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 It carried three false section headings, each superseded in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.

The era test left one element responsible for all 74 507 differing pixels on
title_jp -- ptlogo_eff3.t32, the corpus's named plateau-less rest() discriminator
-- with two candidate rest poses, (108,72) stale and (98,42) fixed. There is a
capture of that exact screen, so the oracle can choose.
Scored over the 388x423 box where the two renders differ, so the result is not
diluted by the ~92 % of the frame that is identical:
stale era rest (108,72) RMSE 58.412
fixed era rest (98,42) RMSE 41.690 <- the game agrees with the fixed era
fixed era --settle t=213 RMSE 40.210
Until now the keyframe record-layout fix rested on internal consistency: 0 of
1 042 multi-segment alpha ramps constant-rate under the old reading against 857
of 1 540 under the new. Strong, but not a measurement of the game. It now has
one, on the single screen where the two readings change pixels.
Three controls, all run first. Alignment found by sweeping the vertical offset
rather than assuming it -- 45 gives 32.41 against 56.37 and 53.08 either side, a
sharp minimum at the known game-surface offset. The scoring box discriminates:
the same box against a different screen's capture gives 98-103 against 40-58
here. And --black changes nothing (58.412/41.690 either way) because every pixel
in that box is covered by an element -- recorded because the flag's help says a
framebuffer capture must be compared against a black canvas, and here it happens
not to matter.
Sweeping the screen's own timeline with --at gives the noise scale: the capture
sits on a plateau from t~135 to t~240, flat to 1.2 RMSE across 105 units, rising
sharply outside (78 at t=0 and t=270). So the stale-vs-fixed margin of 16.7 is
~14x that flatness and decisive, while the settle-vs-rest margin of 1.5 is INSIDE
it and is not. This capture separates the eras and cannot separate the policies;
the settle-instant proposal stays unadopted.
Refutation attempted: sylpheed-port's adjudication that their shipped pose is
closer to the game than their reference. It SURVIVES, independently and by a
different metric, in the same direction.
Also concedes that my "your branch is the stale era" reasoning was invalid -- I
inferred era from a line count, which is the error they named -- while recording
that the conclusion holds for the ref I could see: origin/auto/port-p6-audio's
ui_layout.rs is md5-identical to origin/main's.
METHOD: two things that should differ producing identical output is a broken
experiment until proven otherwise, and a zero is its most dangerous form. Four
instances now. Verify the inputs differ before believing the outputs match, and
do not infer that difference from a proxy -- line count is not era.

The reach test I deferred twice. sylpheed-port tested three screens across the
stale and fixed ui_layout.rs eras, found 0 differing pixels, and concluded the
eras explain nothing. Built both eras from source and rendered EVERY composable
GP_TITLE bundle through each.
7 of 16 differ. Entries 0-6, 8 and 9 are byte-identical -- which includes title
(4), main_menu (5) and extras (6), so the port's result reproduces for the
screens they picked. Entry 7 (title_jp) differs by 74 507 px, RMSE 12.409; the
two loading bundles by 49 771 px, RMSE 10.078; the four splashes by 23-33k px at
RMSE 0.94-1.78.
So "the eras explain nothing" is true for three screens and false for the
archive. It is specifically false for title_jp, which is one of the two rows
their check-all now allows BY NAME with the reason "rest-pose sparkles". Their
measurement of that screen was 0 and mine is 74 507; recorded with exact flags as
a disagreement for them to check, not adjudicated. Noted that their branch's
ui_layout.rs is the stale one (20 ins / 488 del against the pin), so a binary
built from their workspace HEAD is the stale era.
Two controls, both run first. The binaries genuinely embody the eras: build 5's
pteff00.prm reads `rest t=70 [12 70 80 -]` stale against `rest t=12 [0 12 70 80]`
fixed. And the renderer is deterministic: same binary, same flags, twice, 0
differing pixels on entries 7 and 12 -- without which every number is noise.
Mechanism on entry 7 is a single element, ptlogo_eff3.t32, rest (108,72) ->
(98,42). That is the element MISSION.md and ui-resting-pose.md already name as
THE plateau-less rest() discriminator, so the era difference on the JP title is
our existing open question surfacing rather than a new one.
And a trap: entries 10-15 differ by up to 49 771 px with NO rest position change.
The rest selection moves to a keyframe at the same (x,y) with a different scale
and alpha. My first extraction compared only the rest (x,y) column and would have
reported a difference with no cause. A pose is position and scale and alpha.

sylpheed-port's BLOCKED ask #2. The gap was the one quantity in the transition
with no rule: measured at 0, 3 and 2 frames across three transitions, and I had
proposed it might be a load, which would make it emulator- and storage-dependent
and unauthorable.
Leg 1, bundle size runs the wrong way. If the gap were the incoming bundle
arriving, the biggest bundle would gap longest. Build 4 is 12 278 666 B and gaps
ZERO frames; build 5 is 6 977 437 B and gaps 3 and 2.
Leg 2, ran title->menu a second time from cold. The outgoing ramp is
byte-identical (63, 127, 191, 255) and the gap is 3 frames in BOTH runs.
Leg 3, and the two runs are not a null comparison -- which is the objection leg 2
invites. The captures refute it themselves: press-to-first-change differs by ~12
frames between them (~25 against ~10). Something in this transition really is
cache-sensitive and moved by 0.4 s, while the gap did not move at all. The
control comes from inside the measurement rather than from an assumption that
conditions differed.
So the gap is deterministic to the frame and not a load. It is also not constant
across transitions (0, 3, 2, 3) and not in the fade group -- the port reports 866
keyframes across 16 screens with 0 untimed. A deterministic game quantity with no
rule found; black_hold_units stays 0, and "not a load" must not become a reason
to author a constant.
The load proposal in screen-transitions.md is marked refuted rather than deleted.
Also fills in docs/game/navigation.md, which the standing brief asks me to keep
and which I had not touched while measuring four transitions: a player-side
section on what a screen change looks like, and three scripting traps -- that
`pkill -f xenia_canary` kills the shell that ran it (cost a launch today, and the
same trap is already in METHOD for pgrep), that screen_id.py reports `menu`
during the attract loop, and that it cannot tell EXTRAS from the main menu.

sylpheed-port's BLOCKED.md ask #1. They declined to suppress their uniform
black_hold on the cancel path because (B) menu->title was one transition. The
test says they were right.
EXTRAS -> main menu, also via (B): the outgoing quad ramps frames 34-38 (5
frames, exactly build 6's declared 10 units), then frames 39 AND 40 are
completely empty -- 3 draws, zero textured, a harder black than either earlier
capture -- then the incoming menu's quad decays 41-45. So (B) does not imply a
cross-fade; menu->title is the outlier of three, and the generalisation I was one
step from publishing is false.
The screen was verified, not assumed. screen_id.py cannot separate EXTRAS from
the main menu, so which_title_screen.py checked the armed frame: extras 18.58 vs
main_menu 29.85, margin 11.27, inside the 9.9-11.7 band its control sets on four
known captures.
Three transitions now agree on one thing and disagree on another:
outgoing ramp = the declared final ramp, THREE FOR THREE, against three
different declared values (10u/5f, 8u/4f, 10u/5f), and exactly linear where
nothing overlaps it. Authorable from the file.
black gap = none / 3 frames / 2 frames. Not a per-button property, not a
per-direction property, not a constant. black_hold_units should not be
authored as one.
Build 5's incoming ramp is confirmed at 12 units by its RATE rather than its
count: the count came out 5 against a predicted 6 in both runs -- reproducible,
so not noise -- but capture 3's steps are -21, -42, -43, -42, i.e. 255/6 per
frame after a half-step start. Capture 2's decay does not fit that and is
unexplained.

Last iteration left an unidentified full-screen untextured quad decaying
255->15 during a menu->title transition, which build 5's declaration does not
account for. Hypothesis: it is the INCOMING screen's own pteff00, which opens at
a255 and clears. 8 frames matching build 4's declared 16 units is a FIT, so the
test was a transition whose incoming screen declares something else: title->menu
brings in build 5, 0->12 = 12 units = 6 frames. Prediction recorded before the
run.
Measured: menu->title decay 8 frames (incoming build 4, declared 8), title->menu
decay 5 frames (incoming build 5, declared 6). Different incoming screen,
different decay, in the predicted direction. The second is one frame short of
prediction, inside the documented +-1.
The tell that clinches it: a screen contributes TWO primitives, pteff00 at 255
and pteff02 at 64. The settled menu's untextured set is [64]; at frame 34 it
becomes [64, 255, 64] -- build 4's opening pair, which no single element
explains.
Bonus, and it closes the alpha puzzle: in capture 2 the outgoing quad ramps with
no other untextured quad present -- 63, 127, 191, 255, steps of exactly 64, four
frames, against build 4's declared 261->269 = 8 units = 4 frames. Exact and
exactly linear. Capture 1's 102/127/255 was a composite of two overlapping
quads, as sylpheed-port proposed.
The thing neither of us predicted: the two directions are not the same shape.
(A) title->menu is SEQUENTIAL with a real black interval of 5 frames (~10 units,
against the port's authored 9). (B) menu->title is a CROSS-FADE with no black
interval at all -- the incoming title starts drawing at frame 34, before the
outgoing menu's quad begins ramping at 40. Authoring one hold for both directions
inserts black that (B) does not have.
Also fixed: fade_pair.py's automatic rising/decaying classifier worked on capture
1 and produced nonsense on capture 2, where the title has no full-screen
primitive at rest and the heuristic latched onto a transient. It now prints and
does not decide.
Refutation attempted: sylpheed-port's structural prediction of a 6-frame decay
for an incoming menu. Measured 5. Survives as direction, one frame short as
duration; recorded as both.

sylpheed-port read the lead off the disc independently: content fade-outs start
at ptmsg 58, pteff10/pteff12/ptbtn05 60, against the quad's ramp at 70. That
reproduces my measured six-frame lead exactly (12 units = 6 frames) but has
content FINISHING two units before the quad starts, where I had published
overlap.
Checked which draws I had been watching. The content sprites are TEXTURED: they
fade over frames 34-37 and are gone by 39, and the black quad appears at 40 --
a one-frame gap, which is their two units. What overlaps the quad is a
different, UNTEXTURED full-screen quad decaying 255->...->15 across frames
34-41. It is unidentified: build 5 declares only pteff00.prm and a
single-keyframe pteff02.prm, neither of which is that decay. Recorded as an
open observation, not named from one capture.
So the shape is sequence, not overlap.
Also flagged, against my own interest: their "18 vs 19, one unit apart" compares
different intervals (content-start->black vs ramp-start->next screen), and the
capture's frame axis is not phase-locked to the file's unit axis -- the two
plausible alignments differ by two frames with nothing here to distinguish them.
So that agreement holds at one alignment and is not a confirmation. The quad's
alphas (102/127/255) also do not sit on a linear ramp across t=70->80, which is
unexplained.

screen-transitions.md carried a 14-unit "black hold" that the page itself
flagged as arithmetic rather than measurement. Measured it against the running
game; the guess was wrong, and finding the instrument to measure it turned up a
second, larger error in the same page.
1. fade_quads.py was STALE. It read each pose's time from blk+36 -- the next
record's time word -- the association the keyframe record-layout fix retired in
the crate. sylpheed-cli was rebuilt at the time; the Python helper was never
swept with it. Signature: it cannot time a group's last pose, so it printed a
trailing `t=-`. Fixed, controlled against the rebuilt `screen info` ([0 12 70
80] for build 5's pteff00.prm).
2. Through it, the page labelled the quad's CLEAR-hold as its fade-in and
published 0.87 s / 0.97 s / 4.08 s for a ramp that is 0.20 s / 0.20 s / 0.27 s.
A port pacing its menu fade-in off that would run it 5x too slow.
3. The measurement. fade_decompose.sh boots to the main menu, arms the UI draw
capture there, then presses (B), so one 260-frame window holds the whole screen
change. The fade quad is identified rather than guessed: a .prm carries no
tex[base=] and paints last, so it is the last full-screen untextured quad of a
frame. Control first -- the quad's ramp is decoded at 10 units = 5 frames, and
measures 4 submitted-frame steps with one unlogged frame in the span.
Result: content elements begin fading at frame 34; the black quad first appears
at 40 and is opaque by 43; the menu's last frame is 45; frame 46 has 6 draws
against 12. So the ~14 extra units are the content's own fade-outs OVERLAPPING
the quad's ramp, not a hold after it, and the inter-screen black is one frame.
Refutation attempted: sylpheed-port's entries 13/14 twins. Re-derived off the
disc -- 3.06 / 4.33 / 47.91, identical to two decimals. Recorded as confirming
their addressing and arithmetic, NOT as independent support: same renderer,
same disc, which is their own rule.
Reach: one transition, one run; the frame axis has gaps (232 headers over frames
3..260), so every span is +-1 frame.

Last iteration I retracted three claims because `--build 10/11` on GP_TITLE are
entries 12/15, and named the untested remainder in my own report: how much else
in the corpus used a build ordinal as an entry index. This is that sweep.
`screen --build N` indexes a predicate-filtered list, so every rejected entry
shifts every later ordinal. Disc-wide: 21 of 24 build-bearing archives diverge,
18 of them at ordinal 0 -- `--build 0` is entry 108 in each GP_MAIN_GAME_*2D,
24/26 in GP_HANGAR_ARSENAL/GP_READY_ROOM. GP_TITLE is the ONLY archive whose
first ten ordinals are the identity, which is the sole reason 207 of the
corpus's 226 build citations are safe. Second foot-gun: `--all` swaps the
predicate and renumbers 18 archives, so `--build N` and `--build N --all` are
not the same object.
The instrument failed its control first. A version using parse_build as the
predicate reported GP_TITLE as 16 builds, ordinal == entry throughout -- it
would have certified the exact bug it was built to find. The shipped version
uses the same predicates screen_builds() uses and reproduces `screen list` on
GP_TITLE exactly.
Audited all 226 citations. One real defect: a five-row table in
ui-keyframe-time-unit.md headed "declared element (build 11)" spans builds 10
and 11 -- palogo_sqex is in 10. All five placements re-verified and correct, so
the linear-ramp measurement is untouched; only the label was wrong. Fixed with a
per-row bundle column. GP_DIALOG --build 0 and GP_DEBRIEFING_PILOTLOG --build 10
re-run and reproduce.
Refutation attempted: sylpheed-port's corrected mid-ramp test rests on
ptlogo_all_eff holding a=127 from t=112 to t=246. Their quote is exact and it is
a plateau. The refutation fails; their correction stands.
METHOD already carried the rule I broke, and ui-splash-addressing already said
the splashes need --all. The failure was not missing knowledge -- it was
addressing a bundle by index without grepping for the index first.

Marks the two void splash rows in the capture-comparison data file, withdraws the
three claims in HANDOFF, and corrects the METHOD entry -- whose 'a gradient across
buckets is not a mechanism' near-miss was itself resolved by a counter-example
taken with the wrong index.
General form recorded: an index that silently means something else produces
well-formed output for the wrong object, and this project has now been bitten
twice from opposite directions with 'everything still validates' both times.

The under-10-units filter was documented and reasonable and wrong both ways: it
admitted the 10-19 bucket, the worst at 45.1 % mid-ramp, and excluded the two
splashes at width 8, the strongest evidence for the proposal it was serving. One
--settle invocation per screen would have shown this in seconds.
Plus the near-miss: the bucket gradient made 'narrow window means bad settle
pose' look obvious, and it is refuted by two screens inside the excluded band
that win by 75x and 33x. A gradient across buckets is not a mechanism.

The entry said a candidate-vs-incumbent comparison is the wrong shape of
experiment. Too strong. Two iterations later the same comparison adjudicated with
no new oracle, once a structural property was added that says which side is wrong
per disagreement -- does the chosen run contain the settle instant. Control 3072
of 3072; disagreements attributed 1036 of 1036.
Corrected rule: a bare comparison cannot adjudicate because a disagreement is
symmetric; it becomes decisive the moment a property breaks the symmetry per
case. Reach for an oracle when no such property exists, not as the first move.
With the tell that I had one available and did not look: I recorded the residual
as 'ambiguous by construction' and moved on TWICE without asking what would make
it un-ambiguous.

Plus the two companions: any statistic keyed on where an element's visibility
ends is near information-free here (87.8 % end at a=0 from the screen's exit
ramp, which bit both agents within an hour), and the port's mirror -- my
threshold-free 'nothing is held on this path' criterion is correct on the
fallback path and fails outright on the plateau path, so a cleaner definition
that fails a control is worse than an ugly one that passes.
HANDOFF carries the proposal with its evidence, its failed control, and an
explicit refusal to change rest() in a crate the port pins on the strength of
something I cannot validate from my own side.

From the port, and a better generalisation than mine. I had been filing my
failures under 'an external quantity caught it', which prescribes finding an
anchor; anchors are not always available. The port's title_jp error had none --
every control passed because the metric was fine and the error was which frame it
scored. What caught it was asking why rest produced that light, which exposed a
4-unit sparkle whose rest.t is its own peak.
So: state what the number means physically and see whether the story survives
contact with the data. A wrong frame yields a number with no physical story
behind it, which is detectable from the inside. It subsumes the null-as-result
cases too.
And a control does not test this: a control proves the INSTRUMENT and says
nothing about the SAMPLE.

The port's authored/flow.json stamped title/on_cancel_why = 'MEASURED, HANDOFF
Q5' for a clause whose evidence cell in the source table reads 'none'. It did not
invent that: HANDOFF's Q5 row opened with one **measured** covering six clauses of
different strength, and HANDOFF is the document it authors against.
Split per clause. Measured: initial focus varies; up/down move one item per press
and wrap both ends; left/right do nothing; B on a submenu restores focus 4/4; B on
the main menu goes to the title in <= 0.4 s with no loading screen. NOT measured,
evidence cell empty: 'no auto-repeat at the durations tried', and 'B on the title
-> nothing'. Both marked do-not-stamp.
Also splits the source table's own up/down row, which bundled 'one item per press'
(indirectly but soundly evidenced by the 4-press wrap count) with 'no auto-repeat'
(nothing behind it, and the hedge was carrying the claim).
METHOD entry: the failure is in summarising, not at either endpoint. The source
table was honest and the consumer cited its source; flattening six claims into one
adjective created a provenance nothing supports. A strength label is not
distributive.

Applying my own METHOD entry one iteration after writing it found four refuted
statements still asserted unmarked where a reader lands:
* envelope correlation 'has no resolving power' -- in three places including
HANDOFF. The port controlled the same estimator on a single track and got
r=1.0000 at zero offset; the saturation needs CONCURRENT streams sharing
timing. I agreed to this in a message and never landed it.
* '8 of 10 three-chunk regions' -- still asserted in HANDOFF in a different
section from its own correction.
* 'r9 is a wild pointer, never a guest address' -- still asserted inside the
kept-for-the-record section.
* the ALSA channel permutation, stated without scope, when a later capture
measured the identity and labelling from it put the silent channel on the
wrong name.
All four marked in place, striking the sentence and pointing forward.
Two lessons added: a 'kept for the record' section still asserts, so labelling
the heading is not enough; and naming a refuted claim keeps it greppable, so the
audit returns its own corrections as hits and every hit needs reading.
The first item is the one worth admitting: I acknowledged that correction in a
message, wrote the entry about corrections that never land, and then did not land
my own for a full iteration.

An A press produced no screen change; the obvious reading was that the button did
nothing. The log said the press was never delivered -- two file-pad vk=5800 lines
across the whole run is ONE press -- because it was issued 0.8 s after a screen
appeared, while the guest was loading and not polling.
The pad driver reports what it emitted, so a script checking its own output sees
success either way. Confirm the receiving side.
Generalised: when an action produces no observable effect, the first hypothesis
is that the action did not occur, not that it had no effect. The corpus has paid
for this twice -- here, and in the sign-in swallow where thousands of delivered
keystrokes were discarded inside the emulator and looked exactly like a dead pad.
Companion to the control entries: a control proves the instrument reads
correctly; a delivery check proves the experiment happened at all.

The port found its exporter still shipping 'no loop-point field has been
identified anywhere' in the field manifest.json concatenates, days after the
correction existed in other fields. Auditing this corpus the same way found the
same failure here: the refuted sentence was still standing untouched in
bgm-two-stems.md -- where anyone looking up BGM behaviour arrives -- and in
HANDOFF.md, the one page the port is told to read. My correction had gone into a
NEW page only.
Both fixed in place, each naming the refutation rather than quietly deleting the
old claim, and each carrying the measured window [9.44, 71.31] s at 61.87 s.
METHOD entry: writing a correction down is not landing it. Grep the corpus for
the CLAIM, not for the file you were working in. Plus the port's trap in doing
that audit -- a replacement that quotes the refuted sentence in order to name it
will match a substring search from inside the paragraph saying it is false.

Tailing the log from BEFORE the music starts cut the unsampled backlog from 616
samples spanning offsets 32..2,559,033 to 125 spanning 32..515,239, so the first
pass is sampled like any later cycle. Offsets below loop_start play exactly once,
which is why the previous run could not measure them.
Wraps at 96.46 / 158.33 / 220.21 s, gaps 61.87 / 61.87, both contexts together.
Two derivations, neither converting bits to seconds:
(a) time to read_offset crossing loop_start, plus a 1.33 s head correction at a
rate measured on 748 timestamped samples of that same stretch
(b) first pass (offset 32 -> loop_end) minus the cycle
Both give 9.44 s on both contexts -- four numbers, one value.
So the loop region is [9.44, 71.31] s of an 87.744 s wave, cycling every 61.87 s.
The first 9.44 s is an intro played once; the last 16.4 s, the fade-out
bgm-two-stems.md documents, is never played at all.
The decoder reads ahead of playback, but both endpoints are read_offset events so
the lead cancels in the difference. One boot, one bank.

My locator validated on slices cut from the wave itself -- found exactly, control
passed perfectly -- and the measurement was still ten seconds wrong, because
matching an exact copy is a different problem from matching a real capture and
music with repeated sections is where a locator aliases. Its clean +5.00 s
stepping showed self-consistency, which is also what an aliased lock looks like.
Paired with the port's mirror image the same day: an awk that read 0 for every
span produced a perfectly structured result agreeing with the hypothesis under
test, and its tell was that the CONFIRMING rows were impossible too.
Both point the same way: the tell is in the rows that agree with you. Checking
the disconfirming half harder is the intuitive discipline and it is the wrong
half.

No Canary patch was needed: UpdateLoopStatus already logs loop_start/loop_end,
they just need the Apu category (--log_mask=13 --log_level=3).
Decoded, from the menu, 8734 records all after BGM_103's contexts appear:
ctx0 (wave 3876864) loop_start 3605682 loop_end 25640423 loop_count 255
ctx1 (wave 3930112) loop_start 3539158 loop_end 26216351 loop_count 255
The movie's three ADV streams log NO loop records -- they do not loop.
Semantics visible in the trajectory: read_offset runs from 32 upward and 20 % of
samples sit below loop_start, so the stream plays from the beginning and
loop_start is where it returns AFTER loop_end. No wrap was observed -- the 45 s
hold ended with read_offset at 17 M against a loop_end of 25.6 M.
Two registered predictions REFUTED. loop_start is not ~0 but 11.6 % in. And a
linear bits-to-seconds conversion is invalid: it gives 62.34 s and 63.29 s for
two stems that must play sample-synchronously, which is impossible, so the data
refutes the assumption on its own.
That leaves a conflict I am not resolving: the field implies a cycle of roughly
[10 s, 72 s]; my audio tracking reported offsets 0.25..57.18 s. Recorded as
contested, with the likely weak link named as mine -- that locator's control used
slices cut from the wave itself, exact copies, which is an easier problem than
matching a real capture, and a control easier than the measurement does not bound
its error.
The port is told to change nothing: its trimmed 61.93 s loop is verified in its
own output, and the length survives better than the placement.

Pays the debt from the truncated audit. The census prints population, coverage
and skips in the same output, and ends with an explicit END line, so a cut-short
run cannot be read as a complete one.
POPULATION 104 movies; COVERAGE 95 resolved, 9 unresolved, 0 unreadable
70 one-chunk regions, 25 three-chunk regions
The port's 25 was right; my '8 of 10' was not a count.
Cross-referenced against the fix's own sweep, which also ran to completion
(78 + 17 + 9 = 104): all 17 changed regions are three-chunk, none is one-chunk,
and 8 three-chunk regions were never affected -- which the 1.5 MB cap predicts,
since a region only trips the filter if its span exceeds it.
So 'the defect is specific to the multichannel regions' survives with complete
populations on both sides, while 'all three-chunk regions were broken' does not.
The original 8-of-10 was wrong in its denominator and coincidentally shares a
digit with the 8 that are unaffected, which is the kind of resemblance that
carries a dead number into a later document.

240 s parked on the main menu, reached by using the XMA probe log as the screen
oracle instead of video -- the route the previous iteration wrote down. Menu in
26.8 s against never-in-378 s for the video rig, guest at 0.92x, capture at
0.08 % silence against the recipe page's own best of 0.31 %. BGM_103's contexts
verify the screen and no ADV context appears afterwards, so the attract loop
never took over.
Three results, two instruments.
NO SEAM: zero runs >= 0.3 s below median-18 dB in 232 s. The port's 3.4 s
near-silence is a property of its authored loop, not of the game.
NOT THE WAVE LENGTH: autocorrelation r at 87.750 s is -0.009 on four independent
windows; the top lag is 61.909 s with a 2x harmonic. Estimator controls recover
87.750 and 60.000 exactly.
61.93 s, INDEPENDENTLY: locating 30 s slices of the capture inside the decoded
summed waves shows playback advancing exactly +5.00 s per 5 s and wrapping at
61.93, from three wraps. Control: slices cut from the wave itself at 10/45/70 s
are found at 10.00/45.00/70.00. Two points mis-lock where the slice straddles a
wrap and they carry the two lowest scores in the table.
Offsets span 0.25..57.18 s of an 87.744 s wave, so the loop is [~0, 61.93) and
the final ~25.8 s is never played -- exactly where bgm-two-stems.md found the
fade-out and trailing silence. The game loops before the fade, which is why
there is no seam.
Also corrects my own '8 of 10 three-chunk regions start mid-stream'. The port
counts 25 three-chunk regions; it is right that both numbers cannot describe the
same set. My audit run was CUT SHORT -- the committed file ends mid-list with no
summary line -- so that was a ratio over an unknown fraction of the population,
and the claim that the defect is specific to multichannel regions is now
unsupported. The ADV verification and the fix's own sweep are unaffected; that
sweep ran to completion and printed its totals.

The voice-region truncation survived every test because there was nothing to
catch: the region parsed, the chunks decoded, the durations were self-consistent.
A missing third of a stream is smaller VALID output, and no check written against
our own output distinguishes that from correct output. What caught it was a
number from outside -- the running decoder's byte_sizes not fitting the region.
So: prefer at least one test per decoder pinned to something we did not produce,
and say so in the test, because the obvious maintenance of such a test is to
re-baseline it against current output, which deletes the only thing it was for.
Plus the port's corollary: it was checkable only because the identifier happened
to be a byte count. Index a handed-over result by a quantity the recipient can
test.

Completes ask #4. The three chunks were dumped from the resolved voice region
and decoded; the assignment is ctx0 -> FL/FR, ctx1 -> FC with LFE silent,
ctx2 -> BL/BR.
Two instruments failed first and both look like results, so both are recorded.
Envelope correlation with a per-pair lag search returns 0.86-0.95 for EVERY
chunk against EVERY channel, because all six residual channels share the
dialogue's activity timing -- that is an instrument with no resolving power, not
a finding. Sample-level correlation returns about zero, because the chunks do
not start with the movie and the XMA decode's framing offset is unknown.
Level settles it under the same 0.600 gain the bed uses: each stream lands
within 0.5 dB of exactly one residual pair and misses the others by 4-6 dB. The
ratio test is immune to chunk 0 being a clipped tail of ctx0 -- chunk0 - chunk2
is +5.88 dB against FL - BL at +6.18 dB, agreeing to 0.30 dB, where a swap would
be wrong by 11.76 dB.
Structural confirmation: chunk 1 is the only chunk with a digitally silent
channel and LFE is the only output channel with an empty residual (-115.73
dBFS), one to one; and the internal L/R correlations track the residual pairs'
(0.932 vs 0.918, 0.962 vs 0.929).
Worth having on its own: the same 0.600 scales both the movie bed and the voice,
so it is one mixer gain rather than two.
Reach: levels, not waveforms; one boot, one movie; and whether 0.600 is a fixed
constant or a volume setting is still unknown.

ADV.wmv carries ONE audio stream and it is wmapro 5.1, not XMA. Any framing of
the intro's audio as only 'which of three voice streams to ship' was missing the
bed.
Aligned the 148 s capture against that track (envelope r 0.769 against a median
of -0.001, refined to +224 samples, r 0.900) and solved
capture = g x movie + residual per channel.
The gain is 0.600 on every channel -- a uniform -4.44 dB, a mixer setting rather
than a fit artefact. LFE reproduces to -115.73 dBFS, 72 dB down, which is what
rules out codec difference as the explanation for the other residuals. FC is the
exception: the movie explains NOTHING of it (-0.09 dB), and the movie's own FC is
91.6 % silent.
The residual is three signals, not one: a front pair (r 0.918), a rear pair
(r 0.929), and a centre whose partner LFE is empty. The FC residual spans 34 dB
across 100 ms frames -- bursty, not steady noise.
That CONFIRMS the corpus's 5.1 reading, which voice-three-streams-are-concurrent
recorded as not established, and it confirms the specific detail it offered: that
the mono-in-stereo stream is 'a centre paired with a silent LFE'. Measured from
the output with no access to the stream contents.
Also corrects my own census page: it labelled channels with the ALSA permutation
[0,1,4,5,2,3] from the recipe page, which does NOT apply to this capture. The
6x6 matrix was computed assuming no order, every row's max falls on a distinct
movie channel, and the answer is the identity -- so the census's 'BR is 82 %
silent' was really LFE, reconciling with the movie's own 80.64 % silent LFE.
Reach: one boot, one movie; which XMA context is front/centre/rear is not
determined, only that the residual occupies those positions; and whether 0.600 is
a fixed constant or a volume setting is unknown.

Groundwork for the port's ask #4; it does not settle #4.
Captured the game's own output over the boot intro following the ALSA file-tee
recipe exactly -- paced pulse slave, --gpu=null, both mutes off. 148.02 s, 6ch
float32 48 kHz, 0.15-0.16 % silence against the 0.31 % the recipe page records
for its own clean run.
Provenance is the XMA probe rather than a screenshot, which is the right evidence
for an audio question: ADV's three contexts appear byte-exact (1294336 /
1118208 / 1171456), then the documented BGM_102 pair.
Five of the six channels carry distinct content; BR is 82 % silent and 11-15 dB
down. No channel is a copy of another -- the largest pairwise correlation is 0.70
between FL and FR.
That rules out a stereo mix, so 'ship one stream' cannot be right and the port's
held-wrong value stays wrong. It does NOT establish that summing is right, and
the 6-channel count is Xenia's hardcoded kFrameChannelsDefault -- what is
evidence is that five of them differ, which a stereo guest cannot produce.
NOT settled and named as such: the stream-to-channel mapping. The
cross-correlation of each captured channel against each decoded ADV stream has
not been run. One boot, one movie, and --gpu=null means no video cross-check.
Raw is 170 MB and is not committed; sent over share to the port.

The debt from two iterations ago. Two boots, same binary and ISO, one A tap
each, fired only after the plate's pulse had been seen for 12 consecutive
samples. ARGV recorded per leg, because the config dump provably cannot say.
leg A no profile flag 3811 swallow lines and climbing
leg B --logged_profile_... 0 swallow lines, final glyph 327 = MAIN MENU
327 is the documented main-menu glyph count, reproduced by this instrument's own
control, so leg B's press opened the menu. Capture committed.
Leg A demonstrates the SWALLOW, not the crash: I stopped it at ~2.3 M swallowed
calls because kernel tracing at log_level=3 was eating the 300 MB budget the
crash dumps need. The fault itself remains measured once, historically. One run
per leg.
A void pair came first and is recorded, because it is why the detector is what
it is. The first version fired on a single frame over a glyph threshold and hit
the INTRO MOVIE -- green flashes of 1298..5433 lasting under a second -- about
6 s before the title, in both legs. The presses were real (each skipped the rest
of the movie, which is Q9's behaviour) but the pair tested nothing. The fixed
detector requires 12 consecutive in-band samples, and was replayed against the
void runs' own series as its control: it declines the movie flash at 84.8/85.5 s
and fires at 93.9/94.7 s inside the sustained pulse.

Answers the port's ask #1, which it had flagged as the only one of its four
that could delete an authored entry rather than confirm one. It confirms one.
Held at the title with no input, the plate oscillates continuously: two windows
in one boot, 58 s and 57 s, ~23 cycles each, no decay. Periods 2.530 and 2.540 s
by upward mid-crossings -- 0.4 % apart.
It never goes off. The plate-absent floor is 159 green pixels, measured on the
committed live-title-build4-no-plate.png; the pulse bottoms at 714, 4.5x that.
So the port's 'flash and nothing after', reasoned from ptbtn00 expiring at
t=244, is wrong on the boot's end state -- ptbtn00f's 120-unit cycle is what
runs.
Instrument controls were run before it was pointed at anything unknown: the
glyph counter reproduces the documented 753 on live-title-press-a.png and 327 on
live-main-menu.png exactly.
Two estimators, and only one replicates. Mid-crossings agree across the two
windows to 0.4 %; a single-sinusoid least-squares fit does not (2.553 vs 2.413),
because the waveform is fast-rise/slow-decay rather than sinusoidal -- its own r2
of 0.468 and 0.228 is the tell. Both were controlled on synthetic sinusoids at
2.24/2.55/3.10 s laid on the ACTUAL timestamps and recovered every one exactly,
so neither is broken; one is misspecified. Recorded as such.
The wall-clock is 13 % longer than the corpus's earlier 2.24 s mean. Same
declared 120 units, different emulator pacing (x1.27 here against x1.12), so
this corroborates 'author the units' rather than disturbing it.
Reach stated: one boot; does not distinguish the boot title from an attract-loop
title; and the glyph count is a thresholded pixel count, so 714/1520 is not an
alpha ratio and no duty cycle can be read off it.

Two corrections from the port agent, both of which make earlier claims smaller.
1. Its 'reproduces your published centres to half a pixel' was model against
model. This corpus's 981/478 are the model's output at t=355, not the
capture's; the capture measured 992.0/467.2, the 11.5 px residual the page
declines to fit. So that control shows two implementations of one model
agreeing, not the model matching the oracle. Neither of us applied the
correlated-instrument test to that sentence at the time.
The discriminator survives: it asks whether two captures are the same frame,
and the model is monotone in t at ~4 px/unit, so a 42-unit gap cannot come
out of one frame however wrong the absolute times are. Recorded as such.
2. Running my 'grep for the symptom' audit against its own tree, the port found
the opposite failure: a control recorded in BOTH a tool table and a document,
drifted to 53.3 % and 53.2 %, with the evidence file gone so neither can be
re-measured. One hard-to-find record announces itself as missing; two
disagreeing records announce nothing, which is worse.
So the rule is not 'write it down twice' -- one record in docs/re/,
everything else cites it, and any number that must appear twice is generated
rather than typed.

Answers the open half of the A-press diagnosis, and most of the answer was
already in the tree.
The faulting runs booted with logged_profile_slot_0_xuid = "" -- their own
config dump -- while a profile existed (Found 1 Profiles). With nobody signed
in, A takes the state-0 branch of sub_821D03A0 and calls XamShowSigninUI(1,1);
Canary raises its Sign In dialog with a no-op close handler and nothing in an
unattended run dismisses it. 85 instructions verified against the image, 0
mismatches; the state-3 branch is XamShowDeviceSelectorUI, already ruled out by
storage_selection_dialog = false.
The correlation runs through the tooling: boot_menu.sh passes the profile flag
and Q4/Q5 pressed all five buttons; frame_clock.sh, which produced the faulting
run, does not.
So there is no blocker -- boot with boot_menu.sh. Flagged as retrodicted rather
than A/B tested, since I have not myself booted both ways and pressed A.
The uncomfortable half: canary-scripted-input-traps.md section 3 already named
the sign-in dialog WITH a committed capture, and boot_menu.sh's header already
carried the mechanism and the 8.4 million figure. The fault page searched for
the cause it had hypothesised and never searched for its own symptom. Added to
METHOD.md, along with the more expensive lesson -- a measurement whose only
record is a script comment is invisible to the document that needs it.
What this session did add is the join: that the known blackout is what drives an
unbounded guest queue into a failed 128 MB allocation.

The port ran the check and returned 294.9. Different frames; both measurements
stand. Its renderer also reproduces this page's published t=355 centres to half
a pixel on both quads, which is the control that makes the 295 worth anything,
and it confirms the 600/720 cycles from its own export rather than from the
header word.
Worth recording as method: the observable and the value were specified before
the port computed anything, so it produced the number without knowing whether
295 was the pass or the fail. Neither agent checked its own instrument with its
own instrument.

The port asked whether the refined sweep fit t=357.7 was measured against
live-title-build4-no-plate.png, because if so one of us is 42 units out.
It was not. 357.7 was solved against title-draw-capture-vertex-colours.log, a
GPU per-draw capture of the submitted vertex buffer -- four observables at once,
two quad centres and two vertex alphas. No framebuffer, no PNG.
The gap is not a fitting error either. Posing the leaves directly, t=400 misses
the captured quads by +169.0 and -172.2 px. Probe control: it reproduces the
page's published t=355 centres, 981 and 478, exactly.
Refutation attempted and FAILED: I expected the port's fit to be minimised by
the quad leaving the screen -- 'best fit' meaning 'draws least', the same shape
as the .tbm control that could not fail. At t=400 quad B is fully on screen and
quad A is 319 of 400 px. Their number is fitting something present and it
survives.
The real reason the two must differ is better than 'different frames'. The
sweeps are nested records on a free-running loop and their cycles differ -- 600
and 720, read from the record header +0x08 -- while the top-level clock stops at
settle. So two captures of the same settled title share a screen time and not a
sweep phase, by construction.
Consequence for the port: a sweep position does not date a frame; it gives a
phase on a 600- or 720-unit loop. And 357.7 is a joint fit over both leaves
while the port's ~400 poses one, so the two are not comparable in kind -- the
phases coincide only every LCM 3 600 units.
Discriminator handed to the port rather than taken: if its ~400 is pteff03 and
the frame is in the first cycle, pteff03a must be at centre 295 in that same
frame. The fit is against its renderer, so it owns the check.

Follows the necessity census. 'The order moves' is a property of the sort; the
tie-break work already found reorders costing zero pixels, so the picture
moving is a separate claim. Rendered each of the 62 deciding builds twice and
diffed.
38 .prm deciders: changed_px == ink_px in ALL 38. Without the rule the
primitive sorts last, paints over everything, and the
screen composites to pure black. The port's original
contradiction argument, measured on 38 builds across seven
archives instead of argued on two.
24 .tbm deciders: zero -- and that is MY INSTRUMENT, not a finding.
The control asked whether the composite had ink; it always does. The question
was whether the reordered ELEMENT has ink, and compose draws no pixels at all
for a .tbm. So those 24 zeros measure our renderer's blindness by construction.
tie_break_pixel_cost.rs already had the per-element ink_mask this needed.
Reported rather than quietly patched: a control that cannot fail is the shape
this corpus keeps paying for.
Also corrects two things the port agent caught:
- 'Two renderers, same answer' was true of the six GP_TITLE instances and not
of the other 74. The port's re-run of my probe is my code executed twice;
its independent leg was removing its own exporter post-pass, which covers
GP_TITLE only. The disc-wide 62 has one witness and the page now says so.
- forced_backdrop_necessity.rs defaulted to GP_TITLE with no argument, so a
bare run printed 6 instances in the same format as 80. It now walks every
dat/*.pak and reports the archive count.
