Last iteration I proposed that the two sweeps share one indices=8 draw
because ptloop01 links to ptloop02, and said testing it needed a
loading-screen capture I lack. Wrong twice: a linked pair was already in
every capture, ptbtn00 -> ptbtn00f.
Measured: ptbtn00f is drawn ALONE in 899 (f6b) and 1441 (f6) draws and
batched in ZERO, while the sweeps pair up in 1092 and 1744. Linkage does not
batch. The constraint is blend state -- ptbtn00f is additive and its linked
partner alpha-over, which cannot share a draw. The sweeps batch because both
are additive on one page.
Page+blend is necessary but not sufficient: 8154/alpha-over appears as two
separate draws in a single frame, 2108 such draws in f6b. This removes a
wrong cause rather than supplying a batching rule.
Extends read_draws.py to preserve draw grouping (draw index and quad count
per draw); check_labels.py still passes unchanged as a regression control.
Refutation attempt on the port's 0x3002/0x3003 menu-item reading: survives.
958 of 970 stems contain "btn"; the 12 exceptions are psselect_slot and
psselect_slot_blank, which are menu rows.

Adds examples/element_records.rs, which lists leaf AND focus_link records
for an element, plus a disc-wide census. Built because I claimed alpha 80
was undeclared after reading one of ptbtn00's two records -- and focus_link
was already parsed, with ui_layout.rs:424 already documenting the focus
record. The format was known and I did not consult it.
Census: 1467 of 15493 elements (9.5%) across 815 builds carry a second
record whose keyframes are invisible to a by-name leaf lookup.
Refutes our own parser's description of the field. It is documented as "the
focused state of a button", but GP_TITLE has pgloading_loop1 -> loop3 ->
loop4, a chain of three loop animations, and ptloop01 -> ptloop02, the two
sweeps. Neither is a focused state. Naming defect only -- behaviour is right
where it is read -- so not renamed here.
🟡 Notes a better candidate for why the two sweeps share one indices=8 draw:
they are linked, not merely co-textured. Testable on the pgloading chain,
which needs a loading-screen capture I do not have. Named, not claimed.

I claimed ptbtn00f's peak alpha of 80 was capture-only and refuted the
port's audit with it. Verified on the disc myself: ptbtn00f.rat, loop 120,
eight keyframes 0:0 6:6 29:74 35:80 50:80 58:74 97:6 105:0. ptbtn00 carries
TWO child records -- the leaf ptbtn00.rat (flat 255, which I read and
described correctly) and the focus record ptbtn00f.rat, which holds the
pulse. My "nothing declares 80" said only that nothing reached my
enumeration. METHOD.md has five entries on exactly this class.
Resolves the 🟡 with it: the corpus line attributing the 120-unit loop to
ptbtn00f is correct as written.
Turns the retraction into a stronger check. The amplitude is declared, so
check_labels.py now verifies the SHAPE: mean |alpha| error 1.14 levels (f6)
and 0.35 (f6b) against the declared 8-key curve. The first version assumed
the onset frame was t=0 and f6b FAILED at 3.24; the fix was aligning by
content rather than loosening the tolerance, since the 6->74 segment climbs
~6 levels per frame. Best lag is ~1 frame in both runs -- the element is not
drawn while its curve sits at alpha 0.

Three of my errors were the label rather than the measurement, and a
correction in one document did not reach the next page I wrote. The port
built check-authored-vs-declared for values the disc can arbitrate and named
the gap: capture-only values that name an element rest entirely on my label.
check_labels.py closes that for the cases where the identification was
itself made by matching a declared quantity -- 8 checks over two captures,
all passing, with a --selftest that points the plate label at ptcopyright
(the real error) and must fail. It does, at 82-83% against a 5% tolerance,
with the other checks still passing so the failure is localised.
Refutation of the port's "all five figures are also declared": lands for
one. ptbtn00f's peak alpha of 80 is not declared anywhere -- ptbtn00.rat's
parent peaks at 255 and its leaf is one keyframe at 255 flat, with the
120-unit loop declared but no amplitude. The period checks out; the
amplitude is capture-only and their check cannot see it.
Opens a 🟡 not mine originally: the corpus attributes the 120-unit loop to
ptbtn00f, but it belongs to ptbtn00.rat whose leaf is ptbtn00.t32. Left
uncorrected since the identification rests on the period, which holds under
either name.

The F6 page measured the sweep-to-plate separation against ptcopyright and
called it the plate. I had already established, on another page, that
ptcopyright is NOT the plate -- ptbtn00f is. Against the real plate the lead
is 83 and 165 frames, i.e. 0.138 and 0.141 of a sweep loop (2.2% apart),
against the 0.057 I published and sent to the port.
The conclusion is unchanged and stronger: with no input the glow precedes
the plate by 2.4x more than reported, and with A it still collapses to
essentially zero (-1 frame). Gating the sweep on the plate is a worse fit
than I made it sound.
Third instance of a label being the error rather than the measurement, and
this one is the same label I had already corrected elsewhere -- the
correction did not propagate to a page written after it.

The brief asks for two routes and I had only run the capture. This runs the
code route far enough to record an honest failure: the title's phase 2 and 3
handlers dispatch through vtables on nearly every branch, so finding the
clock write statically needs indirect-call resolution this container does
not do cheaply.
What the scan does establish: over 0x821C4000-0x821CD000 there is no
`li rN,<v>` for any v in 160..250, against a control of 684 li instructions
in the same range. So the snap target is computed or data-derived, not a
literal in the title's code.
Refutation aimed at my own capture result: a literal would have NAMED the
target and refuted "unpinnable from any capture". None exists, so that claim
survives and gains a second reason.
Names the instrument that would settle it: a write-watch on the clock field
in Canary, which would also close "which function advances the clock".

The refutation aimed at the port did not land -- they already run two
timelines, measured on their side (72.6/552.6 against declared 73/553 over
17748 samples), the right instrument for a question about their own
renderer. Recorded as an attempt that failed; still worth making, since they
report they would otherwise have asserted it from the code.
Also notes in METHOD.md that the batched-draw trap produced a THIRD wrong
finding with the entry already written. Two sections of that file and a
REFUTED.md line already said a draw carries more than one quad. The lesson
is not the fact but that a reader written before consulting the file
reproduces the bug the file exists to prevent.

Pre-registered 1.2000 from the declared leaf loops before measuring.
Measured 1.1967 (0.28%) in f6b and 1.1841 (1.33%) in f6, as a ratio inside
each capture so no clock enters -- which is why runs differing 2x in frames
agree. f6b happens to pace at one frame per leaf unit: 600 frames for 600
declared units, 718 for 720.
First test pteff03a's declared timeline has ever had. It could have failed
against me: the flattering reading of unit 11's batched draw is one
traveller driving both quads, which gives equal periods. It does not.
Also closes "one wrap per capture, period not obtained", which has been open
all week -- both leaves give a complete boundary-to-boundary cycle in both
existing logs. The truncating reader saw one quad, so it could see only one
of the four cycles already on disk.
Refutation aimed at the port: running both leaves at one rate leaves the
strips locked and drifting ~118 units per cycle from the game.

pteff03a's declared timeline has never been checked against a capture. The
leaves declare 600 and 720 units, so the periods must differ by 1.200 within
a single capture. Equal periods is the flattering-but-wrong outcome the

The port is blocked on what 0x3003 is, having only 0x3002 in its menu-item
rule. The two differ in bit 0 alone. Disc-wide over every .pak: kind&1 ==
has_parent agrees on 15493 elements with 0 counterexamples -- 192/192 for
0x3003, 778/778 for 0x3002, and the same for every other kind. The flag is
exactly redundant with the +32 parent field.
So the bit that differs carries no role information: 0x3003 is a 0x3002
button record that is parented. That replaces the port's circumstantial case
with the field, which is what they asked for rather than a widened rule.
Flags what this does NOT license: it is not a decode of "is a menu item",
and 0x73002/0x73003 (160 elements) carry an undecoded 0x70000 that any
mask-based rule silently decides about.

The brief asked which of two declared events the human sees. Neither. With no
input the sweep pair enters 34 frames (f6b) and 67 frames (f6) before
ptcopyright -- 0.057 of a sweep loop in both, agreeing to 1.2% across runs
that differ 2x in frames. With A pressed during the build-in the separation
is 2 frames.
A reveals the plate and restarts both sweep leaves at t=0 in the same frame,
so a player who presses A sees them start together and reports exactly that.
The control that makes it an explanation: in the late-press run A landed
after the sweep had already started naturally and the two are 29 frames
apart -- same input, opposite result, decided by when the press falls.
Consequence for the port: do NOT start the sweep with the plate. That fits
one boot and breaks the other. The declared gate plus the snap restarting
leaves produces both observations with nothing authored.
Refutation attempt: looked for a case where the port's current behaviour
fails against these four captures; found none.

ptcopyright goes absent -> 255 in one frame at the snap, skipping its
declared 138->160 ramp, so t>=160; the sweeps are still at 255 so t<238.
Its identification is measured: in the control it first draws at t~143 and
reaches 255 at t~164 against a declared 138->160.
It stops there for a reason worth recording. Every build-4 element with a
key past t=100 holds a constant pose across [160,238) -- their intersection
is exactly that window -- so the game draws a bit-identical frame at t=160
and t=236.
Refutation attempt on the port's 236.0: not merely survives, it can never be
confirmed or refuted by capture. Every value in the window is
observationally identical, and it stays that way because the clock freezes
at settle and the exit ramp plays on leave rather than on a timer.
Classified undecodable-with-reach so nobody spends another run on it.

Pulse ratio HOLDS: 0.1000 (f6b, 16 clean cycles) and 0.0993 (f6). 60 leaf
units = 120 title units = ptbtn00f's declared loop. The independent leg
under leaf/title = 0.5 stands.
Unit 10's conclusion survives but MY NUMBERS WERE WRONG. I quoted
254.0-256.9 / 253.9-254.9 as the implied parent's range; those were the rows
I had printed, every 20th frame, not the series. Real first-cycle figures
are 250.9-260.5 (f6, n=1128) and 253.1-255.0 (f6b, n=560).
Post-wrap the spread widens to 237-283, but only in f6 -- the run with
dropped frames -- while f6b holds at median 254.3. That is my linear phase
model drifting, not the parent varying; a parent that varied would degrade
in both.

Last iteration I asserted F5 was unaffected by the truncating-reader bug
because it compared like with like. Asserting that is the move that produced
the bug, so this measures it. The new reader sees 9.7 quads/frame vs ~7.5.
Scalar that needs no element identification: quads mid-ramp (0<a<250) per
frame goes 6,4,4,4,2,1,4,3 -> 0 at f436, while the control never reaches 0
anywhere in 48 frames of build-in. One frame with nothing part-way through a
ramp is the cut.
Bonus the old reader could not show: both sweeps enter at f436-438 at their
declared opening alphas -- pteff03 at 255, pteff03a at 1,2,3,4,6,11,17 from
its declared 0.

The two sweeps are batched into ONE additive indices=8 draw, two quads, and
my parser took the first v: match per line and discarded the rest. Every
analysis saw quad A and never quad B. No new capture was needed -- the same
logs units 5 and 6 used already contained it.
Both strips measured: opposite directions matching the declared -639->1521
and 1721->-839, and a size ratio of 1.301 against the declared sy ratio
800/600 = 1.333.
Unit 5 recorded that the PORT's renderer draws pteff03a and treated that as
the port being wrong. The port was right.
Third instance of this class in the corpus (palogo_anima and the six-quad
dump are the others): a truncating reader yields a clean, complete-looking
negative. Reading one raw draw line in full would have caught it -- indices=8
was printed on every line and says two quads outright.

Phase-free: the pulse is exactly 1/10 of the sweep's 600-unit loop -- f6b
gives 60.0 frames over 16 cycles with zero variance against a 600-frame
sweep. 60 leaf units x the independently measured leaf/title = 0.5 gives 120
title units, ptbtn00f's declared loop exactly. That is also a third
independent route to the 0.5 ratio, from an unrelated declared quantity.
And it resolves the conflict I have been flagging on three pages. The quad I
called "the plate" at x=-0.54 is ptcopyright: its fade-in is 21-22 title
units under both agreeing calibrations, matching ptcopyright's declared
22-unit ramp, not the plate's 12. The plate is the pulsing element. Two
elements, one label, and I checked the label -- there was never a clock
conflict. Retires the 🟡 on every title-unit figure across three pages.

The pre-registered wider test refuted my own claim. Pressing A at the
sweep's gate instead of 40 frames later leaves ~40 frames of artwork
animating: three elements mid-fade-in vanish in one frame and the settled
set appears at 255. The sweep enters at 255 with NO ramp where the control
ramps it 17->255 over ~15 frames, so the title clock jumped past t=100 --
and not past 250, since ptloop01's exit would have hidden the sweep.
So clock:"shared" is NOT refuted. I told the port the opposite and must
correct it.
Cause: the press takes 11-12 frames to take effect (f445->f456, f424->f436)
and my 5-frame artwork window sat entirely inside that gap. It matched the
control because the input had not been acted on yet. The window was not just
short, it was positioned where the effect cannot appear.

Three captures, aligned by the sweep's position rather than by frame number.
The plate's alpha goes 23,46,69,92,115,139 over ~11 frames with no input,
and 255 in a single frame when A is pressed: zero intermediate values
against eleven. A cuts, it does not accelerate -- the human's prior holds.
The control is what makes it readable. Four elements ramp out right around
the press and I could have reported that as the effect; at sweep x=-1.42 all
three runs agree quad for quad, so those exits are the ordinary build-in.
Refutes clock:"shared" on F4's own discriminator: the artwork keeps
animating across the press, frame for frame identical to the control. Reach
stated -- that half rests on a 5-frame window, since everything else on
screen is already at 255 and cannot discriminate.
Also records the first attempt's miss: blind wall-clock timing put the press
after the settle, where A is accepted instead. The probe now gates on the
sweep appearing, which is the parent's declared t=70..100 gate.

Build 4 declares ptloop01/02 alpha 0 until t=70, full at t=100, with 238..250
an EXIT ramp -- which answers the brief's "is 238..250 an entry or an exit"
for these elements. Builds 5/6 declare the same records flat 255, so the
build must be named before the question has an answer.
Control ran in the direction that could have flattered the hypothesis and
did not: the leaf's own alpha FALLS 255->128 where the capture RISES 8->255.
Decomposing against the leaf's declared curve leaves an implied parent that
pins at 255.0 +/-1.5 across hundreds of frames while the drawn alpha swings
242->132->145. Parent alpha is multiplied in; closes that standing 🟡.
Restores unit 8's 0.514: leaf/title = 0.4795 and 0.4667 across two runs that

The port challenged two statements of mine as mutually inconsistent and
refused to guess which I meant. They were right to. Answering with the
clock-free quantity they proposed:
(onset - title start) / (plate - title start) = 0.489 / 0.507 (3.7% apart)
So the onset is at the MIDPOINT. That refutes the port's implemented 0.2 and
my own summary's "shortly before the plate" (~0.85) alike.
Root cause of my error: the ratio measurement was right, but I converted it
to title units through the plate's declared 12-unit ramp and wrote the
summary from the conversion. That calibration makes title-start..plate 75
units where the data declares the plate at t=238 -- 3.2x out, not the 1.75x
this page reported. All title-unit figures withdrawn; the ratios never

Two captures of the same animation disagree on frame counts by 1.947x, so
frames are not comparable across runs. Expressed as ratios to a long
in-capture baseline, both runs agree: loop period = 13.93 baselines (0.35%
apart), and the sweep starts 0.79-0.80 baselines BEFORE the plate (0.9%).
This answers F6: the sweep does not start at t=0 as the port has it, nor
exactly with the plate -- it leads the plate by about 40 title units, under
a second, which is consistent with what the human reported seeing.
Surfaces a conflict rather than smoothing it: unit 8's title rate of 1.0
units/frame (from ptcopyright) and the plate's 0.571 units/frame are 1.75x
apart in the SAME capture. Either an element's declared ramp is misread or
the two are not on one clock -- the port's clock:"shared" premise. The
ratios stand without a clock; the title-unit conversions are 🟡 pending F4.

Unit 8's rate (0.514 units/frame) rests on one wrap, a start-to-wrap span
rather than a period. Hardening it needs a longer capture with two or more
wraps. Two attempts, both failed on the harness rather than the game.
First launch never started: the pgrep && echo || { } guard took the wrong
branch, no output directory was created and no process ran, while a stale
emulator from the previous iteration was still up. It looked like a running
capture for several minutes.
Second launch started, armed, pressed A and wrote no draw log at all --
canary.stdout stayed at 0 bytes and no xenia_re_ui_draws log appeared,
despite the script printing "armed at 8s". Likely a race with the orphaned
emulator from the first failure, not confirmed.
Unit 8's numbers are unaffected; they came from the intact f6 capture,
which is still on disk. The offset has two independent supports; the rate
still rests on a single wrap and the port should not ship on it.
The lesson, and it is the second harness failure of this shape: "armed at
8s" printed while nothing was being logged. The arming step reports success
on SENDING the keystroke, not on the logger responding -- the same silent
failure that cost the first F1 probe a run, which I "fixed" by making the
window lookup fatal. That fix was too narrow: the window was found, the key
was sent, and the log still never appeared. The check that would have
caught both is to wait for the draw log to exist and be non-empty after
arming, and abort loudly otherwise. A probe that cannot confirm its own
instrument is recording is a probe whose negatives mean nothing, and I have
now written that bug twice.

The two numbers the port asked for, both from one capture so nothing
crosses runs.
Title rate, which unit 4 flagged as an assumption and is now measured:
ptcopyright declares alpha 0->255 across t=138..160, 22 units, and the
rising run is 22 frames. So 1.0000 title units per frame, with the step
agreeing independently (255/22 = 11.6 against a measured modal 12). That
also confirms the splash's 1 unit/present on a second screen, which it had
never been checked against.
Leaf rate, anchored on the wrap rather than the endpoint: first drawn at
frame 746, wraps at 1914, so 1168 frames for the declared 600-unit loop =
0.5137 units/frame. This SUPERSEDES unit 3's 0.463, which divided 540 units
by 1167 frames -- but the declared track is stationary from t=540 to t=600,
so that endpoint is where motion stops, not where the loop ends.
So: offset +40 title units (confirmed, and the title rate being 1.000 makes
frames and units interchangeable there), rate 0.514x the title's, within 3%
of exactly one half. leaf_t = 0.514 x (title_t - 40).
Flagging rather than smoothing, as they asked: the port runs the leaf
unscaled at 1.0x where this measures 0.514x, so their sweep should cross
twice too fast -- which a viewer ought to notice alongside the early start,
yet the human reports the animation looks correct. Either "looks correct"
is about the effect rather than its speed, or one of the two measurements
is wrong. My rate rests on a single wrap; a longer title capture giving a
wrap-to-wrap period would settle it.

The port raised a real caveat: my earlier scans filtered on height (>1.2
NDC) and sample count (>=20), so a population of many small lights would
have been invisible to both by construction. Dropping both filters, over
the whole title era: 59 distinct shapes, 2 moving, 57 static, and ZERO
small moving shapes. The two moving keys are the rounding-split halves of
one element, pteff03.
So there is exactly one moving quad on the title, 883x1134 px.
That answers the human's actual uncertainty -- whether the game renders one
light per line or one light covering several close lines. It is the second:
the multiple lights are painted INTO the texture of a single large sweeping
sprite, not drawn as separate moving objects. A port reproducing "several
lights" as several elements would be modelling the wrong thing.
The port's caveat was right to raise and the check excludes the population
it warned about -- third time in this exchange that asking was worth it
even when the specific worry did not apply.
What I have NOT done, and it was the literal ask: the human asked for
screenshots and I have taken none. I answered the counting question from
the draw stream because it is the stronger instrument for how-many and
how-big -- it reads the guest's vertex buffer rather than pixels and cannot
miss a faint light. But "what do the lights look like" is a question about
an image and the draw stream cannot answer it. That remains open.
Reach: one boot, one window, every quad in the stream. Static elements are
not counted as lights -- 57 exist and some may pulse in place; this unit
counts motion, not brightness.

Unit 5 filtered on height, so a collapsed quad would have been invisible to
it by construction. Dropping that filter: across the whole title era,
frames >=700, every quad regardless of size --
RIGHT->LEFT travellers (pteff03a's direction): 0
LEFT->RIGHT travellers: 2 (both pteff03)
static shapes: 10
degenerate/collapsed quads: 0
Not one quad travels right-to-left in the entire title era at any size, and
nothing is submitted collapsed. So pteff03a is absent from the draw stream
-- not drawn invisibly, not drawn at zero scale. That strengthens unit 5
from "no tall quad of that size" to "no quad of that motion at all".
All three candidate mechanisms are now dead: the zero-alpha skip is weak on
its own terms (explains opening frames, not a whole run), the focus/variant
link was eliminated by the port's wider survey (linked targets chain across
unrelated element kinds -- on one menu a sweep points at a button, so the
field is a chain pointer rather than a variant selector), and collapsed
scale dies here.
Recording that as the state rather than proposing a fourth candidate.
Three have been named and three have failed, two by checks that took
minutes. A fourth guess before the human's "one streak or two" look would
be guessing against an answer about to arrive for free.

Every quad taller than 1.2 NDC in the whole capture, frames 1..2499:
h=3.15 travelling left-to-right over 1754 samples (pteff03), and h=2.00
static for 54 frames (not a sweep). Nothing in pteff03a's expected band
above 3.4, and only one travelling quad in the capture at all.
pteff03a declares 800% scale against pteff03's 600%, so its AABB is ~1303
px ~ 3.62 NDC, travelling right-to-left. It is absent.
Not a windowing artefact: ptloop02's leaf reaches alpha 128 at its t=150,
which at the unit-3 leaf rate is ~324 frames after its start, well inside
the 1754 frames captured.
For the port: their renderer draws pteff03a, confirmed on their side at
three instants. An extra light streak the game never shows, appearing
partway through the build-in, looks exactly like "the sweep starts too
early" -- and unlike the alpha question it does not depend on unit 2.
One capture, one boot, one window. The scan was over every tall quad in the
whole stream rather than a filtered subset, so the absence is strong, but
it is still absence in one observation. The five-second human check the
port is arranging (one streak or two) settles it faster than another
capture and should come before anyone deletes an element.
The disc declares ptloop02.rat as element 12 beside ptloop01.rat as 11,
identical pivots and keyframe times, so why one is submitted and not the
other moves to my side. Untested candidates: its leaf alpha starts at 0
where pteff03's starts at 255; or a focus/variant link means only one of
the pair is ever active.
Refutation: the port's own challenge to my by-size identification -- that
both sprites are byte-identical in size -- they withdrew themselves and
correctly. The sprites are both 399x180 but the LEAVES declare different
scales, so the drawn quads differ by a third in height. Second time in this
exchange a challenge was right to raise and wrong in its stated reason, and
both times the check still found something real. The value was in asking.

Same capture, counts only. Title's first drawn element is frame 706; the
sweep is first submitted at 746 and first ON SCREEN at 747, so +41 frames.
For scale, the plate's declared t=236 is frame ~942 at 1 unit/present --
195 frames after the sweep is already visible geometrically.
Named rather than folded in: that comparison assumes the title's first
drawn frame is its t=0 and that its clock runs at 1 unit/present. The 41 is
a raw frame count and carries neither.
What it settles: POSITION does not gate the sweep late. So if a human sees
it start when the plate appears, the gate cannot be where the quad is -- it
has to be how opaque it is. That puts the whole of F6 on unit 2, which is
amber: does the parent's alpha multiply into the leaf? The parent ramps
0->255 across t=70..100, so if it multiplies the sweep is invisible until
~70 and dim to 100 (a real early gate); if it does not, the sweep is fully
lit from +41 frames and the human's report has no mechanism yet.
The disagreement has narrowed usefully: before this unit "starts when the
plate appears" had two candidate mechanisms, position or alpha. Position is
now excluded by measurement.
Refutes my own unit 1 framing. I wrote that a quad can be "fully opaque and
entirely off-screen" and offered the travel as the likely explanation. It
is not -- the sweep is on screen at +41 frames, nowhere near the plate. The
travel explanation is dead, and I record it because I proposed it and it
steered the port's reading of their own renderer.

Took the port's point and dropped the alpha line. Three exchanges had gone
on alpha -- a bound, a refutation, a downgrade -- over 14 usable samples of
1754, when the position travels 2160 px monotonically in the same capture.
pteff03's declared leaf track is linear at 4.000 px/unit: -639 at t=0, -39
at t=150, 1521 at t=540. The capture's first clean segment runs frames
746..1913 with x from -641.1 to +1522.1. Both endpoints land within ~2 px
on a 2160 px travel, 0.1%. Two independent checks rather than one fitted
parameter. A single wrap at frame 1914 confirms the declared 600-unit loop
and falls after the segment.
Answers the clock origin: the leaf's t=0 is its first drawn frame, so the
game does not carry the leaf forward from the title's clock. That CONFIRMS
the port's own correction -- they had attributed ~135 units of earliness to
the leaf starting at title t=0 and withdrew it on two relayed numbers; the
full series says the withdrawal was right.
Rate here is 540 units in 1167 presents = 0.463 units/present, flagged as
the weak half: one run, in presents, and it does NOT match the 1
unit/present the splash work established. Either the leaf runs a slower
clock or one of the two is not what I think. The origin does not depend on
it.
And the useful negative: a linear fit across all 1754 samples gives max
residual 1108 px on 1402 px of travel, 79%, because the trajectory wraps
and a straight line through a sawtooth is meaningless. A fit not checked
for residual would have reported a slope and a plausible origin from that
same data -- which is exactly why the port's tool selftest must reject a
wrong-shape series, and why I segmented before fitting.

The port challenged the by-size identification: both sweep sprites are the
same size, so size cannot separate pteff03 from pteff03a, and the two
leaves floor at 128 and 0. They were right, and it is broken a third way.
Their discriminator -- the leaves travel in opposite directions -- is in
the capture I already had. Both rows drift +2.19 and +2.18 in x, i.e. BOTH
LEFT TO RIGHT, so both are pteff03. The 0.7% size difference is per-frame
rounding splitting one element across two keys, not two elements. pteff03a
does not appear in this capture at all.
And my own presentation misled. The "alphas 8 24 33 50 58" I quoted were
sorted(set(...))[:9] -- the nine LOWEST DISTINCT values, not the series.
Read as a trajectory they look like a ramp from 8. They are a tail. The
counts: 9 of 1140 and 5 of 614 samples below 128, so 14 sub-floor samples
out of 1754.
The bound argument survives in shape and collapses in weight. A sample
below 128 is still unexplainable by a leaf flooring at 128, but 14 of 1754
is a thin tail and a tail is where a vertex-grouping slip or a partial
frame would show up. Downgraded to amber: not refuted, not established.
Settling it needs the same capture read as a SERIES rather than a set --
alpha against frame across t=70..100, where a multiplying parent must
produce a monotone ramp on nearly every frame rather than 14 stragglers.
One more read of data already on disk.
The port was right to hold the renderer. Adopting this would have changed a
rendering rule on every screen with a leaf, on 14 samples I had presented
as a trajectory.

Question, look-at and not-covered written before the work, per PROTOCOL's
units section.
One boot, one A to skip the attract video, then no input so the title
builds in undisturbed. The sweeps are the two rotated 600%-scaled strips,
identified by size: NDC 1.38x3.15 and 1.39x3.15, matching the corpus's own
independently measured AABB height of 1134 px (2*1134/720 = 3.15).
Drawn alphas run 8, 24, 33, 50, 58, 74, 83, 100, 107 and 16, 41, 67, 91,
116, 128... pteff03's LEAF alpha is bounded below by 128 (keys 0:255
150:128 540:255 600:255). 8 < 128, so the leaf cannot produce it alone.
The parent's alpha is multiplied in.
That refutes the port's screen_view.gd decode that "the leaf runs on its
OWN timeline and the parent's alpha is NOT multiplied in" -- which is
exactly what that file asked for. It flagged honestly that every
observation behind it had parent alpha 0, so "the leaf wins" and "the
parent is ignored because it draws nothing" were never separated, and named
t=100..238 as the separating interval. This capture is in that interval.
Bears on F6's original report: the parent ramps 0->255 across t=70..100, so
if it multiplies in the sweep is invisible before ~70 and dim until 100. A
human reporting it starts late is seeing a real gate -- the parent's ENTRY
ramp, not the 238 cluster, which unit 1 showed is an exit.
Reach: one boot; quads identified by size against a previously measured
AABB, not by name, since the draw stream carries no names. The bound
argument needs only that the leaf minimum is 128, which is from the disc.
It does NOT establish the combination is plain leaf x parent rather than
some other one that also dips below 128 -- only that the parent
participates.

One unit, per the new PROTOCOL section. Question, look-at, and
not-covered written before the work.
pteff03 and pteff03a -- the sweep parents behind ptloop01/ptloop02 --
declare 0:a=0 70:a=0 100:a=255 238:a=255 250:a=0. So they rise 70->100 and
fall 238->250. The brief's own warning was right: 238..250 is a fade-out,
the same shape ptcopyright uses, and ptcopyright starts nothing.
The sweep is declared visible from t=100, which is 136 units BEFORE the
plate reaches full alpha at 236, and is fading out by 238.
That contradicts the human's report that the sweep only starts when the
plate appears -- and the reason both can be true is the next unit.
ptloop01/ptloop02 are .rat leaves whose own timeline is a TRANSLATION:
ptloop01 runs x = -639 -> 1521 over a 600-unit loop, so at its own t=0 the
sweep sits off the left edge of a 1280-wide screen. The parent's alpha says
"drawn"; the leaf's position says "where". A quad can be fully opaque and
entirely off-screen.
Explicitly not actionable alone: this says 238 is not a start. It does not
say the port should show the sweep from t=100, because if the leaf is
off-screen there then both renderers can be correct on alpha and differ
entirely in what is visible.
Refutation of the brief's own lead that "236-238 is a synchronisation point
and a human reported a behaviour change there": the synchronisation is
real -- pteff02 at 236, ptlogo_back2eff and ptcopyright at 238 -- but the
reading is refuted. For the sweep it is where things END. A cluster of
keyframes marks a moment; it does not say which direction anything moves
through it.

A human says something is missing on the title. Something is: it plays BGM,
and two different cues.
Method with the control built in rather than bolted on. R4 wants a negative
to show the method finding the menu's cue first; this method cannot produce
a false negative for one screen because it does not look at one screen. It
finds every call of the play function in the image and reads the cue each
passes: 34 callers, cue ids 1103 x24, 1102 x3, 1107 x2, 1108, 1106, 1104,
category 4 on every one. 1103 is the cue the corpus already attributes to
the menu, and the method finds it 24 times.
GamePart_Title's neighbourhood is 0x821C4xxx-0x821C7xxx per the registry
page, and seven play sites fall inside it: 1103 at 0x821C52D0, 0x821C5620
(inside the phase handler sub_821C5580), 0x821C6188 and 0x821C6294; 1102 at
0x821C53B0, 0x821C5BA0 and 0x821C6DE0.
So the title plays BGM_103 and BGM_102, and 1103 is the SAME cue as the
menu's -- which is why a port playing nothing on the title sounds like
something is missing rather than merely quieter.
The sting is NOT answered and the page says exactly why: this play function
carries ids in the 1102-1108 BGM range, the UI stings are SE_* cues with
ids 1-322, and not one of the 34 sites passes an id in that range. SE goes
through a different call and this method is blind to it by construction.
That is a bounded negative about the instrument, not the game, and reading
it as "no sting" would be the third time this corpus mistook a blind spot
for a fact.
Reach: exhaustive over every bl to 0x8217ACF8, so complete for that
function. The GamePart attribution is by address neighbourhood and carries
the registry page's own "by position and convention, not proven" caveat.

Claude-Session: https://claude.ai/code/session_01Jc4pciRArGHfxGGhEbwp5t
Third and last site: the executable's play path. sub_821C5580's cue-1103
site is li r5,1103 / li r4,4 / lwz r3,0(r29) / bl 0x8217ACF8, i.e.
play(this, category, cue_id). No volume is passed and no float argument is
set up by the caller at all; the callee's prologue confirms r5 is the cue
id with -2 and -1 sentinels.
Honest limit stated: the callee saves f30/f31 so it uses floats internally
and could look a level up for itself. "No gain is passed" is not "no gain
exists" -- but there is nothing at this site for the port to transcribe.
So F2 closes as undecodable-with-reach with all three sites checked:
tables.pak cue records (exhaustive, passing control, and numbers carry
names there so a gain would have had one), sound.pak bank headers (all 9519
entries, no readable header), and the play path (category, not level).
The port authors the mix and now knows it is authoring, which is what this
question existed to make explicit rather than accidental. The one authored
value the game exposes is the user-facing sound options screen -- a runtime
master, not a per-cue table.
Refutation of the play-test's premise that "a cue record commonly carries a
volume beside its wave index": REFUTED for this game across all three sites
where it could live. Recorded because it was a good prior -- it is what
sent me to the right three places -- and being wrong about where a value
lives is different from being wrong to look.

Continued F2 at the site the previous page named as the first thing to do.
dat/sound.pak is a 114 KB index over ~1 GB of payload across sound.p00-p04.
Its 9519 entries carry no readable signature at all: the most common
first-four-bytes pattern is "...." on 3830 entries and no entry begins with
an ASCII magic. Exactly one entry is under 4 KB (#9454, 533 bytes), where a
bank header or wave index would be small and structured.
So the SE bank's metadata is not reachable as a header in sound.pak. The
entries are audio payload, high-entropy by nature, and a gain beside a wave
index is not sitting in front of them.
Stated as a negative about REACHABILITY, not existence: a per-wave gain
could live inside a container these entries are compressed into and I have
not decompressed one.
Two of three sites now checked, both negative; the executable around
sub_821C5580 remains. Classification unchanged at undecodable-with-reach,
but better bounded.
Records the shape the answer is taking: if the executable also has no
per-cue gain, the honest conclusion is that the game does not author a
per-cue mix at all and the levels come from the user-facing sound options
screen as runtime state. That makes the port's job authoring a master
balance rather than transcribing a table -- undecodable rather than
decoded, which it must know, because a mix authored in ignorance and one
authored deliberately look identical in the file and differ entirely in how
far they can be trusted.

The port has no gain anywhere and confirm sits 3 dB above the music. Asked
the disc rather than choosing a number.
Five audio-bearing objects in tables.pak, zero tokens matching VOL GAIN
LEVEL DB ATTEN AMP MIX LOUD. Control passes: the same matcher finds 38
SE_UI hits, so "0 hits" is not a broken matcher.
The negative is stronger than a name search usually is, and I expected it
not to be. Dumping the schema shows the token stream is value-then-key
pairs -- "40, LINE_PITCH", "0, Y_OFFSET_ANALOG_STICK" -- so NUMBERS ARE
TOKENS AND THEY CARRY NAMES. A gain in this format would have a name, and
the name search covers exactly the space where it would live. That turns "I
did not find one" into "one is not there in this file".
Reach, and it is why this is undecodable rather than decoded: I did not
check the .slb bank headers, which is the other conventional home for a
per-wave gain beside a wave index -- and is where the play-test's own
framing points. No .slb exists as a loose file on the extracted disc, so it
costs a pak extraction I did not have budget for; it is the first thing the
next attempt should do. Nor did I check the executable, where a mix could
be immediates in the sound-play path around sub_821C5580.
So this is not "the mix is not on the disc". It is "the mix is not in the
table where a cue's fields live".
Pointer, not a finding: object #15 lists po_sound_scr.prt -> SOUND among
GP_OPTIONS' screens, so a user-facing sound options screen exists and at
least one volume is runtime state.
Port keeps authoring nothing yet.

The port needs an initial delay and a repeat interval and has shipped the
mechanism with -1.0 rather than invent them. This builds the instrument and
does not get the numbers.
The vertex stream is the right instrument: C_PAD_DECODER has no timer on
any direction path, so the repeat is in the layer above and cannot be read
out of that function; a cursor move is a quad changing position, and the
guest's vertex buffer carries that with no Canary processing in the path.
tools/re-capture/menu_repeat_probe.sh arms the logger, drives the boot with
pad-file presses and holds a direction. It ran its whole sequence. But the
boot did not reach the menu: in the settled era every quad shape holds a
constant y, and the shapes are near-full-screen rects rather than a button
list. No cursor, so nothing to repeat.
Two instrument errors worth more than the failed run.
The first attempt ARMED NOTHING and said nothing -- xdotool search --class
... --window %1 F10 behind a || true. The run completed normally and only
the ABSENT log revealed it. The working form looks the window up by name,
activates it, and sends F10 to the window and globally; a missing window is
now fatal rather than tolerated, because a silent arming failure is
indistinguishable from a screen that draws nothing.
My first cursor detector measured the wrong change: presents where the SET
of quads changed, which fired on 157 of 161 adjacent pairs because during a
build-in everything animates. Tracking one quad shape's POSITION instead
correctly reports no motion. That is the play-test's own lesson landing on
me -- an instrument that measures change can still measure the change of
the wrong thing.
Next run must not drive the boot blind: gate the presses on a classifier or
join with boot_menu.sh, which reaches the menu but takes screenshots rather
than draw logs. Blind was chosen because screenshots cost ~10 s each while
xenia runs; wrong trade, since a mistimed press costs the whole run.
Reach: the negative is about this run, not the game. F1 stays open and the
port should keep its -1.0 constants.

Chasing F1 I examined a counter block I had skipped. this+0x10 decrements
every update and fires output bit 0x4 at zero, guarded against the HELD
word by cfg +0xA0; it is re-armed from +0xC4 = 10 and +0xC8 = 8.
So my statement that "the only two timed inputs in the whole decoder are LB
and LT" is false, and two constants I tabulated as ring-word button masks
(B|Y and Y) are counter reload values. A number that is a valid mask AND a
valid duration cannot be told apart by its value, only by its use, and I
classified those two by value.
What it does not change: F1 is still not answered. This channel is guarded
by cfg +0xA0 = ring bit 1 = B, not a direction. The D-pad and left-stick
paths still carry no counter, so "a held DIRECTION has no repeat timer in
C_PAD_DECODER" stands, and the human's observation that it repeats in the
real game is consistent with the caveat this page already carried: the
repeat is in the layer above.
Explicitly NOT offering 10 and 8 as F1's two numbers. They belong to a
channel on a button that is not a direction, and at 60 units/s they are
0.167 s and 0.133 s -- about 7 moves a second, which does not match "a
medium pace, slow enough to see which item is selected". Reporting them as
the menu repeat would be the same read-a-config-infer-a-behaviour error
this correction is about.

The port asked whether the PRESS (A) plate pulses and with what period,
framing it as "does the timeline loop at 244 or does something else drive
it". Both halves of that disjunction are wrong about ptbtn00.
ptbtn00 ramps, holds, extinguishes at t=244 and stays out. The pulse is
ptbtn00f -- the plate's focus/glow variant, reached through focus_link and
carrying no top-level element of its own -- which declares a 120-unit loop
from the disc. A reader looking only at ptbtn00 sees a one-shot because the
looping element is the one a declaration-order walk never reaches. Same
element that needed the by-name accessor in ui_layout, for the same reason.
Cross-check that makes it more than a stopwatch reading: 120 declared units
at the rate law is 2.000 s at 60 Hz, against a measured mean of 2.24 s over
four intervals -- 12% long, the direction and roughly the size Canary's
pacing produces.
Stated plainly as what it is not: the port asked for a per-frame series and
this is not one. The four intervals come from the screenshot probe, the
weaker instrument, carrying a wall-clock duration off an emulator with
load-dependent pacing -- the class that has cost this corpus four withdrawn
timing claims. The strong instrument has never reached this screen: five
attempts, blocked by wall-clock timeout, frame cap, a self-matching pkill,
and the title sitting past the 137.7 s attract movie.
So the fact and the period are answerable now; the trajectory within a
cycle is not, and I am not inferring its shape from declared keyframes when
the whole point of the splash exercise was that only a capture confirms
shape.

Answers H1's first half with a negative, and decodes what the timing
constants are for.
C_PAD_DECODER's +0xB4/+0xB8 and +0xBC/+0xC0 (10 and 90, twice) are not a
key-repeat delay/interval pair. They are two identical channels of a
DOUBLE-TAP detector, on cfg +0x74 (LT) and +0x70 (LB), firing output bits
0x20 and 0x40.
The mechanism, from the image: both timers tick down once per update; a
press arms the short timer to 10; a RELEASE adds 1000 to it as a flag
stored inside the counter, which is why the tick watches for exactly 1000
and clears both there; a second press while the flag is set arms the long
timer to 90; and while the long timer runs the output bit is asserted on
EVERY update, with the short timer re-armed to 1010 each time.
So it is a latch, not a repeat: a double-tap opens a 90-update window and
the bit is held for its whole duration. That is a dash or barrel-roll
shape, which fits the buttons it is wired to.
H1: the directions have NO timer. The D-pad and left stick reach the output
word through bare mask tests -- the four left-stick literals at 0x8220C458,
C474, C490, C4AC, and DPAD DOWN through cfg +0xA4 -- with no counter
loaded, decremented or tested on any of those paths. On the evidence of
this layer a held direction does not repeat.
Reach: one layer. A menu could implement repeat on top of a held bit, and
this says nothing about that -- but it does establish the repeat is not in
the shared decoder, so it would have to be per-screen. "One step per
deflection" stays authored for the port; this narrows rather than settles.
Refutation of my own earlier note that a decoder "is where a game normally
puts its repeat timing, its edge detection and its button remap": remap
survives, edge detection survives, repeat timing is REFUTED. That clause
was a prior about how games are written, not a reading of this one.
Also commits tools/ppc-dis, the minimal PowerPC disassembler this corpus
has been rebuilding in scratch and losing to container restarts three times
in one session.

Walked the route the bounded-negative page named -- trace down from the
quad emitter -- and got one step.
sub_822380B0 is not a geometry emitter. It fetches a vertex pointer from
sub_823C2AC0, stashes it at this+0x20, then loops over an array of item
POINTERS at this+4 bounded by this+0x0C and this+0x10, loading a type tag
from item+8 and dispatching on it. So the object is a draw QUEUE and this
function consumes it.
That is a partial answer to a different open question:
ui-quad-class-foothold.md records that no function iterating screen
elements has been found. This iterates UI items and dispatches per item.
It is a draw queue rather than a screen's declared element list, so it is
not that walk, but it is the consumer immediately downstream and the type
tag at item+8 is a concrete field to chase.
Still not the interpolator: alpha is already decided by the time an item
reaches the queue. The evaluator runs before the enqueue, so the next step
is whoever pushes items -- the writer of +0x0C/+0x10 on this object.
Recorded as an increment, not a finding: one function identified by
disassembly, no behaviour measured, identification resting on code shape
alone.

The port pre-registered a test and ran it: against live-splash-publisher.png
a cropped render scores RMSE 558.1 (0.85%) and a scaled one 10118.8
(15.4%). Cropping is 18x better.
Confirmed here independently, from a different observable: the committed
captures are 1279x675, 1280x690 and 1252x754. VARYING heights. A fixed
presenter resample produces one size; crops of differently-sized windows
produce exactly that spread. And ui-render-tone-curve.md had already
recorded every capture aligning at dy=0 dx=0 with correlation 0.9466, which
a 0.9375 vertical scale cannot produce -- the evidence was in the corpus
before I wrote the claim.
So the captures are crops of a 1:1 surface, and every RMSE, glyph count and
surface mean against them is pixels to pixels with no filter to caveat. The
blanket "everything measured off a PNG carries the resample" is withdrawn.
Not refuted: the cvar reading. Canary does letterbox by default. What is
refuted is my inference that the corpus's capture path went through it.
Whether the presenter is bypassed, the window is 1:1, or the tool crops
before saving is open and unestablished.
The error is the one this session keeps paying for: I read a configuration
and inferred a consequence FOR THE DATA without testing it against the
data. The test costs one render and one RMSE and I had every capture needed
to run it.
Also downgrades my refutation of the corpus's oracle principle from
"survives with a qualifier" to "survives, and my qualifier was wrong",
kept rather than deleted because the failure is the instructive part.
Section 1 (gamma: VdGetCurrentDisplayGamma is kStub, the splash shader has
no pow/ramp/lookup) and the two-path distinction stand unchanged.

Answers question 3 of the 2026-09-02 play-test, from Canary's own source.
Gamma: Canary applies NONE. VdGetCurrentDisplayGamma is declared kStub and
only reports kernel_display_gamma_type (default 2, TV/BT.709) to the guest
so D3D can build a ramp. And the guest does not apply one either, for the
splash: its dumped pixel shader is four ALU ops -- tfetch2D, three muls, a
max -- with no pow, no ramp, no lookup.
Geometry: yes, the presenter resamples. present_letterbox defaults true and
present_safe_area_x/y default to 100, so the guest's 1280x720 is scaled to
fit the window and letterboxed with nothing cropped. That accounts for a
number the corpus has carried without explaining: captures measure the game
surface at 1279x675, and a single-pixel oracle placed at 1280x720
coordinates read the copyright line instead.
The structural consequence is the useful part. There are two measurement
paths and only one has Canary in it:
pixels guest draw -> EDRAM -> resolve -> front buffer ->
presenter (scale + letterbox) -> X11 -> screenshot -> PNG
=> carries a resample
vertex stream guest CPU writes a vertex buffer -> the draw logger reads
guest memory directly
=> carries nothing
The per-frame alpha series is the second path, which is why it can be
stated as the game's values rather than as pixels we measured. Everything
measured off a PNG carries the resample: every RMSE against a capture,
every glyph count, every surface mean.
Refutation attempt on this corpus's own founding principle, "the oracle is
the real game running in Canary, captured": it SURVIVES but needs a
qualifier it has never carried. A PNG capture is the oracle plus a
resample. Harmless for ordering, counts, durations and change; a filter in
the path for anything pixel-exact. The vertex stream is the stronger oracle
and should be preferred where the question can be asked of it.
Not measured: the resample's actual filter. I read the cvars saying scaling
happens, not the kernel doing it.

Question 1's behavioural half is answered elsewhere and measured. This is
the other half -- which function -- and it is not found. Recorded as a
bounded negative so the next attempt does not repeat four searches.
Excluded, all by exhaustive scans of the image:
integer lerp shape (divw with mullw and subf within 10 instructions):
28 sites image-wide, NONE in the UI region 0x82200000-0x823FFFFF
mulli by 40, the keyframe record stride: 31 sites, NONE in the UI region
addi rX,rX,40 in the UI region: 43 sites; the screen/bundle ones at
0x823CCA6C and 0x823CCA94 disassemble to a 40-byte container COPY loop
(CTR=10, ten-word copy), a vector reallocation, not an evaluator
fmadd-family in the UI region: 811 sites over 142 pages -- too diffuse to
select on, so float is neither excluded nor narrowed
The first two together say the evaluator does not compute its fraction with
integer multiply-and-divide and does not index records by multiplication.
With the measured steps landing on exact integers, the likeliest remaining
shape is a float lerp with a per-segment reciprocal, converted to a byte --
stated as a hypothesis, not a finding.
Names the route I would take next and did not have budget for: trace DOWN
from the quad emitter. sub_823C2AC0 has exactly 6 callers, four of them
sibling emitters, and sub_822380B0 reads its colour from this+0x04..0x10.
Whoever writes those fields is one step from the interpolator.
Reach stated: the two opcode negatives are exhaustive over the whole image
rather than sampled, but they do not exclude the interpolator living
outside the UI region, which is an assumption inherited from
ui-quad-class-foothold.md and not independently checked.
Not blocking the port: it needs whether to lerp and how, which is answered.

Answers question 1 of the 2026-09-02 play-test: interpolate or hold. It
interpolates, piecewise-linearly, evaluated once per present at one unit
per present.
palogo_sqex_eff gives 28 distinct alphas over 28 consecutive presents,
changing on 26 of 27 adjacent pairs. It is not one slope, and the disc says
why: that element declares 0:a=0 -> 15:a=255 -> 30:a=212 -> 45:a=0, three
segments with three gradients. Predicted -2.87 and -14.13 per unit against
measured modal steps of -3 (x6) and -14 (x9). The declared keyframes
predict the per-frame steps, which makes this a prediction rather than a
description.
So the port must lerp: hold-to-next-key would emit 3 states where the game
emits 28. And "eased" is the wrong description -- there is no easing
function, the envelope only looks eased because consecutive declared
segments have different gradients.
Alpha lives in the per-vertex k_8_8_8_8 colour, rewritten into a fresh
vertex buffer every frame. Not a PS constant (ps_c[n=0] on 1048/1048), not
a blend factor, not a texture swap.
🔴 And the game's splash is ALSO mostly frozen. Measured with the same
statistic the play-test used on the port: the game moves 21.2% and 27.8%
against the port's 16.4%, and its longest frozen run is 3.34 s against the
port's 3.20 s. The publisher declares 205 of 255 units -- 80% -- as a flat
hold at full opacity.
That refutes the play-test's second clause. "A fade does not hold one
picture for 3.20 s" -- this one does, for 3.34 s. Its first clause stands:
26 states for a 45-unit build-in is too few, the game gives 49 and 51.
The deficit is the state count, not the freeze: ~100 against 26. Acting on
the second clause would have sent the port to remove the one part of its
splash that is already right.
Not answered: which function does it. This is the behaviour; the
image-side half of question 1 is still open.

The port observed that the justification for 60 has changed three times
while the number never moved, and that three routes sharing an upstream
assumption are weaker than they look. Checked. They do share one.
Route B needs "the guest presents 60x/s", which comes from the vblank
histogram UNDER XENIA'S 60 HZ LIMITER. Route C needs "the vblank is 60 Hz",
which is that limiter's cvar directly. Route D is a wall-clock duration
that lands on 60 only because the vblank is 60 Hz and Canary roughly keeps
up. All three reduce to one fact: the display refreshes 60 times per second
on this emulator. I presented them as corroboration and that was wrong.
What is actually established, by manipulation rather than agreement:
units/second EQUALS the display refresh rate. Forcing 30 Hz gave 30.2
units/s; at 60 Hz it is 59.8/61.3. One factor changed, the output tracked
it.
It becomes "60 units/s" only via an external fact this corpus has not
measured -- that an Xbox 360 outputs 60 Hz. That is a hardware
specification and it is solid, but it belongs outside the measurement
rather than laundered into a third agreeing route.
The conditional form is more useful anyway: it says what to do on hardware
that is not 60 Hz, which is exactly why the port's time-based clock at a
fixed 60 units/s is the right construction rather than a coincidence. And
it keeps the port's `authored` classification correct -- nothing here
promotes it.
Also sizes the clock-origin capture properly. FRAMES=9000 ran to completion
still in the movie at 8999, so the cap really fired this time. Content
hashes show 3967 distinct decoded frames against ADV.wmv's declared 4131 --
96% complete -- at 1.79 presents per decoded frame, not the 2.00 I assumed,
which is why the estimate was short. Needs ~294 more presents to clear the
movie plus >=236 for the plate, so FRAMES=11000.
Free on the way past: 3967 decoded frames over 7091 presents at ~52
presents/host-s is 29.1 movie frames/s against the disc's declared 30.000,
a 3% match that ties the present rate to a disc fact rather than a clock.

h3 says 2 units per guest frame, units-per-second-measured says
time-integrated at 56.8 units/s, and my own page says 1 unit per present.
All three rest on real data and one mechanism explains all of them: the
clock advances one unit per VBLANK, and presents can be dropped without the
clock caring.
That accounts for the corpus's steps of +17/+34/+51 (1, 2, 3 vblanks
between two logged presents), for the same animation spanning 21 labels in
one capture and 33 in another -- which a strict per-present clock cannot
produce -- for h3's three plate steps of 23, and for my own 14 consecutive
steps of 17 in a run that dropped almost nothing.
My "1 unit per present" was nearly right and named the wrong clock. At
--framerate_limit=30 Xenia vblanks at 30 Hz and the guest presents ~30/s,
so presents and vblanks coincide and the test could not tell them apart. It
correctly refuted time-integration; it could not locate the tick.
Solid: the RATE follows the vblank rate. 255 declared units take 4.26/4.16 s
at a 60 Hz vblank and 8.45 s at 30 Hz -- 59.8/61.3 against 30.2 units/s. A
time-integrated clock predicts 4.25 s in both. So a console at 60 Hz gives
60 units/s, and the port's value stands on a third independent route.
Not solid: per-vblank vs per-present. My step samples are ~12 per run,
which cannot separate them, and I say so rather than reading 18% vs 0% of
two events as support. The load-bearing observation for the mechanism is
the corpus's 21-vs-33, not mine.
The discriminating experiment is named and not run: log Xenia's
D1MODE_V_COUNTER beside each present and check every step is exactly
17 x (vblanks elapsed).
