59cf6d8608 port: withdraw "a third independent route", and measure the dwell residual I had only inferred
Two corrections to my own file, one from the Decoder and one from a GPU.

1. "60 NOW STANDS ON A THIRD INDEPENDENT ROUTE" IS WITHDRAWN. I recorded it last
iteration and challenged it in the same breath -- three routes to one number are
weaker than they look if they share an upstream assumption -- but I wrote the
claim down first and the caveat second. The Decoder audited it and agreed: route
B needs "the guest presents 60x/s", from the vblank histogram UNDER Xenia's 60 Hz
limiter; route C needs "the vblank is 60 Hz", that limiter's cvar; route D is a
wall-clock duration that lands on 60 only because the vblank is 60 Hz. One
witness in three coats.

 What survives is conditional and better, established by MANIPULATION rather
than agreement -- forcing 30 Hz gave 30.2 units/s, 60 Hz gives 59.8/61.3:

    units per second = THE DISPLAY REFRESH RATE.

It becomes "60" only through a fact this corpus has never measured: an Xbox 360
outputs 60 Hz. A hardware specification -- solid, and belonging CITED as a spec
rather than folded in as a third measurement.

📌 The conditional form justifies this port's construction rather than excusing
it. "units/s = refresh rate" says what to do on hardware that is NOT 60 Hz, which
is exactly why a time-based clock at a fixed 60 units/s is right where a
frame-based one would drift. `kind` stays `authored`, and the reason is now
sharper: the measurement is of a RELATIONSHIP, and the constant that closes it
comes from a datasheet.

2. THE +1.2 / +1.6 UNIT DWELL RESIDUAL WAS FRAME GRANULARITY -- measured now,
not inferred. I attributed it to the exit check's granularity without testing it.
The GPU makes it testable: same boot, same declared groups, 65-66 fps instead of
17-25.

Pre-registered: shrink roughly with the frame rate, so <=0.5 units at 65 fps.

  publisher  4.27 / 4.26 / 4.27  mean 4.253 s  residual +0.20 units
  developer  3.50 / 3.52 / 3.50  mean 3.500 s  residual +0.00 units

From +1.2 and +1.6 to +0.20 and +0.00. The prediction held. ⚠️ It also means the
4.270 / 3.527 quoted elsewhere carry a rendering-rate term; 4.250 / 3.500 is what
the port hits when the renderer keeps up.

Housekeeping: Xvfb did not survive the restart again -- the exact failure the
check-all display guard was written for, now with a second occurrence. Restored;
the port runs on the GPU at 65-66 fps.

Not settled: findings 3 and 4, both still without a surviving named cause; the
clock origin, where their FRAMES=9000 capture reached 96 % of the movie and
FRAMES=11000 should clear it; the ~1.0-1.2 menu residual.

907b2b5487 port: 60 units/s stands on a third route, and the open half is immaterial here
The Decoder reconciled three of their own pages that held incompatible positions
-- 2 units per guest frame, time-integrated at 56.8, and 1 unit per present --
with one mechanism: the clock advances ONE UNIT PER VBLANK, and presents may be
dropped without the clock caring. It explains steps that are always multiples of
17, and the same animation spanning 21 labels in one capture and 33 in another,
which a strict per-present clock cannot produce.

Their rate result is a manipulation, not an observation: 255 declared units take
4.263/4.162 s at a 60 Hz vblank and 8.450 s at --framerate_limit=30. The vblank
rate sets the unit rate; a console vblanks at 60.

So the justification for 60 has now been "2 units per rendered frame" (retired),
"the game presents at 60 Hz" (superseded), and now "one unit per 60 Hz vblank".
THE NUMBER HAS NEVER MOVED. Worth noticing rather than celebrating: a value whose
reason changes three times while it survives is either robust or
under-constrained, and the honest label is still `authored`.

📌 THIS PORT INSTANTIATES THEIR NULL MODEL, which is the one thing this side can
contribute to that argument. Their reasoning turns on "a time-integrated clock
predicts 4.25 s in BOTH conditions". This port IS a working time-integrated clock
at 60 units/s, and its splash dwell across a 4.0x change in its own rendering
rate is 4.28/4.26/4.27/4.26 s -- flat to 0.5 %. Their counterfactual is
demonstrated rather than assumed.

⚠️ Labelled: that is evidence about the NULL, not about the game. It says what a
time-integrated clock does, not what the game's clock is.

🟡 And per-vblank vs per-present stays open, with the discriminating experiment
named on their side. IT IS IMMATERIAL TO THIS PORT AND THEY SHOULD NOT RUN IT ON
THE PORT'S ACCOUNT: the two models differ only when the console DROPS a present
-- per-vblank keeps real-time pace through a drop, per-present slows. This port
is time-based, so it matches per-vblank exactly and would run marginally ahead of
per-present during drops only. On a console presenting every vblank they
coincide, and these screens are a handful of quads.

Nothing in the port changes.

Not settled: findings 3 and 4, both still with no surviving named cause; the
clock origin, which the Decoder reports blocked because no capture reaches the
title; the ~1.0-1.2 menu residual; the allowance's grep trigger.

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.

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).

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.

e59bb621e4 port: audit the remaining multi-leg claims -- the pattern I predicted is not there
I have listed 'four unaudited multi-leg claims' as open for several iterations and
said I expected the same inversion in them: a count standing in for an exclusion
argument. Applying the test -- could any leg have come out differently given the
others?

loop_start_why holds. Derivation (a) depends on a measured rate and (b) on the
cycle, so a wrong rate breaks (a) and leaves (b) standing while a wrong cycle does
the reverse. They fail independently, which is what 'two derivations' was
claiming. Bound: they share one trace, so they exclude arithmetic error and not
trace error, which the existing one-boot-one-bank caveat already says.

arithmetic_why holds. The corpus's 28.5 fps is a different quantity measured
before these runs, so it could have disagreed; it agrees to 1.4%. Corroboration
rather than restatement.

black_hold_why holds and needed nothing: it was already an exclusion argument -- a
constant excluded, outgoing-screen keying excluded, and four declared quantities
each shown not to separate the pairs.

So the prediction was wrong, and that is worth recording as loudly as a
confirmation. Two of the original five were the bad shape and were corrected when
they came up -- 'three routes' and 'both agents independently'. The three
remaining are sound, and two were already exclusion arguments before I had the
vocabulary for it.

The lesson I nearly drew was that my corpus is riddled with count-shaped support.
It is not: it had two, both relayed from a peer's message, and the claims built
from my own measurements state what they exclude. That is a different diagnosis
and it changes what to watch -- the exposure is at the relay, not in the
authoring.

Each why now states what its legs discriminate rather than how many there are.

98d02e7c24 port: my triage under-counted, and three uncited measurements surfaced behind it
Their audit found 9 of 57 HANDOFF sections asserting measured or
undecodable-with-reach citing nothing openable, 84%, including one they had sent
me: '(B) from EXTRAS DOES go black', delivered as an inline frame table while
data/fade-four-transitions.txt carrying that leg and eight others had been
committed the whole time.

It had already landed here uncited. timing.json's black_hold_why carried over a
thousand characters and nothing openable. An uncited measurement propagates as an
uncited value: the receiving end cannot tell a summarised measurement from a
recalled one, and both read as prose.

And my triage had missed it along with seven others. Last iteration I reported 13
provenance claims among the 52 and labelled them; the count was wrong because my
sibling match was literal, so black_hold_why did not match black_hold_units, nor
loop_start_why to loop_start_s, dwell_why to dwell_seconds, loop_leaf_why to
loop_leaf_on_screens. Eight more, all hidden by a suffix. It was 21 and I stated
13 confidently. All eight now labelled from their own text; coverage 16 to 38.

Three uncited MEASURED fields in one file -- loop_why at 1400 chars, loop_start_why
at 1041, voice/presentation_why at 1402 and authored -- and all three were
detailed rather than sloppy. The detail is what made them look sourced: a why that
recounts a measurement carefully reads as well-evidenced because it is careful.
That is the quality-correlated blind spot one level down -- not 'well-evidenced
values never declared themselves' but 'well-argued prose never cited anything'.
The authored one now cites the open question it stands in for.

A false positive in my own extractor surfaced in the same pass: presentation_why
was reported DANGLING on 1118268 and 1171516, byte counts read as commit shas
because they are seven digits of valid hex characters. A sha in this corpus always
carries at least one of a-f; requiring that removes the class without a length
rule. A wrong verdict for a fabricated reason, the fourth of that family and this
time in the auditor.

6f8211a560 port: triage the 52 unlabelled whys -- 13 were provenance claims, 2 failed on sight
Their closing point was the sharp one: the audit's blind spot fell exactly on
values that were well-evidenced. The three SE cues had measured provenance, byte
offsets and careful text, and nothing about them looked unfinished, which is why
they never declared themselves.

So 'not every why needs a kind' does not excuse the other 52. Split by whether the
why sits beside an actual value: 39 are section prose, _ blocks and group
explanations where a label would be mislabelling to satisfy a counter; 13 are
provenance claims and all were unlabelled.

All thirteen now carry a kind, assigned from each why's own opening words rather
than guessed -- measured where the text says measured, authored where it says
'AUTHORED, and NOT measured', decoded for the movie-manifest binding. Coverage 16
to 30.

Two failed the citation check the moment they became visible.
bgm/main_menu/loop_why was measured with 1400 characters of prose and nothing
openable; it described three watched wraps and cited no file, while the
measurements sat in docs/re/data/menu-bgm-loop-measured.txt and -loop-start.txt
the whole time. navigation/input_during_transition_why was authored and said 'ask
the RE agent' without naming where the question is recorded -- a pointer with no
destination.

The second is worth a rule: an authored kind still needs a citation, and the thing
to cite is the open question the choice stands in for. Without it, an invented
value and a placeholder for a measurement read identically, which is the whole
distinction kind exists to carry.

The denominator is not a target and the tool now says so where the number is
printed; 41 remain unlabelled on purpose.

The mechanism generalises past this audit: a blind spot that correlates with
quality is invisible by construction. The unlabelled entries were not the sloppy
ones, they were the ones so well-evidenced nobody thought to mark them, and the
audit was measuring self-declaration rather than grounding.

Their register measured 83 of 86, 97%, with the identical omission -- never
printed. Their three gaps are unregistrable by construction, bare identifiers that
would match every live mention, the same limit as my own collision case. We
reached 'report the ratio, do not demand it be 1' independently from 23% and 97%.

82e3755bb7 port: a capital letter hid a refuted claim; and band levels answer what alignment could not
Three findings, two of them defects in my own checkers.

Changing the KIND of quantity answered the P4 fidelity question on the first
attempt. Four attempts at sample-exact difference-signal alignment produced four
failures and no verdict -- well past the Decoder's rule that two failed attempts
at the same measurement are evidence the quantity is wrong, not the parsing. Band
energies need no alignment at all: both transcodes match their sources to 0.66 dB
worst-case across four bands, while an unrelated movie lands at 19-20 dB. Two
populations an order of magnitude apart, so the 1.5 dB tolerance sits between
measured values rather than being picked. Asserting in check-all with the known
negative on every run, not behind a flag. It also diagnoses the failure it
replaced: matching spectra mean same content at same level, so the difference
signal's failure is my alignment, now by evidence rather than assumption. The
difference path stays report-only. Band agreement cannot tell a faithful
transcode from one that kept the spectrum and mangled the waveform -- weaker than
P4 wanted, and what I can support.

check-claims held 'no loop-point field has been identified' in its register the
whole time and matched case-sensitively, so a capital N at the start of a sentence
hid a registered dead claim in BLOCKED.md -- the one document whose job is to say
what is still open. The correction had reached authored/audio.json and not the
blocked list, which is exactly the failure that file's own why warns about.
Matching is case-insensitive now and immediately surfaced five more unmarked
sites, including a whole DECISIONS section still describing the refuted state. All
six fixed: four tokened, two rewritten with the shipped values. Controlled with a
planted capitalised revival.

And --control caught its own harness: it perturbed only the first occurrence of an
anchor, and the Decoder's delivery heading now appears twice, so the check read the
untouched duplicate and passed a wrong contract. A perturbation that does not
reach every copy makes a check untestable silently. First time a control has
failed because of a change in someone else's document rather than my code.

Not accepted from the same message: the (A)-skips-a-movie row is NOT stale. It
reads (a) ANSWERED, cites Q9, and points at flow.json's skippable: true. Reported
back rather than quietly 'fixed' -- marking a live row stale is the error their
own message is about.

Every asserting check passes.

a3a53ac3f1 port: the ordered pair determines the gap; nothing declared predicts it
Their run gives five replicates with no variation -- title->menu 3,3,3 and
EXTRAS->menu 2,2 -- while every differing value comes from a different ordered
pair, and the same origin gives different values to different destinations. The
origin constrains; the ordered pair determines.

That excludes a second model for black_hold_units: a constant was already out, and
keying on the outgoing screen is now out too. Only an ordered-pair key survives,
needing a measured value per pair.

Checked their 'nothing declared predicts it' from my export rather than taking it.
Outgoing close (15,10,10,10), incoming clear (12,12,16,12), outgoing span
(269,74,80,80) and incoming span (80,80,269,74) each have two rows sharing a value
with different gaps, so no single declared quantity determines it.

Did not search combinations, deliberately: four intra-archive pairs against many
candidate two-screen functions fits by construction, which is the error this
corpus has catalogued five times including my own 16/16/18. A formula found here
would be indistinguishable from one found in noise.

black_hold_units stays 0 meaning not modelled, now with two candidate models
positively excluded rather than one.

398bf0dbb1 port: escalation resolved -- a uniform black hold is positively excluded
Their measurement orders the four gaps by the screen being LEFT: menu 0 and 1
frames, EXTRAS 2, title 3. Direction, button and incoming screen are each
positively ruled out -- the same pair both ways differs, (B) gives 0 and 2 while
(A) gives 1 and 3, and an incoming menu takes 3 from the title and 2 from EXTRAS.

That resolves the escalation I raised: a uniform value is not merely unsupported
but excluded, so 0 is no longer one option among several. It is the only honest
uniform choice, because it models the gap as absent rather than as constant.
black_hold_units is unchanged at 0; its justification is replaced.

And my own rule is now refuted rather than unadopted. Gap plus the incoming
screen's opening black-clear held at 16/16/18 on three transitions; their fourth
gives 16, 14, 16, 18, and decisively the two transitions with the same incoming
screen have different gaps, so the incoming screen cannot determine it. A fourth
point did to a three-point fit exactly what it should.

Not keying per outgoing screen: three screens with one value each restates the
data, which is the objection I raised against my own 16/16/18. BLOCKED row
rewritten to ask for a second value on any one outgoing screen.

82ae10a002 port: re-derive black_hold_units against four measurements rather than inherit it
They answered ask #2 -- the gap is deterministic, not a load -- and held me to
re-stating the choice against four measurements (0, 6, 4, 6) rather than the three
it was made on. That is my own standard for check-all's stale allowance turned
around.

The arithmetic moved against 0: it costs 2.0x the best fit on four measurements
against 1.7x on three, and is now the minority outcome, wrong on 3 of 4 where a
uniform 6 is wrong on 2 of 4.

Still 0, because the reason was never the fit -- it adds no black the game does
not have, and is measured-correct for a real transition rather than for an average
of them. Picking 6 because it appears twice is choosing a mode from four samples
when their finding is that a rule exists and nobody has found it.

But one leg is gone and is not being kept quietly: part of the case for 0 was that
the quantity might be machine-dependent and unauthorable. It is not. That removes
an excuse without supplying a value.

Added a tripwire: if the gap is non-zero in most transitions and no rule emerges,
omitting a real quantity stops being caution and becomes a different invention.
The port is wrong by 4-6 units on three of four known transitions and the why now
says so.

Also records as settled: the outgoing ramp is the declared final ramp, my {8,10,10}
against their measured multiset, two independent routes.

5e7bc368f7 port: black_hold_units 9 -> 0, and not the value that fits best
The Decoder measured the black gap on three transitions: menu->title 0 units,
title->menu 4, EXTRAS->menu 6. Not a constant, and 9 was outside the range
entirely -- wrong for all three by up to a sixth of a second of black the game
does not show.

Did not take the best-fitting value. A uniform 4 minimises total error (6 against
0's 10); that is fitting three samples. 0 has a reason that is not a fit -- it
adds no black the game does not have, the tie-breaker input_during_transition
already uses, and it is measured-correct for one real transition. The error is now
a missing gap of at most 6 units on two transitions rather than an invented one of
up to 9 on all three. Boot artifact unchanged at 0.0009% differing.

Their EXTRAS run vindicates the earlier refusal: B from EXTRAS goes black for two
completely empty frames, so the two-line change I declined would have been wrong
for two of three transitions.

Also: the declared final ramp is confirmed from my side (title 8, main_menu 10,
extras 10 -- their exact multiset), needing no constant. And exit_ramp_units
defaults to 24.0, the number HANDOFF told me to author and I refused, on a branch
that cannot execute: 866 keyframes across 16 screens, 0 untimed.

And origin/main is the stale era -- verified 0 145 left-right, tip 2026-08-29,
still carrying the pre-fix association. The per-iteration merge has been a no-op
for days, its 'Already up to date' reading as 'I am current' while meaning 'main

8adae30d1a port: the plate pulses -- restore the looping record, over the base rather than instead of it
Ask #1 measured: held at the title with no input the plate oscillates ~23 cycles
per window with no decay and NEVER goes off -- floor 159 thresholded pixels,
pulse bottoming at 714. A glow alone cannot do that (0 -> 80 -> 0); a steady base
plus a pulsing glow can, and 714/1520 are base-only and base-plus-glow.

The port already had the base right: ptbtn00's fade to 0 at t=244 is its EXIT
ramp, and while held the base sits at alpha 255. The glow was missing.

The defect was in the renderer, not the entry I deleted on 2026-08-29. _draw
treated a looping record like a focused one -- drawn INSTEAD of the base, which
is right for a focused button and wrong here. I deleted the right thing for the
wrong reason. A looping record now draws OVER the base and the entry is restored.

Rendered: 95.68 base only, 115.52 at peak, period 1.980 s against a declared 120
units = 2.000 s, ratio 0.990. Visible on the boot path; not under --screen
--overlay, where a static overlay poses at its arrival by design.

Authored in UNITS on their instruction, with their three limits verbatim: one
boot, does not distinguish boot from attract title, and 714/1520 is not an alpha
ratio so no duty cycle is inferred.

3c71962698 port: the PRESS (A) plate could not be drawn at any instant -- four faults, and a misquoted number
1. --time= was silently ignored on any screen with a settle window >= 30 units:
   pose_at overwrote the requested instant with settle_instant. ScreenView.frozen
   now marks an explicit instant and skips both clamps.

2. press_start's settle window was [0,214] -- the dead stretch BEFORE the plate
   exists -- so its settle instant was t=107, where the element is alpha 0. The
   exporter now rejects intervals in which nothing is visible. title keeps
   [160,236], the interval the Decoder's draw stream confirmed.

3. My authored looping_focus_records entry for press_start/ptbtn00 drew a dim
   focus record INSTEAD of the plate's own sprite: max 0 vs max 252.5. Deleted --
   an authored guess that overrides a decode with a worse answer is removed.

4. verify-capture passed --time=5.9617 for the title and it was never applied.
   Every title figure it has printed, including the 0.26% quoted to the Decoder,
   was measured at the settle instant under a note claiming t=357.7. Both rows now
   pose by omission and the note matches. title is 0.21% honestly; splashes
   unchanged at 0.01%.

The boot's end artifact now contains the plate (region mean 95.7 vs 33.6).
Corrects last iteration's BLOCKED row, which had the entry's effect backwards.

7844bf5681 port: audit what rests on a single draw-stream run; black_hold_units=9 sits at the top of its range
Their ARM=early disclosure (~40% silent trigger loss) makes every draw-stream
figure n=1. Exactly one port constant depends on one: the black hold. Three of
its supports have moved -- the 105-frame count they revised to 114, the 2.231
corroboration they retracted, and a run-average rate now known to drift 33%.

Redone on their corrected segments the two runs give 8.95 and 6.71 units, not
one number: overlapping +/-1 error bars are not agreeing central values when one
frame is a third of the quantity. Range ~6.5-9.2, port at the top.

Value UNCHANGED and proposed rather than adopted -- it would be my arithmetic on
their instrument. Filed with the single run that would settle it.

Also checks their statistics: per-boot excesses reproduce exactly, and their
2.3 sigma uses population SD where sample SD gives 1.89 -- cutting against their
own concession. Neither framing reaches significance.

011ba1065a port: their corrected calibration matches the file at all six points; guard the 60 against emulator drift
Counting indices/4 lands every transition where the export's declared alpha>0
count changes, within a half-open boundary. Their quad counts (1/2 publisher,
3/6 developer) also reproduce exactly when restricted to sprite-bearing
elements -- independently confirming the layerless backdrop is absent from the
batch they log.

Refutation: their drift explains the corpus 4.1% in SIGN but overshoots in
magnitude 2.4x (predicts a 1.369 ratio, corpus shows 1.278, declared 1.214).
The drift was measured in their container and the 4.1% belongs to a different
instrument -- the same transfer I just got wrong with build 4.

Guards keyframe_units_per_second at the constant itself: 60 is the game's
logical rate, not a frame rate, and the 33% drift is not evidence about it.

be643ba58a port: withdraw 'the boot is known too fast' -- the splash dwells are declared and the port already played them
The Decoder measured both splashes over 3 cold boots: publisher t=0..255,
developer t=0..210, the developer agreeing with wall clock to 1.1%. The port
emits each declared value plus the 9-unit black hold, exactly. No code change.

My error was the generalisation, not the arithmetic: build 4 is the title, whose
exit is caused from outside its timeline, so it holds; a splash's exit is caused
by nothing, so it plays out. I used the one boot screen the port is unaffected
by to overturn the two it governs. Declining to scale by 9x while adopting the
conclusion that implied was half a caution.

Also refutes their two splash boundaries as not comparably anchored: 2.237 vs
2.414 units/frame in one boot, and the publisher has a glow symmetric with the
developer's three.

b366e404ee port: the clock freezes at settle -- my window is the game's, and the boot is known too fast
The Decoder measured build 4's top-level clock stopping inside [160,236]. The
exporter computes title's settle window as [160,236,198] from the file alone.
Same interval, two independent methods -- the first evidence for the settle
instant that does not come from our own renderer. ptcopyright reaching alpha
255 exactly at t=160 agrees from a third direction.

Corrects a claim in three places: timing.json, flow.json and boot.gd all said a
screen's dwell IS its keyframe group and the port reproduced 'the disc's own
pacing'. Build 4 declares ~120 presented frames and dwelled ~1100. The decision
to hold zero extra stands; the claim that it was faithful does not.

Checks their two declared spans against the file: both exact, with a 106-vs-105
interval-convention quibble that changes nothing.

39209eab05 port: the title's sweeps loop, the black hold is 9 units, and one claim refuted
THREE THINGS FROM THE DECODER, one of which I am not taking.

REFUTED: "the developer splash is one composited quad, the bounding box of the
three logos". The observed quad is 525x259 at (378,155). The three logos'
bounding box is 500x421 at (390,164) -- a 259-tall quad CANNOT contain them, and
palogo_anima alone starts at y=449, thirty-five pixels below that quad's bottom
edge. The observed quad matches the union of gamearts_eff and seta_eff, 521x261
at (379,154), to about four pixels in every dimension -- and both of those are
TRANSIENTS my own census flagged, dark by t=45, so a frame containing that quad
is a build-in frame rather than the settled screen. I cannot see their draw
stream, so I sent the arithmetic rather than a verdict, and the port keeps
drawing three: I will not stop drawing an element on a claim whose stated
identification excludes that element from its own bounding box.

THE BLACK HOLD IS 9 UNITS, NOT 12. I authored 12 from Q7's luminance plateau of
0.17-0.23 s, supported by the menus' transition quad. The Decoder counted
SUBMITTED QUADS instead -- luminance cannot separate the outgoing fade's tail
from true black. Four frames with no sprite quad at all, at 2.284 units/frame
derived from the disc as its own clock, gives 9.1 units = 0.152 s (6.9-11.4).
That overlaps the luminance figure only at the top, and the true black is SHORTER
still since both boundary frames carry picture. My 12 was supported by analogy --
a different screen's quad on a different path -- and a number that fits by
analogy loses to one measured in place. verify-dwell's bound moved with it; both
screens still agree.

THE TITLE'S SWEEPS LOOP. The oracle shows the quad oscillating over its whole x
range and resetting hard, one reset in the first title dwell and two in the
second. The loop-length field could NOT have settled it, correcting a hope I had
stated: both records declare exactly their last keyframe time, slack zero, and
"loops at 600" and "runs once for 600 and stops" write the identical header.
Verified on the two sweeps' LCM, since their periods differ: 600 and 720 realign
at 3600 units, mean diff 0, against 0.438 at half that.

Scoped to the title. The menus declare the same lengths but the oracle
measurement is of the title, and my own weak evidence points the other way there
-- best match with the sweeps off-screen, three times worse mid-screen, against a
73% on-screen duty cycle if they looped. Two weak signals in opposite directions
is a reason to scope, not to pick.

6c78b3cda9 port: the publisher residual was a missing black hold -- we had both dismissed it
I carried this as "0.03 s outside a composite bound, probably a property of the
bound rather than the game", and the Decoder agreed. Both wrong, and the way it
was settled is the point: I stopped reasoning about the bound and filmed the
transition.

At 0.05 s the port fell straight out of the publisher's fade into the developer
logos -- mean 5.06 -> 0.32 at t=4.20, then 5.65 at t=4.25. NO BLACK FRAME AT ALL,
where the oracle measures a 0.17-0.23 s pure-black plateau (HANDOFF Q7). The
bound was fine; the port was missing a fifth of a second of black, and had been
since P3.

Authored at 12 units because the boot path has nothing to read it from:
publisher_logo and developer_logos each carry a single palogo_eff0, a 1280x720
primitive with ONE keyframe at t=0 -- static, not a transition ramp. The menus'
quad declares black for 12 units and 12/60 = 0.200 s sits mid-range, so the
number is the disc's where a screen has one.

Filmed after: t=4.25, 4.30, 4.35, 4.40 all at mean 0, then the developer logos at
4.45. publisher interval 4.26 DIFFERS -> 4.47 agrees; developer 3.62 -> 3.73,
still agrees. Settled-frame comparisons untouched, as they should be.

THE LESSON IS THE SHAPE OF THE DISMISSAL, NOT THE NUMBER. "A 0.03 s miss against
a bound composed from two measured ranges plus jitter slack is more likely a
property of the bound" is plausible, was accepted by both of us, and was wrong.
The composite bound is why the miss looked small -- the underlying gap was 0.2 s
-- and a plausible explanation for a small number is how a real defect stays
hidden. The film cost one command.

Also recorded: the Decoder has reproduced across two build-ins that the console
NEVER draws ptlogo_back2eff3 (0 draws against ~5 expected), with sampling phase,
invisible draws and position error all ruled out -- but WHY is not established,
and nothing in eff3's record differs from its neighbours. The port keeps drawing
it, deliberately: dropping an element the disc declares on a measurement with no
mechanism is authoring a behaviour neither agent can derive, and nothing this
port gates on would notice, since the flashes live only in the build-in and
verify-capture compares the settled frame.

4031a9c58d port: the plate's period is 120, decoded -- and 105 was falsified with my own ring number
The Decoder found it in the format: a nested record is itself a RATC bundle and
its header's +0x08 is the LOOP LENGTH. A record's keyframes need not fill it and
the slack is a hold at the final pose, so ptbtn00f is 105 units of ramp inside a
120-unit cycle -- the glow rests dark for 15 units. The five ptbtn0Nf records
fill their 120 exactly, which shows the slack belongs to that record and not to
the format. Disc-wide over 1781 timed nested records: 92.3% declare exactly their
last keyframe time, 7.7% more, 0 LESS -- the falsifier never fires.

THE DECISIVE TEST USED THIS PORT'S NUMBER. Both candidates need the same emulator
pacing factor, and the ring measures it independently: declared 120 -> 2.177 s ->
1.0885. 105 units needs 1.211-1.337 to reach the measured 2.12-2.34 s, which
EXCLUDES it; 120 units needs 1.060-1.170, which CONTAINS it. Two different
elements in different bundles, separate runs, tied only by both declaring 120.

My three readings in order are the useful record: 129 (105 + the since-deleted
exit_ramp_units) fitted the measurement for a reason that evaporated; 105 (the
group length) I shipped knowing it was 17% short; 120 is decoded. And the
123-vs-129 pair I once called unseparable STRADDLED the right answer without
containing it -- the sharpest argument I have seen against treating "two
candidates, nothing separates them" as if the truth must be one of the two.

Verified bit-identical 120 units apart (mean 0), 0.061 at a quarter, 0.888 at
half. Still authored because the pinned tag does not expose +0x08; delete the
entry the day a tag does.

THEIR rest() FLAG, CHECKED RATHER THAN ASSUMED: they warned a focus record is the
kind of element rest() mishandles. Censused -- 34 focus-record elements, only 2
with a varying alpha, both ptbtn00f, whose rest.alpha of 80 IS their peak,
exactly the pathology described. The port does not hit it because the plate draws
through the loop path, and the other 32 are constant-alpha so rest() is safe.

d57366a35f port: the focus ring had silently stopped, and the plate's period is now the disc's
BLOCKED said the record-layout change touches five things: pose_at,
settle_units, spin_period_units, exit_ramp_units and the plate. I checked two,
reported that, and did not work the rest of the list.

`spin_period_units` required "the first timed and the second untimed". Under the
corrected layout the ring reads t=0 rot=0 and t=120 rot=360 -- both timed -- so
the rule returned 0 and THE FOCUS RING STOPPED SPINNING. Nothing reported it: a
period of 0 is a legal "this element does not spin".

Rewritten to take the SPAN between the two poses: 120 - 0 = 120 units, the same
number the old rule produced, which is evidence the corrected layout is
self-consistent rather than merely different. Verified the way P5 verified it,
by bit-identity one period apart on the ring's own 60x60 box so the ptloop sweeps
cannot confound it: 0 at +120 units (twice), 8.61 at a quarter period, 8.88 at
half.

Three wrong instruments on the way, and the sequence is the lesson. A whole-frame
`max` saturates on one rotating edge (adjacent frames scored 131 with a mean of
0.022). A live --menu filmstrip jitters by up to a frame, which is ~3 degrees of
ring. And a whole-frame comparison is dominated by the sweeps, which move 480 px
over one ring period. `--focus=<id>` was added so a --screen run can draw a focus
record deterministically, which is what made the check reproducible.

THE PLATE'S PERIOD IS NOW 105, THE DISC'S OWN GROUP LENGTH, and it disagrees with
the measurement. The ambiguity the entry carried is gone -- it used to say the
cycle might restart at t=6 rather than 0 and that nothing separated them; the
group now runs t=0 to t=105, both at alpha 0, and there is one reading. But 105
units is 1.750 s, or 1.906 s scaled by the factor the ring shows between its
declared 120 and its measured 2.177 s -- about 17% below all four corpus timings
(2.12 / 2.19 / 2.34 / 2.31). The old 129 gave 2.34 s, at the top of the range,
which is why it looked right.

129 was the last timed keyframe plus exit_ramp_units, and that constant is
deleted. A period built on a constant that no longer exists cannot stay even
though it fitted better, so the port ships the disc's number and says it is
wrong. Verified bit-identical 105 units apart, 0.83 at 30 units.

5dbc9aeac0 port: delete exit_ramp_units, invert the format's own rule, and guard a scale-0 leaf
FOUR THINGS, and the first is what MISSION section 3 calls the measure of
progress.

DELETED `exit_ramp_units` AND `exit_ramp_seconds`. They were authored because the
disc had no time slot on a group's final keyframe, so the ramp into it was the
one unknown duration per screen. Under the corrected record layout that keyframe
does not exist -- a group is an 8-byte header then frames x {u32 time; 36-byte
pose} and every pose is timed. VERIFIED DEAD BEFORE DELETING: setting it to 9999
(166 s) moved the boot's transitions by 0.04 s, which is wall-clock jitter, and
both uses in ScreenView are gated on a condition that no longer fires on any of
the export's 866 keyframes.

INVERTED THE FORMAT'S OWN RULE. `check.rs` enforced "the final keyframe has no
`t`; the disc has no time slot there" and FORMAT.md stated it. Both are now
backwards, and the validator fired 150 times on a re-export. I had not run
`check` between pinning the tag and measuring against the oracle -- the pixel
harness was green while the format validator was failing on every screen with a
multi-keyframe group. A correctness harness does not replace a format one; they
fail at different layers.

GUARDED A SCALE-0 LEAF, which the Decoder hit in its own renderer: its leaf
branch marked the element drawn unconditionally while the blit returned early on
zero scale, so a scale-0 leaf suppressed its parent and blanked the element --
live on all four loading screens. This port did not have the bug only because
authored/rendering.json happens not to list pgloading_loop5. That is an accident
of a gate written for another reason, not a defence, so `_draw_leaf` now reports
whether it drew and `_draw` falls back to the parent.

ISOLATED THE PACING QUESTION rather than leaving it as a suspected regression.
Legacy association: publisher 4.70 agrees, developer 3.92 DIFFERS. Corrected:
publisher 4.26 DIFFERS, developer 3.62 agrees. Both misses are ~0.03 s outside a
composite bound. The association traded which screen is marginally out; it did
not regress the pacing.

Bumped the pin c -> d for the parser and audio changes. Its headline renderer
change does not reach this port: sylpheed-cli builds from the workspace crate.

7c918006e8 port: the PRESS (A) plate pulses -- authored per element, because 82 of 212 share its shape
The human listed pulsation as first-class and the port drew nothing: the plate's
focus record `ptbtn00f` was never reached, because press_start has no `buttons`
and nothing is focused. That it LOOPS is measured -- the corpus timed the period
four times (2.12 / 2.19 / 2.34 / 2.31 s) and you cannot measure a period unless
the thing repeats.

THE RULE I WAS GOING TO WRITE DIED IN THE CENSUS. The spinning ring is a rule in
the renderer because it has a disc-wide check: 16 of 212 elements match its shape
and all 16 are focus rings. The analogous shape for a pulse -- keyframes varying
only in alpha, first alpha equal to last -- matches 82 OF 212, including
ptcopyright, palogo_sqex, ptmsg and every _eff fade. A renderer rule on it would
make the copyright notice pulse. Narrowed to focus records it matches exactly one
distinct element, and a rule justified by n=1 is a special case wearing a rule's
clothes.

So it is a LOOKUP in authored/timing.json keyed <screen>/<element>, with the
census recorded beside it so nobody widens it later.

The period is 129 units -- the element's own group under the port's existing
model: last timed keyframe t=105 plus the authored exit_ramp_units of 24. No new
constant. 2.150 s at 60 units/s, 2.295 s at the ~28.1 fps the emulator presents,
against measurements of 2.12-2.34.

IT IS A CHOICE AND THE ALTERNATIVE IS STATED: restarting at the group's first
keyframe (t=6) instead of 0 gives 123 units = 2.050 / 2.189 s, also inside the
measured spread. Nothing separates them. t=0 is taken because it is where every
other group starts -- consistency, not evidence.

Verified the way the ring was, by bit-identity one period apart. 20 periods is
43.00 s = exactly 172 film frames: frames N and N+172 differ by 0-1/255, while
the control a quarter-second off (43.25 s) differs by 58.7/255. On the held boot
title the glow-box mean swings 26.0 <-> 37.7.

Merges the Godot port into the reverse-engineering repository, preserving both
histories -- 1019 commits of corpus plus the port's 31, brought in by subtree
merge and then moved into place so git can follow each file across the rename.

The reason is not tidiness. The two-repo split forced the exporter to depend on
the decoders by pinned revision, and that created a whole class of failure that
now disappears: a sha reachable only from a topic branch, orphaned by a
squash-merge, breaking a fresh checkout silently at build time. It also forced a
live read-only mount of one agent's working tree into another's container, which
is why a contract file could move mid-iteration. With a path dependency, a
decoder change and the exporter change it requires land in the same commit or
not at all.

Canary stays separate: it is a fork tracking upstream.

New structure for the long term:

  docs/game/     how the game is NAVIGATED -- menus, modals, prompts, alerts,
                 and in-game flight. Written so nobody rediscovers it. Mostly
                 open questions on purpose; the in-game tutorials are the
                 resource for the flight half.
  docs/port/MODDING.md
                 modding as a constraint on the exporter TODAY, not a later
                 feature: one logical asset in one file (the disc splits nearly
                 everything, and resolving that is the exporter's job), names a
                 person recognises, PNG/OGG/OGV/JSON only, base-and-overrides so
                 re-exporting is always safe, provenance in every file.
  data/base + data/mods
                 generated tree and drop-in overrides, both gitignored
  exchange/      transient inter-agent files, deliberately outside history
  docs/agents/   the team protocol

Both the README and the navigation doc lead with the correction that cost the
most: the oracle is the real game under Xenia Canary. Reborn's renderer is a
hypothesis under test, it has been wrong, and treating it as ground truth
propagated into three documents and both agents before a human caught it.

Scripted modding stays possible without being built: no screen name is hardcoded
in GDScript and there is no native code in port/, which is what Godot Mod Loader
needs to be able to substitute behaviour later.
