The run was launched to settle whether GP_DIALOG 2/3 are specifically EN and JP. It
did not reach DIFFICULTY: the reach probe's round trip failed at the final A, the
game sat off-menu at glyph 11654, and the sweep then timed out without pressing NEW
GAME.
Not a detector problem, which is what I assumed while watching. The JP menu detects
perfectly at glyph 320 against English's 327, both inside the 250..420 band; the
11654 is a later phase.
What it did establish: the locale took, and this is the first JP main-menu capture
in the corpus. JP initial focus is 新規 -- NEW GAME, top item, ring y 225.5, the same
item and row as six English boots. And the ring rows match English exactly, so the
JP build places its buttons where the English one does. That is language-pair
structure at the MENU, which is not the dialog pair the question is about.
Locale restored and verified at language = 1 by the trap, on a failing exit.

sylpheed-port found this in their own §6 and it is in mine identically. I stated the
pass condition as 'exit 0' but left the command silent, so a reader running it as
written sees an empty line and cannot tell success from failure. Worse than a number
without a pass condition, because there is no number.
Now carries '; echo $?' and says why.

sylpheed-port's standard, applied here: a documented command nobody has executed is
the same class as a control that does not execute. Mine did execute, but they were
published without expected outputs, and a command with no pass condition is half a
check -- a reader gets a number and no way to know whether it is the right one.
Each command now carries its pass condition, the placeholders are real shell
variables rather than <branch>, and the last run's results are recorded: 330, exit
0, 0, 1.

sylpheed-port re-derived this the same day and read 329 for my branch where I had
written 328, because a commit landed between the measurement and the check. The
counts rise with every commit on either branch, so they are not the claim.
What does not move with them: main is an ancestor of both, the change sets touch
zero files in common, and the dry-run merge is clean. The document now says that and
carries the commands to re-derive all of it.
A number that goes stale the moment it is written, sitting in a document meant to
inform a decision, is the same shape this week has been full of -- and this one was
mine, one message after recording the class.

PROTOCOL says a human merges, and both agents have been blocked behind that while
describing it rather than measuring it.
Decoder branch is 328 ahead of main and 0 behind; port branch 257 ahead and 0
behind. main is an ancestor of both, so each is individually a fast-forward.
And they do not conflict with each other: from their merge base the two change sets
touch ZERO files in common, and git merge-tree --write-tree of the two heads exits
clean with no conflict markers. Both can be merged in either order with zero
conflicts.
Nothing was merged. merge-tree is read-only and no branch was modified -- this is a
measurement, and merging remains the human's.

sylpheed-port turned my point -- that a static record still declares a cycle, so a
nonzero +0x08 against a largest time of 0 is a real disagreement -- into a check on
the screens they ship. Re-derived from my reader and it reproduces exactly: 65
nested records in GP_TITLE, 20 declaring a cycle with every pose at t == 0, and 0 of
those with any element carrying more than one pose.
A record whose elements each hold a single pose renders identically looped or held,
so holding them still is correct and now measured.
It includes ptbtn11/12/13, EXTRAS' buttons in both language entries, each declaring
120 units with one pose per element. Had any carried two poses, a menu button the
disc says animates would have been held still on the one submenu the port's P5 gate
walks.
Reach: GP_TITLE only; 1530 static records exist disc-wide against the 20 here.

Claude-Session: https://claude.ai/code/session_01Wuu56cE8vJGTBtn1ppsk8v
sylpheed-port corrected their own reconciliation and I reproduced it: 0 nested
records on this disc lack a timed keyframe. All 1530 are static -- timed, every pose
at t == 0 -- so the question is well-formed there and 'not exact' is a real answer,
not an absent one. A static record still declares a cycle length.
So the two percentages are two populations and neither corrects the other: 92.3 % of
animated records, 49.6 % of all nested records including static ones, same numerator
1643. Both need their population attached.
Two wrong explanations preceded this, both mine to carry: that my scan filtered
untimed records, which .max() returning Some(0) prevents, and then their 'questions
never asked' framing which I adopted.
The page is rewritten to the settled state rather than stacked. Nothing the port
depends on moved at any point.

Claude-Session: https://claude.ai/code/session_01Wuu56cE8vJGTBtn1ppsk8v
sylpheed-port reconciled the population gap exactly and I reproduced it: filtering
max_t > 0 gives 1781 records and 92.3 %, their figures precisely. Same numerator,
1643, both ways.
My stated explanation was wrong. I said the scan requires a timed keyframe; it does
not, because .max() returns Some(0) rather than None for records whose keyframes are
all at time 0, so 1530 records where the question has no content stayed in my
denominator and counted as failures by construction.
The conclusion is untouched -- +0x04 is 0 % under either denominator.
Records their diagnosis of why it stayed invisible: the numerator agreed to the
unit, so a shared 1643 read as agreement and neither of us looked there. And both
halves needed a qualifier neither carried -- 92.3 % is of the records where the
question is meaningful, not of nested records.

sylpheed-port aimed my own boundary finding at my loop-length control. Reproduced
from my reader over every pak: +0x04 has 0 violations too, so the falsifier rejects
+0x0c and accepts +0x04 and never discriminated. What identifies +0x08 is the
exactness statistic the page presents as secondary -- exact match in half the
records against 0 % for +0x04.
Population differs from theirs, 3311 records against 1781, because this scan takes
every pak and requires a timed keyframe, so the percentage moves but the
discrimination does not.
Second time this week with the weight on the wrong leg: a count taking credit for an
exclusion argument, now a falsifier taking credit for an exactness statistic, and
both times the real discriminator sat beside it described as a formality.
Their general form is sharper than my boundary rule: an interior consistency check
is satisfied by any internally consistent reading, and that is what a wrong offset
into a regular structure usually is.

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.

Their sharpened form is that well-argued prose never cited anything, the detail
being what made it look sourced. In this corpus cited sections have a median of 2502
characters and uncited 2386 -- indistinguishable, so care does not predict citation.
The predictor is recency: 79 % cited on 2026-08-29, 96 % on 08-30, 100 % on 08-31.
Caveat recorded: the improvement coincides with this exchange, so the norm becoming
salient is part of what produced it, and it is not evidence of a durable habit.
The distinction matters because the prognoses differ. Theirs is generative -- a
quality-correlated blind spot keeps producing instances. Mine is a legacy residue,
finite and closable by a backfill. Reading their diagnosis onto my corpus would have
implied work that is not needed and missed work that is.

sylpheed-port found an authored value whose why said 'ask the RE agent' without
naming where the question is recorded, and their rule transfers: without a citation,
an invented value and a placeholder for a measurement read identically.
Measured the analogue. Of 57 HANDOFF sections asserting measured, undecodable,
authored or ❔, nine cite nothing openable. Two are legend sections. One is a real
measurement -- 'B from EXTRAS DOES go black' -- delivered as an inline frame table
with no file cited, while data/fade-four-transitions.txt carried that leg and eight
others the whole time. Citation added.
Records their mechanism as the transferable part: a blind spot that correlates with
quality is invisible by construction. Their unlabelled entries were the

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.

sylpheed-port found a harness note asserting an unestablished fact under a
load-bearing number. Swept my printed output: 38 lines assert a screen or game fact
and the assertive ones are computed in the same run, so no instance there -- though
the sweep is keyword-based and the criterion is a judgement.
The class is real on the larger surface, and I have a known instance: ring_row.py
documented its calibration as 49.5 + 1.060*design_y, wrong because it was fitted
against menu_focus.py's approximate rows rather than the disc's. It sat in the file
underpinning every focus finding and was found by accident.
Tool docstrings carry calibrations, thresholds and claims about the game, nothing
verifies any of it, and unlike a why in an authored file there is no convention
demanding a citation.

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.

The finding stands -- my own page said the menu's bank was undecodable from the disc

check a row that had been struck for days, because I read my checkout's 2026-08-29

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.
