The two adjacent pairs with identical element sets split. 0/1 are the same 59 810
bytes stored twice -- a duplicate, not a language pair. 2/3, the DIFFICULTY build,
differ in size and in 2.77 % of bytes from offset 0x1BB while sharing every element
name, which is what a language pair looks like.
Control: entries 10/11, known to be two different dialogs, differ in 54.90 % of the
common prefix, so the comparator separates unrelated dialogs.
Supported, not proven, with the untested step named: I have not captured DIFFICULTY
in ja. That the two are ENGLISH and JAPANESE rests on the disc's convention, not on
a capture of this screen. This partially restores a claim I withdrew, at lower
strength than the original phrasing.
Also records a refutation attempt on the port's BGM_103 exclusion: it survives and
is tighter than they stated -- of 32 census rows, exactly one bank carries EITHER
wave size, not merely both.

sylpheed-port found the tell for decorative legs -- claims announcing their own leg
count -- and their audio.json case had two of three legs turn out to be one
disc-to-runtime comparison. Ran it here and my DIFFICULTY delivery has the same
shape.
The image leg says DIFFICULTY is a dialog and names no entry. The disc and oracle
legs are one compound argument, since the capture is compared against the disc's
rows. What makes that discriminating is the exclusion scan -- zero rival builds
disc-wide -- which is exactly what the word 'three' was taking credit for.
Corrected in place to state the reasoning rather than the count. The conclusion is
unchanged; the evidence is two arguments, not three.
Reach: 1 of 272 leg-count claims audited. One verified case is not a verified set.

sylpheed-port re-ran my closing of the 37 and one of its two legs fails. I wrote
that sprite counts differ between adjacent stage-title dialogs; 12/13 is equal,
thirteen each, and it is visible in my own printed output which I generalised from
the 10/11 example beside it. Our absolute numbers also disagreed because we counted
different things and I did not say which I meant.
The conclusion is untouched -- the stage numbers settle it alone. The shape is the
point: the leg carrying no weight is the one that went unchecked, which is the
EN/JP pair failure one step out, committed while writing up that very failure.
Also records that a conclusion with two supports reads as better evidenced than one
with a single support, so a decorative support makes the appearance of redundancy
itself misleading.

Both agents left the language reading standing for the 37 pairs that differ without
a button-count mismatch, and both observed that nothing rewarded closing it. Two
scans closed it, against my own reading.
All 39 equal-button-count pairs share button names and rows exactly, which does not
settle it -- two dialogs sharing a button template look identical by that test. What
differs does settle it: pzstg10 against pzstg02, pzstg11 against pzstg03, pzstg12
against pzstg13. These are the DLG_STAGE_TITLE01..16 dialogs and an adjacent pair
carries two different stages, with different sprite counts, which is a different
amount of text rather than a translation of the same text.
So the whole 63 is explained by one fact -- adjacent entries are unrelated dialogs
-- with no residue. The 2 identical pairs remain unexplained but are no longer
anomalous against a hypothesis, because the hypothesis is gone.
Recorded about process rather than the disc: a bound nobody is incentivised to test
is exactly where a convenient claim survives, and the next reader cannot tell
whether a bound was respected or merely never revisited.

sylpheed-port named the mechanism after copying an unchecked aside of mine into an
authored file twice, inside the same why that carefully said their re-derivation
does not name the screen. Scrutiny goes where the weight is, so a claim carrying no
weight attracts none, and then it reads as measured.
Swept this corpus for the shape and found one in the port's own domain.
ui-composable-bundles.md said a .prm element 'has no sprite and is skipped as
everywhere else'. True of our compositor, false of the game: the element is
palogo_eff0.prm, which ui-forced-backdrop.md decodes as the full-screen opaque
black backdrop, forced first, measured off the running game. The page's
load-bearing draw order was pinned by a disc test and checked; the aside was not.
The generalising phrase is the tell -- 'as everywhere else' is what turns a
statement about our tooling into one about the disc.
Also records that a refutation is exactly as wide as the job a claim was offered
for: 37 of the 63 pairs differ without a button-count mismatch, where my reading is
unsupported rather than refuted, and they wrote the bound when the wider version
was available.

sylpheed-port refuted the untested reading I recorded yesterday with a count, and I
reproduced it: 26 of 65 adjacent GP_DIALOG pairs differ in BUTTON COUNT, which two
languages of one dialog cannot. The names agree once read rather than counted --
ranking_NEXT against ranking_JUMP, py_ranking against pzeff, pzstg10 against
pzstg02.
So adjacent entries are unrelated dialogs, the 63 never needed the language
reading, the 2 matching pairs need no special account, and the 140:70 ratio is a
counting coincidence -- the same fact my halves-pairing zero was showing from the
other side.
Preserving their caution: this does not establish that 0/1 and 2/3 ARE language
pairs. Identical element sets is equally consistent with a duplicate, and for the
37 pairs differing without a button-count mismatch the language reading is
unsupported rather than refuted.
Withdraws a delivered claim: I called entries 2/3 'an EN/JP pair' in HANDOFF. The
DIFFICULTY identification does not rest on it -- unique geometry plus the capture
does -- but it was stated as fact and was not one.

GP_DIALOG has exactly 140 entries against the table's 70 records, a 2:1 ratio that
would make the unbound join an ordering question. It does not hold: adjacent
pairing gives identical element-name sets on 2 of 65 pairs, halves pairing on 0.
GP_TITLE's language pairs share element sets exactly, so identical sets are the
signature there; in GP_DIALOG almost nothing matches.
Residual and unexplained: the only two adjacent pairs that DO match are entries 0/1
and 2/3, and 2/3 is the DIFFICULTY build.
A reading I am not asserting: dialog text may be baked into language-specific
sprites, which would explain the 63 by construction but leaves the 2 needing their
own explanation. Not tested.
The join stays unbound; positional ordering is now ruled out, which narrows where
to look next.

Chasing the reach I recorded this morning found the binding it said was missing.
Every DLG_ string in the image is pointed at by one aligned word at a 12-byte
stride: {u32 handler, u32 id, u32 name_ptr}, spanning 0x820A0A2C..0x820A0D68 with
three distinct handlers. Complete -- 70 names, 70 records, none unmatched -- and the
ids are banded and monotonic with a single gap at 24. Read from the image directly.
Refutation attempt on the shared reach, which both agents had recorded: 'another
four-button dialog with the same rows would be indistinguishable'. Scanned every
build in every pak for four buttons within 6 px of 259/329/399/469. Control found
both incumbents; zero rivals exist anywhere on the disc. So the geometric
identification is unique disc-wide, which is stronger than what either of us
claimed.
Still unbound: id 2000 to a pak entry. The tie remains uniqueness plus the oracle
capture, not a pointer.

Closes a negative of mine whose failed assumption I had named: I searched for an
8-record btn-named build in an archive of its own, assuming DIFFICULTY's four items
pair with f variants the way GP_TITLE's screens do. It has its own prefix and is
not a GamePart screen at all.
Three independent routes agree. The image lists DLG_SELECT_DIFFICULTY among the
DLG_* dialog names at 0x820A41BB, and GP_DIFFICULTY appears zero times. GP_DIALOG
entries 2/3 are the only builds there with pcbtn00..03 -- four buttons at design
rows 259/329/399/469, spacing 70, an EN/JP pair. And my capture of the running
screen puts its four rows within 4 px of those, with spacing 70.5/69.5/70.0 against
the disc's 70/70/70.
Reach stated: the entries are identified by button count and geometry, not by a
binding from the DLG_ name to a pak entry. No such binding was found.
Also notes the consequence for Q6's count-match: NEW GAME opens a DIALOG from an
external archive, which still matches the count but is not the same category as
OPTIONS or TUTORIAL opening a GamePart.

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.

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.

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.

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

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'.

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.

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.

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.

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.

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.

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

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.

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.

Its line 81 headed 'an individual SE's audio is not extractable yet' while line 189

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

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.

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.

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

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.

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.
