Issue #49: the repos carry code, tooling and docs only.
Untracks 143 screenshots, 3 savegame blobs and `tools/re-capture/ob_digits.png`
(a digit-template sheet cut from game frames) -- 146 files, 76.4 MB. They stay
in the working tree and are gitignored, so the pages' relative links still
resolve where the captures exist and nothing ships.
Derived measurements (csv/tsv/txt/log/json/jsonl/npy) are our own numbers, not
game content, and stay tracked -- they are what most claims rest on.
`check-capture-citations` had its contract inverted, and it is the half worth
reading:
* presence now comes from the WORKING TREE, not `git ls-files`. The assets are
deliberately untracked, so asking the index would report every screenshot as
missing and fail all 203 citations.
* a NEW failure: a game asset that IS tracked. A screenshot that sneaks back
in is invisible in review -- a binary shows as "Bin 0 -> 1234567 bytes" --
and is permanent once merged, since removing it later needs a history
rewrite. So that half has to be loud.
Verified:
* selftest 8/8, including the new rule
* scan: 212 present, 212 cited, 0 dangling, 0 tracked -> exit 0
* force-add one PNG -> "game assets TRACKED: 1", exit 1, selftest red
⚠️ This does NOT remove the blobs from history; a clone still fetches them.
That needs a filter-repo rewrite and a force-push, which is a separate,
human-run step.

`GAME_CONTENTS.md` sat in the workspace root through the whole consolidation,
adopted by neither repo -- the corpus documents formats in depth but never said
what files the disc holds or where they sit.
Re-measured rather than transcribed, and that caught a real error: the source
placed `resource3d/`, `DefTables` and `MiscBin` under `dat/`. All three are in
`hidden/` -- which is why `SYLPHEED_RES3D` points at `hidden/resource3d`.
Counts, the language table and `media_id` (0x2D2E2EEB, from the XEX header)
re-verified against the retail extract.
Half the source was pre-RE speculation phrased as status -- `dat/*.pak` marked
"Unknown, magic bytes TBD" when the container is decoded disc-wide, plus a table
guessing each archive's contents from its name. Carrying that forward would put
claims into the corpus the corpus has already refuted, so it is dropped and the
page says what was dropped and why. INDEX.md stays the single authority on
format status.

Nothing here changes what a tool computes; it changes where tools look.
- tools/re-capture: 33 censuses globbed /work/sylph_extract, a path that has
existed nowhere since /work became a clone, so they matched nothing and
printed empty results. They now resolve the disc through a new disc.py
from $SYLPHEED_DISC and exit loudly without it (the #44 fix, generalised).
Nine scripts that imported siblings from the retired Reborn checkout or an
old session scratchpad now import from their own directory. unitgroup.py
only needs the variable when --pak is not given.
- sylpheed-xex: the loader only ever uses the XEX2 retail key. The dead
devkit key and a doc comment claiming a devkit fallback that does not
exist are gone; Project Sylpheed is a retail XEX2, so no XEX1 key either.
- sylpheed-viewer: real_font_rasterizes looked for /tmp/sylph_extract and so
always skipped. It reads $SYLPHEED_DISC now, and passes against the disc.
- Comments and docs that named xenia-rs, the Reborn repository or /work/*.pe
as places to look now name sylpheed.db, Canary's ppc_context.h and the
flat .pe; docs/re/README.md no longer says the native Canary build does not
run.
Historical records keep their original paths: findings that were measured
against /work/xenia-rs/sylpheed.db still say so.

Instructions and generated text that still sent readers to `xenia-rs`, which is
archived and deleted locally. Provenance and dated research records are left as
they are — "lifted from xenia-rs", or a finding stating what database it was
measured against, is still true, and rewriting it would falsify the record.
Changed, because each one tells someone what to do today or writes stale text:
docs/re/README.md the RE toolchain guide queried `xenia-rs/sylpheed.db`
with `xenia-rs/zq.py`, and its "Dynamic" bullet said
to prefer xenia-rs's probe suite OVER Canary. Now:
`sylpheed.db` at the repo root (how to build it and
re-stamp names), `tools/zq.py`, dynamic = Canary, and
`.rdata` reads from the `.pe` (offset = VA - 0x82000000)
in place of `--dump-addr`.
challenge-mission-gate.md, structures/achievements.md
reproduction commands `python3 xenia-rs/zq.py dis …`
crates/sylpheed-xexdb/SCHEMA.md
titled after the retired `xenia-analysis` crate,
citing `xenia-rs dis`, pointing at a `xenia-analysis`
source path
sylpheed-xexdb/src/formatter.rs
WROTE "generated by xenia-rs" into every disassembly
it produced (no test pins the banner)
sylph-xexdb.rs, db.rs "SQLite" / "DuckDB writer for xenia-rs"
sylpheed-formats/src/hash.rs
pointed at `xenia-rs/RE_SYMBOLS.md`, now at
`docs/re/RE_SYMBOLS.md`
Verified: every rewritten reproduction command was extracted from the doc and
run as written against the regenerated database — all 5 exit 0 and return the
disassembly they describe. The README's function count (25 676) is the database's
own. `cargo fmt --all -- --check` clean.
Not changed, deliberately: the README's Oracle bullet says Canary's native Linux
ELF "crashes / does not run". That is about Canary, not xenia-rs, and it conflicts
with a July note that the native build works — unverified either way here.

Phase 3 lifted the DuckDB tool out of `xenia-rs` but not the two files that go
with it, and this branch's own code already depends on one of them: the FK rule
in `db.rs` and `db_schema_golden.rs` exists *because* `apply_re_symbols.sql`
re-stamps reverse-engineered names onto `functions` after every regeneration.
Sylpheed referenced that file three times and contained it nowhere — on no
branch. CONSOLIDATION.md's end state is "Sylpheed holds everything", and the
`xenia-rs` clone is scheduled for deletion.
docs/re/RE_SYMBOLS.md byte-identical to xenia-rs/RE_SYMBOLS.md (cmp)
tools/apply_re_symbols.sql every statement identical; the two comment lines
that name paths now name this repo's paths
Verified against the real 336 MB database, which carries all 16 foreign keys,
inside a transaction that was rolled back (the database is unchanged):
every statement runs, and 208 functions carry reverse-engineered names. Run
from both the old location and this one.
Not harvested: `xenia-rs/zq_dis.py`, an untracked six-line subset of
`zq.py dis` with a hardcoded path — superseded, nothing to keep.

CONSOLIDATION.md Phase 4. `tools/port/check-citations` has checked
`docs/port/*.md` since it was written; `docs/re/` never had one, and
`docs/re/captures/` is the largest thing in the repository -- the one place a
file can be added, never cited, and never noticed.
captures committed : 212
cited by a page or a tool : 212
cited but NOT committed : 0
🔴 THE PREMISE I STARTED FROM WAS WRONG FOUR TIMES, AND EACH CORRECTION IS IN
THE TOOL RATHER THAN JUST IN MY HEAD:
* "10 dangling citations" -- the real number was ONE. Eight were DIRECTORY
references, which resolve and are simply absent from `git ls-tree`; one was
a path at the end of a sentence with the full stop pulled into the match.
A checker that cries wolf nine times in ten teaches you to ignore it.
* The one real dangler, `live-submenu-unidentified.png`, was COMMITTED and
then deleted on 2026-08-30 while the page kept citing it and kept making
the claim it backs. Restored from cab62796 rather than dropping the link:
deleting evidence while keeping the conclusion is the thing this corpus
exists to prevent.
* Two "orphans" are opened BY FILENAME from `screen_match.py`, which builds
the directory separately. A path-only scan called them unreferenced and
deleting them would have broken the tool. The check now counts any
basename named anywhere.
* Pruning then EMPTIED two directories that pages cite as directories, and
the check went red on the very citations that made them evidence. It
caught its own damage. A file inside a cited directory is cited.
The selftest covers all of it, including the failure that actually happened:
an earlier version passed five green ticks while the scan silently returned
NOTHING, because `git grep -E` is POSIX ERE and cannot compile `(?:`. A
selftest that cannot see the failure that occurred is decoration.
46 orphaned captures dropped, 30.7 MB from the checkout. ⚠️ That reclaims no
repository space -- the blobs stay in history -- and it is not meant to. It
means every capture here is now evidence some page or tool actually uses.

No emulator-requiring state/approved item was open this iteration (issues
#1, #3, #5 all landed and moved to state/needs-human; #25 still awaits
approval). Used the gap for corpus consistency instead of idling, per the
same "a correction that never reaches the row someone reads" failure this
project keeps naming.
1. menu-navigation-semantics.md's own Q4 table still said NEW GAME was
"not tested" and its own prose said it was "deliberately not pressed"
and hangs the emulator -- both refuted BY THIS SAME PAGE on 2026-08-28,
34 lines further down ("NEW GAME -- measured ... it is not a hang. It
opens DIFFICULTY then SELECT DATA"). The correction never propagated
backward into the table or the status line above it, so a reader
stopping at either would come away with the wrong (and already-refuted)
answer. Fixed in place, struck rather than deleted, with the actual
destination and an honest note that DIFFICULTY has no id-table name
match (already refuted separately) while SELECT DATA plausibly matches
GP_SELECT_STORAGE as a fresh, low-confidence guess.
2. Found the identical failure mode in my own recent work: HANDOFF.md's
original Q1-Q10 summary table (near the top of a 6600+ line file) still
quoted the 2026-08-30 "no auto-repeat" finding as current, three commits
after this same session measured 12 frames delay / 4 frames interval
through a repeat-capable driver and explained why the earlier negative
was a driver limitation, not a game fact. A reader who only sees the
summary table -- which is exactly what a long file trains a reader to
rely on -- would get the withdrawn answer. Fixed with an explicit note
pointing at the current entries rather than silently editing the number
in place, so the correction itself stays visible.
Refutation-shaped either way: two claims ("NEW GAME untested", "no
auto-repeat") checked against this corpus's own newer evidence and found
not to survive, recorded rather than left to be rediscovered.
Continues the static lead from two iterations ago
(f3-title-sting-mechanism-found-not-value.md) with the dynamic half it
named as the next step. Booted with --xma_param_probe=true (the same
census menu-audio-cues.md used for the menu's SE cues), no pad input,
recording continuously from window-open: a glyph time series (not a
threshold trigger) and every newly-seen XMA-PARAM stream, stamped on
arrival since Xenia's own log carries no timestamps.
Positive control, and a real one: the probe caught the title's two BGM
stems starting at t=147.6s, matching f3-title-plays-bgm-102-and-103.md's
already-established finding exactly -- the instrument finds a real stream
before being asked to find nothing.
From the plate's first visible activity through 68 seconds of build-in
plus fully-settled pulsing (killed at t=220.1s), zero new XMA streams
appeared beyond the two BGM stems and three unidentified early ones (boot
splash, not this question). No SE-range stream, no second BGM, nothing --
measured, not the prior static reach limit.
Refutation attempt this iteration, recorded either way: my first read of
the fine-grained glyph series said BGM and the plate's build-in start at
"essentially the same moment". Checking the raw per-sample data instead of
a coarse table refutes that -- first non-zero glyph reading is ~0.67s after
BGM onset, and immediately noisy rather than a clean climb. Corrected in
the doc rather than left as an overclaim for someone chasing frame-accurate
sync later.
Reference data: docs/re/data/f3-sting-{glyph-timeseries,xma-param-arrivals}.tsv
-- derived numeric/log-line data, not a capture of rendered game content.
Direct follow-through on this session's own named next step. The prior
result (f1-held-down-measured-no-repeat-via-file-driver.md) concluded the
file driver cannot show menu repeat because its GetKeystroke() never emits
a REPEAT-flagged event, and that the menu's repeat is very likely driven by
that flag rather than raw polled state. Testable, so tested: patched
/canary/src/xenia/hid/file/file_input_driver.h to add opt-in repeat behind
a new --pad_file_repeat cvar (off by default, every other scripted script
unaffected), using the SDL driver's own constants verbatim
(HID_SDL_REPEAT_DELAY/_RATE = 400/100, guest-time ms via
Clock::QueryGuestUptimeMillis) rather than re-deriving them. Incremental
rebuild, ~1 minute (only xenia_main.cc needed recompiling).
Control: the driver's own log confirms repeated keystroke events fire as
designed, zero crashes.
Result: re-ran the identical held-DOWN capture. The cursor that moved once
and stopped in the null result now cycles continuously through the whole
5-item menu, wrapping, for as long as the button is held -- the null result
was real for that driver path, and giving the driver the one thing it
lacked reverses it completely.
Measured at this run's achieved 29.87 fps guest rate: 12 frames (~402ms)
initial delay from the press-triggered step to the first repeat step; 4
frames (~133ms) steady-state interval for 13 of 15 gaps, 3 frames (~100ms)
for the other 2 -- slower than the raw 100ms constant driving it, which
this page flags but does not trace further (most likely the game batches
drained keystrokes per its own frame tick rather than reacting to each one
instantly). The 4-frame figure is what matters for the port: it's what the
cursor visibly does.
Honestly scoped: this measures what the game does when FED repeat events
shaped like the SDL driver's, not a capture through an actual physical
controller (none exists in this container) -- classified measured, not
decoded, for exactly that reason. One run only; the corpus's two-run
minimum isn't met, flagged rather than overclaimed.
f1_hold_capture.py gains an optional `repeat` argument. The Canary source
patch itself lives in /canary, outside this repo (Canary source, not
sylpheed-formats) -- fully described inline in the finding doc so it can be
reapplied if that tree doesn't persist across a container reset.
Reference data: docs/re/data/f1-repeat-cursor-transitions.tsv -- every
transition's frame, guest tick and Y position, not the raw draw log.
Fifth boot attempt this session, first clean one, using the harness debugged
last iteration (env-safe input, wide capture window, signed-in profile,
blanked X root). Reached the menu, held DOWN 2.5s wall-clock, armed the F10
draw capture, released, killed -- zero crashes.
Achieved vs requested: 433 of 600 requested frames, spanning 14.43s of GUEST
time against ~4.5s wall-clock for the hold+tail window -- this run went at
~3.2x real time (a cheap static menu, nothing pacing it to a display
refresh). The 2.5s wall-clock hold covers roughly 8s of that guest time.
Method: track one quad shape's position per frame via read_draws.py, not a
screen diff -- the approach f1-menu-repeat-harness-built-not-answered.md
already named as correct. Exactly one shape-group moves at all: one jump of
~0.21-0.225 NDC units (matching the known one-menu-item pitch), complete
within 4 frames / 133ms guest time of arming, then flat (a ~0.0125 pulse
wobble only) for the remaining 427 frames / 14.3s of guest time. Broadening
the match threshold finds no other moving element.
This is a STRONGER negative than the 2026-08-30 result it agrees with (that
one sampled a screen diff at ~4-5fps for 2.0s; this reads every quad every
frame for ~8s of guest-time held) -- it survives, rather than confirms, last
iteration's "coarse sampling hid a fast repeat" alternative, which does not
survive a per-frame instrument over a much longer window. Refutation
attempt against my own prior lean, recorded: it does not survive.
Reconciled, not left in conflict: the human's play-test and pad.py's
"auto-repeats" warning almost certainly went through a REAL controller
(Canary's SDL driver), which auto-repeats keystrokes at a documented
upstream 400ms/100ms (guest time) via the REPEAT keystroke flag. The file
driver deliberately never emits that flag, by design -- so it cannot show
repeat regardless of how carefully or how long it's held, which is exactly
the negative measured here. Still no F1 number; now a specific, well-
evidenced reason the file driver alone will never produce one, and a named
next step (add opt-in REPEAT-flag support to the file driver, matching the
SDL driver's constants, then re-run this exact capture) -- not attempted
this iteration, a second unit on an already-complete one.
Reference data: docs/re/data/f1-cursor-quad-y-per-frame.tsv -- the derived
per-frame Y position and guest tick, not the raw draw log itself (a capture
artifact, kept uncommitted per the corpus's game-content rule).
Tried to close out issue #1 with an actual draw-log measurement this
iteration: built f1_hold_capture.py to boot to the settled main menu via the
proven glyph-gated route, arm the F10 UI-draw capture, hold a direction, and
read cursor position per frame -- the instrument f1-menu-repeat-harness-
built-not-answered.md already validated but never got to run against a
reachable menu.
Four bugs found across four boot attempts:
1. tap() shelled out to pad.py without this script's own env, so the press
went to /tmp/xenia_pad.txt while Canary watched OUT/pad.txt -- an
unobserved press indistinguishable from a dead pad. Fixed with an
in-process tap() using the same pad() the hold uses; confirmed working
the next run (title 154.5s, menu 163.0s).
2. ui_draw_capture_frames/max were persisted at 3/20000 from a prior
session in xenia-canary.config.toml -- log_ui_draws is now a documented
no-op (F10 arms unconditionally) and these two cvars didn't visibly
respond to command-line overrides. Bumped to 600/400000 directly in the
config.
3. The real blocker: this container has no signed-in profile (no content/
directory at all -- a fresh container after a restart, which every
container is right after one). Without a profile the title's sign-in
dialog sets IsUIActive() true, which reproduces
structures/title-a-press-fault.md's already-diagnosed unbounded-
keystroke-queue crash -- verified byte-for-byte against that page's own
addresses (PC 0x868 past sub_82457038, 0x828F3xxx registers, identical
host/guest address arithmetic), looping continuously from before F10 was
ever pressed. Fixed by creating a profile (--create_profile_if_none) and
signing in (--logged_profile_slot_0_xuid), matching boot_menu.sh, which
already did this and so never hit it. Confirmed: zero crashes with the
fix, dozens per run without it.
4. Found but not re-verified: no xsetroot blank before launch, so a stale
X-root frame from a killed prior run gave a false "TITLE" read at 2.6s,
before any real window existed -- skip_intro.sh already blanks the root
for exactly this reason. Fixed in the script.
Ran out of budget before a clean end-to-end run landed. Still no number for
issue #1 -- the Port keeps -1.0. Flagged prominently (HANDOFF, REFUTED.md)
because bug 3 will hit any bare run-canary invocation in any fresh
container, not just this script.
Continuing the F1 investigation rather than starting a fresh one. Last
iteration left two competing hypotheses open (Keystroke-queue-driven vs
polled-state-driven repeat) and flagged C_PAD_RINGBUF's producer as the
cheapest thing to trace next -- named but not traced.
Traced it this time: C_PAD_DECODER's own constructor (sub_8220B610)
allocates C_PAD_RINGBUF (52-byte control struct, 1024-byte backing buffer,
confirmed against its own Shift-JIS trace strings -- "C_PAD_RINGBUF
initialization" and its allocation-error message). Its update function
(sub_8220B8C0) takes the input-manager singleton as a parameter and reads
the ring at offsets 12, 36, 40, 44 and 48 -- not just the one button word.
Offsets 36-48 are four consecutive fields read together through the same
int-to-double conversion an analog axis would use. XamInputGetKeystrokeEx
has no field for a stick position, so a structure carrying four axis-shaped
fields cannot be a keystroke queue -- it reads as a periodically-refreshed
polled-state snapshot. My own prior reading of the "ring buffer" name as
implying a queue was the wrong inference; refuted by tracing it, recorded
either way per adversarial duty.
This shifts the balance toward the second, previously-uncertain hypothesis:
the file driver's GetState() was always capable of showing real repeat (no
modification needed), and nav_repeat_and_b.py's null result is more likely
a sampling artifact of its ~4-5 fps screen-diff detector than a structural
driver limit. Revises "what would close it" accordingly -- re-run the
existing draw-log position-tracking instrument, gated on the menu properly,
before reaching for a driver change.
Not found: the actual producer that writes into C_PAD_RINGBUF each frame --
narrowed to "reachable from the input-manager singleton fetch in
sub_821A9DC8," not traced to completion. Still no number for issue #1;
this narrows the path to one, further than last iteration but not there.
Issue #1's premise (the human's play-test: a held direction repeats) directly
contradicted menu-navigation-semantics.md's 2026-08-30 "no auto-repeat"
row. Read the instrument before trusting either: nav_repeat_and_b.py drove
input through Canary's --hid=file driver, and that driver's GetKeystroke()
is explicitly, deliberately built to deliver exactly one event per held
press ("scripted input wants precisely one event per press, and repeat is
what makes menu steps overshoot" -- file_input_driver.h's own comment).
input-pad-read-path.md already established the game reads menu input via
this same Keystroke API. A driver engineered to prevent repeat cannot be
evidence the game lacks it -- the counter's control (a tap gives 1 spike)
proved the counter works, not that the driver could show more than one.
Not a clean reversal, and said so: the same driver's GetState() holds a
button continuously with no edge suppression, and pad.py's own docstring --
written by an earlier session driving this exact tool -- warns that a longer
dpad hold "auto-repeats and overshoots," describing an observed effect
through this same driver. The two pieces of evidence disagree and this page
does not resolve which wins.
Also read from Canary's source: the SDL input driver (what a real controller
goes through) auto-repeats keystrokes at 400 ms initial delay then 100 ms
interval, guest time (HID_SDL_REPEAT_DELAY/RATE, upstream Xenia, not a
project change) -- a concrete, testable prediction for what the real number
could be if the menu treats repeat-flagged keystrokes as nav steps, matching
the human's "medium pace" description. Not yet measured.
Refutation attempt this iteration, recorded per adversarial duty: targeted
the 2026-08-30 "no auto-repeat, ✅ measured" claim. Survives only partially --
demoted to unsettled, not flipped to a confident opposite. New REFUTED.md
section (Menu navigation and input) and the row in
menu-navigation-semantics.md both corrected in place, old text kept per
convention.
What would close it: trace C_PAD_RINGBUF's producer (keystroke ring vs
polled state) statically, or add an opt-in repeat mode to the file driver
and read cursor position off the draw log per frame. Neither run this
iteration -- this is the static half, and reversing a standing claim is
enough for one unit without stacking a build-and-boot run on top of it
unverified.
f3-title-plays-bgm-102-and-103.md's BGM census resolved a literal
`addi r5,r0,<imm>` before every call to the play primitive, which is blind by
construction to a cue id supplied any other way. Two of the primitive's 34
callers ARE supplied another way -- one is a register passthrough inside a
generic 6-caller wrapper `sub_821CCCB0(obj, cueId)` with a -1 "don't play"
sentinel. One of its six callers chains back to slot 1 of GamePart_Title's
OWN dispatch table at 0x820a3dec, identified by its adjacent
RegisterToFactory<0, class silph::GamePart_Title> string -- the same
convention already used disc-wide for the other 28 GameParts, not a
neighbourhood guess this time.
Traced as far as static analysis goes: the field that would carry the cue id
traces to a 19-caller shared helper's return value, too common to be
title-specific -- reads as "allocate a sound-emitter handle", not "here is
the cue". The value most likely gets set at whatever runtime moment the game
wants this emitter to speak, which a disassembly listing does not contain.
Classified undecodable-with-reach, not a fourth thing -- narrower and
better-aimed than the prior reach ("SE goes through a different call").
Every address cited was independently re-decoded from the raw .pe bytes
(file offset = VA - 0x82000000), not taken from the database's own
mnemonic/operands columns, and all agree.
Refutation attempt this iteration: checked whether the "6 callers is
exhaustive" claim for sub_821CCCB0 survives indirect dispatch (a plain
kind='call' xref scan is blind to a vtable/function-pointer-array entry).
Checked function_pointer_array_entries and kind='ind_call' xrefs for all
four functions in the chain -- none found. The claim survives.
What would close it: --xma_param_probe=true during a title boot's build-in,
watching for a newly-decoded stream when the plate reaches full alpha with
no input -- the same technique menu-audio-cues.md used for the menu's SE
census. Not run this iteration; this is the static half only.
f6-out-of-sample-RESULT.md left three failures unexplained beyond "n=2 wasn't
enough". Reviewing what's already decoded: two of the three (the ptcopyright/
parent ramp ratio, the sweep-leads-plate lead) fail in the SAME direction
(0.75x, 0.71x of predicted), and f6-unit10 already established the sweep and
plate families are gated by separately-triggered parents -- a ratio across
two independently-triggered elements has no structural guarantee of being a
constant, unlike a ratio internal to one element family (which is exactly
what the passing three checks are). The gross mislabeling that caused the
ORIGINAL 1.7x conflict was fixed two days before the prereg was written, so
that's ruled out as the cause here; whether the cross-group phase genuinely
varies boot to boot vs. an artifact in the frame-based ratio math is still
open, and needs more captures to tell apart -- filed as a follow-on, not run
here.
check_labels.py conflated two different claims under one "N LABEL(S) DRIFTED"
verdict: identity checks (which element -- clock-free, still 3-for-3 out of
sample) and timing checks (a cross-element ratio and a self-consistency curve
fit -- 0-for-2 out of sample). Split into two reported groups; only identity
gates the exit code now. Tolerances untouched -- widening them to pass f6c
would be tuning the check on the case that failed it, the same error class
already named twice in this corpus. Verified with synthetic data shaped like
the real f6c residue (3/3 identity, 0/2 timing, exit 0) and confirmed the
selftest's injected mislabel still fails an identity check (exit 1) -- no
capture exists in this fresh container to run it against real logs.
The withdrawn sweep->plate lead (0.138-0.141) stays withdrawn. Nothing here
reinstates a number.
One fresh no-input boot against predictions registered before it. Sweep-
internal quantities pass on a run that had no hand in deriving them: leaf
period ratio 1.1753, size ratio 1.3009, pulse/sweep 0.0963. Those are now
3-for-3 across captures.
The three plate-relative quantities fail, together and in the same
direction: ptcopyright ramp ratio 0.550 vs 0.733 (0.75x) and sweep->plate
separation 0.0996 vs 0.138-0.141 (0.71x). So the separation is not a
constant -- three runs give 0.138, 0.141, 0.0996 -- and my published "2.2%
agreement" was n=2. Withdrawn. The F6 conclusion survives qualitatively;
the number does not.
Also records that check_labels.py fails its first independent test. I
validated it on the two captures that produced the labels, which is an
instrument validated on its own training data. Two of four checks fire on
f6c. I am not guessing which of labels/tolerances/run-variation is
responsible.
Caught mid-analysis that I had first run the checks against a log still
being written; re-ran on the complete log and the numbers are identical, so
the failures are not a truncation artefact.

Every F5/F6 figure comes from captures taken for other purposes and
re-analysed after the reader and three labels were corrected. None has been
tested out of sample. Six predictions registered before the capture, five of
them checkable by check_labels.py, which now takes --cap NAME=path.
Prediction 6 is the one already got wrong once (0.057 against ptcopyright
instead of 0.14 against the real plate), and is stated so a landing near
0.057 would show the correction itself was wrong.

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

1.947x between two captures of the same animation, with the baseline moving

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.
