--screen=X animates X but froze an overlaid Y -- my earlier fix overshooting,
replacing a frozen-too-early overlay with a frozen-at-arrival one. The plate
pulse made it visible: oscillating on the boot path, flat here. Now offset, not
pinned: the overlay starts at its settle and takes the main view's delta. Static
path now pulses 95.85 -> 115.41 against the boot's 95.68 -> 115.52; still frames
unaffected and title_plate holds at 0.00%.
Both halves were mine a week apart, and the over-correction was invisible until a
third change gave it something to be wrong about.
Refutation attempt on their pulse floor: 159/714/1520 is NOT reproducible from
the published description. My counts on the same capture are 3-5x theirs at every
threshold, so their region must be a tighter crop; neither region nor threshold
is stated. The RATIO survives robustly -- 1:10.4-10.9 across a wide band,
bracketing their 1:9.6 -- so 'steady base plus pulsing glow' stands, which is all
the port's implementation rests on.

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.

The Decoder lost a finding whose only record was a script comment and asked
whether I have the same. Audited every measurement-shaped token in comments
across the exporter, the GDScript and the tools against everything in docs/.
Seven candidates, six were my matcher (thousands separators, ranges written
differently, precision). The findings are all in DECISIONS, including the leaf
comment's capture-measured centres and the 11.5 px residual.
The one real defect is the opposite: check-capture's control table and
AUDIO-VERIFICATION.md had DRIFTED -- 53.3% against 53.2%, twice each, for one
control whose file is gone so neither can be re-measured. They lost a finding to
having one record; I lost a digit to having two with nothing keeping them equal.
Fixed by citing rather than restating.
Also corrects a message: I told them my computation reproduces their published
centres to half a pixel. True, and MODEL against MODEL -- against the capture
this corpus already records 992.0/467.2, an 11.5 px residual. The half-pixel
agreement is two derivations of one model, the correlated-instrument shape I have
been careful about all week and did not apply to my own message.

Ask #2 answered: t=357.7 was never fitted against a PNG. It is a GPU per-draw
vertex capture, four observables at once.
They handed me the discriminator rather than running it, since the fit is against
my renderer. At my t=400, pteff03a computes to 294.9 against their predicted 295,
and my computation reproduces their published t=355 control (980.5/477.7 against
981/478). So the two numbers describe different frames and neither is wrong.
Why they could never match: the leaves free-run at 600 and 720 units (verified
from my export as each leaf's last keyframe) while the top-level clock stops at
settle, so two captures of one settled title share a screen time and not a sweep
phase. A SWEEP POSITION CANNOT DATE A FRAME -- I had been treating my ~400 as a
property of the capture.
Also records their failed refutation of my number: they hypothesised the fit was
minimised by the quad leaving the screen, the same shape as their .tbm control
that could not fail. At t=400 quad B is fully on screen. It survives.

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.

Disc-wide: 0 read from the T8aD header, 14 implied, 66 nothing. So the rule has
never been checked against a decoded field because no instance lets both speak.
The port's six are the same pattern: 0 read, 4 implied, 2 nothing.
Records their retraction, which runs against their own interest: 'none of the 18
is evidence' conflated two questions. The rule does not CHANGE the composite on
those 14, but it does get the RIGHT ANSWER there, and implied_layer_key is a
position measured in the running game -- so those are the rule agreeing with the
oracle, its only external corroboration. Four of the 14 are the port's splashes.
My own framing was right about provenance and wrong about weight: I filed an
oracle measurement under 'not the file', which reads weaker when it is stronger.
Closing the thread on my side -- four iterations, and it has stopped being about
the port.

Their 49771 is exact RGBA inequality, not a threshold, so it belongs against my
59530 rather than my 48368 -- they corrected that before I could match the
convenient pair. At >1 we agree to 325 px (0.67%).
Checked here: my value-exactly-1 population is 11162 px and the gap above >1 is
325, so 9434 of the 9759-px gap (96.7%) is value-1 pixels. Their claim holds
structurally.
Carries two conventions: >0 is not portable between renderers on a mostly-dark
frame and >1 is, so a cross-renderer ink figure must name its threshold; and the
without-the-rule zero is threshold-insensitive in both renderers.
One refinement on their 18 confirmations: for the port's four, 'has its own key'
means palogo_eff0's IMPLIED key -- the crate's measured per-name entry, not file
data. So those are 'another measurement already settles it', not 'the file
settles it' -- the distinction their own page insists on for pteff00.

The Decoder rendered the 62 deciding builds twice and found changed pixels equal
the composite's entire ink on all 38 .prm deciders, with build_12/15 at 49771 px.
Checked in Godot, which shares no code with their compose: with the rule 59530 px
(>0) / 48368 (>1), WITHOUT it exactly 0 at both thresholds.
So the strong form holds -- removing the rule does not dim the screen, it takes
the ink to zero -- and this is a real second witness, unlike last iteration's
re-run of their own instrument. Their 49771 sits 2.9% above my >1 count: a
threshold convention on a mostly-dark frame, recorded so nobody later reconciles
two figures that were never counting the same pixels.
Method: applied THEIR fallback (sprite key, else implied, else u32::MAX) to the
export's element list and swapped only paint_order on one screen, so the renderer
and every other input are identical and the order is the only variable.
Also records their point 4 -- the 24 .tbm deciders measured zero because compose
draws no .tbm pixels at all, a control that could not fail. Fourteenth instance of
the shape, and the first caught by the other agent using the frame.

They published the instrument so it could be re-run rather than trusted. Ran it
from a worktree at their branch across all 33 archives: 80 forced, 62 decided, 18
agreed, 38 .prm / 24 .tbm, all 62 keyless. Every figure exact.
Names the limit: I ran THEIR code, so a fault in the instrument reproduces for me
too -- one measurement executed twice, not two measurements. The independent
evidence is my own export-side removal of the post-pass, which is different code
in a different language and agreed on the six GP_TITLE instances. So GP_TITLE has
two witnesses and the other 74 have one.
Also notes the example defaults to GP_TITLE and reports 6 unless given an archive
path, so 'I ran their instrument' would otherwise mean a thirteenth of what it
sounds like.

I have said 'six forced elements' since implementing it and verified after every
change that no verdict moved -- which measured stability, not necessity. Removing
the pass entirely: the four splashes are BYTE-IDENTICAL, because palogo_eff0's
implied key 0x00000000 is lower than the lowest sprite key and the crate already
sorts it first. Only build_12/15 change, and they go black again.
Those two are the port's strongest dependency on an undecoded rule:
pgloading_eff00 there has layer: null, layer_source: none -- the only elements in
the export with neither a read nor an implied key. Their position rests entirely
on the occlusion constraint with nothing to fall back on, and that was hiding
inside a count of six.
Census: 160 layer keys read from sprites, 16 implied (every layerless primitive),
2 absent. FORMAT.md requires a consumer to tell which, and layer_source does.

Every SendMessage since 2026-08-29 returned 'delivery is not confirmed'. I
recorded it in my reply every time and treated writing it down as dealing with
it. Twenty-one identical warnings.
Cause: I addressed the bridge session ID copied from an inbound message's from=
field. Session IDs die on restart; PROTOCOL.md says both agents register under
NAMES and shows SendMessage(to: 'sylpheed-agent'). The protocol had it.
Worst of the thirteen instances because this one had an alarm and the alarm fired
every time. The repo carried the findings, which is what let me treat a broken
channel as a non-event -- but it could not carry the ASKS, and four sat unasked
while I believed them queued.

Last iteration I filed title and title_jp's disagreement with sylpheed-cli as
mechanism-unknown, to the Decoder as well as here. Both were already explained in
this file, under headings that name the two screens.
Checked rather than assumed. title: still ties on 0x8083, 0x80a0 and 0x8010, and
the export declares paint_order_ties unresolved; the old entry's 904 px in the
glow band matches my 790 px at the same place, same 4-6/255 magnitude. title_jp:
the 'only non-integer scale' claim finds 26 keyframes export-wide, but exactly
ONE element visible at rest -- ptlogo_eff2 at 125% -- which is the pose
verify-screen uses. It survives narrowly.
The failure is navigability: 6502 lines, 111 sections, no index, so 'has this
been decided?' had no cheap answer and re-deriving it looked like diligence.
index-decisions generates the contents; check-all runs --check. No line numbers
(the first version was a fixpoint that failed its own check, and appends would
invalidate them all), and checked, because a stale index answers 'already
decided?' with a confident no.

The page warns it goes stale 'within the hour. It has.' Nothing audits it.
P3/P5 - the title screen was wrong in every factual claim: the boot does not end
on a plateless build 4, press_start is not unused, and the port has drawn two
builds at once for weeks. A row four lines below was already marked answered and
TAKEN for the same question -- two rows, one struck, and the LIVE one was stale.
P4 - skippable led with 'the port could not tell which bug that is'. It did:
DECISIONS records that (A) does skip in this build and every boot prints it.
P6 looping now carries the measured seam: 3.4 s of near-silence at 87.8 s.
The split is clean: every prose section added since 2026-08-29 records the
HANDOFF sha it derives from, every row in the two tables records none -- and all
three stale rows were in those tables. Not back-dated: an invented sha would make
an undated claim look checked. Both tables now say so and carry an audit date.

Two iterations ago I filed title's 790-pixel gap with sylpheed-cli as needing the
Decoder's element list. That was a hypothesis dressed as a question and it is
refuted: the pixels sit at ptlogo_back2eff1 (pos 938,194) and BOTH renderers draw
it -- mean 95.60 against 95.08. A set difference would have confirmed nothing at
someone else's cost.
Also ruled out: a placement offset. Every +/-1 px roll is two orders of magnitude
worse (790 against >=175406).
The mechanism stays unknown and I am not guessing. My antialiasing test failed
its own control -- the edge mask covered 92% of the frame, so the 25.2% of
differing pixels on it is below chance.
Ask withdrawn rather than left standing: a row on a refuted premise is worse than
no row. The residual is 0.086% of one frame between two of our own renderers, on
a screen matching the oracle at 0.21%.

Eleven tools and nothing ran them together -- the ninth instance of correct,
documented and unexercised, one level up. check-all runs the four that assert,
reports the oracle table, and gives verify-screen an allowance that EXPIRES when
the pin lands rather than standing forever. All eleven exercised first; none had
rotted.
verify-screen computed over3 because 'a single max cannot tell 2 pixels from
25 444' and then decided the verdict on max alone: main_menu (max 4, over3 0)
read DIFFERS while extras (max 3, over3 0) read OK. The bar is unchanged; a frame
with no pixel over it now gets its own ROUNDING verdict.
And corrects a claim I have given the Decoder more than once. The real count was
ten, now eight: six forced-backdrop, two rounding, and TWO UNEXPLAINED -- title
at 790 px and title_jp at 20498, neither carrying a forced element. My leaf
hypothesis is refuted: emptying draw_leaf_for changes the numbers not at all.

AUDIO-VERIFICATION.md calls its six-file sweep 'the tool's real specification'
and nothing ran it -- in a tool whose own history is two invented thresholds
caught only by controls. The same document states the principle it was breaking:
a control that does not execute is not a control.
tools/port/check-capture-controls rebuilds five of the six and asserts their
verdicts. The starved capture is gone and is reported MISSING rather than
omitted, and deliberately not synthesised from its published statistics -- a
control fitted to the answer it must give is not a control.
Two things the sweep had to learn to be honest about. check-capture emits TWO
verdicts and the doc's table compresses them; the voice control is PASS on
channels and UNJUDGED on starvation by design, so the sweep asserts the pair. And
a starved file short-circuits before the channel check, recorded as n/a rather
than FAIL -- the check did not run and the check failed are different facts.
My first 'real music bed' control was -ac 6 from a stereo source and FAILED
correctly: an upmix leaves channels silent and byte-identical, which is what the
provenance check exists to catch. The control was wrong, not the tool. Rebuilt
from six non-overlapping spans of real audio. A second attempt used aloop=-1 and
hung ffmpeg indefinitely.

Audits the open format spec against the validator by breaking each documented
requirement. Four of five caught. The fifth is the doc's error: FORMAT.md said
check refuses any peak >= 0 dBFS, where the implementation is kind-dependent --
a bgm is a sum we produced and is refused at full scale, an se/voice is a disc
wave whose lossy decode overshoots and is allowed to +1.0.
The doc was wrong about our own export: confirm ships at +0.18 and the ADV voice
at +0.31. A consumer implementing a validator from FORMAT.md would have rejected
a valid tree -- the file that exists so someone can check our work without
trusting us. Corrected, with the +1.0 marked as a judgement.
Also closes the last unread authored value: audio.json's was carried as
stems_why only, so serde ignored the value. Now deserialised and asserted in the
exporter (only sum is implemented); the assertion is proved to fire.
Files, not fixes: a failed export leaves a tree with no manifest, and every tool
then says 'is that an export tree?' -- which nearly made me conclude the
validator was checking nothing.

Applying the prior from six prior findings to authored/ itself: five keys had no
reader. dwell, ramp, left_right, input_during_transition, stems.
dwell is the one that mattered. Its own text says a measured hold goes there and
a number placed there did nothing -- and two iterations ago I asked the Decoder
for measurements destined for that slot. Wired now, and it stays EMPTY: the
splash dwells are declared on the disc and measured to agree.
I wired it to the wrong branch first and it did nothing, silently -- holding
longer after settle is absorbed because the screen still leaves at exit_time +
black_hold. A dwell must delay the departure. Caught only by testing the control:
+120 units moves the transition 4.46 -> 6.43 s.
ramp, left_right and input_during_transition describe hardcoded behaviour and are
written like switches. Rather than invent the missing implementations, they are
now asserted against the value the port was built for, naming the file -- which
is the distinction left_right's own why claims to make and was not making. The
validator is called, not merely defined.

MODDING.md calls modding a constraint on the exporter TODAY and nothing verified
it -- the same shape as the black hold, skipped[], stop_bed and --focus. All five
rules pass, so check-modding is a guard rather than a fix, and it is proved able
to fail: a stripped .cmd header, a bogus.bmp, and one orphaned PNG each exit 1.
It found one thing: the .cmd encode-cache sidecars sat in the modder-facing tree
with nothing saying what they were. They now carry a header. The header is
excluded from the cache key so rewording it does not re-encode four minutes of
video, and the sidecar is refreshed whenever its text differs rather than only on
re-encode -- otherwise a header change could never reach an existing export.
Also partly answers my own question to the Decoder: there is no general
capture-path floor, because the port matches live-title-press-a at 0.00093%
full-frame and 0.000% across the band. The 0.301% is specific to that pair.

live-attract-title-press-a-band.png is 1279x120 and the harness could not compare
a band. Placed by sliding: y=520, a 25x drop over five pixels, and it fits at
t=236-238, the plate's own window.
Its 0.354% is not the port's error. The port reproduces the same band of
live-title-press-a EXACTLY (0.000%), and the two captures differ from each other
by 0.301% -- two thin strips, 248x5 and 206x1, the shape of a sub-pixel edge
difference. The row's job is to stay near the oracle-to-oracle gap, not reach
zero, and it says so.
I had begun writing that the attract-returned title differs from the boot title.
It is two hairlines. The connected-component breakdown stopped it.

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.

live-title-press-a.png was unused in the corpus. Posed at t=237 -- inside the
plate's 8-unit window -- the port matches it at 0.00093%, against 0.0124% for
the no-plate capture at leaf phase ~400. Two captures, two different phases,
both under 0.013%: a systematic sweep-geometry error would leave a floor in
both, so last iteration's caveat is closed.
Sweeping the whole screen's instant against capture 1 gives at best 0.148% at
t=230 -- 10x worse than the leaf-only fit. So that capture is the screen SETTLED
with the sweeps still looping, which is the first independent evidence for the
authored loop_leaf decision.
Fixes the cause of a flat 1% floor: --screen=X --overlay=Y pushed the raw
elapsed clock into the overlay (9 units at capture), so press_start drew nothing
-- the flag whose purpose is 'put the plate on the title'. A static overlay now
poses at its own arrival; the --boot shared clock is untouched.
Adds title_plate to verify-capture at 0.00%, the most sensitive row in it. Its
instant is FITTED and labelled as such.
Also records that I nearly committed a wrong cause for the overlay bug: I wrote
that nothing drives the overlay's clock outside a sequence. It is driven, every
frame, from view.time_units.

The Decoder's refined sweep fit had never been testable: verify-capture passed
it as a whole-screen --time that pose_at discarded, and asking for it honestly
poses past the title's group end. --leaf-time separates the leaf's clock from
the screen's.
Controls: the renderer is deterministic (3 runs bit-identical) and the sweeps
move 0.40% of the frame between phases, so the comparison can see them.
Sweeping the full 600-unit span gives a sharp basin at 390-415 units (0.0124%)
against 0.2532% at t=357.7 -- 20x. So the title's 0.21% residual is the sweep
phase, not structure: at the fitted phase it matches the capture as well as the
splashes do.
NOT adopted: the port loops the leaf freely and re-posing the harness to the
fitted value would be tuning until they match. Filed instead, with the question
of whether 357.7 and this are even the same quantity.
Also verified last iteration's settle-window change was surgical: only
press_start and its twin moved, 14 screens unchanged including title's
Decoder-confirmed [160,236]. Settle-window ties exist on 4 screens but all sit
under the 30-unit bar, so the arbitrary tie-break never reaches the runtime.

1. --time= was silently ignored on any screen with a settle window >= 30 units:
pose_at overwrote the requested instant with settle_instant. ScreenView.frozen
now marks an explicit instant and skips both clamps.
2. press_start's settle window was [0,214] -- the dead stretch BEFORE the plate
exists -- so its settle instant was t=107, where the element is alpha 0. The
exporter now rejects intervals in which nothing is visible. title keeps
[160,236], the interval the Decoder's draw stream confirmed.
3. My authored looping_focus_records entry for press_start/ptbtn00 drew a dim
focus record INSTEAD of the plate's own sprite: max 0 vs max 252.5. Deleted --
an authored guess that overrides a decode with a worse answer is removed.
4. verify-capture passed --time=5.9617 for the title and it was never applied.
Every title figure it has printed, including the 0.26% quoted to the Decoder,
was measured at the settle instant under a note claiming t=357.7. Both rows now
pose by omission and the note matches. title is 0.21% honestly; splashes
unchanged at 0.01%.
The boot's end artifact now contains the plate (region mean 95.7 vs 33.6).
Corrects last iteration's BLOCKED row, which had the entry's effect backwards.

1. --capture with --script photographed before the first press (t=0.133 s, 10 of
16 elements transparent). Two runs differing by two presses came out
bit-identical and I read it as 'runtime focus never changes'. Deferred to the
end of the script; verified max 235 and t=82 units.
2. --boot --capture= wrote NO FILE: _finish_boot() is reachable only from the
overlay-quit branch, but line 412 quit first because _overlay_spec is cleared
when the overlay is raised. Pre-existing, confirmed by stashing. Fixed by also
requiring _overlay_quit_at < 0.0.
3. The artifact that now exists shows the boot's end frame is bit-identical to
the title alone -- no plate. ptbtn00 is opaque for 8 units (236-244) and the
boot captures at 246.54, because it waits for build 4 to finish fading at
t=261. Both halves of that are sound and they are incompatible. NOT changed;
filed, since what settles it is what the game does after t=244.
Defect 3 was invisible while defect 2 existed: a capture flag that writes nothing
cannot show a missing element.
Also records that runtime focus is FINE -- my contrary reading came from 410
files whose names did not match the flag I passed.

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.

MenuAudio.stop_bed() exists and is called from nowhere, so the bed started on
the main menu runs through S00A and loops on past it, putting two unrelated
music tracks on the bus at once. Established from the source and authored data,
not from measurement.
NOT silenced: MISSION says leave an unmeasured detail plainly wrong rather than
plausibly invented, and music over a cutscene is caught by any listener in a
second where ducking would sound right and be a guess. _play_video announces it
instead, and stop_bed is kept as the one line to change.
Also records that the envelope correlator is unreliable for music under music --
0.15-0.42 for every candidate, peaks moving with window and template. I was
drafting '46 s of unexplained audio' when the cause was the authored
loop: restart. A margin needs a control at the SAME SNR.

skipped[] has been tracked and read by nobody since P1, under a comment saying a
silently missing element looks like art. _note_structural prints from inside
ScreenView rather than returning a value for a caller -- routing it through a
caller is exactly what did not happen. Structural skips only; transparent-at-
rest is ordinary animation. Zero found today: a guard, not a fix.
The first version of that scan was a FALSE PASS: screen_view.gd did not parse
(a line inserted at three tabs inside a four-tab block -- the substring assert
matched a shallower indent), so grep counted zero from a dead script. The scan
now counts the summary line as a positive control.
Refutes 'the first-declared element paints first', which would have made the
forced-backdrop rule redundant since all six forced elements are index 0. False
on 8 of 16 screens -- decisively on main_menu, where index 0 is pteff00, painted
LAST, and pteff00 is a measured control.

NEW GAME opens S00A, plays 93.33 s against the manifest's 93.9, returns to
title. Nine film frames distinct and non-black.
Nearly filed 'the movie's audio never reaches the bus' from r=-0.0068 at the
movie's known start, with the correlator passing its own control at r=1.0000.
False: re-run bed-free on the boot path, movie audio r=0.418 and voice r=0.886
at the same start. The menu bed masked the quieter movie below detection.
The lesson is the control: I validated the instrument on clean data and ran it
on masked data. A negative needs a positive control under the SAME masking.
Third unvalidated negative in this corpus to nearly become a finding.
Also confirms the Decoder's unresolvable-element hazard does not reach
GP_TITLE: 115 .t32, 45 .rat, 18 .prm, no .tbm, every non-primitive resolvable.

The Decoder found forced_backdrop judged coverage from declared size alone.
pbafc.prm declares 844x600 at alpha ff and draws ~17x18 px at 2%x3% scale --
a rule reading declared size would call it screen-covering.
scale_at interpolates on the same ramp as the fade, and coverage is folded into
the opaque-instant test: an instant counts only where the element is BOTH alpha
255 and covering. The previous code tested the two halves at different times.
The size prefilter deliberately no longer rejects, since an element scaled above
100 could cover from a smaller declared size.
No verdict moves: 6 forced before and after, 16 screens validate, oracle figures
identical to the digit. Nothing in GP_TITLE has a non-100 scale on any keyframe.
It is in because the data that would break it exists, not because it failed.

verify-menu-audio records the Master bus over the P5 walk under the Dummy
driver. A dead press is bit-identical to the bed alone; all three cues match
their exported wave in the recording with margin over a bed-only control; the
cue order matches the script order, which the correlator was never told.
The first version of this tool counted envelope bursts above a multiple of the
bed and gave 4 cues on one run and 0 on the next from the same script. Replaced
with template matching, which has no tuned constant. Cue LENGTH is deliberately
not asserted -- the bed masks the tail and I nearly filed that as a defect.
Also acts on the Decoder's .tbm self-refutation. No port verdict is affected --
all six forced elements are .prm solid black, and GP_TITLE has no full-screen
.tbm at all -- but the guard was sprite.is_none(), a symptom test of the same
shape as the one they say fixed their symptom not their cause. Now role ==
primitive. Six verdicts identical, 16 screens validate.

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.

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.

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.

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.

The Decoder resolved it: palogo_eff0.prm is on BOTH splash pairs, publisher
running to t=255 (256 instants) and developer to t=210 (211). My own census
table had both numbers side by side and said the offset was not constant; I
filed a disagreement anyway by comparing one of my numbers to one of theirs.
Span convention confirmed as implemented. Records their counterfactual: the
hold decides 55% of verdicts disc-wide, and palogo_eff0's measured order rules
out the reading I nearly shipped.
Boot gate re-run after the reorder and still holds.

Tries to refute the rule by SUFFICIENCY rather than correctness: a strict
'all others visible' quantifier fails quietly, so the question is whether any
full-screen opaque backdrop misses the bar and keeps hiding its screen.
None does. Everything that fires is at 100% of others; everything that does not
is at 13-47%, and pteff02 never reaches alpha 255 at all. No borderline case.
Reproduces the Decoder's second control exactly (pteff00 forced below 3 of 23)
and shows their palogo_eff0 span gap is not a constant offset -- 211 is the
number our developer_logos row does reproduce.
Also retires the 'loading screen fade quad rests OPAQUE BLACK' row: resolved by
the rule, and it recorded rest.t as 38 where it is 0.

build_12 and build_15 rendered mean 0 at every instant of a PLAYING timeline,
and verify-screen scored both OK -- two renderers sharing implied_layer_key,
comparing nothing against nothing.
Implements the constraint as a post-pass over ui_layout::derived_paint_order,
with both of the Decoder's limits copied verbatim: layerless elements only (a
sprite's element alpha says nothing about its texture's coverage) and NOT a
name heuristic (palogo_eff0 is named like an overlay and paints first).
Both controls reproduce: palogo_eff0 forced first, pteff00 still last on all
four title screens at exactly 2 opaque instants. Splashes unmoved against the
oracle at 0.01%.

build_12 and build_15 have rendered blank since P3 and I had filed it as a rest()
casualty. It is not, and the corrected keyframe association makes it provable.
pgloading_eff00, a 1280x720 black quad, is opaque alpha 255 from t=0 to t=38 and
clears at t=48. Every other element on the screen peaks between t=8 and t=32 and
is gone by t=32-40. So the quad covers the entire span in which any content is
up, and clears only after everything else has faded. Rendered with the timeline
PLAYING at t = 20, 30, 36, 40, 42, 44, 46 and 50 units, the frame is mean 0 at
every one.
That is not a bad choice of pose. Under the port's current layer rule there is no
instant at which this screen shows anything, and a loading screen that is black
for its whole life is not what the game does -- a proof by contradiction rather
than a preference.
THE RULE UNDER SUSPICION IS MINE AND IT IS NARROW. pgloading_eff00 carries
layer_source "none" and the exporter sorts a layerless element LAST, on top.
Every other full-frame primitive in the export has a layer key (main_menu, extras
and title all give pteff00 0x00008030), so this only ever bites here -- which is
why it survived eight milestones behind two screens nobody draws.
Where a layerless element sorts is a DECODE and I have not answered it. If the
game sorts it first, behind everything, the screen renders and the quad becomes a
backdrop, which is consistent with the contradiction but not established. Asked
rather than flipped.
It does settle that verify-screen's BLANK verdict on those rows was right:
sylpheed-cli agrees with the port there precisely because it shares the
assumption under suspicion.
Also recorded: the Decoder has withdrawn "the game never draws eff3" -- it draws
all five -- and the mechanism is the one my developer-splash refutation caught a
layer down. A draw batches several quads and the log dumps only the first 8
vertices, so min/max merges them; eff3 lies entirely inside eff4 so the union is
exactly eff4's extent. My 525x259 was gamearts_eff merged with seta_eff the same
way. Nothing in the port changes: eff3 was never dropped and the splash still
draws three sprites.

extras sits at 0.19% differing against main_menu's 0.06%, on two screens of the
same family. The signed difference explains it: both are uniformly +9 to +12
brighter in the dark outer columns, in nearly identical patterns (+12.13/+12.29
against +11.63/+11.03 at x=0; +10.60/+9.05 against +10.24/+8.84 at x=960). That
is the transfer curve -- gamma > 1 in the darks -- with no dipole, no
displacement and no missing element.
So the 0.06/0.19 gap is not a difference in fidelity. The thresholded count only
sees pixels differing by more than 64 levels, which are text and sprite EDGES,
and the two screens have different amounts of high-contrast edge. The level
disagreement, which is what a tone term produces, is the same on both. I had
taken the ratio of two counts as meaningful -- the bounding-box lesson in a
different costume.
A DIAGNOSTIC TRAP OF MY OWN: the first pass reported 10 of 18 elements
"transparent at rest" on extras -- the buttons, the title, the frames -- and
looked exactly like a missing-element bug. `--screen=NAME` without `--time`
renders at t=0, and pose_at clamps t to minf(t, settle_units), so t=0 stays t=0.
With --time=2.0 it draws 18 of 18. The tool was right and my invocation was
wrong, and it reported a WORSE problem than existed, which wastes an iteration
rather than hiding one.
REFUTATION ATTEMPT, SURVIVED: the Decoder's 239.8 units for palogo_sqex's alpha
>= 1 span, which is the denominator of the units-per-frame conversion behind the
9-unit black hold I just authored. Computed independently from my export under
the linear ramp the port already uses: alpha first reaches 1 at t=15.0588 and
last exceeds it at t=254.8750, giving 239.816 units. Agrees to four significant
figures, from different sides of the same record -- which is what makes that
constant safe to hold.

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.

Claude-Session: https://claude.ai/code/session_01N7FiFFFwbvG2uxdcEh8HyF
TWO RESULTS, both correcting things I had written.
THE NARROW SETTLE WINDOWS ARE NOT A GAP. Adopting the settle instant left
main_menu and extras on per-element rest() -- windows of 12 units, below the
30-unit bar -- and I recorded that as something left behind. rest() is malformed
only for a TRANSIENT, and the transients are precisely on the screens whose
windows are wide: title (76) has ten, publisher_logo (190) and developer_logos
(145) have one and three, and main_menu and extras have NONE. The discriminator
is returning to dark far before the screen's own end -- ptlogo_back2eff1 is dark
again at t=58 while the title runs to t=269 -- as against the ordinary
fade-in-hold-fade-out every menu element has, where rest at 255 IS the settled
pose. Not claimed as a rule: two screens having narrow windows and no transients
could be coincidence, and n=2 is where I have gone wrong before.
REFUTED, MINE: "the menu residual is localised on the ptloop sweeps", which I
have written twice. It came from reading the BOUNDING BOX, which sat at (441,230)
-- the sweep position. Sweeping the leaf's phase against the live-menu capture:
0.063% at t=60, 0.183% mid-screen at t=350, 0.061% parked at t>=600. With them
parked the box is 834x358 at (445,167) -- the button column, where the focus
signature lives. On extras the same test moves the box (398x295 at the sweep
position, then 736x525 spread) while the magnitude barely changes, 0.192% against
0.200%.
So the box moves with the sweeps and the residual does not. A bounding box over
scattered pixels tells you where the outermost differing pixels are, not where
the difference is -- and I had been quoting it as if it localised a cause.
verify-capture prints that box, so this is a caution about reading my own tool.
And a first piece of evidence on whether the sweeps loop: the disc gives one pass
ending parked off-screen, ORACLE-CAPTURES says they "move continuously" which I
had read as implying a loop, and the idle menu capture matches best with them
OFF-SCREEN. One capture and a weak instrument for an absence, but it is the first
evidence either way and it points against looping.

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.

Claude-Session: https://claude.ai/code/session_01N7FiFFFwbvG2uxdcEh8HyF
The Decoder caught the title's build-in on the console and found ptlogo_back2eff3
never drawn -- not a miss, but phase: a flash's peak is 2 keyframe units, 0.85 of
a presented frame at that pacing, so the console shows a SUBSET on any given
play. The warning was that drawing all five would read heavier than the real
thing.
Checked rather than reasoned about. Sweeping the build-in with --no-hold, the
port draws them sequentially -- eff1 at t54-56, eff2 at 58-60, eff3 at 60-62,
eff4 at 62-64, eff5 at 64-68 -- never more than two at once, and those only where
their declared windows abut. That is the stagger the disc declares. The pile-up
was the rest() bug and it is fixed.
SO THE DIFFERENCE FROM THE CONSOLE IS PRESENTATION RATE, NOT CONTENT. At 60 fps
each 2-unit flash gets ~2 frames; at the console's pacing it gets 0.85, so some
are skipped. A frame-by-frame comparison of the build-in against a console
capture will show flashes the console missed -- a fact to know rather than a bug
to fix. The settled comparison verify-capture makes is unaffected: at t=198 none
of the five is drawn.
Also recorded: my top-level restriction on the settle window was verified by them
rather than merely accepted ([160,236] width 76 against [269,540] width 271 with
the leaves in, which is an instant after every top-level element has exited); the
120-unit loop is confirmed from the guest's own vertex colour alpha, observed
range 0..80 against a decoded peak of 80, with the decoded ramp fitting at RMS
13.16 against 38.18 reversed; and a trap for any future draw-stream tooling here
-- a 2D draw's identity is its vertex geometry, not its bound texture, because
these sprites sample large shared pages.

The Decoder's finding, applied. `rest()` returns each element's last hold
keyframe chosen independently of every other element: right for anything that
ends the screen settled, exactly wrong for a transient. The title's
ptlogo_back2eff1 is a two-frame flash (0 until t52, 255 at t54-56, 0 by t58), so
its last hold IS the flash peak and rest() left it burning -- five of them, drawn
at once.
The settled instant is the longest interval containing no keyframe time, over a
bundle's TOP-LEVEL elements. Reproduced here before adopting: title [160, 236],
midpoint 198, the Decoder's number to the unit. The top-level restriction is what
makes it match -- including the ptloop leaves gives [269, 540].
AGAINST THE ORACLE:
title 20.92 RMSE 1.81% -> 14.61 RMSE 0.26%
publisher_logo 9.05 0.75% -> 2.17 0.01%
developer_logos 8.86 0.33% -> 3.05 0.01%
main_menu 0.08% -> 0.08% window too narrow
extras 0.19% -> 0.19% window too narrow
Seven times fewer differing pixels on the title, seventy-five times fewer on the
publisher splash, whose differing region is now a 13x18 box. The largest
correctness gain this port has had, and none of it is mine -- it is a decode
computed from the keyframe table with no reference to any capture.
APPLIED ONLY WHERE THE WINDOW IS WIDE, and the bar is not invented. This export's
widths split with nothing in between: 214, 190, 145, 76, then 12, 12, 8, 4. The
bar is 30 units -- the Decoder's disc-wide census puts the knee there (30% of
bundles >= 30, 42% under 10, the latter mostly loop* fragments meant to be in
motion) and this export's screens sit 4x either side with nothing between 12 and
46. Two independent populations agreeing on where to cut.
Checked unbroken: boot pacing unmoved, scripted walk runs end to end with focus
restored.
Also recorded: my "34 focus-record elements, only 2 varying" is right for
GP_TITLE and reads as a fact about the format -- disc-wide it is 210 varying, 202
with rest() at the peak, concentrated in the paks a wider port reaches next. And
their sharper framing, which I have adopted: a pulsing element has no resting
pose at all, so rest() is MALFORMED rather than mis-answered on one.

The old figure was 24 overlapping tied pairs, and it was a rest() count: 10 of
the title's 11 tied pairs are between the five transient flashes, which are
transparent on a settled screen. Measured at settle, the cost is ZERO on all five
screens this port ships, and the only non-zero anywhere in GP_TITLE is 1 px at
delta 1 on the Japanese title, which is out of scope. Sweeping every keyframe
time and midpoint, the live-pair count is flat across the settle window, so it is
not a knife-edge.
Recorded with the Decoder's own caveat rather than smoothed: four loading bundles
report zero with no live control, so those are a weaker zero than the other six.
And why ties order as they do is still unknown -- it now costs one pixel.

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.

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.

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.
