menu_blend_capture.sh counted two DOWNs to reach EXTRAS, which is wrong twice
over -- EXTRAS is the fifth item, and on 2026-08-31 four DOWNs landed on OPTIONS
because one press was dropped. It now presses until the cursor stops moving,
which needs no item count and no row calibration. Its title deadline follows the
same change as title_blend_capture.sh, 1200 s not 420.
ui_blend_map.py takes a comma-separated build list, because the live title is
TWO builds composited -- 4 draws the art, 2 draws the PRESS (A) plate -- and a
one-build size table cannot name the elements of a title capture.
frame_alpha_census takes its builds from argv for the same reason.

I wrote that yesterday in HANDOFF, the finding page and INDEX. It is false: in
one main-menu frame, draws 5, 6 and 7 are three separate additive draws --
consecutive, identical blend state, not merged.
Only the one-way implication holds: elements inside one draw share a blend
state; sharing a state does not put elements in one draw. The wrong version
would have licensed the port inferring a mode for an element nobody observed,
which is the one thing that page must not do. The ptframe4 conclusion is
unaffected -- it is in the same DRAW as ptframe3, not merely the same mode.

The declaration entry's kind word (+0x28) and its focus/nav index (+0x2C) are the
same fact twice: kind & 0x2 is set iff the focus index is >= 0. Checked over 24
UI paks and every parseable build in each -- 1062 focusable elements, 14431 not,
zero exceptions. The test is two-sided, so it would fail if any focusable element
lacked the bit or any non-focusable element carried it.
Consequence: kind == 0x3002 is not the test for a button. It catches 778 of 1062
and misses 284 (26.7 %) at 0x2, 0x2002, 0x3003, 0x73002, 0x73003 -- including
ptbtn00.rat on GP_TITLE's PRESS (A) plate, which is 0x73002. And 0x3000, 817
elements, looks like a button and is not focusable.
This is also the refutation attempt on sylpheed-port's kind census. Their claim
-- every decoration 0x0, every button 0x3002 -- is exactly right on the two
screens they checked, reproduced here independently, and fails one build over on
the title they have not run yet.
The other kind bits are reported as observed structure and explicitly not
claimed.

Completes the reach of ui-blend-mode-measured.md, which was explicitly two
screens and one session and explicitly not the title.
Three things it does differently from menu_blend_capture.sh, each one paid for
yesterday: a 1200 s title deadline instead of 420 (the 420 fired while the game
was minutes from the settled title); the title arm is gated on the plate pulse
because build 2's PRESS (A) plate is part of what is being measured; and on
timeout it leaves the emulator up and says to attach rather than reboot.
Committed before it is run, per METHOD.md.

0x8050 dies disc-wide (38 sprites, high byte tracks the archive) and again on
EXTRAS, where pteff21/22/23 share it with the frames.
The port's 'neither frame has a fully-opaque pixel' is true and is not the
discriminator: pteff10 has max alpha 130, no opaque pixel, and they measure it as
nearly exact. Their direction survives -- the draw path did answer -- so what is
refuted is the reason, not the conclusion.

Two traps this run paid for.
ring_row.py's ROW0/SPACING are x11grab constants. On a /sylph-home/re/shots/shot-0001.png grab of the
same live main menu the rows read 180.5/419.5/502.0 -- ROW0 is 45 px out, 0.57
of a step. The module refused rather than naming the wrong item, which is the
good failure, and is_main_menu() therefore returned False ON A REAL MAIN MENU. A
run gated on it would conclude 'not the menu' while sitting on the menu. Not
recalibrated: three rows from one session are not a calibration and other tools
share the constants; the module now says so where the numbers are.
menu_draw_capture.sh's 420 s title deadline fired, and the emulator left running
was at the settled title minutes later, took one A, and reached the menu first
try. A timeout is a measurement of the timeout. Leaving the emulator up after a
failed script rescued this run for one minute against a twenty-minute reboot.

HANDOFF gets the measured table, the two controls, the three caveats that travel
with it (src=ONE is not evidence of premultiplied textures; the frames share a
draw call so ptframe4 comes free; read it as per-element facts because the
selecting field is still unknown), and the correction to the port's own
sharpener -- 'neither frame has a fully-opaque pixel' is true and is not the
discriminator, because pteff10 has none either and renders accurately.
t32-blend-mode-not-on-disc.md keeps its negative and its reach and loses its
conclusion. INDEX gets the row.

Closes the one route t32-blend-mode-not-on-disc.md left open: the executable's
draw path. Canary's UI draw capture now logs RB_BLENDCONTROL0 per draw, and the
game was driven to the main menu and to EXTRAS with F10 at each.
The title-side UI uses two blend states and ONE pixel shader:
0x07010701 src=ONE dst=1-SRC_ALPHA alpha-over (premultiplied)
ptbase, pteff05, the fade quad, ptmsg, ptmsg2, pttitle, buttons
0x01010101 src=ONE dst=ONE ADDITIVE
ptframe1, ptframe2, ptframe3, pteff20, both rotated sweep strips
Two controls, both run before the result was read:
* the NDC->pixel conversion that identifies a draw by its quad size reproduces
1134 and 1303 px for the two rotated sweep strips -- numbers measured by a
different tool in a different session -- on BOTH screens. The tool prints
PASS/FAIL and disclaims its own output on FAIL.
* pixel shader 0xE59B2B3DA4AA9008 is used with BOTH states, 12 draws additive
and 18 alpha-over. ptframe1 and ptbase run the same shader; only the blend
register differs. So this is a blend result, not a shader result.
This confirms the port's independent measurement -- it solved the composite per
pixel from two backgrounds and found additive halves alpha-over's error on both
frames -- by a route with nothing in common with it.
So the blend is no longer authored: 'any blend you choose is authored' was true
of the disc and is not true of the game. What is still unknown is which field
selects it; elements sharing a mode are batched into one draw call, so the
selection happens before the draw.

Identifies each draw by the pixel size of its quad -- NDC extents times the
1280x720 surface -- matched against sprite dimensions read off the disc, since
the log names no elements.
Carries its own control: build 5 draws two rotated sweep strips whose heights
were measured independently at 1134 and 1303 px in
docs/re/data/title-sweep-drawn-at-rest.txt. If the conversion does not reproduce
those, every size it prints is wrong and it says so.

CONTAINER-NOTES said a Canary source change costs a full reconfigure against
/canary and a full compile, and told the reader to budget a session for it. It
was right about the defect -- the warm build tree at /sylph-home/re/canary-build
is configured with CMAKE_HOME_DIRECTORY=/work/xenia-canary, which does not exist
here -- and wrong about the consequence.
Symlinking /work/xenia-canary -> /canary restores the path the tree was
configured with. A one-file edit to command_processor.cc then rebuilt and
relinked xenia_canary in under 10 minutes at -j4, exit 0, no reconfigure and no
OOM. This is how the blend-state logging in the same session got built.
The symlink is untracked inside the repository, so the note also says to remove
it afterwards.

Canary's CaptureUiDrawForRE now logs RB_BLENDCONTROL0, RB_COLORCONTROL and
RB_COLOR_MASK per draw, raw and decoded, alongside the shader hashes and bound
texture it already logged. This script drives the game to the main menu and arms
it there.
Unlike menu_draw_capture.sh it does NOT pass --log_ui_draws: Canary's own source

The port measures four elements as rendering too dark against the capture --
ptframe1/2 on the main menu, ptframe3/4 on EXTRAS -- with the shortfall
correlating +0.77/+0.80 with the BACKGROUND and only +0.24 with the element's
own contribution. That is the signature of a blend that scales what is already
there. It asked whether the disc selects one.
Three examples, one negative, wider than the one I gave last iteration:
* frame_alpha_census -- every T8aD sprite on builds 5 and 6 by alpha. It
REFUTES the port's own sharpener: 'neither frame has a single fully-opaque
pixel, against ptbase's 99.1 %' is true, and pteff10 (max alpha 130, 100 %
partial, no opaque pixel) is measured by the port as NEARLY EXACT. So being
wholly semi-transparent is not what makes the frames special.
* frame_vs_accurate_words -- all 12 T8aD header words for both screens, plus a
per-BIT sweep of +0x04 and +0x08. NO word and NO bit puts the four frames on
one side and pteff10 on the other. It also kills my own remaining candidate a
second time: +0x08 = 0x8050 is shared with pteff21/22/23 on EXTRAS.
* frame_keyframe_unknowns -- the keyframe record's fade, tint, rotation and its
two unexplained signed words. unknown_4 and unknown_8 are ZERO on every
keyframe of both screens, so they carry nothing here; no frame takes a value
of any field that another element does not.
Reach: the 60-byte declaration entry, the T8aD header word-wise and bit-wise,
and the keyframe record. Four elements, two screens. Not the executable's draw
path, which is the next commit.

Answers the port's ask about ptframe1/ptframe2, whose residual is uniquely higher on
flat pixels than edges and signed one direction -- a body-intensity difference.
Prior work covers .prm primitives and a refuted T8aD +0x04 bit; neither covers a
.t32 element. All 15 words of the 60-byte declaration entry are read: 3 are the
name, 8 constant, the rest kind, focus index, position and pivot. The frames are
kind 0, identical to every other plain sprite.
One candidate found and refuted by myself: T8aD +0x08 is the only word where both
frames agree uniquely on that screen, at 0x8050 -- but 38 sprites carry it
disc-wide, only 8 named frame, and the high byte tracks the archive. It is an
atlas/format word, not a mode.
Also records a false positive of my own test: +0x00 and +0x08 first read as
'separating the frames' because those words are the name string.
So any blend the port picks is authored. Reach: not looked at the executable's draw
path, where a mode selected in code rather than data would live.

sylpheed-port mapped the menu's edge residual at 64 px tiles and handed over
coordinates without names, which is the division I proposed: the map is theirs, the
element inventory is mine.
Under the hot band at x 384..704, y 64..256 sit ptframe1.t32, ptbtn01.rat (the NEW
GAME button) and pteff12.t32, an effect element -- all three hot under BOTH
coordinate readings, so the answer does not depend on whether their tiles are in
design or capture space. ptbtn02 is hot in design space only.
So the hot region is not one element but three of different kinds overlapping, which
is consistent with their null: they looked for two families of tile and found one
continuous population, so the region has no character of its own.
This names what is there, not what is wrong -- their map already excludes local
displacement in these tiles. Also records their control limit: a +2 px displacement
reads back +0.839 because the slope saturates, so any slope they report is a floor
on the displacement and never a ceiling.

sylpheed-port ran the signed-edge discriminator I proposed but could not execute --
it needs their render beside the capture. Recorded as their measurement, with their
tool and commit.
Controls against deliberately damaged copies of their own render: a known +1 px
shift reads back as +0.938 px, a known blur as r -0.896 on the laplacian, neither
leaking into the other's channel. The menu against the capture gives -0.010 px
horizontal, -0.009 px vertical, laplacian r +0.103 -- and the weak blur term is the
opposite sign to the blur control.
So global misregistration and blur are both excluded, and of the three candidates I
named the misplaced soft element is the only one left.
Reach is the whole reach: a whole-frame fit excludes a global translation, not a
local one, since one misplaced element is a small share of 38752 edge pixels. The
next test is local and needs the residual map, which is theirs.

sylpheed-port found that my control's premise misreads their figure. The 0.06 %
counts pixels surviving -threshold 25%, differing by more than ~64 levels -- a
gross-displacement detector, blind to sub-pixel offsets and antialiasing, which are
exactly what a per-level LUT also cannot close. It says no gross displacement, not
geometry is right, and I read one as the other.
Their direct measurement, attributed and not reproduced here: after the LUT the
menu's residual is 6.94 on edge pixels against 2.20 on flat, with a known negative
leaving 0.00. So the menu carries spatial error and is not a geometry-free control.
The 32/68 result does not rest on it -- 'whatever a fitted per-level LUT cannot
close is not a per-level effect' is the method's own basis and is self-standing.
What the control shows is narrower than claimed.

The ja capture of DIFFICULTY is taken. EN and JP differ in 1.82 % of pixels, in four
bands and nowhere else: the heading (DIFFICULTY -> 難易度選択), a 2 px ring shift, the
BACK label (-> 戻る) and the footer. EASY/NORMAL/HARD do not appear in the differing
set -- the Japanese release leaves the three difficulty names in Latin script.
So 2/3 are a language pair, and the disc agrees quantitatively: 2.77 % of bytes
differ against 1.82 % of pixels on screen. This closes the item left open when I
withdrew 'an EN/JP pair' as a bare assertion, and it is now measured rather than
inferred from the disc's convention.
The JP screen also opens on NORMAL like the English one, and the sweep reproduced
the reset finding in Japanese.
Reach: one JP boot, one screen. It does not generalise -- GP_TITLE 4/7 is already
known to differ by more than text.

menu, B to title, A back -- did not return, leaving the game off-menu, and the
sweep that followed timed out with nothing to work with. Arriving at the menu is

sylpheed-port checked the JP layout from their export: the disc declares identical
button rows for EN and JP on main_menu and extras. Recorded separately rather than
merged with mine, because they are different quantities -- their rows are declared
rest positions, my 225.5 is a runtime ring row on a surface offset ~65 px from
design space. Either could have disagreed, which is what makes them independent
legs, after a week of finding legs that were not.
Neither is evidence for GP_DIALOG 2/3; both are about GP_TITLE.
Also records the mid-run substitution: I diagnosed a detector failure from a log
line showing glyph 11654 when the capture was one read away and showed the detector
working. A log line is a summary someone wrote, and reading it as the observation is
the same substitution as trusting a harness note.

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.

The byte comparison showed 2/3 differ in 2.77 % while sharing every element name --
what a language pair looks like -- but that they are ENGLISH and JAPANESE rested on
the disc's convention rather than on this screen. This captures it in ja.
Reuses submenu_focus_sweep.py with SWEEP_TARGETS=0 rather than a new probe, so the
JP capture is taken by the same navigation that produced the English one. The locale
is restored on ANY exit including a crash, and the probe never presses A inside a

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

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.

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.

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.

sylpheed-port named a gap in their own rule: the fourth aside of mine to reach their
authored data was a STRUCTURE, not a decoration, and 'the unchecked things carry no
weight' did not cover it because a wrong field order looks like a fact. It carried
no weight only by luck. The fix belongs at my end, so this is the control that
should have existed when I published the layout.
The obvious form fails, and its failure is the useful part: checking that all
records are type-plausible passes on the SHIFTED alignments too, 69 of 70 in both
directions. A homogeneous repeated table has the same field types in sequence, so
any window starting on a field boundary type-checks and the interior carries no
information about phase.
Only the BOUNDARIES do. A shifted reading must consume a word from outside the table
at one end, and that word does not obey the field's type -- which is exactly how the
original error surfaced, record 0's handler reading as 0x10000000. Two-sided: the
published alignment survives at both edges and both shifts fail.

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
well-evidenced ones, because both audits measure self-declaration rather than
grounding.

sylpheed-port found audit-kinds auditing 16 of 71 authored justifications and never
saying so -- a checker that fails correctly while describing a sixth of the corpus.
Their line is the one that generalises: 'I checked and it was fine' and 'I checked
the part that declared itself' read identically in a log, and only one of them is
what gets quoted.
Measured here: of 86 refutation-shaped bullets in REFUTED.md, 83 are in the
registered form. 97 %, which is better than their 16/71 but was equally unstated.
The three gaps are deliberate, not a bug. They quote their claim in backticks and
are bare identifiers -- +0x29d0, position = instance - 0x12c -- so registering them
would match every live mention of the same offset and train the check to be
ignored. Reported rather than forced to 100 %, for the same reason they report the
ratio instead of demanding it: forcing a counter invites mislabelling, which is
worse than the gap.
Selftest and the real run both still exit 0.

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.

sylpheed-port found three live stale claims in their own source, each already
retracted in their log days earlier. Their framing is the one that matters: a
correction that does not reach the artifact a consumer reads has not been made, and
a comment sits beside the thing it describes.
check_refuted.py scanned docs/ only. Running it over tools/ and crates/ for the
first time found one here too: jp_title_session.sh justified its own existence with
'a free-running clock lands somewhere else on a fresh boot' -- a claim I refuted
myself the day before, when I measured the plate-pulse gate phase-locking the
shutter to 1.6 % of the sweep traverse. The script's stated rationale rested on a
premise I had already killed.
Fixed the file with the correction in place, including what it means for what that
script actually measures: a second capture through the same gate is a second sample
at nearly the same animation phase, so its RMSE 0.32 is a phase-locked lower bound.
Taught the register to scan code behind --code, excluding crates/sylpheed-viewer,
which is the human's tool. Controlled three ways: a planted code revival exits 1
with --code, exits 0 without it -- which is the proof the gap was real -- and 0
again once removed.

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.
