input-pad-read-path.md says of the word the C_PAD_DECODER reads: "There is
no shift and no remap on the way in -- the bit positions are XINPUT's own."
That is wrong. sub_8220D500 rebuilds the word out of XINPUT_GAMEPAD before
anything else sees it, into the game's own numbering.
bits 0-3 A B X Y
bits 4-7 left stick UP DOWN LEFT RIGHT (+/-20000 of 32767)
bits 8-11 right stick UP DOWN LEFT RIGHT
bits 12-15 D-pad UP DOWN LEFT RIGHT
bits 16-17 START, BACK
bits 18-19 LB, RB
bits 20-21 LT, RT -- digital, threshold >220 of 255
bits 22-23 L3, R3
Extracted mechanically from the image, no row typed by hand. The control is
the shape of the result: the 24 assignments land on bits 0..23, each used
exactly once, none repeated. A misdecode does not produce a bijection over a
contiguous range, and coincidence does not put the stick and D-pad
directions in the same order in two aligned nibbles.
So every mask in that page's tables names the wrong button. The 0xE000 x18
site, read there as "B | X | Y", is "D-pad DOWN | LEFT | RIGHT" -- eighteen
sites testing a menu cursor, which is what 18 sites should be.
And its headline negative is REFUTED: "LB and RB are not menu inputs" is
false. They are bound at config fields this+0x70 and this+0x84, LT/RT at
+0x74/+0x80. The negative was searched for 0x0100/0x0200 -- LB and RB in
XINPUT's numbering -- in a word where they live at 0x40000/0x80000. Right
function, right buttons, wrong bit positions, so it could only come back
empty. A negative is only as good as the numbering it was searched in.
Also decodes the ring record: +12 HELD, +16 PRESSED, +20 RELEASED, +28/+32
raw trigger bytes. Edge and level are one struct four bytes apart, which
displaces that page's guess that press-vs-hold was split between GetState
and the XamInputGetKeystrokeEx queue.
The superset claim in that page survives and is untouched: sub_82457038
really does compare every XINPUT_GAMEPAD field, and it really is
XINPUT-layout. This page depends on it.
Not decoded: which output bit means which ACTION, and per-screen sets. 5 of
18 output-bit sites did not resolve to a pad guard, so the output map is a
lower bound -- in particular "START is not tested" is NOT claimed.

Play-test finding 4, answered as a mechanism and from the disc, so it
generalises instead of describing one boot.
ui-splash-draw-pass.md excluded a post-process from GPU state and closed
with "that softness is in the texture or in which quads are drawn, not in
a pass", leaving the two unseparated. It is both, and they are one fact:
each logo ships a second texture that IS the blur -- the same artwork
outset by exactly 10 px per side, concentric to <=1.5 px, drawn as its
own alpha-over quad.
Three results, each with its control:
* The capture's eight anonymous quads are NAMED from the disc. Predicting
each NDC rect from declared position + decoded sprite size matches all
eight bijectively; every match <=0.0061, every runner-up >=0.0272, a
4.5-8.9x margin. That margin is the control -- eight similar boxes
would match anything.
* REFUTES splash-quad-timeline.txt's "the same three rects scaled
slightly larger" (my own earlier wording). The x and y scale factors
differ by up to 0.28; a uniform scale cannot do that, a fixed 10-px
border can. The conclusion it supported (draw all six quads) stands;
the model was wrong, and the wrong model tells a port to scale a
sprite.
* The T8aD blend bit tested OUT of sample on entries 10/11, which were
not in its 35-row fit and are the screens under complaint.
Pre-registered additive=false for all eight against 0 additive draws in
1048; held 8/8, with the control still reporting 9 additive on entry 6.
Also resolves a REFUTED.md 🟡 <our-reader> in the reader's favour: the
prediction is ours and the target is the oracle, so the agreement is
evidence about the reader rather than a claim resting on it.

Told the port plainly: their arithmetic was right, the 35-40 is withdrawn,
keep 60 for every screen, and do not average or split anything. Struck the
previous section's heading in place rather than deleting it.
Carried the instrument lesson across, because it is worth more than the
number: the guest timebase does not remove the pacing artefact, since the
game's animation clock is frame-coupled rather than being the guest
timebase. My control verified capability -- does this clock track real time
-- when the question was configuration: is the quantity I divide by coupled
to the frame rate.
Also told them what this leaves: both halves of the human's finding 4 that
were mine are answered and neither points at their export, so their own
unbound-A observation is now the strongest candidate and it is theirs.
Three sections, the correction first.
The rate is per-GamePart: title ~57, splash ~35-40. I gave them 56.8 an hour
ago and said the reach was the title; the splashes now have their own number
with T read off the disc. The hold is what makes it safe to hand over -- 160
declared units in 4.514 guest seconds, with no T, no alpha slope and no
interpolation in the arithmetic, agreeing with the same screen's ramp which
shares none of its algebra. Told them a splash played at 60 runs 1.5-1.7x
too fast, which is a TIMELINE cause for the complaint we had both filed
under blur. Classified measured, not decoded, and told them not to extend
either number to any other screen.
The R1-re-opened 'declared timeline reproduces the captured splash' settles
in favour of the timeline: 39/50 exact under truncation, worst error one
alpha level in 255, nothing off by more than one. So their export's splash
keyframes are right and the rate was the defect.
Refutation attempt on their H5, recorded whether it survived or not: it does
not. build_12 and build_15 have identical declaration bodies, so identical
statistics is one fact rather than two coincidences -- as do 0/1, 2/3 and
11/14, while 4/7, 5/8, 6/9 and 10/13 genuinely differ. Also recorded the trap
I hit first: the dump header carries the build number, so the compared text
contained the label distinguishing the subjects and every pair read as
different. A self-comparison control caught it.
Told them plainly: 56.8 is inside my pre-registered band, the control passes
at 1.15%, 30 and 120 are excluded, and my own earlier ~30 was a borrowed T
that does not apply to those elements.
Three instructions: keep 60 (5.6% away against ~5% resolution, not refuted);
units = 2 x frames stays dead because only the constant survives and not the
route; and the unit constant is now ELIMINATED as the cause of a late plate,
since at 56.8 the plate lands at 4.15 s against their 3.93 s -- they are
fractionally early. That closes H3's last candidate from their side.
Two sections, the retraction first.
The clock is time-integrated, not frame-counted, so 'units = 2 x frames' --
which I sent them two hours ago -- computes an emulator artefact. Told them
what still stands from that message (the T-vs-step arithmetic and the t~160
anchor, both ratios inside one run) and what does not.
Also told them explicitly to KEEP 60 units/s and act on nothing today: my
own measured 29.9 rests on a T whose usual derivation is circular with the
thing just retired, and a failed prediction is not a licence to move their
constant.
Their H4, the blend space: the game blends in the ENCODED space.
RB_COLOR_INFO.color_format is k_8_8_8_8 on 2402/2402 splash draws and
33779/33791 of the boot-to-title capture; k_8_8_8_8_GAMMA appears zero times
and color_exp_bias is 0 everywhere. Mechanism from Canary's own source:
k_8_8_8_8_GAMMA is the only colour format around which a PWL gamma<->linear
conversion is applied. So a renderer that linearises and re-encodes is doing
a different operation, and the difference is gamma-shaped and zero on
unblended pixels -- their reported signature.
Three rows the port is blocked on:
H3 -- 2 units per guest frame, measured on the plate's own ramp against a
pre-registration. Their 5 excluded by >2x, and the reason named: an alpha
step is not a clock rate without the element's declared T, and my own
splash-quad-timeline.txt published alpha against frame with no T column.
That file now warns at its head.
The title settle anchor is t~160, not t=118 -- it is ptcopyright, the last
build-in element and the only glyph one. Said plainly that this is the
reading under which their clock:'shared' collapses, and that a consequence
is not a counter-argument.
Told them NOT to change their 60 units/s yet: units/second is untouched by
this and two of my own captures disagree ~2.9x on frames->seconds.
The pad: sub_82457038 reads every field of XINPUT_GAMEPAD, 14/14 loads
verified against the image, plus a second keystroke-queue path. Flagged as
the superset the game can SEE, not the per-screen set, so it is used to
check a binding table and not to write one.
Play-test finding 4 asked, in order: is there a pass, what is it, where do
its parameters come from, only then what curve. All four, from GPU state.
1. NO post-process pass. Over all 1 048 draws of frames 4..226 (both boot
splashes): rt0=[tile=0 fmt=0 exp=0] on 1048/1048, pitch=1280 msaa=0 on
1048/1048, edram_mode only ever kColorDepth or kCopy, resolve dests only
the two alternating front buffers, and NO texture base anywhere in the
capture equals a resolve destination. The only texture bound in the whole
splash region is the sprite page 0x11A50000. No blur, no bloom, no fade
quad over a resolved image, no tone curve, no resolve-and-resample.
2. What it is: per frame, a full-screen replace triangle (the clear), a
full-screen black quad through the ordinary blend, ONE batched sprite
draw carrying every visible element (indices 4/8/12/24), and the two
presentation resolves.
3. Where the parameters come from: NOT the constant banks -- the splash
pixel shaders read zero float constants, ps_c[n=0] on 1048/1048, taken
off each shader's own float_bitmap. NOT immediates. The fade is the
per-vertex k_8_8_8_8 colour in a vertex buffer the guest rewrites every
frame.
4. The curve falls out of 3 and is the corpus's existing 34/frame law,
reproduced on an independent capture. Not claimed as new.
And the composite is ORDINARY SOURCE-OVER, confirmed from the shader ucode
rather than inferred from the blend register: the register reads
ONE/ONE_MINUS_SRC_ALPHA, which looks premultiplied, and is -- because the
shader premultiplies. The two together are src*A + dst*(1-A). So the 'more
pronounced' fade is neither a blend difference nor a pass.
The likely mechanism instead: the developer splash submits SIX quads, three
logos plus three slightly-larger companions that lead them by 8 frames and
are gone 79 frames early. Two over-blended copies of the same art at
different scale is a halo, on screen only during the entry.
Refutation attempt, recorded: REFUTED.md's re-opened rest() pair states its
settling condition as 'a draw capture of the developer splash naming which
of the three glows is submitted at rest'. This is that capture. All three
companions ARE submitted in all 21 frames -- so no rule that hides one
describes this stream -- but they are NOT interchangeable: Q6 leaves the
plateau on its own -5.6/frame decay while Q4 and Q5 hold 255. The one-byte
sibling difference is drawn.
Trap recorded with the evidence: censusing the whole 600-frame log finds six
640x360 textures sampled ~330 times each, which reads exactly like a
half-resolution blur chain. They are the attract movie's chroma planes and
first appear at frame 234, after both splashes. Restricting the window is
what separates them.
Evidence: docs/re/data/splash-draw-pass-census.txt,
docs/re/data/splash-quad-timeline.txt, docs/re/data/shaders/*.ucode.frag.
Logger: canary sylpheed-re d90d14e02.
The Port's standing ask list is not in my loop brief, which BLOCKED.md itself
records as having cost three sessions. My brief does force HANDOFF.md open every
iteration and HANDOFF is mine to write, so the pointer lives there. One line in a
file I own; no brief change and no human needed.
R11 says a cross-agent pointer must fail loudly when it goes stale, because every
staleness incident here has been silent. peer_asks.sh exits 2, 3 or 4 with a
message for a missing remote, a renamed branch or a moved file, and lists the
branches it can see so the fix is obvious. A blank output is a failure, not an
empty ask list.
Its own first version was wrong in the way this retro is about. Written as
`git show ... || { echo missing; exit 4; }`, piping it into `head` closed the
pipe, git died of SIGPIPE, and the fallback printed 'the file is missing' for a
file it had just printed in full. An error path that fires on success is worth no
more than one that never fires. Existence is now checked with `cat-file -e` and
the content exec'd; all four paths were exercised before this commit.

Delivered: T8aD +0x04 bit 0x02 selects additive, so the port derives the blend
instead of transcribing my table -- including for screens neither of us has
captured. With why I got it wrong first: the bit was already in REFUTED.md,
killed by a comparison of two renders made while our renderer had a stale
keyframe association, no leaf geometry and no rotation.
Their asks: pteff10 IS additive on the main menu, three sessions, every frame,
and my coverage table listing it uncovered there is corrected. The sweep ramp is
four leaf keyframes on the disc, with the oracle agreeing on sign and magnitude
and a second identification from the sub-128 alpha. And kind & 0x2 is not mine
to grant -- stated what the decode supports (0 violations in 15493 entries, and
it means the declaration marks the element focusable, not that the cursor can
reach it) and left the adoption to them.
ui-blend-mode-measured.md is superseded in its classification and keeps its
measurements, which are what the decode is fitted to.

ptframe4, pteff21/22/23 and pteff10 are ADDITIVE, measured. They were missing
because Canary's vertex dump was capped at two quads, not because the game does
not draw them.
The title: everything alpha-over except the sweep strips and ptbtn00f, the PRESS
(A) plate's focused variant, whose base is not -- which is what the pulse is made
of. And ptlogo_back2 / ptlogo_back2eff are alpha-over despite having every
surface property the ptframe* elements have, so the obvious generalisation is
refuted on the one screen that could test it.
The sweeps are on screen on the main menu and move between frames, in two
sessions at different phases.
And the coverage claim they checked was wrong -- five elements, not one -- with
the correction and their 'every button' point both recorded.

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.

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.

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 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.

Claude-Session: https://claude.ai/code/session_01Wuu56cE8vJGTBtn1ppsk8v
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.

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

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.

Claude-Session: https://claude.ai/code/session_01Wuu56cE8vJGTBtn1ppsk8v
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.

sylpheed-port's contract-check perturbs the FIRST occurrence of an anchor. My
supersession marker quoted the 'EXTRAS resets, the main menu persists' heading
verbatim, so the sentence appeared twice and the control read the untouched
duplicate and passed a wrong contract.
The marker existed because they had told me a grep lands mid-document, so the fix
for one navigation problem created another. Pointers now name their targets by date
and subject instead of reproducing the heading.

sylpheed-port pointed out that a newest-first convention protects a top-down
reader while a grep lands mid-document. Both of that section's claims have since
been overtaken -- the disagreement is settled at NEW GAME, and the persistence
question has been run -- and it carried no forward marker.
Kept rather than deleted: it is what the port was told at the time, and a reader
arriving by grep needs to know it was superseded.

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.

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.

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.

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.

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.

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.

Two iterations ago I corrected MISSION.md's stale "🔴 Emulator-side questions are
blocked" banner and wrote, in its place, that the two items it named were
"unblocked, not answered ... both need a running menu, both now have one, and
neither has been attempted". I wrote that without reading either page.
Reading them:
8AX vs ptbase was RESOLVED on 2026-08-29. Its status line says so -- both its
questions closed, page kept for the evidence.
The gamma control was attempted and half-answered, and its page records that
the run "needed the emulator only to BOOT, not to reach a menu ... parked behind
the title-screen blocker for no reason".
So neither item ever needed a running menu, and the section's premise was wrong
independently of whether the menu was reachable.
All three clauses false. The failure is specific and worth naming precisely:
replacing a stale status with an UNCHECKED one, in the same edit that criticised
the document for carrying unchecked status. sylpheed-port wrote a dead instruction
inside the commit fixing dead instructions; this is that shape, one document over.
METHOD: a correction is a new claim and needs the same check as the claim it
replaces. The urge to correct supplies confidence the correction has not earned --
check a replacement as hard as the thing it replaces, and hardest when the edit is
about checking.

I have been reading MISSION.md every iteration as instructed and never once
audited it, while auditing headings, instructions, env vars and fallbacks
everywhere else. It carried three false section headings, each superseded in
HANDOFF.md and nowhere else:
"🔴 Emulator-side questions are blocked -- the title is not reachable here"
False. Twelve emulator runs on 2026-08-30 reached the settled title, gated
on the plate pulse, and drove it into the menu, EXTRAS and out of the
archive. The two items the section named -- the gamma control and
separating 8AX from ptbase -- are UNBLOCKED, not answered, and neither has
been attempted. That distinction is kept.
"🟡 Needs one more run -- a Japanese-locale capture", describing "one capture we
cannot take". Taken twice, both committed, via jp_title_session.sh. And both
questions it blocked are closed, one of them confirmed against that very
capture. ⚠️ I noticed this section was stale several iterations ago, said so
in a message, and did not fix it.
"🔵 Needs a human decision -- rotation". Decided and implemented the day it was
raised: HANDOFF records "OPTION A IS DONE. The reference renderer rotates",
and ui_layout.rs carries the rotated blit with a control test pinning 0° and
360° byte-identical to the unrotated path. The field is now confirmed from
the ORACLE too -- +30/-45 predicting AABB heights of 1135.3 and 1301.1
against 1134 and 1303 measured, both under 0.2 %.
All three corrected leading with the correction, originals quoted and demoted
beneath. Only FACTS were changed; the questions and their gates are untouched,
since keeping the document true is maintenance and changing what it asks would be
overstepping.
METHOD: audit the document that defines the objective, because it is the one
nobody audits. A document read only for instructions is never read for review, and
the more central it is the more often it is consulted and the less often checked.

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.

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.

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.

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.

sylpheed-port refined my ranking: rank silent instructions above loud ones. All
of theirs were loud -- wrong paths that error out and announce themselves --
while mine was silent: an inert env var returning a clean, wrong result. Only the
silent kind manufactures evidence.
The silent surface is enumerable, so this is a sweep rather than a sample: every
environment variable the docs name, checked against the code.
SYLPHEED_KF_TIME_SHIFT was still live in FIVE doc files after I fixed one last
iteration. Two of the five were genuine hits rather than historical quotes:
ui-resting-pose.md -- a RESULTS TABLE ROW labelled "with
SYLPHEED_KF_TIME_SHIFT=1". Re-running it sets an inert variable, produces the
DEFAULT row, and lets a reader conclude the two readings agree. A stale
instruction inside a results table is the purest form of the evidence-
manufacturing class.
HANDOFF.md -- "experiment reachable via SYLPHEED_KF_TIME_SHIFT=1", a live
instruction in the delivery contract.
And a live gate exists under a DIFFERENT NAME that the docs never pointed at:
SYLPHEED_KF_TIME_LEGACY, verified read at ui_layout.rs:595 -- the parser itself,
not only the tests, so it does reach screen info and screen render. Both hits now
redirect there.
Beware the proxy, which is the trap the port named about their own "parsed"
check: absent-from-code also flags SYLPHEED_DISC, XENIA_SRC and SYLPH_ISO, which
are container paths the brief sets and no code reads. Absent-from-code is
necessary, not sufficient, and I checked each rather than reporting the seven raw
hits.

check counted more than the others
An answer not reachable from HANDOFF is not delivered, and this thread lived in
messages and docs/re/. Delivering it: the leaves ARE drawn and free-run on a
settled title, so a settled screen is not a static screen; the leaves are
identical on entries 4, 5 and 7; how the game advances them is undecodable with
reach, four models each refuted by a measurement; and keyframe_units_per_second
should stay put because the port's 1.87x table has an input now known to be wrong
rather than merely unpinned.
METHOD gains the lesson sylpheed-port named, which outlives the thread. Almost
every cross-check here runs disc -> exporter -> export against disc -> our reader:
two paths that agree because they read the same bytes with the same
understanding, and that agree anyway when the understanding is wrong. That is how
this corpus produced a build-ordinal error where everything still validated, a
two-era comparison with the same binary on both sides, and a rate confirmation
that was a prediction 20 % low meeting a measurement 50 % high. The chain that
counts ends at the ORACLE, and the single instance this week was the leaves'
rotation: +30 / -45 from the file predicting AABB heights of 1135.3 and 1301.1
against 1134 and 1303 in the draw stream. Before quoting an agreement, ask where
the two paths diverge -- if it is after the fact in question they are one witness
wearing two coats.
Also records that a refuted model is a result: four refutations, each with the
measurement that closed it, is firmer than any one of them fitting would have
been, because the failure this corpus keeps hitting is a model that fits for the
wrong reason and nobody checks.
