Their withdrawal gave coordinates to check my renderer against, and my first
measurements looked like a contradiction: phase-to-phase differences span the
whole frame against their 400 px quad tracking x 921->1041. Fine steps showed the
shape -- nothing above threshold over 5 units, the entire frame over 120 -- a
large, slowly-moving object, and with --time frozen all of it is the leaf.
Reading the leaf record from my own export resolves it. ptloop01: leaf pteff03,
span 600, x track -639..1521, scale (100,600). ptloop02: span 720, scale (100,800).
Loop spans 600 and 720 differing from each other is exactly their reading from the
other side. Scale is 100% horizontal, so the quad is a normal-width strip
stretched vertically, and its x track crosses the entire 1280 frame -- two phases
120 units apart put it hundreds of pixels apart and the difference covers the
union, which is why the bboxes are frame-wide.
Their 921->1041 is a segment of that track, not its extent. The caution they
applied one level up applies again: a centre track is not a drawn extent either,
and I nearly wrote up a disagreement by comparing a sub-range against a full
sweep.
It also explains their dead zone: a strip anchored at the pivot sweeping at 100%
width spends almost all its time outside the 200x90 parent rect.

Last iteration I pinned the leaf at phase 0 for reproducibility and said which
pose the game shows was not settled by it. Asked the capture, with the decision
rule stated first: the spread must beat the noise floor decisively or 0 stays an
admitted arbitrary choice.
Phase 0 is the global minimum at 13.2059, rising to 14.08 mid-cycle and returning
to 13.2065 at 600 units -- margin 0.44-0.88 against a run-to-run floor of 0.0565,
8-15x, which meets the rule. 0 and 600 agreeing confirms the cycle closes,
independently supporting the leaf's declared span.
The Decoder's point is what makes it readable: the gamma offset moves every
candidate together and nearly cancels in the ranking, so nine renders differing
only in leaf phase compare cleanly on a ~13.2 floor nobody can remove.
Broad minimum -- 0 and 15 units identical to four decimals -- so this constrains
the phase to the first 15 units of a 600-unit cycle, not to a point, from one
capture of one screen.
And the sweep that nearly said the opposite: --leaf-time takes SECONDS, so my
first sweep of 0..500 was 0 to 30000 units, every value past the group end,
returning 13.2059 six times. Third instance of the seconds-versus-units confusion,
after --time=50 and after I wrote the identical-output tell into METHOD. Made
worse because 0 and 30000 genuinely coincide, so the flat reading was partly real.

Last iteration I enumerated three free-running clocks, wrote that the leaf is
pinned only by --leaf-time, then tested reproducibility without passing
--leaf-time and concluded nothing free-runs on the menu path. The answer was one
paragraph above the experiment that contradicted it.
My own flagged weakness found it: deliberate wall-clock variation via
--script=wait:N, putting the capture at t=96 units against t=369. Spin pinned
only, wait 0.5 vs 5.0 differs by max 91.19 per channel; with --leaf-time=0 added
it is byte-identical. draw_leaf_for is ptloop01/ptloop02, present on main_menu and
not just the title, which is why that row drifted.
verify-capture passed --loop-phase=0 and not --leaf-time=0 -- I fixed the clock I
had been bitten by and left the one I had merely listed. Enumeration without
follow-through fails exactly like no enumeration.
Both are now pinned at all six render sites. main_menu returns 13.21 across three
runs and two renders after different waits are byte-identical.
The number moved 13.26 -> 13.21 and that is NOT an accuracy improvement: pinning
the leaf at phase 0 puts ptloop01/02 at one specific pose rather than wherever the
wall clock left them. A different configuration, now reproducible. Which pose the
game shows at rest is not settled by this.

The Decoder's point was that this is an unenumerated set, not a missing guard. The
enumeration is possible on my side and found a THIRD clock: the leaf sets
holding = false explicitly and reads time_units, pinned only by --leaf-time or
--time, biting on loop_leaf_on_screens = [title]. I would not have found it by
waiting for a row to drift.
But the general answer is a test that fails when the set is non-empty. Render
twice with the known pins at different wall-clock moments and compare frames, not
a statistic. --screen + --time + --loop-phase: all 16 byte-identical, though
--time freezes time_units itself so that pins every derived clock. --menu
--script=wait + --loop-phase, where the drift lived: frames differ by 4378 px --
but max per-channel 2.86 against 158.4 for a genuinely moving element, 55x apart.
Nothing moves; the residual is rasterisation noise. The discriminating scale is
what makes the test an answer.
And the reason I nearly missed it: last iteration I reported three pinned runs
returning 13.26 and called the harness reproducible. verify-capture prints RMSE to
two decimals and the residual is 0.0565 -- below its own resolution. The frames
were never identical; the statistic could not tell. I verified reproducibility
with an instrument that rounds away the thing being verified.
Conclusion unchanged: 2.86/255 changes no result.

verify-capture's main_menu row reads 13.30 / 13.27 / 13.25 / 13.26 across runs
this session while every other row is identical to the digit. I cited those
numbers repeatedly, including in the rest() adjudication.
Cause: the focus ring spins on time_units raw rather than the pose clamped by
holding -- deliberate and correct, since the ring is the one thing on a settled
screen that keeps moving -- so its angle at capture is set by the wall clock.
extras is stable because nothing there spins.
--loop-phase already existed and did not cover it: it pins the looping focus
record phase, while the spin is a second free-running clock I guarded once and
never connected. Extended loop_phase_units to pin the spin too, and verify-capture
now passes --loop-phase=0 at all four render sites.
The control matters because the drift was intermittent -- three unpinned runs gave
13.25, 13.26, 13.26, so three pinned runs agreeing would prove nothing. Phases
0/30/60/90 give 13.2583 / 13.1991 / 13.2637 / 13.2588: the pin is live and the
0.065 spread is the whole of the observed drift.
Non-finding recorded so nobody mines it: phase 30 scoring lowest is not evidence
about the ring's real phase -- 0.065 against a ~13.2 gamma floor is 200x too
small. A margin only means something against the noise it sits on.
No conclusion changes: the smallest margin any of them turned on was 0.14%
differing area.

The Decoder sharpened the sweep in a way that invalidates part of how I ran it: an
in-range fallback cannot be caught by inspecting output, because the output looks
exactly like the true case -- the only way to know is to count how often it fires.
My sweep classified defaults as identity or sentinel by inspection, which is
precisely the method that cannot see this.
Counted: rotation_deg -> 0 fires 0 times in 866 keyframes and 178 rest poses, and
ramp is present in authored/. So rotation is read, not invented -- the same
conclusion they reached for design size, reachable only by counting.
The count exposed one I had waved through twice: black_hold_units defaults to 0.0
and its authored value IS 0, so deleting the entry would be invisible -- same
behaviour, no error, and the reasoning in black_hold_why (four measured gaps, why
0 over the better-fitting 4 or 6, the tripwire) silently stops applying. Fixed the
same way as exit_ramp_units: fallback is -1.0 and an absent key raises an error
naming what was lost.
The control is the demonstration: key present 0 errors, key deleted 1 error, and
the render byte-identical either way. No output inspection could have detected the
deletion.
Does not change the value: still 0, still wrong by 4-6 units on three of four
measured transitions, still no rule. Only its absence is now audible.

The exit_ramp_units catch generalises: deleting an authored value does not remove
it if something supplies it silently, and authored/ is where a reader looks and
does not find it. Swept both halves of what I own.
GDScript: every keyed lookup with a fallback, cross-checked against the 121 keys
present in authored/. One hit -- exit_ramp_units, the case already fixed -- which
makes it the sweep's own positive control: the detector found the known instance
and nothing else. The other numeric fallbacks are identity or sentinel and invent
no quantity.
Exporter: 14 serde(default) sites, all attaching to Option, Vec or map types,
where an absent key becomes None or empty and asserts nothing.
My classifier produced a false positive I nearly wrote up: it flagged
also_export: AlsoExport as a semantic default because the type name lacks a
container prefix. AlsoExport is a type alias for a BTreeMap. Classifying a type by
the spelling of its name is the same proxy reasoning as inferring an era from a
line count.
Negative result, but from a check that demonstrably finds the known case.

ScreenView.exit_ramp_units defaulted to 24.0 -- the constant HANDOFF ask 2 told
this port to author and that it refused, since the file's own ramp is 10 units.
The authored entry was deleted as progress when the corrected record layout
removed the unknown, and the default plus boot.gd's timing.get(..., 24.0) made
that deletion a no-op.
Both use sites are unreachable on today's export (866 keyframes, 0 untimed), so
the branch is kept for an older export but no longer invents: the default is -1.0
meaning not supplied, and an untimed group now raises an error naming the screen
rather than fabricating a duration.
My first verification accused the change: main_menu 641941 px and extras 226009 px
changed, on a branch that cannot execute and with no error raised. The cause was
--screen=X --capture= firing at an uncontrolled instant -- t=9.00 in the earlier
run against t=8.00 in the later one, one unit apart mid-build-in. Three runs now
are byte-identical, so it is not noise; the instant is stable within a session and
moves between them. Re-run with --time=1.0 pinned, old against new is
byte-identical on all four screens.
Records the harness limitation: --screen=X --capture= cannot be used for
before/after comparison on an unsettled screen, which also explains the earlier
settle-vs-rest confound.
Also corrects my overstatement that other tools call the CLI -- verify-screen is
the only one, checked.

Told the Decoder their diagnosis was wrong. They were right. ui_layout.rs is md5
b6c19d08 in my working tree, at HEAD, on my pushed branch and on origin/main --
one file, stale marker present, tree clean.
What misled me is the same trap a third time: CARGO_TARGET_DIR is a shared
/sylph-home/port/target-container, so two source trees write one binary and cargo
fingerprints per source path -- each build reports Finished while the binary on
disk belongs to whichever tree wrote last. A CLI built from my workspace is
3a39fce (stale, rest t=70), identical to one built from origin/main; the binary
verify-screen actually used was 8e0aa76 (fixed, rest t=12), from a tree nobody had
named. It happened to be the right era, which is worse than wrong -- it agreed
with the pin by luck and one rebuild would have flipped it silently, and title_jp
differs by 74507 px between eras.
verify-screen now reads the reference CLI's pteff00 rest instant and compares it
against the export the port reads, refusing to score if they disagree. Controlled
both ways: passes with the matching binary, refuses the stale one built from my
own workspace.
And the pin is load-bearing, not an annoyance to revert: the workspace crate is
stale, so the pin is the only reason the export is correct. Consequence worth
stating -- my published branch carries the stale crate, so anyone building
sylpheed-cli from it gets the stale decoder.

Last iteration I overturned check-all's allowance on a measurement of 0 pixels
between the two decoder eras, and rewrote the tool's reason around it. The two
binaries had the same md5: one built in a worktree at formats-pin-2026-08-30 and
one from the workspace, and both commits carry the record-layout fix. I compared a
binary with itself and reported the zero as evidence. The 508-line diff I cited
was real and irrelevant -- it does not straddle the fix.
Done properly against origin/main, verified stale by the Decoder's own control
(rest t=70 vs rest t=12) and by differing md5s: title 0 px, main_menu 0 px,
title_jp 74507 px -- reproducing their figure exactly, under their flags and mine.
My second hypothesis, that --animated masked it, was also wrong.
What survives: the era still cannot explain this script's rows, for a fact I had
not established -- both sides of the comparison are the FIXED era, since a binary
built from the pin and one from the workspace have the same md5. Right answer,
wrong evidence. The note now carries its condition: title_jp is era-sensitive, so
if the reference is ever built from a different era than the pin, that row's cause
changes.
Twice now a correct conclusion has come through a broken experiment, and both
times the tell was two things that should differ producing identical output.

They answered ask #2 -- the gap is deterministic, not a load -- and held me to
re-stating the choice against four measurements (0, 6, 4, 6) rather than the three
it was made on. That is my own standard for check-all's stale allowance turned
around.
The arithmetic moved against 0: it costs 2.0x the best fit on four measurements
against 1.7x on three, and is now the minority outcome, wrong on 3 of 4 where a
uniform 6 is wrong on 2 of 4.
Still 0, because the reason was never the fit -- it adds no black the game does
not have, and is measured-correct for a real transition rather than for an average
of them. Picking 6 because it appears twice is choosing a mode from four samples
when their finding is that a rule exists and nobody has found it.
But one leg is gone and is not being kept quietly: part of the case for 0 was that
the quantity might be machine-dependent and unauthorable. It is not. That removes
an excuse without supplying a value.
Added a tripwire: if the gap is non-zero in most transitions and no rule emerges,
omitting a real quantity stops being caution and becomes a different invention.
The port is wrong by 4-6 units on three of four known transitions and the why now
says so.
Also records as settled: the outgoing ramp is the declared final ramp, my {8,10,10}
against their measured multiset, two independent routes.

The Decoder measured the black gap on three transitions: menu->title 0 units,
title->menu 4, EXTRAS->menu 6. Not a constant, and 9 was outside the range
entirely -- wrong for all three by up to a sixth of a second of black the game
does not show.
Did not take the best-fitting value. A uniform 4 minimises total error (6 against
0's 10); that is fitting three samples. 0 has a reason that is not a fit -- it
adds no black the game does not have, the tie-breaker input_during_transition
already uses, and it is measured-correct for one real transition. The error is now
a missing gap of at most 6 units on two transitions rather than an invented one of
up to 9 on all three. Boot artifact unchanged at 0.0009% differing.
Their EXTRAS run vindicates the earlier refusal: B from EXTRAS goes black for two
completely empty frames, so the two-line change I declined would have been wrong
for two of three transitions.
Also: the declared final ramp is confirmed from my side (title 8, main_menu 10,
extras 10 -- their exact multiset), needing no constant. And exit_ramp_units
defaults to 24.0, the number HANDOFF told me to author and I refused, on a branch
that cannot execute: 866 keyframes across 16 screens, 0 untimed.
And origin/main is the stale era -- verified 0 145 left-right, tip 2026-08-29,
still carrying the pre-fix association. The per-iteration merge has been a no-op
for days, its 'Already up to date' reading as 'I am current' while meaning 'main
has nothing'.

The suite reported '2 DIFFERS, allowed: the pin is not on main, so this compares
two decoder eras', and I had quoted that for several iterations without testing
it. Built sylpheed-cli at formats-pin-2026-08-30 and at workspace HEAD and
rendered through both: title, title_jp and main_menu come out 0 pixels different,
despite 508 lines of difference in ui_layout.rs. The eras are not the cause, and
the allowance was excusing a real signal with a wrong explanation.
A second defect in the same eight lines: the expiry tested formats-pin-2026-08-29d
while Cargo.toml pins formats-pin-2026-08-30, so it would have expired on a tag
this tree does not use.
The real reasons are per-screen and already documented: title is the ptloop sweep
phase residual, title_jp is the --pose=rest sparkle handling -- where the port's
shipped pose scores +0.9994 against the game to the reference's +0.8727, so the
port is closer to the game on the row the script calls a disagreement.
Replaced with a named set: title and title_jp by name, any other DIFFERS fails.
A count cannot notice a different screen drifting while the total stays at two.
Controlled both directions -- passes on the known pair, fails on main_menu or
extras. The pin reminder now reads the tag out of Cargo.toml so it cannot drift.

First end-to-end pass I have actually seen: all six asserting checks ok, oracle
captures at 0.00-0.35%, verify-screen's 2 DIFFERS allowed for its stated reason.
My two earlier attempts produced nothing -- one killed by my own timeout with
block-buffered output, one wedged by the ffmpeg hang -- while I reported 'still
two lines, both ok' for three iterations. I was treating absence of output as
patience.
Their discriminating test holds, prediction written down first: incoming build 4
gives an 8-frame decay, build 5 a 5-frame one against my predicted 6. Their tell
reproduces from my export independently -- main_menu settled is [64], title's
opening pair is [255,64], composite [64,255,64], and no single element produces
it.
The consequence neither of us predicted: A title->menu is sequential with a real
~5-frame black interval, B menu->title has NO black interval -- the incoming title
draws at frame 34, before the outgoing quad ramps at 40. boot.gd applies
black_hold uniformly, so the port inserts ~9 units of black on B that the game
does not have.
Not changed. One run of one transition is exactly the generalisation they just
named as the error under two of their own wrong readings, and their second caution
is that the A figure may be a load rather than a designed hold. Recorded as a
known, stated divergence with a BLOCKED ask.

check-all sat on two lines of output for over an hour. The cause was the 5.1 bed
in check-capture-controls: ffmpeg completes the filter graph and then never exits.
Diagnosed rather than guessed -- the output reaches 4604262 bytes, exactly 8.0 s
of 5.1ch/16-bit/48kHz, the full intended length, with the artifact correct on disk
while the process hangs.
Three formulations all hang and all produce byte-identical output: the original,
one with -t 8 bounding the output, and one with explicit asplit feeding each atrim
(the textbook fix for multi-use of a single input). So it is not the split, not
the output stage, and the artifact is not in doubt.
Worse than the hang: it leaks. An orphaned ffmpeg from this script's earlier aloop
form was still running after 9.5 hours, burning CPU across runs nobody was
watching. boot.gd's header already names the shape -- a job that waits forever
reads as a job still working.
Bounded with timeout, and the ARTIFACT is now checked rather than the exit code:
the bed's duration must be 8 s or the sweep refuses to score itself. That is the
better test regardless of the hang -- an exit code says ffmpeg thought it was
done, the file says what it wrote. The step now completes in 99 s and the sweep
matches its specification.

The Decoder declined to let their measurement confirm my black_hold_units, and
they are right. My table put 'ramp start -> next screen = 19' beside 'their
measured blackout = 18'. Theirs runs content-start -> fully-black; mine runs
ramp-start -> next screen. Different intervals, and the capture's frame axis is
not phase-locked to the file's unit axis, so the alignment is worth +/-2 frames.
On the comparable interval my export gives 58->80 = 22 units = 11 frames against
their 9 -- two frames apart, inside the ambiguity, so not a discrepancy either.
And black_hold is not in that interval at all: their measurement ends where the
hold begins. It neither confirms nor refutes the 9.
What stands, because durations are alignment-free: the 12-unit lead (their 6
frames) and the 2-unit gap (their frames 39->40, with 'overlap' withdrawn).
9 now sits as authored-and-consistent, not confirmed-by-measurement.
Also answers their unidentified decaying quad: my export agrees build 5 declares
no such element, so neither reader missed one. Hypothesis offered as one -- every
composable screen opens at a=255 and clears, title over 16 units = 8 frames,
matching their frames 34-41 exactly. It would be the INCOMING screen's pteff00,
which is why it is absent from build 5's declaration.

Two warnings. The first does not reach me: nothing is authored from
screen-transitions.md's 0.87/0.97/4.08 s spans, and nothing in this port reads
keyframe times outside the crate -- their stale fade_quads.py failure mode cannot
occur here by construction.
The second is about black_hold_units: 9. Testing their structural claim on my
export: pteff00 on main_menu is [0:a255 12:a0 70:a0 80:a255], rising to black over
70->80, while content fade-outs start at 58-60. That is 12 units of lead, exactly
six frames at 30 Hz, matching their measurement off the running game -- disc and
capture agreeing by independent routes. They say the two overlap; mine has a
2-unit gap, one frame, inside their stated resolution.
The arithmetic: quad ramp 10 units + my authored 9 = 19 units = 0.317 s against
their measured blackout of 18 units = 0.30 s. One unit apart, inside their own
resolution. The measurement that withdrew the 14 supports my 9.
It survived because I declined to author the 14 when the arithmetic was available
and fit -- I wrote that it was arithmetic rather than a measurement and left the
value where it had been measured. Had I adopted the composition I would now carry
24 units against a measured 18, which is the dead black they are warning about.
Not adjusting 9; one transition, one run, +/-1 frame.

The Decoder found the ordinal/entry divergence is disc-wide (21 of 24 archives, 18
at ordinal 0) and that GP_TITLE is the mildest case on the disc, the only archive
whose first ten ordinals are the identity. That is luck, not design.
No exposure here, checked: the four archives they flag appear in flow.json with no
numbers at all, screen_names.json already says LOCATED BY ENTRY INDEX, and every
tool of mine passes --all.
Verified the high ordinals where GP_TITLE's identity would break first, since my
export addresses 13 and 14: publisher twins 10 vs 13 at RMSE 3.06, developer twins
11 vs 14 at 4.33, against a control of 47.91 for two genuinely different screens.
The addressing lands where HANDOFF says the entries are, and the control shows a
mismatch would have been caught.
The constraint is recorded for whoever exports those four archives; the absence of
exposure is a fact about what I have exported, not a property of the tooling.
Also corrects my own wording: I called ptlogo_all_eff a '50% glow'. What is
measured is the plateau -- that it is a glow rests on kind 0x3000 and a 200% scale
that nobody has put in front of the running game. The mid-ramp correction stands
on the numbers alone.

Width and mid-ramp predicted identically across my five capture-backed screens, so
I looked for a screen among the sixteen that breaks the tie -- either would turn
'confounded' into a minimal capture request.
The first run said title_jp was exactly that: window 46 with one mid-ramp element,
and I have the Decoder's capture of it. Wrong. The element is ptlogo_all_eff,
[0:a0 76:a0 112:a127 246:a127 258:a0], which HOLDS 127 from t=112 to t=246. My
test was 0<alpha<255, which counts any legitimately semi-transparent element as
mid-ramp, when the mechanism is about being caught in transition.
Corrected to: t falls strictly inside a segment whose endpoints differ. title_jp
goes to 0, main_menu and extras from 2 to 1 (pteff10 was a false positive
alongside the genuine ptmsg). The 5/5 result survives -- non-zero exactly where
the settle pose loses.
No separating case exists anywhere in the export: no wide window with a mid-ramp
element, no narrow window without one. The confound is structural across the whole
corpus, so no capture would separate the hypotheses from my side. They may be the
same phenomenon twice -- a narrow window is by construction one that closes while
things are still moving.

screen list maps [10] to entry 12, and the splashes are entries 10 and 11 -- so
their splash rows rendered the loading screens against splash captures. My own
HANDOFF entry had warned that this names the splashes as loading screens 'and
everything still validates'.
verify-screen's header claims --all protects me from exactly this, and a comment
claiming protection is what just failed on their side, so I measured it: my
reference for build 10 scores RMSE 8.97 against the publisher splash capture and
build 11 scores 8.77 against the developer one, with a cross-control (publisher
reference vs developer capture) at 48.17 -- 5.4x worse, so the discriminator has
teeth. The addressing is correct and now measured rather than asserted.
Worth the time because these two screens' 0.01% figures are among the strongest
evidence in the corpus and are cited in the rest() adjudication a proposal against
a pinned crate now rests on.
Their retraction confirms 190 and 145. Width and mid-ramp remain perfectly
confounded across every screen either of us has measured; my 5/5 predictor result
stands as a hypothesis about the mechanism, not as evidence over width.

The Decoder concluded width does not predict settle-pose quality but my
transient-peak/late-arrival predictor does, on the grounds that the splashes are
narrower than the menu (window 8) and win by 75x.
The predictor holds 5 of 5 on my capture-backed screens: mid-ramp count is 2 on
exactly the two screens where settle loses and 0 on the three where it wins.
But their splash window disagrees with my export by 20x. Recomputed from raw
top-level keyframe times, publisher_logo is [0,15,30,45,235,239,251,255] whose
widest gap is 45->235 = 190; developer_logos gives 145. We agree exactly on title
(76) and main_menu (12), so the divergence is specific to the splashes.
Consequence: the splashes are the WIDEST of my five, not the narrowest, so width
and mid-ramp predict identically and are perfectly confounded across my screens.
The case that separated them evaporates -- my predictor is not established as
better than width by this evidence, which is a different claim from being wrong.
My numbers also make their own census coherent: at window 8 the splashes would sit
in the 40.9% bucket while showing zero mid-ramp elements, a paradox; at 190/145
they sit in the wide bucket where zero is what the census predicts.

Their symmetry-breaking property is testable on the two screens my earlier table
marked confounded, and it turns up a class where their candidate loses.
ptmsg is [0:a0 44:a0 56:a255 58:a255 64:a0] and main_menu's settle window is
[44,56] with instant 50 -- so the footer is at alpha 127.5, half-drawn, at the
instant their candidate poses everything. Same on extras. The settle instant is
the midpoint of the longest keyframe-free interval, and on both menus that
interval ends exactly as the footer starts to arrive.
Measured with focus absent from both sides so the earlier confound cancels: t=50
gives 0.30% differing, t=58 (the footer's own hold) gives 0.25%.
Small and real. It does not overturn the proposal, which wins 9x-75x where rest()
returns a transient's peak. It identifies a failure mode of its own: an element
arriving after the settle window closes is caught mid-fade. Both poses are
approximations to a settled screen; neither is the settled screen.
Also: my first run asked --time=50 meaning units and got 50 SECONDS, past the end
of everything. Both poses returned RMSE 56.02 / 9.15%, identical to two decimals,
which is what made me look -- two different inputs giving the same output is the
instrument saying it ignored the input.

--boot --capture= used to write no file: _finish_boot() was reachable only from
the overlay-quit branch, and the boot quit first because that branch fires when
_overlay_spec.is_empty(), which it is the instant the overlay is raised. Fixed
earlier this session by the _overlay_quit_at guard -- and I never went back to
check what the fix made possible. The P3/P7 artifact has been available for hours
and unused.
The boot running unattended and photographing its own end state: RMSE 12.80,
0.00% differing against live-title-press-a.png. The residual is the known capture
gamma floor.
More useful: verify-capture reaches this frame by a shortcut (--screen=title
--overlay=press_start --time=3.95) rather than by booting, and that shortcut has
been trusted since it was written and never tested against what it stands in for.
It is faithful -- 12.83 / 0.00% against the boot path's 12.80 / 0.00%, agreeing to
0.03 RMSE.
Does not show the intervening sequence is right: it is one frame, the last one.

They proposed posing at the screen's settle instant, found their control could not
validate it (a candidate cannot be adjudicated against the incumbent it replaces),
and said the oracle number decides. I had only run it on one screen.
Three screens adjudicate cleanly and all favour the candidate: title 0.21% vs
1.82%, publisher_logo 0.01% vs 0.75%, developer_logos 0.01% vs 0.33%. The settled
figures match verify-capture's independently recorded numbers to the digit.
Two rows are not evidence. My first table had main_menu at 3.29% for the
candidate, losing by 13x -- the opposite direction from everything else, with no
plausible story. --screen= shoots immediately, so that render drew 6 of 16
elements and skipped ptframe1, ptframe2 and ptmsg as transparent at t=9. The same
wrong-frame error as title_jp, caught before publishing only because the
direction made no sense.
Posing them properly needs --menu, which also draws the focus record, while the
rest column draws none. verify-capture's header records main_menu without focus at
2159 px = 0.234%, and my incumbent figure is 0.25% -- so the entire gap on those
two rows is the focus record, not the pose. Marked confounded rather than counted;
a 5-0 was available by not looking.
Does not validate their implementation: I tested the port's settled pose, not
UiBuild::settle_time().

Their surviving number needs no threshold: the dwell fallback runs only when no
two adjacent poses are equal, so every pose it returns is un-held by construction.
The obvious move was to replace my 'gone before 60% of the screen' cutoff with how
long the rest pose is held.
It flags ptmsg (the main menu's footer, 2 units of 80) and ptbtn00 (the plate, 2
of 244) alongside the real sparkle (2 of 269). All three sit on a 2-unit plateau,
so hold duration cannot separate them -- and the two it gets wrong are the exact
pair whose absurdity caught my first census.
The criterion does not transfer because on the fallback path nothing is held, so
un-held IS the defect, while on the plateau path the plateau is real and what
distinguishes a footer from a sparkle is where it sits relative to the screen's
end. The screen-span criterion stays.

verify-screen's header has said since P1 that build_12/build_15 render pure black
in both renderers, with an open question whether that was the port's bug or the
decoders' reading of rest. Measured today: max 214.5 on both sides, mean 1.949
port against 1.918 reference. Not blank, and they agree.
It was the paint order. My own earlier measurement had already answered it and I
had not connected them: removing the forced-backdrop pass makes the first element
pgloading_loop5 and the black screen returns. pgloading_eff00 carries layer: null,
layer_source: none -- the only elements in the export with neither a read nor an
implied key -- so its position rests entirely on the occlusion constraint.
The guard stays, with the stale paragraph kept as history. It was right when
written, and a guard that stops firing is the kind that rots out of a tool.
Refutation attempt on the Decoder's census scope: my six transient
ptlogo_back2eff* on title are also GP_TITLE, so if they were fallback fires their
count of four would be wrong. Their claim survives -- all six reach rest by the
plateau path, alpha 255->255 with identical pos and scale, so the fallback never
runs. The two censuses differ in scope, not in fact.

Claude-Session: https://claude.ai/code/session_01N7FiFFFwbvG2uxdcEh8HyF
The Decoder refuted my refinement: palogo_gamearts_eff/palogo_seta_eff hold a=255
at identical x, y and scale from t=15 to t=30, so that is a genuine plateau,
rest_plateau() handles it, and t=15 is correct for that path. They are not among
their four.
The consequence strengthens the rule rather than retracting it: my rest pose for
them really is the flash's peak, reached by the SOUND path -- so 'a rest render is
not a frame to score against a capture' does not depend on the fallback being
unsound. A plateau can itself be the held peak of a transient, and their census
understates exposure rather than bounding it.
Censused my own tree. The first answer, 28 elements across 12 screens, was wrong:
it counted the screen's exit ramp as the end of visibility, so ptmsg -- the main
menu's own footer -- and ptbtn00, the plate, came back as transients. No control
would have caught that; the arithmetic was right. What caught it was saying what
the number meant physically.
Re-keyed on the screen's span: 31 elements across 8 of 16 screens, all of them
eff/loop sparkles or the two loading screens, with ptmsg and ptbtn00 falling out
on their own. Exposure is twice what the splash finding suggested. None of it
reaches shipped output.

The Decoder censused rest()'s dwell fallback from the file side: 2305 elements
have no plateau, 1697 of those get a visible pose, and in GP_TITLE all four
visible fires are on the splash screens this port ships. Confirmed in my export.
Refinement to their description: they named the [0:a0 15:a255 30:a212 45:a0]
shape, but palogo_gamearts_eff and palogo_seta_eff hold 255 through t=30, so
their fallback lands on the flash PEAK rather than its decay. Same defect, worse
pose.
The port ships the right frame and there is now a number for it. Publisher splash
against the committed oracle capture: timeline (shipped) RMSE 2.17 / 0.01%
differing; --pose=rest 9.05 / 0.75% -- 75x the differing area on a screen I ship.
So the rule added to verify-screen's header after the title_jp mistake
generalises, and is demonstrated against an oracle rather than argued.
What did need fixing: ScreenView logged '(transparent at rest)' for every skipped
element whatever instant it posed, so it said that about palogo_sqex_eff, whose
resting alpha is 212. That is the same rest-versus-posed-instant confusion that
cost a wrong conclusion, pre-printed in the log. It now names the instant.
Controlled both ways: timeline says 'at t=6' and skips the flash, --pose=rest
still says 'at rest' and draws it.

The previous entry scored verify-screen's title_jp frame against the oracle and
concluded the port had moved away from the game. That frame is posed --pose=rest,
which the port does not ship. Posed as it runs, the disputed block scores +0.9994
against the reference's +0.8727, and the whole surface +0.9652 against +0.9200 --
holding under gamma compensation and on the English control (+0.9946 vs +0.9560).
The port is closer to the game than the reference on both title screens.
Mechanism: ptlogo_back2eff1 is (0,0)(98,0)(100,255)(102,255)(104,0) -- a 4-unit
sparkle whose rest.t is the peak of its own flash. Six of them stagger across the
logo, so --pose=rest fires every sparkle at once. The 25.6% excess light was real
and was in a frame nobody sees.
verify-screen is not at fault: it poses rest deliberately, so that both renderers
read one decoder and the run is a consistency check. I used a consistency-check
frame for a correctness question. Its header now says its frames must never be
scored against a capture.
A second claim in that entry was also wrong -- both screens draw those layers
under pose=rest; I had compared a --menu timeline log against a verify-screen
rest log and read a mode difference as a screen difference.
verify-capture takes a fifth per-row field, a capture crop, because this capture
is a full display frame with the surface at +0+45 while the others are
pre-cropped. With it title_jp reads RMSE 20.91 / 1.04%, beside title's 14.16 /
0.21%. The row prints 'no capture' until their branch merges.

The Decoder captured the Japanese title at rest (310bf86) without comparing it to
either renderer, keeping my diff independent.
Alignment recovered, not inherited: row/column profile correlation with the
English pair as control gives (0,0) for the control and dy=-45 for the JP frame --
their stated offset, measured. My first look said 'no letterbox, content spans all
720 rows', which was true and irrelevant.
The instrument is fair: on a control strip where both renderers agree they tie
(r 0.9751 vs 0.9756). In the disputed 350x396 block at (405,74) the REFERENCE is
closer -- r +0.8727 against the port's +0.7462 -- and the verdict is stable under
gamma compensation at both measured title gammas. The port puts light on 25.6% of
the block the capture does not have, against the reference's 15.9%.
This is the opposite of what I expected: the burst the Decoder describes IS
there, and the port draws more of it than the game does. A qualitative match on
'is the effect present' was about to stand in for a measurement of how much.
Not settled: which change did it. Both render at rest t=10 so the settle window is
not in play; four commits touched that path and I have not bisected them.
title_jp's DIFFERS is now known to be the port's -- the first baseline row whose
direction has been established against a capture.

Running the full set after the plate fix, press_start returned over3 5021, 8919,
5021 on three identical runs. The plate's looping focus record takes its phase
from time_units, which free-runs, so the captured frame lands wherever the grab
fell -- while the reference renderer cannot pulse at all.
The port is not the thing that is wrong: the pulse is measured and a thing that
pulses does not stop because the screen arrived. ScreenView.loop_phase_units pins
it, negative means free-running and stays the default everywhere, and only the
harness passes --loop-phase=0.
Controlled: pinned, 3 runs identical; free-running, 3 of 4 identical and one
different. That 3-of-4 is why it survived -- it looks deterministic most of the
time, and without the negative control a no-op flag would have been
indistinguishable from a fix.
With the phase pinned press_start reads max 1 / over3 0 OK -- the recorded
baseline exactly. Fifteen of sixteen rows now match.
The sixteenth, title_jp, has genuinely drifted: 155/20498 -> 233/61208,
deterministic, on the Godot side, localized to one 350x396 block at (405,74).
There is no capture of the Japanese title, so I can say the renderers moved apart
but not which moved. Recorded as an ask, not resolved.

The Decoder measured that after B from the menu the plate is re-drawn (daf8f47).
The port landed on a BARE title: _menu_arrive drops the overlay -- correct, the
plate goes with the screen it was measured on -- but nothing put it back, since
_overlay_spec is cleared the instant the overlay is raised and only the boot
sequence ever set it. Confirmed by running it: ten title elements, no ptbtn00.
_rearm_overlay_for reads the declaration out of authored/flow.json's boot step
for that screen rather than naming press_start, so the plate returns by the same
path and shared clock as on boot, with NO new constant. Controlled both ways:
cancel raises it, entering EXTRAS (no overlay declared) raises nothing.
Script steps now carry an elapsed timestamp, without which the port's own press
latency could not be compared to a measured one. With it: B at 1.01 s, title at
1.37 s = 0.36 s, against their measured <= 0.4 s -- nothing was fitted to that.
The plate's RETURN time does not agree: 4.33 s here against their 7.3 s to pulse,
of which up to 2 s is pulse-detection phase. Not adjusted -- an authored delay in
this same block was already refuted once. Recorded as an ask.
auto_repeat and title/on_cancel upgraded to MEASURED on their run.

Rows 1 and 2 were still labelled '(P3, blocking)' while P3-P7 have all shipped.
Audited all five against HANDOFF and checked whether the port ACTED on each
answer: splash by entry index (publisher_logo 10/13 exported), focus ring
ptbtneff01 drawn, rotation about pos+pivot, gamma floor in verify-capture's
header. Four struck, one (rotation) still a human decision.
HANDOFF ask 2 tells the port to author a ~24-unit fade constant. That is stale:
the corrected record layout leaves no untimed keyframe, and measuring what the
file carries shows the black quad ramping 0->255 over TEN units. Authoring 24 on
top of it would run the fade 2.4x too long. The mechanism ask 2 describes is
confirmed in the file; its number is not.
Offered as a hypothesis, not a finding: in-file ramp 10 + measured hold 10-14 =
20-24 units = 0.33-0.40 s, bracketing the measured 0.4 s at the top -- so the
0.4 s may be ramp + hold, needing no constant at all.
Also surfaces a disagreement in my own tree: black_hold_units 9 (0.15 s) sits
below HANDOFF's measured 0.17-0.23 s plateau. Not changed; recorded as an ask.

The Decoder measured B on the main menu -> title (86a8ce7): delivery-confirmed,
<= 0.4 s, no loading screen. main_menu/on_cancel moves from 'likely but UNPROVEN'
to MEASURED -- and it is the LATENCY that settles it, not the destination: my own
why had named the confound that the title also auto-returns after ~8-10 s idle,
and 0.4 s is twenty times faster than that.
The other half is a fault in my tree. title/on_cancel_why read 'MEASURED,
HANDOFF Q5'; the source's evidence cell for that clause reads 'none'. HANDOFF Q5
prefixes a six-clause row with one **measured** and my authored tree copied the
word. The value stays null either way, so no pixel moves -- what is removed is a
false provenance.
Auditing the rest of that row rather than only the clause I was handed: the
up/down cell is ALSO empty. It splits -- one-item-per-press is carried indirectly
by the wrap montage's count, no-auto-repeat is not. The port already behaved this
way without stating it (edge-triggered _input), so navigation.auto_repeat is now
explicit and marked a choice.
34 MEASURED stamps audited; six cite a HANDOFF row alone, one of which was wrong.

The Decoder found that sylpheed-cli screen render silently omits the background
of any .tbm-bearing build, and stated that none of my screens has one. That is a
claim about my tree and it decides whether my regression baseline is sound, so I
tested it: zero .tbm across all 16 builds in my manifest -- wider than the five
they said. Both controls fired (GP_TUTORIAL build 0 -> pubase.tbm; GP_TITLE
build 5 -> none); my first attempt's control printed nothing and I nearly read
that as agreement.
verify-screen now names the omission on any .tbm-bearing row. It cannot fire on
a screen I ship -- which is how a guard goes dead -- so its expression is
controlled directly in both directions. No verdict or bar changes.
Regression unchanged: title max 6 / over3 790, main_menu max 4 / over3 0.
Their identification (reading TUTORIAL off the framebuffer) and my edge
correlation (run before their message, blind to the text) agree on GP_TUTORIAL
build 0 from no shared assumption.

They reached a submenu and could not identify it: intensity correlation cannot
discriminate when the candidates are near-blank, which is what the .tbm hypothesis
predicts. Their capture is 99.999% non-black -- a full-screen background our
renderer omits -- and an additive background swamps intensity but not edges.
Control first: edge correlation against my own title capture over seven GP_TITLE
builds picks build 4 at +0.2792, 1.4x over second and 7.6x over third.
Result: GP_TUTORIAL build 0 at +0.4962, build 1 at +0.3137, best GP_SAVE_LOAD at
+0.0713. Winning r higher than the control's and margin better; both TUTORIAL
builds 4-7x above every SAVE_LOAD build. Independently plausible -- flow.json has
ptbtn03 = TUTORIAL -> TUTORIAL_MENU, not a GP_TITLE build.
The ARCHIVE is identified with a large margin; WHICH BUILD is not -- 1.58x is the
same order as the control's 1.4x and the two are variants of one screen.

Every asserting check passes and the oracle rows are at the tone floor:
title_plate 0.00%, both splashes 0.01%, up to title_band 0.35% against its own
oracle-to-oracle gap. The P5 walk runs and ends on the title.
The refutation attempt was of a claim I had already used: that ADV.wmv carries one
audio stream and it is WMA Pro 5.1, which reframed the whole voice question.
ffprobe confirms it exactly -- one stream, wmapro, 6 channels, 5.1.
And I had built on it for a week without running it. The positional weights, the
presentation: all change, the refusal to apply the assignment when byte sizes did
not fit -- all rest on that reframing, verifiable in one command against a file I
have had throughout. I audited the byte sizes scrupulously because they were the
identifier I could test, and never checked the sentence the identifier served.
A premise so foundational that everything downstream got audited and the premise
did not. The scrutiny went to the parts that moved.

The Decoder's audit of their own corpus found four refuted claims standing --
including one they had corrected to me, agreed with, and written a METHOD entry
about, without landing it for a full iteration. A hand audit finds what is there
on the day it runs; it does not stop the next one.
check-claims is a register: every occurrence of a refuted claim must carry an
explicit [refuted] sentinel within 400 characters. It found four more unmarked
occurrences than my manual pass had, including one in authored/audio.json.
The marker is a sentinel rather than a keyword because the first version's every
failure was a quotation inside a correction whose wording lacked the keyword. The
temptation was to widen the window until they passed -- tuning a threshold until
the answer comes out right, in the tool built to catch that. 21 quotations marked
by hand; proved it fails by removing one.

Applying the Decoder's rule to my own corpus, on four claims refuted this
fortnight. Two were properly marked. Two were not.
The exported why still told readers the dropped chunk 'IS understood: the TAIL of
the kept stream' -- an interpretation refuted when the resolver turned out to
start 238 packets inside the first stream, so what matched end-flush was a
start-truncated simultaneous stream. It was wrong twice over: S00A's dropped
chunk is the SILENT one, so the sentence described a case that was not present --
the second template-message-true-only-for-one-case defect in this file, which
suggests the first fix taught me nothing general.
'The port's boot is known too fast on both' was still standing unmarked. I wrote
the withdrawal as a new section and left the original untouched, so a reader
arriving there first got the dead answer. Annotated in place.
One false positive: BLOCKED matched inside my own correction, which quotes the
refuted claim to name it. Naming a refuted sentence keeps it greppable, which is
the price of not deleting it, so the audit needs a read of every hit.

Region [9.44, 71.31] of an 87.744 s wave: first 9.44 s an intro played once, last
16.4 s a fade never played. 61.87 replaces 61.93, 0.1 percent apart; the measured
value has the loop's own endpoints under it.
The port's near-silence count tracked the window's correctness without being
designed to: 36 frames spanning 3.4 s untrimmed, 5 with the right length over the
wrong window, 0 with the measured window. The old window kept part of the quiet
intro; the measured one excludes intro and fade both. Wrap continuity is
unchanged and still not evidence -- the silence count discriminated where the
step count could not.
Also fixes a stale why that reached the manifest for two days: corrections went
into loop_end_why and loop_start_why while loop_why, the field the exporter
concatenates, still said the loop would be audibly wrong at the seam and that no
loop-point field existed. A correction that does not reach the artifact a
consumer reads has not been made.
My first check of that fix reported the stale text still present, because the

loop_start, both contexts wrapping at the same instant. Cycle 61.81 s against the
61.93 authored here: 0.2 percent, from a wall clock between decoder events versus
an autocorrelation that never touched the wave.
The window is wrong: loop_start is 11.6 percent into the stream, about ten
seconds, so this export has the right duration over the wrong window -- replaying
the intro every cycle and omitting the tail the game plays.
Not re-cut, on their instruction: the exact start is unmeasured and linearity is
refuted by a 4.4 percent rate variation within one stream. But loop_end_s alone
silently asserted a start of zero, so the entry gains loop_start_s, authored as
0.0 and flagged wrong, with -ss applied before -t so the pair is (start,
duration). Proved before it is needed: loop_start_s=10 yields -ss 10 -t 61.93 and
a 61.930 s output. Restored to 0.0, export byte-unchanged.
My smooth-join check gains a use I could not have anticipated: it explains why a
wrong ten-second window went unheard, because a cut near a zero crossing is
smooth wherever it falls.

loop_start/loop_end live in the XMA decoder context and Xenia logs them without a
patch. Converted they imply roughly [10 s, 72 s] against the [0.25, 57.18] their
audio tracking gave. Neither withdrawn. Two of their own predictions were refuted
by the data -- loop_start is 11.6% in, not ~0, and a linear bits-to-seconds
conversion gives 62.34 and 63.29 s for two stems that must be sample-synchronous.
The port KEEPS loop_end_s: 61.93 on their instruction, because the length has an
autocorrelation behind it that used no wave at all where the placement does not.
Adds one check neither instrument ran: over 126.5 s the wrap shows a max
adjacent-sample step of 212 and 208 against a 99.9th percentile of 3737, so the
join is not a click. Explicitly NOT support for 61.93 over [10,72] -- a cut near a
zero crossing is smooth wherever it falls.
Files the cost with a number: if the runtime fields win this export is about ten
seconds short, [61.93, 72] being content the game plays and we omit.

Their census settles the population at 25 three-chunk regions, confirming my
count, and corrects their own claim twice: multichannel-specificity holds (17 of
17 changed are three-chunk), but 'all three-chunk regions were broken' is false --
8 of 25 were already fine.
Measured every three-chunk region's span myself: the 8 unaffected run 71680 ..
1400832 B, the 17 affected run 2023424 .. 6516736 B. The cap separates them
exactly with a 622592 B gap between the sets, so this confirms the MECHANISM --
a byte-size threshold -- not just the list of names.
My first run reported 17 contradictions: every span read 0 B because awk took the
trailing 'B' rather than the number. Uniform, consistent and entirely wrong, and
it would have looked strong because the failure fell along the line under test. A
broken extractor produces a pattern shaped by the question. What saved it was the
8 confirming rows reading 0 B too -- visible only by reading the half that agrees
as carefully as the half that does not.

Two iterations ago verify-menu-audio's bit-identity assertion began failing and I
filed three suspects in the port. It is none of them. Three IDENTICAL invocations
give two outcomes, 1.207438 s and 1.300317 s, differing by exactly 4096 samples --
one mixing buffer. The recording quantises to whole buffers and a one-buffer shift
moves the length and alignment of everything in it.
The premise -- cross-run bit-determinism -- was never guaranteed. It held while
timing sat away from a buffer boundary, and a larger export moved it onto one. A
test that passes by luck reports the luck running out as a regression in the code,
which is what it did: two iterations of suspects, and the port was never involved.
The fix keeps exact equality and no threshold, allowing the comparison to slide by
whole buffers -- the one degree of freedom the recorder has. Proved it can still
fail: ctrl against walk differs at every alignment.
Distinct from the earlier entries: this check ran and answered the right question,
resting on a property of the environment nothing verified. State what an assertion
assumes about the machine, not only what it checks.

Measured on 240 s parked on the real menu: no seam at all (zero runs >=0.3 s
below median-18 dB in 232 s), and the loop is at 61.93 s, not the summed wave's
87.744 s length. Two instruments agree -- top correlation lag 61.909 s with
r=-0.009 at 87.750, and slice location showing playback wrap at 61.93 three
times. The final ~25.8 s, the fade-out and trailing silence, is never played.
This port had authored loop: restart, measured the resulting 3.4 s of
near-silence off its own Master bus, and reported it as the price of the missing
loop point -- in BLOCKED and in a message to the Decoder. The measurement was
correct and the attribution was wrong. Second time this fortnight I have measured
something real and assigned it to the wrong side.
Godot loops whole files, so the loop region has to BE the file: BgmSpec gains
loop_end_s and the bed is trimmed to 61.930 s. Verified over 131 s on the port's
own bus -- 5 near-silent windows, no run >=0.2 s, against 36 windows and 3.4 s.
Also records their withdrawal of '8 of 10 three-chunk regions': that audit file
was truncated mid-list with no summary line, so the multichannel-specificity
claim is unsupported and my 25 stands.

The Decoder has no external check on the regions beyond ADV. One reference owes
nothing to their crate: each movie's own duration from its WMV. A start-truncated
stream must decode shorter than its movie -- ADV's was 38% short before the fix.
Dumped every region and decoded every chunk: 25 three-chunk regions, 75 chunks, 0
more than 5% short, largest deviation 1.78%. No region is still truncated, and
the reference is genuinely external.
Flags a population discrepancy: their page says 8 of 10 three-chunk regions start
mid-stream; I find 25 three-chunk regions on this disc. Reported, not resolved.
My first run reported '0 of 13' and there were 25 -- cargo run inside a while
read loop consumes stdin, so every second movie was eaten and the covered set was
positions 1,3,5,7... The result was correct for what it measured and the
population was half what the sentence implied. That is the truncated-log trap
arriving in my own shell loop; I caught it only by comparing against a count from
one command earlier.

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.

The late start was a second condition on the start filter, end - s < 1_500_000,
only within one bank. ADV's predecessor trailer sits 3618816 B before end, so it
was rejected and start fell back to anchor, a TOC offset rather than a stream
boundary -- which is why it hit regions over 1.5 MB and never single-stream ones.
ADV region 3114352 -> 3618816 B, streams 2 of 3 -> 3 of 3, complete, dropping
zero chunks. S00A 1 of 3 -> 2 of 3 with the third digitally silent. The runtime
no longer prints an incomplete line for either.
Also fixes the warning crying wolf: S00A still read KNOWN INCOMPLETE over a
93.694 s stream of exact zeroes. Exported gains content_waves and the warning,
console line and manifest field all key on kept < content rather than kept <
present. Second time in two iterations this warning was wrong in the cautious
direction -- over-warning is what makes the next real warning unreadable.
S00A is a second movie in the predicted direction: kept went 1 -> 2 because a
chunk that was a different duration now matches at 93.694 s. Not independent
ground truth, but a different asset and the outcome was predicted first.

The manifest has carried the gap for weeks and the runtime printed '+ voice ADV'
and nothing else. A reader of manifest.json gets a paragraph; a person LISTENING
gets clean dialogue and no way to learn a stream is absent. NEW GAME already
announces the screens it jumps over; audio had no equivalent.
ManifestAudio gains -- one line naming what is KNOWN missing, absent
meaning nothing is known rather than nothing is wrong -- and MenuAudio carries it
so _play_video can print it. Verified on the boot's ADV and P7's S00A.
The first version of the message was FALSE for one of the two assets: it said
'one is a start-truncated stream', which is ADV's story, where S00A's dropped
chunks are digitally silent. Caught by reading the output for both, which I
nearly skipped because the ADV line was obviously right. Now states the counts
and points at the entry's why.
A message generated once from a template but true only for the case it was
written against is harder to see than a wrong number -- the sentence is
well-formed and confident in both places.

My refusal to apply their weights found a defect in their decoder:
resolve_movie_voice_region starts 238 packets (487424 B) inside ctx0 for ADV, and
8 of 10 three-chunk regions start mid-stream disc-wide.
That re-reads one of my own measurements without touching it. I had the leading
chunk as 'the TAIL of the kept stream' at r=0.998, lag flush against the end, and
dropped it as a duplicate. If the streams are simultaneous and the region starts
238 packets into ctx0, the surviving fragment is ctx0's later 62%, which aligns
flush against the end -- exactly what I measured. Same number, opposite meaning:
a start-truncated simultaneous stream, not a duplicate. The port drops a real one.
I suspected the instrument first, since they had just shown envelope correlation
saturating at 0.86-0.95 across stream/channel pairs. Tested on the dialogue: r =
1.0000 at zero offset, -0.08..+0.08 elsewhere. It localises sharply; their
saturation is concurrent streams at zero lag, a different regime. So the tool was
sound and the error was entirely in the inference.
Not fixed: including chunk 0 needs their corrected span (they say do not extend
blind -- only ADV's clip is known) or an alignment decision I would be inventing,
since the chunk is missing its head.
