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

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
replacement quotes the refuted sentences in order to name them.

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

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.

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.

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.

#4 answered: ADV.wmv carries ONE audio stream and it is WMA Pro 5.1, not XMA, so
the movie's own track is the bed and the three streams are additional. Solving
capture = 0.600 x movie + residual gives three residual signals at three
positions, with LFE reproducing to -115.73 dBFS -- where nothing is added the
decoders agree exactly, so the rest is added content.
presentation: all keeps every equal-length non-silent survivor -- ADV 2 of 3,
S00A 1 of 3 -- and the warning now keys on kept < present rather than on more
than one existing.
A unity sum was tried first and check refused it at +2.62 dBFS. The BGM stems
precedent did not transfer: those are stems of one signal, these are positions in
a field whose downmix weights sum to one whatever the assignment. Dividing by the
count preserves the total and claims nothing about placement; ADV lands at -3.1.
That is the OPPOSITE of the two divisor bugs already in this file, where a silent
input sat in the divisor. Divide-by-N is not right or wrong in itself.
Also carries their census correction: the ALSA permutation does not apply, the
map is the identity, and the '82% silent' channel was LFE.

With their predicate the port's render is comparable to their capture for the
first time: pulse minimum 805 against their 714, peak 1420 against 1520, both far
above the 154 floor. So 'never goes off' holds in the port's own render.
My pulse is 24% shallower and I am NOT tuning it -- their own limit says the
counter is thresholded pixels, so a depth measured this way is a fact about the
threshold as much as the glow. The port draws the declared ramp.
#4: 148 s of the game's output, five of six channels distinct, no channel a copy,
largest pairwise correlation 0.70 between FL and FR. So presentation: loudest --
keeping one stream -- is refuted by what the game PLAYS, not merely suspected.
Stays unfixed on their instruction: the stream-to-channel mapping is not run, and
swapping one authored guess for another is worse than a guess that is labelled.
Also records that '6 channels' is Xenia's hardcoded default, not evidence of 5.1.

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.

TWO FINDINGS, one mine and one handed to me, and the second retires a premise I
built on twice.
THE P1 BASELINE HAD ROWS THAT PROVED NOTHING. `build_12` and `build_15` render
pure black in BOTH renderers -- mean 0, max 0 -- so the difference is zero and
`verify-screen` scored them `max 0 over3 0 OK`, the strongest verdict it has.
Two of sixteen rows were comparing nothing against nothing. Worse than a missing
test, because a missing test is visible in the count.
Cause isolated by a control, not by reading: `build_00`/`build_01` are the same
loading screen minus three elements and render fine (mean 1.913, max 214.5). The
dressed variants add `pgloading_eff00`, a 1280x720 primitive resting OPAQUE BLACK
at t=38 inside its own opening black hold, with no layer key so paint order puts
it last.
The rule I was about to write -- "rest.t before the last timed keyframe is the
pathology" -- was killed by running the census first: 152 of 212 elements in this
export have rest.t earlier than their last timed keyframe. It is the norm. What
is actually unusual is the CONTENT, and its reach is one: `pgloading_eff00` is
the only element in the export whose resting pose is a fully opaque full-frame
quad. One instance is not a rule, so the renderer is unchanged and the HARNESS is
fixed: a blank pair now reports BLANK -- both renderers drew nothing; this row
proves nothing. `status` is untouched, so an unrelated DIFFERS still fails.
THE VOICE EXPORT IS KNOWN INCOMPLETE. The Decoder booted Canary with
--xma_param_probe and the game decodes ALL THREE streams CONCURRENTLY, in three
XMA contexts whose byte sizes match the disc payloads exactly. So "three
presentations of one take, pick one" is refuted by the running game and the
question I had been arguing -- WHICH presentation -- has no answer.
This one no census could have caught. Every measurement was right: the streams
are equal-duration, one is silence, one is 0.60x another with the residual 26.8
dB down. The frame around them was wrong, and the file says ChannelMask 0x0002 on
all three. It took the running game -- which is the mission's own sentence
arriving in practice.
BEHAVIOUR HELD DELIBERATELY. An equal-gain 1/n sum of channel pairs is not a
downmix either -- MISSION section 6 pins an explicit matrix for exactly that
reason -- and summing cost S00A 6.02 dB when one stream was silence. Swapping one
guess for another on a message is what produced this entry twice. What changed is
that the wrongness is now LOUD, because this failure sounds like success: one
stream is clean audible dialogue. A top-level manifest warning per movie, the
console line, and the authored entry all say `1 of 3 streams`.
"They are 5.1" is recorded as the Decoder's HYPOTHESIS with its own
counter-evidence attached, and nothing builds on it. What settles it is asked: a
recording of the game's own output over ADV through the null sink, which turns
channel roles into a fit against an oracle.
Refutation attempt, survived: the Decoder's loading-screen variant map. Entries
0/1 carry 7 elements and 12/15 carry those seven plus baseeff, eff00 and loop5 --
exact in count and identity, and it is what made build_00 a control.

I argued `highest_rate` had no case because ADV's higher-rate presentation is
dual-mono while its louder one is mono-in-stereo, so the extra bytes buy a
duplicated channel rather than fidelity. The Decoder tested that disc-wide over
the 28 three-stream cues: the stream-3/stream-2 size ratio runs min 0.0778,
median 1.2565, max 2.9163, sd 0.5057, with only 12 of 28 within 15% of 1.0, and
declared rates scatter with them. A 37x spread is not a duplicated channel.
The CHANNEL MEASUREMENT STANDS -- ADV chunk 1 is mono-in-stereo and chunk 2 is
dual-mono at -8.318574, this port's own decode, which the Decoder could not
re-run and did not dispute. What fails is the step from one asset to the format.
NOTHING IN THE EXPORT CHANGES. `loudest` is a per-asset content rule -- it reads
the peak of the streams in front of it -- so a scattering structural ratio cannot
undermine it. What changes is the REASON, in four places: authored/audio.json's
presentation_why, the selector comment in audio.rs, BLOCKED.md's row, and
DECISIONS.md. The honest statement is narrower: `highest_rate` was never refuted,
it was never argued for, and neither is `loudest`. That is why the entry is
marked CHOSEN rather than measured, and why one capture deletes it.
Recorded on the pattern rather than just the instance: this is the third claim of
mine in two iterations that generalised a single-asset observation, after "the
chunks are two stems" and "everything the sequencer paces off rest.t is late".
All three were true of the thing I looked at. The failure is reaching for the
rule a measurement would imply if it held everywhere and writing that down in the
same breath as the measurement.
Also noted, not mine and not affecting export_voice: S12B's three streams are
byte-size identical, and BIRD_224 is three-stream while not being a movie cue.

THE TRANSCODE CACHE HAD NEVER HIT. `video::transcode` has carried one since P4 --
a `.cmd` sidecar with the command, the source size and the channel count -- and
`main.rs` clears the output tree wholesale immediately before the check, deleting
the sidecar and the file it stamps. Six exports in this session paid the full
Theora encode and produced five byte-identical files, roughly 48 minutes. Nothing
reported it, and nothing could: a cache is silent either way and the only symptom
is a wall clock that looks like the job being slow. The wipe now spares `video/`
and `prune_videos` deletes anything in it this run did not claim, so the
wholesale guarantee is kept rather than traded. A re-export is 20 s.
SETTLE TIMES, MEASURED, and they refute more of my row than they confirm. The
principle holds -- the title's rest.t is 251 units = 4.183 s where its art
finishes at ~2 s -- but "everything the sequencer paces off that landmark is
therefore late" does not. Measured the port the way the game was measured, by
VISIBLE SPAN rather than arrival-to-arrival:
publisher wordmark port 4.25 s game 4.297 / 4.604 / 4.370
developer logos port 3.50 s game 3.508 / 3.503 / 3.366
black hold port ~0.25 s game 0.2 - 0.3
title -> plate port 2.000 s (declared 120 units) game 2.247 s
Dead on. My earlier reading compared the port's transition timestamps against the
game's visible spans, which differ by the exit ramp plus the black hold -- the
whole of the discrepancy I was about to chase, and the same definitional trap
that cost this corpus 0.48 s on the plate delay. Nothing in the sequencer is
changed. `dwell_seconds` stays null, now for a measured reason rather than an
absent one: `timing.json` said "if a capture ever times the real boot, this is
where that number goes", and the answer is that nothing goes there.
Not authored, deliberately: an (A)->menu dwell, which measures 3.763 s and
contains a 1.53 s guest load stall on a cold cache; and the menu build-in and
(B)->title, which rest on one run where the port is already within ~0.1 s.
THE VOICE PRESENTATION MOVED TO authored/, because the recommendation behind it
was withdrawn as self-contradictory and the choice is now unambiguously mine.
`voice.presentation` = `loudest`, and the reason to switch is a measurement, not
a preference: ADV chunk 1 is MONO-IN-STEREO and chunk 2 is DUAL-MONO, so chunk
2's extra bytes encode a duplicate channel rather than fidelity. That explains
the byte-rate difference and removes the only argument for `highest_rate`. ADV's
dialogue now exports at +0.3 dBFS instead of -8.7, which is the SE bound's
documented decode overshoot on a wave mastered at full scale.

The three Static.slb cues and the menu bed now export to Ogg Vorbis and play.
`sylpheed_formats::media` does the assembly; nothing in port/ has heard of XMA.
Three things this milestone got wrong before it got right, all recorded in
docs/port/DECISIONS.md because the corrections are the useful part:
1. The cue offsets were a Rust `const` in the exporter. They are MEASURED, not
decoded -- a measured value compiled into the exporter is a measurement
wearing the costume of a decoded field, and nobody deletes it because nobody
can see it. They are authored/audio.json now.
2. I picked BGM_001 and wrote a careful `why` calling the choice arbitrary. The
menu's music is BGM_103, and it is in HANDOFF at 0fd8e69 -- the exact commit
BLOCKED.md says that row was reconciled against. Not stale: wrong when
written. I had summarised a negative without its reach, so "the TABLES cannot
say which BGM a screen plays" became "it is not on the disc". One word of
scope was the whole answer, and the export failed only because BGM_001
without its .slb extension hashes to nothing. That is luck, not design.
3. The comment above the BGM sum argued for unity gain "because halving is a mix
decision nobody made". It clipped at +1.8 dBFS. 1/n is the smallest constant
that provably cannot clip -- the same reasoning video.rs already carried for
its 5.1 downmix, in this repository, unread.
Unsettled and shipped as such: media::sound_bank_riffs returns THREE sub-waves
for BGM_103.slb where HANDOFF Q10's census says exactly two (the third is the
leading headerless region slb.rs emits for the voice path). The exporter sums all
three and writes a manifest warning, because which bytes belong together is the
decoders' question, not this exporter's -- and dropping one would destroy the
evidence, since a corrected export looks exactly like a correct one. Raised with
the Decoder; row in BLOCKED.md.
The gate is a null control, not a peak reading. A master-bus WAV that is
non-silent proves nothing -- the bed alone would look identical. So the same
scripted walk was run with <- in place of <v>, which fires no cue (Q5, measured),
and the difference is one 0.55 s burst at t=1.10 s and silence everywhere else.
The first attempt at that control returned bit-identical zero and I nearly filed
it as "cues never reach the bus": both runs ended at 1.115 s and the first press
lands at 1.17 s. A null result from an instrument that was not running is not a
null result.
Refutation attempt: HANDOFF Q8's three cue durations. They looked attackable --
0.133/0.172/0.169 s per packet, no shared rate -- but an XMA1 packet carries a
variable number of 512-sample frames, and the three come to 50.0/32.3/95.3
frames. Measured off the decoded Ogg: 0.533, 0.344, 1.016 s, every published
digit. SURVIVES, with its reach stated -- it confirms the assembly path and my
transcription, not the event bindings, which only an oracle can retake.
