e6c78b9a04 re: the relay loop is measured, and a cross-convention collision found
Re-ran the peer cross-scan with their known-positive assertion and my earlier count
was wrong. Third phantom reader in one session: a second parse of the same file in
the same minute returned a clean table with total 0, because their register rows
are bare phrases and that parse searched each row for a quoted string. My first
parse worked only by falling back to the whole line.

Real count: 11 occurrences of their 12 registered claims in my corpus. Three of
them are in the file I wrote to report on their claims -- so I produced the relay
loop they described while documenting it, and the effect is now measured rather
than asserted.

New: a cross-convention collision. '1 of 3 streams' is a dead claim in their
register and a live warning in mine -- both my occurrences read that the warning
STANDS. Not a revival; two corpora using the same words for different propositions.
That is the strongest argument yet for keeping cross-agent checks advisory, and it
is an instance rather than a worry.

4f32850059 re: cross-scan the peer register -- none of their refuted claims is live in my corpus
They asked in the right form after their own 'latent, not active' turned out to be
a stale-copy artefact. My version: zero of my registered claims appear in their
files, from my tree AND from their branch head, controlled with a live probe
because a zero from a broken reader looks identical.

Then the part they left to me. My first reader of their register was broken and
returned a false zero: I regexed quoted strings out of their script and got 63
phantom phrases. The register is a heredoc of 12 rows. Parsing it properly finds 3
of their claims in my files, across 4 locations -- one of which is my stale copy of
their own BLOCKED.md and not mine to judge.

None is a live revival. Every one sits on a page whose subject is the corrections
themselves, which is what they predicted without asserting.

Their restraint is the transferable part: their first fix counted the six as
failures, applying their [refuted] convention to a corpus that marks corrections
its own way.

7863157040 method: a checker inherits the staleness of every file it scans

bef068479e tools: check_refuted now says when it judged a peer-owned file from a stale copy
It scans all of docs/, which includes files sylpheed-port authors, and my copies of
those come from main -- six of seven are days behind their branch head and one I do
not have at all. So a verdict here about one of their files is a verdict about my
stale copy.

The direction that matters is the false positive, and it is not hypothetical: on
2026-08-31 I did it by hand, telling them a BLOCKED.md row was wrong when it had
been struck for days, with their live file one git show away in a ref already
fetched here.

Reported, not excluded. Skipping their files silently would hide the exposure, and
being behind a peer's topic branch is the normal state -- making it an error would
be scenery within a day, which is sylpheed-port's call on their own peer-head tool
and the right one.

Zero hits land in those files today, so this is latent rather than active. Selftest
and the real run both still exit 0.

f3fe40a6a0 handoff: withdraw the instruction to check a BLOCKED row that was already corrected
The finding stands -- my own page said the menu's bank was undecodable from the disc
while decoding it three ways lower down. The instruction did not: I told the port to
check a row that had been struck for days, because I read my checkout's 2026-08-29
copy of their file instead of their branch head.

ffc5fbfa81 method: read the peer's branch, not your checkout's stale copy of their file
I reported a defect in the port's BLOCKED.md that had been struck and corrected for
days, and whose correction already contained the diagnosis I thought I had found
independently. I was reading my working tree's copy, last touched 2026-08-29 and
234 commits behind, while their live file sits on auto/port-p6-audio -- a ref
already fetched in this checkout and readable with one git show.

The exact mirror of the gap I had been reporting about them. They read main's stale
HANDOFF while mine was on my branch; I diagnosed that as needing a human merge, then
made the same error in the other direction with the fix one command away. They had
already been reading my branch directly, citing my commits by sha. I had not been
reading theirs.

So the shared-state problem is two gaps, not one, and only the second needs a merge:
what a peer HOLDS is readable now from any topic branch; what a peer must be TOLD
still needs main.

9bacd69f6c re: bgm-two-stems.md said the menu's bank is undecodable from the disc, and its own page decodes it
The Status line and the section heading both read 'undecodable from the disc' while
a later section of the same page decodes it three ways, one of them static from the
executable -- GamePart_Title's handler does li r5, 1103. A reader who stops at the
top concludes the opposite of what the page establishes.

The surviving content is the reason the CUE TABLE cannot answer it: 32 BGM cues
named by number with no screen name, with SOUNDS, FILES and the bank headers all
searched. A negative about one search location, written as a negative about the
disc -- the same method-versus-subject error as the SE-audio heading, in the first
line a reader sees.

It propagated: the port's BLOCKED.md carries 'which BGM the menu plays -- not on
the disc' in the same words.

Found by applying sylpheed-port's 'get the category right' discipline to my own
noisy impossibility sweep, after measuring what the false positives actually were
rather than assuming they were infrastructural.

e6f929409b re: GP_TITLE holds exactly three button screens, and EXTRAS is the only internal destination
Serves Q6's open question. boot-config-and-gamepart-registry.md records a
count-match for the title part's event numbers -- four menu items load an external
archive, EXTRAS stays inside GP_TITLE -- explicitly as an observation rather than a
decode. Half of it is disc-checkable and now has support.

Every button record in all 16 GP_TITLE entries: ptbtn00 (the plate), ptbtn01..05
(main menu), ptbtn11..13 (EXTRAS). No fourth button screen, so no DIFFICULTY build,
and DIFFICULTY is what NEW GAME opens. The other four destinations have their own
paks -- GP_OPTIONS, GP_SAVE_LOAD, GP_TUTORIAL -- while EXTRAS' two children are
GP_MISSION_SELECT and GP_MOVIE_THEATER, so EXTRAS is internal and its children are
not.

Still NOT a decode of the event numbers: the shape the count-match asserts is real
on the disc, but nothing shows a given event is a given row.

Negative recorded with its reach: DIFFICULTY's build is not located. I searched for
an 8-button-record build on the assumption its four items pair with f variants, as
GP_TITLE's screens do. They may not, so the negative is narrower than 'not found'.

56ba2ea4f3 tools: ring_row gets a self-test, which found that a TITLE frame reads as NEW GAME
sylpheed-port closed their last harness gap on a control that never asked whether
the measurement was LIVE -- an empty band list made identity and the real pair both
pass. Applying that to ring_row.py, which underpins every focus finding I have made
and had no self-test at all.

It found a real defect immediately: main_menu_item(ring_row(f)) is not None was
being used as a main-menu test, and on a TITLE frame the gutter carries a bright
cluster at y=243, inside tolerance of row 0, so the title reads as NEW GAME. Glyph
714 against the menu's 327 separates them cleanly; the ring row alone does not.

It never misfired in the sweeps, because B from a submenu goes to the menu rather
than the title -- the test was simply weaker than it was being trusted to be. Added
is_main_menu(), which requires the row AND the glyph signature, and the sweep's two
menu tests now use it.

The self-test asserts the defect it guards, and includes a liveness case: a blanked
frame must return None rather than a number.

d48781262e re: menu focus does not survive a reboot -- six fresh boots, three following a session that ended elsewhere
No new boot was spent: six runs had already captured the first menu entry of a
fresh boot, and all six read NEW GAME. Three of them follow a session that ended
with the cursor on EXTRAS or OPTIONS, which is what makes it a test of persistence
rather than a repeated observation.

Reach stated rather than implied: every session ends with the emulator KILLED, so a
game that writes menu state on a clean shutdown would never get the chance. This
measures 'does not survive a killed session'.

Refutation attempt on the port's extras/initial_focus: ptbtn11 -- it SURVIVES.
ptbtn11 is the top button on the EXTRAS build, with the main menu as a control
where ptbtn01 is top and is known to be NEW GAME.

Incidentally corrects ring_row.py's stated calibration. It cited capture_y = 49.5 +
1.060*design_y, fitted against menu_focus.py's row centres, which are NOT the
disc's button rows -- the disc says 162/242/322/401/482, spacing 80, and
menu_focus.py drifts up to 17 px against them. Re-fitted: 64.82 + 0.9919*design_y,
residuals under 0.7 px. No item assignment changes.

abeea3b834 re: settled -- a submenu resets to the item it OPENS on, not to its top item
DIFFICULTY is the screen that separates the readings: it opens on NORMAL, second of
EASY/NORMAL/HARD/BACK. Reproduced on a fresh boot rather than inherited from the
2026-08-29 capture. After one confirmed DOWN to HARD, B out and A back in, it
returns to NORMAL -- in-cursor 1.0 from opened against 93.9 from where left.

So reset targets a per-screen opening default that need not be the first item. The
other four submenus could not settle it because on each of them the opening item IS
the first, so both readings predict the same observation.

sylpheed-port's refusal to promote 4/4 to a rule was right on the evidence: a
generalisation from those four would have got this fifth screen wrong.

The probe never presses A inside a submenu, so it cannot reach SELECT DATA and the
guest throw at PC 0x82307128 -- recorded in the tool's source.

308d89c215 tools: let the submenu sweep target NEW GAME, for the DIFFICULTY reset question
DIFFICULTY opens on NORMAL, the second of four, so it is the screen that separates
'resets to the named item' from 'resets to the top item' -- the question
sylpheed-port has had open for several iterations.

The probe is safe on this path without modification: it presses A to enter, one
DOWN, then B to leave, and never presses A inside a submenu, so it cannot reach
SELECT DATA and the guest throw at PC 0x82307128. Noted in the source so nobody
adds one.

94919e81b1 re: DIFFICULTY opens on NORMAL -- the non-first opening item, already in the corpus
sylpheed-port has been asking for a submenu whose opening item is not its first,
because that separates 'resets to the named item' from 'resets to the top item'. I
told them none of the screens I measured was one, while line 248 of the page I was
editing records DIFFICULTY as opening focused on NORMAL, the second of four.

Provenance is clean: the run drove NEW GAME with no d-pad, the screen sat unchanged
for 90 s, and s00a-drive-blocked-by-focus.md confirms the step matched the committed
capture at r=+0.999.

So 'a screen opens on its first item' is refuted as a general description, and the
distinction is real in this game rather than academic -- on EXTRAS, TUTORIAL and
OPTIONS the two readings coincide only by accident.

It does not settle their question, which is about reset rather than opening. That
needs one experiment on DIFFICULTY, going back rather than forward, since its
forward path crashes the guest.

The failure is mine: I searched among the screens I was measuring and never grepped
the page I was editing.

b2a2c6a834 tools: assert the scan boundary in check_refuted's self-test
sylpheed-port's point: a control that runs where the tool does not look proves
nothing about the tool. Case 2 plants a revival INSIDE the scanned root and demands
exit 1; a new case plants the same text OUTSIDE it and demands exit 0. The pair
asserts the scan boundary is real rather than leaving it to be reasoned about --
which is how I had it, correctly but only in my head.

Verified first by hand: identical plant text gives exit 1 inside the root and 0
outside it. Five cases now, all passing, and the real corpus still runs clean.

4b8afbe85e re: all four measured submenus reset -- the main menu is the only screen that remembers
LOAD GAME, TUTORIAL and OPTIONS all reset on re-entry, joining EXTRAS. With the
main menu persisting, the rule is four of four submenus resetting and one
exception -- the opposite of what a single screen had suggested.

Fourth attempt, and every control in it is a previous failure: the decision uses
the cursor's own region so no per-screen geometry is assumed (sweep 1 read the main
menu's gutter on screens whose cursors are elsewhere); the back-on-the-menu test is
the narrow ring row (sweep 2 died when a crash dialog defeated whole-frame
comparison); absolute row checks after every press (a constant offset passes a
differential control); and a two-sided self-test that constructs both verdicts,
which had already caught a rule I broke myself.

Screens confirmed by eye and committed as evidence, because an earlier run was
fooled about which screen it was on. LOAD GAME's 21.6 is explained by its list
scrolling rather than moving a ring.

Still not separated: resets-to-named-item vs resets-to-top-item. None of these
three has an opening item that is not its first.

571d7e87b0 tools: let the submenu sweep's self-test be checked without starting a run
Verifying it previously meant launching the script, which then waits ~150 s for a
main menu and opens x11grab captures -- so the question "did the self-test pass?"
could not be answered without disturbing whatever else was using the display. That
is how a check-the-tool step turned into competing load during a measurement once
already.

244648ae97 tools: check_refuted gets a harness self-test, which found it could not fail on an empty register
sylpheed-port closed this gap first: their controls asserted failure-on-perturbation
but nothing asserted that a BROKEN harness reports broken. Their stub is a check
that cannot fail; the equivalent here is a register that loaded no claims, which
reported clean forever.

The self-test drives the REAL machinery over synthetic corpora as subprocesses and
reads actual exit codes -- their first version reasoned about what the machinery
would do instead of running it, which is the error this whole thread is about
committed inside the tool built to prevent it.

Four cases, all passing: clean corpus 0, verbatim revival 1, marked revival 0, and
empty register 2. The fourth was a real hole, not a modelled one: the tool now
refuses instead of passing when it parses no claims. Exit convention is theirs --
0 fine, 1 a real check failed, 2 the harness is broken.

Also confirms the real corpus still runs clean at exit 0.

5ec4244c18 re: third submenu sweep void -- the self-test caught a fault I introduced myself
The rework was sound and controlled. The run died because I edited and
deliberately broke the sweep script while its own run was in flight, and the sweep
read the script at its start, which fell in that window.

The self-test refused to run: constructed PERSISTS came back RESETS. Without it the
sweep would have reported RESETS for all three screens -- confident, uniform and
fabricated. First save, on the day it was written.

Three further self-inflicted faults recorded: a competing x11grab during a
measurement (the concurrency confound the port warned of), a pkill -f that can kill
the running sweep's own capture, and a restore that sat as the last line of a
timed-out command so it never ran. The process fix is to commit the tool before
running it.

732907e5e1 tools: submenu sweep gets a cursor-region rule and a two-sided self-test
Sweep 1 failed because ring_row scans the MAIN MENU's gutter and these screens put
their cursors elsewhere; sweep 2 failed because a whole-frame identity test cannot
match once a crash dialog covers the centre. This rework fixes both: the decision
uses the region that CHANGED when the cursor moved, so no per-screen geometry is
assumed, and the back-on-the-menu test is the narrow ring row, which is what kept
reading correctly under the dialog.

The self-test is sylpheed-port's sharpened rule -- a control must construct the
failure it is named after. Mine was one-sided: I checked only that the rule reports
RESETS on a known-RESETS triple, so a rule biased entirely to RESETS would have
passed. It now constructs both verdicts from the same frames and exits 3 if either
is wrong.

Committed BEFORE running, which is the process fix: the previous run aborted
because I was editing and deliberately breaking this file while its own run was in
flight, and the sweep read the broken version.

d46f5546dc correction: the previous commit message lost three words to shell substitution
Commit b/HEAD~1's body reads "a  swallowed the verdict". It should read "a
`return 0` swallowed the band verdict" -- the backticked text was command
substitution inside a double-quoted -m, so bash executed it and spliced in the
empty result, and "band" went with it.

This is the second instance across two agents: sylpheed-port reported the same
thing days ago and left it uncorrected because it was pushed. The property that
makes it dangerous is theirs to name -- a dropped noun leaves grammar intact, so
the sentence still parses and nothing looks wrong.

Recorded as an empty commit rather than a rewrite, because the history is shared
and rewriting it is forbidden.

Now: unmarked assertions exit 1; a failed control exits 2. Suppressed mentions do

A 1 s misalignment costs 0.16 dB against their 0.66 dB pass band, so the
alignment-free claim holds. Two caveats measured: at 10 s it reaches 1.00 dB, since
a fixed window covers different material once the shift is large; and the
separation floor is material-dependent -- two unrelated music banks give 5.28 dB
where an unrelated movie gave them 19-20, so the threshold's margin depends on the
known-negative chosen.

3d9309dace re: sweep for negatives stated as world-properties -- the tool failed its control twice first
The mission's third classification is 'undecodable, with reach', and a negative
written about the subject when it is about the method is the failure that put 'an
individual SE's audio is not extractable yet' at the head of a page whose own later
section located the waves.

The tool failed its control -- the one known instance -- twice. First the pattern
required a sentence-ending period, and headings do not end in periods, so it matched
nothing in any heading and a clean report would have been vacuous. Then the scoring
hid it, because 'yet' was in my list of scope words. It is not one: 'yet' and 'so
far' are temporal hedges naming no instrument, no search and no place looked, which
is exactly what made that heading read as bounded.

With the control passing, the two amplifier files are clean: every INDEX and HANDOFF
hit read, all legitimate. 130 unscoped candidates remain unread corpus-wide, and the
regex has a high false-positive rate -- recorded as reach, not as a clean bill.

b410c94445 re: run the identity control on the coherence estimator -- it is exact, and the refutation strengthens
sylpheed-port disqualified a difference instrument of their own and named the rule:
before asking whether an instrument can measure a difference, ask whether it
returns zero for no difference. Mine had never had that test -- its positive
control was a filtered copy at 0.94, which I had taken as the ceiling.

Identity reads 1.0000 in every band, and a linear filter with NO delay also reads
1.0000. The 0.94 was entirely the 12 ms delay's windowing cost. So the ceiling for
a filtered copy is 1.0 and the measured 0.027 midrange is further from it than the
original control implied.

It also adds an argument the first pass missed: a delay depresses coherence
uniformly (0.9288..0.9380 flat), while the measurement is 0.027 midrange against
0.83 at HF. The shape is inconsistent with a delayed filtered copy too, which was
the remaining route by which a rear pair could have produced it.

I told them two BLOCKED rows were stale. One was. Their skip row reads '(a)
ANSWERED, (b) still open' and cites Q9; (b) is a different question and the 🟡
carries it correctly. I read an emoji and inferred a status, which is the same
error as leaving a stale row live -- and the error this audit is about. They
pushed back rather than accepting it, which was right.

d38adcf64a handoff: stop the forward markers duplicating headings -- a duplicate disarmed a check
sylpheed-port's contract-check perturbs the FIRST occurrence of an anchor. My
supersession marker quoted the 'EXTRAS resets, the main menu persists' heading
verbatim, so the sentence appeared twice and the control read the untouched
duplicate and passed a wrong contract.

The marker existed because they had told me a grep lands mid-document, so the fix
for one navigation problem created another. Pointers now name their targets by date
and subject instead of reproducing the heading.

c43714363d re: menu-audio-cues.md contradicted itself -- a negative about the method read as one about the audio
Its line 81 headed 'an individual SE's audio is not extractable yet' while line 189
of the same page says the waves are located and the port can have the audio. The
surviving content is the reason Static.slb resists STATIC scanning -- no RIFF/seek/
WAVE delimiters -- which is why the extraction had to be dynamic. The heading
generalised that into a claim about the audio.

Marked rather than deleted, since it is the evidence for why the route had to be
dynamic. INDEX was still quoting the wrong form of it days later.

3f627eeeb4 re: first audit of INDEX against the pages it links -- 3 of 8 rows were stale
INDEX is read every iteration and is the first thing a new reader meets, and I had
admitted three times to never auditing it. Found by accident: I was about to spend
a boot measuring whether A skips a movie because INDEX said 🟡, when movie-binding.md
had it settled since 2026-08-28 with a three-boot baseline and a delivery counter,
and HANDOFF carried it correctly. The staleness was in the index alone.

Three stale rows fixed: movie skippability, SE audio extractability, and B leaving
the main menu. Five other hits read and left alone -- index and page were talking
about different clauses.

One of the three should have been caught by check_refuted.py: REFUTED holds the
same dead claim with a different second clause, and the register matches exact
wording. Its docstring documents that weakness; this is the first live instance.

Also flags a within-page contradiction not fixed here: menu-audio-cues.md line 81
still heads a section saying SE audio is not extractable, which its own line 189
refutes.

72f0f7fcea re: reproduce the container-seek trap on this disc, and clear the Explorer of it
sylpheed-port asked whether my capture or extraction paths seek with -ss before -i.
Reproduced on this disc's own movies: a 4.0 s audio request returns 4.597 s (ADV)
and 4.256 s (S00A), with correlations of -0.03 and -0.34 at zero shift, so the
windows are different content rather than shifted. The 4.597 matches their 4.6.

But the VIDEO seek here is exact -- container-seek frame at 20.0 s is byte-identical
to the frame from a full decode with no seek. So the trap is a property of the audio
stream, not of -ss placement as such.

The Explorer has two -ss sites, both video, and its audio path (decode_audio_wav)
never seeks -- so it is not affected. Read only; the viewer is the human's tool and
was not modified.

My own instrument failed twice first: a vstats line read as a timestamp, then
showinfo reporting frames from before an output-side -ss discard. The pixel
comparison needed no interpretation and settled it.

ac6d218373 re: both routes to the frame clock are blocked, and my no-PulseAudio claim was wrong
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.

7a72c1a5fa re: strike the resolution contrast and the skipping claim -- both refuted by the port's own probe
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.

40cf9b5025 method: land the pacing re-correction itself
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.

5eabcf07b0 method: re-correct the pacing entry -- their argument was wrong, my original reading was right
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.

arriving by grep needs to know it was superseded.

667b4264f0 method: correct my characterisation of the port's pacing test -- the overrun is the evidence
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.
