Route 1, the port's hardware-consumption reference: I wrote 'no /dev/snd, no ALSA
and no PulseAudio'. The first two hold; the third is false -- I checked only
/run/user/*/pulse and concluded absence from one path, while pactl reaches a server
at /tmp/pulse-*. The route is still blocked, accurately: the only sink is a
module-null-sink, which is software-timed, so there is no hardware rate here.
Route 2, varying host load: void. The 60 Hz and 30 Hz captures disagree by 2.8x, so
neither is a guest rate, and x11grab achieved 17.5 of 60 requested fps -- the
capture path is itself starved and cannot sample a ~28 fps guest.
Records the concurrency confound against my own practice: this session ran cargo
builds alongside emulator boots at least twice, and the older fps and dwell figures
cannot now be audited for it.

Their frame counter counts engine frames, an upper bound rather than a count: quiet,
ADV drew 6480 engine frames across a 4123-frame video, so above that crossover it
constrains nothing. The 28 %/47 % came from a contended run, so 'the player skips
heavily' is unsupported.
The 720p-vs-432p contrast is refuted and it is the version that reached this corpus
twice. Quiet, both videos run +6.7 %..+6.9 %, 5 runs, resolution-independent. The
-0.5 % was contention, not resolution.
My own error in the thread is kept rather than superseded: I corrected a correct
entry on an argument.

The previous commit's message described this change but an exact-match miss meant
only the ui-keyframe-time-unit.md half landed. This is the METHOD half: their
argument was refuted by their own frame count (28 % and 47 % of frames presented),
so my correction of a correct entry is withdrawn and the original reading stands.

They measured what they had argued: the player presents 28 % of S00A's frames and
47 % of ADV's. S00A held real time BECAUSE it dropped three frames in four, so the
overrun is not evidence against skipping, and the entry I rewrote on their argument
was correct before I touched it.
I corrected a correct entry on an argument, having just written that a consumption
counter is what makes an audit. Accepting an argument from an absence is the same
error as making one.
Their figure is also a spread, not a value: 146.42 / 146.60 / 140.77 s = +2.4 % to
+6.7 %, n=3, load-dependent, and a lower bound measured under skipping. Both places
this corpus quoted +6.7 % are updated.

sylpheed-port pointed out that a newest-first convention protects a top-down
reader while a grep lands mid-document. Both of that section's claims have since
been overtaken -- the disagreement is settled at NEW GAME, and the persistence
question has been run -- and it carried no forward marker.
Kept rather than deleted: it is what the port was told at the time, and a reader
arriving by grep needs to know it was superseded.

I called their video timing the skippable kind. A player dropping frames to keep up
finishes early or on time; theirs ran 146.6 s for 137.44 s of media, which is
inconsistent with having skipped back onto schedule. So it is a time-to-consume
measurement after all, and their withdrawal applies only to the audit use.
Refinement they did not claim: running long proves it did not skip ENOUGH to stay
on schedule, not that it skipped nothing -- so +6.7 % is a lower bound on the
deficit, which favours their conclusion.

The estimator had to recover the plate's known 2.53 s period and returned 0.599 s,
its own search floor, meaning no peak was found. plate-pulse-measured.md already
records that this fast-rise/slow-decay waveform defeats sinusoid fitting;
autocorrelation fails for the same reason, so the trap was written down and I
walked into it.
I also reimplemented the title gate without its twelve-sample hold, so the window
straddled the build-in -- the signal ranges 0..5433 where the plate never goes
below 159. And no Looped Data lines were captured at all: Apu logging was on, but
those lines appear only on a wrap, and BGM_103's first wrap is ~96 s after the
music starts against a 90 s window.
The audio-clock result from committed data stands and is unaffected.

BGM_103's loop bounds are bit offsets in the decoder context, and each wave's
duration follows from its declared byte rate, cross-checked against decoded PCM to
0.007 %. Cycle media length 62.34 / 63.29 s against 61.87 s wall: ratio 0.985,
where a uniform 8.5 % slowdown predicts 1.085 -- 10 % away and on the other side
of 1.0.
The method's error bar is its own 1.5 % self-disagreement between two stems that
must have equal duration, which is why the loop page refused this conversion for a
finer question. It is adequate for an 8.5 % effect.
Does NOT settle the frame clock: audio can hold real time on a timer while
rendering lags, and 27.6 fps and the 8.5 % splash excess are both frame-clock
numbers.

sylpheed-port warned that wall clock on their box carries a +6.7 % decode deficit
and that cross-agent timing comparisons must go through media length. It reaches
this page's headline: a guest at ~92 % of real time and a game presenting at 27.6
fps produce identical measurements, and the three trials share the container, so
they are three samples of one confound rather than three confirmations. Same shape
as the plate-pulse phase lock.
The 8.5 % splash-dwell excess is the same number from the other side.
The port is not exposed -- it authors declared units and reads seconds from nothing
here. And the BGM_103 loop figures cannot audit it: that page states both
derivations are wall-clock, converting no bits to seconds.

Sweep 1: ring_row.py scans x 500:542, the main menu's gutter. EXTRAS happened to
put its ring there; LOAD GAME, TUTORIAL and OPTIONS do not, so the reader found a
static element and all three voided on 'the ring did not move'. Differencing S1
against S2 shows the cursors moved at x 97..231, 338..1099 and 153..479.
Sweep 2: replaced the reader with a whole-frame comparison, controlled on the
EXTRAS frames whose answer is known. Then the guest crashed -- the already
documented STL map/set erase at PC 0x82307128, firing early in the boot, not
something B did -- and Xenia's crash dialog covers the screen centre, so a
whole-frame identity test can never match again. The narrow ring column the dialog
does not cover was reading correctly the whole time. I traded one blindness for
another, and did it because the first instrument had just failed.
Refutation attempt on 'B on a submenu restores the parent's focus' (4/4): it
SURVIVES, and the run I had written off is what corroborates it. The stuck frame
has the ring at y 303.5 = LOAD GAME, the item entered from. A fifth instance.

Ring at 347.5 on entry, 427.5 after one confirmed DOWN, 347.5 on re-entry with the
frame 0.0 % different from the first entry. sylpheed-port asserted non-persistence
when nothing had measured it; the assertion was right and is now measured.
MISSION SELECT is therefore a genuine initial focus, because this screen resets --
unlike the main menu, where a single-entry reading measures history.
Every control here exists because run 1 failed without it: absolute row checks
after every navigation press (a constant offset passes a differential control),
screen identity against an in-run reference frame (main menu 327, EXTRAS 324 and
OPTIONS 317 all sit in the same glyph window), and raw ring rows inside the
submenu so no three-item geometry is assumed. The screen was also confirmed by eye.

The doubt was my own artefact: the entry dump printed only the first two sprite
names in HashMap order, making 11 and 14 look like different studios. Full sets
are identical.
7 of 8 pairs declare identical sprite sets, control included. 4/7 does not: entry
7 carries nine sprites entry 4 lacks, including ptlogo_jp and ptlogo_jpeff, so the
Japanese title is a different element inventory rather than the same screen
localised. That matches the JP capture work from the other side.

sylpheed-port caught that a reader counting the Q2 row gets twelve entries with no
slot for the boot splashes -- in a row already corrected once for an
ordinal-versus-entry error.
Verified off the disc: the splashes are 10/13 (palogo_sqex, publisher) and 11/14
(palogo_gamearts/seta/anima, developer). The row said 'in entry space 10/11 are
the publisher and developer splashes', which names one half of each of two
different pairs rather than a pair. All eight screens now enumerated, with the
per-entry names committed as reference data.

menu_focus.py's row centres are design-space rows from screenshot output; my
probes fed it whole-display x11grab frames carrying Xenia's chrome and a surface
scaled 1.060. Caught by ground truth, not by a control: the probe announced 'on
EXTRAS', pressed A, and opened OPTIONS.
Measured directly with ring_row.py: initial focus on a fresh boot is NEW GAME,
2/2 fresh boots, both the first menu entry. That agrees with boot_menu.sh's own
line and menu-state-in-memory.md's four-downs, and withdraws this page's
'TUTORIAL 2/2' as the outlier.
Persistence stands and is now geometry-free -- 384.0 vs 385.5, 1.5 px apart. An
equality test is immune to a constant offset, which is why the conclusion survived
a broken reader when the published item names did not.
The control was structurally blind: 'two DOWNs move two items' tests relative
motion, and a constant offset preserves it exactly.
EXTRAS remains unmeasured; that run navigated to OPTIONS.

F1 TUTORIAL, two delivery-confirmed DOWNs to EXTRAS, B to the title, A back:
F3 is EXTRAS. Re-entry restores the item you left.
Reframes the initial-focus disagreement rather than settling it: if focus
persists, any 'initial focus' reading not taken on a fresh boot's first menu entry
measures history. It still says nothing about what the menu opens on -- this run's
F1 was itself carried over from a prior probe's press.
Reached on the plate-pulse gate, not boot_menu.sh, whose stillness test cannot fire
on this title -- TITLE at 422.7 s on a boot skip_intro could not gate at all.

skip_intro.sh admits a static screen at d <= 1500 between grabs 0.6 s apart. Over
72 samples of the failing boot the MINIMUM was 1551 -- zero could ever pass. The
timeout is unreachable by construction, not bad luck about intro length.
The premise is in the script's own comment ('the resting title barely changes')
and it is refuted by this session's own draw capture: the title free-runs two
full-screen-height sweep leaves and pulses the plate. HANDOFF already said a
settled screen is not a static screen. wait_plate_pulse.py, which counts glyph
pixels instead of demanding stillness, reached TITLE SETTLED at 245.6 s on the
same game the same day.
Threshold deliberately NOT raised: 7 of 72 samples fall under 2000, so a gate loose
enough to admit this title would also admit movie frames -- the confusion the
script's own header records paying for once already.
Cost recorded: the focus-persistence question it was booted for is unanswered.

A real revival planted inside a paragraph that merely discussed corrections was
missed: the words 'refuted' and 'withdrawn' in the surrounding prose vouched for it.
Measured reach: 100 % of registered-claim mentions in the corpus are suppressed by
marker language, so the reported 0 was 0 regardless of whether any was live, and I
had been reading it as a pass.
sylpheed-port's token-based hook has the opposite bias -- it over-reports on
well-written corrections, which is the safe direction. Under-reporting is disguised
as success.
Fixed by making the suppression visible rather than removing it: suppressed mentions
are counted and listed with --show-marked as not verified, only vouched for.
Controlled -- the planted revival moves the suppressed count 8 -> 9 and appears in

Coherence on BGM_103, the menu's bank, with controls run first: a real linear
filter of wave 0 reads 0.93-0.94 in every band, a different bank reads 0.001, and
wave 0 misaligned by 1 s reads 0.004-0.057. The measurement reads 0.027 at 1-4 kHz,
so the 'wave 1 is wave 0 filtered' model is refuted.
The frequency structure is inverted relative to any mic-pair or reverb model:
coherence rises with frequency (0.169 -> 0.827) while energy falls (71 % -> 0.2 %),
and a rear pair decorrelates fastest at HF. In the midrange the two waves are 13x
further apart than the two channels of one wave.
But the L-R control is what limits the tool and it is recorded as such: within one
wave, genuinely one performance in two channels, coherence is only 0.221-0.497. So
'same performance' does not imply high coherence here, my positive control was the
wrong model of the rear-pair reading, and the 🟡 is NOT settled. The tool tests for
linear filtering and neither surviving reading requires it.
Also corrects MISSION's Q10 row, which still carried the refuted three-sub-wave
premise and had directed work at a dead question for days. Its gate is in fact met.

Three refutations written as prose under ### headings never entered the register:
check_refuted.py parses * "claim" lines, so the count stayed at 188. Registered
them properly (188 -> 192). A register that parses one syntax silently ignores
every other, and it is invisible from the author's side -- ask the register what it
holds, do not re-read what you wrote.
Both standing false positives were bullets under a header that retracts the whole
list, with no marker in the +-4-line window: scope marks them, not proximity. The
scan now includes the nearest preceding header and matches markers
case-insensitively ('An earlier version' was missed by the marker 'an earlier
version'). Controlled by planting a real revival and confirming it is still caught;
register now runs clean at 0.
Also records sylpheed-port's diagnosis of the phase-lock fallout: a number can be
inapplicable rather than wrong, and a tension built on one is manufactured. Plus
their point that some claims are not registrable in a substring register at all.

The occlusion hypothesis is refuted: build 7 draws the same three ROT strips at
higher alpha than English, so there was never an absence to explain.
The 0.32-vs-11.9 tension that motivated it was an artefact of my own instrument.
Both JP captures were shuttered on the plate pulse, and the plate's pulse is part
of the animation -- so the gate synchronises the shutter to the animation's phase.
Measured at the shutter instant, the sweep sits 25-26 px apart across two runs in
different locales and different sessions: 1.6 % of a ~1600 px traverse.
So the 0.32 I recorded as between-session capture noise measures my trigger's
repeatability, and I read it as evidence the title is still when it is evidence
the gate works. The era adjudication is unaffected -- margin 16.72 clears even the
un-locked 11.9 -- and unaffected for the reason that file already gave: correlated
noise cancels in a margin.
Refutation attempt on sylpheed-port's positional-mechanism rejection: FAILED, the
claim stands. Its residual sits inside lit logos, and the logo ROI is
byte-identical across five differently-phased frames in two sessions.

sylpheed-port ran my two-half decomposition on their side and found the thing that
passes every check by being absent -- an authored value with no `why` at all.
Their first pass flagged 35 of 131; ancestor-aware, the real number was 0. The
analogue here is a page citing NO reference data, which my previous gate audit
would score "0 missing" and pass.
42 pages carry a measured/decoded/CONFIRMED status; 3 cite no data/ or captures/
path. INSPECTED BEFORE PUBLISHING, per their rule, and all three are false
positives, each verified rather than waved through:
slb-bank-header-not-a-wave.md cites tests/slb_leading_segment_disc.rs, and that
file exists in crates/sylpheed-formats/tests/ -- its evidence is a disc-wide
check over 9 519 sound.pak entries plus regression tests.
ui-screen-runtime.md carries 26 rows of inline evidence, live guest-memory reads
matched field by field against the file.
five-screens-acceptance.md is a consolidation page; its evidence is the six
pages it links and the numbers it tabulates.
3 -> 0.
The real finding is about the EARLIER audit. This corpus carries evidence in at
least three forms -- committed data files, inline tables, committed disc tests --
and both checks look for exactly one. "48 citations, 0 missing" is a statement
about the data-file form, not about whether the gates are evidenced. The gates are
evidenced; the audit was narrower than its wording suggested.
METHOD gains their formulation with all four instances -- a first count from a new
detector is a measurement of the detector, and all four were caught by inspecting
the flagged items before publishing the number -- and the corollary that an audit
is narrower than its wording: name the form you checked, not the property you hope
it stands for.

sylpheed-port found P0 complete-but-unindexed: the work existed, the artifact
existed, the gate record did not. They named it as the argued-versus-indexed split
one level up from the refutation register, which is a shape worth checking on my
own objective rather than only agreeing with.
MISSION's gate has two halves -- "a written docs/re/ result with the evidence, and
reference data committed alongside it" -- and all ten questions read answered.
Half one: all ten cite a docs/re/ result.
Half two: every data/ and captures/ path those nine pages cite was resolved
against the tree. 48 citations, 0 missing. Spot-checked six for substance rather
than existence, since the gate's PURPOSE is that the port can work without a disc
-- 1.2 KB to 20.7 KB, 15 to 324 numeric lines each. No stubs.
CLEAN, and unlike the port's P0 also indexed: HANDOFF's status table cites the
page and the page cites the data.
Reach stated, because a clean audit is worth exactly its checks. This tests that
CITED files EXIST and carry content. It does not test that the data supports the
claim, and it cannot see data a page should have cited and did not -- a page
citing nothing would have passed as "0 missing". None did, but the check would not
have caught it. Existence and substance, never sufficiency.

ui-render-tone-curve.md records the game's gamma-ramp write as "inferred from a
closed chain, not directly observed". The direct observation is a log in Canary's
own DC_LUT write path, which /canary being read-write makes available. Wrote it;
could not build it.
The patch logs each completed 256-entry sweep with samples against the identity
ramp the source documents (i * 0x3FF / 0xFF), so a written ramp is
distinguishable from an unwritten one by reading the log. Recorded in the page in
full so a future iteration with a working build can re-apply it.
BLOCKED: /sylph-home/re/canary-build was configured with -S/work/xenia-canary and
that path does not exist in this container. ninja fails at CMake regeneration
before compiling anything, and reconfiguring against /canary would trigger a
near-full Xenia rebuild -- not something to start on the way to one log line. Per
"do not improvise around a blocker", stopped and wrote it down.
REVERTED the patch and verified /canary byte-identical to its backup. Leaving
instrumented source the running binary does not contain is the
source-and-binary-disagree trap this session has caught three times; a later
reader would find the logging in the tree and conclude it was live.
Also of note for the corpus: the header edit initially failed silently because I
chained it with `||`, which hid the failure -- the "assert every edit" lesson from
four iterations ago, repeated. Caught by grepping for the symbol afterwards rather
than by trusting the command.
The ramp write remains inferred, not observed. What is new is the reach: the
experiment is written and the obstacle is a build-tree path, not anything about
the game.

Two iterations ago I corrected MISSION.md's stale "🔴 Emulator-side questions are
blocked" banner and wrote, in its place, that the two items it named were
"unblocked, not answered ... both need a running menu, both now have one, and
neither has been attempted". I wrote that without reading either page.
Reading them:
8AX vs ptbase was RESOLVED on 2026-08-29. Its status line says so -- both its
questions closed, page kept for the evidence.
The gamma control was attempted and half-answered, and its page records that
the run "needed the emulator only to BOOT, not to reach a menu ... parked behind
the title-screen blocker for no reason".
So neither item ever needed a running menu, and the section's premise was wrong
independently of whether the menu was reachable.
All three clauses false. The failure is specific and worth naming precisely:
replacing a stale status with an UNCHECKED one, in the same edit that criticised
the document for carrying unchecked status. sylpheed-port wrote a dead instruction
inside the commit fixing dead instructions; this is that shape, one document over.
METHOD: a correction is a new claim and needs the same check as the claim it
replaces. The urge to correct supplies confidence the correction has not earned --
check a replacement as hard as the thing it replaces, and hardest when the edit is
about checking.

sylpheed-port's check-claims fails their run when a refuted claim is quoted
without an explicit token, and feeding it four withdrawals flagged three still
asserted unmarked -- each inside a correction they had written. REFUTED.md
publishes deaths without enforcing them, which is the gap I named last iteration
and did not close.
check_refuted.py is the prose equivalent: for each quoted claim in REFUTED.md it
searches docs/ for that text and reports occurrences whose neighbourhood carries
no refutation marker. Controlled first -- a claim planted unmarked in a scratch
file is detected, so a clean run means something.
9 raw hits, ZERO real revivals. All false positives, and the kinds are the
finding: 2 were text explicitly DECLINING to revive a claim; 1 a duplicate report;
4 were BACKLOG.md entries under a 2026-08-12 header, an append-only log recording
what was believed then; 2 were the claim quoted inside its own correction.
The structural limit is worth more than the clean result. A neighbourhood-language
detector cannot separate "asserted now" from "recorded as believed then", because
a dated log entry and a revival read identically. The port's design avoids this by
testing for a token an author must PLACE rather than for language -- theirs fires
correctly inside a correction, which is what caught their three, while mine fires
incorrectly there and would miss a revival reworded.
Stopped tuning at two remaining. Each marker phrase added fits the detector to this
corpus's habits of expression and away from being a test of them; tuning until it
reads zero would be fitting the instrument to the answer. Left over-reporting,
which is the safe direction.
Reach: it matches a claim's exact wording, so "no verbatim revival" is not "no
revival".

sylpheed-port audited the documents their brief names and found two stale
blockers in a table they are instructed to consult, having audited everything
else. Mine names eight documents; I had audited MISSION.md and never PROTOCOL,
REFUTED, INDEX or CONTAINER-NOTES.
REFUTED.md is the dangerous one, because a wrongly-dead entry stops someone
re-investigating something live. Checked the keyframe cluster first for the
opposite failure -- entries refuted USING the stale time association, which would
make their deaths unsound. They are sound: the additive-blend and pivot entries
rest on scale values and capture measurements that the association does not move,
and the one entry that did depend on it is already struck through.
The real gap is the other direction. EIGHT claims died this session -- the
fade-out duration "not in the file", the ~14 units as a black hold, the black
interval as a load, "(B) has no black interval", ptloop01/02 not free-running,
the splash dwells running 8.5 % long, EXTRAS's "structural" n=1, and the gap being
determined by the outgoing screen. Every one was recorded in its own page at the
time. NONE of them reached REFUTED.md, the file the brief says to grep before
proposing anything.
Added as a dated section with the true answer after each arrow, following the
file's stated format, and each carrying what made it wrong rather than only that
it was.
METHOD: a refutation that lives only where it was made is not reachable by the
person about to repeat it. The pages are where a refutation is argued; the index
is where it is found -- the same split as docs versus tool, and only the second
one saves anyone. The check is mechanical: after withdrawing a claim, grep
REFUTED.md for its noun.

after the fact by draw signature, which establishes THAT the two screens differ
but not WHICH either is, so the gap is attributed to a pair whose second member is
known only as "not the other one". Worth trying to remove.
Both runs saved a screenshot of the destination. Scored against the archives the
menu's non-EXTRAS buttons plausibly reach:
m2o best GP_OPTIONS 43.30, margin 5.88
m2o2 best GP_SYSTEM 45.74, margin 2.28
REJECTED against this corpus's own calibration. which_title_screen.py's control
puts a true match at RMSE ~18-20 with margin ~10, and a "neither" at ~34 with
margin under 1. These best fits are roughly double a real match. Accepting "m2o is
GP_OPTIONS" on a margin of 5.88 would be the same weak-margin acceptance that a
threshold was added to the navigation search to prevent three iterations ago.
Reach of the negative: one build per archive was rendered -- the default, which is
the largest -- and the screen a button opens need not be the largest build. So
this fails to identify rather than refuting those archives, which is a different
statement. The port's caveat stands and the ninth pair keeps it.
METHOD: a calibrated instrument can reject its own answer, and should. Without the
calibration, "best match, margin 5.88" reads like an identification -- a ranked
list always has a winner, and nothing in the ranking says whether the winner is
good enough. Any nearest-match report needs a known-good score beside it or it
will name something every time it is asked.

I have been reading MISSION.md every iteration as instructed and never once
audited it, while auditing headings, instructions, env vars and fallbacks
everywhere else. It carried three false section headings, each superseded in
HANDOFF.md and nowhere else:
"🔴 Emulator-side questions are blocked -- the title is not reachable here"
False. Twelve emulator runs on 2026-08-30 reached the settled title, gated
on the plate pulse, and drove it into the menu, EXTRAS and out of the
archive. The two items the section named -- the gamma control and
separating 8AX from ptbase -- are UNBLOCKED, not answered, and neither has
been attempted. That distinction is kept.
"🟡 Needs one more run -- a Japanese-locale capture", describing "one capture we
cannot take". Taken twice, both committed, via jp_title_session.sh. And both
questions it blocked are closed, one of them confirmed against that very
capture. ⚠️ I noticed this section was stale several iterations ago, said so
in a message, and did not fix it.
"🔵 Needs a human decision -- rotation". Decided and implemented the day it was
raised: HANDOFF records "OPTION A IS DONE. The reference renderer rotates",
and ui_layout.rs carries the rotated blit with a control test pinning 0° and
360° byte-identical to the unrotated path. The field is now confirmed from
the ORACLE too -- +30/-45 predicting AABB heights of 1135.3 and 1301.1
against 1134 and 1303 measured, both under 0.2 %.
All three corrected leading with the correction, originals quoted and demoted
beneath. Only FACTS were changed; the questions and their gates are untouched,
since keeping the document true is maintenance and changing what it asks would be
overstepping.
METHOD: audit the document that defines the objective, because it is the one
nobody audits. A document read only for instructions is never read for review, and
the more central it is the more often it is consulted and the less often checked.

sylpheed-port confirmed "nothing declared predicts the gap" from their export
independently, and deliberately declined to search combinations: four pairs
against many candidate two-screen functions fits by construction. Right call, and
it applies to me unchanged. So this iteration adds a PAIR rather than a fit.
menu -> a second screen outside GP_TITLE, reached by stepping the cursor two
items before arming. The button is not controlled -- there is no focus readout --
so the destination is identified afterwards by its draw signature: incoming
primitive [255] at 7-9 draws/frame, against the first run's [127] at 12-13.
Different screens.
Outgoing quad rises 25, 51, 102, 229, 255 across frames 37-42, then at frame 44
the new screen is already drawing. NO empty frame anywhere. GAP = 0.
So the menu as origin gives four values across four destinations: title 0,
EXTRAS 1, other-1 1, other-2 0. The same origin yields both 0 and 1 depending on
where it goes, while the two repeated pairs stay internally identical (3,3,3 and
2,2). Further evidence for the ordered pair over the origin.
Recorded as an observation with its counter-example rather than fitted: the
incoming screen's own full-screen primitive is [255] where the gap is 0 and [127]
where it is 1, which suggests a screen beginning from opaque black needs no blank
frame. That FAILS on menu -> EXTRAS, which declares a black backdrop and still
gives 1. Nine transitions against many candidate functions is the construction
the port declined to search, and I am not searching it either.

Two things in one run, on the screen that motivated both.
First, the effective-config guard I had flagged as "not yet verified" -- leaving a
doubt in my own file, which is the shape sylpheed-port had just caught themselves
in. Verified now:
arming on = menu [screen_id: cannot separate menu/EXTRAS]
discriminator = extras rmse=18.94 (other main_menu 30.09, margin 11.15)
Before the fix this run would have announced "arming on = menu" while armed on
EXTRAS. The ambiguity is visible instead of hidden.
Second, a replicate of the table's weakest cell. Second EXTRAS -> menu: outgoing
quad 229, 255, 255 across frames 29-31, then TWO empty frames at 32 and 33. Gap =
2, identical to the first.
Eight transitions now say something sharper than the outgoing-screen story, which
is superseded a second time:
title -> menu 3, 3, 3 n=3 repeats agree
EXTRAS -> menu 2, 2 n=2 repeats agree
menu -> title 0 n=1
menu -> EXTRAS 1 n=1
menu -> other 1 n=1
EXTRAS -> other 3 n=1
Every repeated pair is identical -- five replicates, no variation -- and every
differing value comes from a different pair. The same origin gives different
values to different destinations (menu 0 vs 1, EXTRAS 2 vs 3). So the origin
CONSTRAINS the gap and the ORDERED PAIR determines it, reproducibly.
For the port: a constant black_hold_units is excluded and keying on the outgoing
screen is excluded too. Any keyed version must be keyed on the ordered pair, with
a measured value per pair -- six known, two replicated, none predicted by anything
declared.

sylpheed-port promoted my unverified "EXTRAS is stuck at n=1, a structural limit"
out of a message into DECISIONS.md as an established fact, while holding the file
that refuted it -- their own authored/flow.json, recording ptbtn11 ->
GP_MISSION_SELECT. Their corollary is sharper than my original entry: distrust
"structural" and "impossible" hardest when SOMEONE ELSE writes them, because they
arrive without the doubt the author would have had.
Swept this side for the same shape. It is clean: port-supplied figures are
attributed in the text ("port reports 866 keyframes ... 0 untimed"), the
ui_layout.rs comment on the unreachable fallback cites MY OWN measurement of 0
untimed of 24 811 across 965 builds rather than their 866, and their quantisation
floor of 0.41 appears in no document of mine at all.
Reach stated: this tests attribution WORDING and the port-supplied figures I could
enumerate, not every reliance. A negative from a naive check is not proof of
absence, and saying so is the point of recording it.
What protected it was a habit rather than vigilance -- writing the source into the
sentence. That is now the third instance of one remedy: state what the number is a
number of; write the index space into the token (e10 rather than "build 10"); write
the source into the claim. Put the qualifier in the text, never in the reader's
memory.
Also fixes the half-guard the port called out. The effective-config block reported
`arming on` from screen_id.py, which cannot separate the main menu from EXTRAS --
so it announced "menu" while the run was armed on EXTRAS, a field the guard could
not resolve for exactly the two screens in question. It now prints both that value
AND the discriminator with its margin, so the ambiguity is visible rather than
hidden. NOT yet verified in a run -- per the port's own --no-hold lesson, parsed
and edited is not working.

I recorded EXTRAS as able to supply only one gap measurement because "its sole
exit is (B) to the menu", and called that n=1 STRUCTURAL -- a word that retires a
question. The disc refutes it in one command: build 6 declares three buttons,
ptbtn11/ptbtn12/ptbtn13, all kind 0x3002. The cap was an unverified assertion I
had already written into HANDOFF twice.
Measured EXTRAS -> a screen outside GP_TITLE via (A): outgoing quad rises across
frames 36-40 (4-5 frames, matching build 6's declared 10-unit close), then THREE
empty frames at 42, 43, 44, then a different archive builds (23-28 draws/frame
against GP_TITLE's 11-14). Gap = 3.
So EXTRAS as outgoing gives {2, 3}, and seven transitions now group as:
menu {0,1,1} n=3, EXTRAS {2,3} n=2, title {3,3,3} n=3.
A pairwise control that holds the destination class constant: menu -> another
archive gives 1, EXTRAS -> another archive gives 3. Same kind of destination, gap
differs by outgoing screen. That is the strongest support yet for the
outgoing-screen dependence because it removes the destination as the variable.
But the clean ordering is GONE: EXTRAS {2,3} and title {3,3,3} overlap at 3, so
"menu < EXTRAS < title" no longer separates them. What survives is weaker -- the
outgoing screen constrains the gap to a ~2-wide band and the bands are not
disjoint.
METHOD: a structural limit is a claim and needs checking like any other.
"Structural" and "impossible" are the two words most worth distrusting in your own
notes, because they retire a question rather than answering it and nothing later
re-opens them.

sylpheed-port's BLOCKED row asks for a second value on one outgoing screen --
what would make "the gap tracks the outgoing screen" predictive rather than a
restatement of the data.
First, a correction their ask surfaced without needing a run: THE MENU ALREADY
HAD TWO VALUES AND THEY DIFFER -- 0 leaving for the title, 1 leaving for EXTRAS.
So "the outgoing screen determines the gap" was too strong and is withdrawn; what
holds is an ordering, not a determination. Also recorded: their ask is answerable
only from the menu, since the title's sole exit is (A) to the menu and EXTRAS's
sole exit is (B) to the menu.
Then took a third menu-outgoing measurement, to a screen outside GP_TITLE.
Confound named in advance rather than after: that transition leaves the ARCHIVE,
so a pak load could inflate the gap for reasons unrelated to the outgoing screen.
Result: outgoing quad rises across frames 24-28 (4-5 frames, matching build 5's
declared 10-unit close), then ONE empty frame at 30. Gap = 1, identical to
menu -> EXTRAS. So the confound is measured ABSENT -- leaving the archive costs no
extra black, which is worth having on its own.
Six transitions now group as: menu {0, 1, 1} over three different destinations
including another pak, EXTRAS {2}, title {3, 3, 3}. The ordering rests on 3+1+3
measurements and the menu's three agree to within one frame.
Still not predictive: outgoing closes are 5, 5, 4 frames against gaps {0,1}, {2},
{3}, and EXTRAS has n=1 with no way to obtain a second value.

Applied my own log-line rule to my own instrument first, which is the "rule
written down is not a rule applied" failure I have on record three times. Every
branch of fade_decompose.sh now announces its EFFECTIVE configuration -- derived
from the variables in force, not from $WHERE, per sylpheed-port's sharpening --
and the run REFUSES if no branch announced itself. That is the guard that would
have caught last iteration's silent fall-through at a glance.
With it in place, took the measurement that failed last time: menu -> EXTRAS, the
reverse of the pair measured at a 2-frame gap. Navigation verified both ways
(extras margin 11.23, back on menu 11.60) and the config block confirmed the right
branch.
Result: outgoing quad rises across 5 frames matching build 5's declared 10-unit
close, then ONE logged empty frame. Quoted as 1 with an upward uncertainty, since
its two neighbours carry no frame header at all.
Five transitions now order by the screen being LEFT:
menu -> title (B) 0 outgoing menu
menu -> EXTRAS (A) 1 outgoing menu
EXTRAS -> menu (B) 2 outgoing EXTRAS
title -> menu (A) x3 3,3,3 outgoing title
Direction is ruled out: EXTRAS->menu (2) and menu->EXTRAS (1) are the same pair
both ways and differ. Button is ruled out: (B) gives 0 and 2, (A) gives 1 and 3.
Incoming screen is ruled out: an incoming menu takes 3 from the title and 2 from
EXTRAS.
NOT a rule, and recorded as such. Three outgoing screens with one value each means
"each outgoing screen has its own gap" restates the data rather than predicting,
and nothing declared predicts it -- outgoing closes are 5,5,5,4 frames against
gaps 0/1,2,3, inverted if anything, on three points.
What it changes for the port: a UNIFORM black_hold_units is now positively
excluded rather than merely unsupported.

Set out to measure menu -> EXTRAS, the reverse of the pair measured at a 2-frame
gap, to test whether the black gap is a property of the screen pair or of the
direction. The run did not do that.
A three-part patch to fade_decompose.sh asserted two of its three replacements
and left the third -- the branch condition -- unchecked. It silently failed, so
WHERE=menu2extras fell through to the `title` branch. The capture is well-formed
and is of a different transition than intended, which is the build-ordinal error's
shape again: right-looking output for the wrong object. What caught it was the log
LACKING the navigation lines the intended branch prints; the data itself looked
entirely fine.
Salvaged, because the accidental transition is one already measured twice:
run outgoing ramp black incoming decay
1 67-70: 63,127,191,255 3 73-77
2 64-67: 63,127,191,255 3 70-74
3 92-95: 63,127,191,255 3 98-103
Three independent runs, gap = 3 frames every time, outgoing ramp byte-identical
in all three. That takes "the black gap is not a load" from two replicates to
three, and makes the 4-frame outgoing ramp as solid as anything measured here.
menu -> EXTRAS remains open; the condition is fixed (with an assertion this time)
and the run has not been taken.
METHOD gains two entries. Assert every edit, not most of them -- and have each
branch announce itself in the log, so a run that took the wrong path says so
before its numbers are read. And: "appears nowhere in crates/" is a claim about a
TREE. sylpheed-port found SYLPHEED_KF_TIME_SHIFT live at ui_layout.rs:497 on their
branch, which carries the stale era; both statements are true of different trees.
With main 145 commits behind and each agent on a topic branch, any claim about
what the code contains needs its ref attached.

sylpheed-port inverted my documented->exists sweep into parsed->documented and
found three live undocumented flags, with the framing that a capability existing
only in an 11 000-line record is, to a reader of the interface, a capability that
does not exist. The mirror on my side is env vars the CODE reads, checked against
the docs. Like theirs it enumerates, so it completes rather than samples.
41 read by crates/, 19 documented, 22 not. The 22 split cleanly: 7 are read only
in examples/ (per-example filters and dump paths, reachable only by editing an
example's command line), and 15 are read in src/ -- live capabilities of the
library and CLI. Ten are mesh/3D toggles and five are XPR_* texture-decode
toggles.
FOR THE PORT: none of the 15 is in the UI path. Every env var ui_layout.rs and
the screen commands read is documented -- SYLPHEED_REST_RULE and
SYLPHEED_KF_TIME_LEGACY. The menu lane is clean in this direction. But the five
XPR_* are texture-decode toggles and the port consumes textures, so if a sprite
comparison ever disagrees those are the knobs and they are invisible from the
interface.
LIMIT, stated rather than glossed: I verified NONE of the 15 end to end.
`texture export` takes a loose file and the disc keeps its textures inside paks,
so the check cost more than the answer was worth here. That matters because the
port found --no-hold parsed, documented AND INERT under an interaction with
--time: "parsed and reachable" is not "works". The honest claim is that 15
undocumented env vars are READ, not that 15 capabilities exist.
METHOD: sweep the surface in both directions, and note that both directions
enumerate and therefore complete rather than sample -- rare enough in that file to
be worth preferring when available -- while neither establishes that the thing
works.

The refinement sylpheed-port earned by sweeping their own instruction surface and
finding all of it loud: a wrong path errors out and announces itself, while an
inert environment variable returns a clean, wrong result. Only the silent kind
manufactures evidence.
Records that the silent surface is ENUMERABLE and therefore sweepable rather than
sampleable -- every env var the docs name, checked against the code -- with the
result of doing it, and the proxy warning that absent-from-code also flags
container paths the brief sets and no code reads.
This entry failed to apply in the previous commit (an exact-match assertion on
surrounding text) while the two document fixes it describes did land. Committed
separately rather than amended.

sylpheed-port refined my ranking: rank silent instructions above loud ones. All
of theirs were loud -- wrong paths that error out and announce themselves --
while mine was silent: an inert env var returning a clean, wrong result. Only the
silent kind manufactures evidence.
The silent surface is enumerable, so this is a sweep rather than a sample: every
environment variable the docs name, checked against the code.
SYLPHEED_KF_TIME_SHIFT was still live in FIVE doc files after I fixed one last
iteration. Two of the five were genuine hits rather than historical quotes:
ui-resting-pose.md -- a RESULTS TABLE ROW labelled "with
SYLPHEED_KF_TIME_SHIFT=1". Re-running it sets an inert variable, produces the
DEFAULT row, and lets a reader conclude the two readings agree. A stale
instruction inside a results table is the purest form of the evidence-
manufacturing class.
HANDOFF.md -- "experiment reachable via SYLPHEED_KF_TIME_SHIFT=1", a live
instruction in the delivery contract.
And a live gate exists under a DIFFERENT NAME that the docs never pointed at:
SYLPHEED_KF_TIME_LEGACY, verified read at ui_layout.rs:595 -- the parser itself,
not only the tests, so it does reach screen info and screen render. Both hits now
redirect there.
Beware the proxy, which is the trap the port named about their own "parsed"
check: absent-from-code also flags SYLPHEED_DISC, XENIA_SRC and SYLPH_ISO, which
are container paths the brief sets and no code reads. Absent-from-code is
necessary, not sufficient, and I checked each rather than reporting the seven raw
hits.
