b7c2e9b2de port: apply the measured positional weights, keyed by byte size
ADV's three chunks map onto the Decoder's contexts exactly, each a declared
byte_size plus the 60-byte RIFF header. authored/audio.json gains
voice.stream_weights keyed by SIZE, and the exporter weights only when every kept
stream matches, falling back to the divisor otherwise.

The key is the check: two weeks ago these same sizes did not fit the region the
resolver returned, which is how the 238-packet late start was found. Applied
positionally the weights would have gone onto the wrong streams silently. S00A
matches nothing and keeps the divisor. ADV mixes at 0.4142/0.2929/0.2929, -2.87.

Unlooked-for confirmation: the filter folds chunks 0 and 2 from two live channels
and chunk 1 from one, found independently by live_channels, matching their claim
that ctx1 is the only stream with a silent channel.

Also files an UNEXPLAINED regression: verify-menu-audio's dead-press check now
reports DIFFER across three runs, diverging at 0.085 s with different durations.
Not diagnosed, not the voice change, and left failing rather than silenced. The
check's premise is cross-run bit-determinism, which is what made it strong and
also what makes it brittle.

e2d889bf97 port: voice export carries every qualifying stream; a unity sum was refused by check
#4 answered: ADV.wmv carries ONE audio stream and it is WMA Pro 5.1, not XMA, so
the movie's own track is the bed and the three streams are additional. Solving
capture = 0.600 x movie + residual gives three residual signals at three
positions, with LFE reproducing to -115.73 dBFS -- where nothing is added the
decoders agree exactly, so the rest is added content.

presentation: all keeps every equal-length non-silent survivor -- ADV 2 of 3,
S00A 1 of 3 -- and the warning now keys on kept < present rather than on more
than one existing.

A unity sum was tried first and check refused it at +2.62 dBFS. The BGM stems
precedent did not transfer: those are stems of one signal, these are positions in
a field whose downmix weights sum to one whatever the assignment. Dividing by the
count preserves the total and claims nothing about placement; ADV lands at -3.1.

That is the OPPOSITE of the two divisor bugs already in this file, where a silent
input sat in the divisor. Divide-by-N is not right or wrong in itself.

Also carries their census correction: the ALSA permutation does not apply, the
map is the identity, and the '82% silent' channel was LFE.

9064c0f9cb port: rendered pulse counted in their units; #4 refutes the voice value without fixing it
With their predicate the port's render is comparable to their capture for the
first time: pulse minimum 805 against their 714, peak 1420 against 1520, both far
above the 154 floor. So 'never goes off' holds in the port's own render.

My pulse is 24% shallower and I am NOT tuning it -- their own limit says the
counter is thresholded pixels, so a depth measured this way is a fact about the
threshold as much as the glow. The port draws the declared ramp.

#4: 148 s of the game's output, five of six channels distinct, no channel a copy,
largest pairwise correlation 0.70 between FL and FR. So presentation: loudest --
keeping one stream -- is refuted by what the game PLAYS, not merely suspected.

Stays unfixed on their instruction: the stream-to-channel mapping is not run, and
swapping one authored guess for another is worse than a guess that is labelled.
Also records that '6 channels' is Xenia's hardcoded default, not evidence of 5.1.

8adae30d1a port: the plate pulses -- restore the looping record, over the base rather than instead of it
Ask #1 measured: held at the title with no input the plate oscillates ~23 cycles
per window with no decay and NEVER goes off -- floor 159 thresholded pixels,
pulse bottoming at 714. A glow alone cannot do that (0 -> 80 -> 0); a steady base
plus a pulsing glow can, and 714/1520 are base-only and base-plus-glow.

The port already had the base right: ptbtn00's fade to 0 at t=244 is its EXIT
ramp, and while held the base sits at alpha 255. The glow was missing.

The defect was in the renderer, not the entry I deleted on 2026-08-29. _draw
treated a looping record like a focused one -- drawn INSTEAD of the base, which
is right for a focused button and wrong here. I deleted the right thing for the
wrong reason. A looping record now draws OVER the base and the entry is restored.

Rendered: 95.68 base only, 115.52 at peak, period 1.980 s against a declared 120
units = 2.000 s, ratio 0.990. Visible on the boot path; not under --screen
--overlay, where a static overlay poses at its arrival by design.

Authored in UNITS on their instruction, with their three limits verbatim: one
boot, does not distinguish boot from attract title, and 714/1520 is not an alpha
ratio so no duty cycle is inferred.

f06be84be6 port: a withholding reason was false -- the hidden leaf is a visible expanding ring
authored/rendering.json justified not drawing build_12,15/pgloading_loop5 with
'leaf scale (0,0)'. That describes t=0 and t=30 and nothing after. The leaf holds
pgloading_ring, scale ramping 0 -> 250 -> 800 -> 1000 with alpha full at t=55 --
an expanding fading ring, visible at scale 140 alpha 143 at the port's own pose
instant near t=44. Withholding it declines to draw SOMETHING.

Still withheld, on the reason already in the file: no oracle capture for a
loading screen and verify-screen's reference draws no leaves, so the content is
unadjudicable. Behaviour unchanged at 59530 px.

The two entries in that list were written to different standards -- ptlogo_eff2
gets four paragraphs working through both readings, pgloading_loop5 got one false
line. The difference is that one was interesting and one was a loading screen.

Also verifies the measurement in the same paragraph: 'max went 155 -> 232 when
drawn' reproduces at 231, differing pixels 20498 -> 58313. The file's numbers
were sound and its reasoning was not, in adjacent sentences.

a758f9b247 port: --focus was ignored on the menu path; focus rendering now verified against the oracle
live-main-menu-options-focused.png -- the only capture of a known focus state --
was untestable because --focus= parsed, was stored, and was overwritten by the
authored initial focus on every _menu_enter. Every run logged focus ptbtn01
whatever was asked for. Now pushed into the menu model so navigation continues
from where it was forced.

With it working, each capture picks out exactly one button: ptbtn04 at 0.1355%
against 0.70-0.82% for the others on the OPTIONS capture, and ptbtn01 at 0.0705%
against 0.72-0.84% on the plain one. 5x and 10x discrimination. First time the
port's focus rendering has been checked against the game at all -- the existing
main_menu row uses an authored focus and could never have caught a focus error.

Records in flow.json that live-main-menu.png shows NEW GAME focused, so the
authored initial_focus matches the one frame it can be checked against -- and
that this does NOT overturn Q5's measured instability. It stays authored.

Adds main_menu_options to verify-capture at 0.13%.

3c71962698 port: the PRESS (A) plate could not be drawn at any instant -- four faults, and a misquoted number
1. --time= was silently ignored on any screen with a settle window >= 30 units:
   pose_at overwrote the requested instant with settle_instant. ScreenView.frozen
   now marks an explicit instant and skips both clamps.

2. press_start's settle window was [0,214] -- the dead stretch BEFORE the plate
   exists -- so its settle instant was t=107, where the element is alpha 0. The
   exporter now rejects intervals in which nothing is visible. title keeps
   [160,236], the interval the Decoder's draw stream confirmed.

3. My authored looping_focus_records entry for press_start/ptbtn00 drew a dim
   focus record INSTEAD of the plate's own sprite: max 0 vs max 252.5. Deleted --
   an authored guess that overrides a decode with a worse answer is removed.

4. verify-capture passed --time=5.9617 for the title and it was never applied.
   Every title figure it has printed, including the 0.26% quoted to the Decoder,
   was measured at the settle instant under a note claiming t=357.7. Both rows now
   pose by omission and the note matches. title is 0.21% honestly; splashes
   unchanged at 0.01%.

The boot's end artifact now contains the plate (region mean 95.7 vs 33.6).
Corrects last iteration's BLOCKED row, which had the entry's effect backwards.

fce921d5c9 port: add wait:<seconds>, observe the bed's loop, and measure the seam at 3.4 s of silence
The port could not be asked to run for a stated duration -- a bare  step
is a no-op that returns at settle -- so nothing after the settle point was
observable. An 87.7 s bed on a harness whose longest menu run was 7 s.

The bed loops at 87.8 s against the track's 87.7 (r=0.947 and 0.885 on a clean
bed-only recording): loop: restart behaves exactly as authored. First
end-to-end observation of P6 looping.

The authored 'audibly wrong at the seam' is confirmed and quantified: 36
consecutive near-silent 50 ms windows, 84.40-87.80 s, about 3.4 s of silence
after a fade from RMS 2057 to 431. Recorded in authored/audio.json. It does NOT
license trimming, which would still invent a loop point.

My first wait: used create_timer and ran 39% long (30 s requested, 41.7 s wall)
because an idle scene throttles the delta it counts down on. Now polls
Time.get_ticks_msec: +4.6%. Checked before generalising: over a boot the port's
clock tracks wall clock within 4%, so animation timing is sound and the earlier
splash-dwell agreement stands.

7844bf5681 port: audit what rests on a single draw-stream run; black_hold_units=9 sits at the top of its range
Their ARM=early disclosure (~40% silent trigger loss) makes every draw-stream
figure n=1. Exactly one port constant depends on one: the black hold. Three of
its supports have moved -- the 105-frame count they revised to 114, the 2.231
corroboration they retracted, and a run-average rate now known to drift 33%.

Redone on their corrected segments the two runs give 8.95 and 6.71 units, not
one number: overlapping +/-1 error bars are not agreeing central values when one
frame is a third of the quantity. Range ~6.5-9.2, port at the top.

Value UNCHANGED and proposed rather than adopted -- it would be my arithmetic on
their instrument. Filed with the single run that would settle it.

Also checks their statistics: per-boot excesses reproduce exactly, and their
2.3 sigma uses population SD where sample SD gives 1.89 -- cutting against their
own concession. Neither framing reaches significance.

011ba1065a port: their corrected calibration matches the file at all six points; guard the 60 against emulator drift
Counting indices/4 lands every transition where the export's declared alpha>0
count changes, within a half-open boundary. Their quad counts (1/2 publisher,
3/6 developer) also reproduce exactly when restricted to sprite-bearing
elements -- independently confirming the layerless backdrop is absent from the
batch they log.

Refutation: their drift explains the corpus 4.1% in SIGN but overshoots in
magnitude 2.4x (predicts a 1.369 ratio, corpus shows 1.278, declared 1.214).
The drift was measured in their container and the 4.1% belongs to a different
instrument -- the same transfer I just got wrong with build 4.

Guards keyframe_units_per_second at the constant itself: 60 is the game's
logical rate, not a frame rate, and the 33% drift is not evidence about it.

be643ba58a port: withdraw 'the boot is known too fast' -- the splash dwells are declared and the port already played them
The Decoder measured both splashes over 3 cold boots: publisher t=0..255,
developer t=0..210, the developer agreeing with wall clock to 1.1%. The port
emits each declared value plus the 9-unit black hold, exactly. No code change.

My error was the generalisation, not the arithmetic: build 4 is the title, whose
exit is caused from outside its timeline, so it holds; a splash's exit is caused
by nothing, so it plays out. I used the one boot screen the port is unaffected
by to overturn the two it governs. Declining to scale by 9x while adopting the
conclusion that implied was half a caution.

Also refutes their two splash boundaries as not comparably anchored: 2.237 vs
2.414 units/frame in one boot, and the publisher has a glow symmetric with the
developer's three.

b366e404ee port: the clock freezes at settle -- my window is the game's, and the boot is known too fast
The Decoder measured build 4's top-level clock stopping inside [160,236]. The
exporter computes title's settle window as [160,236,198] from the file alone.
Same interval, two independent methods -- the first evidence for the settle
instant that does not come from our own renderer. ptcopyright reaching alpha
255 exactly at t=160 agrees from a third direction.

Corrects a claim in three places: timing.json, flow.json and boot.gd all said a
screen's dwell IS its keyframe group and the port reproduced 'the disc's own
pacing'. Build 4 declares ~120 presented frames and dwelled ~1100. The decision
to hold zero extra stands; the claim that it was faithful does not.

Checks their two declared spans against the file: both exact, with a 106-vs-105
interval-convention quibble that changes nothing.

39209eab05 port: the title's sweeps loop, the black hold is 9 units, and one claim refuted
THREE THINGS FROM THE DECODER, one of which I am not taking.

REFUTED: "the developer splash is one composited quad, the bounding box of the
three logos". The observed quad is 525x259 at (378,155). The three logos'
bounding box is 500x421 at (390,164) -- a 259-tall quad CANNOT contain them, and
palogo_anima alone starts at y=449, thirty-five pixels below that quad's bottom
edge. The observed quad matches the union of gamearts_eff and seta_eff, 521x261
at (379,154), to about four pixels in every dimension -- and both of those are
TRANSIENTS my own census flagged, dark by t=45, so a frame containing that quad
is a build-in frame rather than the settled screen. I cannot see their draw
stream, so I sent the arithmetic rather than a verdict, and the port keeps
drawing three: I will not stop drawing an element on a claim whose stated
identification excludes that element from its own bounding box.

THE BLACK HOLD IS 9 UNITS, NOT 12. I authored 12 from Q7's luminance plateau of
0.17-0.23 s, supported by the menus' transition quad. The Decoder counted
SUBMITTED QUADS instead -- luminance cannot separate the outgoing fade's tail
from true black. Four frames with no sprite quad at all, at 2.284 units/frame
derived from the disc as its own clock, gives 9.1 units = 0.152 s (6.9-11.4).
That overlaps the luminance figure only at the top, and the true black is SHORTER
still since both boundary frames carry picture. My 12 was supported by analogy --
a different screen's quad on a different path -- and a number that fits by
analogy loses to one measured in place. verify-dwell's bound moved with it; both
screens still agree.

THE TITLE'S SWEEPS LOOP. The oracle shows the quad oscillating over its whole x
range and resetting hard, one reset in the first title dwell and two in the
second. The loop-length field could NOT have settled it, correcting a hope I had
stated: both records declare exactly their last keyframe time, slack zero, and
"loops at 600" and "runs once for 600 and stops" write the identical header.
Verified on the two sweeps' LCM, since their periods differ: 600 and 720 realign
at 3600 units, mean diff 0, against 0.438 at half that.

Scoped to the title. The menus declare the same lengths but the oracle
measurement is of the title, and my own weak evidence points the other way there
-- best match with the sweeps off-screen, three times worse mid-screen, against a
73% on-screen duty cycle if they looped. Two weak signals in opposite directions
is a reason to scope, not to pick.

6c78b3cda9 port: the publisher residual was a missing black hold -- we had both dismissed it
I carried this as "0.03 s outside a composite bound, probably a property of the
bound rather than the game", and the Decoder agreed. Both wrong, and the way it
was settled is the point: I stopped reasoning about the bound and filmed the
transition.

At 0.05 s the port fell straight out of the publisher's fade into the developer
logos -- mean 5.06 -> 0.32 at t=4.20, then 5.65 at t=4.25. NO BLACK FRAME AT ALL,
where the oracle measures a 0.17-0.23 s pure-black plateau (HANDOFF Q7). The
bound was fine; the port was missing a fifth of a second of black, and had been
since P3.

Authored at 12 units because the boot path has nothing to read it from:
publisher_logo and developer_logos each carry a single palogo_eff0, a 1280x720
primitive with ONE keyframe at t=0 -- static, not a transition ramp. The menus'
quad declares black for 12 units and 12/60 = 0.200 s sits mid-range, so the
number is the disc's where a screen has one.

Filmed after: t=4.25, 4.30, 4.35, 4.40 all at mean 0, then the developer logos at
4.45. publisher interval 4.26 DIFFERS -> 4.47 agrees; developer 3.62 -> 3.73,
still agrees. Settled-frame comparisons untouched, as they should be.

THE LESSON IS THE SHAPE OF THE DISMISSAL, NOT THE NUMBER. "A 0.03 s miss against
a bound composed from two measured ranges plus jitter slack is more likely a
property of the bound" is plausible, was accepted by both of us, and was wrong.
The composite bound is why the miss looked small -- the underlying gap was 0.2 s
-- and a plausible explanation for a small number is how a real defect stays
hidden. The film cost one command.

Also recorded: the Decoder has reproduced across two build-ins that the console
NEVER draws ptlogo_back2eff3 (0 draws against ~5 expected), with sampling phase,
invisible draws and position error all ruled out -- but WHY is not established,
and nothing in eff3's record differs from its neighbours. The port keeps drawing
it, deliberately: dropping an element the disc declares on a measurement with no
mechanism is authoring a behaviour neither agent can derive, and nothing this
port gates on would notice, since the flashes live only in the build-in and
verify-capture compares the settled frame.

4031a9c58d port: the plate's period is 120, decoded -- and 105 was falsified with my own ring number
The Decoder found it in the format: a nested record is itself a RATC bundle and
its header's +0x08 is the LOOP LENGTH. A record's keyframes need not fill it and
the slack is a hold at the final pose, so ptbtn00f is 105 units of ramp inside a
120-unit cycle -- the glow rests dark for 15 units. The five ptbtn0Nf records
fill their 120 exactly, which shows the slack belongs to that record and not to
the format. Disc-wide over 1781 timed nested records: 92.3% declare exactly their
last keyframe time, 7.7% more, 0 LESS -- the falsifier never fires.

THE DECISIVE TEST USED THIS PORT'S NUMBER. Both candidates need the same emulator
pacing factor, and the ring measures it independently: declared 120 -> 2.177 s ->
1.0885. 105 units needs 1.211-1.337 to reach the measured 2.12-2.34 s, which
EXCLUDES it; 120 units needs 1.060-1.170, which CONTAINS it. Two different
elements in different bundles, separate runs, tied only by both declaring 120.

My three readings in order are the useful record: 129 (105 + the since-deleted
exit_ramp_units) fitted the measurement for a reason that evaporated; 105 (the
group length) I shipped knowing it was 17% short; 120 is decoded. And the
123-vs-129 pair I once called unseparable STRADDLED the right answer without
containing it -- the sharpest argument I have seen against treating "two
candidates, nothing separates them" as if the truth must be one of the two.

Verified bit-identical 120 units apart (mean 0), 0.061 at a quarter, 0.888 at
half. Still authored because the pinned tag does not expose +0x08; delete the
entry the day a tag does.

THEIR rest() FLAG, CHECKED RATHER THAN ASSUMED: they warned a focus record is the
kind of element rest() mishandles. Censused -- 34 focus-record elements, only 2
with a varying alpha, both ptbtn00f, whose rest.alpha of 80 IS their peak,
exactly the pathology described. The port does not hit it because the plate draws
through the loop path, and the other 32 are constant-alpha so rest() is safe.

d57366a35f port: the focus ring had silently stopped, and the plate's period is now the disc's
BLOCKED said the record-layout change touches five things: pose_at,
settle_units, spin_period_units, exit_ramp_units and the plate. I checked two,
reported that, and did not work the rest of the list.

`spin_period_units` required "the first timed and the second untimed". Under the
corrected layout the ring reads t=0 rot=0 and t=120 rot=360 -- both timed -- so
the rule returned 0 and THE FOCUS RING STOPPED SPINNING. Nothing reported it: a
period of 0 is a legal "this element does not spin".

Rewritten to take the SPAN between the two poses: 120 - 0 = 120 units, the same
number the old rule produced, which is evidence the corrected layout is
self-consistent rather than merely different. Verified the way P5 verified it,
by bit-identity one period apart on the ring's own 60x60 box so the ptloop sweeps
cannot confound it: 0 at +120 units (twice), 8.61 at a quarter period, 8.88 at
half.

Three wrong instruments on the way, and the sequence is the lesson. A whole-frame
`max` saturates on one rotating edge (adjacent frames scored 131 with a mean of
0.022). A live --menu filmstrip jitters by up to a frame, which is ~3 degrees of
ring. And a whole-frame comparison is dominated by the sweeps, which move 480 px
over one ring period. `--focus=<id>` was added so a --screen run can draw a focus
record deterministically, which is what made the check reproducible.

THE PLATE'S PERIOD IS NOW 105, THE DISC'S OWN GROUP LENGTH, and it disagrees with
the measurement. The ambiguity the entry carried is gone -- it used to say the
cycle might restart at t=6 rather than 0 and that nothing separated them; the
group now runs t=0 to t=105, both at alpha 0, and there is one reading. But 105
units is 1.750 s, or 1.906 s scaled by the factor the ring shows between its
declared 120 and its measured 2.177 s -- about 17% below all four corpus timings
(2.12 / 2.19 / 2.34 / 2.31). The old 129 gave 2.34 s, at the top of the range,
which is why it looked right.

129 was the last timed keyframe plus exit_ramp_units, and that constant is
deleted. A period built on a constant that no longer exists cannot stay even
though it fitted better, so the port ships the disc's number and says it is
wrong. Verified bit-identical 105 units apart, 0.83 at 30 units.

5dbc9aeac0 port: delete exit_ramp_units, invert the format's own rule, and guard a scale-0 leaf
FOUR THINGS, and the first is what MISSION section 3 calls the measure of
progress.

DELETED `exit_ramp_units` AND `exit_ramp_seconds`. They were authored because the
disc had no time slot on a group's final keyframe, so the ramp into it was the
one unknown duration per screen. Under the corrected record layout that keyframe
does not exist -- a group is an 8-byte header then frames x {u32 time; 36-byte
pose} and every pose is timed. VERIFIED DEAD BEFORE DELETING: setting it to 9999
(166 s) moved the boot's transitions by 0.04 s, which is wall-clock jitter, and
both uses in ScreenView are gated on a condition that no longer fires on any of
the export's 866 keyframes.

INVERTED THE FORMAT'S OWN RULE. `check.rs` enforced "the final keyframe has no
`t`; the disc has no time slot there" and FORMAT.md stated it. Both are now
backwards, and the validator fired 150 times on a re-export. I had not run
`check` between pinning the tag and measuring against the oracle -- the pixel
harness was green while the format validator was failing on every screen with a
multi-keyframe group. A correctness harness does not replace a format one; they
fail at different layers.

GUARDED A SCALE-0 LEAF, which the Decoder hit in its own renderer: its leaf
branch marked the element drawn unconditionally while the blit returned early on
zero scale, so a scale-0 leaf suppressed its parent and blanked the element --
live on all four loading screens. This port did not have the bug only because
authored/rendering.json happens not to list pgloading_loop5. That is an accident
of a gate written for another reason, not a defence, so `_draw_leaf` now reports
whether it drew and `_draw` falls back to the parent.

ISOLATED THE PACING QUESTION rather than leaving it as a suspected regression.
Legacy association: publisher 4.70 agrees, developer 3.92 DIFFERS. Corrected:
publisher 4.26 DIFFERS, developer 3.62 agrees. Both misses are ~0.03 s outside a
composite bound. The association traded which screen is marginally out; it did
not regress the pacing.

Bumped the pin c -> d for the parser and audio changes. Its headline renderer
change does not reach this port: sylpheed-cli builds from the workspace crate.

8994ca7c59 port: the 11.5 px was the fit's resolution -- and the lesson inverts
The Decoder closed it by ADDING OBSERVABLES, not by tuning. The vertex buffer
carries positions and colours at the same instant, so all four quantities must
agree on one t: quad A x solves to 357.88 and quad B x to 357.58, both +/-0.12
units, against 355.75 +/-1.54 and 354.09 +/-1.89 from the alphas. Alpha moves
only 0.27-0.33 levels per unit, so one byte of quantisation is worth 1.5-1.9
units -- 6-8 px of sweep at 4 px/unit. That is the whole of the 11.5 px. At
t=357.7 the centres land within 0.70 px and both alphas inside one level.

THE LESSON IS THE EARLIER ONE INVERTED AND IT IS THE HALF WORTH KEEPING.
Checking a wrong rule against alpha made it look confirmed; here the same
insensitivity MANUFACTURED a residual that did not exist. An insensitive quantity
does not merely fail to falsify -- it invents error. Solve on the fastest-moving
field, check the slow one, never the reverse. I was already looking for a pivot
rule to explain 11.5 px when they wrote; there was nothing to find.

REFUTATION ATTEMPT, survived with a nuance: they state the leaf pivot is (200,90)
on a 399x180 sprite, "the pivot is the centre, so rotation displaces it by
nothing". Checked against my export -- pivot [200,90], sprite 399x180, true
centre 199.5,90. It survives, but the sprite is ODD-WIDTH so the pivot is the
centre to within half a pixel rather than exactly. No consequence against their
0.70 px agreement; worth stating because "displaces it by nothing" is the kind of
sentence that later gets leaned on for a sub-pixel claim.

verify-capture now poses the title at t=357.7 rather than 355: RMSE 21.07 ->
20.92, differing 1.82% -> 1.81%. Marginal, and it is the right pose for a stated
reason rather than a better number.

AND ptlogo_eff2 IS WITHHELD FOR A BETTER REASON THAN MINE. I had it on caution
about untested generalisation; the Decoder points out it is on title_jp and
MISSION section 7 scopes out "localisation beyond English", so it is not a
question this port has to answer and the parked Japanese capture does not need
reviving for it. authored/rendering.json now gives scope first and undecidability
second. Widening scope to close a residual would have been the wrong trade.

9f6959c7ca port: implement the decoded leaf composition -- and it does not close the 1.82%
The Decoder decoded the rule I refused to guess: draw the leaf on its own
timeline, do NOT multiply the parent's alpha in. Multiplying is refuted rather
than unsupported -- at the fitted time the parent has expired, so leaf x parent
predicts zero for both quads and the sweeps would be invisible. They are drawn.

Implemented: `_draw_leaf` runs the leaf unclamped, like the spinning ring and for
the same reason -- held at its own rest.t the leaf sits at x=1521, entirely off
the right edge, so `holding` would delete the sweeps rather than settle them.

AND IT CHANGES NOTHING MEASURABLE. The title is still 1.82% against the oracle:
1.82 at t=261, 1.81 at t=355, 1.79 at t=420. At t=355 my interpolation puts the
leaf's top-left at x ~ -324, off-screen left, where the Decoder's model puts the
quad's CENTRE at 981. Those cannot both be right, and it is not something to tune
away -- it is a disagreement about how the leaf's keyframes become a placed quad,
most likely in the pivot and the rotation about it. Handed back with both
numbers.

So: the exporter no longer drops the data, the composition rule is implemented as
decoded, and the port's largest oracle gap is exactly where it was. Fixing the
export was necessary and not sufficient.

TWO FLAGGED ELEMENTS DELIBERATELY NOT DRAWN, in authored/rendering.json with
reasons. title_jp/ptlogo_eff2 (parent 125%, leaf 100%) is the same shape and is
the element DECISIONS has recorded since P1 as the largest render disagreement --
but the Decoder said plainly "I have not tested it", and drawing it would extend
a decode past the case it was fitted on. pgloading_loop5's leaf is scale (0,0),
and scale-0 is one of the three historical failures this corpus names.

Neither can be adjudicated here: title_jp has no oracle capture, and
verify-screen compares against a renderer that draws no leaves at all, so ANY
leaf drawing increases that divergence whether right or wrong. Its max went
155 -> 232 when they were drawn, and that number is not evidence in either
direction.

ffb54429fb port: S00A is closed as not obtainable, and Q5's shape is tighter than "unstable"
Three things folded in from the Decoder, none of which change the export.

S00A IS NOT OBTAINABLE HERE and it is the game that stops it, not the drive. The
drive works end to end -- main menu +0.999, newgame-difficulty +0.999,
newgame-selectdata-crash +0.997, with the focus detector validated live against a
known transition rather than trusted -- and then the guest throws at
PC: 0x82307128 x349 with no S00A stream ever decoding. Recorded in BLOCKED as a
route finding, with the consequence for me stated: THE CENTRE-CHANNEL RESULT
RESTS ON ADV ALONE. S00A was wanted precisely because its second stream is
digital silence where ADV's is a 0.60x copy.

Q5 GAINED TWO POINTS and the shape is sharper than "it varies": TUTORIAL x3, NEW
GAME x3 over six boots, and no other item ever observed. That does not change the
port's authored initial focus -- NEW GAME is still one of exactly two observed
states and is the state of the committed capture -- but it changes what would
REFUTE it, so the authored `why` now says so: a boot opening on LOAD GAME,
OPTIONS or EXTRAS breaks the two-way shape, and a rule predicting the split
deletes the entry outright.

`which-focus` NEEDS GODOT AND THE EXPORT TREE, so it cannot run in the RE
container. Recorded in its own header rather than left for the next agent to
discover, along with the pointer to the capture-only alternative and that tool's
own caveat: its offline controls are its calibration inputs, which is
self-consistency and not validation.

3d3d620913 port: the capture has NEW GAME focused, and my harness had been rendering no focus
The Decoder attached an honest caveat to its reproduction of the tone-curve
refutation -- its bins included the focus-state mismatch, so it was "not a clean
second opinion". Removing that caveat found a defect of mine.

IDENTIFYING THE FOCUSED BUTTON, with a known-answer control. Walking focus
through all five buttons and comparing each against a capture:

                    vs -options-focused    vs live-main-menu
  ptbtn01 NEW GAME        6351                   531
  ptbtn02 LOAD GAME       7087                  7094
  ptbtn03 TUTORIAL        6230                  6237
  ptbtn04 OPTIONS         1292                  6364
  ptbtn05 EXTRAS          6073                  6080

The control picks OPTIONS by 4.7x -- the answer its own filename gives -- so the
test is trustworthy, and live-main-menu.png has NEW GAME focused by 11.5x. That
is what the port already focuses. Corroboration, NOT a decode: Q5's instability
stands (four boots gave TUTORIAL, TUTORIAL, NEW GAME, NEW GAME) and this
identifies one frame rather than a rule. Recorded in the authored entry.

THE DEFECT: `verify-capture` rendered menus with `--screen=`, which draws no
focus record, so it had been comparing main_menu to the oracle in a state the
oracle was never in.

  main_menu  0.25% differing, RMSE 14.79  ->  0.06%, RMSE 13.21
  extras     0.46%, RMSE 15.29            ->  0.20%, RMSE 13.38

A 4x improvement that was entirely my harness posing the port wrong rather than
the port drawing wrong. The first run of a new correctness harness reported a
discrepancy and three quarters of it was the harness.

AND THE DECODER'S CAVEAT RESOLVES TO NOTHING, measured rather than assumed:
re-deriving the transfer curve on the correctly-posed pair gives 1.20 / 1.26 /
1.18 / 1.10 / 1.03 / 0.94 at render 8..48, unchanged from the mismatched run. Its
reproduction stands as a second opinion after all.

7c918006e8 port: the PRESS (A) plate pulses -- authored per element, because 82 of 212 share its shape
The human listed pulsation as first-class and the port drew nothing: the plate's
focus record `ptbtn00f` was never reached, because press_start has no `buttons`
and nothing is focused. That it LOOPS is measured -- the corpus timed the period
four times (2.12 / 2.19 / 2.34 / 2.31 s) and you cannot measure a period unless
the thing repeats.

THE RULE I WAS GOING TO WRITE DIED IN THE CENSUS. The spinning ring is a rule in
the renderer because it has a disc-wide check: 16 of 212 elements match its shape
and all 16 are focus rings. The analogous shape for a pulse -- keyframes varying
only in alpha, first alpha equal to last -- matches 82 OF 212, including
ptcopyright, palogo_sqex, ptmsg and every _eff fade. A renderer rule on it would
make the copyright notice pulse. Narrowed to focus records it matches exactly one
distinct element, and a rule justified by n=1 is a special case wearing a rule's
clothes.

So it is a LOOKUP in authored/timing.json keyed <screen>/<element>, with the
census recorded beside it so nobody widens it later.

The period is 129 units -- the element's own group under the port's existing
model: last timed keyframe t=105 plus the authored exit_ramp_units of 24. No new
constant. 2.150 s at 60 units/s, 2.295 s at the ~28.1 fps the emulator presents,
against measurements of 2.12-2.34.

IT IS A CHOICE AND THE ALTERNATIVE IS STATED: restarting at the group's first
keyframe (t=6) instead of 0 gives 123 units = 2.050 / 2.189 s, also inside the
measured spread. Nothing separates them. t=0 is taken because it is where every
other group starts -- consistency, not evidence.

Verified the way the ring was, by bit-identity one period apart. 20 periods is
43.00 s = exactly 172 film frames: frames N and N+172 differ by 0-1/255, while
the control a quarter-second off (43.25 s) differs by 58.7/255. On the held boot
title the glow-box mean swings 26.0 <-> 37.7.

bb9626defe port: the game decodes all three voice streams at once, and two baseline rows were comparing blank frames
TWO FINDINGS, one mine and one handed to me, and the second retires a premise I
built on twice.

THE P1 BASELINE HAD ROWS THAT PROVED NOTHING. `build_12` and `build_15` render
pure black in BOTH renderers -- mean 0, max 0 -- so the difference is zero and
`verify-screen` scored them `max 0  over3 0  OK`, the strongest verdict it has.
Two of sixteen rows were comparing nothing against nothing. Worse than a missing
test, because a missing test is visible in the count.

Cause isolated by a control, not by reading: `build_00`/`build_01` are the same
loading screen minus three elements and render fine (mean 1.913, max 214.5). The
dressed variants add `pgloading_eff00`, a 1280x720 primitive resting OPAQUE BLACK
at t=38 inside its own opening black hold, with no layer key so paint order puts
it last.

The rule I was about to write -- "rest.t before the last timed keyframe is the
pathology" -- was killed by running the census first: 152 of 212 elements in this
export have rest.t earlier than their last timed keyframe. It is the norm. What
is actually unusual is the CONTENT, and its reach is one: `pgloading_eff00` is
the only element in the export whose resting pose is a fully opaque full-frame
quad. One instance is not a rule, so the renderer is unchanged and the HARNESS is
fixed: a blank pair now reports BLANK -- both renderers drew nothing; this row
proves nothing. `status` is untouched, so an unrelated DIFFERS still fails.

THE VOICE EXPORT IS KNOWN INCOMPLETE. The Decoder booted Canary with
--xma_param_probe and the game decodes ALL THREE streams CONCURRENTLY, in three
XMA contexts whose byte sizes match the disc payloads exactly. So "three
presentations of one take, pick one" is refuted by the running game and the
question I had been arguing -- WHICH presentation -- has no answer.

This one no census could have caught. Every measurement was right: the streams
are equal-duration, one is silence, one is 0.60x another with the residual 26.8
dB down. The frame around them was wrong, and the file says ChannelMask 0x0002 on
all three. It took the running game -- which is the mission's own sentence
arriving in practice.

BEHAVIOUR HELD DELIBERATELY. An equal-gain 1/n sum of channel pairs is not a
downmix either -- MISSION section 6 pins an explicit matrix for exactly that
reason -- and summing cost S00A 6.02 dB when one stream was silence. Swapping one
guess for another on a message is what produced this entry twice. What changed is
that the wrongness is now LOUD, because this failure sounds like success: one
stream is clean audible dialogue. A top-level manifest warning per movie, the
console line, and the authored entry all say `1 of 3 streams`.

"They are 5.1" is recorded as the Decoder's HYPOTHESIS with its own
counter-evidence attached, and nothing builds on it. What settles it is asked: a
recording of the game's own output over ADV through the null sink, which turns
channel roles into a fit against an oracle.

Refutation attempt, survived: the Decoder's loading-screen variant map. Entries
0/1 carry 7 elements and 12/15 carry those seven plus baseeff, eff00 and loop5 --
exact in count and identity, and it is what made build_00 a control.

92f1436836 port: withdraw the dual-mono generalisation -- the measurement stands, the rule does not
I argued `highest_rate` had no case because ADV's higher-rate presentation is
dual-mono while its louder one is mono-in-stereo, so the extra bytes buy a
duplicated channel rather than fidelity. The Decoder tested that disc-wide over
the 28 three-stream cues: the stream-3/stream-2 size ratio runs min 0.0778,
median 1.2565, max 2.9163, sd 0.5057, with only 12 of 28 within 15% of 1.0, and
declared rates scatter with them. A 37x spread is not a duplicated channel.

The CHANNEL MEASUREMENT STANDS -- ADV chunk 1 is mono-in-stereo and chunk 2 is
dual-mono at -8.318574, this port's own decode, which the Decoder could not
re-run and did not dispute. What fails is the step from one asset to the format.

NOTHING IN THE EXPORT CHANGES. `loudest` is a per-asset content rule -- it reads
the peak of the streams in front of it -- so a scattering structural ratio cannot
undermine it. What changes is the REASON, in four places: authored/audio.json's
presentation_why, the selector comment in audio.rs, BLOCKED.md's row, and
DECISIONS.md. The honest statement is narrower: `highest_rate` was never refuted,
it was never argued for, and neither is `loudest`. That is why the entry is
marked CHOSEN rather than measured, and why one capture deletes it.

Recorded on the pattern rather than just the instance: this is the third claim of
mine in two iterations that generalised a single-asset observation, after "the
chunks are two stems" and "everything the sequencer paces off rest.t is late".
All three were true of the thing I looked at. The failure is reaching for the
rule a measurement would imply if it held everywhere and writing that down in the
same breath as the measurement.

Also noted, not mine and not affecting export_voice: S12B's three streams are
byte-size identical, and BIRD_224 is three-stream while not being a movie cue.

81ea5cb324 port: settle times measured -- the pacing was already right, and my own red flag was half wrong
THE TRANSCODE CACHE HAD NEVER HIT. `video::transcode` has carried one since P4 --
a `.cmd` sidecar with the command, the source size and the channel count -- and
`main.rs` clears the output tree wholesale immediately before the check, deleting
the sidecar and the file it stamps. Six exports in this session paid the full
Theora encode and produced five byte-identical files, roughly 48 minutes. Nothing
reported it, and nothing could: a cache is silent either way and the only symptom
is a wall clock that looks like the job being slow. The wipe now spares `video/`
and `prune_videos` deletes anything in it this run did not claim, so the
wholesale guarantee is kept rather than traded. A re-export is 20 s.

SETTLE TIMES, MEASURED, and they refute more of my row than they confirm. The
principle holds -- the title's rest.t is 251 units = 4.183 s where its art
finishes at ~2 s -- but "everything the sequencer paces off that landmark is
therefore late" does not. Measured the port the way the game was measured, by
VISIBLE SPAN rather than arrival-to-arrival:

  publisher wordmark  port 4.25 s   game 4.297 / 4.604 / 4.370
  developer logos     port 3.50 s   game 3.508 / 3.503 / 3.366
  black hold          port ~0.25 s  game 0.2 - 0.3
  title -> plate      port 2.000 s (declared 120 units)   game 2.247 s

Dead on. My earlier reading compared the port's transition timestamps against the
game's visible spans, which differ by the exit ramp plus the black hold -- the
whole of the discrepancy I was about to chase, and the same definitional trap
that cost this corpus 0.48 s on the plate delay. Nothing in the sequencer is
changed. `dwell_seconds` stays null, now for a measured reason rather than an
absent one: `timing.json` said "if a capture ever times the real boot, this is
where that number goes", and the answer is that nothing goes there.

Not authored, deliberately: an (A)->menu dwell, which measures 3.763 s and
contains a 1.53 s guest load stall on a cold cache; and the menu build-in and
(B)->title, which rest on one run where the port is already within ~0.1 s.

THE VOICE PRESENTATION MOVED TO authored/, because the recommendation behind it
was withdrawn as self-contradictory and the choice is now unambiguously mine.
`voice.presentation` = `loudest`, and the reason to switch is a measurement, not
a preference: ADV chunk 1 is MONO-IN-STEREO and chunk 2 is DUAL-MONO, so chunk
2's extra bytes encode a duplicate channel rather than fidelity. That explains
the byte-rate difference and removes the only argument for `highest_rate`. ADV's
dialogue now exports at +0.3 dBFS instead of -8.7, which is the SE bound's
documented decode overshoot on a wave mastered at full scale.

d45da73bba port: P7 -- the new-game intro plays, and the two screens it skips are named out loud
S00A has been exported since P4; what P7 needed was something to play it and a
defined place to land. Both are here, and the interesting part is the gap.

The real chain is NEW GAME -> DIFFICULTY -> SELECT DATA -> (A) on a save slot ->
~4.5 s -> S00A. DIFFICULTY and SELECT DATA are MEASURED destinations that are not
GP_TITLE builds, so no screen file exists to go to. The port jumps from NEW GAME
to the one thing in that chain it has -- and the whole design is about not
letting that read as a sequence:

  * MenuFlow.accept returns a new kind, `video`, rather than folding this into
    `blocked`, because the caller has to announce the skip and a distinct kind is
    what forces it to;
  * the runtime prints the skipped screens by name on every run;
  * flow.json carries `skipped_chain` as DATA, so what is missing lives beside
    the decision instead of inside a GDScript string.

After the movie the port returns to the title. Authored, and it has to be: the
game goes into mission 1 and gameplay is out of scope. The ~4.5 s before the
movie is left EMPTY on purpose -- GP_TITLE does carry a loading screen and 4.5 s
is about the right shape for one, which is exactly why that belongs in BLOCKED.md
and not in flow.json.

`--script`'s 20 s per-step timeout would have killed every movie run at step 1.
Raising the constant would have been wrong the other way: a movie stuck at frame
0 would then hang the job, and a job that waits is worse than one that fails. The
test is now LIVENESS -- while get_stream_position() advances the deadline moves
with it, and a stalled movie still trips the same 20 s.

Found while looking: GP_TITLE's four unnamed builds (entries 0, 1, 12, 15) are
LOADING screens -- every element in all four is pgloading_*, and LOADING is one of
the three names the decoder read out of the title part's state function. NOT
renamed here: which member of each pair is which locale is an inference, and a
name stops being questioned once written. Handed over.

One of them is a second casualty of the rest.t problem, and a worse one:
pgloading_eff00.prm rests OPAQUE BLACK at t=38, so anything drawing that screen
at its declared rest paints a black rectangle over all of it. The title's case
only dimmed a frame.

REFUTATION, attempted and SURVIVED: HANDOFF says "exactly the six screen builds
carry the black .prm quad while the six overlays do not". Counting bundles with a
full-screen black primitive gives 8 and 4 -- build_12/15 carry one too. But
theirs runs black -> held -> clear where the transition quad runs black -> clear
-> black, so read strictly as "the quad whose group is the transition" the claim
holds. Recorded anyway: there are two kinds, and the naive census over-counts.

Gate: NEW GAME -> S00A plays 93.75 s against a declared 93.9 -> title, with
98.453 s recorded off the Master bus. What that does NOT show is that S00A's own
audio is in the mix -- bed and movie were not separated in this run, and the
write-up says so.

measurement adds is only that the turn repeats rather than stopping -- which
"groups hold" could not decide, because 0 and 360 are the same pose.

`spin_period_units` is structural and narrow on purpose: two keyframes,
differing in nothing but rotation_deg, by a full 360, first timed and second
untimed. 16 of 212 elements in this export match and all 16 are focus rings,
zero false positives. That check is the point -- the measurement was taken on
ONE button of ONE screen, and a rule that caught anything else would be
extrapolating it to elements nobody watched.

Verified on the port's own render with the RE agent's own control: bit-identical
one period apart across the whole frame, 3.6/255 inside the ring's box at
quarter-period steps, and box luminance conserved to 0.027 % over eight phases
-- which is the observable they used to separate rotation from a pulse. Not
claimed: direction (no signed angle was ever measured) and phase across a focus
change (their run held focus throughout).

P3 -- the plate. Last iteration I refuted their authoring instruction and
shipped it anyway rather than pick between two of their numbers. The refutation
held and the answer came back better than either option I offered: AUTHOR
NOTHING. Both builds run on one clock started together and the plate arrives at
its own declared t=238. The 2.13 s constant is deleted.

The premise that failed was mine: rest.t IS NOT WHEN A SCREEN SETTLES. It is the
last hold keyframe before the exit. ptlogo1 stops MOVING at t=42 and then creeps
5 px and 31 alpha steps to t=251. Reading rest.t put build 4's arrival at 4.350 s
instead of 1.967 s, and the "2.51 s, which is not a landmark of anything" I sent
them is that error wearing a decimal point. 238 - 118 = 120 units = 2.000 s
against a measured 2.135 s at 28.1 fps presentation. Checked against my own
export before touching anything.

`ScreenView.settle_time()` still uses rest.t, and so the boot sequencer paces
every screen off the wrong landmark. NOT changed here: "visible arrival" is a
heuristic and getting it wrong re-paces everything. Filed, and asked for a timed
boot instead now that their oracle is live.

REFUTATION: two of their pages measure the same declared 120 units of wall clock
during a static hold and disagree by 2 % -- plate 2.135 s (28.10 fps implied),
ring 2.177 s (27.56 fps). That is seven times the plate page's own 6 ms
run-to-run agreement, and it lands on the argument that page uses to justify
itself: "the build-in is where frames are dropped; the static hold is not". Also
the ring page's band, 27.6-28.8 fps, does not contain its own measurement -- the
mean needs 27.56 and four of seven spacings are outside. Filed, not worked
around: my port uses the declared 120 units either way.

Sylpheed port agent
4f767e72f6 port: P3 -- the boot title gets its PRESS (A) plate, and two of the RE agent's numbers do not agree
ScreenView now draws two builds at once, which it never had to before. It is a
second ScreenView in the same SubViewport rather than a subordinate screen
inside one: each build has its own timeline, its own textures and its own hold,
which is the entire content of the finding, and Node2D siblings already paint in
tree order. `paint_order` still means what it meant -- an ordering WITHIN a
build.

The delay is authored in flow.json on the BOOT STEP, not on the `title` screen.
What was measured is the boot title; whether the plate is there when the title
is reached again -- (B) from the menu, or after the attract movie -- is not, and
hanging it on the screen would quietly claim that it is.

REFUTATION, and it is the substance of this commit: the RE agent's authoring
instruction does not reproduce the RE agent's own measurement, and the gap is
3.97 s. The instruction is "when build 4 has settled, wait 2.13 s, composite
build 2". But build 2 has a group and this port plays groups -- ptbtn00 is alpha
0x00 at t=214, still 0x00 at t=236 while it slides 10 px up, and 0xff only at
t=238, which is 3.967 s at 60 units/s. So the plate is first VISIBLE at
settle+6.10 s, while what was measured -- the glyph counter leaving 154 -- is
visibility at settle+2.13 s. Both groups starting together puts it 0.38 s BEFORE
settle; build 2 starting at settle puts it at settle+3.97 s; landing on the
measurement needs build 2's group to start 2.51 s after build 4's, which is not
a landmark of anything.

The measurement is untouched -- it is an observation of the running game and I
have no standing to doubt it. What is refuted is the step that turns it into an
authoring rule. So the port ships the instruction, prints the discrepancy on
every boot, and files the row. Same call as the BGM sub-waves: a port that
quietly picks the number that looks right destroys the evidence, because a
corrected boot looks exactly like a correct one.

Also refuted, and it was mine: BLOCKED.md has said since P2 that "no element's
alpha reverses direction anywhere in this export, so nothing pulses". ptbtn00
reverses -- 0x00 -> 0xff -> 0x00 -- and it was in the export the whole time. The
claim had been checked against the screens P2 happened to be animating. The port
still draws no pulse, because no reading of this group yields the measured
2.24 s: the whole group is 4.47 s and from its first keyframe 0.90 s.

Gate: `--boot --capture=` writes one frame of the composited end state, instead
of the 600-PNG filmstrip that was previously the only boot artifact.
`--screen=title --overlay=press_start` raises the same composite in two seconds
for anyone who does not want to sit through 137 s of Theora.

2ad839460c port: P6 -- the menu has sound, and the BGM I "chose" was decoded all along
The three Static.slb cues and the menu bed now export to Ogg Vorbis and play.
`sylpheed_formats::media` does the assembly; nothing in port/ has heard of XMA.

Three things this milestone got wrong before it got right, all recorded in
docs/port/DECISIONS.md because the corrections are the useful part:

1. The cue offsets were a Rust `const` in the exporter. They are MEASURED, not
   decoded -- a measured value compiled into the exporter is a measurement
   wearing the costume of a decoded field, and nobody deletes it because nobody
   can see it. They are authored/audio.json now.

2. I picked BGM_001 and wrote a careful `why` calling the choice arbitrary. The
   menu's music is BGM_103, and it is in HANDOFF at 9ca1eb5 -- the exact commit
   BLOCKED.md says that row was reconciled against. Not stale: wrong when
   written. I had summarised a negative without its reach, so "the TABLES cannot
   say which BGM a screen plays" became "it is not on the disc". One word of
   scope was the whole answer, and the export failed only because BGM_001
   without its .slb extension hashes to nothing. That is luck, not design.

3. The comment above the BGM sum argued for unity gain "because halving is a mix
   decision nobody made". It clipped at +1.8 dBFS. 1/n is the smallest constant
   that provably cannot clip -- the same reasoning video.rs already carried for
   its 5.1 downmix, in this repository, unread.

Unsettled and shipped as such: media::sound_bank_riffs returns THREE sub-waves
for BGM_103.slb where HANDOFF Q10's census says exactly two (the third is the
leading headerless region slb.rs emits for the voice path). The exporter sums all
three and writes a manifest warning, because which bytes belong together is the
decoders' question, not this exporter's -- and dropping one would destroy the
evidence, since a corrected export looks exactly like a correct one. Raised with
the Decoder; row in BLOCKED.md.

The gate is a null control, not a peak reading. A master-bus WAV that is
non-silent proves nothing -- the bed alone would look identical. So the same
scripted walk was run with <- in place of <v>, which fires no cue (Q5, measured),
and the difference is one 0.55 s burst at t=1.10 s and silence everywhere else.
The first attempt at that control returned bit-identical zero and I nearly filed
it as "cues never reach the bus": both runs ended at 1.115 s and the first press
lands at 1.17 s. A null result from an instrument that was not running is not a
null result.

Refutation attempt: HANDOFF Q8's three cue durations. They looked attackable --
0.133/0.172/0.169 s per packet, no shared rate -- but an XMA1 packet carries a
variable number of 512-sample frames, and the three come to 50.0/32.3/95.3
frames. Measured off the decoded Ogg: 0.533, 0.344, 1.016 s, every published
digit. SURVIVES, with its reach stated -- it confirms the assembly path and my
transcription, not the event bindings, which only an oracle can retake.

9256722a11 port: P5 end to end -- and the port's title never says PRESS (A)
The P5 gate walk starts on a screen. This runs the whole objective instead, and
it is the only thing that would have found what it found:

  xvfb-run -a godot --path port -- --boot --play \
    --script=accept,down,down,down,down,accept,cancel,cancel --shots=/tmp/e2e

publisher wordmark -> developer logos -> ADV (151.9 s) -> title -> (A) -> main
menu -> navigate -> (A) -> EXTRAS -> (B) with focus restored to ptbtn05 -> (B)
-> title. 166.76 s, exit 0, nine frames. Shared as 1788003274-e68367e787d5.

THE PORT'S TITLE DOES NOT TELL THE PLAYER TO PRESS (A). The boot's last step is
`title` = GP_TITLE build 4, and build 4 has NO `PRESS (A) BUTTON` plate. P5 has
just made (A) the only way off that screen.

Not a guess about the art -- both states are captured off the running game and
differ by exactly that plate (live-title-build4-no-plate.png vs
live-title-press-a.png), and the plate is ALREADY EXPORTED as `press_start`,
build 2, sitting in export/screens/title/ unused by anything.

RECORDED, NOT FIXED, and the distinction is the point. This is P3's gate that
P5 exposed, and fixing it needs two things the port does not have:

  * WHICH state an idle post-boot title shows -- build 4 alone, build 4 with the
    plate over it, or build 4 THEN the plate after a delay -- is BEHAVIOURAL.
    The game demonstrably has both states and nothing says which follows the
    intro. The port has no oracle for a sequence; that is the Decoder's.
  * showing it means DRAWING TWO BUILDS AT ONCE, which this port has never done
    -- every mode loads exactly one screen. That is a change to ScreenView, not
    a line in flow.json, and it is not being smuggled in under a navigation
    milestone on the strength of "it looks more right".

Filed in BLOCKED.md. P5's gate is (A) into a submenu and (B) back; both work.

Two smaller things the same run found, both fixed:

  * the boot step's `why` still said "nothing takes the title's place until P5
    gives it somewhere to go". P5 has. Now says what is true: `--boot` STOPS on
    the title (a boot that ends by fading to black looks like a crash) and
    `--play` HANDS THE HELD TITLE OVER -- the stop is not a bug and the handover
    is not another boot step.
  * an empty focus printed as a line that trailed off, reading like a value had
    gone missing rather than like there is none. The title is a screen with no
    `buttons` that still takes (A), so it now prints
    "(none -- this screen has no focusable item)".

Also confirmed: entering a submenu directly (`--menu=extras`) and pressing (B)
enters the parent at its AUTHORED initial focus, not a restored one. There is no
history to restore and MenuFlow.cancel only claims a restored focus when the
stack agrees about where it is going.

eef45ecfd6 port: P5 -- the menus navigate, and the focus ring is drawn wrong on purpose
P5's gate is "a human clicks through it". The artifact is a scripted walk that
proves the wiring rather than the intent -- up (wraps 01->05), five down, (A)
into EXTRAS, down, (B) back, landing on the main menu with focus RESTORED to
EXTRAS, ten PNGs one per settled step:

  xvfb-run -a godot --path port -- --menu \
    --script=up,down,down,down,down,down,accept,down,cancel --shots=/tmp/p5

--script posts InputEventAction through Input.parse_input_event so the presses
arrive at _unhandled_input exactly as a d-pad's would. Calling MenuFlow directly
would have been shorter and would have proved nothing: the wiring between a
press and the cursor is the part most likely to be broken, and a direct call is
exactly the part that skips it.

Derived vs authored, which P5 is the easiest place to blur:

  * DERIVED -- the ORDER of the items, from each screen file's `buttons`, which
    the exporter already fills from button-role elements sorted by resting Y.
  * AUTHORED -- destinations, initial focus, what (B) does, and left/right being
    a no-op. All measured off the running game (HANDOFF Q4/Q5) or chosen, none
    on the disc, all in authored/flow.json with a why.

Four of five main-menu destinations are `goto: null` with a `blocked` note. That
is a MILESTONE BOUNDARY, not an unknown -- DIFFICULTY, the save list, the lesson
list and OPTIONS were all measured and live in archives this export does not
carry. `blocked` and `none` are kept apart so nobody later "discovers" the gap.

--headless CANNOT DRAW, and the port hung instead of saying so.

Measured, not assumed: under --headless Godot's dummy renderer never emits
RenderingServer.frame_post_draw, so every capture path awaited it forever --
--capture since P1, --film since P3, --shots as of now. With stdout block-
buffered the observable behaviour was SILENCE, FOREVER, which in a loop reads as
a job still working. Isolated by `--quit` (prints, exits 0) vs `--capture` (zero
bytes, killed at 40 s). Now those three flags refuse at STARTUP naming the
xvfb-run line that works, and --script no longer waits for a frame it is not
going to photograph -- so headless walks the menus in 4.5 s as a cheap
regression check needing no X server.

REFUTATION ATTEMPT, against the Decoder's 7eeae30 point 2 ("the oracle confirms
the game renders the ring's rotation"). Aimed there because PROTOCOL says to aim
at a claim the port is about to build on that rests on an estimator whose own
control the Decoder reported as +/-19.8 deg. IT SURVIVES, more strongly than
claimed.

Both captures draw the SAME sprite (ptbtneff01) 240 px apart, so "is it drawn
rotated" becomes "are these two crops one image at a different angle" -- no crop
offset needed and no reference to our own renderer. 360-bin angular luminance
profile over the annulus, circularly cross-correlated. Two controls first: known
rotations 0/30/90/150/210/270/330 recovered with 0 deg error, and a ring-free
patch of the same capture peaks at 0.369, so the estimator does not manufacture
matches. Then: A vs B 134 deg (corr 0.968), sprite vs A 76 deg, sprite vs B
210 deg -- and 210-76 = 134, which nothing in the method forced.

So 0 deg is NOT A POSE THE GAME SHOWS, and screen_view.gd draws the ring at
0 deg. That is now stated in the code as known-wrong rather than suspected. The
port did NOT start spinning it: the period has two unknowns and both are the
Decoder's -- the second keyframe is untimed, and "groups hold" predicts a stop
at 360 = 0 which contradicts both captures. Two frames of one focused button a
known time apart settle it. Filed in BLOCKED.md and asked over the channel.

BLOCKED.md's staleness check was half a check. It tested whether that page is
stale relative to HANDOFF; it cannot see the other direction, and the other
direction is what happened -- 7eeae30 lands 27 minutes AFTER HANDOFF was last
written and answers a question HANDOFF still lists as open. Added the missing
half: `git log --oneline 9ca1eb5..HEAD -- docs/re/`.

Also recorded, since the two were nearly confused: the ring's annulus centroid
lands within ~0.4 px of its design position under a ZERO crop offset, which
corroborates ORACLE-CAPTURES' "1279x675, top-left aligned" on a feature nobody
chose for the purpose. The earlier "text bands at design y + 23" is an offset
WITHIN the button sprite, not a crop offset.

Merges the Godot port into the reverse-engineering repository, preserving both
histories -- 1019 commits of corpus plus the port's 31, brought in by subtree
merge and then moved into place so git can follow each file across the rename.

The reason is not tidiness. The two-repo split forced the exporter to depend on
the decoders by pinned revision, and that created a whole class of failure that
now disappears: a sha reachable only from a topic branch, orphaned by a
squash-merge, breaking a fresh checkout silently at build time. It also forced a
live read-only mount of one agent's working tree into another's container, which
is why a contract file could move mid-iteration. With a path dependency, a
decoder change and the exporter change it requires land in the same commit or
not at all.

Canary stays separate: it is a fork tracking upstream.

New structure for the long term:

  docs/game/     how the game is NAVIGATED -- menus, modals, prompts, alerts,
                 and in-game flight. Written so nobody rediscovers it. Mostly
                 open questions on purpose; the in-game tutorials are the
                 resource for the flight half.
  docs/port/MODDING.md
                 modding as a constraint on the exporter TODAY, not a later
                 feature: one logical asset in one file (the disc splits nearly
                 everything, and resolving that is the exporter's job), names a
                 person recognises, PNG/OGG/OGV/JSON only, base-and-overrides so
                 re-exporting is always safe, provenance in every file.
  data/base + data/mods
                 generated tree and drop-in overrides, both gitignored
  exchange/      transient inter-agent files, deliberately outside history
  docs/agents/   the team protocol

Both the README and the navigation doc lead with the correction that cost the
most: the oracle is the real game under Xenia Canary. Reborn's renderer is a
hypothesis under test, it has been wrong, and treating it as ground truth
propagated into three documents and both agents before a human caught it.

Scripted modding stays possible without being built: no screen name is hardcoded
in GDScript and there is no native code in port/, which is what Godot Mod Loader
needs to be able to substitute behaviour later.
