80042cb765 port: newly exported screens are REPORTED as uncompared, not failed and not allowed
Adding GP_OPTIONS put 14 screens into verify-screen's population that have never
been compared by anyone. All 14 read DIFFERS at means of 10-60 against 0.02-7.3
for the calibrated set -- which says nothing yet, because nobody has looked at
one of them, and because both the allowance AND the reference renderer were
built against GP_TITLE.

Failing on them would put the suite red for an uninvestigated state -- the wall
of meaningless failures the display guard exists to prevent. Adding them to the
allowed set would assert they are explained; verify-screen's own header is
emphatic that 'allowed' means 'measured, cause open', not 'ignore'.

So they get their own line naming them as NEVER COMPARED. The discriminator is
the sprite group in the manifest path, so a screen becomes assertable when
somebody moves it into the calibrated population deliberately, rather than by an
export widening underneath the check.

This is the risk I flagged before creating it, measured rather than assumed.

44a6cb6065 port: the display-restart recipe omitted the LOCK file
check-all's guard printed 'rm -f /tmp/.X11-unix/X<n>' and nothing else. Removing
only the socket leaves /tmp/.X<n>-lock behind; Xvfb then exits 1 immediately and
the next command still reports no display, which reads as the restart having
failed for a deeper reason rather than as an incomplete recipe.

Hit three times across this project, each time following the printed recipe. The
fix was visible in Xvfb's own stderr the whole time and nobody had read it --
the guard was written to save exactly that step, so an incomplete guard is worse
than none here.

2d2caccd75 port: check-citations gave a FALSE RED on a freshly pushed peer file
A citation added minutes after the other agent pushed the file it names resolved
NOWHERE, because this scans local refs and the local ref was stale. The citation
was right and the check was wrong. It now says so in the failure text and tells
the reader to fetch before editing.

A check that cries wolf is worse than no check -- and this one had just been
teaching me to distrust a correct citation.

🔴 Separately, my own slip: I ran this as '<check>; git commit' instead of
'<check> && git commit', so the commit landed while the check was red. The guard
was in the command and I had disabled it by punctuation.

ac1371cda3 port: F6 FOUND -- the gate was declared data the renderer was discarding
The sweep starts early because ScreenView drew a leaf WITHOUT multiplying its
parent's alpha in. ptloop01/ptloop02 declare 0:0 70:0 100:255 238:255 250:0, so
the sweep is invisible until t=70 and full at t=100. The port has had that ramp
in its export the whole time and was throwing it away at the draw call.

Three changes:

1. Parent alpha multiplies into the leaf's. This file asserted the opposite,
   arguing from the sweeps being drawn while their parent had expired -- but that
   could not separate 'the leaf wins' from 'the parent is ignored because it
   draws nothing', and its own comment said so and named the interval that would
   settle it. Measured there: dividing the leaf's declared curve out of the drawn
   alpha pins the implied parent at 255.0 (+/-1.5) over hundreds of frames while
   the drawn alpha swings 242 -> 132 -> 145.

2. rate 0.5, calibrated against a DECLARED interval (ptloop01's own 30-unit ramp)
   rather than captured frames: two runs differing 2x in frames give 0.4795 and
   0.4667, 2.7% apart. This number was 0.514, withdrawn, now reinstated at 0.5 --
   what failed the first time was quoting a rate in presents, and the ratio was
   discarded along with the frames.

3. The 107-unit authored offset is DELETED, with its guard tool. It came from a
   ratio measured against an element identified only by screen position; the
   declared ramp needs no such identification. Deleting an authored value because
   the data already says it is the outcome PORT-MISSION asks for.

Also reverted, same day I made it: removing the transparent-parent skip. I read
'the game submits the sweep ~950 frames past its parent's expiry' as the leaf
outliving the parent. It does not follow -- a draw submitted at alpha 0 is still
a draw, and submitted is not visible. With the multiply, skipping on a
transparent parent IS multiplying by zero.

VERIFIED, pre-registered before running, via --probe-leaf:
  u= 60 -> no draw at all           (predicted: parent alpha 0.00, gated off)
  u=100 -> leaf_t 50.0,  x -439     (predicted 50.0, -439)
  u=236 -> leaf_t 118.0, x -167     (predicted 118.0, -167)
verify-capture: every row unchanged.

⚠️ BUILD-SENSITIVE: builds 5 and 6 of GP_TITLE declare these records as a single
flat a=255 with no ramp. This export reads the ramped build; if that changes the
gate disappears silently.

af10a2ec3c port: F6 -- adopt the sweep onset as a measured RATIO, and fix the guard that disabled it
Onset: 0.500 of (title first visible element -> plate onset), measured by the
Decoder as 0.489 and 0.507 across two independent captures, 3.7% apart. A RATIO,
which is the point -- it needs no clock, and every unit-valued figure from those
captures has been withdrawn: the rate because frames are presents (1168 vs 600
for the same animation), the '+40 units' because its conversion put
title-start->plate at 75 units where the declared data puts the plate at 238, a
3.2x conflict that is still open and is F4's.

Resolved against THIS export: 0.500 x (214 - 0) = 107.0 units.
tools/port/check-leaf-onset recomputes it and fails if a re-timing moves the
anchors; it has a selftest in both directions and is in check-all.

🔴 AND THE ADOPTION WAS A NO-OP UNTIL THIS COMMIT. leaf_clock() read
'if start < 0.0 OR rate <= 0.0: return screen_units', so when the withdrawn rate
went back to null the adopted OFFSET stopped applying too -- silently, while
authored/rendering.json still stated it. The two fields are independent now.

It was caught only because the offset was re-verified by PROBING THE RENDERER
instead of re-reading the file I had just edited. Both my earlier verifications
of this feature passed while it did nothing: one compared frames that were all
being forced to the same pose, the other ran when both fields happened to be set.

Verified, pre-registered before running, via --probe-leaf:
  title u=236 -> leaf_t 129.0, x -123   (predicted 129, -123)
  title u=400 -> leaf_t 293.0, x  533   (predicted 293,  533)

Effect: at the plate's arrival the sweep sits at x=-123, just entering the frame,
where before it was at x=305, well across it.

359f0d8bff port: fit-trajectory -- position carries the clock, alpha carries almost nothing
Answering the human's 'what is holding you up': two agents spent three exchanges
on ALPHA while the answer sat in a POSITION series neither of us compared to
anything.

The arithmetic that should have been step one: the Decoder's quoted sweep centre
-1.690 read as NDC is -441.6 px, and the declared position at leaf t=0 is -439.5
px. A 2 px agreement on a 2160 px travel -- so the game's sweep begins
travelling at leaf t~0, the same as the port.

That CONTRADICTS my own earlier framing on this page, which blamed ~135 units on
the leaf clock. If the game's leaf clock also starts at 0 then F6 is a
visibility question, not a clock question. Flagged rather than rewritten: it
rests on two numbers relayed in a message, which is what should be read from the
repo instead.

The tool: solves x(frame) ~= declared(t0 + rate*frame) for both parameters and
reports the RESIDUAL, which says whether the model was right at all. Selftest
runs both directions -- recovers a known clock to 0.09 px and rejects a
wrong-shape series at 81.9 px against a 20 px bar. In check-all.

77320d5e41 port: put verify-menu-audio's control in check-all
Every other assertion in check-all has a control; audio was the one that did
not, which is how it went weeks unable to fail. Control measured just now: with
move absent from the baseline the diagonal reads +0.000, the check reports 'at
least one cue is not sounding' and exits 1.

94506ec247 port: verify-menu-audio could not FAIL -- the verdict never reached an exit code
It computed ok, printed a red line when a cue was silent, and the python had no
exit path at all, so it returned 0 every time while check-all registered it
must-pass. A cue could stop sounding and the suite would print the failure and
stay green.

This project's recurring defect one level up: not an instrument sitting below
the thing under test, but one that SEES the failure and does not report it.

The diagonal now exits. The no-op-silence and cue-order lines stay REPORTED --
both carry documented cross-run instability (whole-buffer recording shifts; a
0.15 margin this file's own comments show reaching 0.109 on a sounding cue), and
making either binding would produce red on correct audio.

--control feeds it a walk in which move never sounded, built from the tool's own
suppression machinery, and requires it to fail.

8477242656 port: a check that measures CHANGE, run against the defect it was written for
Closes the two items the play-test left after the fix landed.

1. tools/port/verify-motion, wired into check-all with its control.

It films a REAL boot -- no --time, no pinning -- and hands it to
tools/motion-census. The window is the DECLARED build-in (publisher t=0..45,
0.75 s at 60 units/s), so it asks about the interval the disc says is animating
and nothing else.

🔴 BOTH SIDES MEASURED, not one measured and one assumed. I reverted the single
operator in pose_at, ran this check against the defect, and restored it:

  broken (ASSIGNS the settle instant)   40 %   and it FAILED
  fixed  (clamps to it)                 86 %   and it passed

The bar of 60 sits mid-gap: 20 points above the defect, 26 below the fix.

🔴 AND MY FIRST VERSION OF THAT BAR WAS JUSTIFIED BY A NUMBER I HAD NOT
MEASURED. It claimed "~40 points of clearance on both sides"; with a 1.0 s
window the real clearance was 5 points, because that window includes 0.25 s of
legitimate hold and dilutes the signal. A bar defended by an unmeasured number
is this whole check's own defect, one level up. Corrected with the measurements
and the sequence stated.

The control runs FIRST and is not optional: motion-census --selftest drives a
fade, a switch and a frozen film through the same loader and floor. If it cannot
separate those three, every number the check reports is decoration. Then the
--control mode builds a frozen film from the port's own pixels -- one real boot
frame repeated -- and requires it to FAIL. It scores 0 %.

One defect in the check itself, caught by running it: `ls | head` under
`set -o pipefail` exits 141 before asserting anything, and a check that dies
before checking looks a lot like a check that passed.

2. BLOCKED.md H2 corrected from  to 🟡, against myself.

The MECHANISM half stands -- no post-process pass, the blur is a baked companion
texture. The BEHAVIOUR half was false and the row asserted it: I wrote "the port
draws all seven quads -- verified by a frozen sweep". True, and it did not mean
what I used it for. A frozen sweep drives the clock BY HAND. It proves the
renderer can draw pose N and says nothing about the poses being drawn in
sequence while running.

All three of my instruments passed the defect -- frozen sweep, a 0.01 % settled
comparison (a frozen screen matches a settled reference PERFECTLY), and an
achieved-fps counter (identical pixels 25x/s score like animating). Every one
measured throughput or a pose; none measured CHANGE. Same shape as
InputEventAction bypassing the input map.

Not settled: the ~1.0-1.2 menu residual; findings 3 and 4's remaining halves.
Both were explicitly deferred by the human until this was fixed, and it now is.

08ed3dd17e port: the splash never animated -- pose_at ASSIGNED the settle instant instead of clamping to it
The 2026-09-02 play-test: "the logos just switch, I cannot discern any animation
at all." Reproduced, diagnosed, fixed, and gated by a film.

REPRODUCED FIRST, as instructed. tools/motion-census needed Pillow, which this
container has no pip for, so it got an ImageMagick fallback that shims only the
four Pillow calls it uses -- the census arithmetic, the MOVED floor and the GRID
are untouched. Its --selftest passes on that backend with the human's own
numbers: fade 97.4 %, switch 2.6 %, frozen 0.0 %. A shim that distorted pixels
would fail its own control.

  publisher   0.30 s moving then 3.30 s FROZEN   (human: 0.30 then 3.20)
  developer   0.40 + 0.25 split then 2.45 FROZEN (human: 0.35 + 0.25 then 2.40)

Matched to within a frame.

THE CLOCK WAS NEVER THE PROBLEM. view_units advances 2.8-3.0 per frame, smooth,
~60 units/s, no stalls -- the play-test's candidate list can drop "the group
clock not integrating" and "advancing by keyframe index".

THE POSE WAS. Measuring the sharp logo's own rect frame by frame: 0.40549 flat
from unit 7.9 through 28.2 -- the same value it holds at 45 and beyond. It was
already FULL before its declared ramp (15 -> 30) began.

Cause, in ScreenView.pose_at:

    t = settle_instant if settle_instant >= 0.0 else minf(t, settle_units(element))

The comment above it says "stop at the hold". The else-branch clamps. This half
ASSIGNS, so from a screen's first frame every element was posed at the settled
instant and no build-in was ever drawn. The asymmetry is the whole defect, and
`--time` sets `frozen`, which skips the clamp -- which is exactly why my frozen
sweep "proved" the companions were drawn and proved nothing about running.

Fix: `minf(t, settle_instant)`. One operator.

⚠️ AND THE HOLD IS NOT THE BUG. The Decoder measured the game holding one picture
for 3.34 s on this screen -- LONGER than the port's 3.30 -- because palogo_sqex
declares 205 of its 255 units as a flat plateau. The play-test's "a fade does not
hold one picture for 3.20 s" would have sent me to delete the one correct part.
Clamping keeps the plateau exactly.

GATED BY A FILM, not a still:

                        before        after      game (Decoder)
  publisher build-in    0.30 s        0.60 s
  developer build-in    0.40+0.25     0.95 s continuous
  splash moving         12.0 %        24.8 %     21.2 % / 27.8 %
  distinct luma states  120           152
  longest frozen        3.30 s        3.30 s     3.34 s

🔴 AND IT LOOKED LIKE A 10x REGRESSION AGAINST THE ORACLE, WHICH IT WAS NOT.
verify-capture went publisher 2.17 -> 22.58, title 14.11 -> 67.07. Cause: it
shoots two frames after load and got the settled pose ONLY because pose_at
assigned it. Its own comment says so -- "the 0.01 % agreements on both splashes
were measured through that accident."

So the `--screen --capture` path now advances the clock to the settle instant
explicitly before shooting, which is what the tool was always asking for. Guarded
on `not _frozen`: `--time` means the caller wants THAT instant, and overriding it
would reintroduce the silent-ignore this replaces.

Every oracle row is back to its pre-fix value to the digit: publisher 2.17
(0.01 %), developer 3.05 (0.01 %), title 14.11, main_menu 13.02, extras 13.10,
title_plate 13.04. The port animates AND still matches the settled captures.

Not settled: motion-census is not yet wired into check-all -- next, and
deliberately not rushed at the end of a long iteration.

3cc3400a96 agents: the splash does not animate, and three instruments could not see it
Some checks failed

CI / WASM — Web (push) Failing after 6m32s
CI / Formatting (push) Failing after 1m13s

A human on a GPU at ~140 fps: "the logos just switch, there is no animation at
all." Measured from a real boot with --film at 0.05 s, then per-frame change:

  splash moves        1.30 s of 7.95 s = 16.4 %
  publisher splash    0.30 s of motion, then 3.20 s FROZEN
  developer splash    0.35 s + 0.25 s, then 2.40 s FROZEN
  distinct luma states in 7.95 s   26

A 45-unit build-in cannot be drawn in 26 states, and a fade does not hold one
picture for 3.20 s. The frame counter says 24.8 fps achieved; both are true --
the port is DRAWING 25 times a second and CHANGING almost never.

🔴 Why every check passed, which matters more than the bug:

  frozen sweep     drives the clock BY HAND -- proves the renderer can draw
                   pose N, never that the poses are drawn in sequence
  settled compare  0.01 % against the capture -- a screen frozen 84 % of the
                   time matches a settled reference PERFECTLY, that is what
                   frozen means
  achieved fps     counts frames DRAWN -- the same pixels 25x/s scores
                   identically to animating

Every one measured throughput or a pose. None measured CHANGE. Same shape as
InputEventAction bypassing the input map: the instrument sat below the thing
that was broken, so the break could not appear in it.

tools/motion-census closes the class. It measures change and nothing else, and
its --selftest asserts it separates a fade (97.4 % moving) from a switch (2.6 %)
from a frozen film (0.0 %) -- a detector that cannot tell those apart would
report the same green line on all three.

Both briefs: this is the SOLE focus. The port reproduces before changing
anything and gates every fix on a film rather than a still. The decoder maps the
whole pipeline end to end -- disc bytes, the game's per-frame update (does it
interpolate between keyframes or hold?), what is submitted per frame, and what
Canary does to it before a capture records it -- delivered as a SERIES, not a
settled value.

The port should also record the refutation against itself: H2 reads ANSWERED on
the strength of the frozen sweep. The mechanism half stands, the blur is a baked
companion texture. The behaviour half does not.

07da4f167f port: hold at 60 against a better 120, audit the switch, and name its falsifier first
The Decoder measures 120 units/s with a content-hash experiment carrying the
controls the withdrawn version lacked -- a static texture hashing constant (1
change in 403 samples) and movie luma not constant (102 distinct) -- against
pre-registered bands the observed 0.5739 falls inside. It is a better experiment
than either it replaces.

THE PORT HAS NOT MOVED. It is their third position on this number in one day,
reach is one boot, and they said themselves that a second independent boot before
a timeline is rewritten is the defensible call. Agreed.

⚠️ And 60 is not defended either -- its bracket was withdrawn this morning. Both
numbers are undefended. The port keeps the one it ships because switching on a
single capture is a worse failure than holding on none. That is the whole
reasoning and it is not evidence about the game.

 THE AUDIT THEY ASKED FOR COMES OUT CLEAN. "If seconds are baked in anywhere,
they all move." No seconds are baked into the timeline: every second this port
prints or acts on is computed as units / keyframe_units_per_second at the point of
use -- settle_time, exit_time, _overlay_quit_at, the boot log. audio.json's
loop_start_s / loop_end_s ARE seconds and correctly do NOT follow the constant;
they are positions in an audio file with no keyframe unit in them. So the switch
is one number in one file.

🔴 ONE EXCEPTION, AND IT WAS HIDING BEHIND A COMMENT ABOUT NOT DRIFTING.
tools/port/verify-dwell read black_hold_units from the authored file "so it cannot
drift again" -- and then divided by a literal 60.0. The value could not drift; the
conversion could, and would have gone silently wrong the moment the constant moved,
which is under active dispute right now. Harmless only because the hold is 0.
Fixed to read the rate from the same file it already opens.

That is the third time in this corpus a `why` has described a property the code
did not have, and the first where the comment and the defect were one line apart.

📌 AND THE FALSIFIER IS PRE-REGISTERED, BEFORE ANY SECOND BOOT, in
docs/port/units-per-second-switch-readiness.md. At 120 every declared interval
halves: the plate lands at 1.967 s, the publisher splash runs 2.125 s and the
developer 1.750 s. Three cold boots measured those splashes at 4.30/4.60/4.37 and
3.51/3.50/3.37.

So 120 and the dwell corpus cannot both be right in wall-clock seconds -- the same
collision that killed the 35 units/s proposal from the other direction, arriving
from the opposite side. Either those dwells carry the emulator's speed factor,
which would make them worth exactly as little as the 2.13 s route the Decoder has
already declined to lean on, or 120 is wrong. Naming that now is the point of
writing it before the boot rather than after.

What would move this port: a second independent boot agreeing, AND a statement on
whether the cold-boot dwell corpus survives the same speed-factor objection that
the 2.13 s route does not. The first without the second leaves a 2x contradiction
standing between two numbers the port would then hold at once.

Not settled: the constant; the clock origin, which every ratio and count above
survives untouched; the ~1.0-1.2 menu residual; the allowance's grep trigger.

b42ff385ed port: my 12-unit bracket is withdrawn, and 41 % of my own doc citations did not resolve
Two things, and the first is a refutation of mine that lands.

1. THE 12-UNIT BRACKET IS WITHDRAWN. It excludes nothing.

I kept 60 units/s on the ground that "12 declared units measured at 0.14-0.30 s
gives 40-86 units/s, so 120 is excluded". The Decoder refuted it and I checked
the arithmetic myself:

  120 units/s predicts 12 units in 0.100 s -- BELOW the sampler's own 0.125 s
  resolution, which the source doc states in its own words ("at a sampling
  resolution that cannot do better"). A 0.125 s sampler reports such an interval
  as about one sample, ~0.125-0.14 s. So the 0.14 s low end is the INSTRUMENT'S
  FLOOR, and 12/0.14 = 85.7 is an upper bound produced by dividing by a floored
  duration. It is the value 120 predicts once the sampler is accounted for.

🔴 And the deeper error is mine rather than the arithmetic. I argued the leg
survived because it "never touched a frame count". True, and INSUFFICIENT: every
wall-clock duration off Canary is true/speed_factor, so apparent units/s = true x
speed, and the speed factor is precisely what makes the three routes disagree. I
checked the leg for the WRONG CONTAMINANT. Frame-free is not clock-free, and on
this emulator clock-free is the property that matters.

What survives is the half I did not lead with: the declared 12 units are
independently confirmed as SIX FRAMES by screen-transitions.md's 255/6-per-frame
ramp, with no wall clock in it. That is evidence about units per FRAME -- never in
dispute -- and silent about units per second.

So 60 has NO surviving bracket. It stays because nothing supports 120 either and
moving a shipped timeline on no evidence is worse. That is a default, not a
derivation, and the entry now says so. `kind` is already `authored`.

2. 41 % OF THE REPO PATHS CITED IN MY OWN docs/port/ PROSE DID NOT RESOLVE.

The Decoder observed that everything they hand me links into docs/re/ files that
live only on their branch, so every link they send dangles from here. I turned it
on myself and it was worse than I expected: 37 of 91, in two classes.

  19  on their topic branch -- real files, not merged. Not errors, and no one in
      this container can fix them; the fix is a merge.
   7  resolve NOWHERE: docs/BLOCKED.md, docs/DECISIONS.md, docs/FORMAT.md,
      port/manifest.json, port/screens/title/*.json. Left behind by the monorepo
      move and the export/ rename. Simply wrong -- a reader following one gets
      nothing, and nothing had ever told anyone.

All 7 fixed. audit-kinds checks citations in authored/; nothing checked the
PROSE, which is where this port explains itself.

New: tools/port/check-citations, wired into check-all with its control. It fails
ONLY on the resolve-nowhere class and reports the peer-branch class, because a
check that went red for a state nobody here can change is the shape the display
guard exists to prevent. The --selftest plants a dangling citation and requires it
caught, AND a real one and requires it passed -- both directions, since a scanner
that flagged everything would also "pass" the first.

Not settled: finding 3 has no surviving cause and 60 now has no surviving
derivation either; the ~1.0-1.2 menu residual; pgloading_loop5's residual; the
allowance still waits on its grep trigger.

94e44b5ba4 port: the additive-capable reference collapses the divergence 6x, measured at the tag
The Decoder taught `ui_layout::blit` the additive blend at
formats-pin-2026-09-01b, on the argument this port made: the comparison was
structurally incapable, and the refutation keeping additive out was
⟨render-vs-capture⟩ -- that renderer disagreeing with itself while it had a stale
keyframe association, no leaf geometry and no rotation.

MEASURED WITHOUT PULLING THEIR BRANCH INTO MINE: a detached worktree at the tag,
sylpheed-cli built there, verify-screen pointed at it through SYLPHEED_CLI. My
branch is untouched and the reference on `main` is unchanged.

Pre-registered: the diffs caused by the gap should collapse, and whatever remains
is a different cause.

  main_menu     7.2580 max 105  ->  1.2068 max 28   6.0x
  main_menu_jp  7.3440 max 108  ->  1.2111 max 31   6.1x
  extras        6.9757 max 113  ->  1.0229 max 28   6.8x
  extras_jp     7.0734 max 115  ->  1.0255 max 30   6.9x
  title         1.0335 max  88  ->  0.5685 max 41   1.8x
  title_jp      4.4944 max 233  ->  2.8225 max 233  1.6x
  build_12/15   0.0772 max  60  ->  0.0463 max 17   1.7x
  build_00/01   0.0676 max  60  ->  0.0366 max  4   DIFFERS -> OK

build_00 and build_01 stop differing entirely, over3 3422 -> 0.

And the twins agree to a third of a percent: main_menu 1.2068 vs main_menu_jp
1.2111 (0.36 %), extras 1.0229 vs extras_jp 1.0255 (0.25 %). Under the name-keyed
map those pairs were 4.1x and 7.8x apart. Nothing was fitted -- they converged
once when the PORT took the decoded field and again now that the REFERENCE draws
the same blend.

The residual is smaller and its causes are the documented ones: title_jp 2.82 is
the --pose=rest sparkle handling, title 0.57 the ptloop sweep phase, both
untouched by any of this. main_menu/extras and twins sit at ~1.0-1.2 max ~28-31,
new and undiagnosed -- additive was the dominant cause, not the only one. And
build_12/15 do NOT return to their pre-change 0.0368, so pgloading_loop5 carries a
small residual of its own beyond the blend. Recorded, not chased.

🔴 THE ALLOWANCE SHOULD NARROW AND HAS NOT, ON PURPOSE. Its justification is gone,
but check-all builds the reference from the WORKSPACE crate and the additive path
is at a tag, not on `main`. Narrowing now would turn check-all red against a
reference that still cannot draw additive -- a wall of failures meaning one thing,
which is the defect the display guard exists to prevent. The trigger is written
into the script so it does not rot: when `grep -q additive
crates/sylpheed-formats/src/ui_layout.rs` succeeds, drop the export-derived clause
and keep the two named legacy rows. The set that should then differ is measured
above.

H5 confirmed from the other side. And a trap worth carrying: the Decoder nearly
reported my H5 claim as a contradiction because `loop5` is not a sprite -- it is
an ELEMENT, pgloading_loop5.rat, resolving to sprite pgloading_ring.t32. Any
census keyed by sprite name will miss it.

Not settled: the ~1.0-1.2 residual on the menus; pgloading_loop5's own residual;
finding 3, where the Decoder is taking the clock origin; and the 8 claims R1 has
re-opened against ⟨render-vs-capture⟩, including BOTH legs of the rest() pair
that this port's settle behaviour rests on.

c01580740e port: my pteff10 counter-example failed, H5 closes as additive, and I broke my own allowance
Three things, and the first is the one worth reading.

 MY COUNTER-EXAMPLE FAILED. I reported pteff10 as a possible counter-example to
the  DECODED blend bit. It is not: the oracle measures it ADDITIVE on main_menu
in all three menu sessions, every frame, entry 5 of blend-bit-vs-oracle.txt.

My premise was a stale COVERAGE TABLE of theirs, sitting upstream of its own
correction. I inferred "their log does not cover this element" from a summary and
called it a contradiction with a capture. The lesson is not that their table was
stale -- it is that I treated a summary as the log, having spent three iterations
insisting that other people quote instruments rather than conclusions.

Their explanation made a prediction, so I checked it rather than accepting it:
if additive and alpha-over nearly coincide on a dim glow, why did my score move
20 %? Diffing the two renders, where pteff10's blend is the only change:

  identical        373 588 px (40.5 %)
  differing > 3    330 794 px (35.9 %)
  MAX difference   32 levels        pixels >= 60:  0

Their explanation holds and my scepticism does not. Nothing moves more than
32/255. What moved the RMSE is AREA.

📌 And that generalises past this row: raw-rmse is AREA-WEIGHTED, so a shallow
change over a third of the frame moves it far more than a deep change over a few
hundred pixels, and the number alone cannot say which you have. 10.88 -> 13.02
reads like a serious regression and is invisible to an eye. Any verify-capture
row that moves should be asked "broad or deep?" first; it costs one histogram.

I did NOT take their suggestion to exclude the element from the metric. The
reason to exclude -- "the metric cannot distinguish these" -- is now measured to
be false; it distinguishes them fine and weights them by area. Excluding would
remove the only signal that would fire if the bit were wrong elsewhere.

 H5 CLOSES, as a side effect. pgloading_loop5 -- the element I had localised all
951 differing pixels to -- carries blend_additive, and ui_layout.rs has no
additive path, so the reference cannot reproduce that draw by construction.
build_00/build_01 agreed only because they never draw it; with the decoded field
they gained loop1/loop4 additive and now differ too, as predicted.

🟢 The strongest corroboration of the decoded field came unfitted, from the rows I
was not looking at. EN/JP twins were 4.1x and 7.8x apart under the name-keyed map
and are now 1.1 % and 1.3 % apart (main_menu 7.26 vs 7.34, extras 6.98 vs 7.07).
A disc-wide field predicts locale twins render identically; a screen-name map
cannot. That prediction was not available to me before the swap.

🔴 AND I BROKE MY OWN ALLOWANCE, silently, one iteration after building it.
check-all's verify-screen allowance derived from authored/rendering.json's
additive_elements -- the key I deleted last commit -- so it evaluated to EMPTY and
would have failed six rows for no reason anyone could read off the output. Caught
by going to look, not by the check. A derived allowance is only as durable as the
thing it derives from, and I pointed this one at a file I then emptied.

It now derives from the EXPORT. ⚠️ That is LOOSER and the cost is stated: 12 of
16 screens qualify and verify-screen goes fully green. Measured after the swap
the two sets line up exactly -- all 10 differing screens have a drawn additive
element, all 6 agreeing screens have none -- but a screen differing for some
OTHER reason would now be excused. 📌 The real fix is not here: verify-screen
compares two renderers and one cannot express a blend the disc declares. Giving
ui_layout.rs an additive path would make it meaningful again. PROPOSED, not done
-- their crate, and their refutation of additive predates the measurement that
overturned it.

Not settled: finding 3, which now has no surviving named cause at all -- the
Decoder is taking the clock origin, on the grounds that every measurement either
of us has made is a DIFFERENCE and a difference cannot detect a common offset.

7c8e4a863a port: adopt the game's 61% stick threshold, and find my verify-screen numbers were llvmpipe-specific
Two things, and both are about a hidden parameter nobody was recording.

1. THE STICK THRESHOLD IS DECODED NOW, and it replaces an authored value.

The Decoder measured that the game digitises the left stick to four direction
bits at 61 % deflection, so it never sees a velocity. Gamepad.ENTER moves
0.5 -> 0.61. The 0.5 was never a chosen value: it was a FLOOR, because Godot's
`ui_*` action deadzone is 0.50 and the latch must not arm below it. Between 0.50
and 0.61 Godot reports a direction the real game does not, and at 0.5 this port
stepped there.

The mechanism also corroborates the human's latch fix rather than merely
agreeing with it: a control that digitises to bits cannot express a rate, so
"one step per deflection" is what the hardware layer CAN produce.

⚠️ The 0.11 hysteresis gap stays AUTHORED -- nothing says the game has
hysteresis at all. And a human chose 0.5, so this changes feel: revert the one
constant if 0.61 reads as needing too much push.

🔴 AND THE CONTROL CAUGHT MY FIRST ATTEMPT AT ASSERTING IT. I added the new
device-level row as subject "latch", and `verify-input --control` failed
immediately with "a check did not invert -- it is not testing what it claims to
test". It was right: removing the latch does not remove the THRESHOLD, the
unlatched path tests `>= Gamepad.ENTER` too, so 0.55 counts 0 either way and the
row could never invert. It is a NEGATIVE, and its positive control is the 0.70
row on the same shape. Reclassified.

That also exposed a smaller thing: ok()'s negative branch HARDCODED "positive
control is the stick row", so a second negative would have borrowed someone
else's green line. It now takes the control's name, defaulting to the original
text so the d-pad row is unchanged.

 I never consumed the pad bit table they have just corrected -- checked by grep
over port/, authored/ and tools/port/, not remembered.

2. MY verify-screen NUMBERS WERE llvmpipe-SPECIFIC, and the prediction failed.

Pre-registered: both renderers blend in encoded 8-bit space, so the diffs should
be identical or within 1 level on the GPU. They are not -- every mean rose 3-35 %:
title 0.4431 -> 0.5936, main_menu 3.9363 -> 4.1449, extras 6.7422 -> 6.9757,
title_jp 2.7715 -> 2.9448, main_menu_jp 0.7885 -> 1.0157, extras_jp 0.6592 ->
0.8906, build_12/15 0.0368 -> 0.0454.

But the MAXIMA are unchanged -- 41, 97, 113, 233, 17 identical, 26 -> 27 on one
row. That is a rounding population growing, not content moving: two rasterisers
round the last bit of a blend differently while the elements that genuinely
differ do not move.

Survives: the additive diagnosis, because it rests on an ORDERING and the
ordering holds (9 elements > 5 > 0); the pgloading_loop5 localisation; the
build_00/01 agreement; the derived allowance, same four failing rows.

Does not, and is now labelled: the histogram (53 % within 1 level, 16 844 over
40); every absolute mean; and the RMSE-vs-capture pair 3151.96 / 3769.61 -- that
ORDERING claim is not re-derived on the GPU and is not claimed until it is.

The rule this earns: a renderer comparison carries its RASTERISER as a hidden
parameter. Nothing here recorded which one produced a diff, and for months there
was only one so it never mattered. Same discipline TEMPORAL-VERIFICATION already
demands for capture rate, applied to what rasterises rather than what clocks.

Not settled: H1's repeat half; H6's +0x04 exposure; the four red verify-screen
rows; whether the port is still nearer the capture than the reference on the GPU.

ba3f490c67 port: P7's gate has an artifact, and the GPU kills my finding-4 candidate outright
Three things this iteration, and the middle one is the human's doing.

P7 -- GATE MET, with an artifact. The path had been wired for some time
(then_video S00A, skipped_chain, after_video -> title, and S00A.ogv in the
export) and NOBODY HAD RUN IT. A milestone is done when its artifact exists, not
when the wiring reads correctly.

Pre-registered: unskipped, S00A is 93.78 s of media, so it should end on its own
at ~94 s and hand off to title. Measured: video ended at 94.13 s -- +0.35 s,
0.4 % -- then -> title, plate raised, script complete at 96.83 s. Both
predictions held. docs/port/p7-gate.md.

And it genuinely decodes, checked because "ends at the right time" does not prove
it: 45 frames in a 2.03 s window, 244 in an 18.91 s one. Scales with the window,
sub-linearly, at the software fill ceiling -- those two runs predate the GPU. The
counts are upper bounds and the port says so itself.

Free corroboration of the fill-rate finding, from a direction it was not designed
for: the unskipped run reports main_menu at 60.3 fps for 94 s, because the screen
never changes during a movie. Same process, same container, same screen: 60.3 fps
with one full-screen video texture on top, 9.7 fps drawing the menu's five
additive full-screen quads.

 THE FINDING-4 FRAME-RATE CANDIDATE IS DEAD, tested rather than argued away.
The human activated a hardware GPU in both containers; Godot takes it with no
change on our side (NVIDIA GTX 1070 Ti, Vulkan 1.4.312, Forward+):

  publisher_logo   17.3-25.0 -> 69.4 fps
  developer_logos  16.7-22.8 -> 69.1
  title            12.7-17.2 -> 61.1
  main_menu              9.7 -> 59.6

Pre-registered that 5-7 full-screen textured quads at 720p is trivial for that
card and the fade would get its full 45 steps. At 69 fps the 45-unit build-in
gets 52 drawn steps and the companion glow's 15-unit rise gets 17 -- MORE frames
than declared units, so every declared alpha is drawn and the quantisation is
absent rather than reduced.

So every candidate for finding 4 is now dead: keyframes vindicated against the
vertex stream, companion quads drawn, blend space matching, settled pose at
0.01 %, no post-process pass, and the frame rate drawing every declared step. The
port has nothing left that is KNOWN to be wrong about the splashes -- which is a
statement about our knowledge, not about the port. The human saw something and
nothing we can measure reproduces it. The next play-test is now the
highest-value thing on this focus, and the rate line will say 60-something.

One figure did not improve: main_menu's worst gap is 117 ms on the GPU against
150 ms on llvmpipe, essentially unchanged while the mean improved 6x. A hitch
that survives a 6x fill speed-up is not fill. Likely first-frame cost, STATED AS
UNTESTED, recorded rather than chased.

check-all now asserts the display before any Godot step. Xvfb does not survive a
container restart and LEAVES ITS SOCKET BEHIND, so Godot reports "X11 Display is
not available", falls back to Wayland, fails that too, and exits non-zero -- and
every Godot-backed step would have gone red for that one reason. Cost me one run
before I noticed. Checked with xdpyinfo rather than by looking for the socket,
because the stale socket is what makes it confusing.

Also recorded from the P7 run, neither chased: Godot reports 4 leaked ObjectDB
instances at exit on that path, and the menu bed keeps playing under the movie
(already an open ask -- does the menu music duck?).

Not settled: the 117 ms menu hitch; H6's +0x04 exposure; H1 (with the Decoder);
the four red verify-screen rows; and what the human actually saw.

26cf6ecac5 port: H3 closes with every named cause dead, and the verify-screen rows are ADDITIVE, not gamma
Three answers landed from the Decoder in one iteration and two of them refuted
things -- one theirs, one mine.

H3 -- CLOSED, and deliberately not closed green. The rate is measured at 56.8
units per guest second (control 1.15 %, two elements agreeing at one clock).
30 and 120 are both excluded. At 56.8 the plate's t=236 lands at 4.15 s against
this port's 3.93 s, so the port is fractionally EARLY. With rest.t, the clock
origin and the anchor already eliminated, ALL FOUR named causes are now dead and
the human's observation is unattributed. Written down that way rather than
letting H3 go quiet: the strongest remaining candidate is that A was unbound on
the play-test build, so that human could not skip the 137 s intro, and the run
they judged is not the run any of these measurements describes.

`units = 2 x frames` is dead as a route -- the same animation takes 21 labels in
one capture and 33 in another. Audited: this port never used it. boot.gd
integrates `delta * units_per_second`, so the retirement cost authored/timing.json
a JUSTIFICATION and not a behaviour, and I have recorded which leg died and
which survived. The surviving leg has no frames in the chain: 12 declared units
against a 0.14-0.30 s measured black plateau = 40-86 units/s, which excludes 120
on its own. 60 is KEPT -- 56.8 is 5.6 % away against ~5 % quantisation.

H4 -- ANSWERED, and MY PREMISE WAS WRONG. I reported the verify-screen rows as a
blend-SPACE divergence. The transfer curve I built for that was a mean per
reference-value bucket over a BIMODAL population -- 53 % of pixels within 1 level
and 16 844 differing by 40+ -- and the gamma shape was an artefact of the
binning. A mean over a mixed population is not a transfer function.

All three renderers blend in the encoded space:
  game       k_8_8_8_8 on 2402/2402 and 33779/33791 draws, _GAMMA zero times
  Godot      measured with a pre-registered control -- alphas 64/128/192 render
             64/128/192 exactly; linear-then-re-encode excluded by 33-74 levels
  reference  integer math straight on 8-bit values, no linearisation

The real cause is ADDITIVE. The port draws 5 elements additive on main_menu and
9 on extras, transcribed from the Decoder's per-draw RB_BLENDCONTROL0 log off the
running game; ui_layout.rs has exactly two blend sites, both alpha-over, and line
1169 records that it tried additive and refuted it from its own composite
metrics. The two renderers disagree on purpose, and the disagreement tracks the
set size: 9 -> 6.74, 5 -> 3.94, 0 -> ~0.7. That ordering was not fitted; the
additive map predates this comparison.

check-all: the allowance is now DERIVED from authored/rendering.json's additive
set plus the two legacy rows, instead of a literal list. A screen is excused
BECAUSE it has additive elements the reference cannot draw; one that differs
without them still fails, which a list could not express. Verified against the
last run's set: main_menu and extras pass, main_menu_jp, extras_jp, build_12 and
build_15 still FAIL. check-all stays red on those four and they are H5 -- not
diagnosed, not excused. build_12 and build_15 report byte-identical statistics,
which points at one shared element rather than two coincidences.

Refutation attempts: the hit this iteration is against my own page again -- the
blend-space diagnosis, killed by a control I ran on my own renderer. The
Decoder's encoded-space finding and their 56.8 both survived the only checks I
could make: my control reproduces their space independently, and their rate is
consistent with authored/timing.json's frame-free leg.

Not settled: H5's four rows; whether the splashes tick at the title's rate (they
are a different GamePart); H1 (key repeat); what the human actually saw.

da7864e499 port: both of my H3 conclusions were wrong, and check-all stays red on a sixth-screen divergence
The Decoder answered H3 in both halves (a482d9a, against a pre-registration
committed before they read the capture) and refuted two things I published an
hour earlier. Both are struck in place, not deleted.

1. units/frame is 2, not the 5 I inferred. Three consecutive gap-free steps of
   exactly 23 on ptbtn00's own ramp; 255*2/22 = 23.18. My 4.4-frame prediction
   is excluded by more than 2x.

   My derivation was sound arithmetic on two unsound premises, both mine to
   have used:
     - an alpha step is not a clock rate. dA/frame = 255*(units/frame)/T, so
       elements with different declared T show different steps at ONE clock.
       Splash quads step 34 with T=15; the plate steps 23 with T=22.
     - my "onsets" were first submissions, and on splash A both quads are
       already at a=85 when first submitted -- biased late, and by a different
       amount per element because the bias scales with T.
   The three intervals agreed with each other because they SHARED the bias.
   Three measurements with a common error are one measurement. That is the
   shape I should have checked for and did not.

2. My claim that the t=160 anchor collapses `clock: "shared"` is WITHDRAWN. The
   anchor is indeed t=160 -- ptcopyright, calibrating to t~168-176 -- but I
   falsified the model using the 2.135 s figure, which is the one number the
   same capture puts in dispute. Falsifying a model with the quantity that is
   itself under dispute is the error. Against the new capture's own labels the
   declared 54 and 76 units reconstruct at 44 and 66 -- short by 13-19 % in the
   same direction, with empty labels a named candidate for the residual.
   `clock: "shared"` stands, and the port keeps it.

Still open and now the only thing left on H3: units/second = 2 x guest fps, and
whether the guest is 30 Hz or 60 Hz is unestablished. 2x60 = 120 units/s puts
the plate at 1.97 s instead of 3.93 s, which is the size of what the human
reported. The Decoder asked me not to move off 60 on their account yet; I have
not.

Separately -- check-all is RED and stays red. verify-screen newly DIFFERS on six
screens outside its allowed set (main_menu, extras, main_menu_jp, extras_jp,
build_12, build_15). Measured, not diagnosed:

  * not this iteration's doing, and excluded structurally rather than by a
    passing test: sprites are read as bytes and built with
    Image.load_png_from_buffer, so they never enter Godot's import pipeline and
    the new `--import` step has no path to the drawn pixels;
  * the difference is FULL-FRAME, exactly zero on unblended pixels (18 081 of
    them agree to a hundredth of a level at ref 199/204/255) and gamma-shaped on
    every blended one. That is a blend-SPACE divergence, not moved content;
  * scored against live-main-menu.png the port is 16 % closer than the reference
    (RMSE 3152 vs 3770) -- an ordering only, since both sides carry this
    script's --pose=rest contamination, which has produced a false finding here
    before.

Not widened. This allowance has twice been broadened with a reason that turned
out false, and "I measured it but cannot say which renderer is right" is not a
reason. New ask H4: what colour SPACE is the blend evaluated in -- the Decoder
has the equation from shader ucode, not the space.

Refutation attempts: both of this iteration's hits are against my own page from
last iteration. The Decoder's units/frame law and their anchor measurement both
survived the only check I could make of them -- their steps reproduce this
export's declared T on two screens at one clock.

Not settled: guest fps; which renderer's blend space is right; H1 (key repeat).

6eccfa84d8 port: the plate's lateness is the unit, not our clock -- and the splash blur is an asset we already draw
H3, the PRESS (A) plate. Established which half it is, as the brief asked, and
the answer moved once during the iteration -- both readings are recorded because
the first one was confident and wrong.

Eliminated, ours:

  rest.t      not in the causal path. The plate's ARRIVAL is a declared keyframe
              (transparent to t=214, opaque at t=236); rest.t=236 only picks
              where `holding` parks it, and 236 is that ramp's own peak.
  clock origin  the two builds share one clock exactly -- 85 of 85 filmed title
              frames have view_units == overlay_units to 3 dp.

NOT eliminated, the Decoder's: the unit->seconds constant. I first ruled it out
"by sign" using the emulator's 28.1 fps presentation rate. That conflates a
wall-clock conversion with units-per-game-frame; the correction is written down
rather than edited away. The Decoder's splash draw capture (3cc1b51) then gave
an independent handle on it, from a screen with nothing to do with the plate:
three intervals of the publisher splash all read 5 units per guest frame against
the declared 2. At 30 fps the plate would land at 1.57 s rather than 3.93 s --
this port ~2.4 s late, the right magnitude for what the human saw. It collides
with title-plate-delay-measured.md (~55 units/s) by a factor of 2.7. Both are
oracle measurements; asked in BLOCKED.md H3, not picked between.

Finding 4, the splash blur. The Decoder found no post-process pass; the human
says the logos go blurred -> sharp in about a second. Those resolve each other:
every logo ships a pre-blurred copy ~21x20 px larger and concentric, drawn alone
first and crossfaded out as the sharp logo fades in.

  🔴 So "the port applies no blur at all" -- in BLOCKED.md H2 and in the
  play-test -- is FALSE, and it came from our side. The port draws all seven
  quads of the developer splash, companions included, and always has. Shown by a
  frozen sweep 3 units a step: companions alone at u=3..15, all seven at
  u=18..42, sharp only from u=45.

The instrument had to be fixed before any of this counted. `--film` scheduled
frame n for n*interval and reported nothing; one 1280x720 save_png costs ~0.24 s
under llvmpipe, so a request for 0.05 s delivered 247 frames in 60 s where 1200
were asked for -- an achieved 4.1 fps against a requested 20 -- and the deficit
accumulated silently into the frame index. It now writes <film>_frames.tsv with
the second each frame was ACTUALLY taken at, and prints achieved against
requested. The schedule is deliberately not rebased onto _elapsed: catching up
would hide the shortfall.

check-all now reimports the Godot project first. `port/.godot/` is gitignored, so
merging a commit that adds a `class_name` leaves a stale class cache and the
whole project fails to parse -- which is exactly what merging the human's
gamepad.gd did in this container.

Refutation attempts, four:
  survived  the title's settle window [160, 236] -- our exporter still computes
            [160, 236, 198] under the corrected record layout
  survived  the Decoder's Q0/Q7 quad mapping -- this export's declared rects
            reproduce the guest's vertex stream to ~2 px and ~4 px
  refuted   "ptlogo1 rests at t=251 and stops moving at t=42" -- rest.t is now
            42. The record-layout fix repaired the very element that was the
            headline evidence for rest.t != settle. The conclusion survives on
            other elements; the example does not
  refuted   ours: "ptbtn00 reaches a=255 at t=238" (it is 236, so 118 units not
            120) and "pteff00 is 7 % opaque at 243" (it is 0 %; that quad clears
            by t=16 and 261..269 is the fade-OUT, not a fade-in)

Not settled: which of the two oracle rates is right; whether the t=118 or the
t=160 anchor is what the glyph counter saw; whether the game holds the blurred
companion longer than we do.

b70b638cb4 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.

d45b23ebbe 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.

05be7d19f7 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.

b6a4a079f9 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.

6af06bd595 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.

f4351b0b8c 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.

5738b8328f 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.

6cdffd8f77 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.

98d02e7c24 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.

6f8211a560 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%.

21645dfe6f 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.

2db0267b3d 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.

2759f3e719 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.

d768c3ef75 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.

19987daafe 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.

9f321e6213 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.

43ee16ab43 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.

601dba3d0b 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.

9c4d04a203 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.

b4cac06ac2 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.

4e82245f24 port: close the last control harness, and two authored values checked against bytes
verify-transcode-fidelity --selftest closes my list. It had three controls running
every time -- identity, a 4-pole top-end loss, an unrelated movie -- and none
asked whether the measurement itself was live. With an empty band list every
comparison reads 0.0 dB: identity passes, the real pair passes, and only the
unrelated-movie control fails, reporting exit 1 for a broken instrument. Same
shape as the empty register in check-claims, same fix: exit 2. The self-test
drives the script as a subprocess over a short window -- normal 0, bands emptied
2. All four tools now assert their own harnesses.

Top-item sweep from the DIFFICULTY finding: one site, MenuFlow.initial_focus's
buttons[0], already documented as a repair. Every other [0] in the tree is
unrelated indexing. Nothing to fix, recorded so the sweep is known to have run.

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.

d1a1633619 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

4fff1beecd 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.

75be660fb4 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.

hole and sent it to the Decoder, who wrote back that it was the part of my message

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.

aedcd35eef 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.

82e3755bb7 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.

ec2a17eaa9 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.

01b0c9b10d 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.
