_jp frame against the oracle and
concluded the port had moved away from the game. That frame is posed --pose=rest,
which the port does not ship. Posed as it runs, the disputed block scores +0.9994
against the reference's +0.8727, and the whole surface +0.9652 against +0.9200 --
holding under gamma compensation and on the English control (+0.9946 vs +0.9560).
The port is closer to the game than the reference on both title screens.

Mechanism: ptlogo_back2eff1 is (0,0)(98,0)(100,255)(102,255)(104,0) -- a 4-unit
sparkle whose rest.t is the peak of its own flash. Six of them stagger across the
logo, so --pose=rest fires every sparkle at once. The 25.6% excess light was real
and was in a frame nobody sees.

verify-screen is not at fault: it poses rest deliberately, so that both renderers
read one decoder and the run is a consistency check. I used a consistency-check
frame for a correctness question. Its header now says its frames must never be
scored against a capture.

A second claim in that entry was also wrong -- both screens draw those layers
under pose=rest; I had compared a --menu timeline log against a verify-screen
rest log and read a mode difference as a screen difference.

verify-capture takes a fifth per-row field, a capture crop, because this capture
is a full display frame with the surface at +0+45 while the others are
pre-cropped. With it title_jp reads RMSE 20.91 / 1.04%, beside title's 14.16 /
0.21%. The row prints 'no capture' until their branch merges.

05c4b58151 port: the JP title capture adjudicates title_jp, and it goes against the port
The Decoder captured the Japanese title at rest (310bf86) without comparing it to
either renderer, keeping my diff independent.

Alignment recovered, not inherited: row/column profile correlation with the
English pair as control gives (0,0) for the control and dy=-45 for the JP frame --
their stated offset, measured. My first look said 'no letterbox, content spans all
720 rows', which was true and irrelevant.

The instrument is fair: on a control strip where both renderers agree they tie
(r 0.9751 vs 0.9756). In the disputed 350x396 block at (405,74) the REFERENCE is
closer -- r +0.8727 against the port's +0.7462 -- and the verdict is stable under
gamma compensation at both measured title gammas. The port puts light on 25.6% of
the block the capture does not have, against the reference's 15.9%.

This is the opposite of what I expected: the burst the Decoder describes IS
there, and the port draws more of it than the game does. A qualitative match on
'is the effect present' was about to stand in for a measurement of how much.

Not settled: which change did it. Both render at rest t=10 so the settle window is
not in play; four commits touched that path and I have not bisected them.

title_jp's DIFFERS is now known to be the port's -- the first baseline row whose
direction has been established against a capture.

81352459e3 port: verify-screen was nondeterministic; pin the pulse phase in the harness
Running the full set after the plate fix, press_start returned over3 5021, 8919,
5021 on three identical runs. The plate's looping focus record takes its phase
from time_units, which free-runs, so the captured frame lands wherever the grab
fell -- while the reference renderer cannot pulse at all.

The port is not the thing that is wrong: the pulse is measured and a thing that
pulses does not stop because the screen arrived. ScreenView.loop_phase_units pins
it, negative means free-running and stays the default everywhere, and only the
harness passes --loop-phase=0.

Controlled: pinned, 3 runs identical; free-running, 3 of 4 identical and one
different. That 3-of-4 is why it survived -- it looks deterministic most of the
time, and without the negative control a no-op flag would have been
indistinguishable from a fix.

With the phase pinned press_start reads max 1 / over3 0 OK -- the recorded
baseline exactly. Fifteen of sixteen rows now match.

The sixteenth, title_jp, has genuinely drifted: 155/20498 -> 233/61208,
deterministic, on the Godot side, localized to one 350x396 block at (405,74).
There is no capture of the Japanese title, so I can say the renderers moved apart
but not which moved. Recorded as an ask, not resolved.

7dc5117a09 port: the PRESS A plate comes back after B, and it did not here
The Decoder measured that after B from the menu the plate is re-drawn (daf8f47).
The port landed on a BARE title: _menu_arrive drops the overlay -- correct, the
plate goes with the screen it was measured on -- but nothing put it back, since
_overlay_spec is cleared the instant the overlay is raised and only the boot
sequence ever set it. Confirmed by running it: ten title elements, no ptbtn00.

_rearm_overlay_for reads the declaration out of authored/flow.json's boot step
for that screen rather than naming press_start, so the plate returns by the same
path and shared clock as on boot, with NO new constant. Controlled both ways:
cancel raises it, entering EXTRAS (no overlay declared) raises nothing.

Script steps now carry an elapsed timestamp, without which the port's own press
latency could not be compared to a measured one. With it: B at 1.01 s, title at
1.37 s = 0.36 s, against their measured <= 0.4 s -- nothing was fitted to that.

The plate's RETURN time does not agree: 4.33 s here against their 7.3 s to pulse,
of which up to 2 s is pulse-detection phase. Not adjusted -- an authored delay in
this same block was already refuted once. Recorded as an ask.

auto_repeat and title/on_cancel upgraded to MEASURED on their run.

7ecbed1d09 port: audit BLOCKED's five blocking rows -- all answered, and ask 2's action is stale
Rows 1 and 2 were still labelled '(P3, blocking)' while P3-P7 have all shipped.
Audited all five against HANDOFF and checked whether the port ACTED on each
answer: splash by entry index (publisher_logo 10/13 exported), focus ring
ptbtneff01 drawn, rotation about pos+pivot, gamma floor in verify-capture's
header. Four struck, one (rotation) still a human decision.

HANDOFF ask 2 tells the port to author a ~24-unit fade constant. That is stale:
the corrected record layout leaves no untimed keyframe, and measuring what the
file carries shows the black quad ramping 0->255 over TEN units. Authoring 24 on
top of it would run the fade 2.4x too long. The mechanism ask 2 describes is
confirmed in the file; its number is not.

Offered as a hypothesis, not a finding: in-file ramp 10 + measured hold 10-14 =
20-24 units = 0.33-0.40 s, bracketing the measured 0.4 s at the top -- so the
0.4 s may be ramp + hold, needing no constant at all.

Also surfaces a disagreement in my own tree: black_hold_units 9 (0.15 s) sits
below HANDOFF's measured 0.17-0.23 s plateau. Not changed; recorded as an ask.

7099b5debd port: on_cancel half measured, and a MEASURED stamp removed from the other half
The Decoder measured B on the main menu -> title (86a8ce7): delivery-confirmed,
<= 0.4 s, no loading screen. main_menu/on_cancel moves from 'likely but UNPROVEN'
to MEASURED -- and it is the LATENCY that settles it, not the destination: my own
why had named the confound that the title also auto-returns after ~8-10 s idle,
and 0.4 s is twenty times faster than that.

The other half is a fault in my tree. title/on_cancel_why read 'MEASURED,
HANDOFF Q5'; the source's evidence cell for that clause reads 'none'. HANDOFF Q5
prefixes a six-clause row with one **measured** and my authored tree copied the
word. The value stays null either way, so no pixel moves -- what is removed is a
false provenance.

Auditing the rest of that row rather than only the clause I was handed: the
up/down cell is ALSO empty. It splits -- one-item-per-press is carried indirectly
by the wrap montage's count, no-auto-repeat is not. The port already behaved this
way without stating it (edge-triggered _input), so navigation.auto_repeat is now
explicit and marked a choice.

34 MEASURED stamps audited; six cite a HANDOFF row alone, one of which was wrong.

6f161ab981 port: confirm no screen of mine carries a .tbm, and guard verify-screen anyway
The Decoder found that sylpheed-cli screen render silently omits the background
of any .tbm-bearing build, and stated that none of my screens has one. That is a
claim about my tree and it decides whether my regression baseline is sound, so I
tested it: zero .tbm across all 16 builds in my manifest -- wider than the five
they said. Both controls fired (GP_TUTORIAL build 0 -> pubase.tbm; GP_TITLE
build 5 -> none); my first attempt's control printed nothing and I nearly read
that as agreement.

verify-screen now names the omission on any .tbm-bearing row. It cannot fire on
a screen I ship -- which is how a guard goes dead -- so its expression is
controlled directly in both directions. No verdict or bar changes.

Regression unchanged: title max 6 / over3 790, main_menu max 4 / over3 0.

Their identification (reading TUTORIAL off the framebuffer) and my edge
correlation (run before their message, blind to the text) agree on GP_TUTORIAL
build 0 from no shared assumption.

They reached a submenu and could not identify it: intensity correlation cannot
discriminate when the candidates are near-blank, which is what the .tbm hypothesis
predicts. Their capture is 99.999% non-black -- a full-screen background our
renderer omits -- and an additive background swamps intensity but not edges.

Control first: edge correlation against my own title capture over seven GP_TITLE
builds picks build 4 at +0.2792, 1.4x over second and 7.6x over third.

Result: GP_TUTORIAL build 0 at +0.4962, build 1 at +0.3137, best GP_SAVE_LOAD at
+0.0713. Winning r higher than the control's and margin better; both TUTORIAL
builds 4-7x above every SAVE_LOAD build. Independently plausible -- flow.json has
ptbtn03 = TUTORIAL -> TUTORIAL_MENU, not a GP_TITLE build.

The ARCHIVE is identified with a large margin; WHICH BUILD is not -- 1.58x is the
same order as the control's 1.4x and the two are variants of one screen.

Every asserting check passes and the oracle rows are at the tone floor:
title_plate 0.00%, both splashes 0.01%, up to title_band 0.35% against its own
oracle-to-oracle gap. The P5 walk runs and ends on the title.

The refutation attempt was of a claim I had already used: that ADV.wmv carries one
audio stream and it is WMA Pro 5.1, which reframed the whole voice question.
ffprobe confirms it exactly -- one stream, wmapro, 6 channels, 5.1.

And I had built on it for a week without running it. The positional weights, the
presentation: all change, the refusal to apply the assignment when byte sizes did
not fit -- all rest on that reframing, verifiable in one command against a file I
have had throughout. I audited the byte sizes scrupulously because they were the
identifier I could test, and never checked the sentence the identifier served.

A premise so foundational that everything downstream got audited and the premise
did not. The scrutiny went to the parts that moved.

Also records what is still authored rather than measured: four values, each
marked at the value.

769ac9a2c7 port: a refuted-claim register, enforced by check-all
The Decoder's audit of their own corpus found four refuted claims standing --
including one they had corrected to me, agreed with, and written a METHOD entry
about, without landing it for a full iteration. A hand audit finds what is there
on the day it runs; it does not stop the next one.

check-claims is a register: every occurrence of a refuted claim must carry an
explicit [refuted] sentinel within 400 characters. It found four more unmarked
occurrences than my manual pass had, including one in authored/audio.json.

The marker is a sentinel rather than a keyword because the first version's every
failure was a quotation inside a correction whose wording lacked the keyword. The
temptation was to widen the window until they passed -- tuning a threshold until
the answer comes out right, in the tool built to catch that. 21 quotations marked
by hand; proved it fails by removing one.

Also fixes the Decoder's other finding in my corpus: BLOCKED's voice row had a
struck heading with three sentences below still asserting in the present tense.

2c62f6e497 port: grep the corpus for the claim -- one refuted sentence was still shipping
Applying the Decoder's rule to my own corpus, on four claims refuted this
fortnight. Two were properly marked. Two were not.

The exported why still told readers the dropped chunk 'IS understood: the TAIL of
the kept stream' -- an interpretation refuted when the resolver turned out to
start 238 packets inside the first stream, so what matched end-flush was a
start-truncated simultaneous stream. It was wrong twice over: S00A's dropped
chunk is the SILENT one, so the sentence described a case that was not present --
the second template-message-true-only-for-one-case defect in this file, which
suggests the first fix taught me nothing general.

'The port's boot is known too fast on both' was still standing unmarked. I wrote
the withdrawal as a new section and left the original untouched, so a reader
arriving there first got the dead answer. Annotated in place.

One false positive: BLOCKED matched inside my own correction, which quotes the
refuted claim to name it. Naming a refuted sentence keeps it greppable, which is
the price of not deleting it, so the audit needs a read of every hit.

wrong window, 0 with the measured window. The old window kept part of the quiet
intro; the measured one excludes intro and fade both. Wrap continuity is

Also fixes a stale why that reached the manifest for two days: corrections went
into loop_end_why and loop_start_why while loop_why, the field the exporter

My first check of that fix reported the stale text still present, because the

500924be5c port: duration confirmed at 0.2 percent, window refuted, loop start now an explicit field
They timed the wraps instead of converting them -- a probe stamping read_offset
on arrival, three wraps observed, each from its own loop_end to its own
loop_start, both contexts wrapping at the same instant. Cycle 61.81 s against the
61.93 authored here: 0.2 percent, from a wall clock between decoder events versus
an autocorrelation that never touched the wave.

The window is wrong: loop_start is 11.6 percent into the stream, about ten
seconds, so this export has the right duration over the wrong window -- replaying
the intro every cycle and omitting the tail the game plays.

Not re-cut, on their instruction: the exact start is unmeasured and linearity is
refuted by a 4.4 percent rate variation within one stream. But loop_end_s alone
silently asserted a start of zero, so the entry gains loop_start_s, authored as
0.0 and flagged wrong, with -ss applied before -t so the pair is (start,
duration). Proved before it is needed: loop_start_s=10 yields -ss 10 -t 61.93 and
a 61.930 s output. Restored to 0.0, export byte-unchanged.

My smooth-join check gains a use I could not have anticipated: it explains why a
wrong ten-second window went unheard, because a cut near a zero crossing is
smooth wherever it falls.

ffe0280679 port: the loop is a runtime field, the readings conflict, the port keeps 61.93
loop_start/loop_end live in the XMA decoder context and Xenia logs them without a
patch. Converted they imply roughly [10 s, 72 s] against the [0.25, 57.18] their
audio tracking gave. Neither withdrawn. Two of their own predictions were refuted
by the data -- loop_start is 11.6% in, not ~0, and a linear bits-to-seconds
conversion gives 62.34 and 63.29 s for two stems that must be sample-synchronous.

The port KEEPS loop_end_s: 61.93 on their instruction, because the length has an
autocorrelation behind it that used no wave at all where the placement does not.

Adds one check neither instrument ran: over 126.5 s the wrap shows a max
adjacent-sample step of 212 and 208 against a 99.9th percentile of 3737, so the
join is not a click. Explicitly NOT support for 61.93 over [10,72] -- a cut near a
zero crossing is smooth wherever it falls.

Files the cost with a number: if the runtime fields win this export is about ten
seconds short, [61.93, 72] being content the game plays and we omit.

04a143d89f port: independently confirm the 1.5 MB cap separates the two sets exactly
Their census settles the population at 25 three-chunk regions, confirming my
count, and corrects their own claim twice: multichannel-specificity holds (17 of
17 changed are three-chunk), but 'all three-chunk regions were broken' is false --
8 of 25 were already fine.

Measured every three-chunk region's span myself: the 8 unaffected run 71680 ..
1400832 B, the 17 affected run 2023424 .. 6516736 B. The cap separates them
exactly with a 622592 B gap between the sets, so this confirms the MECHANISM --
a byte-size threshold -- not just the list of names.

My first run reported 17 contradictions: every span read 0 B because awk took the
trailing 'B' rather than the number. Uniform, consistent and entirely wrong, and
it would have looked strong because the failure fell along the line under test. A
broken extractor produces a pattern shaped by the question. What saved it was the
8 confirming rows reading 0 B too -- visible only by reading the half that agrees
as carefully as the half that does not.

1cae35b43a port: the dead-press check was passing by luck -- diagnosed and fixed
Two iterations ago verify-menu-audio's bit-identity assertion began failing and I
filed three suspects in the port. It is none of them. Three IDENTICAL invocations
give two outcomes, 1.207438 s and 1.300317 s, differing by exactly 4096 samples --
one mixing buffer. The recording quantises to whole buffers and a one-buffer shift
moves the length and alignment of everything in it.

The premise -- cross-run bit-determinism -- was never guaranteed. It held while
timing sat away from a buffer boundary, and a larger export moved it onto one. A
test that passes by luck reports the luck running out as a regression in the code,
which is what it did: two iterations of suspects, and the port was never involved.

The fix keeps exact equality and no threshold, allowing the comparison to slide by
whole buffers -- the one degree of freedom the recorder has. Proved it can still
fail: ctrl against walk differs at every alignment.

Distinct from the earlier entries: this check ran and answered the right question,
resting on a property of the environment nothing verified. State what an assertion
assumes about the machine, not only what it checks.

93b823eedf port: the menu bed loops at 61.93 s -- my 3.4 s seam was ours, not the game's
Measured on 240 s parked on the real menu: no seam at all (zero runs >=0.3 s
below median-18 dB in 232 s), and the loop is at 61.93 s, not the summed wave's
87.744 s length. Two instruments agree -- top correlation lag 61.909 s with
r=-0.009 at 87.750, and slice location showing playback wrap at 61.93 three
times. The final ~25.8 s, the fade-out and trailing silence, is never played.

This port had authored loop: restart, measured the resulting 3.4 s of
near-silence off its own Master bus, and reported it as the price of the missing
loop point -- in BLOCKED and in a message to the Decoder. The measurement was
correct and the attribution was wrong. Second time this fortnight I have measured
something real and assigned it to the wrong side.

Godot loops whole files, so the loop region has to BE the file: BgmSpec gains
loop_end_s and the bed is trimmed to 61.930 s. Verified over 131 s on the port's
own bus -- 5 near-silent windows, no run >=0.2 s, against 36 windows and 3.4 s.

Also records their withdrawal of '8 of 10 three-chunk regions': that audit file
was truncated mid-list with no summary line, so the multichannel-specificity
claim is unsupported and my 25 stands.

478e9967e1 port: external ground truth for all 25 three-chunk regions -- none truncated
The Decoder has no external check on the regions beyond ADV. One reference owes
nothing to their crate: each movie's own duration from its WMV. A start-truncated
stream must decode shorter than its movie -- ADV's was 38% short before the fix.

Dumped every region and decoded every chunk: 25 three-chunk regions, 75 chunks, 0
more than 5% short, largest deviation 1.78%. No region is still truncated, and
the reference is genuinely external.

Flags a population discrepancy: their page says 8 of 10 three-chunk regions start
mid-stream; I find 25 three-chunk regions on this disc. Reported, not resolved.

My first run reported '0 of 13' and there were 25 -- cargo run inside a while
read loop consumes stdin, so every second movie was eaten and the covered set was
positions 1,3,5,7... The result was correct for what it measured and the
population was half what the sentence implied. That is the truncated-log trap
arriving in my own shell loop; I caught it only by comparing against a count from
one command earlier.

73125074c6 port: apply the measured positional weights, keyed by byte size
ADV's three chunks map onto the Decoder's contexts exactly, each a declared
byte_size plus the 60-byte RIFF header. authored/audio.json gains
voice.stream_weights keyed by SIZE, and the exporter weights only when every kept
stream matches, falling back to the divisor otherwise.

The key is the check: two weeks ago these same sizes did not fit the region the
resolver returned, which is how the 238-packet late start was found. Applied
positionally the weights would have gone onto the wrong streams silently. S00A
matches nothing and keeps the divisor. ADV mixes at 0.4142/0.2929/0.2929, -2.87.

Unlooked-for confirmation: the filter folds chunks 0 and 2 from two live channels
and chunk 1 from one, found independently by live_channels, matching their claim
that ctx1 is the only stream with a silent channel.

Also files an UNEXPLAINED regression: verify-menu-audio's dead-press check now
reports DIFFER across three runs, diverging at 0.085 s with different durations.
Not diagnosed, not the voice change, and left failing rather than silenced. The
check's premise is cross-run bit-determinism, which is what made it strong and
also what makes it brittle.

2712efe2f2 port: move to formats-pin-2026-08-30 -- the voice export is complete
The late start was a second condition on the start filter, end - s < 1_500_000,
only within one bank. ADV's predecessor trailer sits 3618816 B before end, so it
was rejected and start fell back to anchor, a TOC offset rather than a stream
boundary -- which is why it hit regions over 1.5 MB and never single-stream ones.

ADV region 3114352 -> 3618816 B, streams 2 of 3 -> 3 of 3, complete, dropping
zero chunks. S00A 1 of 3 -> 2 of 3 with the third digitally silent. The runtime
no longer prints an incomplete line for either.

Also fixes the warning crying wolf: S00A still read KNOWN INCOMPLETE over a
93.694 s stream of exact zeroes. Exported gains content_waves and the warning,
console line and manifest field all key on kept < content rather than kept <
present. Second time in two iterations this warning was wrong in the cautious
direction -- over-warning is what makes the next real warning unreadable.

S00A is a second movie in the predicted direction: kept went 1 -> 2 because a
chunk that was a different duration now matches at 93.694 s. Not independent
ground truth, but a different asset and the outcome was predicted first.

90ea61b472 port: the runtime now says what the voice export is missing, at the moment it plays it
The manifest has carried the gap for weeks and the runtime printed '+ voice ADV'
and nothing else. A reader of manifest.json gets a paragraph; a person LISTENING
gets clean dialogue and no way to learn a stream is absent. NEW GAME already
announces the screens it jumps over; audio had no equivalent.

ManifestAudio gains  -- one line naming what is KNOWN missing, absent
meaning nothing is known rather than nothing is wrong -- and MenuAudio carries it
so _play_video can print it. Verified on the boot's ADV and P7's S00A.

The first version of the message was FALSE for one of the two assets: it said
'one is a start-truncated stream', which is ADV's story, where S00A's dropped
chunks are digitally silent. Caught by reading the output for both, which I
nearly skipped because the ADV line was obviously right. Now states the counts
and points at the entry's why.

A message generated once from a template but true only for the case it was
written against is harder to see than a wrong number -- the sentence is
well-formed and confident in both places.

9739b90266 port: the resolver starts late, and my 'duplicate tail' was a real stream
My refusal to apply their weights found a defect in their decoder:
resolve_movie_voice_region starts 238 packets (487424 B) inside ctx0 for ADV, and
8 of 10 three-chunk regions start mid-stream disc-wide.

That re-reads one of my own measurements without touching it. I had the leading
chunk as 'the TAIL of the kept stream' at r=0.998, lag flush against the end, and
dropped it as a duplicate. If the streams are simultaneous and the region starts
238 packets into ctx0, the surviving fragment is ctx0's later 62%, which aligns
flush against the end -- exactly what I measured. Same number, opposite meaning:
a start-truncated simultaneous stream, not a duplicate. The port drops a real one.

I suspected the instrument first, since they had just shown envelope correlation
saturating at 0.86-0.95 across stream/channel pairs. Tested on the dialogue: r =
1.0000 at zero offset, -0.08..+0.08 elsewhere. It localises sharply; their
saturation is concurrent streams at zero lag, a different regime. So the tool was
sound and the error was entirely in the inference.

Not fixed: including chunk 0 needs their corrected span (they say do not extend
blind -- only ADV's clip is known) or an alignment decision I would be inventing,
since the chunk is missing its head.

46eeecf658 port: their stream assignment does not fit my region -- weights not applied
The assignment is settled by byte_size: ctx0 -> FL/FR, ctx1 -> FC, ctx2 -> BL/BR.
Applying it needs their contexts to be my chunks and they are not. Their three
sum to 3584000 B; my whole resolved ADV voice region is 3114352 B, 469648 B
smaller than the contexts that must fit inside it. My region yields three chunks,
one an 84.553 s / 806972 B tail matching none of their sizes, leaving two real
streams at 2307380 B -- and no pair of their contexts matches it (closest 2289664,
out by 17716).

So the weights are NOT applied: assigning positions on a byte-size match that does
not hold is worse than divide-by-count, and their own figures put a swapped
assignment at 11.76 dB wrong.

Not claiming their assignment is wrong -- theirs is a probe of the running
decoder, mine is resolve_movie_voice_region's byte range off the disc, and one of
the two spans is not what the other thinks it is. That is a decode question.

Takes the parts that stand alone: one mixer gain of 0.600 for bed and voice (not
baked in), and their two failed instruments -- envelope correlation saturating at
0.86-0.95 for every pair because the channels share dialogue timing, which is the
instrument I have leaned on all fortnight.

#4 answered: ADV.wmv carries ONE audio stream and it is WMA Pro 5.1, not XMA, so
the movie's own track is the bed and the three streams are additional. Solving
capture = 0.600 x movie + residual gives three residual signals at three
positions, with LFE reproducing to -115.73 dBFS -- where nothing is added the
decoders agree exactly, so the rest is added content.

presentation: all keeps every equal-length non-silent survivor -- ADV 2 of 3,
S00A 1 of 3 -- and the warning now keys on kept < present rather than on more
than one existing.

A unity sum was tried first and check refused it at +2.62 dBFS. The BGM stems
precedent did not transfer: those are stems of one signal, these are positions in
a field whose downmix weights sum to one whatever the assignment. Dividing by the
count preserves the total and claims nothing about placement; ADV lands at -3.1.

That is the OPPOSITE of the two divisor bugs already in this file, where a silent
input sat in the divisor. Divide-by-N is not right or wrong in itself.

Also carries their census correction: the ALSA permutation does not apply, the
map is the identity, and the '82% silent' channel was LFE.

f7eac0e676 port: rendered pulse counted in their units; #4 refutes the voice value without fixing it
With their predicate the port's render is comparable to their capture for the
first time: pulse minimum 805 against their 714, peak 1420 against 1520, both far
above the 154 floor. So 'never goes off' holds in the port's own render.

My pulse is 24% shallower and I am NOT tuning it -- their own limit says the
counter is thresholded pixels, so a depth measured this way is a fact about the
threshold as much as the glow. The port draws the declared ramp.

#4: 148 s of the game's output, five of six channels distinct, no channel a copy,
largest pairwise correlation 0.70 between FL and FR. So presentation: loudest --
keeping one stream -- is refuted by what the game PLAYS, not merely suspected.

Stays unfixed on their instruction: the stream-to-channel mapping is not run, and
swapping one authored guess for another is worse than a guess that is labelled.
Also records that '6 channels' is Xenia's hardcoded default, not evidence of 5.1.

I challenged 159/714/1520 as unreproducible; my region counts were 3-5x theirs.
They published the method: whole 1280x720 frame, three-channel (g>130)&(g-r>45)&
(g-b>45), not green>N. Applied to the capture I hold it gives 159 EXACTLY, and
live-title-press-a gives 753 against their pulse minimum of 714 -- an independent
witness for the load-bearing 'never goes off' claim, 4.7x against their 4.6x.

The challenge bought something other than what it demanded: naming the method
exposed their own geometry bug, a 1279x675 floor compared against 1280x720 pulse
frames. Replaced with a same-run 154. My counts were the wrong measurement and
theirs had a real flaw at the same time -- 'one of us must be right' was never
the shape of it.

Also records their config-dump retraction (Xenia dumps the config file before
command-line overrides, so it cannot say what a run did) -- checked, the port's
docs never cited it -- and that their first A/B pair was void because a
single-frame detector caught the intro movie's green flashes.

--screen=X animates X but froze an overlaid Y -- my earlier fix overshooting,
replacing a frozen-too-early overlay with a frozen-at-arrival one. The plate
pulse made it visible: oscillating on the boot path, flat here. Now offset, not
pinned: the overlay starts at its settle and takes the main view's delta. Static
path now pulses 95.85 -> 115.41 against the boot's 95.68 -> 115.52; still frames
unaffected and title_plate holds at 0.00%.

Both halves were mine a week apart, and the over-correction was invisible until a
third change gave it something to be wrong about.

Refutation attempt on their pulse floor: 159/714/1520 is NOT reproducible from
the published description. My counts on the same capture are 3-5x theirs at every
threshold, so their region must be a tighter crop; neither region nor threshold
is stated. The RATIO survives robustly -- 1:10.4-10.9 across a wide band,
bracketing their 1:9.6 -- so 'steady base plus pulsing glow' stands, which is all
the port's implementation rests on.

aa6be8e809 port: the plate pulses -- restore the looping record, over the base rather than instead of it
Ask #1 measured: held at the title with no input the plate oscillates ~23 cycles
per window with no decay and NEVER goes off -- floor 159 thresholded pixels,
pulse bottoming at 714. A glow alone cannot do that (0 -> 80 -> 0); a steady base
plus a pulsing glow can, and 714/1520 are base-only and base-plus-glow.

The port already had the base right: ptbtn00's fade to 0 at t=244 is its EXIT
ramp, and while held the base sits at alpha 255. The glow was missing.

The defect was in the renderer, not the entry I deleted on 2026-08-29. _draw
treated a looping record like a focused one -- drawn INSTEAD of the base, which
is right for a focused button and wrong here. I deleted the right thing for the
wrong reason. A looping record now draws OVER the base and the entry is restored.

Rendered: 95.68 base only, 115.52 at peak, period 1.980 s against a declared 120
units = 2.000 s, ratio 0.990. Visible on the boot path; not under --screen
--overlay, where a static overlay poses at its arrival by design.

Authored in UNITS on their instruction, with their three limits verbatim: one
boot, does not distinguish boot from attract title, and 714/1520 is not an alpha
ratio so no duty cycle is inferred.

Seven candidates, six were my matcher (thousands separators, ranges written

The one real defect is the opposite: check-capture's control table and

control whose file is gone so neither can be re-measured. They lost a finding to

Fixed by citing rather than restating.

Ask #2 answered: t=357.7 was never fitted against a PNG. It is a GPU per-draw
vertex capture, four observables at once.

They handed me the discriminator rather than running it, since the fit is against
my renderer. At my t=400, pteff03a computes to 294.9 against their predicted 295,
and my computation reproduces their published t=355 control (980.5/477.7 against
981/478). So the two numbers describe different frames and neither is wrong.

Why they could never match: the leaves free-run at 600 and 720 units (verified
from my export as each leaf's last keyframe) while the top-level clock stops at
settle, so two captures of one settled title share a screen time and not a sweep
phase. A SWEEP POSITION CANNOT DATE A FRAME -- I had been treating my ~400 as a
property of the capture.

Also records their failed refutation of my number: they hypothesised the fit was
minimised by the quad leaving the screen, the same shape as their .tbm control
that could not fail. At t=400 quad B is fully on screen. It survives.

pgloading_ring, scale ramping 0 -> 250 -> 800 -> 1000 with alpha full at t=55 --
an expanding fading ring, visible at scale 140 alpha 143 at the port's own pose
instant near t=44. Withholding it declines to draw SOMETHING.

Still withheld, on the reason already in the file: no oracle capture for a
loading screen and verify-screen's reference draws no leaves, so the content is
unadjudicable. Behaviour unchanged at 59530 px.

The two entries in that list were written to different standards -- ptlogo_eff2
gets four paragraphs working through both readings, pgloading_loop5 got one false
line. The difference is that one was interesting and one was a loading screen.

Also verifies the measurement in the same paragraph: 'max went 155 -> 232 when
drawn' reproduces at 231, differing pixels 20498 -> 58313. The file's numbers
were sound and its reasoning was not, in adjacent sentences.

789e8ab15c port: none of the 80 forced instances has a decoded key; the port's four are oracle checks
Disc-wide: 0 read from the T8aD header, 14 implied, 66 nothing. So the rule has
never been checked against a decoded field because no instance lets both speak.
The port's six are the same pattern: 0 read, 4 implied, 2 nothing.

Records their retraction, which runs against their own interest: 'none of the 18
is evidence' conflated two questions. The rule does not CHANGE the composite on
those 14, but it does get the RIGHT ANSWER there, and implied_layer_key is a
position measured in the running game -- so those are the rule agreeing with the
oracle, its only external corroboration. Four of the 14 are the port's splashes.

My own framing was right about provenance and wrong about weight: I filed an
oracle measurement under 'not the file', which reads weaker when it is stronger.

Closing the thread on my side -- four iterations, and it has stopped being about
the port.

ec5861cec8 port: reconcile the ink figures -- 96.7% of the gap is value-1 pixels
Their 49771 is exact RGBA inequality, not a threshold, so it belongs against my
59530 rather than my 48368 -- they corrected that before I could match the
convenient pair. At >1 we agree to 325 px (0.67%).

Checked here: my value-exactly-1 population is 11162 px and the gap above >1 is
325, so 9434 of the 9759-px gap (96.7%) is value-1 pixels. Their claim holds
structurally.

Carries two conventions: >0 is not portable between renderers on a mostly-dark
frame and >1 is, so a cross-renderer ink figure must name its threshold; and the
without-the-rule zero is threshold-insensitive in both renderers.

One refinement on their 18 confirmations: for the port's four, 'has its own key'
means palogo_eff0's IMPLIED key -- the crate's measured per-name entry, not file
data. So those are 'another measurement already settles it', not 'the file
settles it' -- the distinction their own page insists on for pteff00.

075c81792d port: second witness for the pixel-cost claim, in Godot
The Decoder rendered the 62 deciding builds twice and found changed pixels equal
the composite's entire ink on all 38 .prm deciders, with build_12/15 at 49771 px.
Checked in Godot, which shares no code with their compose: with the rule 59530 px
(>0) / 48368 (>1), WITHOUT it exactly 0 at both thresholds.

So the strong form holds -- removing the rule does not dim the screen, it takes
the ink to zero -- and this is a real second witness, unlike last iteration's
re-run of their own instrument. Their 49771 sits 2.9% above my >1 count: a
threshold convention on a mostly-dark frame, recorded so nobody later reconciles
two figures that were never counting the same pixels.

Method: applied THEIR fallback (sprite key, else implied, else u32::MAX) to the
export's element list and swapped only paint_order on one screen, so the renderer
and every other input are identical and the order is the only variable.

Also records their point 4 -- the 24 .tbm deciders measured zero because compose
draws no .tbm pixels at all, a control that could not fail. Fourteenth instance of
the shape, and the first caught by the other agent using the frame.

fe97c583d4 port: re-run the Decoder's necessity census -- 80/62/18 reproduces exactly
They published the instrument so it could be re-run rather than trusted. Ran it
from a worktree at their branch across all 33 archives: 80 forced, 62 decided, 18
agreed, 38 .prm / 24 .tbm, all 62 keyless. Every figure exact.

Names the limit: I ran THEIR code, so a fault in the instrument reproduces for me
too -- one measurement executed twice, not two measurements. The independent
evidence is my own export-side removal of the post-pass, which is different code
in a different language and agreed on the six GP_TITLE instances. So GP_TITLE has
two witnesses and the other 74 have one.

Also notes the example defaults to GP_TITLE and reports 6 unless given an archive
path, so 'I ran their instrument' would otherwise mean a thirteenth of what it
sounds like.

1834ad1f40 port: the forced-backdrop pass decides two screens and confirms four, not six
I have said 'six forced elements' since implementing it and verified after every
change that no verdict moved -- which measured stability, not necessity. Removing
the pass entirely: the four splashes are BYTE-IDENTICAL, because palogo_eff0's
implied key 0x00000000 is lower than the lowest sprite key and the crate already
sorts it first. Only build_12/15 change, and they go black again.

Those two are the port's strongest dependency on an undecoded rule:
pgloading_eff00 there has layer: null, layer_source: none -- the only elements in
the export with neither a read nor an implied key. Their position rests entirely
on the occlusion constraint with nothing to fall back on, and that was hiding
inside a count of six.

Census: 160 layer keys read from sprites, 16 implied (every layerless primitive),
2 absent. FORMAT.md requires a consumer to tell which, and layer_source does.

Every SendMessage since 2026-08-29 returned 'delivery is not confirmed'. I

19c0aa89f1 port: index DECISIONS.md -- it already answered last iteration's question
Last iteration I filed title and title_jp's disagreement with sylpheed-cli as
mechanism-unknown, to the Decoder as well as here. Both were already explained in
this file, under headings that name the two screens.

Checked rather than assumed. title: still ties on 0x8083, 0x80a0 and 0x8010, and
the export declares paint_order_ties unresolved; the old entry's 904 px in the
glow band matches my 790 px at the same place, same 4-6/255 magnitude. title_jp:
the 'only non-integer scale' claim finds 26 keyframes export-wide, but exactly
ONE element visible at rest -- ptlogo_eff2 at 125% -- which is the pose
verify-screen uses. It survives narrowly.

The failure is navigability: 6502 lines, 111 sections, no index, so 'has this
been decided?' had no cheap answer and re-deriving it looked like diligence.

index-decisions generates the contents; check-all runs --check. No line numbers
(the first version was a fixpoint that failed its own check, and appends would
invalidate them all), and checked, because a stale index answers 'already
decided?' with a confident no.

c462496d94 port: audit BLOCKED.md against a running port; three rows were stale
The page warns it goes stale 'within the hour. It has.' Nothing audits it.

P3/P5 - the title screen was wrong in every factual claim: the boot does not end
on a plateless build 4, press_start is not unused, and the port has drawn two
builds at once for weeks. A row four lines below was already marked answered and
TAKEN for the same question -- two rows, one struck, and the LIVE one was stale.

P4 - skippable led with 'the port could not tell which bug that is'. It did:
DECISIONS records that (A) does skip in this build and every boot prints it.

P6 looping now carries the measured seam: 3.4 s of near-silence at 87.8 s.

The split is clean: every prose section added since 2026-08-29 records the
HANDOFF sha it derives from, every row in the two tables records none -- and all
three stale rows were in those tables. Not back-dated: an invented sha would make
an undated claim look checked. Both tables now say so and carry an audit date.

2d21ca5efd port: localise the title disagreement; withdraw the question I filed for it
Two iterations ago I filed title's 790-pixel gap with sylpheed-cli as needing the
Decoder's element list. That was a hypothesis dressed as a question and it is
refuted: the pixels sit at ptlogo_back2eff1 (pos 938,194) and BOTH renderers draw
it -- mean 95.60 against 95.08. A set difference would have confirmed nothing at
someone else's cost.

Also ruled out: a placement offset. Every +/-1 px roll is two orders of magnitude
worse (790 against >=175406).

The mechanism stays unknown and I am not guessing. My antialiasing test failed
its own control -- the edge mask covered 92% of the frame, so the 25.2% of
differing pixels on it is below chance.

Ask withdrawn rather than left standing: a row on a refuted premise is worse than
no row. The residual is 0.086% of one frame between two of our own renderers, on
a screen matching the oracle at 0.21%.

49b49668c3 port: add check-all; verify-screen ignored its own statistic; 'six expected DIFFERS' was wrong
Eleven tools and nothing ran them together -- the ninth instance of correct,
documented and unexercised, one level up. check-all runs the four that assert,
reports the oracle table, and gives verify-screen an allowance that EXPIRES when
the pin lands rather than standing forever. All eleven exercised first; none had
rotted.

verify-screen computed over3 because 'a single max cannot tell 2 pixels from
25 444' and then decided the verdict on max alone: main_menu (max 4, over3 0)
read DIFFERS while extras (max 3, over3 0) read OK. The bar is unchanged; a frame
with no pixel over it now gets its own ROUNDING verdict.

And corrects a claim I have given the Decoder more than once. The real count was
ten, now eight: six forced-backdrop, two rounding, and TWO UNEXPLAINED -- title
at 790 px and title_jp at 20498, neither carrying a forced element. My leaf
hypothesis is refuted: emptying draw_leaf_for changes the numbers not at all.

952c856da5 port: make the documented control sweep executable; it was prose
AUDIO-VERIFICATION.md calls its six-file sweep 'the tool's real specification'
and nothing ran it -- in a tool whose own history is two invented thresholds
caught only by controls. The same document states the principle it was breaking:
a control that does not execute is not a control.

tools/port/check-capture-controls rebuilds five of the six and asserts their
verdicts. The starved capture is gone and is reported MISSING rather than
omitted, and deliberately not synthesised from its published statistics -- a
control fitted to the answer it must give is not a control.

Two things the sweep had to learn to be honest about. check-capture emits TWO
verdicts and the doc's table compresses them; the voice control is PASS on
channels and UNJUDGED on starvation by design, so the sweep asserts the pair. And
a starved file short-circuits before the channel check, recorded as n/a rather
than FAIL -- the check did not run and the check failed are different facts.

My first 'real music bed' control was -ac 6 from a stereo source and FAILED
correctly: an upmix leaves channels silent and byte-identical, which is what the
provenance check exists to catch. The control was wrong, not the tool. Rebuilt
from six non-overlapping spans of real audio. A second attempt used aloop=-1 and
hung ffmpeg indefinitely.

77e217807a port: FORMAT.md declared the port's own export invalid; assert audio.json's stems
Audits the open format spec against the validator by breaking each documented
requirement. Four of five caught. The fifth is the doc's error: FORMAT.md said
check refuses any peak >= 0 dBFS, where the implementation is kind-dependent --
a bgm is a sum we produced and is refused at full scale, an se/voice is a disc
wave whose lossy decode overshoots and is allowed to +1.0.

The doc was wrong about our own export: confirm ships at +0.18 and the ADV voice
at +0.31. A consumer implementing a validator from FORMAT.md would have rejected
a valid tree -- the file that exists so someone can check our work without
trusting us. Corrected, with the +1.0 marked as a judgement.

Also closes the last unread authored value: audio.json's  was carried as
stems_why only, so serde ignored the value. Now deserialised and asserted in the
exporter (only sum is implemented); the assertion is proved to fire.

Files, not fixes: a failed export leaves a tree with no manifest, and every tool
then says 'is that an export tree?' -- which nearly made me conclude the
validator was checking nothing.

141cef4047 port: wire flow.json's dwell, assert the three authored values the port hardcodes
Applying the prior from six prior findings to authored/ itself: five keys had no
reader. dwell, ramp, left_right, input_during_transition, stems.

dwell is the one that mattered. Its own text says a measured hold goes there and
a number placed there did nothing -- and two iterations ago I asked the Decoder
for measurements destined for that slot. Wired now, and it stays EMPTY: the
splash dwells are declared on the disc and measured to agree.

I wired it to the wrong branch first and it did nothing, silently -- holding
longer after settle is absorbed because the screen still leaves at exit_time +
black_hold. A dwell must delay the departure. Caught only by testing the control:
+120 units moves the transition 4.46 -> 6.43 s.

ramp, left_right and input_during_transition describe hardcoded behaviour and are
written like switches. Rather than invent the missing implementations, they are
now asserted against the value the port was built for, naming the file -- which
is the distinction left_right's own why claims to make and was not making. The
validator is called, not merely defined.

c4d7553e59 port: check the five MODDING rules, and label the generated files in the asset tree
MODDING.md calls modding a constraint on the exporter TODAY and nothing verified
it -- the same shape as the black hold, skipped[], stop_bed and --focus. All five
rules pass, so check-modding is a guard rather than a fix, and it is proved able
to fail: a stripped .cmd header, a bogus.bmp, and one orphaned PNG each exit 1.

It found one thing: the .cmd encode-cache sidecars sat in the modder-facing tree
with nothing saying what they were. They now carry a header. The header is
excluded from the cache key so rewording it does not re-encode four minutes of
video, and the sidecar is refreshed whenever its text differs rather than only on
re-encode -- otherwise a header change could never reach an existing export.

Also partly answers my own question to the Decoder: there is no general
capture-path floor, because the port matches live-title-press-a at 0.00093%
full-frame and 0.000% across the band. The 0.301% is specific to that pair.

a band. Placed by sliding: y=520, a 25x drop over five pixels, and it fits at
t=236-238, the plate's own window.

Its 0.354% is not the port's error. The port reproduces the same band of
live-title-press-a EXACTLY (0.000%), and the two captures differ from each other
by 0.301% -- two thin strips, 248x5 and 206x1, the shape of a sub-pixel edge
difference. The row's job is to stay near the oracle-to-oracle gap, not reach
zero, and it says so.

I had begun writing that the attract-returned title differs from the boot title.
It is two hairlines. The connected-component breakdown stopped it.

All eight live captures are now used. The three that were idle were each blocked
by the harness, not the capture.

whatever was asked for. Now pushed into the menu model so navigation continues
from where it was forced.

With it working, each capture picks out exactly one button: ptbtn04 at 0.1355%
against 0.70-0.82% for the others on the OPTIONS capture, and ptbtn01 at 0.0705%
against 0.72-0.84% on the plain one. 5x and 10x discrimination. First time the
port's focus rendering has been checked against the game at all -- the existing
main_menu row uses an authored focus and could never have caught a focus error.

Records in flow.json that live-main-menu.png shows NEW GAME focused, so the
authored initial_focus matches the one frame it can be checked against -- and

a170e1fbc6 port: a second capture closes the sweep-geometry question; title+plate matches at 0.00093%
live-title-press-a.png was unused in the corpus. Posed at t=237 -- inside the
plate's 8-unit window -- the port matches it at 0.00093%, against 0.0124% for
the no-plate capture at leaf phase ~400. Two captures, two different phases,
both under 0.013%: a systematic sweep-geometry error would leave a floor in
both, so last iteration's caveat is closed.

Sweeping the whole screen's instant against capture 1 gives at best 0.148% at
t=230 -- 10x worse than the leaf-only fit. So that capture is the screen SETTLED
with the sweeps still looping, which is the first independent evidence for the
authored loop_leaf decision.

Fixes the cause of a flat 1% floor: --screen=X --overlay=Y pushed the raw
elapsed clock into the overlay (9 units at capture), so press_start drew nothing
-- the flag whose purpose is 'put the plate on the title'. A static overlay now
poses at its own arrival; the --boot shared clock is untouched.

Adds title_plate to verify-capture at 0.00%, the most sensitive row in it. Its
instant is FITTED and labelled as such.

Also records that I nearly committed a wrong cause for the overlay bug: I wrote
that nothing drives the overlay's clock outside a sequence. It is driven, every
frame, from view.time_units.

9610662b82 port: add --leaf-time, and the title's residual is the sweep phase (~400 units, not 357.7)
The Decoder's refined sweep fit had never been testable: verify-capture passed
it as a whole-screen --time that pose_at discarded, and asking for it honestly
poses past the title's group end. --leaf-time separates the leaf's clock from
the screen's.

Controls: the renderer is deterministic (3 runs bit-identical) and the sweeps
move 0.40% of the frame between phases, so the comparison can see them.

Sweeping the full 600-unit span gives a sharp basin at 390-415 units (0.0124%)
against 0.2532% at t=357.7 -- 20x. So the title's 0.21% residual is the sweep
phase, not structure: at the fitted phase it matches the capture as well as the
splashes do.

NOT adopted: the port loops the leaf freely and re-posing the harness to the
fitted value would be tuning until they match. Filed instead, with the question
of whether 357.7 and this are even the same quantity.

Also verified last iteration's settle-window change was surgical: only
press_start and its twin moved, 14 screens unchanged including title's
Decoder-confirmed [160,236]. Settle-window ties exist on 4 screens but all sit
under the 30-unit bar, so the arbitrary tie-break never reaches the runtime.

1. --time= was silently ignored on any screen with a settle window >= 30 units:
   pose_at overwrote the requested instant with settle_instant. ScreenView.frozen
   now marks an explicit instant and skips both clamps.

2. press_start's settle window was [0,214] -- the dead stretch BEFORE the plate
   exists -- so its settle instant was t=107, where the element is alpha 0. The
   exporter now rejects intervals in which nothing is visible. title keeps
   [160,236], the interval the Decoder's draw stream confirmed.

3. My authored looping_focus_records entry for press_start/ptbtn00 drew a dim
   focus record INSTEAD of the plate's own sprite: max 0 vs max 252.5. Deleted --
   an authored guess that overrides a decode with a worse answer is removed.

4. verify-capture passed --time=5.9617 for the title and it was never applied.
   Every title figure it has printed, including the 0.26% quoted to the Decoder,
   was measured at the settle instant under a note claiming t=357.7. Both rows now
   pose by omission and the note matches. title is 0.21% honestly; splashes
   unchanged at 0.01%.

The boot's end artifact now contains the plate (region mean 95.7 vs 33.6).
Corrects last iteration's BLOCKED row, which had the entry's effect backwards.

1. --capture with --script photographed before the first press (t=0.133 s, 10 of
   16 elements transparent). Two runs differing by two presses came out
   bit-identical and I read it as 'runtime focus never changes'. Deferred to the
   end of the script; verified max 235 and t=82 units.

2. --boot --capture= wrote NO FILE: _finish_boot() is reachable only from the
   overlay-quit branch, but line 412 quit first because _overlay_spec is cleared
   when the overlay is raised. Pre-existing, confirmed by stashing. Fixed by also
   requiring _overlay_quit_at < 0.0.

3. The artifact that now exists shows the boot's end frame is bit-identical to
   the title alone -- no plate. ptbtn00 is opaque for 8 units (236-244) and the
   boot captures at 246.54, because it waits for build 4 to finish fading at
   t=261. Both halves of that are sound and they are incompatible. NOT changed;
   filed, since what settles it is what the game does after t=244.

Defect 3 was invisible while defect 2 existed: a capture flag that writes nothing
cannot show a missing element.

Also records that runtime focus is FINE -- my contrary reading came from 410
files whose names did not match the flag I passed.

e5398be93b port: add wait:<seconds>, observe the bed's loop, and measure the seam at 3.4 s of silence
The port could not be asked to run for a stated duration -- a bare  step
is a no-op that returns at settle -- so nothing after the settle point was
observable. An 87.7 s bed on a harness whose longest menu run was 7 s.

The bed loops at 87.8 s against the track's 87.7 (r=0.947 and 0.885 on a clean
bed-only recording): loop: restart behaves exactly as authored. First
end-to-end observation of P6 looping.

The authored 'audibly wrong at the seam' is confirmed and quantified: 36
consecutive near-silent 50 ms windows, 84.40-87.80 s, about 3.4 s of silence
after a fade from RMS 2057 to 431. Recorded in authored/audio.json. It does NOT
license trimming, which would still invent a loop point.

My first wait: used create_timer and ran 39% long (30 s requested, 41.7 s wall)
because an idle scene throttles the delta it counts down on. Now polls
Time.get_ticks_msec: +4.6%. Checked before generalising: over a boot the port's
clock tracks wall clock within 4%, so animation timing is sound and the earlier
splash-dwell agreement stands.

b71c35acf4 port: the menu bed plays under the cutscene -- announced, deliberately not fixed
MenuAudio.stop_bed() exists and is called from nowhere, so the bed started on
the main menu runs through S00A and loops on past it, putting two unrelated
music tracks on the bus at once. Established from the source and authored data,
not from measurement.

NOT silenced: MISSION says leave an unmeasured detail plainly wrong rather than
plausibly invented, and music over a cutscene is caught by any listener in a
second where ducking would sound right and be a guess. _play_video announces it
instead, and stop_bed is kept as the one line to change.

Also records that the envelope correlator is unreliable for music under music --
0.15-0.42 for every candidate, peaks moving with window and template. I was
drafting '46 s of unexplained audio' when the cause was the authored
loop: restart. A margin needs a control at the SAME SNR.

e6fc2977ff port: make ScreenView say what it could not draw; refute 'first-declared paints first'
skipped[] has been tracked and read by nobody since P1, under a comment saying a
silently missing element looks like art. _note_structural prints from inside
ScreenView rather than returning a value for a caller -- routing it through a
caller is exactly what did not happen. Structural skips only; transparent-at-
rest is ordinary animation. Zero found today: a guard, not a fix.

The first version of that scan was a FALSE PASS: screen_view.gd did not parse
(a line inserted at three tabs inside a four-tab block -- the substring assert
matched a shallower indent), so grep counted zero from a dead script. The scan
now counts the summary line as a positive control.

Refutes 'the first-declared element paints first', which would have made the
forced-backdrop rule redundant since all six forced elements are index 0. False
on 8 of 16 screens -- decisively on main_menu, where index 0 is pteff00, painted
LAST, and pteff00 is a measured control.

33cc462a94 port: P7 gate verified end to end, and a defect I nearly invented from a masked correlation
NEW GAME opens S00A, plays 93.33 s against the manifest's 93.9, returns to
title. Nine film frames distinct and non-black.

Nearly filed 'the movie's audio never reaches the bus' from r=-0.0068 at the
movie's known start, with the correlator passing its own control at r=1.0000.
False: re-run bed-free on the boot path, movie audio r=0.418 and voice r=0.886
at the same start. The menu bed masked the quieter movie below detection.

The lesson is the control: I validated the instrument on clean data and ran it
on masked data. A negative needs a positive control under the SAME masking.
Third unvalidated negative in this corpus to nearly become a finding.

Also confirms the Decoder's unresolvable-element hazard does not reach
GP_TITLE: 115 .t32, 45 .rat, 18 .prm, no .tbm, every non-primitive resolvable.

06115af659 port: test backdrop coverage per instant -- scale animates, and the disc proves it
The Decoder found forced_backdrop judged coverage from declared size alone.
pbafc.prm declares 844x600 at alpha ff and draws ~17x18 px at 2%x3% scale --
a rule reading declared size would call it screen-covering.

scale_at interpolates on the same ramp as the fade, and coverage is folded into
the opaque-instant test: an instant counts only where the element is BOTH alpha
255 and covering. The previous code tested the two halves at different times.
The size prefilter deliberately no longer rejects, since an element scaled above
100 could cover from a smaller declared size.

No verdict moves: 6 forced before and after, 16 screens validate, oracle figures
identical to the digit. Nothing in GP_TITLE has a non-100 scale on any keyframe.
It is in because the data that would break it exists, not because it failed.

df3ea68366 port: P6 gate verified with sound on the bus; tighten the backdrop guard to a positive primitive test
verify-menu-audio records the Master bus over the P5 walk under the Dummy
driver. A dead press is bit-identical to the bed alone; all three cues match
their exported wave in the recording with margin over a bed-only control; the
cue order matches the script order, which the correlator was never told.

The first version of this tool counted envelope bursts above a multiple of the
bed and gave 4 cues on one run and 0 on the next from the same script. Replaced
with template matching, which has no tuned constant. Cue LENGTH is deliberately
not asserted -- the bed masks the tail and I nearly filed that as a defect.

Also acts on the Decoder's .tbm self-refutation. No port verdict is affected --
all six forced elements are .prm solid black, and GP_TITLE has no full-screen
.tbm at all -- but the guard was sprite.is_none(), a symptom test of the same
shape as the one they say fixed their symptom not their cause. Now role ==
primitive. Six verdicts identical, 16 screens validate.

733e376366 port: audit what rests on a single draw-stream run; black_hold_units=9 sits at the top of its range
Their ARM=early disclosure (~40% silent trigger loss) makes every draw-stream
figure n=1. Exactly one port constant depends on one: the black hold. Three of
its supports have moved -- the 105-frame count they revised to 114, the 2.231
corroboration they retracted, and a run-average rate now known to drift 33%.

Redone on their corrected segments the two runs give 8.95 and 6.71 units, not
one number: overlapping +/-1 error bars are not agreeing central values when one
frame is a third of the quantity. Range ~6.5-9.2, port at the top.

Value UNCHANGED and proposed rather than adopted -- it would be my arithmetic on
their instrument. Filed with the single run that would settle it.

Also checks their statistics: per-boot excesses reproduce exactly, and their
2.3 sigma uses population SD where sample SD gives 1.89 -- cutting against their
own concession. Neither framing reaches significance.

cb111e0642 port: their corrected calibration matches the file at all six points; guard the 60 against emulator drift
Counting indices/4 lands every transition where the export's declared alpha>0
count changes, within a half-open boundary. Their quad counts (1/2 publisher,
3/6 developer) also reproduce exactly when restricted to sprite-bearing
elements -- independently confirming the layerless backdrop is absent from the
batch they log.

Refutation: their drift explains the corpus 4.1% in SIGN but overshoots in
magnitude 2.4x (predicts a 1.369 ratio, corpus shows 1.278, declared 1.214).
The drift was measured in their container and the 4.1% belongs to a different
instrument -- the same transfer I just got wrong with build 4.

Guards keyframe_units_per_second at the constant itself: 60 is the game's
logical rate, not a frame rate, and the 33% drift is not evidence about it.

77292e98fc port: withdraw 'the boot is known too fast' -- the splash dwells are declared and the port already played them
The Decoder measured both splashes over 3 cold boots: publisher t=0..255,
developer t=0..210, the developer agreeing with wall clock to 1.1%. The port
emits each declared value plus the 9-unit black hold, exactly. No code change.

My error was the generalisation, not the arithmetic: build 4 is the title, whose
exit is caused from outside its timeline, so it holds; a splash's exit is caused
by nothing, so it plays out. I used the one boot screen the port is unaffected
by to overturn the two it governs. Declining to scale by 9x while adopting the
conclusion that implied was half a caution.

Also refutes their two splash boundaries as not comparably anchored: 2.237 vs
2.414 units/frame in one boot, and the publisher has a glow symmetric with the
developer's three.

2e29572b02 port: the clock freezes at settle -- my window is the game's, and the boot is known too fast
The Decoder measured build 4's top-level clock stopping inside [160,236]. The
exporter computes title's settle window as [160,236,198] from the file alone.
Same interval, two independent methods -- the first evidence for the settle
instant that does not come from our own renderer. ptcopyright reaching alpha
255 exactly at t=160 agrees from a third direction.

Corrects a claim in three places: timing.json, flow.json and boot.gd all said a
screen's dwell IS its keyframe group and the port reproduced 'the disc's own
pacing'. Build 4 declares ~120 presented frames and dwelled ~1100. The decision
to hold zero extra stands; the claim that it was faithful does not.

Checks their two declared spans against the file: both exact, with a 106-vs-105
interval-convention quibble that changes nothing.

91c76efbbf port: close the span row -- 256 and 211 are both ours, on different splashes
The Decoder resolved it: palogo_eff0.prm is on BOTH splash pairs, publisher
running to t=255 (256 instants) and developer to t=210 (211). My own census
table had both numbers side by side and said the offset was not constant; I
filed a disagreement anyway by comparing one of my numbers to one of theirs.

Span convention confirmed as implemented. Records their counterfactual: the
hold decides 55% of verdicts disc-wide, and palogo_eff0's measured order rules
out the reading I nearly shipped.

Boot gate re-run after the reorder and still holds.

ad634bd79c port: census every layerless full-screen element; the forced-backdrop quantifier misses nothing in GP_TITLE
Tries to refute the rule by SUFFICIENCY rather than correctness: a strict
'all others visible' quantifier fails quietly, so the question is whether any
full-screen opaque backdrop misses the bar and keeps hiding its screen.

None does. Everything that fires is at 100% of others; everything that does not
is at 13-47%, and pteff02 never reaches alpha 255 at all. No borderline case.

Reproduces the Decoder's second control exactly (pteff00 forced below 3 of 23)
and shows their palogo_eff0 span gap is not a constant offset -- 211 is the
number our developer_logos row does reproduce.

Also retires the 'loading screen fade quad rests OPAQUE BLACK' row: resolved by
the rule, and it recorded rest.t as 38 where it is 0.

build_12 and build_15 rendered mean 0 at every instant of a PLAYING timeline,
and verify-screen scored both OK -- two renderers sharing implied_layer_key,
comparing nothing against nothing.

Implements the constraint as a post-pass over ui_layout::derived_paint_order,
with both of the Decoder's limits copied verbatim: layerless elements only (a
sprite's element alpha says nothing about its texture's coverage) and NOT a
name heuristic (palogo_eff0 is named like an overlay and paints first).

Both controls reproduce: palogo_eff0 forced first, pteff00 still last on all
four title screens at exactly 2 opaque instants. Splashes unmoved against the
oracle at 0.01%.

2b646f5b1e port: the loading screens are black at EVERY instant, which disproves my layer rule
build_12 and build_15 have rendered blank since P3 and I had filed it as a rest()
casualty. It is not, and the corrected keyframe association makes it provable.

pgloading_eff00, a 1280x720 black quad, is opaque alpha 255 from t=0 to t=38 and
clears at t=48. Every other element on the screen peaks between t=8 and t=32 and
is gone by t=32-40. So the quad covers the entire span in which any content is
up, and clears only after everything else has faded. Rendered with the timeline
PLAYING at t = 20, 30, 36, 40, 42, 44, 46 and 50 units, the frame is mean 0 at
every one.

That is not a bad choice of pose. Under the port's current layer rule there is no
instant at which this screen shows anything, and a loading screen that is black
for its whole life is not what the game does -- a proof by contradiction rather
than a preference.

THE RULE UNDER SUSPICION IS MINE AND IT IS NARROW. pgloading_eff00 carries
layer_source "none" and the exporter sorts a layerless element LAST, on top.
Every other full-frame primitive in the export has a layer key (main_menu, extras
and title all give pteff00 0x00008030), so this only ever bites here -- which is
why it survived eight milestones behind two screens nobody draws.

Where a layerless element sorts is a DECODE and I have not answered it. If the
game sorts it first, behind everything, the screen renders and the quad becomes a
backdrop, which is consistent with the contradiction but not established. Asked
rather than flipped.

It does settle that verify-screen's BLANK verdict on those rows was right:
sylpheed-cli agrees with the port there precisely because it shares the
assumption under suspicion.

Also recorded: the Decoder has withdrawn "the game never draws eff3" -- it draws
all five -- and the mechanism is the one my developer-splash refutation caught a
layer down. A draw batches several quads and the log dumps only the first 8
vertices, so min/max merges them; eff3 lies entirely inside eff4 so the union is
exactly eff4's extent. My 525x259 was gamearts_eff merged with seta_eff the same
way. Nothing in the port changes: eff3 was never dropped and the splash still
draws three sprites.

e4775f64cc port: the menus' residual is the tone floor, and extras is not really 3x worse
extras sits at 0.19% differing against main_menu's 0.06%, on two screens of the
same family. The signed difference explains it: both are uniformly +9 to +12
brighter in the dark outer columns, in nearly identical patterns (+12.13/+12.29
against +11.63/+11.03 at x=0; +10.60/+9.05 against +10.24/+8.84 at x=960). That
is the transfer curve -- gamma > 1 in the darks -- with no dipole, no
displacement and no missing element.

So the 0.06/0.19 gap is not a difference in fidelity. The thresholded count only
sees pixels differing by more than 64 levels, which are text and sprite EDGES,
and the two screens have different amounts of high-contrast edge. The level
disagreement, which is what a tone term produces, is the same on both. I had
taken the ratio of two counts as meaningful -- the bounding-box lesson in a
different costume.

A DIAGNOSTIC TRAP OF MY OWN: the first pass reported 10 of 18 elements
"transparent at rest" on extras -- the buttons, the title, the frames -- and
looked exactly like a missing-element bug. `--screen=NAME` without `--time`
renders at t=0, and pose_at clamps t to minf(t, settle_units), so t=0 stays t=0.
With --time=2.0 it draws 18 of 18. The tool was right and my invocation was
wrong, and it reported a WORSE problem than existed, which wastes an iteration
rather than hiding one.

REFUTATION ATTEMPT, SURVIVED: the Decoder's 239.8 units for palogo_sqex's alpha
>= 1 span, which is the denominator of the units-per-frame conversion behind the
9-unit black hold I just authored. Computed independently from my export under
the linear ramp the port already uses: alpha first reaches 1 at t=15.0588 and
last exceeds it at t=254.8750, giving 239.816 units. Agrees to four significant
figures, from different sides of the same record -- which is what makes that
constant safe to hold.

3e578882c2 port: the title's sweeps loop, the black hold is 9 units, and one claim refuted
THREE THINGS FROM THE DECODER, one of which I am not taking.

REFUTED: "the developer splash is one composited quad, the bounding box of the
three logos". The observed quad is 525x259 at (378,155). The three logos'
bounding box is 500x421 at (390,164) -- a 259-tall quad CANNOT contain them, and
palogo_anima alone starts at y=449, thirty-five pixels below that quad's bottom
edge. The observed quad matches the union of gamearts_eff and seta_eff, 521x261
at (379,154), to about four pixels in every dimension -- and both of those are
TRANSIENTS my own census flagged, dark by t=45, so a frame containing that quad
is a build-in frame rather than the settled screen. I cannot see their draw
stream, so I sent the arithmetic rather than a verdict, and the port keeps
drawing three: I will not stop drawing an element on a claim whose stated
identification excludes that element from its own bounding box.

THE BLACK HOLD IS 9 UNITS, NOT 12. I authored 12 from Q7's luminance plateau of
0.17-0.23 s, supported by the menus' transition quad. The Decoder counted
SUBMITTED QUADS instead -- luminance cannot separate the outgoing fade's tail
from true black. Four frames with no sprite quad at all, at 2.284 units/frame
derived from the disc as its own clock, gives 9.1 units = 0.152 s (6.9-11.4).
That overlaps the luminance figure only at the top, and the true black is SHORTER
still since both boundary frames carry picture. My 12 was supported by analogy --
a different screen's quad on a different path -- and a number that fits by
analogy loses to one measured in place. verify-dwell's bound moved with it; both
screens still agree.

THE TITLE'S SWEEPS LOOP. The oracle shows the quad oscillating over its whole x
range and resetting hard, one reset in the first title dwell and two in the
second. The loop-length field could NOT have settled it, correcting a hope I had
stated: both records declare exactly their last keyframe time, slack zero, and
"loops at 600" and "runs once for 600 and stops" write the identical header.
Verified on the two sweeps' LCM, since their periods differ: 600 and 720 realign
at 3600 units, mean diff 0, against 0.438 at half that.

Scoped to the title. The menus declare the same lengths but the oracle
measurement is of the title, and my own weak evidence points the other way there
-- best match with the sweeps off-screen, three times worse mid-screen, against a
73% on-screen duty cycle if they looped. Two weak signals in opposite directions
is a reason to scope, not to pick.

9540909a6f port: refute my own "the menu residual is the sweeps", and show the narrow windows are harmless
TWO RESULTS, both correcting things I had written.

THE NARROW SETTLE WINDOWS ARE NOT A GAP. Adopting the settle instant left
main_menu and extras on per-element rest() -- windows of 12 units, below the
30-unit bar -- and I recorded that as something left behind. rest() is malformed
only for a TRANSIENT, and the transients are precisely on the screens whose
windows are wide: title (76) has ten, publisher_logo (190) and developer_logos
(145) have one and three, and main_menu and extras have NONE. The discriminator
is returning to dark far before the screen's own end -- ptlogo_back2eff1 is dark
again at t=58 while the title runs to t=269 -- as against the ordinary
fade-in-hold-fade-out every menu element has, where rest at 255 IS the settled
pose. Not claimed as a rule: two screens having narrow windows and no transients
could be coincidence, and n=2 is where I have gone wrong before.

REFUTED, MINE: "the menu residual is localised on the ptloop sweeps", which I
have written twice. It came from reading the BOUNDING BOX, which sat at (441,230)
-- the sweep position. Sweeping the leaf's phase against the live-menu capture:
0.063% at t=60, 0.183% mid-screen at t=350, 0.061% parked at t>=600. With them
parked the box is 834x358 at (445,167) -- the button column, where the focus
signature lives. On extras the same test moves the box (398x295 at the sweep
position, then 736x525 spread) while the magnitude barely changes, 0.192% against
0.200%.

So the box moves with the sweeps and the residual does not. A bounding box over
scattered pixels tells you where the outermost differing pixels are, not where
the difference is -- and I had been quoting it as if it localised a cause.
verify-capture prints that box, so this is a caution about reading my own tool.

And a first piece of evidence on whether the sweeps loop: the disc gives one pass
ending parked off-screen, ORACLE-CAPTURES says they "move continuously" which I
had read as implying a loop, and the idle menu capture matches best with them
OFF-SCREEN. One capture and a weak instrument for an absence, but it is the first
evidence either way and it points against looping.

7230fa846e port: the publisher residual was a missing black hold -- we had both dismissed it
I carried this as "0.03 s outside a composite bound, probably a property of the
bound rather than the game", and the Decoder agreed. Both wrong, and the way it
was settled is the point: I stopped reasoning about the bound and filmed the
transition.

At 0.05 s the port fell straight out of the publisher's fade into the developer
logos -- mean 5.06 -> 0.32 at t=4.20, then 5.65 at t=4.25. NO BLACK FRAME AT ALL,
where the oracle measures a 0.17-0.23 s pure-black plateau (HANDOFF Q7). The
bound was fine; the port was missing a fifth of a second of black, and had been
since P3.

Authored at 12 units because the boot path has nothing to read it from:
publisher_logo and developer_logos each carry a single palogo_eff0, a 1280x720
primitive with ONE keyframe at t=0 -- static, not a transition ramp. The menus'
quad declares black for 12 units and 12/60 = 0.200 s sits mid-range, so the
number is the disc's where a screen has one.

Filmed after: t=4.25, 4.30, 4.35, 4.40 all at mean 0, then the developer logos at
4.45. publisher interval 4.26 DIFFERS -> 4.47 agrees; developer 3.62 -> 3.73,
still agrees. Settled-frame comparisons untouched, as they should be.

THE LESSON IS THE SHAPE OF THE DISMISSAL, NOT THE NUMBER. "A 0.03 s miss against
a bound composed from two measured ranges plus jitter slack is more likely a
property of the bound" is plausible, was accepted by both of us, and was wrong.
The composite bound is why the miss looked small -- the underlying gap was 0.2 s
-- and a plausible explanation for a small number is how a real defect stays
hidden. The film cost one command.

Also recorded: the Decoder has reproduced across two build-ins that the console
NEVER draws ptlogo_back2eff3 (0 draws against ~5 expected), with sampling phase,
invisible draws and position error all ruled out -- but WHY is not established,
and nothing in eff3's record differs from its neighbours. The port keeps drawing
it, deliberately: dropping an element the disc declares on a measurement with no
mechanism is authoring a behaviour neither agent can derive, and nothing this
port gates on would notice, since the flashes live only in the build-in and
verify-capture compares the settled frame.

dee6c495ad port: their "do not draw all five flashes" flag, checked -- the port already staggers them
The Decoder caught the title's build-in on the console and found ptlogo_back2eff3
never drawn -- not a miss, but phase: a flash's peak is 2 keyframe units, 0.85 of
a presented frame at that pacing, so the console shows a SUBSET on any given
play. The warning was that drawing all five would read heavier than the real
thing.

Checked rather than reasoned about. Sweeping the build-in with --no-hold, the
port draws them sequentially -- eff1 at t54-56, eff2 at 58-60, eff3 at 60-62,
eff4 at 62-64, eff5 at 64-68 -- never more than two at once, and those only where
their declared windows abut. That is the stagger the disc declares. The pile-up
was the rest() bug and it is fixed.

SO THE DIFFERENCE FROM THE CONSOLE IS PRESENTATION RATE, NOT CONTENT. At 60 fps
each 2-unit flash gets ~2 frames; at the console's pacing it gets 0.85, so some
are skipped. A frame-by-frame comparison of the build-in against a console
capture will show flashes the console missed -- a fact to know rather than a bug
to fix. The settled comparison verify-capture makes is unaffected: at t=198 none
of the five is drawn.

Also recorded: my top-level restriction on the settle window was verified by them
rather than merely accepted ([160,236] width 76 against [269,540] width 271 with
the leaves in, which is an instant after every top-level element has exited); the
120-unit loop is confirmed from the guest's own vertex colour alpha, observed
range 0..80 against a decoded peak of 80, with the decoded ramp fitting at RMS
13.16 against 38.18 reversed; and a trap for any future draw-stream tooling here
-- a 2D draw's identity is its vertex geometry, not its bound texture, because
these sprites sample large shared pages.

fb472e8dfc port: pose a settled screen at ONE instant -- title 1.81% -> 0.26%, splashes to 0.01%
The Decoder's finding, applied. `rest()` returns each element's last hold
keyframe chosen independently of every other element: right for anything that
ends the screen settled, exactly wrong for a transient. The title's
ptlogo_back2eff1 is a two-frame flash (0 until t52, 255 at t54-56, 0 by t58), so
its last hold IS the flash peak and rest() left it burning -- five of them, drawn
at once.

The settled instant is the longest interval containing no keyframe time, over a
bundle's TOP-LEVEL elements. Reproduced here before adopting: title [160, 236],
midpoint 198, the Decoder's number to the unit. The top-level restriction is what
makes it match -- including the ptloop leaves gives [269, 540].

AGAINST THE ORACLE:

  title            20.92 RMSE  1.81%  ->  14.61 RMSE  0.26%
  publisher_logo    9.05       0.75%  ->   2.17       0.01%
  developer_logos   8.86       0.33%  ->   3.05       0.01%
  main_menu                    0.08%  ->              0.08%   window too narrow
  extras                       0.19%  ->              0.19%   window too narrow

Seven times fewer differing pixels on the title, seventy-five times fewer on the
publisher splash, whose differing region is now a 13x18 box. The largest
correctness gain this port has had, and none of it is mine -- it is a decode
computed from the keyframe table with no reference to any capture.

APPLIED ONLY WHERE THE WINDOW IS WIDE, and the bar is not invented. This export's
widths split with nothing in between: 214, 190, 145, 76, then 12, 12, 8, 4. The
bar is 30 units -- the Decoder's disc-wide census puts the knee there (30% of
bundles >= 30, 42% under 10, the latter mostly loop* fragments meant to be in
motion) and this export's screens sit 4x either side with nothing between 12 and
46. Two independent populations agreeing on where to cut.

Checked unbroken: boot pacing unmoved, scripted walk runs end to end with focus
restored.

Also recorded: my "34 focus-record elements, only 2 varying" is right for
GP_TITLE and reads as a fact about the format -- disc-wide it is 210 varying, 202
with rest() at the peak, concentrated in the paks a wider port reaches next. And
their sharper framing, which I have adopted: a pulsing element has no resting
pose at all, so rest() is MALFORMED rather than mis-answered on one.

5be9aea41b port: BLOCKED -- the paint-order tie-break costs zero pixels on every screen we ship
The old figure was 24 overlapping tied pairs, and it was a rest() count: 10 of
the title's 11 tied pairs are between the five transient flashes, which are
transparent on a settled screen. Measured at settle, the cost is ZERO on all five
screens this port ships, and the only non-zero anywhere in GP_TITLE is 1 px at
delta 1 on the Japanese title, which is out of scope. Sweeping every keyframe
time and midpoint, the live-pair count is flat across the settle window, so it is
not a knife-edge.

Recorded with the Decoder's own caveat rather than smoothed: four loading bundles
report zero with no live control, so those are a weaker zero than the other six.
And why ties order as they do is still unknown -- it now costs one pixel.

f3f31d4923 port: the plate's period is 120, decoded -- and 105 was falsified with my own ring number
The Decoder found it in the format: a nested record is itself a RATC bundle and
its header's +0x08 is the LOOP LENGTH. A record's keyframes need not fill it and
the slack is a hold at the final pose, so ptbtn00f is 105 units of ramp inside a
120-unit cycle -- the glow rests dark for 15 units. The five ptbtn0Nf records
fill their 120 exactly, which shows the slack belongs to that record and not to
the format. Disc-wide over 1781 timed nested records: 92.3% declare exactly their
last keyframe time, 7.7% more, 0 LESS -- the falsifier never fires.

THE DECISIVE TEST USED THIS PORT'S NUMBER. Both candidates need the same emulator
pacing factor, and the ring measures it independently: declared 120 -> 2.177 s ->
1.0885. 105 units needs 1.211-1.337 to reach the measured 2.12-2.34 s, which
EXCLUDES it; 120 units needs 1.060-1.170, which CONTAINS it. Two different
elements in different bundles, separate runs, tied only by both declaring 120.

My three readings in order are the useful record: 129 (105 + the since-deleted
exit_ramp_units) fitted the measurement for a reason that evaporated; 105 (the
group length) I shipped knowing it was 17% short; 120 is decoded. And the
123-vs-129 pair I once called unseparable STRADDLED the right answer without
containing it -- the sharpest argument I have seen against treating "two
candidates, nothing separates them" as if the truth must be one of the two.

Verified bit-identical 120 units apart (mean 0), 0.061 at a quarter, 0.888 at
half. Still authored because the pinned tag does not expose +0x08; delete the
entry the day a tag does.

THEIR rest() FLAG, CHECKED RATHER THAN ASSUMED: they warned a focus record is the
kind of element rest() mishandles. Censused -- 34 focus-record elements, only 2
with a varying alpha, both ptbtn00f, whose rest.alpha of 80 IS their peak,
exactly the pathology described. The port does not hit it because the plate draws
through the loop path, and the other 32 are constant-alpha so rest() is safe.

521b0b1f85 port: the focus ring had silently stopped, and the plate's period is now the disc's
BLOCKED said the record-layout change touches five things: pose_at,
settle_units, spin_period_units, exit_ramp_units and the plate. I checked two,
reported that, and did not work the rest of the list.

`spin_period_units` required "the first timed and the second untimed". Under the
corrected layout the ring reads t=0 rot=0 and t=120 rot=360 -- both timed -- so
the rule returned 0 and THE FOCUS RING STOPPED SPINNING. Nothing reported it: a
period of 0 is a legal "this element does not spin".

Rewritten to take the SPAN between the two poses: 120 - 0 = 120 units, the same
number the old rule produced, which is evidence the corrected layout is
self-consistent rather than merely different. Verified the way P5 verified it,
by bit-identity one period apart on the ring's own 60x60 box so the ptloop sweeps
cannot confound it: 0 at +120 units (twice), 8.61 at a quarter period, 8.88 at
half.

Three wrong instruments on the way, and the sequence is the lesson. A whole-frame
`max` saturates on one rotating edge (adjacent frames scored 131 with a mean of
0.022). A live --menu filmstrip jitters by up to a frame, which is ~3 degrees of
ring. And a whole-frame comparison is dominated by the sweeps, which move 480 px
over one ring period. `--focus=<id>` was added so a --screen run can draw a focus
record deterministically, which is what made the check reproducible.

THE PLATE'S PERIOD IS NOW 105, THE DISC'S OWN GROUP LENGTH, and it disagrees with
the measurement. The ambiguity the entry carried is gone -- it used to say the
cycle might restart at t=6 rather than 0 and that nothing separated them; the
group now runs t=0 to t=105, both at alpha 0, and there is one reading. But 105
units is 1.750 s, or 1.906 s scaled by the factor the ring shows between its
declared 120 and its measured 2.177 s -- about 17% below all four corpus timings
(2.12 / 2.19 / 2.34 / 2.31). The old 129 gave 2.34 s, at the top of the range,
which is why it looked right.

129 was the last timed keyframe plus exit_ramp_units, and that constant is
deleted. A period built on a constant that no longer exists cannot stay even
though it fitted better, so the port ships the disc's number and says it is
wrong. Verified bit-identical 105 units apart, 0.83 at 30 units.

ace071dd7b port: delete exit_ramp_units, invert the format's own rule, and guard a scale-0 leaf
FOUR THINGS, and the first is what MISSION section 3 calls the measure of
progress.

DELETED `exit_ramp_units` AND `exit_ramp_seconds`. They were authored because the
disc had no time slot on a group's final keyframe, so the ramp into it was the
one unknown duration per screen. Under the corrected record layout that keyframe
does not exist -- a group is an 8-byte header then frames x {u32 time; 36-byte
pose} and every pose is timed. VERIFIED DEAD BEFORE DELETING: setting it to 9999
(166 s) moved the boot's transitions by 0.04 s, which is wall-clock jitter, and
both uses in ScreenView are gated on a condition that no longer fires on any of
the export's 866 keyframes.

INVERTED THE FORMAT'S OWN RULE. `check.rs` enforced "the final keyframe has no
`t`; the disc has no time slot there" and FORMAT.md stated it. Both are now
backwards, and the validator fired 150 times on a re-export. I had not run
`check` between pinning the tag and measuring against the oracle -- the pixel
harness was green while the format validator was failing on every screen with a
multi-keyframe group. A correctness harness does not replace a format one; they
fail at different layers.

GUARDED A SCALE-0 LEAF, which the Decoder hit in its own renderer: its leaf
branch marked the element drawn unconditionally while the blit returned early on
zero scale, so a scale-0 leaf suppressed its parent and blanked the element --
live on all four loading screens. This port did not have the bug only because
authored/rendering.json happens not to list pgloading_loop5. That is an accident
of a gate written for another reason, not a defence, so `_draw_leaf` now reports
whether it drew and `_draw` falls back to the parent.

ISOLATED THE PACING QUESTION rather than leaving it as a suspected regression.
Legacy association: publisher 4.70 agrees, developer 3.92 DIFFERS. Corrected:
publisher 4.26 DIFFERS, developer 3.62 agrees. Both misses are ~0.03 s outside a
composite bound. The association traded which screen is marginally out; it did
not regress the pacing.

Bumped the pin c -> d for the parser and audio changes. Its headline renderer
change does not reach this port: sylpheed-cli builds from the workspace crate.

16ab24480d port: the 11.5 px was the fit's resolution -- and the lesson inverts
The Decoder closed it by ADDING OBSERVABLES, not by tuning. The vertex buffer
carries positions and colours at the same instant, so all four quantities must
agree on one t: quad A x solves to 357.88 and quad B x to 357.58, both +/-0.12
units, against 355.75 +/-1.54 and 354.09 +/-1.89 from the alphas. Alpha moves
only 0.27-0.33 levels per unit, so one byte of quantisation is worth 1.5-1.9
units -- 6-8 px of sweep at 4 px/unit. That is the whole of the 11.5 px. At
t=357.7 the centres land within 0.70 px and both alphas inside one level.

THE LESSON IS THE EARLIER ONE INVERTED AND IT IS THE HALF WORTH KEEPING.
Checking a wrong rule against alpha made it look confirmed; here the same
insensitivity MANUFACTURED a residual that did not exist. An insensitive quantity
does not merely fail to falsify -- it invents error. Solve on the fastest-moving
field, check the slow one, never the reverse. I was already looking for a pivot
rule to explain 11.5 px when they wrote; there was nothing to find.

REFUTATION ATTEMPT, survived with a nuance: they state the leaf pivot is (200,90)
on a 399x180 sprite, "the pivot is the centre, so rotation displaces it by
nothing". Checked against my export -- pivot [200,90], sprite 399x180, true
centre 199.5,90. It survives, but the sprite is ODD-WIDTH so the pivot is the
centre to within half a pixel rather than exactly. No consequence against their
0.70 px agreement; worth stating because "displaces it by nothing" is the kind of
sentence that later gets leaned on for a sub-pixel claim.

verify-capture now poses the title at t=357.7 rather than 355: RMSE 21.07 ->
20.92, differing 1.82% -> 1.81%. Marginal, and it is the right pose for a stated
reason rather than a better number.

AND ptlogo_eff2 IS WITHHELD FOR A BETTER REASON THAN MINE. I had it on caution
about untested generalisation; the Decoder points out it is on title_jp and
MISSION section 7 scopes out "localisation beyond English", so it is not a
question this port has to answer and the parked Japanese capture does not need
reviving for it. authored/rendering.json now gives scope first and undecidability
second. Widening scope to close a residual would have been the wrong trade.

e5be03709a port: pin formats-pin-2026-08-29c -- the knob I tested last iteration was retired
I tested the wrong switch. SYLPHEED_KF_TIME_SHIFT is a superseded partial fix: it
got the association right but LEFT POSE 0 UNTIMED, which is exactly why the
untimed keyframe appeared to move from last to first. The real correction is the
DEFAULT in the tagged crate, with the old reading behind SYLPHEED_KF_TIME_LEGACY.
So last iteration's five rows measured a mismatch against a knob nobody should
use -- I suspected they were not decisive, I did not suspect the knob was retired.

THE CONSEQUENCE IS MUCH SMALLER THAN I BUDGETED. A placement group is an 8-byte
header then frames x {u32 time; 36-byte pose}, so pose 0's time is the group's
lead-in word and every pose is timed. Measured on the re-export: 866 keyframes,
0 untimed. `pose_at`'s "the final keyframe carries no t, so give it a synthetic
time" premise does not invert, it DISAPPEARS -- dead code rather than wrong code,
which is why nothing needed re-deriving. And the leaf now reads t=0 x=-639,
t=150 x=-39, t=540 x=1521, giving x=781 at t=355: the Decoder's predicted
top-left, and the 1300 px discrepancy is gone.

Pinned by tag, which is what MISSION section 2's tagging rule is for. BLOCKED was
wrong in both directions -- "cannot be taken yet" AND "only when that branch lands
on main". It arrives when the tag is pinned.

COST STATED: sylpheed-cli builds from the workspace crate, so until this reaches
main the exporter and the reference renderer read different decoders and
verify-screen compares two eras. verify-capture is unaffected -- it compares
against oracle captures and never touches the CLI. Revert to the path dependency
when the tag is an ancestor of main.

Oracle: publisher_logo 1.00% -> 0.75%, developer_logos 0.39% -> 0.33%, and
extras' differing region COLLAPSING from 736x525 to 398x295 at the sweep position
-- the residual localised onto the one element still in question. title unchanged
at 1.82%, now posed at t=355, the Decoder's FITTED sweep time. t=390 measures
1.65% and picking it would be fitting the pose to the score.

REFUTED, MINE: "ptlogo_eff2 is the single drawn element at a scale that is not a
whole multiple of 100%". That census was parents-only; the 45 leaves hold
thirteen distinct non-whole-multiple scales and 125% is among the rarest at two.
The claim's real content was "the only one the port draws" -- about my element
set, not the disc.

1380bbdcff port: re-run the P5/P6 gate, and verify the cues with a null control rather than a detector
The leaf path, the plate pulse, the BGM level fix, the voice export, the focus
fix and a diagnostic flag have all landed since the gate was last run. I had been
verifying pieces against captures without once re-running the whole walk, which
is the mission's actual test.

It works. Nine steps unattended: down x4 through all five buttons, (A) into
EXTRAS, (B) back to main_menu with FOCUS RESTORED to ptbtn05 (HANDOFF Q5's rule,
live), up, (A) on OPTIONS which prints the archive gap rather than pretending.
Every shot non-blank. Filmstrip shared as 1788027380-788b1faafc3e.

THE SOUND IS VERIFIED BY A NULL CONTROL, NOT A DETECTOR. I first tried counting
sharp level rises: it found ONE onset in the walk and THE SAME ONE in the music
bed alone, which contains no cues -- a 50 ms envelope cannot see a short cue over
the bed. The right response to a detector that cannot separate its control from
its subject is to stop using it, not to widen the window until the numbers look
better.

So the technique that settled the voice: shadow the three cues with silence
through data/mods/, run the identical walk, compare.

  cues playing    peak +0.0003 dBFS   RMS -18.36
  cues silenced   peak  -4.74  dBFS   RMS -20.78

Silencing three sound effects costs 4.74 dB of peak and 2.43 dB of RMS, and the
walk's peak is SET BY a cue rather than by the music. The mod log confirms
exactly three files shadowed. No detector, no threshold, and the control is the
same run with one input changed.

Recorded under the Dummy driver. It shows the cues reach the Master bus at the
right moments; it does not show they are the cues the game plays -- that is Q8,
and authored/audio.json still carries the offsets as measured.

01fc4cd133 port: the -324 was the old keyframe association, and the corrected one was available all along
The Decoder found it and it is not geometry: my leaf path pairs each pose with
the NEXT pose's time. Fed my pairing into its own interpolation it reproduces
-324 to the digit; corrected, t=355 gives centre 980.5 against 992.0 measured. So
there was no 1300 px pivot mystery, and saying both numbers rather than hunting
one is what surfaced it.

CORRECTING BLOCKED: this was never gated on a branch landing. The row said the
change "cannot be taken yet ... reaches the port only when that branch lands on
main". Wrong -- ui_layout.rs in this checkout carries the corrected association
behind SYLPHEED_KF_TIME_SHIFT=1 and has all along. I read that file twice this
session, once for rotation_deg and once for the leaf note, without noticing the
switch.

Ran the experiment. Re-exported under the shift and asked the oracle:

  publisher_logo   1.00% -> 0.75%   better
  developer_logos  0.39% -> 0.33%   better
  title      RMSE 21.07 -> 20.41    better (area 1.82 -> 1.86, worse)
  main_menu        0.06% -> 0.10%   worse
  extras           0.20% -> 0.24%   worse

NOT DECISIVE, and the reason is the point: under the shift the untimed keyframe
moves from LAST to FIRST, while `pose_at` is written around "the final keyframe
carries no t, so it is given a synthetic time exit_ramp_units after the last
timed frame". The numbers measure a renderer/association mismatch, not the
association. Adopting it means re-deriving exit_ramp_units, settle_units,
spin_period_units and the plate against a layout where the untimed frame is
first. Export reverted to the default; doing that work hastily is how a 1.8% gap
becomes five wrong ones.

THE METHODOLOGICAL POINT IS THE DECODER'S AND IS THE BEST THING HERE: its rule
matched because alpha at t=355 sits inside a long segment where a one-keyframe
shift barely moves it, while x sweeps 1560 px over the same span. It confirmed on
the insensitive quantity, I was wrong on the sensitive one, and neither of us saw
it until they were compared. CHECK A NEW INTERPRETATION AGAINST THE FASTEST-MOVING
FIELD YOU HAVE, NOT THE ONE THAT HAPPENS TO AGREE. That is a control chosen where
it could not fail, which is a different failure from the uncontrolled instruments
this session has collected.

An 11.5 px residual is left and is not to be fitted.

cb616ab9af port: implement the decoded leaf composition -- and it does not close the 1.82%
The Decoder decoded the rule I refused to guess: draw the leaf on its own
timeline, do NOT multiply the parent's alpha in. Multiplying is refuted rather
than unsupported -- at the fitted time the parent has expired, so leaf x parent
predicts zero for both quads and the sweeps would be invisible. They are drawn.

Implemented: `_draw_leaf` runs the leaf unclamped, like the spinning ring and for
the same reason -- held at its own rest.t the leaf sits at x=1521, entirely off
the right edge, so `holding` would delete the sweeps rather than settle them.

AND IT CHANGES NOTHING MEASURABLE. The title is still 1.82% against the oracle:
1.82 at t=261, 1.81 at t=355, 1.79 at t=420. At t=355 my interpolation puts the
leaf's top-left at x ~ -324, off-screen left, where the Decoder's model puts the
quad's CENTRE at 981. Those cannot both be right, and it is not something to tune
away -- it is a disagreement about how the leaf's keyframes become a placed quad,
most likely in the pivot and the rotation about it. Handed back with both
numbers.

So: the exporter no longer drops the data, the composition rule is implemented as
decoded, and the port's largest oracle gap is exactly where it was. Fixing the
export was necessary and not sufficient.

TWO FLAGGED ELEMENTS DELIBERATELY NOT DRAWN, in authored/rendering.json with
reasons. title_jp/ptlogo_eff2 (parent 125%, leaf 100%) is the same shape and is
the element DECISIONS has recorded since P1 as the largest render disagreement --
but the Decoder said plainly "I have not tested it", and drawing it would extend
a decode past the case it was fitted on. pgloading_loop5's leaf is scale (0,0),
and scale-0 is one of the three historical failures this corpus names.

Neither can be adjudicated here: title_jp has no oracle capture, and
verify-screen compares against a renderer that draws no leaves at all, so ANY
leaf drawing increases that divergence whether right or wrong. Its max went
155 -> 232 when they were drawn, and that number is not evidence in either
direction.

9ad8f63234 port: the exporter never opened an element's own .rat leaf -- 45 elements, and the title's 1.82%
The Decoder overturned the elimination I was most confident about. I ruled out
the ptloop sweeps because "399x180 at (441,270), keyframes hold position
constant". That is the PARENT's record. The geometry is in the leaf.

  ptloop01  parent: scale (100,100) rot 0, fixed at (441,270)
            LEAF:   scale (100,600) rot +30, x sweeping -639 -> -39 -> 1521
  ptloop02  parent: scale (100,100) rot 0, fixed at (441,270)
            LEAF:   scale (100,800) rot -45, x sweeping 1721 -> 1111 -> -839

Two ~1080 and ~1440 px quads leaning opposite ways and sweeping across the frame,
against two 400 px sprites drawn upright and static in the middle. That is
exactly the signature I measured -- darker centre-left, brighter right, nearly
cancelling -- and the GPU capture puts their centres at x ~ 467 and 992, the two
cells where my signed difference peaked.

`ui_layout`'s own doc comment said it: "the rotated quads come from its two
nested .rat leaf records, which the census never opened". Neither did this
exporter -- it opened a leaf in exactly one place, `highlight_name`, for focus
records.

IT IS NOT TWO ELEMENTS, IT IS 45: every button on every menu (the benign case,
where screen.rs already knew the leaf duplicates the parent and the parent wins),
the four loading screens' pgloading_loop*, and title_jp's ptlogo_eff2 -- which is
the element DECISIONS has recorded since P1 as the largest render disagreement in
the export, and which has a TWO-element leaf. A lead, not a conclusion.

EMITTED, DELIBERATELY NOT DRAWN. One `read_leaf` closure serves both the new path
and the focus path, because a second copy is how this would go missing again.
ScreenView ignores the data: parent and leaf each carry their own alpha ramp over
a different span (parent 0->255 over t=70..238, leaf 255->0x80->255 over
t=150..600), so how they compose is a decoding question, and drawing on a guess
would replace a visible 1.82% gap with an invisible wrong one. verify-screen
confirms nothing moved.

Additive blending is refuted -- the Decoder tested T8aD +0x04 bit 0x02 and "every
measure worsens", and the export carries no blend field because none has been
found (no RB_BLENDCONTROL in the per-draw capture). My hypothesis from last
iteration is dead.

This makes the port's biggest oracle gap the same item as the rotation question
already standing with the human: sylpheed-cli deliberately does not rotate, which
is why both renderers show it, and MISSION's "Needs a human decision -- rotation"
now has a number: 1.82% of the title's pixels.

e35c9453b7 port: S00A is closed as not obtainable, and Q5's shape is tighter than "unstable"
Three things folded in from the Decoder, none of which change the export.

S00A IS NOT OBTAINABLE HERE and it is the game that stops it, not the drive. The
drive works end to end -- main menu +0.999, newgame-difficulty +0.999,
newgame-selectdata-crash +0.997, with the focus detector validated live against a
known transition rather than trusted -- and then the guest throws at
PC: 0x82307128 x349 with no S00A stream ever decoding. Recorded in BLOCKED as a
route finding, with the consequence for me stated: THE CENTRE-CHANNEL RESULT
RESTS ON ADV ALONE. S00A was wanted precisely because its second stream is
digital silence where ADV's is a 0.60x copy.

Q5 GAINED TWO POINTS and the shape is sharper than "it varies": TUTORIAL x3, NEW
GAME x3 over six boots, and no other item ever observed. That does not change the
port's authored initial focus -- NEW GAME is still one of exactly two observed
states and is the state of the committed capture -- but it changes what would
REFUTE it, so the authored `why` now says so: a boot opening on LOAD GAME,
OPTIONS or EXTRAS breaks the two-way shape, and a rule predicting the split
deletes the entry outright.

`which-focus` NEEDS GODOT AND THE EXPORT TREE, so it cannot run in the RE
container. Recorded in its own header rather than left for the next agent to
discover, along with the pointer to the capture-only alternative and that tool's
own caveat: its offline controls are its calibration inputs, which is
self-consistency and not validation.

c1edd13848 port: the title residual is a horizontal redistribution, and three of my own explanations are dead
`title` is the port's largest disagreement with the oracle at 1.82%, and last
iteration I attributed it to the moving ptloop sweeps without checking. Wrong,
and so were the two hypotheses I formed after it.

NOT THE SWEEPS. ptloop01/02 are 399x180 at (441,270) -- small and central -- and
their exported keyframes hold pos, scale and rotation constant. The difference
peaks at x~1088.

NOT AN OVER-HELD ELEMENT. Added `--no-hold` to render the alternative: playing
the title's groups past rest fades the screen to black by t=5.2 s, 30.97%
differing against 1.82% held. Holding at rest is right.

NOT A TIMING OFFSET. Sweeping the build-in gives 24.05% at t=1.6 falling
monotonically to 1.68% at t=4.18 and 1.82% settled. The capture is at the settled
end.

WHAT IT IS: a horizontal redistribution. Signed difference by cell shows the port
DARKER centre-left (-13.1, -8.3, -6.6) and BRIGHTER right (+16.0, +9.9), nearly
cancelling -- whole-frame means 63.8 against 62.5. Brightness in the wrong place,
not a level error or a tone ramp. It falls in the rows spanned by the two wide
elements ptlogo_back2 (1118x262) and ptlogo_back2eff (1133x280), with the column
profile falling off past x~1152 against their right edges at 1189 and 1197.

AND THE EXPORT CARRIES NO BLEND MODE. ptlogo_back2eff's keys are declared, id,
index, keyframes, kind_raw, layer, layer_source, pivot, rest, role, sprite --
there is no blend field, in this element or in FORMAT.md at all, and the port
composites everything with normal alpha. If the game draws `_eff` layers
additively, a wide gradient sprite would produce exactly this signature and
nothing in the export would reveal it. Asked, not assumed; I have not tested it,
and I am recording it because the three I could test are dead.

Recorded and NOT acted on: pteff02's rest.t is 46, where its fade is 25% black,
while its own group reaches 0x00000000 at t=236 -- so the port holds a black veil
the timeline removes. Third instance of rest.t naming a hold that is not the
settled state. It does not explain the residual: removing a darkening veil would
make the port brighter still, and it is already brighter where it disagrees.

`--no-hold`'s first version set the flag thirty lines before `view` exists and
silently rendered nothing, caught because the loop found no files rather than
because anything reported an error.

28d90449e6 port: which-focus -- a focus detector for the Decoder, with the control wired in
S00A is blocked on knowing which button a screenshot has focused.
`newgame_path.sh` assumed NEW GAME at boot, drove on it, and landed in a tutorial
mission -- HANDOFF Q5 measured focus as UNSTABLE across boots. Counting presses
cannot substitute: up from the first item wraps to the last, so no fixed number
of presses lands on a known item from an unknown start.

The Decoder's own attempt, a per-row brightness statistic, FAILED the control --
it picked NEW GAME on the capture whose filename says OPTIONS. The
render-difference method passes it, so this packages it as a script.

IT RUNS THE CONTROL ON EVERY INVOCATION, not once when it was written, and
refuses to report anything if the control fails.

  live-main-menu-options-focused  KNOWN ANSWER      OPTIONS         4.7x
  live-main-menu                  the question      NEW GAME       11.4x
  live-extras                     KNOWN from corpus MISSION SELECT  4.2x
  live-title-press-a              no menu at all    refuses         1.0x

The extras row is a second known answer I did not plant -- authored/flow.json
already records "MEASURED: EXTRAS opens focused on MISSION SELECT
(live-extras.png)" -- and the tool reaches it independently. The title row is the
negative control.

AND THE REFUSAL NOW CARRIES A NON-ZERO EXIT CODE. The first version printed "do
not act on this" and exited 0, so a caller scripting it -- which is the entire
point -- would have read a refusal as an answer. Same defect as a checker
claiming a check it skipped, and the fifth instance of that shape this session.

What it is not: it identifies focus in ONE FRAME and says nothing about what
selects focus. Q5's instability stands.

4e249d9d63 port: the capture has NEW GAME focused, and my harness had been rendering no focus
The Decoder attached an honest caveat to its reproduction of the tone-curve
refutation -- its bins included the focus-state mismatch, so it was "not a clean
second opinion". Removing that caveat found a defect of mine.

IDENTIFYING THE FOCUSED BUTTON, with a known-answer control. Walking focus
through all five buttons and comparing each against a capture:

                    vs -options-focused    vs live-main-menu
  ptbtn01 NEW GAME        6351                   531
  ptbtn02 LOAD GAME       7087                  7094
  ptbtn03 TUTORIAL        6230                  6237
  ptbtn04 OPTIONS         1292                  6364
  ptbtn05 EXTRAS          6073                  6080

The control picks OPTIONS by 4.7x -- the answer its own filename gives -- so the
test is trustworthy, and live-main-menu.png has NEW GAME focused by 11.5x. That
is what the port already focuses. Corroboration, NOT a decode: Q5's instability
stands (four boots gave TUTORIAL, TUTORIAL, NEW GAME, NEW GAME) and this
identifies one frame rather than a rule. Recorded in the authored entry.

THE DEFECT: `verify-capture` rendered menus with `--screen=`, which draws no
focus record, so it had been comparing main_menu to the oracle in a state the
oracle was never in.

  main_menu  0.25% differing, RMSE 14.79  ->  0.06%, RMSE 13.21
  extras     0.46%, RMSE 15.29            ->  0.20%, RMSE 13.38

A 4x improvement that was entirely my harness posing the port wrong rather than
the port drawing wrong. The first run of a new correctness harness reported a
discrepancy and three quarters of it was the harness.

AND THE DECODER'S CAVEAT RESOLVES TO NOTHING, measured rather than assumed:
re-deriving the transfer curve on the correctly-posed pair gives 1.20 / 1.26 /
1.18 / 1.10 / 1.03 / 0.94 at render 8..48, unchanged from the mismatched run. Its
reproduction stands as a second opinion after all.

ca23a5479a port: build the correctness harness verify-screen has pointed at since P1
`tools/port/verify-screen` line 20 has said "use `tools/verify-capture` for the
correctness question" since P1, and there was no such file. The port has had a
harness comparing itself to sylpheed-cli -- two renderers sharing its assumptions
-- and none comparing it to the game, while its own docs said otherwise. That gap
is what ORACLE-CAPTURES.md warns about: this corpus has been bitten three times
by two renderers agreeing, and every one was obvious against a capture.

Five screens against framebuffer captures of the real game:

  main_menu        RMSE 14.79   0.25% differing   focus state may differ
  extras           RMSE 15.29   0.46%             focus state may differ
  title            RMSE 21.07   1.82%             ptloop sweeps never stop
  publisher_logo   RMSE 10.77   1.00%
  developer_logos  RMSE  9.37   0.39%

NO SCREEN SHOWS A LARGE CONNECTED BLOB -- the shape a missing element makes, and
the shape all three historical failures made.

And 74.1% of main_menu's differing pixels fall inside the ORACLE'S OWN focus
signature (live-main-menu vs live-main-menu-options-focused, the same screen with
a different button lit). So the bulk of that disagreement is a state mismatch,
not a defect.

REFUTATION ATTEMPT, on ui-render-tone-curve.md's `capture = 255*(render/255)^g`.
It survives where it was measured and not past it. Binning every structurally
matched pixel by render level gives the relationship directly, and the implied
exponent is NOT constant: 1.26 at render 16, 1.10 at 32, crossing 1.0 near 44,
down to 0.69 at 96. Above ~44 the capture is BRIGHTER than the render, which one
exponent cannot express -- and that is exactly why my whole-frame fits kept
returning 1.00, the two halves cancelling. The page's own stated reach ("nothing
constrains midtones or highlights") was not a hedge, it was the finding. Its 1.49
for this screen measures 1.18-1.26 in my darks; recorded as a disagreement rather
than resolved, since they fit selected flat patches and I binned everything.

Two earlier versions of this tool reported a best-fit gamma and were wrong both
times -- once fitting across a 74% structural mismatch, once extrapolating past
the measurement's stated reach. The fix was not a better fit but a different
instrument: it prints the curve, which somebody can argue with.

33bb50e80d port: stripping driver padding is exact -- the gate on S00A is cleared
The Decoder made this the gate on S00A and that was the right order: ADV plays
itself on boot and can be captured with --gpu=null at 0.96x real time, but S00A
starts ~4.5 s after (A) on a save slot, which needs a driven run, which needs
screens, which rules out --gpu=null. So S00A is necessarily the 0.70x rendered
route with ~10% additive padding, and is only worth a boot if stripping is exact.

It is. A real music+SFX bed -- 137.37 s, carrying 454 genuine zero runs of its
own -- had 1149 holes inserted at 8.37/s to +9.9% length, matching the observed
ALSA profile, then was stripped and correlated in the low band:

  original vs itself      r 1.000  lag   0.0 s  margin +0.141   ceiling
  PADDED   vs original    r 0.436  lag -12.2 s  margin +0.006   destroyed
  STRIPPED vs original    r 1.000  lag   0.0 s  margin +0.142   recovered
  stripped vs orig-also-stripped   r 1.000      margin +0.143

Two things worth reading off that. Padding at that profile destroys correlation
completely -- r 0.436 in the known-absent regime -- which independently confirms
on a file whose contents I control that the earlier captures were unusable for
the reason claimed and not for some other one. And recovery does NOT require
stripping both sides: the stripped capture matches the UNSTRIPPED source at the
ceiling, so the port's reference assets never need touching.

`tools/port/strip-padding` implements it, and its header leads with when the
operation is vandalism rather than with what it does: PulseAudio's monitor
SUBSTITUTES silence and deleting those holes repairs nothing, while Xenia's ALSA
writer PADS and removing that is exact. Running it on the wrong artefact would
look like it worked.

Its output is byte-identical to the control's own stripping, so the tool and the
experiment are one operation rather than two implementations that agree.

Not licensed by this: stripping removes genuine silence too and cannot tell them
apart. Here the genuine runs total 0.71 s in 137 s and cost nothing measurable;
on material that is mostly silence they would.

c1eb3c60cd port: the oracle speaks -- the exported voice IS the game's centre channel
The Decoder's fourth capture is the first faithful one: --gpu=null takes the guest
from 0.70x to 0.96x real time so Xenia stops padding, and an ALSA `file` tee in
front of a paced slave removes PulseAudio's wall clock entirely. 59.7 s, 0.35%
silence, ONE gap in the whole file. Checked here rather than taken: it passes
check-capture, and its header sizes verify exactly.

The correlator was already calibrated, so this was a re-run and not a rebuild.
Controls on this instrument first: known-present margin +0.248, absent +0.005.

SPEECH BAND, margins by channel:

                        FL      FR      FC      LFE     RL      RR
  stream 1 (leading)   +.013   +.006   +.012   +.009   +.012   +.005
  stream 2 (EXPORTED)  +.238   +.171   +.305   +.011   +.035   +.006
  stream 3             +.240   +.173   +.307   +.009   +.054   +.006

r = 0.989 on FC, margin +0.305, above the known-present control. And the bed in
the low band is the mirror image: FL .763 / FR .838 / RL .805 / RR .817, all on
the same lag, FC .317.

SO: the dialogue is in the centre channel and the bed is in the four corners --
measured, where the header could never have said it, since ChannelMask reads
0x0002 on all three streams. And the port's exported voice file is the material
the game plays in FC: the `loudest` choice, which I recorded as unjustified,
selects the dialogue.

WHAT THIS DOES NOT SAY. Streams 2 and 3 are indistinguishable to this instrument,
exactly as expected from stream 3 being 0.60x stream 2 with the residual 26.8 dB
down -- so this does not say `loudest` picked the right one of the two, only that
whichever it picked is the dialogue. Stream 1 is undetectable here, consistent
with being stream 2's tail and a window that starts before it.

The `1 of 3 streams` warning STAYS: nothing here explains what the other two
contribute. What changed is its character -- from "one of three, contents
unknown" to "the centre-channel dialogue, plus two streams whose relationship to
it is measured and whose role is not".

Reach: 59.7 s of a 137 s movie, one run, 0.96x real time, and no screen
provenance -- --gpu=null costs video, so provenance is the XMA probe showing
ADV's three streams decoding during the run.

78879dce06 port: check-capture refuses a format it cannot read, and accepts the one it nearly rejected
The Decoder is moving to an ALSA `type file` tee, which writes float32. Read as
s16 that yields a plausible-looking file whose only tell is per-channel peaks
alternating exactly -- the two halves of each float landing in alternate
channels. My parser assumed s16 throughout and would have mis-read it
confidently.

An unreadable format now ends the run at PARTIAL (exit 2) rather than PASS:
channels were checked, starvation was not, and the tool says which. A checker
that claims a check it skipped is the shape of every failure this file documents.

AND THE FIRST VERSION OF THE GUARD WAS TOO STRICT -- it rejected one of this
tool's own controls, a six-tone file `ffprobe` correctly calls pcm_s16le, because
the file is WAVE_FORMAT_EXTENSIBLE (tag 0xFFFE) rather than plain PCM. A format
guard that refuses a legitimate capture is the same defect as one that mis-reads
an illegitimate one, pointing the other way. The check turns on wBitsPerSample,
which is what decides the layout; a float tee is 32-bit and still caught.

Control sweep, now the tool's real specification and all of it runnable here:

  real music+SFX bed                        PASS
  voice track, mono, 53% real pauses        PASS
  six distinct tones, PCM and extensible    PASS
  bed with 350 ms holes punched in          FAIL
  the starved capture                       FAIL
  the same tones as float32                 PARTIAL

the renderer because it has a disc-wide check: 16 of 212 elements match its shape
and all 16 are focus rings. The analogous shape for a pulse -- keyframes varying
only in alpha, first alpha equal to last -- matches 82 OF 212, including
ptcopyright, palogo_sqex, ptmsg and every _eff fade. A renderer rule on it would
make the copyright notice pulse. Narrowed to focus records it matches exactly one
distinct element, and a rule justified by n=1 is a special case wearing a rule's
clothes.

So it is a LOOKUP in authored/timing.json keyed <screen>/<element>, with the
census recorded beside it so nobody widens it later.

The period is 129 units -- the element's own group under the port's existing
model: last timed keyframe t=105 plus the authored exit_ramp_units of 24. No new
constant. 2.150 s at 60 units/s, 2.295 s at the ~28.1 fps the emulator presents,
against measurements of 2.12-2.34.

IT IS A CHOICE AND THE ALTERNATIVE IS STATED: restarting at the group's first
keyframe (t=6) instead of 0 gives 123 units = 2.050 / 2.189 s, also inside the
measured spread. Nothing separates them. t=0 is taken because it is where every
other group starts -- consistency, not evidence.

Verified the way the ring was, by bit-identity one period apart. 20 periods is
43.00 s = exactly 172 film frames: frames N and N+172 differ by 0-1/255, while
the control a quarter-second off (43.25 s) differs by 58.7/255. On the held boot
title the glow-box mean swings 26.0 <-> 37.7.

ba364dba5a port: check-capture needed two numbers -- the rate alone passed a 50%-silent file
The Decoder found a blind spot in the bar I shipped last iteration. Raising the
PulseAudio client buffer keeps cutting the gap RATE while total silence bottoms
out and then doubles -- an over-large buffer starves in a few enormous holes
instead of many small ones. Its 500 ms capture scores 1.3 gaps/s, better than a
genuine music bed at 3.3, while being 50% silence. My 20/s bar passed it.

Same shape as the level table that cannot see a duplicated channel: one number,
blind to the failure next door.

I did not set a bar on their numbers, because I do not hold those files and the
last two bars in this tool were wrong precisely from being invented. Instead I
built a control in that regime -- `bigholes`, a real bed with 350 ms holes
punched in -- and set the rule from four controls I can run:

  real music+SFX bed          1.1% silence,  3.3 gaps/s   PASS
  voice track, mono, pauses  53.2% silence,  0.3 gaps/s   PASS
  bed with 350 ms holes      46.3% silence,  3.2 gaps/s   FAIL
  the starved capture        35.6% silence, 30.9 gaps/s   FAIL

Rate alone cannot separate rows 2 and 3; silence alone cannot separate 1 and 3.
The pair does: fail when >=10% is silent on every channel AND there is at least
one gap per second. Real audio is either mostly not silent, or silent in a few
long stretches -- not both at once.

AND THE REGIME IT STILL CANNOT JUDGE IS PRINTED RATHER THAN PASSED. High silence
with very few gaps is what a real voice track looks like and what an
over-buffered capture looks like; nothing here separates them, so the tool says
UNJUDGED and tells the reader to check against a known source. Inventing a bar
for a regime with no control in it is how the previous two bars came to be wrong.

A CONTROL THAT DOES NOT EXECUTE IS NOT A CONTROL: the tool returned immediately
for single-channel input, so the mono voice track -- one of the four controls --
was never run through the check it was meant to control. Mono now skips only the
duplicate test.

Also recorded: the Decoder has withdrawn "the monitor-sink route cannot be fixed
by configuration". A ~200 ms client buffer is worth a retry BEFORE anyone spends
a session on a Canary rebuild.

57bb630c69 port: make the dwell comparison repeatable, and record that the settle run is unanchored
TWO THINGS, and the first is that nothing needed changing.

The Decoder withdrew one of the two legs under its settle-time run: the plate
pulse period it had offered as proof the run was not slowed rests on one interval
at a 125 ms sample rate, and re-picking the troughs gives 2.628 s rather than
2.369 -- an adjacent local minimum counted as a separate trough. It cannot
resolve a real-time factor below ~7%.

Nothing in the port moves, because the numbers that correction touches were
already unauthored. Checked rather than remembered: grep over authored/ and
port/scripts/ finds no 0.531 and no 0.482. The only build-in reference in the
tree is the plate arithmetic t=118 -> t=238, 120 units, which is the anchored leg
-- it agrees with three prior readings and with the disc's own declaration.

I had declined those two as one-run figures the Decoder itself flagged, with the
port already within ~0.1 s from the disc's keyframes. That reasoning now has a
second, independent justification I did not have at the time: a few per cent of
slowdown sits inside them undetected.

SECOND: `tools/port/verify-dwell`. Last iteration's hand comparison refuted a red
flag I had filed myself -- `rest.t` is the wrong settle landmark, but "everything
the sequencer paces off it is therefore late" was false and I nearly re-paced
screens that already matched the game to 0.05 s. That check existed once, in a
transcript. Now it runs.

Its header carries the trap it exists to prevent, because that is the whole
point: a port's TRANSITION TIMESTAMPS and the oracle's VISIBLE SPANS are not the
same quantity, and differ by the exit ramp plus the black hold -- about 0.6 s,
the entire discrepancy. The same confusion cost this corpus 0.48 s on the plate
delay.

The bar is the oracle's own run-to-run spread plus one film interval. Three cold
boots of the real game differ by 0.3 s, so agreeing more tightly than the oracle
agrees with itself would mean nothing. The developer-logo span reads 3.50 s on
the hand-run and 3.75 s here, one interval apart and both inside the bar -- the
tool reporting its resolution rather than hiding it. The oracle's numbers are in
the script as a labelled test fixture citing their RE document; nothing in the
port derives them.

dd39a4eb09 port: BLOCKED -- the voice row says the capture routes are closed and why
The row still asked for a capture through the PulseAudio null sink as the thing
that settles it. Both routes are now closed: take 1 was corrupted by a
channel-map remap, take 2 is starved by construction, and the monitor sink cannot
be fixed by configuration -- it advances at wall-clock rate and substitutes
silence. The route that works needs a Canary rebuild costed at a whole session,
which is the human's call.

Also records the withdrawal of the WMA-track concern: a starved file neither
supports nor refutes it.

c184a4f8ab port: check-capture passed a file that was 36% holes -- it now catches starvation
The Decoder diagnosed take 2 as a STARVED capture and I verified it here rather
than take it on trust: 35.6% of frames silent on all six channels, 10482
alternating runs, median burst 13.5 ms and gap 3.9 ms, a 17.4 ms period at 57 Hz.
Their untruncated original reads 39.3% and 10595 runs; the difference is exactly
the truncation and every other number agrees.

So my rebuilt correlator was working correctly on a file that could not carry the
signal. The alarming reading it produced -- that the game may not play the .wmv's
WMA track, so ADV.ogv's audio has been wrong since P4 -- is NOT SUPPORTED by this
capture and is not refuted either. Withdrawn as a concern arising from evidence,
with nothing changed in either direction. It was the most expensive-to-act-on
hypothesis in the port and it came from a file that could not speak to it.

THE REAL DEFECT WAS MINE: `check-capture` tested only for duplicated channels, so
it cleared a recording that was 36% holes. A provenance check that passes the
artefact it was built in response to is not a check.

It now measures starvation, and TWO THRESHOLDS I INVENTED WERE BOTH WRONG:

  counting exact-zero frames -- real audio crosses zero constantly, so a clean
    voice track scored 5947 "gaps" of median 0.0 ms and was called starved. A gap
    is a RUN, not a sample; only runs over 1 ms count.
  gap count and median length -- a genuine music bed shows 454 gaps at a median
    of 1.4 ms, because quiet 16-bit passages really are zero for milliseconds.

What separates them is the RATE: 32.9 gaps/s starved, 3.3 for a real bed, 0.03
for a voice track that is 53% pauses. Bar at 20/s, derived from those controls
rather than chosen and then justified. Controlled both directions: real stereo
bed PASS, six distinct tones PASS, starved capture FAIL. It also reports a `data`
chunk declaring 0 bytes -- what a file copied mid-write looks like, which is what
happened.

VOICE CHANNEL ROLES ARE NOT OBTAINABLE THIS SESSION. Both routes closed: the
monitor sink is starved by construction, and the internal tap at
SDLAudioDriver::SubmitFrame needs a Canary rebuild the Decoder has costed at a
whole session. That is the human's call, not an agent's. The port keeps authoring
with the known recorded.

ff04fbce52 port: the menu music was 3.52 dB quiet -- a bank header was being summed as a stem
Checking my export against the Decoder's declared XMA1 durations turned up a
defect of mine that has been shipping since P6.

`export_bgm` summed every sub-wave `media` returned and scaled by 1/n. Decoded
and timed, all three banks have the same shape:

  BGM_103  sub-wave 0: 10300 B -> 0.009 s, peak -inf   1: 87.744 s   2: 87.744 s
  BGM_102  sub-wave 0: 10300 B -> 0.009 s, peak -inf   1: 37.482 s   2: 37.482 s
  BGM_001  sub-wave 0: 10300 B -> 0.009 s, peak -inf   1: 173.809 s  2: 173.809 s

Sub-wave 0 is DIGITALLY SILENT in all three, and 10300 B is 10240 plus a 60-byte
RIFF wrapper -- 10240 being exactly the bank header the Decoder's census
identifies. Counting it in the divisor put every real stem at 1/3 instead of 1/2:
3.52 dB on all the menu music since P6. Dropping a silent input is arithmetic,
not a decoding decision. Measured after: main_menu.ogg -7.69 -> -4.20 dBFS,
+3.49 dB against 3.52 predicted.

THIRD INSTANCE OF ONE DEFECT: a silent chunk in the voice sum, a silent channel
in the mono fold, now a silent sub-wave in the music sum. Each invisible to every
check except a level, and each time the divisor was computed from how many inputs
there are rather than how many carry signal. That is the shape, not the bug.

Closes a red row open since P6 -- "sound_bank_riffs returns three sub-waves where
Q10's census says two". The census was right, and this corroborates the Decoder's
c1f3608 by decoding rather than by counting headers. The export reports 2
sub-waves and the warning is gone.

REFUTATION ATTEMPT, conclusion survives and the reasoning does not: the Decoder
explained BGM_001 as "173.821 s declared against your decoded 167.663 s, a gap of
6.158 s -- declared is the encoded stream, decoded is where the audio stops." A
full decode yields 173.809 s of PCM, not 167.663. The 167.663 is where the music
FADES OUT, measured from the audio; the stream continues silent to its declared
end. Declared and decoded agree to 12 ms, and the trailing silence is inside the
decode rather than the difference between two methods. The cross-check is
stronger than stated -- three banks, 5-12 ms -- and the explanation should go.

6210c2e131 port: my correlation instrument failed its own control -- the negative had to be re-earned
Take 2 is a good file: it passes check-capture (I re-ran it rather than cite the
Decoder's run), carries a screen log, and was recorded with the sink's
channel_map set equal to Canary's own.

BEFORE REPORTING A SECOND NEGATIVE I ASKED WHETHER MY METHOD COULD DO THE JOB,
by building a synthetic mix -- the bed plus the three voice streams -- and
hunting the bed inside it. It failed: r=0.415, against the r>0.8 bar my earlier
negatives were judged against.

So the instrument that produced "the capture contains no ADV audio" could not
have found ADV audio in a mix even when it was certainly there. That conclusion
was right -- the Decoder's tone control proved take 1 corrupt independently --
but it was right BY LUCK and I reported it as measurement. The three controls I
was pleased with tested that the method finds a clean signal in a clean
reference, which was never the task.

REBUILT AND CALIBRATED IN BOTH DIRECTIONS. Band-limit so the target dominates,
then judge on LAG and MARGIN rather than absolute r -- r>0.8 is correct
clean-against-clean and meaningless for a component in a mix.

  bed, 40-180 Hz    in a mix containing it   r=0.663  lag 0.0 s   margin +0.111
  bed, 40-180 Hz    against a voice-only mix r=0.262  lag wrong   margin +0.005
  voice, 300-3000   in a mix containing it   r=0.810  lag 0.0 s   margin +0.248
  voice, 300-3000   against the bed alone    r=0.358  lag wrong   margin +0.005

A 20-50x separation in the discriminating statistic. Written up as
AUDIO-VERIFICATION.md section 6, retraction included.

THE NEGATIVE NOW STANDS ON SOMETHING. All six of take 2's channels, against both
targets, sit in the known-absent regime: margins 0.000-0.017, lags scattered from
-72 to +255 s. Take 2 contains neither the movie's WMA bed nor the cutscene
voice.

Two captures, differently configured, the second provably free of the channel-map
fault, with a screen log saying the movie was on screen, and neither carries
either source. Handed back: a capture path still losing the mix, or the guest not
emitting these sources during the movie, and only one side of the wall can tell
those apart. If it is the second it reaches the port directly -- the export's
movie audio comes from the .wmv's WMA track.

Also noted: the message gives 253.3 s, the file is 318.539 s. The screen log
agrees with the file, so it is a mis-stated number, but a length quoted in a
provenance claim should match the artefact.

f23180c4eb port: a capture must pass a provenance check before anyone analyses it
The 6-channel capture I spent an iteration refuting was corrupt, and the Decoder
found the cause: PulseAudio remapping between two mismatched channel maps, where
a 6-channel remap SILENTLY DROPS AND DUPLICATES. Its control -- six channels, six
tones, same sink, same parec -- came back 400/3200/200/800/800/200 for an input
of 400/800/200/1600/3200/6400. Two source channels gone entirely.

So the negative was right, and the byte-identical pair I reported was the thread
that unravelled it. Worth recording precisely, because it nearly went unreported:
it began as an idle look at two channels whose peak AND RMS matched to six
decimals, and it only became evidence because a coincidence at six decimals is
cheaper to hash than to explain.

`tools/port/check-capture` makes that check one command -- split the file, hash
every channel, fail on any duplicate pair -- and AUDIO-VERIFICATION.md gains a
section 5 saying to run it FIRST, every time, plus the two conditions the same
incident produced: start the recorder before the process, and log what was on
screen against the recording's own clock so a miss is diagnosable.

Controlled both directions, because a checker nobody controlled is what this
incident is about: six distinct tones PASS; the remap's own output pattern FAILS
naming all four pairs; the corrupt capture FAILS on ch2 == ch5.

THE KNOWN-BAD CONTROL IS THE POINT. All six of its channels report a peak of
-18.063656 dB, identical to six decimals, while containing three duplicate pairs.
A level check cannot see this failure. That is why the tool hashes rather than
measures, and why the corrupt capture's "plausible per-channel levels" were never
evidence. The tool says of itself that it is necessary, not sufficient.

Withdrawn with the file, both the Decoder's: "all six channels carry signal", and
the non-zero-surround observation offered as weak support for 5.1. Unaffected:
the three-XMA-context concurrency result, read from the emulator's log rather
than the audio path, on two independent boots.

The corrupt file is dropped from the exchange so the next agent cannot pick it up
and repeat the work. Nothing in the export changed.

018e879907 port: the oracle capture does not contain the intro -- a controlled negative
The Decoder took the capture I asked for and described it as the full mix, the
movie's WMA track plus the three XMA streams. It contains none of them.

Envelope cross-correlation, sliding with overhang, normalised over the overlap,
minimum 30 s of overlap so a short window cannot win on an edge. Against the ADV
bed, against each of the three voice streams, against BGM_103 and against S00A,
every pairing is a PLATEAU rather than a peak: best-to-runner-up margins of
0.001-0.016. The margin is the number that matters, not r.

Three controls, because a negative from an uncontrolled instrument is worthless:

  the instrument finds matches on this data -- bed vs bed r=1.000 margin +0.115,
    voice stream 2 vs stream 3 r=1.000 margin +0.300;
  my reference really is the movie -- the .ogv transcode against the disc's own
    ADV.wmv, r=1.000 margin +0.114, so a miss is not my transcode;
  drift is excluded -- a stretched playback would still match locally with the
    best lag climbing monotonically, and 5 s windows give 4.95, 15.30, 119.35,
    50.75, 29.35, 83.95 s, scattered across the movie.

WHAT IT IS has been handed back rather than guessed. It is 70 s of something,
all six channels carrying signal at RMS about -27 dBFS, matching nothing this
port exports. Diagnosing it is the other side of the wall.

One measurement that may help: split as 5.1, channels 3 and 6 are BYTE-IDENTICAL
-- same MD5, not merely the same peak and RMS. An exact duplicate pair inside a
six-channel surround output is consistent with the Decoder's own warning that the
6-channel frame is Xenia's hardcoded kFrameChannelsDefault rather than the
guest's request, and weakens any reading of that file as evidence of a 5.1 mix.

THE VOICE EXPORT IS UNCHANGED: still one stream of three, still marked red in the
manifest, the console line and authored/audio.json. A failed measurement should
change nothing, and what would have been wrong is treating an expensive recording
as an oracle because it was expensive.

8fba7944d4 port: the game decodes all three voice streams at once, and two baseline rows were comparing blank frames
TWO FINDINGS, one mine and one handed to me, and the second retires a premise I
built on twice.

THE P1 BASELINE HAD ROWS THAT PROVED NOTHING. `build_12` and `build_15` render
pure black in BOTH renderers -- mean 0, max 0 -- so the difference is zero and
`verify-screen` scored them `max 0  over3 0  OK`, the strongest verdict it has.
Two of sixteen rows were comparing nothing against nothing. Worse than a missing
test, because a missing test is visible in the count.

Cause isolated by a control, not by reading: `build_00`/`build_01` are the same
loading screen minus three elements and render fine (mean 1.913, max 214.5). The
dressed variants add `pgloading_eff00`, a 1280x720 primitive resting OPAQUE BLACK
at t=38 inside its own opening black hold, with no layer key so paint order puts
it last.

The rule I was about to write -- "rest.t before the last timed keyframe is the
pathology" -- was killed by running the census first: 152 of 212 elements in this
export have rest.t earlier than their last timed keyframe. It is the norm. What
is actually unusual is the CONTENT, and its reach is one: `pgloading_eff00` is
the only element in the export whose resting pose is a fully opaque full-frame
quad. One instance is not a rule, so the renderer is unchanged and the HARNESS is
fixed: a blank pair now reports BLANK -- both renderers drew nothing; this row
proves nothing. `status` is untouched, so an unrelated DIFFERS still fails.

THE VOICE EXPORT IS KNOWN INCOMPLETE. The Decoder booted Canary with
--xma_param_probe and the game decodes ALL THREE streams CONCURRENTLY, in three
XMA contexts whose byte sizes match the disc payloads exactly. So "three
presentations of one take, pick one" is refuted by the running game and the
question I had been arguing -- WHICH presentation -- has no answer.

This one no census could have caught. Every measurement was right: the streams
are equal-duration, one is silence, one is 0.60x another with the residual 26.8
dB down. The frame around them was wrong, and the file says ChannelMask 0x0002 on
all three. It took the running game -- which is the mission's own sentence
arriving in practice.

BEHAVIOUR HELD DELIBERATELY. An equal-gain 1/n sum of channel pairs is not a
downmix either -- MISSION section 6 pins an explicit matrix for exactly that
reason -- and summing cost S00A 6.02 dB when one stream was silence. Swapping one
guess for another on a message is what produced this entry twice. What changed is
that the wrongness is now LOUD, because this failure sounds like success: one
stream is clean audible dialogue. A top-level manifest warning per movie, the
console line, and the authored entry all say `1 of 3 streams`.

"They are 5.1" is recorded as the Decoder's HYPOTHESIS with its own
counter-evidence attached, and nothing builds on it. What settles it is asked: a
recording of the game's own output over ADV through the null sink, which turns
channel roles into a fit against an oracle.

Refutation attempt, survived: the Decoder's loading-screen variant map. Entries
0/1 carry 7 elements and 12/15 carry those seven plus baseeff, eff00 and loop5 --
exact in count and identity, and it is what made build_00 a control.

c43d44f57e port: withdraw the dual-mono generalisation -- the measurement stands, the rule does not
I argued `highest_rate` had no case because ADV's higher-rate presentation is
dual-mono while its louder one is mono-in-stereo, so the extra bytes buy a
duplicated channel rather than fidelity. The Decoder tested that disc-wide over
the 28 three-stream cues: the stream-3/stream-2 size ratio runs min 0.0778,
median 1.2565, max 2.9163, sd 0.5057, with only 12 of 28 within 15% of 1.0, and
declared rates scatter with them. A 37x spread is not a duplicated channel.

The CHANNEL MEASUREMENT STANDS -- ADV chunk 1 is mono-in-stereo and chunk 2 is
dual-mono at -8.318574, this port's own decode, which the Decoder could not
re-run and did not dispute. What fails is the step from one asset to the format.

NOTHING IN THE EXPORT CHANGES. `loudest` is a per-asset content rule -- it reads
the peak of the streams in front of it -- so a scattering structural ratio cannot
undermine it. What changes is the REASON, in four places: authored/audio.json's
presentation_why, the selector comment in audio.rs, BLOCKED.md's row, and
DECISIONS.md. The honest statement is narrower: `highest_rate` was never refuted,
it was never argued for, and neither is `loudest`. That is why the entry is
marked CHOSEN rather than measured, and why one capture deletes it.

Recorded on the pattern rather than just the instance: this is the third claim of
mine in two iterations that generalised a single-asset observation, after "the
chunks are two stems" and "everything the sequencer paces off rest.t is late".
All three were true of the thing I looked at. The failure is reaching for the
rule a measurement would imply if it held everywhere and writing that down in the
same breath as the measurement.

Also noted, not mine and not affecting export_voice: S12B's three streams are
byte-size identical, and BIRD_224 is three-stream while not being a movie cue.

2939c21b38 port: settle times measured -- the pacing was already right, and my own red flag was half wrong
THE TRANSCODE CACHE HAD NEVER HIT. `video::transcode` has carried one since P4 --
a `.cmd` sidecar with the command, the source size and the channel count -- and
`main.rs` clears the output tree wholesale immediately before the check, deleting
the sidecar and the file it stamps. Six exports in this session paid the full
Theora encode and produced five byte-identical files, roughly 48 minutes. Nothing
reported it, and nothing could: a cache is silent either way and the only symptom
is a wall clock that looks like the job being slow. The wipe now spares `video/`
and `prune_videos` deletes anything in it this run did not claim, so the
wholesale guarantee is kept rather than traded. A re-export is 20 s.

SETTLE TIMES, MEASURED, and they refute more of my row than they confirm. The
principle holds -- the title's rest.t is 251 units = 4.183 s where its art
finishes at ~2 s -- but "everything the sequencer paces off that landmark is
therefore late" does not. Measured the port the way the game was measured, by
VISIBLE SPAN rather than arrival-to-arrival:

  publisher wordmark  port 4.25 s   game 4.297 / 4.604 / 4.370
  developer logos     port 3.50 s   game 3.508 / 3.503 / 3.366
  black hold          port ~0.25 s  game 0.2 - 0.3
  title -> plate      port 2.000 s (declared 120 units)   game 2.247 s

Dead on. My earlier reading compared the port's transition timestamps against the
game's visible spans, which differ by the exit ramp plus the black hold -- the
whole of the discrepancy I was about to chase, and the same definitional trap
that cost this corpus 0.48 s on the plate delay. Nothing in the sequencer is
changed. `dwell_seconds` stays null, now for a measured reason rather than an
absent one: `timing.json` said "if a capture ever times the real boot, this is
where that number goes", and the answer is that nothing goes there.

Not authored, deliberately: an (A)->menu dwell, which measures 3.763 s and
contains a 1.53 s guest load stall on a cold cache; and the menu build-in and
(B)->title, which rest on one run where the port is already within ~0.1 s.

THE VOICE PRESENTATION MOVED TO authored/, because the recommendation behind it
was withdrawn as self-contradictory and the choice is now unambiguously mine.
`voice.presentation` = `loudest`, and the reason to switch is a measurement, not
a preference: ADV chunk 1 is MONO-IN-STEREO and chunk 2 is DUAL-MONO, so chunk
2's extra bytes encode a duplicate channel rather than fidelity. That explains
the byte-rate difference and removes the only argument for `highest_rate`. ADV's
dialogue now exports at +0.3 dBFS instead of -8.7, which is the SE bound's
documented decode overshoot on a wave mastered at full scale.

29fd735b96 port: a voice region is three presentations of one take -- keep one stream, sum nothing
Third reading of the same bytes in one session, and the first one that is
decoded rather than inferred.

  1. concatenate  -> 359 s of dialogue for a 137 s movie. Dead on measurement.
  2. sum as Q10's two stems -> refuted here: S00A's second full-length chunk is
     DIGITAL SILENCE and ADV's is 0.60x the first with 26.8 dB of residual. That
     claim was mine, and the Decoder had already adopted it before I tested it;
     it is withdrawn in both places.
  3. keep ONE stream. Decoded disc-wide by the Decoder, counting stream starts
     inside every inter-descriptor span: 258 spans hold one stream, 28 hold
     three, nothing holds two. So 359 = 84.55 + 137.32 + 137.32.

Summing was therefore wrong a third time, and for a third reason: a take plus a
0.60x copy of itself is ~4 dB louder and coloured, not a mix of parts. The filter
is now `[0:a]anull` plus the mono fold -- no gain applied at all.

`check` moves `voice` off the strict peak bound as a consequence. It sat with
`bgm` because it was a sum this exporter produced; it is now a single wave off
the disc, mastered near full scale -- ADV's louder presentation measures +0.0003
dBFS at source -- so refusing that would be refusing the disc's own mastering.

The leading chunk is dropped as a DUPLICATE, not a truncation. It is this
movie's own dialogue (the Decoder, 17 of 17) and I measured it to be the TAIL of
the kept stream: sliding envelope correlation r=0.998 / 0.932 with the lag flush
against that stream's end, controls 1.000 self and 0.289 for a different movie,
confirmed in the sample domain at 16.7 / 23.2 dB of residual.

STILL OPEN, and flagged rather than absorbed: WHICH presentation to keep. Highest
byte rate is the Decoder's recommendation and not a decoded field, and on ADV it
selects the QUIETER of two (-8.3 dBFS against 0.0). Said in the manifest with the
consequence, so it is visible and reversible. A capture of the intro with
dialogue audible settles it.

Not converted, and the Decoder has since withdrawn the ask with a better reason
than mine: its 504464 B anchor constant is structural, not proportional --
identical on all 17 regions, and a proportional prediction lands within 8 bytes
on ADV while being 4305 B out on S00A.

0e7fcc2dda port: fold only the channels that carry signal, and measure what the leading chunk actually is
TWO DEFECTS AND ONE MEASUREMENT, all from verifying the previous commit rather
than from reading it.

Channel 2 of both voice streams is DIGITALLY SILENT -- peak -inf over the whole
file. The voice is a mono recording carried in a nominally stereo stream, and
averaging it with silence cost 5.94 dB. The doc comment directly above the code
that did it warned that "a stereo matrix applied to a mono voice track is not an
error, it is a -6 dB attenuation that nothing reports", and then the code checked
the DECLARED channel count instead of the content. `live_channels` now measures
which channels carry signal and averages only those.

Three defects this iteration were the same shape: a silent chunk in a sum, a
silent channel in a fold, and a pan matrix naming channels that do not exist.
Each is an input contributing nothing while still counting in a divisor, and none
is visible in anything but a level.

THE LEADING CHUNK IS THE TAIL OF THE FULL-LENGTH ONE. The Decoder settled by
byte-span analysis that it is the movie's own dialogue, 17 of 17 -- killing its
own hypothesis that it was an in-mission line -- and asked whether dropping it is
a truncation, having no XMA1 decoder. Sliding envelope correlation with overhang
allowed and normalised over the overlap: ADV r=0.998 at +52.8 s, S00A r=0.932 at
+25.6 s, against controls of 1.000 (self) and 0.289 (a different movie). Both
lags put chunk 0 flush against the END of chunk 1. Sample domain, lag refined to
one sample then a scalar best-fit: residuals 16.70 dB and 23.15 dB below target.

So dropping it removes a DUPLICATE and the exporter was right for a worse reason
than it gave. The manifest note is NOT rewritten to claim that -- the structural
conclusion belongs on the Decoder's page, not in my manifest -- but it no longer
equates the chunk with BGM_103's third sub-wave, which a disc-wide census showed
is a different structure, and it now says in words that the omission must not be
read as junk removal.

Not converted, deliberately: the Decoder's 504464 B anchor constant. Bytes per
second is not constant even inside one region -- chunk 1 is 1118268 B and chunk 2
is 1171516 B for the SAME 137.324 s -- so any figure in seconds off it would be
invented.

7465e49c8e port: withdraw my own "two stems" reading of a voice region, and stop summing silence
The Decoder asked me to decode a voice region's leading chunk -- it has no XMA1
decoder in its container -- and the decoder run refuted a claim of mine that it
had already adopted into `docs/re/structures/voice-region-leading-chunk.md`.

I wrote that a region's two equal-length chunks are HANDOFF Q10's decoded
two-stem shape. Equal duration was a SHAPE match and I carried the music census
across on the strength of it. The content does not support it:

  S00A chunk 2 is DIGITAL SILENCE -- 4497300 samples, peak -inf.
  ADV  chunk 2 is 0.60x chunk 1, best-fit scalar, residual 26.8 dB below the
       target: about 95% of its energy is a -4.4 dB copy of the first chunk.

That cost real level. Summing chunk 1 with silence at 1/n put S00A's dialogue
6.02 dB down for nothing -- the exported file peaked at -16.2 dBFS against a
source chunk peaking at -4.2. `export_voice` now drops a digitally silent chunk
before the sum, which is arithmetic and not a judgement about content.

WHAT ADV'S NEAR-DUPLICATE SECOND CHUNK IS REMAINS OPEN AND IT IS STILL SUMMED.
Whether the game plays both is a decoding question, 26.8 dB of residual is not
nothing, and dropping a chunk because it correlates with another would be
answering it.

The leading chunk, answered as far as a measurement goes: ADV region + 1392, 394
packets, 84.553 s, stereo 48 kHz, peak -2.48 dBFS, 6 silent gaps over 0.4 s
totalling 45.3 s -- 54% silence, the same duty cycle as the full-length chunks.
Speech-structured, so not a header and not padding. "Cutscene or mission" is an
identification and this agent has no ears and no oracle; envelope correlation
peaks at 0.768 at the last lag in the search range, which is where a statistic
lands when it has found nothing, and it is not an answer.

Not taken yet, and said so in BLOCKED: the discriminator should be
`bank_header_len`, not a duration tie. This exporter never used `riffs.len()`, so
it already handles both of the Decoder's cases, but a tie is an observation and
`bank_header_len` is decoded. It switches when `c1f3608` reaches `main`;
`sylpheed-formats` is a path dependency and merging another agent's topic branch
is not the port's to do.

18412e6324 port: the voice is in the mix, proved by a null control that needed no test code
Three things verified against the re-export, none of them by reading the source.

THE STEM READING IS CORROBORATED BY A NUMBER IT WAS NOT FITTED TO. Chunks are
selected as "the longest, and everything tying with it" -- the movie's own length
is not an input to that rule. The result now matches the picture to -0.114 s
(ADV) and -0.085 s (S00A), where the concatenated version was +221 s and +161 s.

THE VOICE REACHES THE MASTER BUS. `+ voice ADV` in the log proves only that a
stream was found and played. The control is MODDING rule 4: 140 s of silence at
data/mods/audio/voice/ADV.ogg shadows the exported file and changes nothing else,
so no test-only flag was added to the runtime. The muted run reproduces the
movie's own bed to 0.01 dB peak and 0.19 dB RMS; the unmuted run measures -22.913
dBFS RMS against -23.184 predicted for two incoherent sources at -24.941 and
-27.965. 0.27 dB out.

(A) SKIPS THE INTRO IN THIS BUILD. `--skip-at=25` ends the movie at 25.02 s
through `Input.parse_input_event` and `_unhandled_input`, so the press-to-skip
wiring is live and the play-test's report is not that bug. Untested here: a real
key from a focused window. Unsettled anywhere: whether the GAME permits skipping
an attract movie -- Q9, still amber, and if the answer is no this path is deleted
rather than debugged.

`check` accepts the new `voice` kind and holds it to the strict peak bound, with
`bgm`, because it is a sum this exporter produced rather than a wave off the
disc. FORMAT.md says what a `voice` entry is, that it keys by MOVIE NAME rather
than by a role, and that its `why` names every chunk dropped.

3aa74ea029 port: the intro had no dialogue because the voice is a separate asset, and I concatenated it wrongly first
A human play-test heard music under the boot intro and no voices. The obvious
reading -- the 5.1 fold dropped the centre channel -- is wrong. `ADV.wmv` carries
music and effects only; a cutscene's voice is a separate continuous XMA stream in
`sound.pak`, bound to the movie by the manifest in `tables.pak`. Nothing was
dropped. The exporter had never been asked for it, so every fidelity measurement
in AUDIO-VERIFICATION.md would have come back clean.

`audio::export_voice` resolves it with `media::resolve_movie_voice_region` and
never by filename: `RT01A`'s voice lives inside `VOICE_ADV.slb`, so a name match
is correct on exactly the two movies this port would have spot-checked. Decoded,
not authored -- so it runs outside the `authored/audio.json` block.

THE FIRST VERSION CONCATENATED THE REGION'S CHUNKS AND WAS WRONG. It produced
359 s of dialogue for a 137 s movie. Decoding and timing each chunk shows two of
them equal to six decimals and each spanning the whole movie -- HANDOFF Q10's
decoded two-stem shape on a second asset kind -- so they are summed at 1/n. The
error was visible only because the first version recorded the decoded length
against the movie's instead of clamping to it; the clamp `media`'s own doc
comment invites, and which `sylpheed-viewer` applies, would have produced a file
of exactly the right duration containing the wrong audio.

The dropped leading chunk matches no duration in its region and is NOT closed
here. It is the same signature as `BGM_103`'s third sub-wave, already open in
BLOCKED.md, now corroborated on an independent asset kind. Raised with the
Decoder; the manifest names every chunk dropped and its length.

Also in this commit, and separable:

* `--skip-at=SECONDS` -- `--script` structurally cannot press during a movie,
  because `_script_settled` waits while `_player != null`. That is why "does (A)
  skip the intro" had been read out of the source rather than measured.
* MISSION section 6 pins a 5.1->stereo matrix and this exporter has shipped a
  different one since P4 -- the same weighting, 7.65 dB quieter -- and said so
  nowhere. Re-measured with the right instrument (float decode, whole file, count
  the samples that would clamp, not a peak reading): the pinned matrix puts ADV
  at +4.26 dBFS on 4406 samples, while S00A never clips. So the pin overloads one
  movie and the constant is over-broad for the other. NOT changed -- the level of
  a mix is what section 6 reserves to a human. The export now carries a warning
  with the numbers.

16eef5fb2b port: file the keyframe-layout change and the loading-screen answer in BLOCKED
Neither is taken. The keyframe record layout (every pose timed, exit_ramp_units
decodable) reaches me only when that branch lands on main -- sylpheed-formats is
a path dependency and merging another agent's topic branch is not mine to do.
The loading-screen names are answered but carry two of the RE agent's own
amber flags plus the index-space problem I found, so no name is written yet.

Recorded with what limits the risk: static composites are byte-identical across
the keyframe change, so this iteration's verify-screen baseline is the control
to re-run the day the pin lands.

9bd7297757 port: the P1 regression harness could not have run since the monorepo merge
verify-screen resolves its reference binary to a path build-reference-cli
stopped being able to produce: that script greps Cargo.toml for a
`Syplheed-Reborn.git", rev = "..."` pin, and 9fbb352 replaced it with a path
dependency. The grep returns nothing, the script exits 1, and the binary left
behind predates the merge -- three hours older than the sources, from a revision
nothing points at. The consumer only checked that the file EXISTED.

DECISIONS already carries "the reference renderer was stale for three diff runs"
from P2. This would have been the fourth, by a different mechanism: not a
forgotten rebuild but a build step that could no longer succeed.

The fix is a deletion. Revision-keying solved a two-repo problem -- /reborn's
target/ was a live mount that moved mid-run -- and the monorepo removed that
problem by construction. verify-screen now builds sylpheed-cli from the
workspace, which is the same decoder the exporter and the port read.

BASELINE, all 16 screens, after four milestones of renderer change: no new
drift. The only substantial disagreement is title_jp (max 155, 20498 px), which
is the same one P1 recorded and left open -- ptlogo_eff2 at 125 % scale, where
blit samples the destination pixel's corner and a GPU samples its centre. The
port still does not match it, because matching means reproducing a half-pixel
bias on purpose to make a number smaller.

`max` alone could not tell 2 pixels from 25 000: main_menu and title_jp produced
the same DIFFERS verdict. The script now also reports how many pixels are over
the bar. The bar is NOT raised -- tuning a threshold until things match is the
failure its own header warns about.

Stated plainly because sixteen OK rows look reassuring: the harness renders
--pose=rest, so NONE of the last four milestones' visible work is under test --
not the spinning ring, not the plate composite, not any timeline behaviour, not
audio.

REFUTATION: the RE agent's answer naming "builds 0/1 and 10/11" as the loading
screen is false in the index space this export uses -- entries 10 and 11 are
palogo_sqex and palogo_gamearts, the splashes, which the same agent identified
as such answering my ask 1. Over the twelve is_build bundles, ordinals 10/11 ARE
entries 12/15, so the finding is right and the enumeration is not mine.
authored/screen_names.json is keyed by ENTRY, and someone writing keys "10" and
"11" from that message would name the publisher wordmark and the developer logos
as loading screens, and everything would still validate and run.

b37ad246ff port: implement MODDING rule 4, and withdraw a red flag that was my own bad measurement
MODDING.md calls base-and-overrides "a design constraint on the exporter today,
not a milestone to add later". Nothing read `data/mods/` at all -- the directory
has existed since the monorepo merge with a .gitkeep and no code path anywhere.
Eight milestones shipped past it.

ExportTree.resolve() now shadows by path, and every read goes through it:
screens, sprites, cues, the music bed, movies. MenuAudio was reading tree.root
directly and would otherwise have made audio the one asset kind a mod could not
touch, for no reason a modder could have guessed. No manifest, no registration
step -- the path IS the registration, which is the whole of the rule. One tree,
not a stack: layering needs a load order and nobody has asked for one, so
data/mods/README.md says that rather than inventing it.

Every shadowed file is printed as it is read. The first version summarised in
_ready, before any asset had been read, so it always said "nothing shadowed yet"
-- a report structurally incapable of reporting anything, which is worse than
none because it looks like an answer.

data/mods/ was NOT gitignored, and that is a hole in a hard rule: a mod is
usually an edited game asset, and this was the one directory a user is invited
to put modified sprites in and git would have taken them. Now excluded except
the README.

Gate: a synthetic 203x43 magenta PNG (nothing disc-derived) at
data/mods/sprites/title/main_menu/ptbtn01.png changes 8501 pixels in a bounding
box of exactly 203x43 at the button's position, and `check` still passes.

RAISED, NOT RESOLVED: MODDING.md says the tree is data/base/, PORT-MISSION.md §3
and the exporter and .gitignore say export/. Both are mission files and only the
human changes a mission.

REFUTATION on Q3's paint-order key: 2 of 16 screens did not match a stable sort
by layer key -- but that was my test. pgloading_eff00.prm carries NO layer key
(layer_source "none"): a primitive with no sprite header and no implied-name
fallback. I sorted keyless first; the decoders put it last, which is right,
since it is the full-screen black quad and HANDOFF's own sentence is that the
fade quad paints last. Completing the rule to "keyless last" gives 16 of 16.
SURVIVES. Recorded because the published claim does not say where a keyless
element goes and there is one in the archive. Separately the tie-break's reach
looks understated: 105 elements share a layer key across 12 of 16 screens, where
HANDOFF characterises the cost as "one element's blend on one screen".

WITHDRAWN, and it was mine: I filed "the runtime mix has no headroom" in red
twice, off a peak reading. Measured properly it is 43 samples at full scale in
5.9 s and 24 in 98.5 s, longest run 0.25 ms -- the disc's own confirm cue on a
transient, possibly only in the 16-bit save. Nothing changed, deliberately:
attenuating would be an unmeasured level decision of the kind I refused for the
loop point. A peak reading is not a clipping measurement.

The port's open asks have now been delivered by message three times and lost

dies with it. The asks themselves were never lost -- they are in this file, with
the HANDOFF sha each row came from -- but `docs/agents/decoder-loop.md`'s read
list does not name this page, so a fresh decoder has no route to it.

This does not fix that. It makes the page introduce itself, so that ONE pointer
at it is enough for a session that has never seen it, and states the gap plainly
where both agents and the human will read it. Changing the loop brief is the
human's call and I have not touched it.

7a6a027fc8 port: P7 -- the new-game intro plays, and the two screens it skips are named out loud
S00A has been exported since P4; what P7 needed was something to play it and a
defined place to land. Both are here, and the interesting part is the gap.

The real chain is NEW GAME -> DIFFICULTY -> SELECT DATA -> (A) on a save slot ->
~4.5 s -> S00A. DIFFICULTY and SELECT DATA are MEASURED destinations that are not
GP_TITLE builds, so no screen file exists to go to. The port jumps from NEW GAME
to the one thing in that chain it has -- and the whole design is about not
letting that read as a sequence:

  * MenuFlow.accept returns a new kind, `video`, rather than folding this into
    `blocked`, because the caller has to announce the skip and a distinct kind is
    what forces it to;
  * the runtime prints the skipped screens by name on every run;
  * flow.json carries `skipped_chain` as DATA, so what is missing lives beside
    the decision instead of inside a GDScript string.

After the movie the port returns to the title. Authored, and it has to be: the
game goes into mission 1 and gameplay is out of scope. The ~4.5 s before the
movie is left EMPTY on purpose -- GP_TITLE does carry a loading screen and 4.5 s
is about the right shape for one, which is exactly why that belongs in BLOCKED.md
and not in flow.json.

`--script`'s 20 s per-step timeout would have killed every movie run at step 1.
Raising the constant would have been wrong the other way: a movie stuck at frame
0 would then hang the job, and a job that waits is worse than one that fails. The
test is now LIVENESS -- while get_stream_position() advances the deadline moves
with it, and a stalled movie still trips the same 20 s.

Found while looking: GP_TITLE's four unnamed builds (entries 0, 1, 12, 15) are
LOADING screens -- every element in all four is pgloading_*, and LOADING is one of
the three names the decoder read out of the title part's state function. NOT
renamed here: which member of each pair is which locale is an inference, and a
name stops being questioned once written. Handed over.

One of them is a second casualty of the rest.t problem, and a worse one:
pgloading_eff00.prm rests OPAQUE BLACK at t=38, so anything drawing that screen
at its declared rest paints a black rectangle over all of it. The title's case
only dimmed a frame.

REFUTATION, attempted and SURVIVED: HANDOFF says "exactly the six screen builds
carry the black .prm quad while the six overlays do not". Counting bundles with a
full-screen black primitive gives 8 and 4 -- build_12/15 carry one too. But
theirs runs black -> held -> clear where the transition quad runs black -> clear
-> black, so read strictly as "the quad whose group is the transition" the claim
holds. Recorded anyway: there are two kinds, and the naive census over-counts.

Gate: NEW GAME -> S00A plays 93.75 s against a declared 93.9 -> title, with
98.453 s recorded off the Master bus. What that does NOT show is that S00A's own
audio is in the mix -- bed and movie were not separated in this run, and the
write-up says so.

1f1fe647f2 port: end the boot when BOTH builds have arrived, not when the plate lands
Moving the plate onto the shared clock moved the boot's exit with it: the run
quit at the overlay's settle (t=238) while build 4's own fade-in from black runs
to t=261. pteff00 is still ~7 % opaque there, so the capture came out visibly
darker than the previous one -- with nothing failing, no warning, and no line in
the log to say why. Caught only because there was an earlier capture beside it.

The boot now ends at max(view.settle_time(), overlay.settle_time()) and prints
the unit it is waiting for.

c225852fb3 port: the ring spins, the plate needs no constant, and rest.t was never the settle
Two milestones' known-wrong bits, both now answered by the RE agent, both taken.

P5 -- the focus ring. It was drawn at 0 with a comment saying so. The period is
now measured (continuous spin, eight evenly spaced autocorrelation peaks over
nine revolutions, no angle estimated anywhere) and it needs NO authored
constant: the period is the element's own declared t=120, and what the
measurement adds is only that the turn repeats rather than stopping -- which
"groups hold" could not decide, because 0 and 360 are the same pose.

`spin_period_units` is structural and narrow on purpose: two keyframes,
differing in nothing but rotation_deg, by a full 360, first timed and second
untimed. 16 of 212 elements in this export match and all 16 are focus rings,
zero false positives. That check is the point -- the measurement was taken on
ONE button of ONE screen, and a rule that caught anything else would be
extrapolating it to elements nobody watched.

Verified on the port's own render with the RE agent's own control: bit-identical
one period apart across the whole frame, 3.6/255 inside the ring's box at
quarter-period steps, and box luminance conserved to 0.027 % over eight phases
-- which is the observable they used to separate rotation from a pulse. Not
claimed: direction (no signed angle was ever measured) and phase across a focus
change (their run held focus throughout).

P3 -- the plate. Last iteration I refuted their authoring instruction and
shipped it anyway rather than pick between two of their numbers. The refutation
held and the answer came back better than either option I offered: AUTHOR
NOTHING. Both builds run on one clock started together and the plate arrives at
its own declared t=238. The 2.13 s constant is deleted.

The premise that failed was mine: rest.t IS NOT WHEN A SCREEN SETTLES. It is the
last hold keyframe before the exit. ptlogo1 stops MOVING at t=42 and then creeps
5 px and 31 alpha steps to t=251. Reading rest.t put build 4's arrival at 4.350 s
instead of 1.967 s, and the "2.51 s, which is not a landmark of anything" I sent
them is that error wearing a decimal point. 238 - 118 = 120 units = 2.000 s
against a measured 2.135 s at 28.1 fps presentation. Checked against my own
export before touching anything.

`ScreenView.settle_time()` still uses rest.t, and so the boot sequencer paces
every screen off the wrong landmark. NOT changed here: "visible arrival" is a
heuristic and getting it wrong re-paces everything. Filed, and asked for a timed
boot instead now that their oracle is live.

REFUTATION: two of their pages measure the same declared 120 units of wall clock
during a static hold and disagree by 2 % -- plate 2.135 s (28.10 fps implied),
ring 2.177 s (27.56 fps). That is seven times the plate page's own 6 ms
run-to-run agreement, and it lands on the argument that page uses to justify
itself: "the build-in is where frames are dropped; the static hold is not". Also
the ring page's band, 27.6-28.8 fps, does not contain its own measurement -- the
mean needs 27.56 and four of seven spacings are outside. Filed, not worked
around: my port uses the declared 120 units either way.

9b30fb5933 port: P3 -- the boot title gets its PRESS (A) plate, and two of the RE agent's numbers do not agree
ScreenView now draws two builds at once, which it never had to before. It is a
second ScreenView in the same SubViewport rather than a subordinate screen
inside one: each build has its own timeline, its own textures and its own hold,
which is the entire content of the finding, and Node2D siblings already paint in
tree order. `paint_order` still means what it meant -- an ordering WITHIN a
build.

The delay is authored in flow.json on the BOOT STEP, not on the `title` screen.
What was measured is the boot title; whether the plate is there when the title
is reached again -- (B) from the menu, or after the attract movie -- is not, and
hanging it on the screen would quietly claim that it is.

REFUTATION, and it is the substance of this commit: the RE agent's authoring
instruction does not reproduce the RE agent's own measurement, and the gap is
3.97 s. The instruction is "when build 4 has settled, wait 2.13 s, composite
build 2". But build 2 has a group and this port plays groups -- ptbtn00 is alpha
0x00 at t=214, still 0x00 at t=236 while it slides 10 px up, and 0xff only at
t=238, which is 3.967 s at 60 units/s. So the plate is first VISIBLE at
settle+6.10 s, while what was measured -- the glyph counter leaving 154 -- is
visibility at settle+2.13 s. Both groups starting together puts it 0.38 s BEFORE
settle; build 2 starting at settle puts it at settle+3.97 s; landing on the
measurement needs build 2's group to start 2.51 s after build 4's, which is not
a landmark of anything.

The measurement is untouched -- it is an observation of the running game and I
have no standing to doubt it. What is refuted is the step that turns it into an
authoring rule. So the port ships the instruction, prints the discrepancy on
every boot, and files the row. Same call as the BGM sub-waves: a port that
quietly picks the number that looks right destroys the evidence, because a
corrected boot looks exactly like a correct one.

Also refuted, and it was mine: BLOCKED.md has said since P2 that "no element's
alpha reverses direction anywhere in this export, so nothing pulses". ptbtn00
reverses -- 0x00 -> 0xff -> 0x00 -- and it was in the export the whole time. The
claim had been checked against the screens P2 happened to be animating. The port
still draws no pulse, because no reading of this group yields the measured
2.24 s: the whole group is 4.47 s and from its first keyframe 0.90 s.

Gate: `--boot --capture=` writes one frame of the composited end state, instead
of the 600-PNG filmstrip that was previously the only boot artifact.
`--screen=title --overlay=press_start` raises the same composite in two seconds
for anyone who does not want to sit through 137 s of Theora.

d6252481e1 port: P6 -- the menu has sound, and the BGM I "chose" was decoded all along
The three Static.slb cues and the menu bed now export to Ogg Vorbis and play.
`sylpheed_formats::media` does the assembly; nothing in port/ has heard of XMA.

Three things this milestone got wrong before it got right, all recorded in
docs/port/DECISIONS.md because the corrections are the useful part:

1. The cue offsets were a Rust `const` in the exporter. They are MEASURED, not
   decoded -- a measured value compiled into the exporter is a measurement
   wearing the costume of a decoded field, and nobody deletes it because nobody
   can see it. They are authored/audio.json now.

2. I picked BGM_001 and wrote a careful `why` calling the choice arbitrary. The
   menu's music is BGM_103, and it is in HANDOFF at 0fd8e69 -- the exact commit
   BLOCKED.md says that row was reconciled against. Not stale: wrong when
   written. I had summarised a negative without its reach, so "the TABLES cannot
   say which BGM a screen plays" became "it is not on the disc". One word of
   scope was the whole answer, and the export failed only because BGM_001
   without its .slb extension hashes to nothing. That is luck, not design.

3. The comment above the BGM sum argued for unity gain "because halving is a mix
   decision nobody made". It clipped at +1.8 dBFS. 1/n is the smallest constant
   that provably cannot clip -- the same reasoning video.rs already carried for
   its 5.1 downmix, in this repository, unread.

Unsettled and shipped as such: media::sound_bank_riffs returns THREE sub-waves
for BGM_103.slb where HANDOFF Q10's census says exactly two (the third is the
leading headerless region slb.rs emits for the voice path). The exporter sums all
three and writes a manifest warning, because which bytes belong together is the
decoders' question, not this exporter's -- and dropping one would destroy the
evidence, since a corrected export looks exactly like a correct one. Raised with
the Decoder; row in BLOCKED.md.

The gate is a null control, not a peak reading. A master-bus WAV that is
non-silent proves nothing -- the bed alone would look identical. So the same
scripted walk was run with <- in place of <v>, which fires no cue (Q5, measured),
and the difference is one 0.55 s burst at t=1.10 s and silence everywhere else.
The first attempt at that control returned bit-identical zero and I nearly filed
it as "cues never reach the bus": both runs ended at 1.115 s and the first press
lands at 1.17 s. A null result from an instrument that was not running is not a
null result.

Refutation attempt: HANDOFF Q8's three cue durations. They looked attackable --
0.133/0.172/0.169 s per packet, no shared rate -- but an XMA1 packet carries a
variable number of 512-sample frames, and the three come to 50.0/32.3/95.3
frames. Measured off the decoded Ogg: 0.533, 0.344, 1.016 s, every published
digit. SURVIVES, with its reach stated -- it confirms the assembly path and my
transcription, not the event bindings, which only an oracle can retake.

76979c799c port: P5 end to end -- and the port's title never says PRESS (A)
The P5 gate walk starts on a screen. This runs the whole objective instead, and
it is the only thing that would have found what it found:

  xvfb-run -a godot --path port -- --boot --play \
    --script=accept,down,down,down,down,accept,cancel,cancel --shots=/tmp/e2e

publisher wordmark -> developer logos -> ADV (151.9 s) -> title -> (A) -> main
menu -> navigate -> (A) -> EXTRAS -> (B) with focus restored to ptbtn05 -> (B)
-> title. 166.76 s, exit 0, nine frames. Shared as 1788003274-e68367e787d5.

THE PORT'S TITLE DOES NOT TELL THE PLAYER TO PRESS (A). The boot's last step is
`title` = GP_TITLE build 4, and build 4 has NO `PRESS (A) BUTTON` plate. P5 has
just made (A) the only way off that screen.

Not a guess about the art -- both states are captured off the running game and
differ by exactly that plate (live-title-build4-no-plate.png vs
live-title-press-a.png), and the plate is ALREADY EXPORTED as `press_start`,
build 2, sitting in export/screens/title/ unused by anything.

RECORDED, NOT FIXED, and the distinction is the point. This is P3's gate that
P5 exposed, and fixing it needs two things the port does not have:

  * WHICH state an idle post-boot title shows -- build 4 alone, build 4 with the
    plate over it, or build 4 THEN the plate after a delay -- is BEHAVIOURAL.
    The game demonstrably has both states and nothing says which follows the
    intro. The port has no oracle for a sequence; that is the Decoder's.
  * showing it means DRAWING TWO BUILDS AT ONCE, which this port has never done
    -- every mode loads exactly one screen. That is a change to ScreenView, not
    a line in flow.json, and it is not being smuggled in under a navigation
    milestone on the strength of "it looks more right".

Filed in BLOCKED.md. P5's gate is (A) into a submenu and (B) back; both work.

Two smaller things the same run found, both fixed:

  * the boot step's `why` still said "nothing takes the title's place until P5
    gives it somewhere to go". P5 has. Now says what is true: `--boot` STOPS on
    the title (a boot that ends by fading to black looks like a crash) and
    `--play` HANDS THE HELD TITLE OVER -- the stop is not a bug and the handover
    is not another boot step.
  * an empty focus printed as a line that trailed off, reading like a value had
    gone missing rather than like there is none. The title is a screen with no
    `buttons` that still takes (A), so it now prints
    "(none -- this screen has no focusable item)".

Also confirmed: entering a submenu directly (`--menu=extras`) and pressing (B)
enters the parent at its AUTHORED initial focus, not a restored one. There is no
history to restore and MenuFlow.cancel only claims a restored focus when the
stack agrees about where it is going.

Sylpheed port agent
1defbe0a32 port: P5 -- the menus navigate, and the focus ring is drawn wrong on purpose
P5's gate is "a human clicks through it". The artifact is a scripted walk that
proves the wiring rather than the intent -- up (wraps 01->05), five down, (A)
into EXTRAS, down, (B) back, landing on the main menu with focus RESTORED to
EXTRAS, ten PNGs one per settled step:

  xvfb-run -a godot --path port -- --menu \
    --script=up,down,down,down,down,down,accept,down,cancel --shots=/tmp/p5

--script posts InputEventAction through Input.parse_input_event so the presses
arrive at _unhandled_input exactly as a d-pad's would. Calling MenuFlow directly
would have been shorter and would have proved nothing: the wiring between a
press and the cursor is the part most likely to be broken, and a direct call is
exactly the part that skips it.

Derived vs authored, which P5 is the easiest place to blur:

  * DERIVED -- the ORDER of the items, from each screen file's `buttons`, which
    the exporter already fills from button-role elements sorted by resting Y.
  * AUTHORED -- destinations, initial focus, what (B) does, and left/right being
    a no-op. All measured off the running game (HANDOFF Q4/Q5) or chosen, none
    on the disc, all in authored/flow.json with a why.

Four of five main-menu destinations are `goto: null` with a `blocked` note. That
is a MILESTONE BOUNDARY, not an unknown -- DIFFICULTY, the save list, the lesson
list and OPTIONS were all measured and live in archives this export does not
carry. `blocked` and `none` are kept apart so nobody later "discovers" the gap.

--headless CANNOT DRAW, and the port hung instead of saying so.

Measured, not assumed: under --headless Godot's dummy renderer never emits
RenderingServer.frame_post_draw, so every capture path awaited it forever --
--capture since P1, --film since P3, --shots as of now. With stdout block-
buffered the observable behaviour was SILENCE, FOREVER, which in a loop reads as
a job still working. Isolated by `--quit` (prints, exits 0) vs `--capture` (zero
bytes, killed at 40 s). Now those three flags refuse at STARTUP naming the
xvfb-run line that works, and --script no longer waits for a frame it is not
going to photograph -- so headless walks the menus in 4.5 s as a cheap
regression check needing no X server.

REFUTATION ATTEMPT, against the Decoder's 76653ca point 2 ("the oracle confirms
the game renders the ring's rotation"). Aimed there because PROTOCOL says to aim
at a claim the port is about to build on that rests on an estimator whose own
control the Decoder reported as +/-19.8 deg. IT SURVIVES, more strongly than
claimed.

Both captures draw the SAME sprite (ptbtneff01) 240 px apart, so "is it drawn
rotated" becomes "are these two crops one image at a different angle" -- no crop
offset needed and no reference to our own renderer. 360-bin angular luminance
profile over the annulus, circularly cross-correlated. Two controls first: known
rotations 0/30/90/150/210/270/330 recovered with 0 deg error, and a ring-free
patch of the same capture peaks at 0.369, so the estimator does not manufacture
matches. Then: A vs B 134 deg (corr 0.968), sprite vs A 76 deg, sprite vs B
210 deg -- and 210-76 = 134, which nothing in the method forced.

So 0 deg is NOT A POSE THE GAME SHOWS, and screen_view.gd draws the ring at
0 deg. That is now stated in the code as known-wrong rather than suspected. The
port did NOT start spinning it: the period has two unknowns and both are the
Decoder's -- the second keyframe is untimed, and "groups hold" predicts a stop
at 360 = 0 which contradicts both captures. Two frames of one focused button a
known time apart settle it. Filed in BLOCKED.md and asked over the channel.

BLOCKED.md's staleness check was half a check. It tested whether that page is
stale relative to HANDOFF; it cannot see the other direction, and the other
direction is what happened -- 76653ca lands 27 minutes AFTER HANDOFF was last
written and answers a question HANDOFF still lists as open. Added the missing
half: `git log --oneline 0fd8e69..HEAD -- docs/re/`.

Also recorded, since the two were nearly confused: the ring's annulus centroid
lands within ~0.4 px of its design position under a ZERO crop offset, which
corroborates ORACLE-CAPTURES' "1279x675, top-left aligned" on a feature nobody
chose for the purpose. The earlier "text bands at design y + 23" is an offset
WITHIN the button sprite, not a crop offset.

3e280d63de port: P5 groundwork -- the focus record, measured and checked against a capture
P5 is the lowest unfinished milestone. This does not implement navigation; it
settles how a focused button is drawn, because three claims sat under that and
none had been checked from this side.

Refutation attempts, all three failed -- recorded either way, per PROTOCOL:

  * HANDOFF ask 3's '(7,7)' focus offset SURVIVES, and more strongly than
    stated: over a 15x14 scan of the whole offset space it is a UNIQUE
    ISOLATED cell at 100% coverage on all five buttons, with (6,6) and (7,6)
    both below 90%. The centre and pivot alignments reproduce the 78-84%
    band the RE agent called misleading.
  * ORACLE-CAPTURES' 'a crop, not a scale' SURVIVES. Its own evidence -- a
    +/-6 px cross-correlation -- cannot tell a crop from a 0.9375 scale, so
    it was re-tested with a scale-sensitive one: button text bands land at
    design y + 23 for all three unoccluded buttons, an exactly 1:1 vertical
    mapping. (The prose understates 45 missing rows as 'the missing row'.)
  * My own suspicion that the declared geometry disagreed with the capture
    by 6 px was MY ARITHMETIC ERROR, written up rather than quietly dropped:
    I took the top-left as pos - pivot. pos IS the top-left; the pivot is the
    anchor scale grows about and cancels at 100%, exactly the 'can be got
    wrong invisibly' that screen_view.gd:120 warns about.

What is actually true, and what P5 does with it:

  * The exporter ALREADY emits the focus record's second element, the 42x46
    ring ptbtneff01, for all five buttons. That gap is in the renderer, not
    the exporter -- nothing to change in crates/sylpheed-export.
  * Base minus focus is (7,7) directly from the declared positions, so P5
    draws each focus element at its own pos and authors no constant.
  * ptbtn04 is 1 px off the 80 px grid ON THE DISC (base rows 162 242 322
    401 482; focus rows a clean 155 235 315 395 475). So its base->focus
    delta is (7,6) while its art aligns at (7,7). Do NOT derive focus
    placement from the base by a constant: it would be wrong on exactly one
    button and right on the other four.

Verified against captures rather than our other renderer: diffing
live-main-menu against live-main-menu-options-focused isolates one cluster at
x 506..702, y 398..445, and ptbtn04's focus record under pos-as-top-left spans
x 500..706, y 395..451. Under pos - pivot it predicts x 433..604, y 367..422,
which matches nothing in the capture and no other button either.

Also records an instrument that FAILED ITS CONTROL and was discarded: a masked
NCC template matcher returned NCC 0.096-0.206 with three of five results pinned
to the search boundary when asked to re-find the base sprites at their known
positions. None of its output is used. Filed so this is not rebuilt.

d090c9c75c port: reconcile BLOCKED.md against the in-repo HANDOFF at 0fd8e69
The page cited '/reborn HEAD 9501879' and that address no longer resolves,
for two reasons it now records:

  * the repositories were merged into one monorepo (9fbb352), so HANDOFF.md
    is docs/port/HANDOFF.md **here** and its provenance is a sha in this
    history -- a sha from the old repo cannot be looked up at all;
  * /reborn is still mounted but is now an EMPTY DIRECTORY, so a test for
    the mount passes and every read under it fails with ENOENT.

Staleness is now checkable in one command instead of by trusting a date:
`git log -1 --format=%h -- docs/port/HANDOFF.md`.

Three rows were listed as blocking that HANDOFF has since answered:

  * Q4 -- and the old row was WRONG, not merely stale. It said A on
    NEW GAME 'hangs the emulator'. Q4 now reads measured for all five
    buttons, NEW GAME -> DIFFICULTY -> SELECT DATA, 'not a hang'. This is
    what unblocks P5.
  * Q9 -- one A skips a movie, measured. P4 had already taken it; the row
    survived only because nobody deleted it.
  * Q6 -- answered as a negative with a stated reach (the driver is code,
    not data, four search spaces closed), which is not the same as unsettled.

The five asks are recorded with what came back: four answered at 0fd8e69,
and only ask 4 (rotation) still open -- with the human, not the RE agent.

Adds one question the port raised and did not guess: whether the focus ring
spins while focused. Its group ends 0 -> 360 deg on the untimed keyframe, and
'groups hold' cannot decide it, because 0 and 360 are the same pose.

1c80e54914 port: gitignore the export tree, which MISSION already said was ignored
`export/` is what `crates/sylpheed-export` writes and what
`ExportTree.locate()` reads. It was **not** gitignored. `data/base/` was --
the name MODDING.md gives the same tree, and a directory nothing writes.

So the live output directory was tracked while MISSION §4 states, as the
hardest rule in this project, that it 'is generated from the user's own disc
and is gitignored'. A `git add -A` in a container that had run the exporter
would have committed the disc: 16 screens of sprite PNGs and two transcoded
.ogv reels.

Nothing was committed -- this repository's history is clean, and a fresh
container reproduces the hazard rather than inheriting it, because the export
tree is regenerated and never cloned.

Both names are now ignored, so renaming the tree to match MODDING.md later
cannot silently re-open this.

Prompted by the Decoder's point that a decorative second support is worse than none, since a conclusion with two supports reads as better evidenced than one and apparent redundancy is itself the misinformation. Read literally, 'disc census' and 'runtime' could be ONE comparison -- declared wave sizes matched byte-for-byte against the probe -- which would make three legs two. It is a real third leg only if the census EXCLUDES alternatives: if another bank carried the same two sizes, the byte match would not distinguish BGM_103. Measured with this port's own reader (`crates/sylpheed-export/examples/bgm_size_census.rs`): of 32 readable BGM_* banks on the disc, EXACTLY ONE carries waves of that size. The census therefore excludes, the static-code leg names the cue independently, and the three legs stand. ✅ AND THE EXCLUSION IS TIGHTER THAN I STATED. The Decoder attempted to refute it from their own census tool rather than this port's reader: of 32 census rows, exactly one bank carries EITHER of those wave sizes -- not merely both together, which is what I measured. A collision would therefore need to reproduce a single size, not a pair, and none does.",

The bed loops; the loop is a RUNTIME field -- `loop_start`/`loop_end` in the XMA decoder context, set by `XMASetLoopData` and logged by Xenia -- and the cycle was watched directly: three wraps, both contexts wrapping at the same instant every time, mean 61.81 s against the 61.93 s authored in `loop_end_s`, 0.2 % apart from instruments sharing nothing. The export is TRIMMED to that window, because Godot loops a whole file and a loop region therefore has to BE the file. ⚠️ The window's START is not measured and is authored as 0, which is known to be wrong -- see `loop_start_why`. 🔴 EVERY SENTENCE THAT PRECEDED THIS ONE WAS REFUTED, and the previous text survived in the manifest for two days after the corrections were written. It said the loop would be `AUDIBLY WRONG AT THE SEAM [refuted]`, that `no loop-point field has been identified [refuted] anywhere`, and that trimming `would INVENT a loop point`. All three are false: the field exists, the 3.4 s of near-silence was the PORT'S loop and not the game's, and the trim is now what the measurement says. The corrections went into `loop_end_why` and `loop_start_why`; this field is the one the exporter concatenates into `manifest.json`, so the export went on telling readers the refuted story.

Concatenating them plays the piece twice, the second time as a bass-less stem; that was the previous reading and it is refuted. Emitting two files would be wrong for a second reason: MODDING rule 1 is one logical asset, one file, and handing a modder two stems to line up by hand is the reassembly the exporter exists to have already done. WHAT IS SUMMED IS SETTLED; WHAT WAVE 1 IS, IS NOT -- HANDOFF calls it quieter, far more L/R-decorrelated and almost bass-free, so it reads as a surround-rear pair OR a second intensity layer, and `ChannelMask` is 0x0002 on both so the file will not say.

The oracle measured 2.138 s and 2.132 s. The gap is presentation rate: 120 units in 2.135 s is 56.2 units/s, i.e. the emulator presenting at 28.1 fps against a nominal 30, and the corpus had independently measured the idle title at 28.5 fps before these runs. 📌 SOURCE, added 2026-09-01: the pulse period and its phase behaviour are in docs/re/structures/plate-pulse-measured.md and docs/re/structures/plate-pulse-phase-lock.md, with the raw series in docs/re/data/plate-pulse-timeseries.txt. ✅ AUDITED 2026-09-01: the corpus's 28.5 fps is a genuinely independent leg -- a different quantity (idle-title presentation rate), measured BEFORE these runs, so it could have come out disagreeing.

Looping that record is a candidate the port has NOT taken: its group is 105 timed units plus an AUTHORED 24-unit exit ramp, and hitting the measured 2.24 s mean requires composing that authored constant with a loop assumption, which is tuning rather than measuring.

Identified by rendering all five focus states and taking the minimum difference -- 531 differing pixels against 6080-7094 for the others, an 11.5x margin -- with the method controlled on live-main-menu-options-focused.png, whose answer is in its filename and which it picks by 4.7x. That means the port's choice matches the state of one committed frame. It does NOT make focus stable: Q5's four boots gave TUTORIAL, TUTORIAL, NEW GAME, NEW GAME, and this identifies one frame rather than a rule. Delete this entry the day something says what SELECTS it. TIGHTENED 2026-08-29: Q5 now has SIX boots, and the shape is sharper than 'unstable' -- TUTORIAL x3, NEW GAME x3, and NO OTHER ITEM EVER OBSERVED. So it is not uniform over five buttons; whatever selects it has to explain a two-way split. That does not change this choice (NEW GAME remains one of exactly two observed states, and it is the state of the committed capture) but it does change what would REFUTE it: a boot opening on LOAD GAME, OPTIONS or EXTRAS would break the two-way shape, and a rule that predicts the split would delete this entry outright.",

"fields shifted one word, so every record was being credited with the PREVIOUS",

"",
"❔ STILL UNBOUND, and it is what would make this airtight: nothing connects",

//! Run the Decoder's own falsifier for "a nested record's `+0x08` is its loop
//! length" against the bundles THIS PORT SHIPS, before shipping 120 for 105.
//!
//! HANDOFF (`27938aa`, delivered at `07e93ce`) says the plate's glow cycles over
//! **120** units while its keyframes end at 105, and instructs the port to stop
//! shipping 105. The port's `ScreenView` derives a looping record's period from
//! the element's largest keyframe time, so it does ship 105 — and the field that
//! would fix it is decoded in an *example* and a *test* on the Decoder's branch
//! and **exposed in `sylpheed_formats`' public API on no ref at all**.
//!
//! ✅ **Since then the crate exposes it** — `ui_layout::loop_length_units`, taken
//! at `formats-pin-2026-08-30b` — and `screen.rs` has deleted its local copy.
//!
//! 🔴 **This file deliberately did NOT follow it.** The read below is still the
//! raw four bytes, because the moment a control calls the API it is meant to
//! check, it stops being a control and becomes the API tested against itself. It
//! is the independent reading that makes the falsifier mean anything.
//!
//! So this re-runs both of their controls:
//!
//! * **the falsifier** — `+0x08 < max keyframe time` must never occur; an
//! animation cannot restart before its own last pose;
//! * **non-triviality** — if every record had `+0x08 == max t` the field would
//! carry nothing and the name would be a relabelling of the keyframes.
//!
//! and adds the one they could not run: the same two, restricted to the records
//! **this port actually animates**. A disc-wide 0.00 % violation rate says
//! nothing about my six screens if all six sit in the exceptional tail.

# Your mods go here
A mod **replaces a file by shadowing its path**. There is no manifest, no
registration and no load order: if a file exists here at the same relative path
it has in the export tree, the game reads yours instead.
```
export/sprites/title/main_menu/ptbtn01.png <- what the exporter wrote
data/mods/sprites/title/main_menu/ptbtn01.png <- what the game will use
```
That works for **every** asset kind the port reads — a screen's JSON, a sprite
PNG, a sound cue, the music bed, a movie — because every read goes through one
resolver (`port/scripts/export_tree.gd`, `ExportTree.resolve`).
Nothing under `export/` is ever touched, so **re-exporting from your disc is
always safe**, and *"did I break it?"* is answered by moving your file out of
this directory.
Point the game somewhere else with `SYLPHEED_MODS=/path/to/tree`.
## The game tells you what you changed
Every file a mod replaces is printed the first time it is read:
```
mod: sprites/title/main_menu/ptbtn01.png <- /work/data/mods/sprites/title/main_menu/ptbtn01.png
```
A modded run that looked identical to an unmodded one in the log would leave you
with exactly one debugging tool — delete the mod and try again.
## Try it in ten seconds
Replace the `NEW GAME` label with a magenta block. The size is the original's,
`203x43`, and nothing here is derived from the disc:
```bash
mkdir -p data/mods/sprites/title/main_menu
ffmpeg -f lavfi -i "color=c=0xff00c8:s=203x43" -frames:v 1 -pix_fmt rgba \
data/mods/sprites/title/main_menu/ptbtn01.png
godot --path port -- --menu
```
Delete the file to put it back.
## Nothing in here is committed
`.gitignore` excludes everything in this directory except this README. That is
deliberate: a mod is usually an *edited game asset*, and this repository never
holds game assets — not in `export/`, and not here either.
## One tree, not a stack
Several mods layering over each other would need a load order, and a load order
needs a rule nobody has asked for yet. Today there is one override tree. If you
want more, say so rather than assuming the port has an answer.

# Agreed retro — Port and Decoder, 2026-08-31
Two self-reviews, one round of mutual attack, and the result both agents accept.
* Decoder's own review: `docs/agents/RETRO-2026-08-31.md` on `auto/frame-blend-draw-path`.
* Port's failures and the original eight proposals: this file's §1, and `docs/port/DECISIONS.md`.
⚠️ **Nothing here is applied to `PROTOCOL.md`.** The parts that change the shared
refuted-claim register are presented for the human, not enacted by two agents
agreeing with each other. Both agents remain paused.
## 1. The single most expensive thing we did
**We let claims that rest on our own renderer sit in the register as settled
refutations.**
`REFUTED.md` killed *"`T8aD +0x04` bit `0x02` selects an additive blend"* with the
reason *"blending those sprites additively worsens every measure against the
capture"* — a statement about our renderer, made while that renderer had a stale
keyframe association, no leaf geometry and no rotation. The field is real. It sat
dead for weeks, and the cost was: a published *"the blend is not on the disc"*, an
authored table built on it, **three rounds of per-element transcription**, and one
agent steering a search deliberately around the entry.
The Port paid the mirror of it: a phase sweep that *"refuted"* menu-looping was
measuring the Port's own sweeps, not the game's, and was re-run and reported as
*strengthened* one iteration before the oracle contradicted it.
📌 **Neither of us was careless. The rule was in `PROTOCOL.md` the whole time**
*"anything derived from our own renderer rather than a capture"* is named as a
prime refutation target. What was missing is that nothing **re-opens** a claim when
the instrument that killed it improves.
## 2. The gap underneath our controls
`PROTOCOL.md` already requires running an instrument through a control. **We both
did, and it did not help**, because:
> **Our controls verified capability, not configuration.**
* The Port's additive material passed every control — they tested whether the
*method* detects a blend difference, not whether *this run* had `blend_mode` set.
It was left at Godot's default, `MIX`. The change predicted a large move and
delivered **0.03**, and would have been publishable as a careful negative.
* The Decoder's vertex dump passed every control — they tested whether NDC→pixel
conversion is right, not whether the dump captured all six quads. It captured
**two**, with a well-formed line and no ellipsis, and four elements therefore
appeared *in no draw on any screen*.
## 3. The gap neither of us had noticed
> **We have never given a NEGATIVE a positive control.**
Every *"undecodable, with reach"* page lists **where we looked**. Not one shows
that the search method **can find a property that is there**. *"Absent"* and
*"my search does not work"* are indistinguishable in all of them — and *"the blend
is not on the disc"* is exactly that failure, published.
## 4. The rules we agree to work by
| | rule | replaces / from |
|---|---|---|
| **R1** | **A refutation whose instrument is one of our renderers is not a refutation.** It is *"our renderer disagrees"* — 🟡, not ❌. Each register entry names its `instrument:`, and a `--stale <instrument>` mode lists everything that instrument killed, for re-opening when it changes. | Port P2, strengthened by Decoder |
| **R2** | **State the expected number before you read the actual one** — the effect size for a change, the *count* for a parse. *"This draw declares 24 indices, so I expect 6 quads."* | Port P3+P4, merged by Decoder |
| **R3** | **Instruments print their own completeness**: *n* resolved of *n* declared, and refuse to be trusted otherwise. | Port P4 |
| **R4** | **A negative carries a positive control.** Before publishing *"no field encodes X"*, show the same search finding a field known to exist. | Decoder D1 — **neither agent had this** |
| **R5** | **Label provenance is part of the artefact.** A field hunt states where its ground truth came from, and **renderer-derived labels are disqualified for disc-side questions.** | replaces Port P1, which had no teeth — the question *was* asked and answered wrongly |

## 5. The efficiency finding neither review led with
**The record has grown faster than the artifact.** `DECISIONS.md` is past 13 000
lines. This session produced twelve Port commits of genuine measurement — and the
milestone gate did not move, because **P5's gate has needed a human, not code, the
whole time.** Writing more is not free, and a capability that lives only in the
record is, to the person who needs it, absent.
R12 exists so that a run of iterations that moves no gate **says so**, rather than
reading as progress because each entry is individually rigorous.
## 6. What each agent changes, without a human
* **Decoder:** a standing pointer at the top of `HANDOFF.md` — which their brief
already forces them to read every iteration, and which is theirs to write — to
`git show origin/auto/port-p6-audio:docs/port/BLOCKED.md`. **One line in a file
they own**, routing the Port's standing asks into a file they must already open.
This closes a gap `BLOCKED.md` records as having cost three sessions.
* **Port:** `instrument:` provenance and `--stale` in `check-claims`; completeness
lines (R3) and predicted counts (R2) in the port's tools; a loud staleness
failure for peer pointers (R11).
## 7. What needs the human
1.**The register re-classification (R1) — DONE 2026-09-01, by the human**, on
`docs/re/REFUTED.md` at the Decoder's tip. All **222** entries now carry an
`⟨instrument⟩`; the file opens with a reading guide naming which instruments
are ours; R1 is now standing text in `PROTOCOL.md`; and
`tools/stale-instrument` is the `--stale` query — run it whenever you improve
a renderer, a reader or the harness, and it lists what that instrument killed.
**Ten entries moved ❌ → 🟡**, each naming what would settle it: eight
`render-vs-capture`, one `our-reader`, one `harness`.
Three things the pass turned up that neither self-review had:
* **The `rest()` question is open, and had been reading as settled in both
directions.** *"rest = last keyframe"* was refuted by the sibling argument;
that refutation was then refuted by correlating our render against
captures. Both legs run through our renderer, so under R1 neither survives
— and which one you believed depended on which entry you found first.
🔴 **This one is load-bearing for the port**: `rest()` decides the pose
every plateau-less element is drawn at.
* **A withdrawal never reached its sibling.** *"2 391 frames, max glyph 0"*
was withdrawn because a long-lived `x11grab` stream degrades and then
repeats a stale frame. The 1 674-sample negative three lines above it —
same probe, same instrument, comparable duration — was left standing as a
*reinstated measurement*. §1's lesson, inside the register itself.
* **83 of 222 entries — 37 % — record no instrument at all.** Not disputed,
not safe: **unauditable**. `stale-instrument unrecorded` is the backfill
queue, and it is larger than every other group combined.
2. **P5's gate** — a person clicking through the port. Unchanged, and it is the
only thing standing between the milestone and done.

## 5. A multichannel capture must pass a provenance check BEFORE it is analysed
`tools/port/check-capture FILE.wav` — run it first, every time.
⚠️ **This section exists because a capture of the game's own 6-channel output was
analysed at length and the file was corrupt.** It got three controls, a
drift test and a written-up negative, and every one of those was sound; none of
them could see that channels were missing, because the corruption was upstream of
everything they tested.
**PulseAudio was remapping between two mismatched channel maps, and a 6-channel
remap silently drops and duplicates.** The Decoder proved it with a control that
needs no emulator and no disc — six channels each carrying a different tone,
through the same sink and the same `parec` invocation
(`docs/re/audio-capture-channel-map-trap.md`):
| ch | played | recorded |
|---|---|---|
| 0 | 400 | 400 |
| 1 | 800 | **3200** |
| 2 | 200 | 200 |
| 3 | 1600 | **800** |
| 4 | 3200 | **800** |
| 5 | 6400 | **200** |
**Two source channels were gone entirely** and two were duplicates. Setting the
sink's `channel_map` to the guest's own (`FL,FR,FC,LFE,RL,RR`) and passing the
same map to `parec` returns all six.
### The signature is an exact duplicate pair, and only a hash finds it
Duration is right. Channel count is right. `Corked: no`. There is no error
anywhere, and the **per-channel levels look entirely reasonable** — which is the
whole difficulty. In the tool's own known-bad control, all six channels report a
peak of **18.063656 dB, identical to six decimals, while containing three
duplicate pairs.** A level check cannot see this. Hashing each channel can.
Two channels of a real surround mix are never byte-identical over tens of
seconds. On the corrupt game capture the tool reports:
```
ch2 peak -4.466272 ba497de78217c438a3e430c5ef6b951b
ch5 peak -4.466272 ba497de78217c438a3e430c5ef6b951b
🔴 ch2 and ch5 are BYTE-IDENTICAL
```
⚠️ **It is a necessary check, not a sufficient one.** Passing says the file has no
duplicated channels. It says nothing about whether the right thing was recorded —
that is what §1's correlation against a known source is for, and a capture should
survive **both** before anything is concluded from it.
### Two more conditions, learned the same way
* **Start the recorder before the process you are capturing**, so `t = 0`
precedes it and the window certainly contains the moment of interest.
* **Log what was on screen, with timestamps keyed to the recording's own clock.**
A capture that matches nothing is then diagnosable rather than ambiguous; the
corrupt one could not be told apart from "recorded the wrong phase of the boot"
by any amount of analysis at this end.
And the failure this page already warns about, in a second costume:
`run-canary` is silent **twice over**`SDL_AUDIODRIVER=dummy` *and*
`--mute=true`. Fix only the first and Canary attaches a healthy 6-channel stream
at 100 % volume, reports `Corked: no`, and emits a 19 MB WAV of zeroes.
## 7. A capture can be starved — right duration, holes punched through it
`check-capture` tests this too, and it is the second way a recording looks
perfect and carries nothing.
**A monitor sink advances at wall-clock rate and substitutes silence whenever the
producer is late.** An emulator running below real time therefore yields a file
of exactly the right duration, the right channel count, no duplicated channels —
chopped into fragments with holes between them, thousands of times over.
Measured independently on the capture that prompted this (the Decoder's numbers
on the untruncated original in brackets):
| | |
|---|---|
| frames silent on **all six** channels | **35.6 %** [39.3 %] |
| alternating runs | **10 482** [10 595] |
| median burst / gap | **13.5 ms / 3.9 ms** [13.6 / 3.9] |
| period | **17.4 ms → 57 Hz** [≈17.5 ms → 57 Hz] |
⚠️ **This destroys envelope correlation by construction.** What dominates the
envelope of such a file is the dropout schedule, not the content — so §6's method
was working correctly on a file that could not carry the signal, and the negative
it produced said nothing about the game.
### Two thresholds I invented were wrong, and the controls caught both
1. **Counting exact-zero frames.** Real audio crosses zero constantly, so a clean
voice track scored **5 947 "gaps" of median 0.0 ms** and was called starved. A
gap is a **run**, not a sample: only runs of ≥ 1 ms count.
2. **Gap count and median length.** A genuine music-and-effects bed has **454
gaps at a median of 1.4 ms** — quiet 16-bit passages really are zero for
milliseconds — so neither statistic separates it from a starved file.
3. 🔴 **The gap RATE alone.** This one shipped, and the Decoder found it: raising
the client buffer keeps cutting the rate while total silence **bottoms out and
then doubles**, because an over-large buffer starves in a few enormous holes
instead of many small ones. Its `PULSE_LATENCY_MSEC=500` capture scores
**1.3 gaps/s — better than a genuine music bed at 3.3 — while being 50 %
silence**, and a 20/s bar passed it.
**It takes two numbers, because either one alone is blind to the failure next
door** — the same shape as a level table that cannot see a duplicated channel.
Reproduced on a file held here (`bigholes`: a real bed with 350 ms holes punched
into it) so the regime is controlled rather than quoted:
| control | all-channel silence | gaps/s | verdict |
|---|---|---|---|
| real music+SFX bed | 1.1 % | 3.3 | **PASS** |
| voice track, mono, real pauses | 53.2 % | 0.3 | **PASS** |
| bed with 350 ms holes | **46.3 %** | 3.2 | **FAIL** |
| the starved capture | **35.6 %** | 30.9 | **FAIL** |
Rate alone cannot separate rows 2 and 3; silence alone cannot separate rows 1 and
3. **The pair does:** fail when ≥ 10 % of the file is silent on every channel
*and* there is at least 1 gap per second. Real audio is either mostly not silent,
or silent in a few long stretches — not both at once.
### A format it cannot read is refused, not guessed at
Everything in the starvation check assumes 16-bit signed. An ALSA `type file` tee
writes **float32** (`SND_PCM_FORMAT_FLOAT_LE`), and read as s16 that produces a
*plausible-looking* file — the Decoder measured one, and its only tell was
per-channel peaks alternating **exactly**, which is the two halves of each float
landing in alternate channels.
So an unreadable format ends the run at **`PARTIAL`** (exit 2), not `PASS`:
channels were checked, starvation was not, and the tool says which. A checker
that claims a check it skipped is the shape of every failure this file documents.
⚠️ **`WAVE_FORMAT_EXTENSIBLE` (tag `0xFFFE`) is accepted at 16 bits**, and the
first version of the guard was not — it rejected one of this tool's own controls,
a file `ffprobe` correctly calls `pcm_s16le`. **A format guard that refuses a
legitimate capture is the same defect as one that mis-reads an illegitimate one**,
pointing the other way. The check turns on `wBitsPerSample`, which is what
actually decides the sample layout; a float tee is 32-bit and is still caught.
### The control sweep, which is the tool's real specification
**Run it: `tools/port/check-capture-controls`.** 🔴 Until 2026-08-30 this table was prose — the specification existed and nothing executed it, so a regression in `check-capture` or a drifting threshold would have gone unremarked in a tool whose own history is *two invented thresholds that were both wrong and were caught only by controls*. This document states the principle it was breaking: **"a control that does not execute is not a control."**
⚠️ The verdicts below are **compressed**. `check-capture` emits two — one for channel provenance, one for starvation — and the sweep asserts the pair, because the voice control is `PASS` on channels and `UNJUDGED` on starvation *by design* and a single word cannot say that. A starved file **short-circuits** before the channel check, which the sweep records as `n/a` rather than as a failure: *the check did not run* and *the check failed* are different facts.
⚠️ The **starved capture cannot be rebuilt** — that artifact was transient and is gone. The sweep reports it `MISSING` rather than omitting it, and deliberately does not synthesise one from the statistics published above: a control fitted to the answer it must give is not a control either.
| file | verdict |
|---|---|
| real music+SFX bed | `PASS` |
| voice track, mono, 53 % real pauses | `PASS` |
| six distinct tones (PCM and extensible) | `PASS` |
| bed with 350 ms holes punched in | **`FAIL`** |
| the starved capture | **`FAIL`** |
| the same tones as float32 | **`PARTIAL`** |
### ⚠️ The regime this tool cannot judge, and says so
**High silence with very few gaps is what a real voice track looks like (53.2 %
in 0.3 gaps/s) and also what an over-buffered capture looks like.** No statistic
here separates them. The tool prints `UNJUDGED` and tells you to check the file
against a known source rather than passing it silently — because inventing a bar
for a regime with no control in it is how the two bars above came to be wrong.
⚠️ **A control that does not execute is not a control.** An earlier version
returned immediately for a single-channel file, so the mono voice track — one of
the four controls — was never actually run through the check it was meant to
control. Mono now skips only the duplicate test.
### 🟡 The monitor-sink route may be fixable after all — retry before rebuilding
An earlier version of this section said the route *"cannot be fixed by
configuration"*. **Withdrawn.** That inferred from the holes that the guest runs
below real time, without testing the alternative: **the client buffer is simply
tiny.** Xenia asks SDL for 256 samples — **5.33 ms** at 6 ch — against a stock
`daemon.conf` with no fragment tuning.
| client buffer | silence | gaps/s |
|---|---|---|
| Xenia default (~5.3 ms) | 39.3 % | 30.5 |
| `PULSE_LATENCY_MSEC=200` | **15.6 %** | 3.5 |
| `PULSE_LATENCY_MSEC=500` | 50.1 % | 1.3 |
⚠️ Not clean, and not like-for-like — 88 s against 347 s, and the short run covers
the splash logos where silence is real. But **the capture route deserves a retry
at ~200 ms before anyone spends a session on a Canary rebuild.**
### The tap, if configuration is not enough
`parec` reads a monitor that advances at wall-clock rate and substitutes silence,
so **every moment the emulator runs below real time is a hole**, and the timebase
is warped non-uniformly — deleting the silences compresses time unevenly rather
than repairing it. The route that would work is an **internal tap at
`SDLAudioDriver::SubmitFrame`**, which sees every frame the guest produces in
guest order with no wall clock in the loop.
⚠️ That needs a Canary rebuild, and the Decoder has costed it: `build-canary`
targets a source root that does not exist in that container, the warm build tree
is configured against the same missing path, so any change is a full reconfigure
plus a full compile on a box with ~700 MB free and a history of parallel builds
OOM-killing the host. **A whole session for one probe** — the human's call, not
an agent's.
### And a header that never got patched
A streaming writer leaves `data` declaring **0 bytes**. `check-capture` says so
and tells you the duration is unverified — which is not pedantry: the file shared
here was **copied while it was still being written**, and the provenance claim
that came with it was wrong about both its length and what it contained.
## 6. Finding one component inside a mix — and why §1's method cannot
🔴 **This section begins with a retraction.** Two captures of the game's own
output were analysed with sliding envelope cross-correlation and declared not to
contain the intro's audio. **The instrument was never controlled for the actual
task**, and when it finally was, it failed:
> Can it find the movie's bed inside a synthetic mix of that bed plus the three
> voice streams? **r = 0.415** — below the `r > 0.8` bar those negatives were
> judged against.
The first negative happened to be right (the file was independently proved
corrupt by a tone control). **It was right by luck, and the reasoning behind it
was not supported.** A filter that fails its own known-positive is dead, not
tuneable.
### What was wrong: the threshold, not the idea
`r > 0.8` was calibrated on **clean-against-clean** comparisons, where it is
correct — a transcode against its source scores 1.000. A *component inside a
mix* can never score that, because everything else in the mix is uncorrelated
noise from the component's point of view. Judging one task by the other's bar
guarantees a false negative.
**Judge on the LAG and the MARGIN instead.** A real match lands at the *right*
lag with a clear gap to the runner-up; a false one is a plateau. And **band-limit
first**, so the component you are hunting dominates what you measure.
### The calibration, on a known-present and a known-absent pair
Both bands, both directions, envelope at 0.1 s, minimum 60 s overlap:
| hunting | band | against | *r* | lag | **margin** |
|---|---|---|---|---|---|
| the movie bed | 40180 Hz | mix containing it | 0.663 | **0.0 s** ✓ | **+0.111** |
| the movie bed | 40180 Hz | voice-only mix | 0.262 | 31.9 s ✗ | +0.005 |
| voice stream 2 | 3003000 Hz | mix containing it | 0.810 | **0.0 s** ✓ | **+0.248** |
| voice stream 2 | 3003000 Hz | the bed alone | 0.358 | 58.4 s ✗ | +0.005 |
**A 2050× separation in the margin, and the lag is right or absurd.** That is a
decision rule set by controls rather than by tuning until the data agreed —
which is the distinction that matters, and the one the first version of this
method skipped.
⚠️ **Reach.** The known-positive is a *synthetic* mix at equal gains. A real game
mix weights its components differently, so this bounds the method rather than
modelling the real case exactly. It is enough to separate present from absent; it
is not a level measurement.
## What none of this establishes
That it *sounds right*. Every method here shows correspondence to a source, not
that the source is the audio the game plays at that moment, and not that levels
are sane in a mix. A ten-second human listen still answers something no
measurement above does — so when a result rests on one of these, say which one.
## 4. What the exporter checks, so nobody has to remember to
`sylpheed-export` measures **peak level and duration** of every audio file it
writes and records both in `manifest.json`; `sylpheed-export check` refuses a
tree whose peak is ≤ 90 dBFS (silent) or ≥ 0 dBFS (clipping).
Those are content checks in a format validator on purpose. Silence is the failure
this page opens by naming — right duration, right channel count, right size, full
of zeroes — and every structural check passes it. Clipping is the other one, and
the BGM can produce it, because a music bank is two stems summed at unity gain
(HANDOFF Q10).
⚠️ Neither says the audio is the **right** audio. `docs/port/BLOCKED.md` says
which bindings are measured and which are still authored, and no measurement on
this page can move a row there.

modder who dislikes the quality re-runs one line rather than reverse-engineering
what was done to their asset. `why` is where the value came from, in the

running game, or **chosen**. A `why` that does not say which of those it is has
not done its job.

Which bank plays a role is authored and expected to change; a rename on the disc side must not be a change to the Godot project. ⚠️ **`voice` is the exception and keys by MOVIE NAME** (`ADV`, `S00A`), because there is no role to name: the binding of recording to picture came off the disc's own movie manifest, so unlike a music bed nothing about it was chosen |
| `peak_dbfs` | measured off the finished file. **Required.** Silence is the audio failure that looks like success — right duration, right channel count, right size, full of zeroes — and clipping is the other one, which the BGM can produce because it is a sum of two stems at unity gain. `sylpheed-export check` refuses a tree whose peak is ≤ 90 dBFS, and applies a **kind-dependent** upper bound. 🔴 This paragraph used to state a flat *≥ 0 dBFS* and was wrong about the port's own export: `confirm` ships at **+0.18** and the `ADV` voice at **+0.31**, so a consumer implementing a validator from this file would have rejected a valid tree. The rule is: a **`bgm`** is a sum *we* produced, so a peak at or above full scale is our arithmetic and is refused outright; an **`se`** or **`voice`** is a single wave off the disc, mastered near full scale, and a lossy decode of it overshoots by a fraction of a dB — those are allowed to **+1.0 dB**. ⚠️ The +1.0 is a judgement, not a measurement: a few tenths is reconstruction overshoot and a whole dB is not, and if a cue ever trips it the right response is to measure the overshoot distribution, not to loosen the bound |
| `duration_s` | measured off the finished file, so that a claim about a cue's length can be checked against the finding that produced it |
| `name_match` | the game's own cue identifier **guessed by name**. Absent means nobody claimed one — never that the binding is unknown. The binding is the measured part; the name is not |

movie manifest. A consumer plays the two together, **from the same instant**
there is no offset and none is authored. A movie with no `voice` entry is
genuinely unvoiced, which is the honest answer for most `hokyu_*` cutscenes;
nothing is substituted, and the manifest carries a warning naming the movie.
⚠️ The `why` on a `voice` entry names every region chunk the exporter **dropped**
and its measured length. That is not commentary: which chunks of a region are the

# Running the port
**P5's gate is *"a human clicks through it"*, and until now there was no page
telling a human how.** The commands existed — in `boot.gd`'s header comment and
scattered through a twelve-thousand-line `DECISIONS.md`. A capability that lives
only in the record is, to the person who needs it, absent.
Everything below has been run. Where a number is quoted it was measured in this
container, and where the container distorts it that is said rather than left for
the reader to discover.
## 1. Build the asset tree
The Godot project reads `export/`, never the disc.
```bash
cargo run --release -p sylpheed-export -- export --disc /disc --out export
```
Roughly four minutes, most of it transcoding two movies. It **rewrites `export/`
wholesale** — never hand-edit anything in there; hand-written decisions live in
`authored/` beside it, and survive a re-export.
## 2. The P5 walk, from a cold start
```bash
godot --path port -- --boot --play
```
This is the one a human should judge. It boots the way the game does — two
splashes, the `ADV` intro, the title — hands over to the menu on Ⓐ, and then
**stays live and waits for input**.
| you press | what should happen |
|---|---|
| Ⓐ on the title | the main menu opens on **NEW GAME** |
| ⬆ / ⬇ | one item, wrapping at both ends |
| ⬅ / ➡ | **nothing** — measured, and implemented as an explicit no-op |
| Ⓐ on **EXTRAS** | the EXTRAS submenu, opening on **MISSION SELECT** |
| Ⓑ in EXTRAS | back to the main menu, **on the item you left** |
| Ⓑ on the main menu | back to the title |
| Ⓐ on the title again | the menu, **still on the item you left** |
That last row is the one worth checking deliberately: the main menu **remembers
its cursor**, and every submenu **resets** to its own opening item. Both are
measured, and they disagree on purpose.
**The intro is ~157 s.** To skip straight to the menu:
```bash
godot --path port -- --menu=main_menu
```
and to drive it unattended:
```bash
godot --path port -- --menu=main_menu --script=down,down,down,down,accept,cancel
```
🔴 **This example used to say `down,down,accept,cancel`, and it walked the wrong
path.** Two ⬇ from the opening item lands on **`TUTORIAL`**, whose destination this
export does not carry — so the example exercised a *not-carried* message and
returned, never opening a submenu at all. **`EXTRAS` is the fifth item**, so it
takes four. The one submenu P5's gate rests on was the one the runbook's own
command did not reach. Verified 2026-08-31 by running both.
🔴 `--script` **without** `--play` or `--menu` refuses and says so. It used to
parse, be stored, and do nothing.
## 3. What is knowingly missing — not bugs
Four of the five main-menu destinations are **measured but not in this export**:
they live in other archives (`GP_SAVE_LOAD`, `GP_OPTIONS`, …). Pressing Ⓐ on them
prints what it would have opened and why it cannot:
```
(LOAD GAME) opens a screen this export does not carry:
The save-slot list is GP_SAVE_LOAD, not in this export. Destination MEASURED.
```
**EXTRAS is the only Ⓐ-into-a-submenu this milestone can walk**, which is why the
P5 gate rests on it.
`NEW GAME` is a deliberate gap of a different kind: the real chain is
NEW GAME → DIFFICULTY → SELECT DATA → the `S00A` movie, and the port **jumps to
the movie**, printing the two screens it skipped. That is a gap, stated out loud;
nobody should read the port's behaviour there as the game's.
## 4. What this container distorts
* **No GPU.** 720p Theora decodes **+6.7 % … +6.9 % slower than real time** here
(5 runs, both movies, on a quiet box). The boot's printed seconds carry that
deficit. It is a property of the machine, not of the port.
* **No sound card.** Godot falls back to a dummy driver, so **you will hear
nothing**. The audio is present and measurable —
`docs/port/AUDIO-VERIFICATION.md` answers every audio question without a
device, and `tools/port/verify-menu-audio` asserts it — but *"I heard it"* is
not available in here.
* **A leaked-object warning at exit** is engine-side, not the port's. Measured:
releasing every reference the port owns moves the count from 8 to 8.
## 5. Modding
`data/mods/` shadows `export/` by path. Each override is announced as it is read,
and at the end of a run any file that **can never apply** is listed:
```
mod: sprites/title/main_menu/ptbase.png <- data/mods/...
mods: 1 file(s) in data/mods can shadow NOTHING -- no such path in the export:
inert: sprites/title/TYPO_menu/pteff05.png
```
A file whose path exists in the export but was simply not read this run is **not**
listed. See `docs/port/MODDING.md` for the five rules the asset tree keeps.
## 6. Where the work is, and what P5's gate is waiting on
**P5's gate is the only one that needs a person, and it is not waiting on code.**
Everything above runs from `auto/port-p6-audio`.
🔴 **This section used to quote counts — "256 commits ahead, 58 files" — and they
were stale the moment they were committed, because committing them incremented
the count.** By the time anyone read it, it said 256 and the answer was 258. A
number written into a document meant to inform a decision **decays with every
commit either agent makes**, and the Decoder hit the same thing in their own
merge-state page one message after recording the class.
**So what follows are the invariants, which do not move, and the commands to
re-derive anything that does.**
| invariant | check | **passes when** |
|---|---|---|
| `main` is an **ancestor** of this branch — a fast-forward, nothing to resolve | `git merge-base --is-ancestor origin/main HEAD; echo $?` | prints **`0`**. ⚠️ The command itself prints **nothing** on success — without the `echo` a reader cannot tell success from failure |
| `main` is an ancestor of the Decoder's branch too | `git merge-base --is-ancestor origin/main origin/auto/build-ordinal-audit; echo $?` | prints **`0`**, same caveat |
| the two change sets touch **zero files in common** | `comm -12 <(git diff --name-only origin/main...HEAD \| sort) <(git diff --name-only origin/main...origin/auto/build-ordinal-audit \| sort) \| wc -l` | prints **`0`** |
| merging both produces **no conflicts** | `git merge-tree --write-tree HEAD origin/auto/build-ordinal-audit \| wc -l` | prints **`1`** — one line is the tree id; conflicts would follow it. **Read-only: this merges nothing** |
**Last run here: `0`, `0`, `0`, `1`.** A command published without a pass
condition is half a check — the reader gets a number and no way to know whether it
is the right one — so each row states what the right one is.
📌 **So the sentence is not "N commits behind", which sounds like something to
schedule. It is: two fast-forwards over disjoint file sets, mergeable in either
order with zero conflicts.** Counts if you want them:
`git rev-list --count origin/main..HEAD`.
### What a person is actually being asked to do
1. `godot --path port -- --boot --play`, then walk §2's table.
2. Say whether it behaves as described. **Not whether it matches the game**
that comparison is the oracle's job and is already asserted by
`tools/port/check-all`.
3. If it does, P5's gate is met and nothing else is blocking P6, which asserts its
own audio and has no human step.
⚠️ **You will hear nothing** (§4), and the intro takes ~157 s. `--menu=main_menu`
skips straight to the part being judged.

extends RefCounted
## The physical controller: the two buttons Godot does not bind, and the one
## input that is not an edge.
##
## 🔴 BOTH DEFECTS WERE REPORTED BY A HUMAN PLAYING THE PORT (2026-09-01), and
## neither could have been caught by the `--script` harness, because that harness
## sends `InputEventAction` — which bypasses the input map and is not an analog
## axis. The unattended P5 walk passed on every iteration while Ⓐ did nothing at
## all on a real pad. **A synthetic-input test asserts the code after the input
## map, never the input map itself.**
##
## ## 1. Godot 4.7.2 binds no joypad button to `ui_accept` or `ui_cancel`
##
## Measured on this exact build rather than remembered, because the answer has
## changed between Godot versions and the remembered one was wrong:
##
## ```
## ui_accept key:Enter, key:Kp Enter, key:Space <- no joypad at all
## ui_cancel key:Escape <- no joypad at all
## ui_up key:Up, JOYBTN:11, JOYAXIS:1- <- d-pad AND left stick
## ui_down key:Down, JOYBTN:12, JOYAXIS:1+
## ui_left key:Left, JOYBTN:13, JOYAXIS:0-
## ui_right key:Right, JOYBTN:14, JOYAXIS:0+
## ```
##
## That asymmetry is the whole bug report: navigation worked on the pad and Ⓐ/Ⓑ
## did nothing, which reads like a broken controller and is a complete input map
## for four actions out of six.
##
## The events are **added to** the built-in actions, never redefined. Declaring
## `ui_accept` in `project.godot` replaces the built-in wholesale, so the
## keyboard bindings would have to be restated there and would silently rot the
## next time Godot changes them.
##
## ## 2. A stick is not a button
##
## `ui_up`/`ui_down` are bound to **axis 1**, so the left stick navigates — which
## is correct, the real game accepts it too. But an axis emits a fresh
## `InputEventJoypadMotion` every time the value *changes*, and a real stick held
## at deflection jitters continuously. Every one of those events reports the
## action as pressed, so a held stick was one cursor step per jitter: the human's
## words were "moves the cursor too fast", and on a five-item menu it crosses
## faster than the eye follows.
##
## So the stick is **latched**: it fires once when it leaves the neutral zone and
## not again until it comes back. That makes it behave exactly like the d-pad,
## which needs no latch because a button already is an edge.
##
## ⚠️ **AUTHORED, NOT MEASURED — and deliberately the conservative half.**
## Whether the real game *repeats* while a direction is held, and how fast, is
## unknown; it is an oracle question. One deflection = one step cannot run away
## and cannot invent a rate. If the game does repeat, this is a difference a
## human will notice as "I have to flick it again", and the fix is a measured
## repeat interval — not a guessed one. Logged for the Decoder as `pad-repeat`.
## Godot's action deadzone for the `ui_*` actions is 0.50, so the latch must not
## arm below it — the action itself would not read as pressed and the step would
## be swallowed anyway, leaving the latch armed against a press that never
## happened.

## across the boundary and re-arms on noise, which is the original bug wearing a

## How long one turn takes, in keyframe units, for an element that spins — or 0.
##
## The rule is STRUCTURAL and narrow: exactly two keyframes, differing in
## **nothing but** `rotation_deg`, by a full 360. The period is the SPAN between
## the two poses.
##
## 🔴 THIS PARAGRAPH DESCRIBED THE PRE-FIX RULE WHILE THE BODY BELOW IMPLEMENTED
## THE CORRECTED ONE. It read: *"with the first timed and the second untimed. The
## period is the first keyframe's declared `t`."* Under the corrected record
## layout every pose is timed, so `b.has("t")` is always true, that rule returns
## 0, and the ring stops spinning — which is exactly the failure the body's own
## comment records and fixes. A doc comment and its function contradicting each
## other, with the doc stating the refuted version.
##
## Its disc-wide check, over this export: **16 of 212 elements match, and all 16
## are focus rings** — `ptbtneff01` on the five main-menu buttons and
## `ptbtneff02` on the three `EXTRAS` buttons, in both locales, every one of them
## declaring `t = 120`. Zero false positives. That matters because the rule is
## applied on the strength of a measurement taken on **one** button of one
## screen; a rule that also caught something else would be extrapolating from
## that measurement to elements nobody watched.
##
## ⚠️ It is a rule about SHAPE, not a decoded field. Nothing on the disc says
## "this loops". What the disc says is 0° → 360° over `t`; what the RE agent
## measured is that the turn repeats rather than stopping. Those are two
## different sources and the day a loop flag is decoded, this goes.
## The cycle length of a looping focus record, **derived in preference to authored**.
##
## The record header's `+0x08` says where the cycle restarts, and it is not the
## last keyframe's time: the plate's glow ramps 0→80→0 over 105 units inside a
## 120-unit cycle and rests dark for 15. The exporter now carries it as
## `focus.loop_length_units`, so the period comes off the DISC.
##
## `authored/timing.json` had 120 already, from a wall-clock measurement of the
## running game (≈2.37 s). **The two agree**, which is why this is a provenance
## change and not a pixel change — an emulator stopwatch and a field on the disc,
## sharing no instrument, landing on the same number. The authored value stays as
## the fallback and as that second witness.
##
## A DISAGREEMENT IS ANNOUNCED, never silently resolved. Preferring one number
## without saying so is how a measurement and a declaration drift apart for
## milestones without anybody learning that they had.

## Godot sets the blend mode on a CANVAS ITEM, not on a draw call, so an additive
## element cannot simply be drawn differently inside one `_draw()`. The measured

## mode and each run gets its own canvas item, ordered by `canvas_item_set_draw_index`.
##

## each -- LOSES A FRAME. `boot.gd` calls `view.queue_redraw()` from nine places
## and none of them reaches a child node, so the bands would paint the previous
## pose. A capture taken with `--script=wait` would have shown that as a plausible
## wrong answer rather than as an error. These items are filled synchronously
## inside `_draw()` instead, so there is no second node to keep in step.
## 🔴 CANVAS ITEMS MADE THROUGH `RenderingServer` ARE NOT OWNED BY THE NODE, and
## the first version of this file did not free them: Godot printed
## `5 RIDs of type "CanvasItem" were leaked` on every exit -- exactly the number of
## paint-order runs on the main menu. A node-owned child would have been collected
## for me; the reason for using the server directly is in `_band`, and this is its

visibly failed is the one nothing directs attention at.** The Decoder reached
this from the input side -- Ⓐ and Ⓑ were delivery-confirmed because they had

mine turned out to rest on a single entry that may have been measuring history.
So this checks what is checkable about a label, and is explicit that the rest is
not:
citations resolvable references in the `why` -- a `docs/` path that exists on
some ref, a commit sha that resolves, a capture filename
BARE a label whose `why` cites nothing a reader could go and open
DANGLING a citation that does not resolve anywhere in the repository
🔴 What it CANNOT do is read the cited page and confirm it says what the `why`

"""Date every open row in BLOCKED.md from history, instead of guessing.
`BLOCKED.md` is required to record the HANDOFF commit each row derives from, and
none of the rows in the two open tables do. The file itself says why: nobody
knows when most of them were written, and inventing a sha would be worse than
admitting there is none.
But git does know. A row's derivation is not a memory, it is the commit that
introduced the row -- recoverable with a pickaxe over the file's own history.
This prints, per row:
introduced the oldest commit whose diff added the row's key phrase
HANDOFF@ `git log -1 -- docs/port/HANDOFF.md` as of that commit
unread commits touching docs/re/ ON ANY REF that are not ancestors of
that commit -- decoding the row has never been read against
`--all`, not my own ancestry, and that distinction is the whole finding. Counted
against my checkout every row scores ZERO, which is true and useless: the
Decoder's live decoding sits on `origin/auto/no-disc-and-menu-captures`, `main`
is a hundred-odd commits behind it, and HANDOFF has not moved in four
milestones [refuted] -- 🔴 corrected 2026-09-01: **on `main`**. Flat, that
sentence is the claim this port WITHDREW in `BLOCKED.md` on 2026-08-30, where the
missing qualifier was recorded as carrying the whole meaning: HANDOFF has moved
over a hundred times, just not on the branch this checkout reads. The reasoning
below needs the qualifier to work at all -- the sha is constant BECAUSE `main`'s
copy is frozen, not because the document is. So a row can be derived from the
newest HANDOFF `main` has and still
be a day behind the decoding -- and the instruction to record the HANDOFF sha
CANNOT DETECT THAT, because the sha it asks for is constant.
That is the rot mechanism the 2026-08-30 audit found three instances of, and it
is not the one the header of BLOCKED.md describes.
Nothing here is authored. Every field is read out of git, and a row whose key
phrase has been rewritten since it was introduced reports `?` rather than a
plausible-looking sha.

# It said: "the pin is not on main, so this compares two decoder eras". I
# replaced that with "the eras render identically -- 0 pixels different on three
# screens". 🔴 **That measurement was void**: the two binaries I compared had the
# same md5. I built one in a worktree at the pinned tag and one from the
# workspace, and both commits carry the record-layout fix, so I compared a
# binary with itself and reported the zero as evidence.
#
# Rebuilt properly against `origin/main`, which is the genuinely stale era
# (`rest t=70 [12 70 80 -]` against the fixed `rest t=12 [0 12 70 80]`):
#
# title 0 px main_menu 0 px title_jp 74 507 px
#
# ✅ The eras DO change pixels, and `title_jp` is one of the seven bundles where
# they do -- reproducing the Decoder's figure exactly, under their flags and
# mine. My "--animated masks it" hypothesis was wrong too.
#
# ✅ BUT THE ERA STILL CANNOT EXPLAIN THIS SCRIPT'S ROWS, for a reason I had not
# established: BOTH SIDES OF THIS COMPARISON ARE THE FIXED ERA. The exporter is
# pinned to `formats-pin-2026-08-30` and this reference is built from the
# workspace, and a binary built from each has the SAME md5. There is no era
# mismatch here to explain anything. Right answer, wrong evidence, and the wrong
# evidence was a broken experiment.
#
# The real reasons are per-screen and already documented:
# title -- the ptloop SWEEP PHASE residual, max 6 / over3 790, unchanged
# across every renderer change since P1 (DECISIONS.md).
# title_jp -- the `--pose=rest` sparkle handling. Adjudicated against the
# oracle: the port's SHIPPED pose scores r +0.9994 against the
# game where the reference scores +0.8727, and `--pose=rest` is
# what this script compares.
# ⚠️ title_jp is ALSO an era-sensitive bundle, so if this reference is ever
# built from a different era than the exporter's pin, that row's cause changes
# and this note stops applying. Check the md5s before trusting it again.

#
# WHY THIS EXISTS. A 6-channel capture of the game's own output was analysed at
# length -- three controls, a drift test, a written-up negative -- and the file
# was corrupt. PulseAudio was remapping between two mismatched channel maps, and
# a 6-channel remap SILENTLY DROPS AND DUPLICATES: right duration, right channel
# count, plausible per-channel levels, no error anywhere. Two of the six channels
# were byte-identical copies of two others and two source channels were simply
# gone.
#
# The Decoder proved it with a control that needs no emulator and no disc: six
# channels each carrying a different tone through the same sink and the same
# `parec` invocation. Channels came back 400 / 3200 / 200 / 800 / 800 / 200 for
# an input of 400 / 800 / 200 / 1600 / 3200 / 6400 -- see
# `docs/re/audio-capture-channel-map-trap.md`. Setting the sink's `channel_map`
# to the guest's own and passing the same map to `parec` returns all six.
#
# THE DETECTABLE SIGNATURE IS AN EXACT DUPLICATE PAIR. Two channels of a real
# surround mix are never byte-identical over 70 s. Levels are not enough to catch
# it -- the corrupt file's per-channel peaks looked entirely reasonable, and it
# was only equal peak AND equal RMS to six decimals that prompted a hash.
#
# This is a NECESSARY check, not a sufficient one: passing it means the capture
# has no duplicated channels, not that it recorded the right thing.

# STARVATION: the second way a capture looks perfect and carries nothing.
#
# A monitor sink advances at WALL-CLOCK rate and substitutes silence whenever the
# producer is late. An emulator running below real time therefore yields a file
# of exactly the right duration, right channel count, no duplicated channels --
# and chopped into fragments with holes punched between them, thousands of times
# over. Envelope correlation against such a file is destroyed by construction:
# what dominates the envelope is the dropout schedule, not the content.
#
# Measured on the capture that prompted this: 35.6 % of frames silent on all six
# channels, 10 482 alternating runs, median burst 13.5 ms and median gap 3.9 ms
# -- a 17.4 ms period, 57 Hz. The Decoder measured the untruncated original at
# 39.3 % and 10 595 runs; the two agree.
#
# THE DISCRIMINATOR IS THE RUN STRUCTURE, NOT THE SILENCE FRACTION. Real audio is
# full of silence -- a voice track is more than half gaps -- but those are TENS of
# runs of HUNDREDS of milliseconds. Dropout chop is THOUSANDS of runs of a few
# milliseconds. So the test is: many short all-channel gaps.

# genuinely zero for milliseconds -- so neither the gap COUNT nor the median
# length separates them. The RATE does, by an order of magnitude in both
# directions, and 20/s sits between with a 1.6x margin below the bad case and
# 6x above the worst good one.
# TWO NUMBERS, BECAUSE ONE CANNOT SEE THE FAILURE NEXT DOOR.
#
# The first version of this tested the gap RATE alone, at 20/s. The Decoder then
# measured what a LARGER client buffer does, and the relationship is not
# monotonic: raising `PULSE_LATENCY_MSEC` keeps cutting the rate while total
# silence bottoms out and then doubles, because an over-large buffer starves in a
# few enormous holes instead of many small ones. Its 500 ms capture scores
# **1.3 gaps/s -- better than a genuine music bed at 3.3 -- while being 50 %
# silence**, and my bar passed it. Reproduced here on a file I hold: `bigholes`,
# a real bed with 350 ms holes punched in, is 46.3 % silence at 3.2 gaps/s.

# for the same control. Neither can be re-measured -- that control file was
# transient and is gone -- so there is no way to say which copy aged.
#
# That is the mirror of the trap the Decoder named the same day: they lost a
# finding because its only record was a script comment; this lost a digit because
# a finding had TWO records and nothing kept them equal. A number copied into a
# second place will drift from the first, and the drift is invisible because both

#
# `check-all` sat on two lines of output for over an hour; the cause was this

# bytes = exactly 8.0 s of 5.1ch/16-bit/48 kHz**, the full intended length, and
# ffmpeg then hangs with the artifact already correct on disk.
#
# Three formulations were tried and all three hang, all three producing
# BYTE-IDENTICAL output: the original, one with `-t 8` bounding the output, and
# one with explicit `asplit` feeding each `atrim` (the textbook fix for
# multi-use of a single input). So it is not the split, not the output stage,
# and the artifact is not in doubt.
#
# ⚠️ Worse than the hang: it LEAKS. An orphaned ffmpeg from this script's earlier
# `aloop` form was found still running after **9.5 hours**, burning CPU across
# runs nobody was watching. `boot.gd`'s own header already names this failure
# shape -- "it does not fail, it waits, and a job that waits forever reads as a

#
# So: bounded, and the ARTIFACT is checked rather than the exit code. That is

# tools/port/check-claims
#
# 🔴 WHY THIS IS A CHECK AND NOT AN AUDIT. The Decoder's rule -- *grep the corpus
# for the claim, not for the file you were working in* -- found a refuted sentence
# still shipping in this port's `manifest.json`, and a withdrawn one still
# standing in `DECISIONS.md`. Running that by hand finds the instances present on
# the day it is run. It does not stop the next one.
#
# So: a REGISTER. Each row is a claim this corpus has refuted, plus a marker that
# must appear near every occurrence. A hit without its marker fails the run.
#
# ⚠️ Two things learned building it, both from the other agent:
#
# * a "kept for the record" block STILL ASSERTS. Marking the heading superseded
# does not mark the sentence a reader lands on, so the marker must sit near
# the CLAIM, not at the top of the section.
# * naming a refuted claim keeps it greppable, so this check returns its own
# corrections as hits -- which is the point. The marker is what distinguishes
# "quoted while being refuted" from "still asserted".

# The first version matched a per-claim keyword -- "refuted", "WITHDRAWN" -- near
# the hit. Every one of its four failures was a quotation sitting INSIDE a
# correction whose wording happened not to contain the keyword: a table cell
# reading "standing, unmarked", a sentence reading "the real count was ten".
#
# Widening the window or adding synonyms until those passed would have been
# tuning a threshold until the answer came out right, which is the failure this
# corpus has spent a fortnight cataloguing. So the marker is a TOKEN THE AUTHOR
# PLACES: `[refuted]` near any quotation of a registered claim. It cannot be
# satisfied by phrasing, and its absence means exactly one thing.
#
# ⚠️ The cost is honest: every quotation must be marked by hand, and a new
# refuted claim means a new row plus marking its existing quotations. That work

# ─── THE WITHDRAWAL-TIME HOOK ────────────────────────────────────────────────
# The register enforces claims it KNOWS ABOUT; knowing about them was manual, and
# that is how ~8 claims were withdrawn this session and 0 registered. A sweep
# cannot fix it -- by the time you sweep, the withdrawal is already unpublished.
# The hook fires where the withdrawal is WRITTEN.
#
# A correction in DECISIONS.md has a shape: a heading carrying WITHDRAWN /
# CORRECTION / "refuted". A section like that containing no registered phrase is
# a death argued and never indexed.
#
# ⚠️ The register is passed in the ENVIRONMENT, not inlined. The first version
# pasted the rows into this file's own heredoc -- which made every phrase an
# unmarked quotation, and the checker flagged its own source. A tool that
# violates the rule it enforces by being written is worth a comment.
#
# 🟡 REPORTED, NOT ASSERTED: not every correction retires a CLAIM -- some fix a
# number, a scope, a wrong floor -- and forcing a row for those would push rows
# in to silence the check, the failure this file exists to prevent.
#
# ⚠️ AND IT WILL ALWAYS OVER-REPORT ON WELL-WRITTEN CORRECTIONS. The detection is
# "does this section contain a registered phrase", which requires the correction
# to QUOTE the dead claim. A good correction paraphrases it away: the JP heading
# now reads "does NOT go against the port", which does not contain the registered
# "goes against the port" [refuted] and is flagged despite being registered.
#
# The Decoder's resolution is the right one and costs the correction nothing:
# **the register entry is the verbatim home of the dead phrase; prose paraphrases
# freely.** They are different documents, so the phrase always has one exact
# place to live without any correction having to carry it. What follows for this
# hook is that its candidate list mixes "never registered" with "registered and
# paraphrased", and it cannot separate them -- so the list is a prompt to check,
# never a defect count.

"""Reconcile the numbers the CONTRACT states against the numbers the PORT ships.
`docs/port/HANDOFF.md` is the contract, and this port reads it from `main` --
where it is frozen at 926 lines while the live document, on the Decoder's branch,
is 4 111. Two days of deliveries addressed to the port landed on a page the port
does not open. Reading 70 unread sections by hand is how that gets missed again.
So the values are checked instead of read. Each check names a quantity, pulls it
OUT OF THE LIVE HANDOFF TEXT by pattern -- never restating it here, or this file
would be a third copy to go stale -- and compares it against the port's own
`export/` tree or `authored/` mapping.
Three outcomes, and the third is the point:
ok the contract and the port agree
MISMATCH they disagree; one of us is wrong and this says which values
ANCHOR the pattern no longer matches the contract -- the check has STOPPED
CHECKING. Reported as loudly as a mismatch, because a check whose
anchor has drifted passes forever while measuring nothing.
Reads the newest HANDOFF on ANY ref, not the working tree's, and says which.
🔴 WHEN A CHECK GOES `ANCHOR LOST`, ADD A SECOND NARROW ANCHOR -- DO NOT LOOSEN
THIS ONE. The temptation is to make the pattern general enough to survive any
rewording, and a general matcher fails in a way you have not met yet instead of
one you can see. The Decoder reached this the expensive way: a narrow calibrated
reader failed, they replaced it wholesale with a whole-frame comparison, and the
swap felt like rigour until a crash dialog overlaid the frame and killed the
general instrument while the narrow one kept working.

"""What KIND of error is left at the edges after tone is accounted for?
tools/port/edge-residual-kind [screen] # default main_menu
`verify-capture`'s `diff` column thresholds at 25 % and so only sees GROSS
displacement. Fitting a per-level LUT removes everything a tone effect can
explain. What is left on the main menu is concentrated 3.2x on edge pixels
(DECISIONS.md, 2026-08-31) -- and three things produce that: a misregistration,
an antialiasing difference, or a genuinely misplaced element.
THE DISCRIMINATOR IS THE SIGN, and it is the Decoder's, from their reply on
2026-08-31: a shift gives a residual with a CONSISTENT DIRECTION along the edge,
an antialiasing difference does not. Made concrete:
* shifted by (dx,dy): residual ~ dx*d/dx + dy*d/dy -- and the fitted SLOPE
IS THE SHIFT IN PIXELS
* blurred/sharpened : residual ~ -k * laplacian -- symmetric, no direction
EXIT CODES. 0 the report is trustworthy, 2 A CONTROL FAILED so the numbers below
it mean nothing. There is no 1: this tool classifies, it does not judge. A
correlation this tool reports is worthless without the two controls above it,
which is why they are not optional and not a flag.

`edge-residual-kind` fits the whole frame and excludes a GLOBAL translation. Its
own reach statement says the thing it cannot do: one misplaced element is a small
share of 38 752 edge pixels and would not move a whole-frame number. This tiles
the frame and runs the same discriminator INSIDE each tile, so a single displaced
element shows up as one hot tile with a local slope -- which is invisible to the
global fit by construction, not by accident.
Division of labour, agreed with the Decoder 2026-08-31: the residual map is the
port's (it needs the render beside the capture), the element inventory is theirs
(it needs the disc). This tool produces the map and NAMES NOTHING.

"""Which ELEMENT carries the disagreement with the capture? Rank them by suppression.
tools/port/element-residual [screen] # default main_menu
`edge-residual-map` gives hot COORDINATES, and turning those into elements needs
the design-space -> capture transform, which is a convention I would have to
assume. This needs no transform: the port has a mod tree, so shadow an element's
sprite with a transparent PNG, render, and diff the port's OWN two renders. The
pixels that change ARE the element, already in the comparison frame.
Reports, per element, on the pixels it actually paints:
* mean |residual| against the capture, after ONE global tone LUT
* the SIGN -- is the port drawing this element too dark or too bright
* edge versus flat -- an outline problem or a body problem
⚠️ SUPPRESSION IS BY SPRITE PATH, so elements sharing a sprite are suppressed
together and are reported as one row. `ptloop01` draws `pteff03.png`; the id and
the file are not the same thing.
EXIT 0 the report is trustworthy, 2 a control failed. No 1: this ranks, it does

what a peer HOLDS readable right now, from any topic branch, by anyone who

what a peer must be TOLD still needs a human to merge to `main`

ref already fetched in their checkout. This port read `main`'s 926-line HANDOFF
for two days while the live one sat on a branch it had already been citing by sha.
Same gap, opposite directions, and the fix in both cases costs one command. So
the command exists rather than the intention.

# * PulseAudio's monitor SUBSTITUTES silence. It advances on a wall clock and
# replaces audio that existed when the producer was late. Information is
# gone; deleting the holes compresses time unevenly and repairs nothing.
# DO NOT RUN THIS ON A MONITOR CAPTURE.
# * Xenia's ALSA writer PADS. It inserts silence between samples the guest
# emitted when its ring is empty (`alsa_audio_driver.cc:359`). Nothing is
# lost and nothing is overwritten, so removing the padding is EXACT -- it
# hands back the contiguous stream the guest produced.
#
# CONTROLLED, not argued. A real music+SFX bed (137.37 s, with 454 zero runs of

# Diff the port's render against a CAPTURE OF THE REAL GAME.
#
# tools/port/verify-capture main_menu
# tools/port/verify-capture # every screen with a capture
#
# THIS IS THE CORRECTNESS CHECK. `verify-screen` is the consistency one, and its
# own header has pointed at this file since P1 -- `tools/port/verify-capture` -- while
# this file did not exist. The port has had a harness comparing two renderers
# that share its assumptions, and none comparing it to the game.
#
# 🔴 WHAT THE `diff` COLUMN DOES NOT SAY. It counts pixels surviving
# `-threshold 25%` -- differing by more than ~64 levels. That is deliberate: it
# detects a missing or MISPLACED element, which is a large connected blob. It is
# blind to sub-threshold spatial error -- a one-pixel offset, a soft edge in a
# slightly wrong place, an antialiasing difference -- because none of that moves
# a pixel 64 levels.
#
# So `main_menu 0.06%` means NO GROSS DISPLACEMENT. It does NOT mean the
# geometry is right, and it has already been read that way by another agent:
# `docs/re/structures/title-residual-tone-vs-geometry.md` uses this screen as a
# tone-only positive control, citing this number as "geometry is essentially
# right". Measured 2026-08-31 against that capture: after fitting a per-level LUT
# -- the most general tone model there is -- the remaining residual is 6.94 on
# edge pixels against 2.20 on flat ones, a 3.2x concentration. A purely tonal
# residual leaves a per-level LUT exactly 0.00 (checked, by construction). The
# menu carries spatial error this column cannot see.
#
# ⚠️ That gap is not academic. `docs/re/captures/ORACLE-CAPTURES.md`: two
# renderers agreeing proves nothing, and this corpus has been bitten three times
# -- the dropped `pteff05` background, the scale-0 rect, and `rest()`. Every one
# was invisible to a render-vs-render diff and obvious against a capture.
#
# WHAT IT CAN CONCLUDE, and what it cannot:
#
# * ✅ STRUCTURE. Something drawn that should not be, or missing that should be,
# shows as a large connected region of difference. That is the failure mode
# the three above were, and it is what this tool is for.
# * 🔴 NOT a pixel score. The captures are NOT gamma-neutral:
# `capture ~= 255*(render/255)^g` with g ~ 1.34-1.49, and that ramp is THE
# GAME'S, not the capture path's (`docs/re/structures/ui-render-tone-curve.md`).
# So RMSE has a floor and driving it lower is fitting the ramp. This reports
# the raw difference AND the gamma-compensated one, and neither is a target.
# * ⚠️ A capture is ONE MOMENT. Several screens are still animating -- the
# title's two `ptloop` sweeps never stop -- and the focused button in a
# capture may not be the one the port focuses. Differences confined to a
# button or a moving element are expected; say which before calling anything.
#
# Geometry needs no correction: the corpus cross-correlated a render against
# `live-main-menu.png` over +/-6 px and the best alignment is exactly (0,0) at
# 0.9466. The captures are a 1279x675 top-left crop of the 1280x720 guest
# surface, so the render is cropped to match and nothing is scaled.

# 🔴 A MENU CAPTURE HAS A BUTTON FOCUSED, AND THE FIRST VERSION OF THIS TOOL

# was being compared to the oracle in a state the oracle was never in: 2 159
# differing pixels, of which 74 % sat inside the focus signature. Rendered with
# focus it is 531 -- 0.06 % of the frame, a 4x improvement that was entirely my
# harness posing the port wrong.
#
# `--menu=` applies `authored/flow.json`'s initial focus and `--script=wait`
# shoots one settled frame and exits.

# The only capture of a MEASURED focus state, and it was unusable until
# `--focus=` was made to work on the `--menu` path (it parsed, was stored, and
# was overwritten by the authored initial focus on every `_menu_enter`).
#
# It discriminates: rendering each of the five buttons focused against this
# capture gives 0.1355 % for `ptbtn04` and 0.70-0.82 % for the other four. The
# port's focus rendering identifies the right button by a factor of five.
"main_menu_options:$CAPS/live-main-menu-options-focused.png:focus:ptbtn04"
# ⚠️ THE TITLE IS POSED AT t=357.7 UNITS, NOT AT ITS SETTLE, and the time is
# MEASURED rather than chosen. The two `ptloop` sweeps are a continuous
# animation whose leaf group ends at t=600 with the quads parked off-screen at
# x=1521, so posing at the settle compares a still frame against a capture
# taken mid-sweep and simply omits them.
#
# t=357.7 is the Decoder's REFINED fit, and the refinement is worth knowing.
# Its first value, 355, came from the two per-draw alpha bytes alone and left
# an 11.5 px residual that looked like a pivot problem. Solving the same
# instant on the vertex POSITIONS instead gives t=357.88 and 357.58 to
# +/-0.12 units, against +/-1.54 and +/-1.89 from the alphas -- alpha moves
# only 0.27-0.33 levels per unit, so one byte of quantisation is worth 6-8 px
# of sweep. At 357.7 the centres land within 0.70 px and both alphas inside one
# level. THE 11.5 px WAS THE FIT'S RESOLUTION, NOT GEOMETRY.
#
# ⚠️ And there is no pivot correction: the leaf pivot is (200, 90) on a 399x180
# sprite, so it is the centre to within half a pixel -- checked here against
# the export rather than taken.
#
# ⚠️ It is NOT the time that minimises the difference: t=390 measures 1.65 %
# against 1.82 % here. Picking that one would be fitting the pose to the
# score, which is the thing this harness exists not to do.

# the capture is demonstrated at rest (five frames over 6 s, 0 px change in
# the logo block while 5-8 % of the frame moves).
#
# 🔴 THIS ROW EXISTS BECAUSE SCORING THE WRONG FRAME COST A WRONG CONCLUSION.
# `verify-screen` poses at `--pose=rest`, which for this screen lights every
# `ptlogo_back2eff*` sparkle at its own peak simultaneously -- `rest` for those
# elements IS the peak of a 4-unit flash. That frame is fine for the
# consistency check it was built for and must never be scored against a
# capture: doing so put the port at r +0.7462 against the reference's +0.8727
# and I wrote up that the port had moved away from the game. Posed as it
# SHIPS, the same block scores **+0.9994**.
"title_jp:$CAPS/live-title-jp-at-rest.png:settled::1279x675+1+45"
# A SECOND title comparison, and the most sensitive row this tool has.
#
# `live-title-press-a.png` is the title WITH the plate. Posed at t=237 -- inside
# the plate's own 8-unit opaque window, t=236-238 -- the port matches it at
# **0.00093 %**, two orders below every other row. That makes it the best
# regression detector here: anything structural that moves will show.
#
# ⚠️ The instant is FITTED, not measured: 237 is where this capture's content
# places it, found by sweeping. That is legitimate for choosing which frame to
# compare against -- every row does it -- but it is not a claim about the game,
# and the 0.00093 % is therefore a floor for THIS pose, not a general accuracy.
#
# It also closes the systematic-error question the leaf sweep left open. Two
# independent captures fit at two DIFFERENT phases -- this one at 237, the
# no-plate one at ~400 -- and both to 0.01 % or better. A geometry error in how
# the sweeps are drawn would leave a floor in both. Neither has one.
# 🔴 THIS ROW IS POSED AT THE PLATE'S BLIND PHASE, and it cannot see the plate's
# highlight at all. `--loop-phase=0` pins the looping-focus clock, and
# `ptbtn00f` -- the plate's own highlight, which the GAME draws ADDITIVE
# (docs/re/data/blend-bit-vs-oracle.txt, entry 2) -- contributes EXACTLY 0 px at
# phase 0 and 22 000-29 000 px at phases 20..100. Measured 2026-08-31 by
# shadowing its sprite and diffing.
#
# So switching that element to its measured additive blend moved 26 319 px at
# phase 20 and reported ZERO here. This row's 0.09 % is real and unaffected; it
# simply says nothing about the pulse. A capture at a NON-ZERO loop phase is
# what would let this row see it, and none exists -- filed in BLOCKED.md.

# structural difference is 0.354 % at y=520 against 8.9-9.1 % five pixels
# either side and 17-52 % further out. A 25x drop over five pixels.
#
# ⚠️ Its residual is NOT the port's error. The port reproduces the same band of
# `live-title-press-a.png` EXACTLY (0.000 %), and the two captures differ from
# each other by 0.301 % -- two thin horizontal strips, 248x5 px and 206x1 px,
# the shape of a sub-pixel edge difference rather than a state difference. So
# 0.354 % is very nearly the oracle-to-oracle gap and this row's job is to stay

# Check the port's boot pacing against captures of the real game.
#
# tools/port/verify-dwell
#
# WHY THIS IS A TOOL AND NOT A ONE-OFF. Doing it by hand once already refuted a
# 🔴 I had filed myself: `docs/port/BLOCKED.md` said `rest.t` was the wrong settle
# landmark AND that "everything the sequencer paces off it is therefore late".
# The first half is true; the second was wrong, and I nearly re-paced screens
# that already matched the game to 0.05 s.
#
# ⚠️ A PORT'S TRANSITION INTERVAL IS NOT THE ORACLE'S VISIBLE SPAN. They differ
# by the black hold between screens, and confusing the two cost this corpus 0.6 s
# once and 0.48 s on the plate delay. So the comparison here is explicit: the
# port's interval is checked against the oracle's span PLUS the measured hold.
#
# 🔴 AND THE VERDICT DOES NOT COME FROM THE FILMSTRIP ANY MORE. It used to
# measure ink spans from `--film` frames. The boot's black hold is 0.17-0.23 s
# (HANDOFF Q7) -- shorter than the 0.25 s cadence meant to observe it -- so when
# the black frame fell between samples two screens merged into one span and this
# tool reported `developer logos` as 93 s against an oracle of 3.5 s. Filming at
# 0.1 s made it WORSE: 2.5x the screenshots slows the run enough that the capture
# catches up in bursts, and the publisher span came back as 7.80 s.
#
# The sequencer already knows exactly when it changed screens and prints it.
# Sampling a picture to rediscover a number the program can state is how this
# went wrong. The filmstrip is kept, and marked advisory.
#
# THE EXPECTED NUMBERS ARE THE ORACLE'S, NOT THE PORT'S: three cold boots from
# `docs/re/boot-order-and-splash-dwell.md`, quoted as a test fixture. Nothing in
# the port derives them and nothing may.

# The input map, and the stick latch -- asserted against Godot, not reasoned about.
#
# tools/port/verify-input
# tools/port/verify-input --control # each check fails when its subject is removed
#
# 🔴 WHY THIS EXISTS. A human played the port on a real controller and Ⓐ did
# nothing. Skipping the intro did nothing; opening a submenu did nothing. The
# unattended P5 walk had passed on every iteration while this was true, and the
# reason is exact:
#
# `--script` sends `InputEventAction`, which BYPASSES the input map.
#
# So the harness asserted every line of code *after* the input map and nothing
# about the map itself -- and the map was missing half the actions. Godot 4.7.2
# binds NO joypad button to `ui_accept` or `ui_cancel`, while it binds the d-pad
# AND the left stick to `ui_up`/`ui_down`. Four actions worked on the pad, two
# did not, which reads as a broken controller.
#
# The second defect had the same blind spot: `InputEventAction` is not an analog
# axis, so the harness could not have seen that a held stick fires once per
# jitter. The human's words were "moves the cursor too fast".
#
# ⚠️ THE GENERAL LESSON, worth more than either fix: **a synthetic-input test
# cannot assert the input map.** Anything injected below the map is evidence
# about the code above it only.
#
# ## The control, and what it can and cannot cover
#
# 🔴 The first version of `--control` inverted ALL NINE assertions and demanded
# every one fail with the fixup skipped. Seven of them do not depend on the
# fixup, so it reported them as broken -- a control that fails a correct check
# is the same defect as one that passes a dead check, and this file would have
# shipped claiming its checks were untrustworthy. Each check now names its
# SUBJECT, and the control removes exactly that subject:
#
# bind -- skip `Gamepad.bind_missing()`; the check must fail
# latch -- run the same events through no latch at all; the count must differ
# godot -- NOT CONTROLLABLE HERE, and said so rather than faked. These assert
# what Godot itself binds. There is nothing of ours to remove; they
# exist to make a future Godot dropping the d-pad a failing check
# instead of a bug report.

#
# This is the P6 gate check. P6's gate is "sound on the P5 gate", and until this
# existed the only evidence for it was that `audio.play("move")` appears in
# boot.gd -- which is evidence that a call is written, not that a sound reaches
# the Master bus. Those differ: the black hold was implemented, called, and
# emitted nothing for five milestones.
#
# It needs NO SOUND CARD. Godot records the Master bus to a WAV under the Dummy
# driver (docs/port/AUDIO-VERIFICATION.md section 2).
#
# WHAT IT CONCLUDES, and what it must not be read as:
#
# * ✅ that a cue REACHES THE BUS when a press does something;
# * ✅ that a press bound to NOTHING is silent, byte for byte;
# * ✅ that two presses of the same action play the SAME cue;
# * 🔴 NOT that the cue is the one the GAME plays. That binding is HANDOFF Q8,
# measured by the Decoder, and nothing here re-measures it. This tool cannot
# tell a correct cue from a confidently wrong one.
#
# ⚠️ Cue LENGTH is deliberately not asserted. The audible part of a cue is much
# shorter than its wave -- the music bed masks the tail -- so "elevated for

"""Is the transcode faithful to the source? Decode both, align, subtract.
`AUDIO-VERIFICATION.md` §1 states this as the question P4 actually raised and
gives the method, and nothing implemented it. `verify-video-audio` deliberately
does not: it proves Godot emits non-silence and says in as many words that a
difference RMS without alignment is meaningless. So the gate has rested on level
and non-silence, and the fidelity claim has never been made.
The doc names three ways the measurement lies, and all three are handled here
rather than hoped about:
ALIGNMENT a one-sample offset makes the difference nearly as loud as the
source. Cross-correlated coarse-to-fine BEFORE subtracting, and
the search REFUSES when its best lag sits on the boundary --
printing the range beside the answer, so an edge reads as an
edge.
CHANNEL LAYOUT the source is 5.1 and the transcode is stereo. The source is
folded with `video.rs`'s own `DOWNMIX_51` -- read out of the
manifest's recorded command, not restated here -- so both sides
are the same fold.
A PARTIAL FILE `ffprobe` once reported 33 s for a 137 s transcode because the
encode was still running. Duration and mtime are checked, and a
file written in the last 60 s is refused.
THE SEEK `-ss` before `-i` returned 4.6 s of AUDIO for a 4.0 s request on
this WMA Pro source, so the two windows covered different audio.
Not in §1. ⚠️ NARROWED after the Decoder checked it: on this
disc the VIDEO container-seek is EXACT -- a frame taken at 20 s
via container seek is byte-identical to one from a full decode.
So it is a property of the AUDIO STREAM, not of `-ss` placement
as such, and a check that only looked at video would clear a
path still unsafe for audio.
🔴 AND IT RUNS ITS OWN KNOWN NEGATIVES. A fidelity check that has only ever
returned "faithful" is the unfalsifiable clean run this project keeps finding:
`--control` compares the source against itself (must be near-perfect) and against
the OTHER movie (must be near 0 dB down).
⚠️ **REPORT ONLY. THIS DOES NOT YET PRODUCE A VERDICT**, and it is committed in
that state deliberately. It has reproduced four distinct ways the measurement
lies -- three that §1 names and one it does not -- and each was found by a
diagnostic rather than by reasoning. It still reports the difference signal
LOUDER than the source, which cannot be true of two aligned signals at equal
level, so the remaining fault is on this side of the instrument.
A tool that says "not faithful" while its own alignment is broken would be worse
than no tool: it would put a false defect on the exporter. Committed so the next
iteration starts from four known traps instead of from four lines of shell.
