bcdd70123e re: correct the dialog record alignment, and close the static route to the id-entry join
Two things, both from reading the image.

The record layout is {id, name_ptr, handler}, not {handler, id, name_ptr} as first
published -- the same three fields shifted by one word, so every record was credited
with the previous record's handler. Caught by a control dump: under the old
alignment record 0 had a 'handler' of 0x10000000, not a code address. ids and names
are unaffected and DLG_SELECT_DIFFICULTY is still id 2000; only the attribution
moved. Corrected histogram over 70 records: 0x821D0808 x43, 0x821D05D8 x24,
0x821CFD80 x3.

And the id-to-pak-entry join is not reachable this way. All three handlers load the
same global at 0x828E2B14 and two take addresses at 0x828E45E0/4640/467C, and every
one of those sits inside a 364 601-byte contiguous zero run -- BSS, populated only
at runtime. Controlled: the dialog table itself reads non-zero through the same
arithmetic, so the addressing is right and the data is genuinely absent.

Reach stated: this closes one route, not the question. 'Not in the image' is not
established -- 'not reachable from the dialog handlers' is.

e4969c8cd9 re: attempted an instrument for stale justifications in tools -- it failed
sylpheed-port has found four retractions that never reached their source and I found
one. A register cannot catch the general class, since it holds only claims already
retracted. Tried to build something that does not need the retraction.

Attempt one, flagging tools whose cited page is newer, gave 126 candidates and no
signal -- pages are appended to constantly. Attempt two, narrowing to pages that
later received a commit whose subject marks a correction, gave 43. Sampled three
and all three are false positives: each tool cites its page for one fact while the
correction concerns another.

The proxy fails structurally -- co-citation is not co-reference -- so it is not
published. Reach: 3 of 43 sampled, rate not established, only shown low enough that
the report is not worth reading.

What found all five real instances was a person reading a sentence for its own sake.

a111f28b63 re: GP_DIALOG 0/1 is a byte-identical duplicate; 2/3 is a structural pair
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.

5b2713cac0 re: withdraw the sprite-count leg -- it does not reproduce, and the conclusion never needed it
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.

1be495167e re: the 37 are refuted too -- adjacent GP_DIALOG entries carry different STAGES
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.

2df5b04768 re: my language-sprite reading is refuted, and 'EN/JP pair' is withdrawn from the DIFFICULTY row
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.

843f27b506 re: the dialog id to pak-entry join is not positional -- hypothesis refuted
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.

5010b677c0 re: decode the dialog table -- 70/70 records, DLG_SELECT_DIFFICULTY is id 2000
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.

ba8202b457 re: DIFFICULTY is a dialog -- DLG_SELECT_DIFFICULTY, GP_DIALOG entries 2/3
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.

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.

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'.

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.

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.

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.

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.

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.

a5d49acd29 re: the frame-vs-audio clock run is void -- four instrument faults, control caught it
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.

80ef6ac4e2 re: the container's audio clock is within 1.5 % of real time -- a uniform slowdown is refuted
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.

036d5ef0bb re: two sweeps, two instrument faults -- the three submenus are still unmeasured
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.

4ed75e6c59 re: EXTRAS resets to MISSION SELECT while the main menu persists -- no menu-wide rule
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.

76013733c6 re: refutation attempt on Q2's 'shipped twice' -- it survives, with one real caveat
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.

bf9e07f8c9 handoff: Q2 enumerated six of eight screens and mis-paired the splashes
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.

9b7a8b3237 re: the focus reader was two items out -- initial focus is NEW GAME, and my labels were wrong
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.

4d954a8d0a re: two boots failed because the title gate tests for stillness on a screen that never stills
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.

dcfb53bc9b re: a bank's wave 1 is not a filtered copy of wave 0 -- and my own discriminator cannot finish the job
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.

27ce59b3a7 re: the sweep IS drawn on the JP title -- and my gate was phase-locking the shutter
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.

885cc1f898 re: the absence half of the gate audit -- 3 flagged, 0 real, and the audit was narrower than its wording
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.

4e077fc235 re: audit MISSION's own gates, both halves -- clean, with the checks stated
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.

668255118d re: build the enforcement check REFUTED.md lacked -- 0 real revivals, and why
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".

f7f25b73db re: try to name the two unidentified destinations -- rejected by my own calibration
sylpheed-port's caveat on the ninth transition: the destination is identified
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.

596d21b882 re: a ninth transition -- the same origin gives gap 0 and 1 by destination
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.

ac1ee549f3 re: the gap is a property of the ORDERED PAIR -- and the guard verified in a run
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.

826599cab8 re: break the EXTRAS n=1 cap -- which I had wrongly called structural
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.

0e81cfacc9 re: a third menu-outgoing gap, and leaving the archive costs no extra black
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.

a9b6e78c8f re: the black gap tracks the OUTGOING screen -- direction and button ruled out
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.

3e525756bf re: a third title->menu replicate, from a run that ran the wrong experiment
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.

dc36c85f85 re: the inverse sweep -- 41 env vars read, 22 undocumented, none in the UI path
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.

0979ae9063 re: finish the --help audit -- a stale percentage and a missing noun, both shipped
The METHOD entry I wrote an hour ago says to read your tool's own --help as if a
stranger wrote it. I had done that for ONE of sixteen leaf commands, which is the
"a rule written down is not a rule applied" failure this corpus already records
twice. Finished it across the whole surface.

One survivor, and it fails in two ways at once. `screen render --settle` said a
narrow window means the bundle never settles, "(42 % of them, mostly loop*
fragments)".

MISSING NOUN: inside `screen render`, "them" reads as the builds you would render.
The 42 % is over composable bundles -- a different and much larger set including
~1 700 two-element fragments a user of that flag never renders. ui-settle-time.md
states its population precisely; the help inherited the number without it.

STALE: recomputed under the corrected reader, the composable figure is 862/2211 =
39 %, not 731/1758 = 42 %. The POPULATION GREW BY 453, which is the keyframe
record-layout fix's signature -- it times a group's final pose, so bundles that
previously showed one timed keyframe now show two and qualify. Third consequence
of that fix not being swept, after fade_quads.py and screen-transitions.md's
0.87-4.08 s fade-in.

And the share a --settle user actually faces is 38 %: 185 of 491 screen builds.

Corrected in the help text with all three numbers and their populations, and in
ui-settle-time.md, whose three-row table is marked pre-fix and superseded rather
than edited in place. Verified by artifact -- the tool's --help output is quoted,
not merely recompiled.

eb4a5c8507 re: test the port's black-backdrop predicate disc-wide -- exact locally, rare globally
sylpheed-port proposed that a screen declaring a full-screen .prm at t=0 with
fade == 0xff000000 is standalone, and one without it is composited: 12/4 across
their sixteen exported screens, every exception independently known to be
composited. They asked for it against archives they do not have. That is my lane.

CONTROL: the predicate reproduces their split exactly. GP_TITLE's sixteen bundles
give 12 with and 4 without, the four without being entries 0, 1, 2, 3 --
build_00, build_01, press_start, press_start_jp -- and the element names match
(pteff00.prm, palogo_eff0.prm, pgloading_eff00.prm). Independent derivation from
the disc, not a re-run of their tool.

DISC-WIDE it is rare: 76 of 965 screen builds, 7.9 %. GP_STAGE_CLEAR 4/4,
GP_SYSTEM 2/2 and GP_TUTORIAL 2/2 are all-yes; GP_HANGAR_ARSENAL is 0 of 390, and
GP_READY_ROOM, GP_OPTIONS, GP_PAUSE_MENU and GP_GAMEOVER are all zero.

So it is not a general standalone/composited test. GP_OPTIONS and GP_PAUSE_MENU
are screens a player plainly sees as screens and declare no backdrop; read as
"composited" the rule would make 92 % of the game's screens composited, which the
archives do not support. What it appears to separate is narrower: screens that
BEGIN FROM BLACK from everything else. A pause menu over gameplay, a hangar over a
3D scene and a plate over a title all lack a backdrop without being the same kind
of thing -- the negative class is heterogeneous, which is what a two-way rule
cannot express.

For the port: exact within GP_TITLE, so --black for those twelve is justified from
the file rather than assumed; do not carry it into the four archives they have yet
to export, where in three of them it classifies every screen alike.

348e5d8281 re: the leaf's clock is undecodable with reach -- and the rotation is confirmed
Four models for how the game advances the sweep leaf, four refutations.

Frame-locked predicts px/frame unchanged under --framerate_limit; measured
-4.348 -> -2.032. Wall-clock predicts px/frame LARGER at a lower limit; it got
smaller. sylpheed-port's alternative -- that my samples might be at a fixed
wall-clock rate while guest time slows, which would reproduce the direction --
checked rather than assumed: every capture reports 150 frames spanning 1..149, so
the capture is indexed by guest VdSwap submissions. And per UI-drawing frame,
which matters because at limit 15 only 99 of 150 frames carry draws against 131
at default, gives -5.773 vs -3.687, ratio 1.57, not invariant either.

Three measures of one slowdown -- 3.58x on the boot, 2.14x per submitted frame,
1.57x per appearance -- and no two agree. The clock is none of the four and the
absolute rate stays unpinned. Recorded as undecodable with the reach stated.

Two things the same data does establish.

The rotation is confirmed FROM THE ORACLE. The port's export carries rotation_deg
+30 on pteff03 and -45 on pteff03a, read from the file. The AABB height of a
rotated quad predicts from the declared scale alone: 400x1080 at +30deg -> 1135.3
against 1134 observed (0.12 %), and 400x1440 at -45deg -> 1301.1 against 1303
(0.15 %). Two angles, two scales, both under 0.2 %.

Which makes their inversion real. Height 1134 IS pteff03 -- the leaf whose
declared track is perfectly linear at +4.0000 px/unit across both segments -- and
that is the strip my sign-change gate FAILS. Height 1303 is pteff03a, the
slightly non-uniform one, and it passes. The curvature is in the strip whose
source is exactly straight, so it is not in the disc: it is in the measurement or
in how the game advances the record.

721de02723 re: the leaf is NOT frame-locked -- and a residual gate disqualifies half my fits
The frame-rate test sylpheed-port and I agreed was the only clean route left.
Same strips, same screen, --framerate_limit=15 against the default. The limit
demonstrably took effect: the title settled at 862 s against 241 s.

First, a gate this work should have had from the start. A slope is only a rate if
its residual is random, so count sign changes in the residual:

  default   1299x1303  -4.348  rms 3.33  43/111  OK
             883x1134  +4.284  rms 3.08  21/76   SYSTEMATIC
             890x1134  +4.284  rms 3.19  15/54   SYSTEMATIC
  limit 15  1299x1303  -2.032  rms 1.51  44/83   OK
             883x1134  +2.003  rms 1.12  36/61   OK
             890x1134  +1.999  rms 0.74  12/37   SYSTEMATIC

So one of the two strips I quoted as "agreeing to three significant figures"
FAILS the linearity gate at default fps: that agreement was between a rate and a
slope through a curve. The port had already caveated the claim for a different
reason; this weakens it further from my own side.

The result, on the one group passing the gate at both settings: -4.348 px/frame
at default against -2.032 at limit 15, a ratio of 2.14.

THE LEAF IS NOT FRAME-LOCKED. A fixed number of units per submitted frame
predicts px/frame unchanged; it changed by 2.14x. Dead.

A simple wall-clock model is dead too, in the other direction: fewer frames per
second means more wall time per frame, so a time-driven leaf should move MORE
px/frame at a lower limit. It moved LESS. Neither model fits and I have no third.

Reach: the effective frame rate was NOT measured. The timing instrument I added
polls for the capture log, which is created when the capture is ARMED rather than
when it finishes, so it reported 0.728 s and is void. The 3.6x boot slowdown says
the limit took effect, not that fps went 28 -> 15. The RATIO is measured; the
absolute rate still is not.

f845dda9a5 re: three routes to remove the fps caveat, all closed -- 1.07 stands on one capture
sylpheed-port's caveat on my 1.07 units/frame: two strips agreeing to three
significant figures constrains the strips to each other, not the absolute rate,
because both ratios come from one capture under one fps assumption. They are
right and I could not remove it. Recording the three attempts and why each fails,
since a closed route is worth as much as an open one.

Route 1, compare the leaf to a TOP-LEVEL clock in the same capture so fps cancels:
not available. On a settled title nothing top-level moves -- that is what settled
means -- and every varying quad in the capture is a leaf. The plate looked like a
candidate (538x76, clean ~56-frame pulse) but build 2's ptbtn00 is a one-shot fade
at t=0,214,236,238,244; the repeating pulse comes from its own nested .rat.

Route 2, fit the same strips in the transition captures, which DO carry a
top-level clock (the fade quad, 8 declared units at 2.0 units/frame). The strips
are present but the fits are not measurements: rms residuals of 26.70 and 16.75 px
against 147 px of travel, versus 3.59 px against 627 px in titledraw2. Scatter,
not a line. The apparent disagreement between captures is a NON-measurement, and
quoting 1.94 or 3.57 as a second sample would have repeated the 6-7 px/frame
eyeball error one message after withdrawing it.

Route 3, read fps from the emulator's own log: not printed.

So 1.07 rules out a per-record quirk and does not pin the absolute rate. The test
that would is measuring the same strips at a deliberately different emulator frame
rate -- unchanged px/frame means frame-locked, scaling with 1/fps means wall time.
Not run.

5baf88eba0 re: withdraw "the sweep rate matches the disc" -- two errors that cancelled
sylpheed-port corrected the disc figure I compared against: the leaf's final
segment HOLDS, so a cycle length is not a motion duration. Verified from the
disc rather than accepted -- pteff03 moves over t=0..540 of a 600-unit cycle
(4.000 px/unit, not 3.600) and pteff03a over 0..630 of 720 (4.063, not 3.556).

Checking that sent me back to my own measurement, which was worse. "6-7
px/frame" came from eyeballing deltas between consecutive APPEARANCES in a
capture that skips frames, so a delta of 7 often spans two frames. A
least-squares fit of x against frame over all 132/112 points gives +4.287 and
-4.348 px/frame, with rms residuals of 3.6 and 3.3 px.

So the confirmation I reported was a prediction 20 % too low meeting a
measurement 50 % too high. Neither number was right and the agreement was an
artefact of both being wrong -- which is the most dangerous form of agreement in
this corpus, because nothing about it looked suspicious.

The corrected numbers say something larger than the claim they replace. Measured
against declared: 4.287/4.000 = 1.072 units per frame, and 4.348/4.063 = 1.070.
Two independent strips with different cycle lengths and different declared rates
agree to three significant figures. Q1 establishes 2 units per RENDERED frame for
top-level elements. So either a nested leaf record advances at about half the
top-level rate, or Q1's factor does not apply to nested records. Measured, not
explained, and flagged as deserving its own iteration because Q1 is load-bearing.

One untested candidate recorded: 1 unit per 1/30 s of game time against the
~28.5 fps this corpus measures for the idle title gives 1.053, close to 1.07.

7fd958f50e re: the game DOES draw the sweep leaves at rest -- my own hypothesis refuted
Last iteration I hypothesised that the game might not draw pteff03/pteff03a on a
settled title, which would have explained three things at once: the flat --at
plateau, the 0.32 between-session in-box term, and part of the ~40 residual. The
oracle says no.

A draw capture of the settled EN title -- gated on the plate pulse, fired at
325.3 s, with exactly ONE emulator verified by count -- shows two quads taller
than the 720 px screen present in every one of 132 frames and sweeping in
OPPOSITE directions:

  strip A  h=1134  ROT  x -109 -> +518   step +6..7 px/frame
  strip B  h=1303  ROT  x +486 -> -154   step -6..7 px/frame

The rate matches the disc: the declared x track is -639..1521 = 2160 px over a
600-unit cycle = 3.6 px/unit, and at 2 units per rendered frame that predicts 7.2
px/frame against 6-7 measured. Both quads are flagged ROT, which is why their
axis-aligned bounding boxes are ~885 and ~1300 px wide where the declared quad is
400 -- consistent with rotation living in leaf records and with `screen render`
being axis-aligned only.

So the leaves ARE drawn and DO free-run on a settled title. My hypothesis is
refuted and sylpheed-port's reading of their `title` curve -- sweep present in a
title capture -- is confirmed by the oracle rather than by a render.

What this does NOT settle is the tension that prompted it. Both strips cross the
adjudication box in x and cover it in y, so two JP captures at different phases
should differ there, and they differ by 0.32. Two candidates, neither tested: the
two JP shutters happened to fall at similar phases (a ~1 % coincidence for a
600-unit cycle), or build 7's denser logo stack -- the katakana plus the
crystalline burst that jp-title-at-rest.txt records as absent from the English
title -- occludes the sweep inside that box. A draw capture of the JP title
distinguishes them.
