02ab62e28d port: sweep my own tool headers after theirs -- two hits, both in verify-dwell
Their audit found one defect in sixteen commands and their point that doing one
and stopping is the failure applies to me: I had fixed verify-screen and
verify-capture and gone no further.

Hit 1: verify-dwell built its target as oracle span + the GAME's black gap and
scored the port against it, correct only while the port inserted that gap. It does
not -- black_hold_units went to 0. On publisher_logo the port runs 0.131 s below
the unslacked target, absorbed into an 'agrees' by 0.15 s of slack that is larger
than the omission it hides. Hold now read from authored/timing.json; the game's
gap printed as its own term.

Hit 2: the tool carried '4 presented frames at 2.284 units/frame'. The number is
right but it is the disc used as its own clock on ONE capture that ran at 13.1 fps
against ~28 elsewhere. Stated bare it reads as a general rate and would contradict
Q1's 2 units per rendered frame, a different quantity at normal speed. The
derivation was in DECISIONS.md; the tool inherited the value alone -- exactly
their defect, and their 'print the population beside the number' fix applies
unmodified.

Not found elsewhere: check-capture's percentages all name their population;
check-claims, check-modding, index-decisions and strip-padding assert no measured
quantities.

d8488640a8 port: my backdrop predicate is exact in GP_TITLE and its reading was wrong
I offered 'a declared opaque-black backdrop distinguishes standalone from
composited' and asked for it to be tested against archives I do not have. It was.

The split reproduces exactly: derived independently from the disc, GP_TITLE gives
12 with and 4 without, the four being entries 0-3 -- my build_00, build_01,
press_start, press_start_jp -- with element names matching. Two genuinely
different paths, my export against their disc reader.

The reading does not survive. Disc-wide the predicate is rare, 76 of 965 builds at
7.9%, with GP_HANGAR_ARSENAL 0 of 390, GP_OPTIONS 0/14, GP_PAUSE_MENU 0/6. Read as
'composited' it makes 92% of the game composited, which the archives do not
support.

What survives is narrower: it separates screens that BEGIN FROM BLACK from
everything else, and their sharpening is the part I would not have reached -- the
negative class is heterogeneous, so a two-way rule cannot express it.

My caveat named the exact test that refuted the reading, but I still put the
refuted interpretation into verify-screen's header as a stated fact while the
hedge lived in DECISIONS.md. Corrected, with the 7.9% figure and an explicit do
not carry this into the four unexported archives. Hedging in the write-up does not
protect the claim shipped in the tool -- the same delivery gap as the
capture-phase term, repeated four iterations after fixing it once.

Within GP_TITLE the rule is exact and --black for those twelve is justified from
the file rather than assumed.

c6735f55a6 port: audit the --black premise -- declared on 12 screens, assumed on 4, all composited
Their finding that screen render --black's premise is declared on the splash
builds is checkable across my whole export, and verify-screen passes --black to
all sixteen screens on that premise.

Audited by asking whether a screen declares a full-screen untextured primitive at
t=0 with fade_argb 0xff000000. Twelve do -- pteff00 on both titles, both menus and
both extras, palogo_eff0 on all four splashes, pgloading_eff00 on build_12/15.
Four do not: press_start, press_start_jp, build_00, build_01.

All four exceptions are composited rather than standalone. press_start is one
element, the plate, whose own name_why records it is composited over the title.
build_00/build_01 carry the pgloading_* set without the pgloading_eff00 backdrop
that build_12/15 declare.

Harmless where used: verify-screen gives --black to both renderers so the
assumption cancels in a consistency check, and verify-capture already scores the
plate over the title rather than on black. The exposure was real and the tooling
had already routed around it, which could only be established by looking.

The rule that falls out: a declared opaque-black backdrop distinguishes a
standalone screen from a composited one, derivable from the file rather than from
a name. Recorded as a rule with its evidence -- sufficient as observed, not proven
necessary, on four exceptions.

ec37e8f9fc port: the fifth member of the family is mine -- 'drawn' read as 'visible'
Their revision confirmed from my export exactly: palogo_sqex_eff ramps 0->255 over
t=0..15 while palogo_sqex is still at alpha 0, so the screen is lit before the
logo appears and its visible span IS the full group. Their withdrawal of the
systematic stands on my data too.

Checking it exposed my own version of the error. My earlier 'visible 0..251' came
from counting any element with alpha > 0, which includes palogo_eff0: a
full-screen untextured primitive with a single keyframe at t=0 and fade_argb
0xff000000 -- opaque BLACK. Drawn from t=0 and showing nothing. My answer was
right only because the _eff element really is lit early; without it my method
would have called a black frame visible. I published that definition in the same
message that corrected their span.

So the family has a fifth member and it is mine: 'visible' read as 'drawn'.

Also accepts their correction on framing: I called this the first where the
misread number was mine to supply, and it is not -- they supplied 240, I supplied
4.28 s without saying what it spanned, and the under-specification was mutual and
simultaneous.

Conclusion unmoved: full group 255 and 210 units, ratios mean 1.0146, Q1 stands
unqualified.

ccd6fe7b48 port: refute the 8.5% splash-dwell systematic -- it is the span, not the clock
They challenged the dwell agreement: declared spans 240 u and 195 u at 60 u/s give
4.000 and 3.250 s against six cold boots whose ratios all exceed 1, mean 1.085,
implying 54-56 units/s. And that 240 units at 60 should give 4.000 where I report
4.28.

The port does not play 240 units. Their 240 is the visible span, the logo
element's 15->255. The port plays the whole group from t=0, and my export gives
the full spans as 255 and 210 units -- 4.250 and 3.500 s. My 4.28 and 3.58 are
those plus transition overhead.

Recomputed against what the port plays, the ratios become 1.011, 1.083, 1.028,
1.002, 1.001, 0.962 -- mean 1.0145 with one of six below unity, against their mean
1.085 with none below. The systematic largely dissolves.

Their practical consequence does not follow either: the gap is 0.174 s, not 0.42,
and on developer_logos the port runs 0.041 s LONGER than the oracle mean, the
opposite sign.

Fourth instance of the same family after pivot-as-extent, centre-track-as-bbox and
cycle-length-as-motion-duration: a visible span read as a played span -- and the
first where the misread number was mine to supply and I had never stated which
span the port plays.

What survives: publisher still runs long in two of three boots against the full
group. Much weaker than 8.5%, thin at three boots, and no support for changing
keyframe_units_per_second.

0583b15fba port: verify the boot as a sequence -- path, timing and endpoint
Twice I wrote that the boot's 0.00% agreement is one frame, the last one, and the
boot could take a wrong path and still land correctly. Closed, with no new capture
and no new feature.

--boot --shots= writes nothing: _shots is wired to the --script path only. I was
about to build stepwise boot photography; the trace and verify-dwell already
answer the question, so I did not.

Path: the boot logs its transitions, and they match authored/flow.json's declared
sequence exactly -- publisher_logo, developer_logos at 4.26 s, video ADV at 7.78,
title at 152.54 with the overlay raised at the same instant, ending 156.48.

Timing: verify-dwell against the Decoder's three cold boots gives publisher 4.28 s
against 4.297/4.604/4.370 and developer 3.58 against 3.508/3.503/3.366, both
agreeing. And authored/flow.json's dwell is EMPTY by design -- the dwell is
declared and the port plays it -- so these are disc-derived timings agreeing with
three cold boots of the real game with no authored constant between them.

So the shipped artefact is verified on three axes: path from the trace, timing
against the oracle, final frame at 0.00% differing. Still unverified: the
intermediate frames themselves, and the 144.76 s video beyond the fact it plays.

51c85ed691 port: print the capture-phase term beside the numbers it qualifies
Their closing point -- the thread lived in messages and docs/re/, which by our own
rule means it was not delivered -- applies to my side. The capture-phase term was
in DECISIONS.md, but verify-capture is what prints the numbers it qualifies and it
said nothing: a reader saw title 14.16 with no sign that +/-5.56 is inherited from
where the shutter fell.

Now printed per row: title +/-5.56 regression only, main_menu +/-3.78, extras
+/-3.73, and both splashes marked as carrying no free-running element and meaning
what they say. Header records that --leaf-time=0 is a convention, not the game's
phase.

Also names a gap their own update exposes: they landed the leaf facts in HANDOFF,
correctly, but HANDOFF as I read it contains none of them -- their work is on
auto/build-ordinal-audit and origin/main is 145 commits behind. So the facts reach
me only through messages, the channel the rule says does not count. Writing it in
the contract is necessary and not sufficient when the contract lives on an
unmerged branch. My BLOCKED.md and DECISIONS.md carry the status sourced to their
sha so my tree does not depend on a HANDOFF I cannot see.

Second structural consequence of main being stale, after the Cargo.toml pin.

857930a1ac port: close the leaf thread -- rotation_deg verified against the game, self-check abandoned
My sampling alternative is refuted cleanly: their captures report 150 frames
spanning 1..149, indexed by guest VdSwap submissions, not wall-clock. The
wall-clock revival I proposed does not survive.

rotation_deg is confirmed from the running game. Their AABB check predicts, from
the declared scale plus my exported angles, pteff03 400x1080 at +30 deg -> 1135.3
against 1134 observed (0.12%) and pteff03a 400x1440 at -45 deg -> 1301.1 against
1303 (0.15%). First time this session an export value of mine has been checked
against the game rather than against the other decoder -- everything prior ran
disc->exporter->export against disc->their-reader, which shares the source.

The renderer self-check I started is abandoned. I predicted a changed band at x
949..1280 full height for leaf phase 0->30; measured 1177x70 at the top of the
frame, max difference 5.29. The prediction is mine and wrong: the leaf pivot is
[200,90], the source centre, but under 800% vertical scale the mapping from pos to
drawn extent is not the centre-offset I assumed. My arithmetic, not a demonstrated
renderer fault, and separating them costs more than the answer is worth.

Stopping deliberately. They classified the leaf clock as undecodable with reach
after four refuted models and noted the thread has cost both of us a lot for a
quantity nothing ships on. Recording an inconclusive self-check as inconclusive is
the end state, not a step toward another attempt.

14a129ad75 port: apply their linearity gate to my side of the ratio, and find an inversion
Their gate -- a slope is only a rate if its residual is random -- bears on the
ratio we built together, so I checked the half I supply. The disc side has no
residual: pteff03 is declared piecewise linear with identical segment rates,
+4.0000 px/unit over t 0..150 and again over 150..540, then a hold. pteff03a gives
-4.0667 then -4.0625, a 0.1% step. These are declarations, not fits.

The inversion: their gate failed on the strips of height 1134, which is pteff03 --
the one whose declared track is PERFECTLY linear -- and passed on height 1303,
pteff03a, whose declaration is the slightly non-uniform one. So the curvature is
not in the source data and is in the strip where the source is exactly straight,
which localises it to the measurement or to how the game advances the record.

Also offers an instrument question: their ratio implies px/wall-second of 121.7 at
default against 30.5 at limit 15, ~4x slower on screen. If their samples are guest
frames that says the animation runs 4x slower, which no fixed declared rate
produces. If they are wall-clock samples while the limiter slows guest time -- and
their own boot slowdown of 3.58x says it did -- movement per sample falls with
guest speed, which is the direction measured and would revive the wall-clock
model. Their 3.58x and 2.14 are two measures of the same slowdown and disagree.

Marks the 1.87x table's input as known-wrong rather than merely unpinned.

2a8caf03ff port: the off-edge splash residual is not tonal, and I compared it to the wrong floor
Ran the per-level tone correction I said was untested, deriving the curve on one
splash and applying it to the other because fitting and scoring on the same pixels
succeeds by construction. developer_logos off-edge: uncorrected 2.7512, single
gamma 0.85 gives 0.9040, the cross-applied per-level curve gives 1.3795 -- worse
than a single exponent.

The control settles it: publisher_logo scored with its OWN fitted curve gives
1.4209 against 1.4440 for gamma 0.85. A tone curve fitted on those very pixels
improves them by 1.6%. If the residual were a tone-mapping error, fitting the tone
mapping on its own training data would collapse it. The residual is not tonal.

And it is smaller than I made it sound. I called 0.82-1.42 '15-25x the 0.06
rasterisation floor', but 0.06 is render-to-render reproducibility -- the floor for
asking whether the renderer repeats itself. For render-versus-capture the floor
includes 8-bit quantisation on both sides: uniform rounding is RMSE 1/sqrt(12) =
0.289, so two independently quantised images differ by ~0.41 before anything is
wrong. Against that, 0.90 is ~2.2x, about one level in 255.

Same error as comparing an in-box margin to a whole-frame spread, which I flagged
in someone else's work two days ago.

6b75beda54 port: their Route 1 is closed for the whole archive, and the exit ramp fooled me again
They closed three routes to pinning the absolute leaf rate. Route 1 -- a top-level
element moving in the same capture as a leaf, so fps cancels -- failed on the
settled title.

Searched all 16 screens for a top-level element still moving at its settle
instant. Two hits, pttitle on extras and extras_jp, and both are false positives:
it arrives, holds from t=24, and the post-settle motion is the exit ramp at t=52
to 58, which plays only when the screen leaves. Third time the exit ramp has
fooled a census of mine, after counting it as the end of visibility and after
making every normal element look like a flash.

The negative generalises their finding: excluding exits, no top-level element on
any of the 16 screens moves at rest. holding clamps every top-level element at its
own hold and the only post-settle keyframes are exits, so no capture of any screen
in this archive can carry a top-level clock alongside a free-running leaf. Route 1
is closed structurally, not just empirically.

Also states something about the port's design I had not: everything that moves on
a settled screen is nested. The three free-running clocks -- looping focus record,
spin, leaf -- are all sub-records, which is now explained rather than observed.

Also marks the 1.87x table conditional, since its input is the rate they cannot
pin.

bb52a4ae87 port: nested leaves may advance at half rate -- the title sweeps ship 1.87x too fast
Their corrected least-squares fit gives 4.287 and -4.348 px/frame against my
declared 4.000 and 4.063 px/unit: 1.072 and 1.070 units/frame, where Q1
establishes 2 for top-level elements.

My port drives everything from one clock -- boot.gd:375, time_units += delta *
units_per_second at 60 units/s -- and the leaf path reads that same clock. So the
title's sweeps cross in 10.0 s where the game takes 18.7, a visible 1.87x defect
in what the boot ships.

Not changed, and not only out of caution: keyframe_units_per_second is authored
from a measurement and governs build-in, transitions and the plate. Changing it
globally breaks the top-level timing Q1 measured; a leaf-only clock is a claim
about how the game works rather than about my renderer. That is a Q1 sub-question
and theirs.

Refutation attempt on their strongest argument: two strips agreeing to three
significant figures constrains the strips to EACH OTHER, not the absolute rate.
Both ratios come from one capture under one fps assumption, so a systematic error
scales both identically and the agreement survives. Their own untested candidate --
1 unit per 1/30 s at 28.5 fps gives 1.053 -- sits within that uncertainty of 1.070.

93d69e6148 port: check their draw-stream result against my export -- three confirmations, one correction
Their oracle run refutes their own 'may not draw these leaves' hypothesis and
confirms my title curve from the game. Checked against my export:

Rotation: the export carries rotation_deg +30 on pteff03 and -45 on pteff03a,
constant across all four keyframes, matching their ROT flag. spin_period_units
returns 0 for four-keyframe elements so the spin override does not fire and the
port draws the declared angle.

Directions: ptloop01 runs -639 -> 1521, ptloop02 runs 1721 -> -839 -- their strip
A and strip B.

Height: a 30-unit phase step changes a band 1121x720 and 1137x720, full frame
height, which is what a 1134/1303 px strip on a 720 px screen must produce.

The correction: their rate check divided 2160 px by a 600-unit cycle to get 3.6
px/unit, but the last segment HOLDS. pteff03 moves over t=0..540 then sits at 1521;
pteff03a moves over 0..630 of 720. Corrected: 4.00 and 4.06 px/unit, predicting
8.0 px/frame against their measured 6-7. That widens the gap from 7.2-vs-6.5 to
8.0-vs-6.5, so 'the rate matches the disc' does not survive the corrected span,
and a lower emulator frame rate moves the prediction the wrong way.

A cycle length is not a motion duration -- same family as a pivot anchor read as a
drawn extent.

b492a639d1 port: the splash floor is glyph-edge antialiasing; off edges the port is ~1 RMSE from the game
The splash rows have no free-running element, so their residual is chaseable
without a phase term. It is not tonal: max 255 with 0.012-0.017% of pixels over
8/255, in opposite directions on the two screens. That is the edge-antialiasing
signature.

Tested against an edge mask from the capture, with coverage checked first because
an earlier attempt on title failed by classifying 92% of the frame as edge:
publisher_logo mask 0.67%, residual 18.30 on edges against 1.42 off;
developer_logos mask 1.44%, 12.66 against 0.82. Non-degenerate masks, 13-15x
concentration. The 1.92 whole-frame floor is glyph-edge antialiasing.

Off the edges the port matches the game at 0.82-1.42 RMSE -- the cleanest
port-versus-game statement in the corpus, and confirmation of verify-capture's
long-standing note that the port is +9 to +12 on sprite edges, measured rather
than observed in passing.

Not everything is explained: 0.82-1.42 is still 15-25x the rasterisation floor,
consistent with the binned tone table leaving about a level of error, but not
shown to be that.

Also records the contamination check after their withdrawal of the A result:
nothing in authored/, docs/port/ or port/ cites it or the '2 of 2' run count.

a890b66b35 port: fit a gamma on the clean rows, and repeat a mistake my own tool documents
The splashes carry no free-running element, so they are the only place to measure
the capture's tone relationship without a phase term. Gamma sweep gives a clean
minimum at 0.85 on publisher_logo, developer_logos and title -- gamma ~1.18 in the
corpus convention, against HANDOFF's 1.34-1.49. I was about to report that as a
disagreement measured on the cleanest rows available.

verify-capture's own header answers it: the tone relationship is a curve, not a
best exponent, and two earlier versions of the tool reported an exponent and were
wrong. The binned table below it shows implied gamma falling with render level --
1.20 at 8, 1.18 at 24, 1.03 at 40, 0.93 at 48 -- with 511026 pixels in the dark
bins against 258823 above. My whole-frame fit recovered the pixel-count-weighted
average of a varying curve and would have published it as the gamma. Third time
this tool has been fitted an exponent, third time wrong.

The residual at best gamma is 1.92-2.06 on the clean rows, ~30x the 0.06
rasterisation floor, so a single exponent cannot close it.

What the clean rows do establish: the splash residual bottoms at 1.92 with no
phase term, so it is a real floor for those screens and still 30x the noise --
the port and the capture differ by something the tone curve does not explain.

998af195e0 port: withdraw the compactness precondition and the free-running claim; the minima are off-screen phases
They challenged the compactness precondition and my claim that the leaf free-runs
in the game. The precondition is wrong and withdrawn -- the same sweep crosses
their box and two renders one plateau-phase apart differ by 11.9 inside it, so
their crop excluded nothing.

Their hypothesis that the game may not draw these leaves makes a testable
prediction: the best-matching phase should be wherever the quad is off-frame. The
x track is (0,-639) (150,-39) (540,1521) (600,1521), so a ~400 px quad is
off-screen at t=0 and t=600 and on-screen from ~120 to ~480.

On main_menu the two RMSE minima are exactly the two off-screen phases, and every
on-screen phase is worse -- their prediction landing precisely. On title the
minimum is at 240, on-screen, with both off-screen phases worse -- the opposite,
fitting the sweep being present in that capture, which ORACLE-CAPTURES.md already
says of these elements.

So 'the leaf free-runs in the game too' is withdrawn as established: my two minima
came from two different screens. What the off-screen coincidence shows is
narrower -- the menu capture behaves as though the sweep is absent, the title
capture as though it is present. It does not resolve their JP tension either.

The settling test is theirs (draw-stream check on a settled title). The
contribution here is that the question has a per-screen answer to look for, and
main_menu is where the absent evidence is strongest.

Their rule -- score inside a region excluding free-running elements and measure
the residual there -- implemented with the mask derived by measurement: five leaf
phases per screen, union of what moves. Free-running area is 3.68% on title, 1.63%
extras, 1.32% main_menu, 0.00% on both splashes.

The control fails. On extras, a 1% threshold masks 9.3% of the frame and removes
only ~16% of the phase term (1.7343 -> 1.4569). The rule is sound but conditional:
their free-running element is a localised pulsing plate they can crop out, mine is
a wide translucent sweep whose contribution is thin and spread. It cannot be cut
out without cutting out the picture.

And they were right that my ~1.0 was too small. In verify-capture's own metric the
term is 5.56 on title, 3.78 main_menu, 3.73 extras, 0.00 on the splashes. My
earlier figure came from a greyscale metric over a narrower phase range -- computed
one way, quoted as if it applied another.

The consequence sorts my oracle rows: the splashes carry no free-running element,
so 2.17 and 3.05 mean what they say; title at 14.16 carries +/-5.56, larger than
the spread between any two of my rows. Those rows are usable for regression at a
fixed pin and not for absolute comparison.

Recorded as a limit, not fixed: no pin removes it, since the term is the game's own
animation sampled at one instant by the capture.

7fe318356c port: the phase result does not replicate, and the failure reframes it
The Decoder established ptloop01/02 and their leaves are identical on entries 4, 5
and 7; confirmed against my export on every field. That makes replication
well-posed: same object, different screen, different capture.

main_menu minimises at 0 units (13.2059); title minimises at 240 (13.9417), with 0
at 14.1604. Spread 1.025 on the title, 18x the 0.0565 floor, so both sweeps are
decisive and they decisively disagree.

The meaning: the leaf free-runs in the game too, so each capture froze it wherever
it happened to be. The phase that best matches a capture is a property of when the
shutter fell, not of the game's rest state -- a continuously sweeping element has
no canonical rest phase to find. My 'phase 0 is the measured best of the cycle'
was measuring the capture, not the game. The hedge I attached was the right
caveat for the wrong reason: I framed a well-located property of a photograph as a
weakly-located property of the game.

Phase 0 stays pinned as a harness convention. NOT tuning it per screen -- 0 for
main_menu and 240 for title would minimise both and would be fitting each
capture's shutter moment, making the harness agree with the oracle by
construction.

Every row with a sweeping leaf now carries an irreducible capture-phase term of up
to ~1.0 RMSE, larger than most margins quoted from those rows.

a860040f2f port: correct the leaf table -- I wrote it before the data printed
ptloop02's leaf is pteff03a, not pteff04, and its x track is -839..1721, not the
same as ptloop01's -639..1521. I filled the row from the shape I expected rather
than from output that had not appeared yet. The two leaves differ in element,
span, track and scale; only the parent position is shared.

4f108562c9 port: cross-check the leaf sweep against my export -- their reading and mine reconcile
Their withdrawal gave coordinates to check my renderer against, and my first
measurements looked like a contradiction: phase-to-phase differences span the
whole frame against their 400 px quad tracking x 921->1041. Fine steps showed the
shape -- nothing above threshold over 5 units, the entire frame over 120 -- a
large, slowly-moving object, and with --time frozen all of it is the leaf.

Reading the leaf record from my own export resolves it. ptloop01: leaf pteff03,
span 600, x track -639..1521, scale (100,600). ptloop02: span 720, scale (100,800).
Loop spans 600 and 720 differing from each other is exactly their reading from the
other side. Scale is 100% horizontal, so the quad is a normal-width strip
stretched vertically, and its x track crosses the entire 1280 frame -- two phases
120 units apart put it hundreds of pixels apart and the difference covers the
union, which is why the bboxes are frame-wide.

Their 921->1041 is a segment of that track, not its extent. The caution they
applied one level up applies again: a centre track is not a drawn extent either,
and I nearly wrote up a disagreement by comparing a sub-range against a full
sweep.

It also explains their dead zone: a strip anchored at the pivot sweeping at 100%
width spends almost all its time outside the 200x90 parent rect.

9d43926231 port: the capture determines the leaf phase, and phase 0 is the measured minimum
Last iteration I pinned the leaf at phase 0 for reproducibility and said which
pose the game shows was not settled by it. Asked the capture, with the decision
rule stated first: the spread must beat the noise floor decisively or 0 stays an
admitted arbitrary choice.

Phase 0 is the global minimum at 13.2059, rising to 14.08 mid-cycle and returning
to 13.2065 at 600 units -- margin 0.44-0.88 against a run-to-run floor of 0.0565,
8-15x, which meets the rule. 0 and 600 agreeing confirms the cycle closes,
independently supporting the leaf's declared span.

The Decoder's point is what makes it readable: the gamma offset moves every
candidate together and nearly cancels in the ranking, so nine renders differing
only in leaf phase compare cleanly on a ~13.2 floor nobody can remove.

Broad minimum -- 0 and 15 units identical to four decimals -- so this constrains
the phase to the first 15 units of a 600-unit cycle, not to a point, from one
capture of one screen.

And the sweep that nearly said the opposite: --leaf-time takes SECONDS, so my
first sweep of 0..500 was 0 to 30000 units, every value past the group end,
returning 13.2059 six times. Third instance of the seconds-versus-units confusion,
after --time=50 and after I wrote the identical-output tell into METHOD. Made
worse because 0 and 30000 genuinely coincide, so the flat reading was partly real.

49958ff090 port: the third clock was in my own enumeration and I did not wire it
Last iteration I enumerated three free-running clocks, wrote that the leaf is
pinned only by --leaf-time, then tested reproducibility without passing
--leaf-time and concluded nothing free-runs on the menu path. The answer was one
paragraph above the experiment that contradicted it.

My own flagged weakness found it: deliberate wall-clock variation via
--script=wait:N, putting the capture at t=96 units against t=369. Spin pinned
only, wait 0.5 vs 5.0 differs by max 91.19 per channel; with --leaf-time=0 added
it is byte-identical. draw_leaf_for is ptloop01/ptloop02, present on main_menu and
not just the title, which is why that row drifted.

verify-capture passed --loop-phase=0 and not --leaf-time=0 -- I fixed the clock I
had been bitten by and left the one I had merely listed. Enumeration without
follow-through fails exactly like no enumeration.

Both are now pinned at all six render sites. main_menu returns 13.21 across three
runs and two renders after different waits are byte-identical.

The number moved 13.26 -> 13.21 and that is NOT an accuracy improvement: pinning
the leaf at phase 0 puts ptloop01/02 at one specific pose rather than wherever the
wall clock left them. A different configuration, now reproducible. Which pose the
game shows at rest is not settled by this.

a04d8a6740 port: enumerate the free-running clocks, and test rather than enumerate
The Decoder's point was that this is an unenumerated set, not a missing guard. The
enumeration is possible on my side and found a THIRD clock: the leaf sets
holding = false explicitly and reads time_units, pinned only by --leaf-time or
--time, biting on loop_leaf_on_screens = [title]. I would not have found it by
waiting for a row to drift.

But the general answer is a test that fails when the set is non-empty. Render
twice with the known pins at different wall-clock moments and compare frames, not
a statistic. --screen + --time + --loop-phase: all 16 byte-identical, though
--time freezes time_units itself so that pins every derived clock. --menu
--script=wait + --loop-phase, where the drift lived: frames differ by 4378 px --
but max per-channel 2.86 against 158.4 for a genuinely moving element, 55x apart.
Nothing moves; the residual is rasterisation noise. The discriminating scale is
what makes the test an answer.

And the reason I nearly missed it: last iteration I reported three pinned runs
returning 13.26 and called the harness reproducible. verify-capture prints RMSE to
two decimals and the residual is 0.0565 -- below its own resolution. The frames
were never identical; the statistic could not tell. I verified reproducibility
with an instrument that rounds away the thing being verified.

Conclusion unchanged: 2.86/255 changes no result.

cf8f001956 port: the oracle harness was nondeterministic and I quoted it for a dozen iterations
verify-capture's main_menu row reads 13.30 / 13.27 / 13.25 / 13.26 across runs
this session while every other row is identical to the digit. I cited those
numbers repeatedly, including in the rest() adjudication.

Cause: the focus ring spins on time_units raw rather than the pose clamped by
holding -- deliberate and correct, since the ring is the one thing on a settled
screen that keeps moving -- so its angle at capture is set by the wall clock.
extras is stable because nothing there spins.

--loop-phase already existed and did not cover it: it pins the looping focus
record phase, while the spin is a second free-running clock I guarded once and
never connected. Extended loop_phase_units to pin the spin too, and verify-capture
now passes --loop-phase=0 at all four render sites.

The control matters because the drift was intermittent -- three unpinned runs gave
13.25, 13.26, 13.26, so three pinned runs agreeing would prove nothing. Phases
0/30/60/90 give 13.2583 / 13.1991 / 13.2637 / 13.2588: the pin is live and the
0.065 spread is the whole of the observed drift.

Non-finding recorded so nobody mines it: phase 30 scoring lowest is not evidence
about the ring's real phase -- 0.065 against a ~13.2 gamma floor is 200x too
small. A margin only means something against the noise it sits on.

No conclusion changes: the smallest margin any of them turned on was 0.14%
differing area.

e005016751 port: count the fallbacks instead of inspecting them; black_hold's absence is now audible
The Decoder sharpened the sweep in a way that invalidates part of how I ran it: an
in-range fallback cannot be caught by inspecting output, because the output looks
exactly like the true case -- the only way to know is to count how often it fires.
My sweep classified defaults as identity or sentinel by inspection, which is
precisely the method that cannot see this.

Counted: rotation_deg -> 0 fires 0 times in 866 keyframes and 178 rest poses, and
ramp is present in authored/. So rotation is read, not invented -- the same
conclusion they reached for design size, reachable only by counting.

The count exposed one I had waved through twice: black_hold_units defaults to 0.0
and its authored value IS 0, so deleting the entry would be invisible -- same
behaviour, no error, and the reasoning in black_hold_why (four measured gaps, why
0 over the better-fitting 4 or 6, the tripwire) silently stops applying. Fixed the
same way as exit_ramp_units: fallback is -1.0 and an absent key raises an error
naming what was lost.

The control is the demonstration: key present 0 errors, key deleted 1 error, and
the render byte-identical either way. No output inspection could have detected the
deletion.

Does not change the value: still 0, still wrong by 4-6 units on three of four
measured transitions, still no rule. Only its absence is now audible.

fe6e4a384a port: sweep the tree for values a deleted entry still supplies -- one instance, already fixed
The exit_ramp_units catch generalises: deleting an authored value does not remove
it if something supplies it silently, and authored/ is where a reader looks and
does not find it. Swept both halves of what I own.

GDScript: every keyed lookup with a fallback, cross-checked against the 121 keys
present in authored/. One hit -- exit_ramp_units, the case already fixed -- which
makes it the sweep's own positive control: the detector found the known instance
and nothing else. The other numeric fallbacks are identity or sentinel and invent
no quantity.

Exporter: 14 serde(default) sites, all attaching to Option, Vec or map types,
where an absent key becomes None or empty and asserts nothing.

My classifier produced a false positive I nearly wrote up: it flagged
also_export: AlsoExport as a semantic default because the type name lacks a
container prefix. AlsoExport is a type alias for a BTreeMap. Classifying a type by
the spelling of its name is the same proxy reasoning as inferring an era from a
line count.

Negative result, but from a check that demonstrably finds the known case.

0be8348a6f port: the refuted 24-unit constant was living in a default; make it loud instead
ScreenView.exit_ramp_units defaulted to 24.0 -- the constant HANDOFF ask 2 told
this port to author and that it refused, since the file's own ramp is 10 units.
The authored entry was deleted as progress when the corrected record layout
removed the unknown, and the default plus boot.gd's timing.get(..., 24.0) made
that deletion a no-op.

Both use sites are unreachable on today's export (866 keyframes, 0 untimed), so
the branch is kept for an older export but no longer invents: the default is -1.0
meaning not supplied, and an untimed group now raises an error naming the screen
rather than fabricating a duration.

My first verification accused the change: main_menu 641941 px and extras 226009 px
changed, on a branch that cannot execute and with no error raised. The cause was
--screen=X --capture= firing at an uncontrolled instant -- t=9.00 in the earlier
run against t=8.00 in the later one, one unit apart mid-build-in. Three runs now
are byte-identical, so it is not noise; the instant is stable within a session and
moves between them. Re-run with --time=1.0 pinned, old against new is
byte-identical on all four screens.

Records the harness limitation: --screen=X --capture= cannot be used for
before/after comparison on an unsettled screen, which also explains the earlier
settle-vs-rest confound.

Also corrects my overstatement that other tools call the CLI -- verify-screen is
the only one, checked.

dbbf28e22f port: my branch IS the stale era, and verify-screen's reference was never its own build
Told the Decoder their diagnosis was wrong. They were right. ui_layout.rs is md5
b6c19d08 in my working tree, at HEAD, on my pushed branch and on origin/main --
one file, stale marker present, tree clean.

What misled me is the same trap a third time: CARGO_TARGET_DIR is a shared
/sylph-home/port/target-container, so two source trees write one binary and cargo
fingerprints per source path -- each build reports Finished while the binary on
disk belongs to whichever tree wrote last. A CLI built from my workspace is
3a39fce (stale, rest t=70), identical to one built from origin/main; the binary
verify-screen actually used was 8e0aa76 (fixed, rest t=12), from a tree nobody had
named. It happened to be the right era, which is worse than wrong -- it agreed
with the pin by luck and one rebuild would have flipped it silently, and title_jp
differs by 74507 px between eras.

verify-screen now reads the reference CLI's pteff00 rest instant and compares it
against the export the port reads, refusing to score if they disagree. Controlled
both ways: passes with the matching binary, refuses the stale one built from my
own workspace.

And the pin is load-bearing, not an annoyance to revert: the workspace crate is
stale, so the pin is the only reason the export is correct. Consequence worth
stating -- my published branch carries the stale crate, so anyone building
sylpheed-cli from it gets the stale decoder.

8666c33a6a port: WITHDRAW the 'eras render identically' measurement -- I compared a binary with itself
Last iteration I overturned check-all's allowance on a measurement of 0 pixels
between the two decoder eras, and rewrote the tool's reason around it. The two
binaries had the same md5: one built in a worktree at formats-pin-2026-08-30 and
one from the workspace, and both commits carry the record-layout fix. I compared a
binary with itself and reported the zero as evidence. The 508-line diff I cited
was real and irrelevant -- it does not straddle the fix.

Done properly against origin/main, verified stale by the Decoder's own control
(rest t=70 vs rest t=12) and by differing md5s: title 0 px, main_menu 0 px,
title_jp 74507 px -- reproducing their figure exactly, under their flags and mine.
My second hypothesis, that --animated masked it, was also wrong.

What survives: the era still cannot explain this script's rows, for a fact I had
not established -- both sides of the comparison are the FIXED era, since a binary
built from the pin and one from the workspace have the same md5. Right answer,
wrong evidence. The note now carries its condition: title_jp is era-sensitive, so
if the reference is ever built from a different era than the pin, that row's cause
changes.

Twice now a correct conclusion has come through a broken experiment, and both
times the tell was two things that should differ producing identical output.

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
has nothing'.

ecd5e56e0c port: check-all excused two failing rows with a measurably false reason
The suite reported '2 DIFFERS, allowed: the pin is not on main, so this compares
two decoder eras', and I had quoted that for several iterations without testing
it. Built sylpheed-cli at formats-pin-2026-08-30 and at workspace HEAD and
rendered through both: title, title_jp and main_menu come out 0 pixels different,
despite 508 lines of difference in ui_layout.rs. The eras are not the cause, and
the allowance was excusing a real signal with a wrong explanation.

A second defect in the same eight lines: the expiry tested formats-pin-2026-08-29d
while Cargo.toml pins formats-pin-2026-08-30, so it would have expired on a tag
this tree does not use.

The real reasons are per-screen and already documented: title is the ptloop sweep
phase residual, title_jp is the --pose=rest sparkle handling -- where the port's
shipped pose scores +0.9994 against the game to the reference's +0.8727, so the
port is closer to the game on the row the script calls a disagreement.

Replaced with a named set: title and title_jp by name, any other DIFFERS fails.
A count cannot notice a different screen drifting while the total stays at two.
Controlled both directions -- passes on the known pair, fails on main_menu or
extras. The pin reminder now reads the tag out of Cargo.toml so it cannot drift.

72defd9552 port: check-all passes end to end; A and B transitions are not the same shape
First end-to-end pass I have actually seen: all six asserting checks ok, oracle
captures at 0.00-0.35%, verify-screen's 2 DIFFERS allowed for its stated reason.
My two earlier attempts produced nothing -- one killed by my own timeout with
block-buffered output, one wedged by the ffmpeg hang -- while I reported 'still
two lines, both ok' for three iterations. I was treating absence of output as
patience.

Their discriminating test holds, prediction written down first: incoming build 4
gives an 8-frame decay, build 5 a 5-frame one against my predicted 6. Their tell
reproduces from my export independently -- main_menu settled is [64], title's
opening pair is [255,64], composite [64,255,64], and no single element produces
it.

The consequence neither of us predicted: A title->menu is sequential with a real
~5-frame black interval, B menu->title has NO black interval -- the incoming title
draws at frame 34, before the outgoing quad ramps at 40. boot.gd applies
black_hold uniformly, so the port inserts ~9 units of black on B that the game
does not have.

Not changed. One run of one transition is exactly the generalisation they just
named as the error under two of their own wrong readings, and their second caution
is that the A figure may be a load rather than a designed hold. Recorded as a
known, stated divergence with a BLOCKED ask.

d508519b65 port: withdraw the 18-vs-19 agreement -- it compared two different intervals
The Decoder declined to let their measurement confirm my black_hold_units, and
they are right. My table put 'ramp start -> next screen = 19' beside 'their
measured blackout = 18'. Theirs runs content-start -> fully-black; mine runs
ramp-start -> next screen. Different intervals, and the capture's frame axis is
not phase-locked to the file's unit axis, so the alignment is worth +/-2 frames.

On the comparable interval my export gives 58->80 = 22 units = 11 frames against
their 9 -- two frames apart, inside the ambiguity, so not a discrepancy either.
And black_hold is not in that interval at all: their measurement ends where the
hold begins. It neither confirms nor refutes the 9.

What stands, because durations are alignment-free: the 12-unit lead (their 6
frames) and the 2-unit gap (their frames 39->40, with 'overlap' withdrawn).

9 now sits as authored-and-consistent, not confirmed-by-measurement.

Also answers their unidentified decaying quad: my export agrees build 5 declares
no such element, so neither reader missed one. Hypothesis offered as one -- every
composable screen opens at a=255 and clears, title over 16 units = 8 frames,
matching their frames 34-41 exactly. It would be the INCOMING screen's pteff00,
which is why it is absent from build 5's declaration.

6d4fe0d3b4 port: their withdrawn 14-unit hold does not touch my authored 9 -- it supports it
Two warnings. The first does not reach me: nothing is authored from
screen-transitions.md's 0.87/0.97/4.08 s spans, and nothing in this port reads
keyframe times outside the crate -- their stale fade_quads.py failure mode cannot
occur here by construction.

The second is about black_hold_units: 9. Testing their structural claim on my
export: pteff00 on main_menu is [0:a255 12:a0 70:a0 80:a255], rising to black over
70->80, while content fade-outs start at 58-60. That is 12 units of lead, exactly
six frames at 30 Hz, matching their measurement off the running game -- disc and
capture agreeing by independent routes. They say the two overlap; mine has a
2-unit gap, one frame, inside their stated resolution.

The arithmetic: quad ramp 10 units + my authored 9 = 19 units = 0.317 s against
their measured blackout of 18 units = 0.30 s. One unit apart, inside their own
resolution. The measurement that withdrew the 14 supports my 9.

It survived because I declined to author the 14 when the arithmetic was available
and fit -- I wrote that it was arithmetic rather than a measurement and left the
value where it had been measured. Had I adopted the composition I would now carry
24 units against a measured 18, which is the dead black they are warning about.

Not adjusting 9; one transition, one run, +/-1 frame.

67115f3141 port: audit my tree for the disc-wide ordinal foot-gun -- no exposure, verified
The Decoder found the ordinal/entry divergence is disc-wide (21 of 24 archives, 18
at ordinal 0) and that GP_TITLE is the mildest case on the disc, the only archive
whose first ten ordinals are the identity. That is luck, not design.

No exposure here, checked: the four archives they flag appear in flow.json with no
numbers at all, screen_names.json already says LOCATED BY ENTRY INDEX, and every
tool of mine passes --all.

Verified the high ordinals where GP_TITLE's identity would break first, since my
export addresses 13 and 14: publisher twins 10 vs 13 at RMSE 3.06, developer twins
11 vs 14 at 4.33, against a control of 47.91 for two genuinely different screens.
The addressing lands where HANDOFF says the entries are, and the control shows a
mismatch would have been caught.

The constraint is recorded for whoever exports those four archives; the absence of
exposure is a fact about what I have exported, not a property of the tooling.

Also corrects my own wording: I called ptlogo_all_eff a '50% glow'. What is
measured is the plateau -- that it is a glow rests on kind 0x3000 and a 200% scale
that nobody has put in front of the running game. The mid-ramp correction stands
on the numbers alone.

5c9a2a8f79 port: no case in the export separates width from mid-ramp, and my first answer was a bug
Width and mid-ramp predicted identically across my five capture-backed screens, so
I looked for a screen among the sixteen that breaks the tie -- either would turn
'confounded' into a minimal capture request.

The first run said title_jp was exactly that: window 46 with one mid-ramp element,
and I have the Decoder's capture of it. Wrong. The element is ptlogo_all_eff,
[0:a0 76:a0 112:a127 246:a127 258:a0], which HOLDS 127 from t=112 to t=246. My
test was 0<alpha<255, which counts any legitimately semi-transparent element as
mid-ramp, when the mechanism is about being caught in transition.

Corrected to: t falls strictly inside a segment whose endpoints differ. title_jp
goes to 0, main_menu and extras from 2 to 1 (pteff10 was a false positive
alongside the genuine ptmsg). The 5/5 result survives -- non-zero exactly where
the settle pose loses.

No separating case exists anywhere in the export: no wide window with a mid-ramp
element, no narrow window without one. The confound is structural across the whole
corpus, so no capture would separate the hypotheses from my side. They may be the
same phenomenon twice -- a narrow window is by construction one that closes while
things are still moving.

1c4bfeb86a port: verify my own indexing against the ordinal foot-gun that voided three of theirs
The Decoder retracted three claims: screen render --build N takes a build ordinal,
screen list maps [10] to entry 12, and the splashes are entries 10 and 11 -- so
their splash rows rendered the loading screens against splash captures. My own
HANDOFF entry had warned that this names the splashes as loading screens 'and
everything still validates'.

verify-screen's header claims --all protects me from exactly this, and a comment
claiming protection is what just failed on their side, so I measured it: my
reference for build 10 scores RMSE 8.97 against the publisher splash capture and
build 11 scores 8.77 against the developer one, with a cross-control (publisher
reference vs developer capture) at 48.17 -- 5.4x worse, so the discriminator has
teeth. The addressing is correct and now measured rather than asserted.

Worth the time because these two screens' 0.01% figures are among the strongest
evidence in the corpus and are cited in the rest() adjudication a proposal against
a pinned crate now rests on.

Their retraction confirms 190 and 145. Width and mid-ramp remain perfectly
confounded across every screen either of us has measured; my 5/5 predictor result
stands as a hypothesis about the mechanism, not as evidence over width.

a64afe1510 port: my predictor holds 5/5, but the evidence separating it from width does not
The Decoder concluded width does not predict settle-pose quality but my
transient-peak/late-arrival predictor does, on the grounds that the splashes are
narrower than the menu (window 8) and win by 75x.

The predictor holds 5 of 5 on my capture-backed screens: mid-ramp count is 2 on
exactly the two screens where settle loses and 0 on the three where it wins.

But their splash window disagrees with my export by 20x. Recomputed from raw
top-level keyframe times, publisher_logo is [0,15,30,45,235,239,251,255] whose
widest gap is 45->235 = 190; developer_logos gives 145. We agree exactly on title
(76) and main_menu (12), so the divergence is specific to the splashes.

Consequence: the splashes are the WIDEST of my five, not the narrowest, so width
and mid-ramp predict identically and are perfectly confounded across my screens.
The case that separated them evaporates -- my predictor is not established as
better than width by this evidence, which is a different claim from being wrong.

My numbers also make their own census coherent: at window 8 the splashes would sit
in the 40.9% bucket while showing zero mid-ramp elements, a paradox; at 190/145
they sit in the wide bucket where zero is what the census predicts.

8dc22e2931 port: the settle-instant candidate is not uniformly better -- the menus arrive late
Their symmetry-breaking property is testable on the two screens my earlier table
marked confounded, and it turns up a class where their candidate loses.

ptmsg is [0:a0 44:a0 56:a255 58:a255 64:a0] and main_menu's settle window is
[44,56] with instant 50 -- so the footer is at alpha 127.5, half-drawn, at the
instant their candidate poses everything. Same on extras. The settle instant is
the midpoint of the longest keyframe-free interval, and on both menus that
interval ends exactly as the footer starts to arrive.

Measured with focus absent from both sides so the earlier confound cancels: t=50
gives 0.30% differing, t=58 (the footer's own hold) gives 0.25%.

Small and real. It does not overturn the proposal, which wins 9x-75x where rest()
returns a transient's peak. It identifies a failure mode of its own: an element
arriving after the settle window closes is caught mid-fade. Both poses are
approximations to a settled screen; neither is the settled screen.

Also: my first run asked --time=50 meaning units and got 50 SECONDS, past the end
of everything. Both poses returned RMSE 56.02 / 9.15%, identical to two decimals,
which is what made me look -- two different inputs giving the same output is the
instrument saying it ignored the input.

069589ac79 port: score the boot's own end frame against the game -- 0.00% differing
--boot --capture= used to write no file: _finish_boot() was reachable only from
the overlay-quit branch, and the boot quit first because that branch fires when
_overlay_spec.is_empty(), which it is the instant the overlay is raised. Fixed
earlier this session by the _overlay_quit_at guard -- and I never went back to
check what the fix made possible. The P3/P7 artifact has been available for hours
and unused.

The boot running unattended and photographing its own end state: RMSE 12.80,
0.00% differing against live-title-press-a.png. The residual is the known capture
gamma floor.

More useful: verify-capture reaches this frame by a shortcut (--screen=title
--overlay=press_start --time=3.95) rather than by booting, and that shortcut has
been trusted since it was written and never tested against what it stands in for.
It is faithful -- 12.83 / 0.00% against the boot path's 12.80 / 0.00%, agreeing to
0.03 RMSE.

Does not show the intervening sequence is right: it is one frame, the last one.

76961600bd port: adjudicate the rest() replacement against the game -- 3 clean wins, 2 confounded
They proposed posing at the screen's settle instant, found their control could not
validate it (a candidate cannot be adjudicated against the incumbent it replaces),
and said the oracle number decides. I had only run it on one screen.

Three screens adjudicate cleanly and all favour the candidate: title 0.21% vs
1.82%, publisher_logo 0.01% vs 0.75%, developer_logos 0.01% vs 0.33%. The settled
figures match verify-capture's independently recorded numbers to the digit.

Two rows are not evidence. My first table had main_menu at 3.29% for the
candidate, losing by 13x -- the opposite direction from everything else, with no
plausible story. --screen= shoots immediately, so that render drew 6 of 16
elements and skipped ptframe1, ptframe2 and ptmsg as transparent at t=9. The same
wrong-frame error as title_jp, caught before publishing only because the
direction made no sense.

Posing them properly needs --menu, which also draws the focus record, while the
rest column draws none. verify-capture's header records main_menu without focus at
2159 px = 0.234%, and my incumbent figure is 0.25% -- so the entire gap on those
two rows is the focus record, not the pose. Marked confounded rather than counted;
a 5-0 was available by not looking.

Does not validate their implementation: I tested the port's settled pose, not
UiBuild::settle_time().

d18fc5d71e port: test the Decoder's structural criterion on my census -- it fails my control
Their surviving number needs no threshold: the dwell fallback runs only when no
two adjacent poses are equal, so every pose it returns is un-held by construction.
The obvious move was to replace my 'gone before 60% of the screen' cutoff with how
long the rest pose is held.

It flags ptmsg (the main menu's footer, 2 units of 80) and ptbtn00 (the plate, 2
of 244) alongside the real sparkle (2 of 269). All three sit on a 2-unit plateau,
so hold duration cannot separate them -- and the two it gets wrong are the exact
pair whose absurdity caught my first census.

The criterion does not transfer because on the fallback path nothing is held, so
un-held IS the defect, while on the plateau path the plateau is real and what
distinguishes a footer from a sparkle is where it sits relative to the screen's
end. The screen-span criterion stays.

a43dee3ab0 port: the loading screens are no longer black -- it was the paint order
verify-screen's header has said since P1 that build_12/build_15 render pure black
in both renderers, with an open question whether that was the port's bug or the
decoders' reading of rest. Measured today: max 214.5 on both sides, mean 1.949
port against 1.918 reference. Not blank, and they agree.

It was the paint order. My own earlier measurement had already answered it and I
had not connected them: removing the forced-backdrop pass makes the first element
pgloading_loop5 and the black screen returns. pgloading_eff00 carries layer: null,
layer_source: none -- the only elements in the export with neither a read nor an
implied key -- so its position rests entirely on the occlusion constraint.

The guard stays, with the stale paragraph kept as history. It was right when
written, and a guard that stops firing is the kind that rots out of a tool.

Refutation attempt on the Decoder's census scope: my six transient
ptlogo_back2eff* on title are also GP_TITLE, so if they were fallback fires their
count of four would be wrong. Their claim survives -- all six reach rest by the
plateau path, alpha 255->255 with identical pos and scale, so the fallback never
runs. The two censuses differ in scope, not in fact.

9b30fdb279 port: accept the plateau correction, and census my own rest-transient exposure
The Decoder refuted my refinement: palogo_gamearts_eff/palogo_seta_eff hold a=255
at identical x, y and scale from t=15 to t=30, so that is a genuine plateau,
rest_plateau() handles it, and t=15 is correct for that path. They are not among
their four.

The consequence strengthens the rule rather than retracting it: my rest pose for
them really is the flash's peak, reached by the SOUND path -- so 'a rest render is
not a frame to score against a capture' does not depend on the fallback being
unsound. A plateau can itself be the held peak of a transient, and their census
understates exposure rather than bounding it.

Censused my own tree. The first answer, 28 elements across 12 screens, was wrong:
it counted the screen's exit ramp as the end of visibility, so ptmsg -- the main
menu's own footer -- and ptbtn00, the plate, came back as transients. No control
would have caught that; the arithmetic was right. What caught it was saying what
the number meant physically.

Re-keyed on the screen's span: 31 elements across 8 of 16 screens, all of them
eff/loop sparkles or the two loading screens, with ptmsg and ptbtn00 falling out
on their own. Exposure is twice what the splash finding suggested. None of it
reaches shipped output.

955f5b0c02 port: the rest() flash defect reaches all four splashes I ship; the port survives it
The Decoder censused rest()'s dwell fallback from the file side: 2305 elements
have no plateau, 1697 of those get a visible pose, and in GP_TITLE all four
visible fires are on the splash screens this port ships. Confirmed in my export.

Refinement to their description: they named the [0:a0 15:a255 30:a212 45:a0]
shape, but palogo_gamearts_eff and palogo_seta_eff hold 255 through t=30, so
their fallback lands on the flash PEAK rather than its decay. Same defect, worse
pose.

The port ships the right frame and there is now a number for it. Publisher splash
against the committed oracle capture: timeline (shipped) RMSE 2.17 / 0.01%
differing; --pose=rest 9.05 / 0.75% -- 75x the differing area on a screen I ship.
So the rule added to verify-screen's header after the title_jp mistake
generalises, and is demonstrated against an oracle rather than argued.

What did need fixing: ScreenView logged '(transparent at rest)' for every skipped
element whatever instant it posed, so it said that about palogo_sqex_eff, whose
resting alpha is 212. That is the same rest-versus-posed-instant confusion that
cost a wrong conclusion, pre-printed in the log. It now names the instant.
Controlled both ways: timeline says 'at t=6' and skips the flash, --pose=rest
still says 'at rest' and draws it.

835acf930e port: WITHDRAW the claim that the port drifted away from the game -- wrong frame
The previous entry scored verify-screen's title_jp frame against the oracle and
concluded the port had moved away from the game. That frame is posed --pose=rest,
which the port does not ship. Posed as it runs, the disputed block scores +0.9994
against the reference's +0.8727, and the whole surface +0.9652 against +0.9200 --
holding under gamma compensation and on the English control (+0.9946 vs +0.9560).
The port is closer to the game than the reference on both title screens.

Mechanism: ptlogo_back2eff1 is (0,0)(98,0)(100,255)(102,255)(104,0) -- a 4-unit
sparkle whose rest.t is the peak of its own flash. Six of them stagger across the
logo, so --pose=rest fires every sparkle at once. The 25.6% excess light was real
and was in a frame nobody sees.

verify-screen is not at fault: it poses rest deliberately, so that both renderers
read one decoder and the run is a consistency check. I used a consistency-check
frame for a correctness question. Its header now says its frames must never be
scored against a capture.

A second claim in that entry was also wrong -- both screens draw those layers
under pose=rest; I had compared a --menu timeline log against a verify-screen
rest log and read a mode difference as a screen difference.

verify-capture takes a fifth per-row field, a capture crop, because this capture
is a full display frame with the surface at +0+45 while the others are
pre-cropped. With it title_jp reads RMSE 20.91 / 1.04%, beside title's 14.16 /
0.21%. The row prints 'no capture' until their branch merges.

11dcb3b2a3 port: the JP title capture adjudicates title_jp, and it goes against the port
The Decoder captured the Japanese title at rest (310bf86) without comparing it to
either renderer, keeping my diff independent.

Alignment recovered, not inherited: row/column profile correlation with the
English pair as control gives (0,0) for the control and dy=-45 for the JP frame --
their stated offset, measured. My first look said 'no letterbox, content spans all
720 rows', which was true and irrelevant.

The instrument is fair: on a control strip where both renderers agree they tie
(r 0.9751 vs 0.9756). In the disputed 350x396 block at (405,74) the REFERENCE is
closer -- r +0.8727 against the port's +0.7462 -- and the verdict is stable under
gamma compensation at both measured title gammas. The port puts light on 25.6% of
the block the capture does not have, against the reference's 15.9%.

This is the opposite of what I expected: the burst the Decoder describes IS
there, and the port draws more of it than the game does. A qualitative match on
'is the effect present' was about to stand in for a measurement of how much.

Not settled: which change did it. Both render at rest t=10 so the settle window is
not in play; four commits touched that path and I have not bisected them.

title_jp's DIFFERS is now known to be the port's -- the first baseline row whose
direction has been established against a capture.

8ae0ec2287 port: verify-screen was nondeterministic; pin the pulse phase in the harness
Running the full set after the plate fix, press_start returned over3 5021, 8919,
5021 on three identical runs. The plate's looping focus record takes its phase
from time_units, which free-runs, so the captured frame lands wherever the grab
fell -- while the reference renderer cannot pulse at all.

The port is not the thing that is wrong: the pulse is measured and a thing that
pulses does not stop because the screen arrived. ScreenView.loop_phase_units pins
it, negative means free-running and stays the default everywhere, and only the
harness passes --loop-phase=0.

Controlled: pinned, 3 runs identical; free-running, 3 of 4 identical and one
different. That 3-of-4 is why it survived -- it looks deterministic most of the
time, and without the negative control a no-op flag would have been
indistinguishable from a fix.

With the phase pinned press_start reads max 1 / over3 0 OK -- the recorded
baseline exactly. Fifteen of sixteen rows now match.

The sixteenth, title_jp, has genuinely drifted: 155/20498 -> 233/61208,
deterministic, on the Godot side, localized to one 350x396 block at (405,74).
There is no capture of the Japanese title, so I can say the renderers moved apart
but not which moved. Recorded as an ask, not resolved.

b9667c6c9a port: the PRESS A plate comes back after B, and it did not here
The Decoder measured that after B from the menu the plate is re-drawn (daf8f47).
The port landed on a BARE title: _menu_arrive drops the overlay -- correct, the
plate goes with the screen it was measured on -- but nothing put it back, since
_overlay_spec is cleared the instant the overlay is raised and only the boot
sequence ever set it. Confirmed by running it: ten title elements, no ptbtn00.

_rearm_overlay_for reads the declaration out of authored/flow.json's boot step
for that screen rather than naming press_start, so the plate returns by the same
path and shared clock as on boot, with NO new constant. Controlled both ways:
cancel raises it, entering EXTRAS (no overlay declared) raises nothing.

Script steps now carry an elapsed timestamp, without which the port's own press
latency could not be compared to a measured one. With it: B at 1.01 s, title at
1.37 s = 0.36 s, against their measured <= 0.4 s -- nothing was fitted to that.

The plate's RETURN time does not agree: 4.33 s here against their 7.3 s to pulse,
of which up to 2 s is pulse-detection phase. Not adjusted -- an authored delay in
this same block was already refuted once. Recorded as an ask.
