7a0318c2c0 port: a reproduce recipe naming a path off this repo is not a recipe
From the Decoder's catch at shutdown, not my own. They found their Canary logger
change -- the texture content hash -- living UNCOMMITTED in /canary, a checkout
pushed nowhere. Two committed findings could not be reproduced without it: it is
the field separating "the buffer rotated" from "a frame was decoded", and its
absence is what cost two withdrawn positions on units/second in one day. They
committed it and exported it into the repo as a patch.

Their generalisation applies here too, so I audited this side at the same moment.

One real instance: DECISIONS.md cited
`/reborn/docs/re/captures/main-menu-oracle.png` as the evidence for a decision.
The capture IS in the repository, at docs/re/captures/main-menu-oracle.png --
only the path was stale, left by the monorepo move. Fixed. The other /reborn
mentions are deliberate: one warns the mount is empty, one is a table row listing
the pattern as an example of what not to do.

⚠️ tools/port/check-citations does NOT catch this class, and the gap is named
rather than quietly left: it scans for REPO paths that fail to resolve, and an
absolute path is not a repo path, so it slips through. Extending it to flag
off-repo absolutes -- especially ones whose basename does resolve in-repo, the
recoverable case -- is the obvious next increment and is deliberately NOT done
here. It was found minutes before a shutdown, and a hasty checker is worse than a
named gap.

Index regenerated.

975d24def2 port: --linger, so a scripted walk can observe what arrives after it settles
Last iteration I inferred the returned plate's fade from code-path identity
because the harness could not watch it: `--script` quits the moment the last step
settles, and the plate arrives on its declared ramp ~3.6 s later. A film of
`--script=cancel` stopped at 168 units and never reached 214.

`--linger=SECONDS` holds the run open past the walk. `_script_settled` still waits
for a hold before shooting -- a shot taken mid-fade is a photograph of a fade --
this only changes what happens after the shot, which was "exit".

Pre-registered: the returned plate sits at its floor until 214 units, then rises
to full by 236, the same ramp the boot shows. Measured:

  units=208.75  0.145404   floor
  units=216.58  0.158596
  units=224.41  0.179036
  units=232.25  0.203050
  units=240.08  0.215005   full -- boot path gives 0.2142 at t=236

So the return fades, identically to the boot, and it is now OBSERVED rather than
argued from the branch it takes.

1c2782247d port: the plate POPPED on a return to the title where the boot fades it
The Decoder warned that my port "presumably models one title". Checking that found
a real behavioural split, and the code was right where I expected it wrong and
wrong where I did not.

My prediction FAILED first: I expected the port to be inventing a plate on a
(B)-reached title, because flow.json's scope_why says that is deliberately not
claimed. It is not inventing -- the call site cites a measurement from 2026-08-30,
the plate IS re-drawn after (B). scope_why was the stale thing, and is corrected.

🔴 BUT THE TWO PATHS DIFFER, AND A `why` CLAIMED THEY DO NOT. That call site says
"the plate re-appears by the SAME path, with the same shared clock, as it does on
boot. Whatever the boot does, the return does." Filmed:

  before: el=1.39 view_u=0.00 overlay_u=  0.00  plate absent
          el=1.53 view_u=8.67 overlay_u=244.67  plate present

The overlay clock jumped 0 -> 244.67 in ONE frame. The plate POPPED, where the
boot fades it across its declared 214->236.

Cause: `_overlay_process` detected "static diagnostic mode" as
`_sequence.is_empty()`, and `_sequence` is populated only by `--boot`. So `--menu`
matched it too and the menu's return took the `--screen --overlay` diagnostic
branch, which poses the overlay at settle_time() by design. A proxy for one mode
that silently caught another.

Fixed by gating on the flag itself -- `_static_overlay`, set only by `--overlay=`
without `--boot`. Verified both directions:

  diagnostic still poses: --screen=title --overlay=press_start --time=4
                          -> "overlay press_start at t = 240.00 units, drew 2"
  return now shares the clock: overlay_u == view_u on every filmed frame, plate
                          at its 0.1377 floor through 168 units
  boot path unchanged:    plate reaches full alpha at t=236, boot completes 10.46 s

⚠️ WHAT I DID NOT OBSERVE, stated rather than glossed: the plate actually RISING
on the return path. `--script` quits when the walk settles, so the film stops at
~168 units and never reaches 214. The rise is established on the BOOT path
(measured earlier: 0.1457 at 210 u, 0.2142 at 236 u) and the return now provably
takes that same branch with an identical clock -- but the final rise on this path
is inferred from path identity, not filmed.

⚠️ And whether the GAME fades the returned plate is still unmeasured. The 7.3 s
between (B) and the pulse returning is consistent with a transition plus the
declared fade, but that is consistency, not a measurement of the ramp on this
path. Recorded in scope_why.

Not settled: finding 3, no surviving cause; the clock origin, which the Decoder
reports blocked -- no capture contains the title, because it sits on the far side
of a 137.7 s movie and the runs were too short; the ~1.0-1.2 menu residual.

15702d0d05 port: the game's clock is frame-based, ours is time-based, and 60 is finally supported
The --framerate_limit=30 run refuted the time-based reading on every
discriminating row, against its author's own expectation: modal alpha step stayed
17 where time-based predicts 34, units/second halved to 30.2, the publisher dwell
doubled to 8.450 s. Both controls passed FIRST -- the limiter demonstrably took
effect, and all 8 splash quad rects were identical, so nothing but the frame rate
differed. 255 x 1 / 15 = 17 at 28.4, 51.4 and 54.8 presents/s alike.

THE GAME ADVANCES 1 UNIT PER PRESENTED FRAME. This port advances
`time_units += delta * units_per_second`. Two different mechanisms that agree at
exactly one frame rate -- 60 Hz, the only rate the console ever asked the game to
be right at.

🔴 DO NOT MAKE THE PORT FRAME-BASED TO MATCH THE GAME, and the reason is now in
authored/timing.json so nobody "fixes" it. A time-based port reproduces a 60 Hz
console on hardware that is not 60 Hz; a frame-based one drifts on every machine
that is not -- and this port has measured ITSELF between 9.7 and 69.4 fps
depending on the renderer. Matching the game's mechanism would import a fragility
the game never had to survive, because the game only ever ran on one box.

⚠️ BUT IT SHARPENS WHAT 60 CLAIMS. If units/second IS the present rate, then
`keyframe_units_per_second = 60` is no longer "the unit is 1/60 s". It is "the
game presented these screens at 60 Hz on the console" -- a harder statement, and
checkable.

 And supported for the first time. Canary unlimited presents at 51-55 Hz with a
splash dwell of 4.30/4.60/4.37 s. A natively 30 Hz game would present at ~30 in
Canary too -- the framerate_limit run proves it, since forcing 30 made that same
splash take 8.45 s. It does not take 8.45 s unforced. So the game asks for ~60.

Kept as `authored`, not promoted: this is inference over three measurements
rather than a measurement of units per second. It becomes `measured` when someone
reads the console's present rate for these screens directly.

🔴 AND IT CLOSES THE CONSTANT AS A CAUSE OF FINDING 3, in the direction that
matters. Under the frame-based model the only alternative is a 30 Hz console,
which puts the plate at 236/30 = 7.87 s -- LATER than the 3.93 s shipping, not
earlier. There is NO console present rate that makes the plate arrive sooner than
this port already shows it. The human reported it late; no value of this constant
can produce that.

The method note is theirs and it is the durable part: four positions on this
number were inference over a measured quantity; this one changed an input and
watched what moved. The opportunistic comparison -- two captures that happened to
differ -- pointed exactly the wrong way, because nothing controlled what else
differed between them. One designed capture settled it against its author's
expectation.

Not settled: finding 3, still with no surviving cause; the clock origin, which
they are taking next and which every ratio and count in this account survives;
the ~1.0-1.2 menu residual; the allowance's grep trigger.

c6b3256574 port: withdraw my "no hold" finding -- the port holds, and 60 is now positively supported
The Decoder withdrew 120 and returned to 60, which the port never left. Nothing
has to be undone. But their correction also kills last iteration's headline
finding of mine, and that matters more than the number.

🔴 WITHDRAWN: "the port has no hold" and "two errors that cancel".

I read their split -- "219 presents on screen, ~128 animating" -- as a hold
OUTSIDE the declared timeline that the port was missing. It is a split WITHIN it.
The publisher ramps 0-30, HOLDS 30-235 (205 units, 80.4 % of the screen) and
fades 235-255, and this port plays all three.

Measured rather than read. Frozen samples of the logo region:

  t=0.25 s (15 u)  0.390957   mid-ramp
  t=1.00 s (60 u)  0.405488
  t=2.00 s (120 u) 0.405488
  t=3.00 s (180 u) 0.405488
  t=3.80 s (228 u) 0.405488   identical to six decimals across 168 units
  t=4.20 s (252 u) 0.038142   in the exit fade

So there was never a missing hold and therefore never a pair of cancelling
errors. authored/timing.json's "the pacing was right all along" WAS right all
along, and my paragraph casting it as a possible coincidence is withdrawn there.

⚠️ The failure was not a mis-measurement. I took a two-part split from someone
else's instrument and assumed its boundary sat where my own model put it.
Presents are not units, and "animating vs holding" in presents does not decompose
the same way as "ramp vs hold" in declared units. That is a new failure shape for
this corpus and it is worth the name.

 AND THE DWELL FIGURES ARE NOW POSITIVE EVIDENCE, not survivors. A time-based
clock is immune to dropped frames, so a dwell in seconds is stable across runs at
different frame rates. The port's own splash dwell across a 4.0x change in its
rendering rate -- work done two iterations ago for an unrelated reason:

  17.3 fps -> 4.28 s     19.6 -> 4.26     25.0 -> 4.27     69.4 -> 4.26

a 0.5 % spread, putting 255 units at 59.6-59.9 units/s every time.

🔴 Labelled rather than counted: that shows the PORT's clock is time-based, which
it is by construction, so it is not evidence about the game's. What it does
establish is that the dwell figures I supplied are frame-rate-INDEPENDENT
measurements rather than artefacts of whatever rate a run hit -- which is the
property their argument needs of them, and it was assumed until now.

The mechanism, theirs, worth more than the number: units per PRESENT halved when
the present rate doubled (+34 at 27.2 presents/s, +17 at 51.4) while units per
SECOND did not move (54.4 vs 51.4). "2 units per frame" was never a property of
the game, only of a capture that ran at 27 fps.

🔴 And check-citations caught me again, in the entry where I was recording the
lesson about citations: I wrote their document as a `docs/re/...md` path that does
not resolve here. The check does not care about the disclaimer next to it, which
is correct. Named without a path now.

Finding 3 is OPEN AGAIN with no surviving named cause. Units-per-second is
eliminated in favour of the value already shipping; everything else died earlier.
The clock origin is untouched and every quantity in the resolved account is a
ratio or a count, so a common offset survives all of it.

c24ea3ba0e port: my falsifier was malformed, and following it through found two errors that cancel
CONCEDED. I set the falsifier as "at 120 the publisher splash runs 2.125 s against
cold boots measuring 4.30/4.60/4.37". 2.125 s is the declared ANIMATION length;
4.3 s is how long the SCREEN is up. The screen holds after the timeline ends, so
those are different quantities and the comparison would have found a contradiction
at ANY units-per-second.

The Decoder also checked the defence I handed them -- that the dwell corpus might
be emulator-contaminated -- and declined it. Their capture reproduces those boots
(publisher 4.263 s, developer 3.457 s, four runs agreeing). They could have waved
my numbers away and did not.

🔴 BUT FOLLOWING IT THROUGH FOUND SOMETHING NOBODY HAD SAID: THE PORT HAS NO HOLD.

  publisher   declared 255 units  measured 4.270 s  animation at 60 = 4.250 s
  developer   declared 210 units  measured 3.527 s  animation at 60 = 3.500 s

The port's screen time IS its animation time; the residual is +0.02 s, i.e. none.
The game, by the Decoder's counts, is on screen 219 presents and animates ~128 of
them -- about 42 % hold.

So if 120 is right, this port makes TWO ERRORS THAT CANCEL: it animates every
splash 2x too slow, and it omits the hold entirely, and the two sum to almost
exactly the right total screen time.

That is why the dwell check passes, and authored/timing.json cited that agreement
as proof -- "So the pacing was right all along and nothing changes in the code."
Conditional on 120, that sentence is a coincidence. Corrected in place.

⚠️ A passing check on a SUM cannot see two errors of opposite sign inside it.
Fourth member of today's family, after the non-inverting latch check, the
unguarded buffer assumption, and the segmentation that nearly produced a
convenient answer.

🔴 AND 120 EXPLAINS BOTH OPEN PLAY-TEST FINDINGS. 60 EXPLAINS NEITHER.

  finding 3, "the plate arrives late":
      at  60  full at 3.933 s        at 120  1.967 s
  finding 4, "the game's fade is MORE PRONOUNCED":
      at  60  build-in 0.750 s, then the screen leaves at once
      at 120  build-in 0.375 s, then the screen HOLDS ~1.7 s

At 60 the logo drifts in slowly and leaves; at 120 it snaps in and sits, which is
what "more pronounced" describes. Finding 4 is explained twice over by one
constant -- the fade is 2x slow AND the hold is missing. Every named cause for
both findings has died over the past several iterations; 120 is the first
hypothesis that accounts for either, and it accounts for both.

This is not a measurement and I am not calling it decisive. It is the one thing
the port can contribute that no capture can: what a human watching both reported.

STILL HOLDING AT 60. Reach is one boot and they are not asking me to lift it.

⚠️ The hold and the constant are COUPLED. At 60 the port must NOT gain a hold --
the animation already fills the screen time and a hold would overshoot by ~40 %.
The missing hold is a defect only if 120 is right. When it moves it is TWO
changes: the constant, and a hold measured as (screen presents - animation
presents), which must NOT be inferred from the total -- the total is exactly the
quantity that cannot distinguish the two errors.

Not settled: the constant; the clock origin; the ~1.0-1.2 menu residual.

07da4f167f port: hold at 60 against a better 120, audit the switch, and name its falsifier first
The Decoder measures 120 units/s with a content-hash experiment carrying the
controls the withdrawn version lacked -- a static texture hashing constant (1
change in 403 samples) and movie luma not constant (102 distinct) -- against
pre-registered bands the observed 0.5739 falls inside. It is a better experiment
than either it replaces.

THE PORT HAS NOT MOVED. It is their third position on this number in one day,
reach is one boot, and they said themselves that a second independent boot before
a timeline is rewritten is the defensible call. Agreed.

⚠️ And 60 is not defended either -- its bracket was withdrawn this morning. Both
numbers are undefended. The port keeps the one it ships because switching on a
single capture is a worse failure than holding on none. That is the whole
reasoning and it is not evidence about the game.

 THE AUDIT THEY ASKED FOR COMES OUT CLEAN. "If seconds are baked in anywhere,
they all move." No seconds are baked into the timeline: every second this port
prints or acts on is computed as units / keyframe_units_per_second at the point of
use -- settle_time, exit_time, _overlay_quit_at, the boot log. audio.json's
loop_start_s / loop_end_s ARE seconds and correctly do NOT follow the constant;
they are positions in an audio file with no keyframe unit in them. So the switch
is one number in one file.

🔴 ONE EXCEPTION, AND IT WAS HIDING BEHIND A COMMENT ABOUT NOT DRIFTING.
tools/port/verify-dwell read black_hold_units from the authored file "so it cannot
drift again" -- and then divided by a literal 60.0. The value could not drift; the
conversion could, and would have gone silently wrong the moment the constant moved,
which is under active dispute right now. Harmless only because the hold is 0.
Fixed to read the rate from the same file it already opens.

That is the third time in this corpus a `why` has described a property the code
did not have, and the first where the comment and the defect were one line apart.

📌 AND THE FALSIFIER IS PRE-REGISTERED, BEFORE ANY SECOND BOOT, in
docs/port/units-per-second-switch-readiness.md. At 120 every declared interval
halves: the plate lands at 1.967 s, the publisher splash runs 2.125 s and the
developer 1.750 s. Three cold boots measured those splashes at 4.30/4.60/4.37 and
3.51/3.50/3.37.

So 120 and the dwell corpus cannot both be right in wall-clock seconds -- the same
collision that killed the 35 units/s proposal from the other direction, arriving
from the opposite side. Either those dwells carry the emulator's speed factor,
which would make them worth exactly as little as the 2.13 s route the Decoder has
already declined to lean on, or 120 is wrong. Naming that now is the point of
writing it before the boot rather than after.

What would move this port: a second independent boot agreeing, AND a statement on
whether the cold-boot dwell corpus survives the same speed-factor objection that
the 2.13 s route does not. The first without the second leaves a 2x contradiction
standing between two numbers the port would then hold at once.

Not settled: the constant; the clock origin, which every ratio and count above
survives untouched; the ~1.0-1.2 menu residual; the allowance's grep trigger.

b42ff385ed port: my 12-unit bracket is withdrawn, and 41 % of my own doc citations did not resolve
Two things, and the first is a refutation of mine that lands.

1. THE 12-UNIT BRACKET IS WITHDRAWN. It excludes nothing.

I kept 60 units/s on the ground that "12 declared units measured at 0.14-0.30 s
gives 40-86 units/s, so 120 is excluded". The Decoder refuted it and I checked
the arithmetic myself:

  120 units/s predicts 12 units in 0.100 s -- BELOW the sampler's own 0.125 s
  resolution, which the source doc states in its own words ("at a sampling
  resolution that cannot do better"). A 0.125 s sampler reports such an interval
  as about one sample, ~0.125-0.14 s. So the 0.14 s low end is the INSTRUMENT'S
  FLOOR, and 12/0.14 = 85.7 is an upper bound produced by dividing by a floored
  duration. It is the value 120 predicts once the sampler is accounted for.

🔴 And the deeper error is mine rather than the arithmetic. I argued the leg
survived because it "never touched a frame count". True, and INSUFFICIENT: every
wall-clock duration off Canary is true/speed_factor, so apparent units/s = true x
speed, and the speed factor is precisely what makes the three routes disagree. I
checked the leg for the WRONG CONTAMINANT. Frame-free is not clock-free, and on
this emulator clock-free is the property that matters.

What survives is the half I did not lead with: the declared 12 units are
independently confirmed as SIX FRAMES by screen-transitions.md's 255/6-per-frame
ramp, with no wall clock in it. That is evidence about units per FRAME -- never in
dispute -- and silent about units per second.

So 60 has NO surviving bracket. It stays because nothing supports 120 either and
moving a shipped timeline on no evidence is worse. That is a default, not a
derivation, and the entry now says so. `kind` is already `authored`.

2. 41 % OF THE REPO PATHS CITED IN MY OWN docs/port/ PROSE DID NOT RESOLVE.

The Decoder observed that everything they hand me links into docs/re/ files that
live only on their branch, so every link they send dangles from here. I turned it
on myself and it was worse than I expected: 37 of 91, in two classes.

  19  on their topic branch -- real files, not merged. Not errors, and no one in
      this container can fix them; the fix is a merge.
   7  resolve NOWHERE: docs/BLOCKED.md, docs/DECISIONS.md, docs/FORMAT.md,
      port/manifest.json, port/screens/title/*.json. Left behind by the monorepo
      move and the export/ rename. Simply wrong -- a reader following one gets
      nothing, and nothing had ever told anyone.

All 7 fixed. audit-kinds checks citations in authored/; nothing checked the
PROSE, which is where this port explains itself.

New: tools/port/check-citations, wired into check-all with its control. It fails
ONLY on the resolve-nowhere class and reports the peer-branch class, because a
check that went red for a state nobody here can change is the shape the display
guard exists to prevent. The --selftest plants a dangling citation and requires it
caught, AND a real one and requires it passed -- both directions, since a scanner
that flagged everything would also "pass" the first.

Not settled: finding 3 has no surviving cause and 60 now has no surviving
derivation either; the ~1.0-1.2 menu residual; pgloading_loop5's residual; the
allowance still waits on its grep trigger.

3df042f10f port: the re-opened rest() pair reaches nothing we draw, and 60 units/s is authored now
Two things, and both are about a label being wrong rather than a value.

1. THE rest() PAIR IS MOOT FOR THIS PORT, and that is measured rather than
waited on. R1 re-opened both legs, 8 further claims died with the
⟨render-vs-capture⟩ instrument, and ScreenView.settle_time() uses rest.t -- so
this port has been sitting on a question with no instrument behind either side.

An element reaches the plateau-less fallback exactly when no two consecutive
keyframes are identical. Census over all sixteen screens at every nesting depth:
FIVE elements, three distinct -- palogo_sqex_eff, palogo_anima_eff, ptlogo_eff3,
plus two region twins.

And every one of them is transparent where its rest pose is read:

  publisher_logo   t=140         not drawn: palogo_sqex_eff  (transparent)
  developer_logos  t=117         not drawn: palogo_anima_eff (transparent)
  title_jp         --pose=rest   not drawn: ptlogo_eff3      (transparent)

So no rest() rule -- plateau-plus-dwell, `last`, `maxalpha` or `lastall` -- can
change any pixel this port draws. That is why the splash rows score 0.01 %
against their captures while resting on a heuristic nobody can currently defend:
it is not load-bearing there.

🔴 And the brief's "the two splashes are the ONLY screens reaching that fallback"
is narrowly refuted -- title_jp reaches it too, via ptlogo_eff3. Stated as a
measurement of the CURRENT export: the record-layout fix re-timed keyframes
corpus-wide and a plateau is exactly what that could create or destroy, so this
does not say the claim was wrong when written.

⚠️ It does NOT rehabilitate rest.t, still wrong for transients like
ptlogo_back2eff1 whose rest.t=54 is a two-frame flash's PEAK. That is a plateau
case, not a fallback case, and nothing here touches it.

2. keyframe_units_per_second RECLASSIFIED measured -> authored. The value does not
move; the label was false. The Decoder withdrew their guest-frame-rate finding
the same day they published it, and this file carried `kind: measured` on its
strength. Three routes now disagree -- withdrawn movie cadence 60, vblank ~120,
title-plate-delay ~56 -- and at most one is right.

60 is kept, and not as a coin toss: the one leg of this file's own reasoning that
never touched a frame count still brackets it. The transition quad is declared
black for 12 units and the capture measured 0.14-0.30 s, i.e. 40-86 units/s. 60
sits inside; 120 does not; ~56 is 7 % away and inside the same bracket.

🔴 audit-kinds caught my first attempt at this, DANGLING: I cited
guest-frame-rate-WITHDRAWN.md, which is on their branch and not in my checkout --
citing a document I cannot read. The check doing exactly its job. The withdrawal
is now named in prose and labelled as coming from their message.

📌 Their method note is worth more than the number and is recorded in the file:
their pre-registration named three ways the ruler could lie and guarded two; the
third occurred, and a PERFECT 1.0000 is precisely what it produces. A clean result
on an instrument whose key assumption is unguarded is not confirmation -- the
cleanness may be the failure mode's own signature. Same family as this port's
non-inverting latch check, which passed for the wrong reason until its control
failed.

Not settled: finding 3 still has no surviving cause; the ~1.0-1.2 menu residual
against the additive-capable reference; pgloading_loop5's own residual; and the
allowance still waits on its grep trigger.

94e44b5ba4 port: the additive-capable reference collapses the divergence 6x, measured at the tag
The Decoder taught `ui_layout::blit` the additive blend at
formats-pin-2026-09-01b, on the argument this port made: the comparison was
structurally incapable, and the refutation keeping additive out was
⟨render-vs-capture⟩ -- that renderer disagreeing with itself while it had a stale
keyframe association, no leaf geometry and no rotation.

MEASURED WITHOUT PULLING THEIR BRANCH INTO MINE: a detached worktree at the tag,
sylpheed-cli built there, verify-screen pointed at it through SYLPHEED_CLI. My
branch is untouched and the reference on `main` is unchanged.

Pre-registered: the diffs caused by the gap should collapse, and whatever remains
is a different cause.

  main_menu     7.2580 max 105  ->  1.2068 max 28   6.0x
  main_menu_jp  7.3440 max 108  ->  1.2111 max 31   6.1x
  extras        6.9757 max 113  ->  1.0229 max 28   6.8x
  extras_jp     7.0734 max 115  ->  1.0255 max 30   6.9x
  title         1.0335 max  88  ->  0.5685 max 41   1.8x
  title_jp      4.4944 max 233  ->  2.8225 max 233  1.6x
  build_12/15   0.0772 max  60  ->  0.0463 max 17   1.7x
  build_00/01   0.0676 max  60  ->  0.0366 max  4   DIFFERS -> OK

build_00 and build_01 stop differing entirely, over3 3422 -> 0.

And the twins agree to a third of a percent: main_menu 1.2068 vs main_menu_jp
1.2111 (0.36 %), extras 1.0229 vs extras_jp 1.0255 (0.25 %). Under the name-keyed
map those pairs were 4.1x and 7.8x apart. Nothing was fitted -- they converged
once when the PORT took the decoded field and again now that the REFERENCE draws
the same blend.

The residual is smaller and its causes are the documented ones: title_jp 2.82 is
the --pose=rest sparkle handling, title 0.57 the ptloop sweep phase, both
untouched by any of this. main_menu/extras and twins sit at ~1.0-1.2 max ~28-31,
new and undiagnosed -- additive was the dominant cause, not the only one. And
build_12/15 do NOT return to their pre-change 0.0368, so pgloading_loop5 carries a
small residual of its own beyond the blend. Recorded, not chased.

🔴 THE ALLOWANCE SHOULD NARROW AND HAS NOT, ON PURPOSE. Its justification is gone,
but check-all builds the reference from the WORKSPACE crate and the additive path
is at a tag, not on `main`. Narrowing now would turn check-all red against a
reference that still cannot draw additive -- a wall of failures meaning one thing,
which is the defect the display guard exists to prevent. The trigger is written
into the script so it does not rot: when `grep -q additive
crates/sylpheed-formats/src/ui_layout.rs` succeeds, drop the export-derived clause
and keep the two named legacy rows. The set that should then differ is measured
above.

H5 confirmed from the other side. And a trap worth carrying: the Decoder nearly
reported my H5 claim as a contradiction because `loop5` is not a sprite -- it is
an ELEMENT, pgloading_loop5.rat, resolving to sprite pgloading_ring.t32. Any
census keyed by sprite name will miss it.

Not settled: the ~1.0-1.2 residual on the menus; pgloading_loop5's own residual;
finding 3, where the Decoder is taking the clock origin; and the 8 claims R1 has
re-opened against ⟨render-vs-capture⟩, including BOTH legs of the rest() pair
that this port's settle behaviour rests on.

c01580740e port: my pteff10 counter-example failed, H5 closes as additive, and I broke my own allowance
Three things, and the first is the one worth reading.

 MY COUNTER-EXAMPLE FAILED. I reported pteff10 as a possible counter-example to
the  DECODED blend bit. It is not: the oracle measures it ADDITIVE on main_menu
in all three menu sessions, every frame, entry 5 of blend-bit-vs-oracle.txt.

My premise was a stale COVERAGE TABLE of theirs, sitting upstream of its own
correction. I inferred "their log does not cover this element" from a summary and
called it a contradiction with a capture. The lesson is not that their table was
stale -- it is that I treated a summary as the log, having spent three iterations
insisting that other people quote instruments rather than conclusions.

Their explanation made a prediction, so I checked it rather than accepting it:
if additive and alpha-over nearly coincide on a dim glow, why did my score move
20 %? Diffing the two renders, where pteff10's blend is the only change:

  identical        373 588 px (40.5 %)
  differing > 3    330 794 px (35.9 %)
  MAX difference   32 levels        pixels >= 60:  0

Their explanation holds and my scepticism does not. Nothing moves more than
32/255. What moved the RMSE is AREA.

📌 And that generalises past this row: raw-rmse is AREA-WEIGHTED, so a shallow
change over a third of the frame moves it far more than a deep change over a few
hundred pixels, and the number alone cannot say which you have. 10.88 -> 13.02
reads like a serious regression and is invisible to an eye. Any verify-capture
row that moves should be asked "broad or deep?" first; it costs one histogram.

I did NOT take their suggestion to exclude the element from the metric. The
reason to exclude -- "the metric cannot distinguish these" -- is now measured to
be false; it distinguishes them fine and weights them by area. Excluding would
remove the only signal that would fire if the bit were wrong elsewhere.

 H5 CLOSES, as a side effect. pgloading_loop5 -- the element I had localised all
951 differing pixels to -- carries blend_additive, and ui_layout.rs has no
additive path, so the reference cannot reproduce that draw by construction.
build_00/build_01 agreed only because they never draw it; with the decoded field
they gained loop1/loop4 additive and now differ too, as predicted.

🟢 The strongest corroboration of the decoded field came unfitted, from the rows I
was not looking at. EN/JP twins were 4.1x and 7.8x apart under the name-keyed map
and are now 1.1 % and 1.3 % apart (main_menu 7.26 vs 7.34, extras 6.98 vs 7.07).
A disc-wide field predicts locale twins render identically; a screen-name map
cannot. That prediction was not available to me before the swap.

🔴 AND I BROKE MY OWN ALLOWANCE, silently, one iteration after building it.
check-all's verify-screen allowance derived from authored/rendering.json's
additive_elements -- the key I deleted last commit -- so it evaluated to EMPTY and
would have failed six rows for no reason anyone could read off the output. Caught
by going to look, not by the check. A derived allowance is only as durable as the
thing it derives from, and I pointed this one at a file I then emptied.

It now derives from the EXPORT. ⚠️ That is LOOSER and the cost is stated: 12 of
16 screens qualify and verify-screen goes fully green. Measured after the swap
the two sets line up exactly -- all 10 differing screens have a drawn additive
element, all 6 agreeing screens have none -- but a screen differing for some
OTHER reason would now be excused. 📌 The real fix is not here: verify-screen
compares two renderers and one cannot express a blend the disc declares. Giving
ui_layout.rs an additive path would make it meaningful again. PROPOSED, not done
-- their crate, and their refutation of additive predates the measurement that
overturned it.

Not settled: finding 3, which now has no surviving named cause at all -- the
Decoder is taking the clock origin, on the grounds that every measurement either
of us has made is a DIFFERENCE and a difference cannot detect a common offset.

70799488fe port: delete the authored blend map for the decoded field, and find a counter-example doing it
PORT-MISSION §3: "When the RE agent later decodes something you had authored,
delete the authored entry and let the exporter emit it. That deletion is the
measure of progress." This is that deletion.

authored/rendering.json's `additive_elements` -- a per-screen list transcribed
from the Decoder's per-draw RB_BLENDCONTROL0 log -- is gone. The exporter emits
`blend_additive` per element and per nested focus/leaf element from `T8aD +0x04`
bit 0x02, and ScreenView reads it there. Both accessor spellings are needed:
`ptbtn00f.t32` is in build.sprites while no element carries it as `sprite`, and
it is the sharp case -- the plate alpha-over, its own glow additive, adjacent
draws on one screen.

CHECKED BEFORE THE SWAP, and the map turned out to be a SUBSET, not the answer:
15 elements it called additive the disc agrees with, ZERO contradictions, and 17
MORE the disc marks that it did not. Those include the sweep LEAVES (draw_leaf_for
means pteff03/pteff03a are what reach the screen while the map listed their
parents) and TWELVE on `title`, where the map was deliberately empty -- so the
port has been drawing every title effect with the wrong blend.

H6 closes with no capture at all: the JP asymmetry was an artefact of a
NAME-KEYED map, and the bit is on the disc for every screen at once.

🔴 AND IT INTRODUCED A REGRESSION, WHICH IS REPORTED, NOT HIDDEN. Against the
oracle captures on the GPU: main_menu 10.88 -> 13.02, main_menu_options 11.56 ->
13.57. Deterministic to the digit over three runs, so not sampling noise.

Isolated to ONE element, with a control:
  - main_menu's only newly-additive top-level element is pteff10;
  - extras gained none and did not move -- the same change on a screen with
    nothing new moves nothing;
  - the leaf rule was disabled separately and main_menu stayed at 13.02, so
    pteff03/pteff03a are NOT the cause. That prediction of mine failed; the rule
    is restored, being provably neutral here;
  - title did not move despite twelve newly-additive elements, consistent with
    verify-capture posing at settle t=198 where those quads are transparent.

That is a potential COUNTER-EXAMPLE to a  DECODED claim, and it is a sharp
question rather than a guess: their own map lists pteff10 additive on `extras`
and not on `main_menu`, and they logged BOTH screens. Asked in BLOCKED.md H6.

Shipped anyway, for reasons stated rather than assumed: +2.14 is inside the
harness's own ±3.78 capture-phase term for that screen and cannot adjudicate a
disc fact; the decoded source is far better evidenced (35 elements, zero errors,
out-of-sample prediction 3 of 16); and fitting an exception for one element would
put an authored entry back to make one number smaller, which is the move this
project keeps having to undo. It is a KNOWN regression, not an unnoticed one.

Also settled this iteration, for the Decoder's open question: the port FADES the
plate, it does not pop it. Frozen sweep of the plate region -- 210u 0.1457,
216u 0.1573, 222u 0.1727, 228u 0.1900, 236u 0.2142 -- a clean monotone ramp
across the declared 214->236. So t=236 is the port's COMPLETION, not its onset,
and the 0.367 s "late plus a pop" reading does not apply.

Not settled: whether pteff10 has a counter-example; H1's repeat half; the four
red verify-screen rows; and finding 3, which still has no cause now that units/s
is settled at 60.

7dd754f8e4 port: bump the formats pin to formats-pin-2026-09-01 for the blend accessors
What I wanted from the new state: `ui_layout::sprite_blend_additive` and its
three siblings, which expose `T8aD +0x04` bit 0x02 -- the decoded blend mode.

Until this tag, `Element` surfaced `kind` (+40), `parent`, pivot, keyframes and
`focus_link`, all from the RATC record, and nothing reached the sprite's own
header. That is why the port has been carrying an authored additive map keyed by
SCREEN NAME, transcribed from the Decoder's per-draw RB_BLENDCONTROL0 log, which
cannot answer for a screen nobody drove the game to -- the Japanese menus being
the case that raised it.

Both spellings are needed, not one: `sprite_blend_additive` takes an &Element,
and `blend_additive_by_name` takes a sprite name, because a button's focused
variant is reached through focus_link and `ptbtn00f.t32` is in build.sprites
while no element carries it as `sprite`. That is exactly the sharp case in my
own map -- press_start's only additive entry IS ptbtn00f.

Pin bumped as its own commit, per PORT-MISSION §2. Nothing else in this commit;
the exporter does not read the new accessors yet.

7c8e4a863a port: adopt the game's 61% stick threshold, and find my verify-screen numbers were llvmpipe-specific
Two things, and both are about a hidden parameter nobody was recording.

1. THE STICK THRESHOLD IS DECODED NOW, and it replaces an authored value.

The Decoder measured that the game digitises the left stick to four direction
bits at 61 % deflection, so it never sees a velocity. Gamepad.ENTER moves
0.5 -> 0.61. The 0.5 was never a chosen value: it was a FLOOR, because Godot's
`ui_*` action deadzone is 0.50 and the latch must not arm below it. Between 0.50
and 0.61 Godot reports a direction the real game does not, and at 0.5 this port
stepped there.

The mechanism also corroborates the human's latch fix rather than merely
agreeing with it: a control that digitises to bits cannot express a rate, so
"one step per deflection" is what the hardware layer CAN produce.

⚠️ The 0.11 hysteresis gap stays AUTHORED -- nothing says the game has
hysteresis at all. And a human chose 0.5, so this changes feel: revert the one
constant if 0.61 reads as needing too much push.

🔴 AND THE CONTROL CAUGHT MY FIRST ATTEMPT AT ASSERTING IT. I added the new
device-level row as subject "latch", and `verify-input --control` failed
immediately with "a check did not invert -- it is not testing what it claims to
test". It was right: removing the latch does not remove the THRESHOLD, the
unlatched path tests `>= Gamepad.ENTER` too, so 0.55 counts 0 either way and the
row could never invert. It is a NEGATIVE, and its positive control is the 0.70
row on the same shape. Reclassified.

That also exposed a smaller thing: ok()'s negative branch HARDCODED "positive
control is the stick row", so a second negative would have borrowed someone
else's green line. It now takes the control's name, defaulting to the original
text so the d-pad row is unchanged.

 I never consumed the pad bit table they have just corrected -- checked by grep
over port/, authored/ and tools/port/, not remembered.

2. MY verify-screen NUMBERS WERE llvmpipe-SPECIFIC, and the prediction failed.

Pre-registered: both renderers blend in encoded 8-bit space, so the diffs should
be identical or within 1 level on the GPU. They are not -- every mean rose 3-35 %:
title 0.4431 -> 0.5936, main_menu 3.9363 -> 4.1449, extras 6.7422 -> 6.9757,
title_jp 2.7715 -> 2.9448, main_menu_jp 0.7885 -> 1.0157, extras_jp 0.6592 ->
0.8906, build_12/15 0.0368 -> 0.0454.

But the MAXIMA are unchanged -- 41, 97, 113, 233, 17 identical, 26 -> 27 on one
row. That is a rounding population growing, not content moving: two rasterisers
round the last bit of a blend differently while the elements that genuinely
differ do not move.

Survives: the additive diagnosis, because it rests on an ORDERING and the
ordering holds (9 elements > 5 > 0); the pgloading_loop5 localisation; the
build_00/01 agreement; the derived allowance, same four failing rows.

Does not, and is now labelled: the histogram (53 % within 1 level, 16 844 over
40); every absolute mean; and the RMSE-vs-capture pair 3151.96 / 3769.61 -- that
ORDERING claim is not re-derived on the GPU and is not claimed until it is.

The rule this earns: a renderer comparison carries its RASTERISER as a hidden
parameter. Nothing here recorded which one produced a diff, and for months there
was only one so it never mattered. Same discipline TEMPORAL-VERIFICATION already
demands for capture rate, applied to what rasterises rather than what clocks.

Not settled: H1's repeat half; H6's +0x04 exposure; the four red verify-screen
rows; whether the port is still nearer the capture than the reference on the GPU.

ba3f490c67 port: P7's gate has an artifact, and the GPU kills my finding-4 candidate outright
Three things this iteration, and the middle one is the human's doing.

P7 -- GATE MET, with an artifact. The path had been wired for some time
(then_video S00A, skipped_chain, after_video -> title, and S00A.ogv in the
export) and NOBODY HAD RUN IT. A milestone is done when its artifact exists, not
when the wiring reads correctly.

Pre-registered: unskipped, S00A is 93.78 s of media, so it should end on its own
at ~94 s and hand off to title. Measured: video ended at 94.13 s -- +0.35 s,
0.4 % -- then -> title, plate raised, script complete at 96.83 s. Both
predictions held. docs/port/p7-gate.md.

And it genuinely decodes, checked because "ends at the right time" does not prove
it: 45 frames in a 2.03 s window, 244 in an 18.91 s one. Scales with the window,
sub-linearly, at the software fill ceiling -- those two runs predate the GPU. The
counts are upper bounds and the port says so itself.

Free corroboration of the fill-rate finding, from a direction it was not designed
for: the unskipped run reports main_menu at 60.3 fps for 94 s, because the screen
never changes during a movie. Same process, same container, same screen: 60.3 fps
with one full-screen video texture on top, 9.7 fps drawing the menu's five
additive full-screen quads.

 THE FINDING-4 FRAME-RATE CANDIDATE IS DEAD, tested rather than argued away.
The human activated a hardware GPU in both containers; Godot takes it with no
change on our side (NVIDIA GTX 1070 Ti, Vulkan 1.4.312, Forward+):

  publisher_logo   17.3-25.0 -> 69.4 fps
  developer_logos  16.7-22.8 -> 69.1
  title            12.7-17.2 -> 61.1
  main_menu              9.7 -> 59.6

Pre-registered that 5-7 full-screen textured quads at 720p is trivial for that
card and the fade would get its full 45 steps. At 69 fps the 45-unit build-in
gets 52 drawn steps and the companion glow's 15-unit rise gets 17 -- MORE frames
than declared units, so every declared alpha is drawn and the quantisation is
absent rather than reduced.

So every candidate for finding 4 is now dead: keyframes vindicated against the
vertex stream, companion quads drawn, blend space matching, settled pose at
0.01 %, no post-process pass, and the frame rate drawing every declared step. The
port has nothing left that is KNOWN to be wrong about the splashes -- which is a
statement about our knowledge, not about the port. The human saw something and
nothing we can measure reproduces it. The next play-test is now the
highest-value thing on this focus, and the rate line will say 60-something.

One figure did not improve: main_menu's worst gap is 117 ms on the GPU against
150 ms on llvmpipe, essentially unchanged while the mean improved 6x. A hitch
that survives a 6x fill speed-up is not fill. Likely first-frame cost, STATED AS
UNTESTED, recorded rather than chased.

check-all now asserts the display before any Godot step. Xvfb does not survive a
container restart and LEAVES ITS SOCKET BEHIND, so Godot reports "X11 Display is
not available", falls back to Wayland, fails that too, and exits non-zero -- and
every Godot-backed step would have gone red for that one reason. Cost me one run
before I noticed. Checked with xdpyinfo rather than by looking for the socket,
because the stale socket is what makes it confusing.

Also recorded from the P7 run, neither chased: Godot reports 4 leaked ObjectDB
instances at exit on that path, and the menu bed keeps playing under the movie
(already an open ask -- does the menu music duck?).

Not settled: the 117 ms menu hitch; H6's +0x04 exposure; H1 (with the Decoder);
the four red verify-screen rows; and what the human actually saw.

4be90c2805 port: the frame rate is llvmpipe, not our draw path -- and my finding-4 candidate is downgraded
Last iteration left "is 9.7 fps llvmpipe or something in our draw path" open
after publishing a candidate cause off it. That is not a question to leave open,
so this iteration is the control.

Pre-registered: if the rasteriser is the limit, a near-empty scene in the same
container also runs at 10-25 fps; if our draw path is, it runs far faster, take
>100 fps as the discriminator.

  empty  161.6 fps

The engine loop, viewport and present path are not the limit, by 16x over the
menu.

🔴 AND MY FIRST CONTROL WAS NOT A CONTROL. Its fill modes drew UNTEXTURED rects
while every element the port draws is a texture, so it bounded nothing -- and it
showed: the splashes were achieving ~21 Mpx/s against that control's ~50, which
read as the port being mysteriously slow and was the control being mysteriously
fast. With a matched textured mode:

  empty 161.6 | fill3 31.5 | tex3 23.9 | fill7 12.7 | tex7 11.2

and every port screen lands inside the bracket, ordered by large-quad count:
publisher (1 quad) 17.3-25.0 ~ tex3; developer (1) 16.7-22.8 ~ tex3; title (6)
12.7-17.2 between; main_menu (5) 9.7 ~ tex7's 11.2. The port draws large
textured alpha quads on a software rasteriser at exactly the rate a software
rasteriser draws them.

⚠️ The control's own spread is 1.75x between runs (fill3 measured 18.0 once and
31.5 once), so the absolute figures are noise-dominated and only the ORDERING and
the BRACKET are load-invariant. That is what the conclusion rests on --
TEMPORAL-VERIFICATION §3, prefer the quantities with no phase.

🔴 SO MY OWN CANDIDATE FOR FINDING 4 IS DOWNGRADED, AND THIS SAYS SO PLAINLY.
Last iteration called the frame rate "the first candidate for finding 4 that is
not already dead". The quantisation argument still holds -- a fade drawn in four
steps is not a fade drawn in fifteen -- but it only bites at these rates, and
these rates are a property of software rasterisation in this container. Five to
seven full-screen quads at 720p is nothing to a GPU. Unless the human ran the
port software-rendered, this is not what they saw, and EVERY candidate for
finding 4 is now dead or near-dead.

Written as a dead end rather than left standing as a lead. Leaving a
plausible-sounding cause up after its own control has undercut it is exactly how
"close but not right" got explained four different wrong ways. The one thing that
would revive it costs the human nothing: the rate line prints on every boot now,
so their next run answers it.

What the port does NOT need, established rather than assumed: no draw-path
optimisation (161.6 fps empty, screens on the fill curve where their quad counts
put them), no texture caching (already at load_screen), no max_fps or vsync
change (would not raise the rate here, and is a presentation decision not a
defect).

Not settled: what rate the human's machine manages -- now the only open half of a
candidate I have otherwise talked myself out of; H6's +0x04 exposure; H1 (with
the Decoder); the four red verify-screen rows.

   sylpheed-formats` never reaches the wrapper. Adding `-e CARGO_BUILD_JOBS` to
   the launcher did not help either: the entrypoint recomputes and exports over
   it unconditionally. An explicit value now wins, and says so in the log.

3. THE MEMORY CONSTANT WAS WRONG. `mem_gib * 2 / 3` assumes ~1.5 GB per job;
   release rustc on this workspace needs ~2 GB, and 4 jobs in 6 GB is what died.
   Divisor is now 2.

4. `--continue` CANNOT RESUME AN ABRUPT DEATH, which is the only kind we get.
   It resolves through ~/.claude.json's per-project `history`/`lastSessionId`,
   and MEASURED mid-session both are None -- they are written at a graceful
   shutdown. A killed container never writes them, so `--continue` answered
   "No conversation found to continue" with 33 MB of transcripts in the volume
   beside it. Persisting .claude.json did not help, because the fields were
   never populated in the first place; that attempt is removed rather than left
   in looking useful.

   The TRANSCRIPTS are durable and named by session id, so the entrypoint reads
   the id off the newest one for its cwd and passes `--resume <id>`. Verified
   on both agents: each reattached to its exact prior session and appended to
   the same file rather than opening a new one.

The /loop prompt is still passed alongside `--resume`, so the loop is RE-ARMED
rather than merely restored -- a resumed conversation with no wake-up scheduled
answers once and stops, which looks like resuming and is not.

Restarting into the same death is guarded at the other end: a start less than
120 s after the previous one begins FRESH instead of continuing back into
whatever killed it. That fired correctly during this work.

On resume the agent is told it was restarted, that its in-progress work is
uncommitted in the tree, that any build or capture it had running did not
finish and its absence is not a result, and which wrapper to prefer over a raw
release build.

170d255e82 port: the port never reported its own frame rate, and the menu draws at 9.7 fps
TEMPORAL-VERIFICATION §1 requires every instrument to state its achieved rate
against its requested one. That has been applied to --film (which I fixed for
exactly this), to the Decoder's harnesses and to the oracle. It had never once
been applied to the thing being shipped. The port had no idea what rate it drew
at and no way to say.

It matters now because the splashes are the focus and the open complaint is that
ours is LESS PRONOUNCED than the game's. A fade drawn in 45 frames and the same
fade drawn in 12 are different animations, and nothing here could tell them
apart.

boot.gd now counts frames per screen and reports at every boot transition, at the
end of the boot, and at every menu arrival. `worst gap` sits beside the mean
because a hitch is what reads as wrong and a mean hides one by construction.

Measured in this container, three boots:

  publisher_logo   17.3 / 19.6 / 25.0 fps    worst gap 100-115 ms
  developer_logos  16.7 / 21.9 / 22.8 fps    worst gap 103-138 ms
  title            17.2 / 14.2 / 12.7 fps    worst gap 150 ms, all three
  main_menu         9.7 fps                  worst gap 150 ms

🟡 A LIVE CANDIDATE FOR PLAY-TEST FINDING 4, and the first one that is not dead.
The timeline is delta-driven so durations stay correct at any rate; what changes
is how many alphas the fade is DRAWN at. At the measured rates the 45-unit
build-in gets 12-17 distinct alphas instead of 45, and the pre-blurred companion
glow -- the thing that IS the splash's blur -- rises over 15 units and is drawn
at FOUR TO SIX steps instead of fifteen.

⚠️ It is a candidate, not a cause: this is llvmpipe under Xvfb and not the
human's hardware. The point is that the line now prints on every boot, so the
next play-test answers it for free. Every other candidate for finding 4 is
already dead -- keyframes vindicated against the vertex stream, companion quads
drawn, blend space matching, settled pose at 0.01 % against the capture, no
post-process pass to add.

 And nothing published is invalidated, which was worth checking rather than
assuming: every timing result here comes from `_elapsed` (+= delta) or
`time_units` (the same sum scaled), so all are correct at any frame rate. The
splash dwells were measured across runs whose rates differed by 2x and agreed to
±0.03 s. Had the timeline been frame-counted, every number in this corpus would
have been wrong by a factor that changed between runs -- which is precisely the
failure the Decoder found in the emulator's rate and withdrew a finding over.

Two defects in the instrument itself, both caught and fixed before it was
trusted:
  - its first version printed "-9223372036854775808 requested".
    DisplayServer.screen_get_refresh_rate() returns a FLOAT and is -1.0 when the
    display cannot say, which Xvfb cannot, and %d underflows to INT64_MIN. It
    now names the cap or says `uncapped`.
  - it was BOOT-ONLY and said so nowhere -- `--menu` arrives through
    _menu_arrive, not _advance, so the mode a human spends time in reported
    nothing. That is the shape this port keeps finding in other people's work,
    and it lasted one measurement here.

Refutation attempt: I checked whether the port re-decodes PNGs per frame, which
would have been a real defect. It does not -- _load_textures caches at
load_screen. Hypothesis dead, cheaply, and recorded.

Not settled: what rate the human's machine manages; whether 9.7 fps on the menu
is llvmpipe or something in our draw path; H6's +0x04 exposure; H1 (the Decoder
is taking it this iteration).

977965e92d port: the splash rate is withdrawn, and timing the shipping boot caught a why describing code we do not have
H7 closed: the Decoder withdrew the per-GamePart rate the same day (1e7343e --
"it was the emulator's frame rate") and struck the section carrying it. The port
never moved, so nothing has to be undone. The refutation is kept because its
shape is reusable: a duration measured in emulator frames is the emulator's rate,
not the game's, and the tell was that it made a part outlast its whole.

That leaves the splashes with the rate at 60 unchallenged, the keyframes
vindicated against the vertex stream (worst error one alpha level in 255, no
renderer in the chain) and verify-capture at 0.01 % on both. So the one thing
nobody had checked was the REAL-TIME boot path -- our own timing end to end,
rather than a frozen pose or a model.

Pre-registered: at 60 units/s, publisher holds 255 + 9 = 264 units = 4.400 s and
developer 210 + 9 = 219 units = 3.650 s, the figures authored/timing.json states
the port emits. Accept +/-0.10 s. Three boots, no film competing with the
renderer:

  publisher   4.28 / 4.26 / 4.27   mean 4.270 s   declared 4.250   residual +1.2 u
  developer   3.50 / 3.57 / 3.51   mean 3.527 s   declared 3.500   residual +1.6 u

THE PREDICTION FAILED BY 0.13 s ON BOTH, AND THE PORT WAS RIGHT.

authored/timing.json sets black_hold_units = 0, deliberately, with its own
argument attached: a uniform black hold is positively EXCLUDED -- the same origin
gives different values to different destinations -- so only an ordered-pair key
survives and nothing may be authored until one is measured. There is therefore no
9-unit hold to add, and the port has never added one.

Two places said it did:
  authored/timing.json dwell_why -- "The port emits 4.400 s and 3.650 s -- each
    declared value plus the 9-unit black hold, exactly. So the pacing was right
    all along and nothing changes in the code."
  port/scripts/boot.gd, the _advance block -- the same sentence.

The `why` asserted a behaviour the SAME FILE refuses three keys below it, and the
code comment repeated it. Both corrected in place, with the measurement. No
behaviour changed: the claim was wrong, not the code, and the port has been
shipping 4.270 / 3.527 since P3.

⚠️ It does NOT show a hold does not belong there. Against the corpus means (4.42
and 3.46) neither figure dominates -- the port is 3.4 % short on the publisher
and 2.0 % long on the developer, where the claim would be 0.5 % short and 5.5 %
long. black_hold_why's ordered-pair ask is untouched.

⚠️ And it is a PATTERN, not an incident: this is the third `why` in this corpus
describing behaviour the code does not have, after exit_ramp_units and the dwell
slot that "was read NOWHERE for eight milestones". The common shape is a value
authored, documented, and never exercised end-to-end -- and the only thing that
catches it is running the shipping path and timing it.

Refutation attempts: the hit is against my own files again, found by predicting
my own behaviour and being wrong. The Decoder's keyframe vindication survived --
it is what makes 60 the only remaining variable on the splashes, and 60 now has
three cold boots plus three of my own runs agreeing with the declared groups.

Not settled: whether a black hold belongs between screens at all (needs an
ordered-pair measurement); H6's +0x04 exposure; H1 (key repeat).

94c38cb384 port: refuse the splash rate -- a 160-unit hold cannot outlast the 210-unit group containing it
The Decoder proposes a per-screen rate: ~57 units/s for the title, ~35-40 for the
splashes, on the ground that a splash at 60 runs 1.5-1.7x too fast. That would be
a timeline cause for the human's finding 4, so it matters. THE PORT DID NOT MOVE,
and this is why.

The 160-unit hold is identifiable: exactly one interval in either splash is 160
units, the DEVELOPER splash's a=255 plateau at t=30..190, inside its declared
group t=0..210. So:

  the 160-unit hold          measured 4.514 guest s   (1 run)  -> 35.4 units/s
  the 210-unit group AROUND IT  measured 3.37/3.50/3.51 s (3 cold boots) -> 60.7

A sub-interval cannot outlast the interval containing it. That is not two methods
disagreeing about a rate, it is arithmetic, and one of the two is wrong.

Both dwell measurements corroborate ~60 on exactly the two screens now put at
35-39: publisher 255 units in 4.30/4.60/4.37 = 57.7, developer 210 units in
3.37/3.50/3.51 = 60.7, the developer agreeing with its declared value to 1.1 %
and two of its runs to 0.3 %. At 35.4 the declared groups would run 5.93 s and
7.20 s -- each splash ~70 % longer than three cold boots measured it.

The one escape route is named rather than dismissed: the new figure is in GUEST
seconds and the corpus in wall-clock. The known gap between those is Canary at
~28.1 fps against 30, which is 6 % and the wrong direction to close 1.7x. It is
their instrument and their clock, so it is asked (H7), not ruled out.

⚠️ The STRUCTURAL claim may still be right -- one rate covering every screen is
what is under challenge, and the title's 56.8 does sit ~5 % off the splashes'
58-61. If a per-screen rate is real the port wants the MECHANISM, a field or a
GamePart constant, not two authored numbers. That is their next item. Recorded in
authored/timing.json so the next iteration does not quietly adopt it, with an
explicit instruction not to split the difference: averaging two measurements that
cannot both be true is not a third measurement.

Also this iteration:

H6 -- answered in principle, blocked in practice. They are right that the blend
is a decoded disc field (T8aD +0x04 bit 0x02) and that deriving beats
transcribing, which would delete an authored entry. But sylpheed-formats does not
EXPOSE +0x04 -- Element surfaces kind (+40), parent (+32), pivot, keyframes,
focus_link -- and sylpheed-export consumes formats by git TAG, not workspace
path, so I cannot reach the parser. Asked: surface the word and tag it.

🔴 And a negative worth having, since it is the obvious thing to try: kind_raw in
this export is NOT that field. Its bit 0x2 against the additive map over four
screens is ANTI-correlated -- 0 of 14 mapped elements have it set and 9 unmapped
ones do. Anyone reaching for `kind_raw & 2` gets the additive set exactly
inverted.

H5 -- closed. My shared-element hypothesis is refuted: build_12 and build_15 have
identical declaration bodies, so identical statistics are one fact. The
pgloading_loop5 localisation stands and is the better answer.

 And the good news, recorded where the splash work lives: "the declared keyframe
timeline reproduces the captured splash" settles in favour of the timeline -- 50
captured alphas, worst error one level in 255, no renderer in the chain. The
port's splash keyframes were never the defect. Which leaves the RATE as the
remaining candidate for what the human saw, and the rate is what this commit
declines to change.

Not settled: which of the two splash measurements survives; where a per-screen
rate would come from; the +0x04 exposure; H1 (key repeat).

0a9bf4e16a port: H5 localises to one element, and the rotation rule that explained 14 of 16 is refuted
check-all's four remaining red rows. What I established, and two hypotheses that
died on the way -- the second is the one worth reading.

 build_12 / build_15 are ONE ELEMENT. All 951 differing pixels lie inside
pgloading_loop5 (pgloading_ring.png, 333x276 at [1,444]) and the diff's own bbox
x 69..301 y 478..710 sits entirely within it. That also answers, with no rule at
all, why build_00 and build_01 AGREE: the port's own draw log says they draw 7
elements to build_12's 10, and pgloading_loop5 is one of the three they never
draw. The loading screens that agree are the ones that never draw the element
the disagreement is in.

🔴 REFUTED, and it looked strong. ui_layout.rs:86 states in its own words that
"rotation_deg is decoded but NOT rendered", and the port does render it. A
census over all sixteen exported screens gave: every screen with a non-zero rest
rotation DIFFERS, every screen without agrees -- 6 of 6 both ways, including
both legacy rows. Widening it to any rotating element (rest rotation OR a
two-keyframe 360 spinner at any depth) breaks it: build_00 and build_01 carry
two spinners each, the port draws both, and they agree with the reference.

A rule that holds on 14 of 16 and fails on the two cases nobody had looked at is
a rule fitted to the rows it was built from. Recorded rather than deleted,
because the ui_layout.rs:86 comment is exactly what the next reader will find.

🟡 main_menu_jp / extras_jp carry the same sweep leaves -- ptloop01/pteff03 at
rot 30, ptloop02/pteff03a at rot -45 -- whose phase residual is the reason
already named for `title`, and their means (0.79, 0.66) sit with title's 0.44
rather than their EN twins' 3.94 and 6.74. Consistent with, not established:
nobody has isolated those leaves on those screens.

🔴 And an asymmetry this exposed, now DECLARED rather than left silent.
main_menu_jp contains exactly the six elements main_menu marks additive, and
extras_jp all nine of extras'. The map is keyed by screen name and the Decoder's
RB_BLENDCONTROL0 log was taken on the ENGLISH screens, so the port draws them
additive on EN and alpha-over on JP -- asserting by omission that the JP build
blends differently, which is the LESS likely possibility.

Both options assert something unmeasured; only one of them was visible. The map
is NOT extended (that would extrapolate a measurement onto a build nobody drove
to) and the claim is instead written into authored/rendering.json's
additive_elements_why, plus a low-priority ask H6 that says out loud it may not
be worth a boot -- MISSION §7 puts JP out of scope and it costs two rows.

check-all stays red on the same four. Nothing was excused.

Not settled: why the two renderers disagree on pgloading_loop5 specifically; the
JP blend question; H1 (key repeat); whether the splashes tick at the title's rate.

26cf6ecac5 port: H3 closes with every named cause dead, and the verify-screen rows are ADDITIVE, not gamma
Three answers landed from the Decoder in one iteration and two of them refuted
things -- one theirs, one mine.

H3 -- CLOSED, and deliberately not closed green. The rate is measured at 56.8
units per guest second (control 1.15 %, two elements agreeing at one clock).
30 and 120 are both excluded. At 56.8 the plate's t=236 lands at 4.15 s against
this port's 3.93 s, so the port is fractionally EARLY. With rest.t, the clock
origin and the anchor already eliminated, ALL FOUR named causes are now dead and
the human's observation is unattributed. Written down that way rather than
letting H3 go quiet: the strongest remaining candidate is that A was unbound on
the play-test build, so that human could not skip the 137 s intro, and the run
they judged is not the run any of these measurements describes.

`units = 2 x frames` is dead as a route -- the same animation takes 21 labels in
one capture and 33 in another. Audited: this port never used it. boot.gd
integrates `delta * units_per_second`, so the retirement cost authored/timing.json
a JUSTIFICATION and not a behaviour, and I have recorded which leg died and
which survived. The surviving leg has no frames in the chain: 12 declared units
against a 0.14-0.30 s measured black plateau = 40-86 units/s, which excludes 120
on its own. 60 is KEPT -- 56.8 is 5.6 % away against ~5 % quantisation.

H4 -- ANSWERED, and MY PREMISE WAS WRONG. I reported the verify-screen rows as a
blend-SPACE divergence. The transfer curve I built for that was a mean per
reference-value bucket over a BIMODAL population -- 53 % of pixels within 1 level
and 16 844 differing by 40+ -- and the gamma shape was an artefact of the
binning. A mean over a mixed population is not a transfer function.

All three renderers blend in the encoded space:
  game       k_8_8_8_8 on 2402/2402 and 33779/33791 draws, _GAMMA zero times
  Godot      measured with a pre-registered control -- alphas 64/128/192 render
             64/128/192 exactly; linear-then-re-encode excluded by 33-74 levels
  reference  integer math straight on 8-bit values, no linearisation

The real cause is ADDITIVE. The port draws 5 elements additive on main_menu and
9 on extras, transcribed from the Decoder's per-draw RB_BLENDCONTROL0 log off the
running game; ui_layout.rs has exactly two blend sites, both alpha-over, and line
1169 records that it tried additive and refuted it from its own composite
metrics. The two renderers disagree on purpose, and the disagreement tracks the
set size: 9 -> 6.74, 5 -> 3.94, 0 -> ~0.7. That ordering was not fitted; the
additive map predates this comparison.

check-all: the allowance is now DERIVED from authored/rendering.json's additive
set plus the two legacy rows, instead of a literal list. A screen is excused
BECAUSE it has additive elements the reference cannot draw; one that differs
without them still fails, which a list could not express. Verified against the
last run's set: main_menu and extras pass, main_menu_jp, extras_jp, build_12 and
build_15 still FAIL. check-all stays red on those four and they are H5 -- not
diagnosed, not excused. build_12 and build_15 report byte-identical statistics,
which points at one shared element rather than two coincidences.

Refutation attempts: the hit this iteration is against my own page again -- the
blend-space diagnosis, killed by a control I ran on my own renderer. The
Decoder's encoded-space finding and their 56.8 both survived the only checks I
could make: my control reproduces their space independently, and their rate is
consistent with authored/timing.json's frame-free leg.

Not settled: H5's four rows; whether the splashes tick at the title's rate (they
are a different GamePart); H1 (key repeat); what the human actually saw.

da7864e499 port: both of my H3 conclusions were wrong, and check-all stays red on a sixth-screen divergence
The Decoder answered H3 in both halves (a482d9a, against a pre-registration
committed before they read the capture) and refuted two things I published an
hour earlier. Both are struck in place, not deleted.

1. units/frame is 2, not the 5 I inferred. Three consecutive gap-free steps of
   exactly 23 on ptbtn00's own ramp; 255*2/22 = 23.18. My 4.4-frame prediction
   is excluded by more than 2x.

   My derivation was sound arithmetic on two unsound premises, both mine to
   have used:
     - an alpha step is not a clock rate. dA/frame = 255*(units/frame)/T, so
       elements with different declared T show different steps at ONE clock.
       Splash quads step 34 with T=15; the plate steps 23 with T=22.
     - my "onsets" were first submissions, and on splash A both quads are
       already at a=85 when first submitted -- biased late, and by a different
       amount per element because the bias scales with T.
   The three intervals agreed with each other because they SHARED the bias.
   Three measurements with a common error are one measurement. That is the
   shape I should have checked for and did not.

2. My claim that the t=160 anchor collapses `clock: "shared"` is WITHDRAWN. The
   anchor is indeed t=160 -- ptcopyright, calibrating to t~168-176 -- but I
   falsified the model using the 2.135 s figure, which is the one number the
   same capture puts in dispute. Falsifying a model with the quantity that is
   itself under dispute is the error. Against the new capture's own labels the
   declared 54 and 76 units reconstruct at 44 and 66 -- short by 13-19 % in the
   same direction, with empty labels a named candidate for the residual.
   `clock: "shared"` stands, and the port keeps it.

Still open and now the only thing left on H3: units/second = 2 x guest fps, and
whether the guest is 30 Hz or 60 Hz is unestablished. 2x60 = 120 units/s puts
the plate at 1.97 s instead of 3.93 s, which is the size of what the human
reported. The Decoder asked me not to move off 60 on their account yet; I have
not.

Separately -- check-all is RED and stays red. verify-screen newly DIFFERS on six
screens outside its allowed set (main_menu, extras, main_menu_jp, extras_jp,
build_12, build_15). Measured, not diagnosed:

  * not this iteration's doing, and excluded structurally rather than by a
    passing test: sprites are read as bytes and built with
    Image.load_png_from_buffer, so they never enter Godot's import pipeline and
    the new `--import` step has no path to the drawn pixels;
  * the difference is FULL-FRAME, exactly zero on unblended pixels (18 081 of
    them agree to a hundredth of a level at ref 199/204/255) and gamma-shaped on
    every blended one. That is a blend-SPACE divergence, not moved content;
  * scored against live-main-menu.png the port is 16 % closer than the reference
    (RMSE 3152 vs 3770) -- an ordering only, since both sides carry this
    script's --pose=rest contamination, which has produced a false finding here
    before.

Not widened. This allowance has twice been broadened with a reason that turned
out false, and "I measured it but cannot say which renderer is right" is not a
reason. New ask H4: what colour SPACE is the blend evaluated in -- the Decoder
has the equation from shader ucode, not the space.

Refutation attempts: both of this iteration's hits are against my own page from
last iteration. The Decoder's units/frame law and their anchor measurement both
survived the only check I could make of them -- their steps reproduce this
export's declared T on two screens at one clock.

Not settled: guest fps; which renderer's blend space is right; H1 (key repeat).

6eccfa84d8 port: the plate's lateness is the unit, not our clock -- and the splash blur is an asset we already draw
H3, the PRESS (A) plate. Established which half it is, as the brief asked, and
the answer moved once during the iteration -- both readings are recorded because
the first one was confident and wrong.

Eliminated, ours:

  rest.t      not in the causal path. The plate's ARRIVAL is a declared keyframe
              (transparent to t=214, opaque at t=236); rest.t=236 only picks
              where `holding` parks it, and 236 is that ramp's own peak.
  clock origin  the two builds share one clock exactly -- 85 of 85 filmed title
              frames have view_units == overlay_units to 3 dp.

NOT eliminated, the Decoder's: the unit->seconds constant. I first ruled it out
"by sign" using the emulator's 28.1 fps presentation rate. That conflates a
wall-clock conversion with units-per-game-frame; the correction is written down
rather than edited away. The Decoder's splash draw capture (3cc1b51) then gave
an independent handle on it, from a screen with nothing to do with the plate:
three intervals of the publisher splash all read 5 units per guest frame against
the declared 2. At 30 fps the plate would land at 1.57 s rather than 3.93 s --
this port ~2.4 s late, the right magnitude for what the human saw. It collides
with title-plate-delay-measured.md (~55 units/s) by a factor of 2.7. Both are
oracle measurements; asked in BLOCKED.md H3, not picked between.

Finding 4, the splash blur. The Decoder found no post-process pass; the human
says the logos go blurred -> sharp in about a second. Those resolve each other:
every logo ships a pre-blurred copy ~21x20 px larger and concentric, drawn alone
first and crossfaded out as the sharp logo fades in.

  🔴 So "the port applies no blur at all" -- in BLOCKED.md H2 and in the
  play-test -- is FALSE, and it came from our side. The port draws all seven
  quads of the developer splash, companions included, and always has. Shown by a
  frozen sweep 3 units a step: companions alone at u=3..15, all seven at
  u=18..42, sharp only from u=45.

The instrument had to be fixed before any of this counted. `--film` scheduled
frame n for n*interval and reported nothing; one 1280x720 save_png costs ~0.24 s
under llvmpipe, so a request for 0.05 s delivered 247 frames in 60 s where 1200
were asked for -- an achieved 4.1 fps against a requested 20 -- and the deficit
accumulated silently into the frame index. It now writes <film>_frames.tsv with
the second each frame was ACTUALLY taken at, and prints achieved against
requested. The schedule is deliberately not rebased onto _elapsed: catching up
would hide the shortfall.

check-all now reimports the Godot project first. `port/.godot/` is gitignored, so
merging a commit that adds a `class_name` leaves a stale class cache and the
whole project fails to parse -- which is exactly what merging the human's
gamepad.gd did in this container.

Refutation attempts, four:
  survived  the title's settle window [160, 236] -- our exporter still computes
            [160, 236, 198] under the corrected record layout
  survived  the Decoder's Q0/Q7 quad mapping -- this export's declared rects
            reproduce the guest's vertex stream to ~2 px and ~4 px
  refuted   "ptlogo1 rests at t=251 and stops moving at t=42" -- rest.t is now
            42. The record-layout fix repaired the very element that was the
            headline evidence for rest.t != settle. The conclusion survives on
            other elements; the example does not
  refuted   ours: "ptbtn00 reaches a=255 at t=238" (it is 236, so 118 units not
            120) and "pteff00 is 7 % opaque at 243" (it is 0 %; that quad clears
            by t=16 and 261..269 is the fade-OUT, not a fade-in)

Not settled: which of the two oracle rates is right; whether the t=118 or the
t=160 anchor is what the glyph counter saw; whether the game holds the blurred
companion longer than we do.

Both are pushed. The decoder's carries the R1 register reclassification and
tools/stale-instrument; the port's carries the two input fixes, verify-input
and BLOCKED H1-H3. Each branches from that agent's own tip, so it is a
fast-forward on the line they are already on -- and the port must merge before
touching input or it will re-derive a fix that is already asserted.

aad3fb382e agents: the splashes exactly, and stop photographing a moving thing

A human played the port on real hardware for the first time (2026-09-01) and
found four things. Two were port defects, fixed. Two are open and are now both
agents' focus: the PRESS (A) plate arrives late, and the splash fade/blur is
weaker than the game's.

Their verdict on method is the reason this is a brief change and not a ticket:

  "the agents were essentially guessing and trying to copy what one would see,
   but while they did get close it still is not quite right"

Close-but-not-right is the signature of reproducing APPEARANCE instead of
deriving MECHANISM. So the Decoder's focus block asks, in order: is there a
post-process pass at all, what is it, where do its parameters come from -- and
only then what curve. Both routes, dynamic (GPU state, shader constants, render
targets; add logging to Canary, it is theirs read-write) and static (.pe, the
DB, the paks), with each fact labelled by which produced it.

TEMPORAL-VERIFICATION.md is the other half, and it generalises past the
splashes. We have been photographing the game at time t, and t is never the
same twice: emulator speed varies with host load, Canary presents at ~28.1 fps,
the capture path costs a variable 0.1-10.8 s, and a long-lived x11grab stream
degrades and then freezes. The register already carries FOUR refutations of
exactly this shape. The replacement rule: record a film, not a photograph;
align by CONTENT, not by clock, and report the lag as a measurement rather than
minimising it away; prefer ordering, counts, durations and shape over any value
at a wall-clock instant; anchor on an event; report achieved fps against
requested fps.

Also into both briefs: the input set. The port had no joypad binding for (A) or
(B) and nobody noticed for a whole milestone, because --script sends
InputEventAction, which BYPASSES the input map -- so every check asserted the
code below the map and nothing about the map. The Decoder is asked to DECODE
the full set the game reads rather than discover it by pressing buttons; the
Port is told input is verified at the device level or not at all.

And both briefs now point at the R1 register reclassification, because two of
the ten re-opened entries land on this focus: "the declared keyframe timeline
reproduces the captured splash" is 🟡 our-reader, and the rest() pair is open
in BOTH directions -- while the two splashes are the only screens that reach
that fallback.

b70b638cb4 port: Ⓐ was never bound to the pad, and the stick is not an edge
Both found by a human playing the port on a real controller. Both were
invisible to every check this port has, for one reason:

  `--script` sends InputEventAction, which BYPASSES the input map.

So the harness asserted every line of code AFTER the map and nothing about the
map itself. Measured on this Godot, not remembered -- the remembered answer was
wrong:

  ui_accept   key:Enter, key:Kp Enter, key:Space     <- no joypad at all
  ui_cancel   key:Escape                             <- no joypad at all
  ui_up       key:Up, JOYBTN:11, JOYAXIS:1-          <- d-pad AND left stick
  ui_down     key:Down, JOYBTN:12, JOYAXIS:1+

Four actions worked on the pad and two did not, which presents as a broken
controller: navigation moved, Ⓐ skipped nothing and opened nothing. Godot
4.7.2 binds no joypad button to ui_accept or ui_cancel.

Gamepad.bind_missing() ADDS the two buttons to the built-in actions rather than
redefining them in project.godot, which would replace the built-ins wholesale
and drop the keyboard bindings silently.

Second defect, same blind spot: an InputEventAction is not an analog axis. The
left stick is bound to axis 1, and an axis is not an edge -- held at deflection
it emits an event per jitter, each reporting the action pressed. That was one
cursor step per jitter ("moves the cursor too fast"). The stick is now latched
to one step per deflection, with hysteresis so a stick resting near the
threshold does not chatter.

AUTHORED, and deliberately the conservative half: whether the game REPEATS a
held direction, and how fast, is an oracle question. One deflection one step
cannot run away and invents no rate. Logged as BLOCKED H1.

tools/port/verify-input asserts the map and the latch, with a control that
removes each check's OWN subject -- its first version inverted all nine
assertions when only two depended on the fixup, and reported seven correct
checks as broken. Three rows say plainly they are not controllable (they assert
Godot's own bindings) and one is a negative carrying a positive control (R4),
rather than faking an inversion for either.

Also logged BLOCKED H2, unguessed: the splash blur/fade-in is more pronounced
in the game than in the port. The port applies no blur at all. Noted there that
the two splashes are the only screens reaching the rest() plateau-less
fallback, which the R1 pass just re-opened in both directions.

c2cbb277bb retro: tick §7.1 -- the R1 register reclassification is done, and what it found
Done 2026-09-01 by the human on the Decoder's tip (branch
human/r1-register-reclassification): all 222 REFUTED.md entries carry an
⟨instrument⟩, ten moved  -> 🟡, R1 is standing text in PROTOCOL.md, and
tools/stale-instrument is the --stale query.

Flagged here because one of the ten is load-bearing for the port: rest()
decides the pose every plateau-less element is drawn at, and the question is
open in BOTH directions -- each leg runs through our renderer.

6b713e8d14 port: confirm the plate quad by size, and record a frame-spacing discrepancy I cannot close
Read the Decoder's existing title draw log from the ref. The additive quad carries
per-vertex alpha 68, 67, 56 across log frames 1, 2 and 4.

Identification confirmed independently and without using their attribution: the
quad is 537.6 x 75.6 px and ptbtn00f.png ships at 537 x 76.

Their free check on my ramp holds -- all three alphas are at or below my declared
peak of 80 and none equals a keyframe value, so the game interpolates rather than
steps. Two independent decodes agreeing.

The frame spacing does not fit. At HANDOFF Q1's 2 units per rendered frame my
falling segment predicts 68, 64.5, 57.6 against observed 68, 67, 56; at 0.5 units
it predicts 68, 67.2, 65.4. No constant rate fits both steps.

Three candidates I cannot separate: my ramp is wrong somewhere, the log's frame
numbering is captured rather than engine frames -- it skips from 2 to 4, so it is
demonstrably not dense -- or emulator pacing varies. The middle is most likely and
cheapest to check, and it is theirs.

It does not disturb the ramp's shape or ceiling, which the alphas confirm. It
disturbs only posing my renderer at their captured instant by stepping units, so
the vertex alpha stays the right readout and a frame index would have been wrong.

a68c8607c6 port: pre-register the plate composite test, and catch my own prediction being wrong
The Decoder's R2 note: alpha peaks at 80 of 255, so the composite difference is a
small signal either way and the expected magnitude should be set before the test.
Committed here before any capture exists.

Rendering the same pose at peak alpha under both composites: 25 015 px footprint,
mean |additive - alpha-over| 16.92 levels inside it, max 50, RMS over the whole
frame 3.746.

My first prediction was wrong and that is the useful part. The composites differ by
exactly alpha*bg, which with mean background 94.78 predicts 29.73 levels. Measured
16.92. The formula uses the keyframe alpha and ignores that the sprite carries its
own per-pixel alpha channel modulating it -- implied mean sprite alpha about
145/255. Caught only because the prediction was written down and disagreed with the
render.

The pre-registered test: additive is brighter than alpha-over at every footprint
pixel in one direction, so the discriminator is regional SIGN over 25 015 pixels,
not per-pixel magnitude. If the game is additive, rendering alpha-over must leave
the footprint about 17 levels darker than the capture relative to the surrounding
frame, and additive must leave no such regional bias. Neither bias refutes both and
points at the ramp or the pose instead.

Feasibility stated before asking for a run: as a whole-frame RMSE the difference is
3.746, below the title's own +/-5.56 capture-phase term, so verify-capture's
headline number could not settle this even at peak alpha. It is discriminable only
as a signed regional statistic.

8eda446228 port: the plate's ramp was already in my export, and the renderer reproduces it
The Decoder is paused and could not take the capture I asked for, and said the disc
half might not need them. It did not, and it did not need a new decode either: the
ramp is already in export/screens/title/press_start.json. ptbtn00f carries eight
keyframes on a 120-unit loop, alpha in the high byte of fade_argb, 0 -> 80 -> 0
with the peak held across t=35..50.

Two things follow with no oracle. The blind phase is confirmed from the disc rather
than inferred from rendering: alpha is exactly 0 at phase 0. And the renderer
applies the ramp faithfully -- rendered contribution against declared alpha across
six phases gives r = +0.9982, slope 0.4036 levels per alpha unit.

So when and how strongly the port draws the highlight is verified. Only the
composite is open, and the existing capture cannot settle it under either reading
of the clock: posed at t=237 the phase is 117 where alpha is about 0, and the
harness independently pins loop-phase 0 where alpha is exactly 0. Both agree, which
is worth stating because I did not have to assume which clock the record runs on.

The ask therefore narrows from "a mid-pulse instant" to a named window: one capture
anywhere in t mod 120 in [35, 50], where alpha holds at its peak of 80.

d45b23ebbe port: draw the plate's highlight additive, and find my harness poses it where it cannot be seen
blend-bit-vs-oracle.txt entry 2: ptbtn00 alpha-over, ptbtn00f ADDITIVE -- the
PRESS (A) plate and its own highlight, one bit apart. Entry 4, the whole title, is
alpha-over throughout including ptlogo_back2/ptlogo_back2eff, which independently
kills the "frame-shaped and mostly transparent means additive" rule I declined to
adopt.

Bands are now per DRAW OP rather than per paint-order entry: one band per element
cannot express base alpha-over with its own focus record additive.

The change reported zero three times and each zero had a different cause.

First, additive_elements was assigned to `view` in three places and to `overlay` in
none, and the plate is an overlay -- every other decoded rule on that page goes to
both.

Second, I then measured that the element is never drawn, suppressing its sprite at
six times across the cycle for 0 px every time, and was one commit from filing "the
port never draws the plate highlight" as a defect. That sweep was invalid: I varied
--time while passing --loop-phase=0 in every run, and --loop-phase pins exactly the
clock a looping record runs on. Six samples of one phase.

Third, swept properly, ptbtn00f contributes 0 px at phase 0 and 22-29k px at phases
20-100 -- and verify-capture's title_plate row poses at loop-phase 0. The row that
validates the plate is blind to the plate's pulse by construction. It correctly
reports 13.03 / 0.09 % unchanged while the fix moves 26 319 px at phase 20. Stated
in the tool next to the pose.

Not verified against the oracle: every title-plate capture we hold is at the blind
phase, so no capture here can confirm the port now draws it right. Asked.

9a8b43e7dd port: fix the runbook's unattended walk -- it never reached the submenu P5 rests on
RUNNING.md gave `--script=down,down,accept,cancel` as the unattended P5 walk. Two
downs from the opening item lands on TUTORIAL, whose destination this export does
not carry, so the example printed a not-carried message and returned to the title
without opening a submenu at all. EXTRAS is the fifth item and needs four.

The one submenu the milestone's gate rests on was the one the runbook's own command
did not reach, and it survived because the command completed successfully. Third
instance this session of "the run succeeded and the answer was wrong", after the
MIX-default material and the vertex dump that captured two of six quads -- and the
first one sitting in the document written for a human to follow.

Verified by running both paths. Also verified end to end this iteration, on the
real binary rather than from the document: cold boot reaches the title in 152.9 s
with the intro playing 142.2 s for 137.4 s of media (+3.5 %); wrap, the left/right
no-ops, EXTRAS opening on MISSION SELECT, B restoring the item you left, EXTRAS
resetting to its own first item on re-entry, and the focus surviving a title round
trip all behave as the table says.

05be7d19f7 retro: the agreed result, plus the cue-suppression matrix it came out of
Agreed retro with the Decoder at docs/agents/RETRO-2026-08-31-agreed.md; their own
review is at docs/agents/RETRO-2026-08-31.md on auto/frame-blend-draw-path.

Twelve rules, of which the ones neither of us had: a refutation whose instrument is
one of our renderers is not a refutation but "our renderer disagrees" (this cost
weeks, both ways); a negative must carry a positive control, which no "undecodable
with reach" page either of us has written ever did; and a disagreement is evidence
about the chain disc -> decode -> render -> capture, not about the link being
looked at.

The gap underneath our controls, stated: they verified capability, not
configuration. My additive material passed every control because they tested
whether the method detects a blend difference, not whether this run had blend_mode
set -- it was Godot's default MIX. Their vertex dump passed every control because
they tested the NDC conversion, not whether it captured all six quads.

Nothing applied to PROTOCOL.md. The register re-classification changes the file
both agents read to decide what not to try, and two agents agreeing is not the
right authority for that.

Also committing the work that was pending when the stop came: verify-menu-audio
now settles cue presence by suppression -- silence one cue's .ogg, re-record the
same walk, and require its own correlation to collapse. All three cues sound
(+0.158 / +0.637 / +0.526). The bed-only margin no longer renders a verdict: it
called `move` NOT FOUND on three runs at 0.109-0.131 while the cue was
demonstrably sounding, and across runs the same cue reads 0.131 and 0.158, so the
threshold was never a property of the cue.

The off-diagonal is reported as masking rather than asserted: silencing confirm
raises back by 0.468 because the game plays them 90 ms apart under a 0.15 s
template. An assertion there would fail forever on correct audio.

975d77f0b2 port: take the completed EXTRAS blend set, and record two refutations that land on me
EXTRAS whole-screen residual 1.97 -> 0.63; ptframe4 31.90 -> 1.14, pteff21/22/23
from 12-14 to under 0.8. The four elements I reported as in no draw were in a draw
all along -- the vertex dump was capped at two quads and the batch holds six, so
four were dropped with a well-formed line and no ellipsis. Same failure class as my
MIX-default material: the run completed, the output parsed, the answer was wrong.

Their pteff10 flag, tested by holding it alpha-over with everything else additive:
tone-corrected residual 0.630 additive against 1.704 alpha-over, but raw RMSE 12.91
against 9.98. They disagree because the port already renders +8.50 levels brighter
than the capture on this screen before any of this, so raw RMSE punishes added
light whether or not the light is right. Adopted on the measurement plus the
structural metric; extras raw-rmse went 11.43 -> 12.88 and that is stated, not
hidden. The differing region halved, 0.07 % -> 0.03 %.

Refuted, mine: "every decoration 0x0 and every button 0x3002" was a two-screen
generalisation I called a confirmation, one message after objecting to exactly that
move in their page. My own export held the counter-examples -- ptbtn00 is 0x73002
and my exporter calls it unknown rather than button; three title elements are
0x3000, button-shaped and not focusable. kind & 0x2 is the focusable flag.

Refuted, mine: the sweeps DO run on the main menu. Their log retains NDC and both
strips overlap the screen in every captured frame, stepping in opposite directions
with vertex alpha ramping. My phase sweep measured that the PORT'S sweeps make the
match worse, which is a statement about my rendering, not about the game. A
best-match argument for an absence cannot separate "not there" from "there and
drawn wrong", and I had that caveat written down and read past it.

Not flipped: the strips are additive with a ramping vertex alpha and the port has
neither on the leaf path, so enabling the loop today would be more correct in
behaviour and worse on screen. The ramp is asked for. What changed today is the
claim -- the port is wrong here and now says so.

49a6333166 port: free the canvas items I leaked, and refute the blend measurement's reach sentence
The RenderingServer rewrite leaked 5 CanvasItem RIDs per run -- exactly the number
of paint-order runs on the main menu. Items created through the server are not
owned by the node; a child Node2D would have been collected for me, and the reason
for not using one is the reason this had to be paid for. Freed in _exit_tree.

Nothing failed. verify-capture was green on every screen and the pictures were
right; the leak line sat next to "N ObjectDB instances were leaked at exit", which
BLOCKED.md records as engine-side and not ours after releasing every reference the
port owns moved the count not at all. A new leak line beside a known-benign one is
close to perfect camouflage. What distinguished it was the number: 5 is a count of
my bands.

Refutation, and it lands. ui-blend-mode-measured.md closes "every element on the
two screens the port ships is in the table except the two above and pteff10".
Checked against my export, counting the summary table's prose rows as coverage:
exactly right for main_menu, and on EXTRAS it misses four -- ptframe4, pteff21,
pteff22, pteff23. Five, not one.

They are not an arbitrary four. They are precisely the elements the port now
measures as the worst on that screen, ptframe4 at 16.19x the frame mean. Every
measured row still stands and the port has transcribed all of them; what is wrong
is the reach, and it is the difference between "one loose end" and the open ask in
BLOCKED.md, which now says so.

Secondary, offered as such: "every button" in the summary row is a class
generalisation in a document that warns its reader to take the table as per-element
facts. No button appears in the EXTRAS draw log at all. Very likely right, nothing
of mine depends on it.

0ca6d254f8 port: transcribe the sweeps' additive blend, and re-run my own menu-looping evidence with it
ui-blend-mode-measured.md names both rotated sweep strips additive in the same row
as the frames. Those are ptloop01/ptloop02 here, now in additive_elements for both
measured screens. It changes nothing visible: on the menus the port runs the leaf
group once and parks it off-screen, and suppressing both sprites at leaf-time 100,
200 and 300 changes 0 pixels each time. It is in the file because it is measured.

Refutation attempt on their identification, and it survives with a number of mine.
The automatic matcher reports "no match" for those two draws; they rest on one
control reproducing heights 1134 and 1303. Rendering the menu at a phase where the
sweeps are on screen and suppressing them gives a footprint 884 px wide against
their 889.6 -- 0.6 % apart, derived without using their number. The heights differ
as they should: my bbox is clipped by the screen, theirs is the full quad extent.

The blend was a confound in my own earlier evidence. loop_leaf_why scoped looping
to the title partly on a phase sweep of mine that drew the sweeps ALPHA-OVER, so
an on-screen sweep was composited wrongly and then scored against the capture. Re-
run with additive and looping enabled for the menu, through a scratch export root
so the repo was untouched: parked 0.0208 %, phase 150 on-screen 0.0851 % with the
sweeps painting 58 027 px, other on-screen phases 0.086-0.122 %.

The conclusion held and got stronger -- 3x with the wrong blend, 4-6x with the
right one -- so the scoping stays and the correction is what is recorded. Still one
capture, and best-match is still weak evidence for an absence.

And a reading of the new log that I did not make: it shows both sweeps SUBMITTED
on the main menu in every frame group, which is not evidence they animate there. A
quad parked off-screen at x=1521 is still a draw call. The log settles the blend
and not the visibility, and both questions arrived in the same artefact.

c453d8dade port: draw the measured additive blend -- main_menu 13.21 -> 10.67
The Decoder logged RB_BLENDCONTROL0 per draw in Canary on both screens.
0x01010101 is src=ONE dst=ONE, additive. That makes the blend a transcription
rather than my proposal, and they withdrew the "any blend you choose is authored"
instruction explicitly.

Their control is what licenses the change: one pixel shader, 0xE59B2B3DA4AA9008,
runs with BOTH blend states on the main menu -- 12 additive draws and 18
alpha-over. The frames and ptbase share a shader; only the blend register differs.

authored/rendering.json gains additive_elements per screen. Every id is a measured
draw and the reach is written beside it.

verify-capture: main_menu 13.21 -> 10.67 (0.06 % -> 0.02 %), extras 13.38 ->
11.43, main menu with ptbtn04 focused 13.82 -> 11.36. Per element, ptframe1
22.72 -> 4.17 and ptframe2 13.09 -> 3.32.

Neutrality control, free with the table: publisher_logo 2.17 and developer_logos
3.05 are unchanged to the digit. Those are the screens whose metric is absolute
and they carry no additive element, so the rewrite that routed every draw through
RenderingServer canvas items did not change the picture. The improvement is the
blend, not the plumbing.

RenderingServer rather than child Node2Ds because boot.gd calls view.queue_redraw()
from nine places and none reaches a child node -- bands would paint the previous
pose, which under --script=wait is a plausible wrong capture rather than an error.
Runs are recomputed per frame: the additive elements are consecutive on both
measured screens, and that is an accident of those two screens.

And the change first ran with the material left at its default MIX, moving
ptframe1 from 22.72 to 22.69. Nothing errored and a 0.03 move is a plausible
negative result. It was caught only because the measurement predicted a large move.

Not done: ptframe4 is now the worst element on EXTRAS at 16.19x the frame mean and
additive would plainly help it. It is not in the measured table, so it is not in
the file. Filed in BLOCKED.md with pteff21/22/23, which are also in no captured
draw.

Refuted, mine: "neither frame has a fully-opaque pixel" was true and was not the
discriminator -- pteff10 has max alpha 130, no opaque pixel, and measures nearly
exact. The direction survived; the reason for it did not.

0a054d681b port: discriminate the blend -- additive halves alpha-over's error on both frames
Last iteration could say the shortfall scales with the background but not which
curve. That is decidable with no RE: an element rendered over two different
backgrounds gives two equations in a and aC, and the mod tree supplies the second
background by suppressing pteff10/pteff12, which moves it by a mean of 26 levels.
No placement, no coordinate transform, no texture decode assumed.

The control is exact. Alpha-over rebuilt from the solved per-pixel a and aC
reproduces the port's own render at RMSE 0.0000 on both screens, so the recovered
values are right rather than a fit that lands nearby.

RMSE against the capture, ptframe1 / ptframe3:
  additive     34.305 / 28.948
  screen       50.052 / 50.368
  alpha-over   65.046 / 71.299   <- what the port does
  not drawn    90.916 / 109.801

Same ordering on both. The frame is certainly drawn in the capture, and additive
roughly halves the error of what the port currently does.

What it is not: additive still leaves 28.9-34.3, so none of the three reproduces
the capture. This ranks candidates, it does not identify the equation, and the
absolutes are inflated by mapping the capture through the fitted LUT inverse --
the ranking is fair because all four go through the same mapping.

Nothing adopted. The Decoder established no blend is on the disc for .t32, so any
choice is authored, and the mission says propose rather than take. The renderer is
unchanged.

Refutation attempt, recorded as surviving: their kind-0 claim checked against my
own exporter's independently decoded kind_raw. Every sprite decoration on both
screens is 0x0, frames included, every button 0x3002. Two independent decodes
agree, which is also what makes the blend question sharp -- the frames are declared
identically to ptbase and pteff05, which the port draws at 1.31x and 0.92x.

b6a4a079f9 port: generalise the frame finding, refute my own premultiplied-alpha hypothesis
tools/port/element-residual turns last iteration's one-off suppression into a tool:
pose a screen as verify-capture does, shadow each sprite with a transparent PNG,
rank elements by residual on the pixels they actually paint. Two controls, both
mandatory -- the metric's zero on identity, and a mod that shadows nothing must
move zero pixels, or a footprint is the harness rather than the element.

It generalises. Frames rank 1 and 2 on both screens with captures: ptframe1 9.47x
and ptframe2 5.46x on main_menu, ptframe3 14.23x and ptframe4 10.46x on extras,
all four body-dominated and all four negative. The sign splits, so it is not global
darkness: ptmsg +5.02, ptmsg2 +8.83, pttitle +7.88 and every button positive.

Refuted my own next hypothesis. Premultiplied alpha decoded as straight alpha
predicts error proportional to partial-alpha fraction; the frames are 6.7-7.3 %
partial and the most darkened, while pteff10 is 100 % partial and nearly exact.

What the frames are: neither has a single fully-opaque pixel, against ptbase's
99.1 %. For a wholly semi-transparent overlay the blend equation decides the
result, and alpha-over's shortfall against a background-scaling blend is a*bg. So
the shortfall should track the BACKGROUND, not the frame's own contribution.
Measured on render, frame-suppressed render and capture, needing no placement:
ptframe1 +0.772 vs +0.244, ptframe3 +0.797 vs +0.237.

Not adopting anything. The Decoder has established no blend mode is on the disc
for .t32 and both frames are kind 0, declared identically to elements drawn almost
exactly right, so any blend I pick is authored and that is not mine to take alone.
Recorded as an extension of their negative, not a challenge: the behaviour is real
and replicated, so if nothing in the data selects it, something in the code does --
the draw path they named as untaken.

BLOCKED.md updated: the ask is answered, as a negative.

cce31cb592 port: localise the menu residual to two frame elements by suppression, and refute my own hypothesis
The Decoder named the elements under my hot tiles and had to test both coordinate
readings, because design space and the comparison frame differ by the capture
transform. I did not need the transform: the port has a mod tree, so shadowing a
sprite with a transparent PNG and diffing my own two renders measures the
element's footprint directly, in the comparison frame, assuming no convention.

Ranked by residual density on each element's own visible pixels: ptframe1 22.72
(9.47x the frame mean), ptframe2 13.09, ptmsg 8.46, pteff12 4.98, ptbase 3.34.

That refutes the hypothesis I came in with. I predicted the EFFECT element, since
blend mode is recorded as undecoded in screen.rs and a miscomposited effect would
be tonal and displace nothing. It is the frames; pteff12's ratio is largely
inherited from containing ptframe1. The mechanism may still be right, the element
was wrong, and only ranking rather than confirming showed it.

And it is not an edge effect: ptframe1 and ptframe2 are the only elements whose
residual is higher on FLAT pixels (25.41, 16.54) than on edges (19.85, 9.82).
Signed, ptframe1 renders 88.4 against the capture's 129.1 with 0.1 % of pixels
render-brighter. Body intensity, one direction, after a global tone LUT.

Filed in BLOCKED.md against HANDOFF 5a7f34d as an ask for the blend/alpha bits. I
am not brightening them to match.

Also: suppressing the FOCUSED button changed zero pixels, opaque magenta included,
while ptbtn02/03 change thousands. That looked like a defect and is not --
screen_view.gd:746 documents that a focused button draws its record instead of its
base, covering it at 100.0 %. The null re-derives that claim at a stricter
standard than the measurement behind it.

6af06bd595 port: localise the menu residual -- nothing is displaced, and the split I expected is absent
tools/port/edge-residual-map tiles the frame at 64 px and runs the shift
discriminator inside each tile, which is what edge-residual-kind's reach statement
said it could not do. Division agreed with the Decoder: the map is mine, the
element inventory is theirs.

The first control failed and that is the useful part. A known +2 px displacement
localises perfectly but reads back +0.839 -- the slope is a linearisation and
saturates. So there are two controls now: +1 px asserts localisation AND magnitude
(+0.949), +2 px asserts localisation and sign only. A hot tile's slope is a floor
on the displacement, never a ceiling.

Result: every dx and dy in the top ten tiles is under 0.1 px. Nothing in the hot
region has moved, locally or globally, so the misplaced-soft-element candidate now
has no support on this screen. Hot tiles cluster at x 384-704, y 64-256 plus an
outlier at 640,576; the tool names nothing and the list has gone to the Decoder.

And a null: I added a flat-pixel column expecting two families, edge-only against
hot-everywhere. The hot tiles run continuously 1.24..3.37 across a median of 1.84.
What nearly manufactured the split was carrying over the frame-wide POOLED ratio
of 3.16 as the baseline -- pooling is dominated by the tiles with the most edge
pixels. Same quantity, wrong population; caught because the baseline was computed
before the claim rather than after.

f4351b0b8c port: run the peer's shift-vs-blur discriminator -- the menu is not misregistered
They proposed the test and said they had not run it. It needs the port's render
beside the capture, so it was mine: a shift makes the signed residual track the
gradient (and the fitted slope is the shift in pixels), a blur makes it track the
laplacian. New tool, tools/port/edge-residual-kind.

Controls first, and they are not optional: a known +1 px shift reads back as
+0.938 px (r +0.789), a known blur as r -0.896 on the laplacian, neither leaking
into the other's channel.

Result: -0.010 px, -0.009 px, laplacian r +0.103. Flat. Any whole-frame
translation is under a hundredth of a pixel, and the weak blur term has the
opposite sign to the blur control. Misregistration is excluded.

Reach: whole-frame fit. One misplaced element is a small share of 38 752 edge
pixels and would not move these numbers -- this excludes a GLOBAL translation,
not a local one. A misplaced soft element remains untouched.

Exit codes 0 or 2, no 1 -- it classifies, it does not judge. The control-failure
branch verified by raising the thresholds: report suppressed, exit 2.

Also: GP_DIALOG 2/3 restored to authored/flow.json. I declined to re-add it on a
relay; they have now taken the ja capture (HANDOFF at 5a7f34d) -- 1.82 % of pixels
in four bands, EASY/NORMAL/HARD not among them because JP keeps Latin script. My
objection stands as an objection: adjacency never implied a language pair, and 26
of 65 adjacent pairs differ in button count. The claim now rests on a capture
instead of on that inference.

5738b8328f port: refute the peer's tone/geometry positive control, and label the number that misled it
docs/re/structures/title-residual-tone-vs-geometry.md validates its per-level-LUT
instrument with a positive control on the main menu, on the grounds that "the port
measures only 0.06 % of pixels differing, so geometry is essentially right".

That 0.06 % is verify-capture's, and it counts pixels differing by more than ~64
levels -- a gross-displacement detector. It is blind to sub-pixel offsets and
antialiasing differences, which are exactly what a per-level LUT also cannot close.

Measured: after the LUT, the menu's remaining residual is 6.94 on edge pixels and
2.20 on flat ones, 3.2x. Known negative -- render vs itself under a pure gamma --
leaves 0.00, exactly, because a per-level LUT inverts a per-level effect perfectly.
So the concentration is spatial and the menu is not a geometry-free control.

Their conclusion survives: the title's 32 % never depended on the control. The
refutation is of the validation only, and I say so.

The half that is mine: verify-capture's header now states what the diff column
thresholds and what it therefore cannot establish, next to the number itself.

Not settled: whether the menu's spatial error is misregistration, antialiasing, or
a misplaced soft element. This does not separate them.

56872cb65f port: decompose the menu residual -- 55 % of it is tone, and the control says that is real
verify-capture has said for weeks that the RMSE "has a floor" because the capture
carries the game's tone ramp. Nobody measured the floor. Aligned luma RMSE is
10.60; one fitted monotone transfer curve takes it to 4.77.

A fitted curve always removes something, so: the same fit against an unrelated
capture (EXTRAS) removes 27 %, against the matched pair 55 %. The tone difference
is pair-specific, not the fit absorbing variance.

Nothing in the port changes. I cannot say which side's tone is wrong and I am not
tuning to match. What is new is a bound: 4.77 of the headline number is not tonal.

Also recorded: my first pass at this compared a 1280x720 render against a 1279x675
capture and reported a uniform 75.6 % difference. verify-capture corrects exactly
that, in a comment I had read, and I reached past it.

2fc8f733cc port: the independence rule, and a workflow defect on its fourth occurrence
Their observation is the one thing left worth converting into a habit: the first
genuinely independent pair either of us produced this week happened by accident. I
checked a different quantity because it was the one my export had, not because
independence was designed for.

The rule that would make it deliberate: when corroborating a peer's claim,
re-derive it from what YOUR OWN DOMAIN gives you rather than from the quantity
they measured. Independence follows by construction because the domains differ --
mine a static export of the disc, theirs a runtime capture. Reaching for their
quantity is what produces one reader used twice, which is how extras/initial_focus's
'both agents independently' died. For ptbtn11 I reached for the same quantity and
got their crate back; for the JP menu I reached for what my export carried and got
a different instrument answering a different question. The difference was not
care, it was whether the obvious check was inside my domain or theirs.

Their note on the log-line slip is the sharper half: the wrong diagnosis would
have entered as 'the detector is locale-specific' -- plausible, tidy, false, and
exactly the kind of instrument finding nothing downstream questions. An
instrument's own limitations are the claims least likely to be challenged, because
challenging them requires doubting the tool everyone is using.

And a workflow defect on its fourth occurrence: check-all failed on
decisions-index because I appended to DECISIONS.md while the suite was running. I
have regenerated and moved on three times without naming it. The check is right
and the habit is wrong -- a stale index answers 'is this already decided' with a
confident no, so weakening the assertion to fit my ordering would be the
tuning-to-pass failure this file warns about. The rule is one line: write the
entry, then start the suite.

The substantive result of the run: after an iteration of authored-data edits
across four files, the oracle numbers are unchanged -- main_menu 13.21, extras
13.38, title 14.16. Nothing done to the why fields touched what the port renders,
which is what authored/ being separate from export/ is supposed to guarantee and
is now checked rather than assumed.
