e57eda14e4 recover: the OPTIONS menu work from the deleted auto/port-p6-audio
The nine files touched by the OPTIONS commits of 2026-09-03 (77f1d18,
fda417a, 3efe1cc, 80042cb, 4c24e06, a921c1e, 41f1331, 6b4b1df, edf8979),
taken as of 0148cb8, the tip of auto/port-p6-audio. The branch was deleted
from the server on 2026-09-17 during the consolidation cleanup; issue #6
asks for this work as a reviewable PR, so it is recovered here before the
commits are garbage collected.

This is a review slice, not a self-consistent tree: the OPTIONS work and
the F5/F6 work interleaved in the original history and cannot be separated
by file, so each file carries whatever else had changed in it by
2026-09-04, and files it depends on are absent. The complete state is
recover/port-f5-f6.

Refs #6.

b305aa4a5a docker: support a long-lived Claude token, and stop the seeding fighting it
The rotating OAuth credential file is why the agents kept parking, and a
long-lived token removes the failure by construction instead of recovering from
it after the fact.

MEASURED 2026-09-04. ~/.claude/.credentials.json holds a refresh token that
ROTATES ON USE. Seeding both containers from the host left three clients holding
one token; the first to refresh invalidated the other two, and on the failed
refresh Claude Code CLEARS the stored tokens -- writes empty strings, keeps the
metadata, and parks at "Login expired".

  decoder credentials emptied  13:04:28
  decoder last transcript      13:04:29   <- one second later

The emptying and the park are the same event, which is why it never self-heals:
not a stale token a retry could fix, but no token at all, with no browser in the
container to complete /login. A hollow file passes every "does it exist" check --
508 B healthy against 280 B emptied -- which is how three separate diagnoses
missed it. And recovery re-armed the bug: after re-seeding, host and decoder held
the IDENTICAL refresh token hash.

`claude setup-token` issues a long-lived token against the same Claude
subscription. Checked, not assumed: `claude auth login` defaults to --claudeai
and it is `--console` that means Console/API billing, so this is not the separate
API bill. `CLAUDE_CODE_OAUTH_TOKEN` is recognised by the installed binary.

Passed as an ENVIRONMENT VARIABLE, both halves of the failure are gone: nothing
rotates, so peers cannot invalidate each other, and there is no file for Claude
Code to empty on a failure.

Both launchers read $HOME/.sylph-claude-token if present -- same pattern as
SYLPH_GIT_CREDENTIALS -- and both entrypoints skip OAuth seeding entirely when
the variable is set, because copying the rotating file in would re-create the
exact collision the token exists to remove.

Inert until the file exists. Without it, nothing changes.

Also worth recording for the preflight work: `claude auth status` prints JSON
with loggedIn/authMethod/subscriptionType. That is a far better SessionStart
assertion than checking a file exists, and it would have caught this on the first
iteration rather than the third incident.

108308057a docker: the expect wrapper swallowed both the signal and the exit status
A tooling review predicted a PID-1 signal problem from two symptoms we could not
explain: `OOMKilled: true` with **ExitCode 0**, and `--continue` failing to find
a conversation that plainly existed. Traced it, and the prediction was right --
though the culprit is not PID 1, it is one level below.

The path is  tini (PID 1) -> entrypoint.sh (exec'd) -> expect -> spawn -> claude

`spawn` CANNOT be an exec: expect has to stay alive to drive the pty. So expect
is the process Docker signals, and everything depends on it passing things on.
It did neither, in two lines:

1. NO SIGNAL FORWARDING, no trap of any kind. `docker stop` sent SIGTERM to
   expect, which died and took the pty with it. Claude Code never got a SIGTERM,
   so it never ran SessionEnd hooks and never wrote lastSessionId/history --
   which are written ONLY at a graceful shutdown. That is the entire reason
   `claude --continue` answered "No conversation found to continue" with 33 MB of
   transcripts in the volume beside it, and why we resume by scraping a session
   id off a transcript filename.

2. `eof { exit }` RETURNED 0 FOR EVERY DEATH. A bare `exit` in expect is exit
   ZERO. When the OOM-killer took the child, expect saw EOF and reported a clean
   exit. `OOMKilled: true` with `ExitCode 0` was never Docker being odd -- it was
   this line. It also meant `--restart on-failure` would read a memory kill as
   success, which is why the policy had to be `unless-stopped`.

Fixed and MEASURED, old against new, in a container:

  child exits 7        old -> 0    (the bug)      new -> 7
  SIGTERM to wrapper   old -> 143, child's trap NEVER RAN
                       new -> 42,  child trapped and cleaned up

Same file in both images; they were byte-identical, so the port copy takes the
same change.

Consequences worth stating: a kill now reports 137 rather than 0, so exit codes
mean what they say; `docker stop` gives Claude Code a real SIGTERM, so it runs
SessionEnd and writes the session index -- which may make the transcript-filename
resume unnecessary. That is not assumed here: the resume path stays as it is
until it is verified redundant.

620ec5e60b agents: one item only -- the title's animation timing -- and split work into human-checkable units
Two new findings from the human, both about WHEN a title animation starts, and
both handed over rather than guessed:

F5 Does (A) SNAP the title to finished, or ACCELERATE it? The human says they
   cannot tell and is right that they cannot -- a three-frame acceleration and a
   one-frame cut look identical to an eye. Two routes that should agree: a
   per-frame capture (acceleration shows intermediate alphas, a cut shows none)
   and the code (assigning a target time and raising a rate multiplier are
   different instructions). Their "looks more like a snap on multiple attempts"
   is recorded as a PRIOR, not a result.

F6 The title's sweeping white glow -- ptloop01/ptloop02, the blue PCB-like lines
   -- starts only when the plate appears in the real game, and starts earlier in
   the port. A lead from the exported declaration, mine and unverified: those
   elements are keyed at t = 0, 70, 100, 238, 250 while the plate reaches full
   alpha at 236, with pteff02 keyed at exactly 236 and ptlogo_back2eff and
   ptcopyright at 238. 236-238 is a synchronisation point in the declared data
   and a human just reported a behaviour change there. Flagged AGAINST itself
   too: 238...250 looks equally like an exit ramp -- ptcopyright uses that shape
   and starts nothing -- and the sweep lives in a nested .rat leaf with its own
   timeline.

F6 bears on clock: "shared" and on F4: if a title element does not move until
the plate arrives, either the declared data says so and our keyframe reading is
wrong, or something at the plate's arrival STARTS it, which is a mechanism
nobody has proposed.

And the process change, which is the human's and outlives this item:

  "attacking the 'whole' mission was too big for them to handle. Split the given
   missions and tasks into even smaller tasks which they can tackle and give to
   a human for feedback."

PROTOCOL.md gains "Work in units a human can check in a minute". A milestone is
not a unit of work, it is a bag of them. A unit is right-sized when it ends in
something a person can judge in under a minute WITHOUT READING ANYTHING, and
each one states its question, what the human looks at, and what it does NOT
cover. Do one, hand it over, stop -- an unverified fix under a second change
makes a regression two-variable.

The evidence for the rule is this week: the splash sat through a whole milestone
and took one day once scoped to "does it animate?". The bar is a HUMAN check,
not a green tool -- three instruments passed a frozen screen.

de5f04038d agents: correct "both clocks" -- there is ONE, and F4 tests whether it is right
I wrote "whether the game snaps both clocks forward" into yesterday's F4 and the
human asked which clocks. There are none: authored/flow.json sets
`clock: "shared"`, so the title's two composited builds -- build 4 the artwork
(finishes t~=118) and build 2/3 the plate (full alpha t=236) -- run on ONE clock
started together. Left standing, that phrasing sends an agent hunting for a
second clock this corpus says does not exist.

Corrected in both briefs and in the playtest page, marked as a correction rather
than silently edited.

And the question is better than I first framed it. `clock: "shared"` is
AUTHORED, and the port's own plate-arrival-halves.md calls it "not falsified...
not confirmed to better than ~20 % either", with an unresolved anchor
disagreement inside one binary: the reconciliation picked t=118 while
settle_time() returns 160 and the boot prints "settles at t=160".

So F4 is a TEST OF THAT PREMISE, and the discriminator is observable -- press (A)
early, while the wordmark is still building in, and watch the ARTWORK rather
than the plate:

  advances the shared clock   -> the artwork SNAPS to finished
  only forces the plate       -> the artwork KEEPS ANIMATING its build-in

Both briefs now say to answer F4 before building on `shared`, and tell the port
not to choose what "jump" means.

06f890361b agents: P5's gate is MET, and four findings from the same walk
"Menu walk and navigation is fine. Video skips too. Extras open. New Game
   shows new game intro video."  -- 2026-09-02

P5 is done. Its gate was "a human clicks through it", the retro said it had been
waiting on that and not on code for the whole milestone, and it has happened.
PORT-MISSION.md updated. The NEW GAME gap is accepted as-is.

Four findings, three of them the Decoder's:

F1 THE MENU REPEATS ON A HELD DIRECTION AND OURS DOES NOT. One step per
   deflection was authored as the conservative choice because nobody knew; a
   human has now watched the real game and it repeats, "at a medium pace... slow
   enough to see which item is selected". That settles the existence half of H1
   against us. The RATE is still unmeasured and must not be guessed -- the
   description bounds it and supplies no number. Decoder measures initial delay
   and repeat interval as frame counts; the port implements the mechanism and
   waits for the numbers.

F2 THE SFX ARE TOO LOUD BECAUSE THERE IS NO MIX AT ALL. Measured: confirm
   -17.7 dB mean / -0.0 dB peak, 3 dB hotter in mean than the music and 6.4 dB
   above move. No volume or gain value exists anywhere in export/ or authored/,
   so every clip plays at unity on one bus. Decoder: is per-cue or per-bus gain
   on the disc -- the cue table is the obvious place and cue 1103 is already
   decoded. Port: gains at PLAYBACK as data, and explicitly NOT normalisation in
   the exporter, which destroys the relationship between clips and cannot be
   undone by a modder.

F3 SOMETHING IS MISSING ON THE TITLE SCREEN. The export carries one music file
   and the port plays nothing on the title. Which cue does the title play, and
   is there a sting on the plate or on accept? A negative needs a positive
   control: find the menu's cue by the same method first.

F4 (A) SKIPS FORWARD THROUGH THE BOOT AND WE IMPLEMENT TWO OF THREE PRESSES.
   In the game: skip video, reveal plate immediately, accept plate. The middle
   one is missing here. Whether the game snaps both clocks forward or only
   reveals the plate is a question, not a detail -- and it is a cheap second
   route to the plate-arrival question, since a press that skips to the plate
   says where the game thinks the plate belongs.

H3, the plate delay, is ACCEPTED -- "feels the same... sufficient". Left
unattributed rather than closed green.

a71dea9b8d agents: the logo splashes are DONE -- the human cannot tell them from the game
"Looks good! Cannot notice any obvious difference from the actual game.
   Mark logos as done."  -- 2026-09-02

Not "the check passes": a person compared the port against the real game and
could not tell them apart. That is the oracle, and it is the strongest result
this port has produced. The sole-focus order is lifted; both agents return to
their milestones.

The fix was one word -- pose_at ASSIGNED the settle instant instead of clamping
to it, so every query returned the settled pose whatever the clock said. The
same line manufactured the false green: the capture harness shoots after two
frames, so it was photographing t~=2 units, which looked settled only because
everything looked settled. The 0.01 % agreement that closed H2 was measured
through the accident. One bug produced the defect AND the evidence of its
absence.

Verified here before it went to the human, by film rather than by claim:
motion 16.4 % -> 27.7 %, distinct luma states 26 -> 43, the publisher ramp 6
steps -> 13 in one continuous run, and the developer splash's interrupting
0.50 s freeze gone. The publisher trajectory rises to a peak and settles back --
the crossfade signature.

The port then closed a gap motion-census names in its own header ("a wrong ramp
that moves every frame passes here") with a shape check pre-registered from the
disc, measured off a film, on a non-overlapped strip, in ratios so the texture
divides out: rise:last declared 1.20, measured 1.20 exact.

Kept as the standing lesson, because it is the fourth instance: an instrument
that sits below the thing under test cannot see it fail. Ask of any new check
what it would still report if the feature were entirely absent.

Explicitly NOT claimed: P5's gate is "a human clicks through it" and nobody has
said the milestone is met. The briefs say so, and say not to record it on the
human's behalf.

The decoder's end-to-end pipeline work returns to normal priority rather than
being dropped -- it is what decides whether the port's 60 units/s matches the
game. The ramp is now right in SHAPE and unverified in DURATION.

d394c55cbb agents: the splash does not animate, and three instruments could not see it
A human on a GPU at ~140 fps: "the logos just switch, there is no animation at
all." Measured from a real boot with --film at 0.05 s, then per-frame change:

  splash moves        1.30 s of 7.95 s = 16.4 %
  publisher splash    0.30 s of motion, then 3.20 s FROZEN
  developer splash    0.35 s + 0.25 s, then 2.40 s FROZEN
  distinct luma states in 7.95 s   26

A 45-unit build-in cannot be drawn in 26 states, and a fade does not hold one
picture for 3.20 s. The frame counter says 24.8 fps achieved; both are true --
the port is DRAWING 25 times a second and CHANGING almost never.

🔴 Why every check passed, which matters more than the bug:

  frozen sweep     drives the clock BY HAND -- proves the renderer can draw
                   pose N, never that the poses are drawn in sequence
  settled compare  0.01 % against the capture -- a screen frozen 84 % of the
                   time matches a settled reference PERFECTLY, that is what
                   frozen means
  achieved fps     counts frames DRAWN -- the same pixels 25x/s scores
                   identically to animating

Every one measured throughput or a pose. None measured CHANGE. Same shape as
InputEventAction bypassing the input map: the instrument sat below the thing
that was broken, so the break could not appear in it.

tools/motion-census closes the class. It measures change and nothing else, and
its --selftest asserts it separates a fade (97.4 % moving) from a switch (2.6 %)
from a frozen film (0.0 %) -- a detector that cannot tell those apart would
report the same green line on all three.

Both briefs: this is the SOLE focus. The port reproduces before changing
anything and gates every fix on a film rather than a still. The decoder maps the
whole pipeline end to end -- disc bytes, the game's per-frame update (does it
interpolate between keyframes or hold?), what is submitted per frame, and what
Canary does to it before a capture records it -- delivered as a SERIES, not a
settled value.

The port should also record the refutation against itself: H2 reads ANSWERED on
the strength of the frozen sweep. The mechanism half stands, the blur is a baked
companion texture. The behaviour half does not.

18b5b3d5f1 port: give the port container a GPU path -- it never had one
Reported as "the port has low FPS". Godot 4 renders through Vulkan and this
launcher passed nothing through, so it fell back to lavapipe: software Vulkan,
correct and slow. The decoder's launcher has had this block for a long time;
the container that actually runs a renderer was the one without it.

Same three cases as the decoder, including the part worth repeating: passing
/dev/dri alone does NOT work for NVIDIA -- Mesa cannot drive the card and the
proprietary userspace lives outside the image. It needs the container toolkit.

The NOTE now prints the full repo-add sequence, because the package is not in
Ubuntu's default repos and `apt install nvidia-container-toolkit` on its own
fails with 'no installation candidate' -- which reads like the package is
wrong rather than the source being missing.

4ac23b94dd docker: auto-restart, and resume the session the agent was actually in
The decoder died mid-task and it took four separate findings to explain, each
of which read as something else:

1. OOM-KILLED, REPORTED AS A CLEAN EXIT. `OOMKilled: true` with **ExitCode 0**.
   So `--restart on-failure` would treat a memory kill as a successful finish
   and leave the agent down -- the policy has to be `unless-stopped`.

2. THE JOB CAP WAS SET AND THEN REMOVED THREE LINES LATER. build-reborn has
   always exported CARGO_BUILD_JOBS, but a raw `cargo test --release -p
   sylpheed-formats` never reaches the wrapper. Adding `-e CARGO_BUILD_JOBS` to
   the launcher did not help either: the entrypoint recomputes and exports over
   it unconditionally. An explicit value now wins, and says so in the log.

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

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

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

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

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

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

The oracle measured 2.138 s and 2.132 s. The gap is presentation rate: the emulator presents at 28.1 fps against a nominal 30, and the corpus had independently measured the idle title at 28.5 fps before these runs. \ud83d\udd34 CORRECTED 2026-09-01: this said `ptbtn00` reaches 255 at t=238 and that the difference is 120 units = 2.000 s. It reaches 255 at t=236 and HOLDS to 238, so 238 is the last opaque frame, not the arrival; 236 - 118 = 118. The port printed the contradiction in one sentence on every boot. The correction moves the reconciliation by 0.033 s and overturns nothing -- see docs/port/plate-arrival-halves.md. \ud83d\udd34 AND THE ANCHOR IS NOW OPEN.

Whether the title shows the plate when it is REACHED AGAIN -- by (B) from the main menu, or after the attract movie -- is not measured, and putting the overlay on the screen would quietly claim it is. \ud83d\udccc SOURCE, added 2026-09-01: the plate belongs to the boot's overlay step rather than to the title screen because its arrival is measured against the boot clock -- docs/re/title-plate-delay-measured.md. \ud83d\udd34 STALE CLAUSE, CORRECTED 2026-09-01: this said \"Whether the title shows the plate when it is REACHED AGAIN -- by (B) from the main menu, or after the attract movie -- is not measured\". It IS measured now, and has been since 2026-08-30: after (B) from the menu the plate is re-drawn, pressed at 351.2 s with its pulse back at 358.5 s (the Decoder, nav-autorepeat-and-settled-b data). The port re-arms the overlay on arrival at the title by any path, and that is correct. What stayed true is the structural half -- the declaration lives on the boot STEP and is looked up from there, so a screen that gains an overlay gets it on both paths at once. \u26a0\ufe0f What is STILL not measured is whether the returned plate FADES or appears at once; the 7.3 s between press and pulse is consistent with a transition plus the declared 214->236 fade, but that is consistency, not a measurement of the ramp on this path.",
"no_pulse_why": "The port draws the plate arriving and then holding. It does not pulse it. The RE agent identifies the pulse as the plate's FOCUS RECORD `ptbtn00f` -- a glow ramping 0x00 to 0x50 and back, t=6..105 -- not as a loop of `ptbtn00`'s own group, which was the port's earlier reading and was wrong. Looping that record is a candidate the port has NOT taken: its group is 105 timed units plus an AUTHORED 24-unit exit ramp, and hitting the measured 2.24 s mean requires composing that authored constant with a loop assumption, which is tuning rather than measuring. Filed in BLOCKED.md. \ud83d\udccc SOURCE, added 2026-09-01: docs/re/structures/plate-pulse-measured.md, and the phase-lock caveat that bounds what a gated capture can show is docs/re/structures/plate-pulse-phase-lock.md."

"why": "HANDOFF Q2/Q6: the boot reaches the title after the intro movie. This is the LAST step, and a last step is where the sequence stops rather than fading out -- a boot that ends by fading to black looks like a boot that crashed. P5 gave the title somewhere to go, but that is a HANDOVER and not another boot step: `--boot` still stops here, and `--boot --play` hands the same held title to the menu flow, where (A) opens TITLE_MENU. Kept as a stop rather than folded into `screens` because what the boot does is authored from a measured sequence, and what (A) does is a separate measurement."

Delete this the day the RE agent finds what selects it. CORROBORATED 2026-08-29, and still not decoded: the committed capture live-main-menu.png has NEW GAME focused. Identified by rendering all five focus states and taking the minimum difference -- 531 differing pixels against 6080-7094 for the others, an 11.5x margin -- with the method controlled on live-main-menu-options-focused.png, whose answer is in its filename and which it picks by 4.7x. That means the port's choice matches the state of one committed frame. It does NOT make focus stable: Q5's four boots gave TUTORIAL, TUTORIAL, NEW GAME, NEW GAME, and this identifies one frame rather than a rule. Delete this entry the day something says what SELECTS it. TIGHTENED 2026-08-29: Q5 now has SIX boots, and the shape is sharper than 'unstable' -- TUTORIAL x3, NEW GAME x3, and NO OTHER ITEM EVER OBSERVED. So it is not uniform over five buttons; whatever selects it has to explain a two-way split. That does not change this choice (NEW GAME remains one of exactly two observed states, and it is the state of the committed capture) but it does change what would REFUTE it: a boot opening on LOAD GAME, OPTIONS or EXTRAS would break the two-way shape, and a rule that predicts the split would delete this entry outright.",

# ZERO. So when the kernel OOM-killer took the child, expect saw EOF and
# reported a clean exit -- `OOMKilled: true` with `ExitCode 0`, which is not

# Docker restarts a container that EXITS. A Claude session sitting at

#
# never exits. The process is healthy, the container is Up, `docker ps` is green,
# and the agent has done nothing for hours. Three times now (2026-08-30,
# 09-02, 09-03) that has been noticed only because a human saw Remote Control
# report "Can't reach your computer" — which is a symptom of the session being
# unable to attach, not a report about the machine.
#
# The fix is already in the entrypoint: it copies the host's credentials in when
# they are newer than the container's. It just needs something to notice and
# bounce the container. That is all this does.
#
# ⚠️ It restarts rather than logging in. A restart re-runs the entrypoint, which
# re-seeds credentials AND resumes the session by id, so the agent keeps its
# context. There is nothing here that could log a session in on its own, and it
# should not pretend to: if the HOST's credentials are also stale, this loop will
# bounce the container and the agent will park again. It says so instead of

*"Deliberate AFAIK, in actual game the difficulty select comes first."* The port
announces the two screens it skips; that stays as it is.
---
## F1 — 🔴 The menu DOES repeat on a held direction. Ours does not.
> *"Moving stick up/down and holding only moves one item. In game it actually
> continues to move when holding up/down, just at a medium pace so player does
> not need to move pad middle↔up/down, but also slow enough to see which item is
> selected and move to target."*
**This settles the existence half of H1, and it settles it against us.** One step
per deflection was authored as the conservative choice precisely because nobody
knew. Now somebody has watched the real game: **it repeats.**
⚠️ **The RATE is still not measured, and it must not be guessed.** The human's
description bounds it usefully and does not supply a number: fast enough that a
player need not return the stick to centre, slow enough to read the selection as
it passes. That is a range, not a value.
* **Decoder — measure it.** Hold a direction in Canary and count. Two numbers:
the **initial delay** before the first repeat, and the **repeat interval**
after it. Frames between cursor moves, at a stated present rate — a count, not
a stopwatch reading ([`TEMPORAL-VERIFICATION.md`](TEMPORAL-VERIFICATION.md)).
Also: does the d-pad differ from the stick? Does the rate accelerate while
held, or stay flat?
* **Port — implement the mechanism, take the number from the Decoder.** Do not
ship a placeholder rate: an invented interval here is indistinguishable from a
measured one a month from now, and this is the exact field where that has
already cost us once.
## F2 — 🔴 The sound effects are too loud. There is no mix at all.
> *"Largely OK. Biggest notice is the volume, many effects are too loud."*
**Measured, and the human is right.** Every clip plays at unity gain, because
**no volume or gain value exists anywhere** — not in `export/`, not in
`authored/`, not in the manifest:
| | mean | max |
|---|---|---|
| **`se/confirm`** | **17.7 dB** | **0.0 dB** — at full scale |
| `se/move` | 24.1 | 1.4 |
| `se/back` | 21.0 | 5.7 |
| `bgm/main_menu` | 20.7 | 4.2 |
`confirm` is the loudest thing in the export: **3 dB hotter in mean than the
music** and 6.4 dB above `move`. A game mixes SE against BGM on separate buses;
this port has one bus and no gains.
* **Decoder — is the mix ON THE DISC?** The obvious place is the cue table: a
cue record commonly carries volume alongside the wave index, and
`sub_821C5580` is already known to play cue 1103. If per-cue or per-bus gain is
there, it is **decoded** and nobody has to choose. If it is provably not, say
so with reach and it becomes an authored mix.
* **Port — do not normalise in the exporter to fix this.** Re-levelling the file
destroys the relationship between clips and cannot be undone by a modder.
Gains belong at playback, as data, where a measured value can replace a chosen
one without re-exporting.
## F3 — ❔ Something is missing on the title screen
> *"I also think that there is a sound track or effect missing at the title
> screen."*
The export carries exactly one music track, `bgm/main_menu.ogg`, and the port
plays nothing on the title. Whether the game does is unestablished.
* **Decoder:** which cue, if any, does the **title** play? The menu's is decoded
(cue 1103 = `BGM_103` via `sub_821C5580`); the same route should answer the
title. And is there a one-shot **sting** when the plate appears, or when Ⓐ is
accepted? Either would read as "something missing" to a player.
* ⚠️ A negative here needs a positive control (R4): show the method finding the
menu's cue before concluding the title has none.
## F4 — 🔴 Ⓐ SKIPS FORWARD through the boot. We only implement one of the three.
> *"In the game one can get the plate to immediately show by pressing Ⓐ,
> essentially skip to it. So after the logos one can immediately skip to the main
> menu by pressing Ⓐ three times: 1. skip intro video, 2. show plate, 3. the
> plate itself."*
A measured behaviour of the real game, and a good one — it is how a returning
player gets past the boot.
| press | in the game | in the port |
|---|---|---|
| Ⓐ #1 | skips the intro video | ✅ implemented |
| **#2** | **completes the title build-in and shows the plate immediately** | ❌ **missing** |
| Ⓐ #3 | activates the plate → main menu | ✅ implemented |
* **Port:** Ⓐ during the title build-in should jump the sequence to the plate's
arrival rather than being swallowed. ⚠️ **Careful what "jump" means, and do
not choose it.** See below — it is a test of an authored premise, not a detail.
* **Decoder:** what does Ⓐ do to the clock? This is also a **second, cheap route
to the plate-arrival question** — a press that skips to the plate tells you
where the game thinks the plate belongs.
### 🔴 F4 is a TEST OF `clock: "shared"`, which is authored and only ~20 % confirmed
**Correction, by the human who wrote this page: an earlier draft said "both
clocks". There is only ONE.** `authored/flow.json` sets `"clock": "shared"`: the
title is two composited builds — build 4 the artwork, build 2/3 the plate — and
they run on **one clock started together**. Build 4's artwork finishes at
`t ≈ 118`; the plate reaches full alpha at `t = 236`. Saying "both clocks" would
send someone hunting for a second one that this corpus says does not exist.
With that fixed, the question is sharp and **observable**:
| if Ⓐ … | then pressing EARLY looks like |
|---|---|
| **advances the shared clock** | the title artwork **snaps** to finished, and the plate appears |
| **only forces the plate visible** | the artwork **keeps animating** its remaining build-in while the plate appears over it |
So film a boot, press Ⓐ while the wordmark is still building in, and watch the
**artwork**, not the plate.
📌 **Why this matters beyond the feature.** `clock: "shared"` is **authored**, and
`plate-arrival-halves.md` says in its own words that it is *"not falsified… not
confirmed to better than ~20 % either"*. There is also an unresolved anchor
disagreement **inside one binary**: the reconciliation picked `t=118`, while
`settle_time()` returns **160** and the boot prints `settles at t=160`.
If Ⓐ snaps the artwork, that is evidence **for** one shared clock. If the artwork
carries on while the plate appears, the plate has a timeline of its own and the
authored premise is in trouble. **Answer F4 before building on `shared`.**
* 📌 And it bears on `REFUTED.md`: *"any title after the first one refuses
input"* is already narrowed to the attract-returned title. This is a third
input the boot title accepts.
---
## F5 — Ⓐ: does the animation SNAP, or accelerate? **A human cannot tell.**
Follow-up from the same human, and the honesty in it is the useful part:
> *"I think the animation speeds up to the finished state. So it is not a snap in
> the sense of a cut, but rather becoming much quicker — which however feels
> instant too, so it is difficult to discern by a human. It might also actually
> snap/cut to the finished state, but appear as a quick animation… Similar to how
> videos work by quickly playing distinct frames. So I cannot tell certainly
> which it is. Upon multiple attempts it does look more like a snap. Decoder
> still should verify."*
**This is a question the oracle-by-eye cannot answer, and it is being handed over
as such rather than guessed.** A three-frame acceleration and a one-frame cut are
indistinguishable to a person; they are trivially distinguishable to an
instrument. Two independent routes, and they should agree:
1. **Per-frame capture.** Press Ⓐ mid-build-in and read the submitted alphas
frame by frame. An acceleration shows **intermediate values**; a cut shows
one transition and none. This is a counting question — see
[`TEMPORAL-VERIFICATION.md`](TEMPORAL-VERIFICATION.md), and note that the eye
failing here is exactly why.
2. **The code.** Whatever Ⓐ does to the clock is a store somewhere: does it
assign the target time, or raise a rate multiplier? A snap and a speed-up are
different instructions, and the image says which.
⚠️ The human's *"looks more like a snap on multiple attempts"* is a **prior, not
a result.** Do not let it stand in for the measurement, and say so if the
measurement disagrees with it.
## F6 — 🔴 The title's sweeping glow starts TOO EARLY in the port
> *"…blue geometric lines (like on a PCB, straight lines and rectangular or 45°
> turns). These have a white glow moving on them as an animation. In the game
> this animation only starts when the plate is shown — basically the animation
> starts the same as the 'insert' of the plate. In the port it already starts
> before the plate arrives."*
**The elements are `ptloop01` and `ptloop02`** — already known to this corpus as
the sweeps whose leaf *"sweeps a 400 px quad whose left edge travels
639…1521"*, and whose free-running on the settled title is a ❌ entry in
`REFUTED.md` (they **do** free-run). Nothing there says **when they start**, and
that is the whole of this finding.
### 📌 A lead, from the exported declaration — MINE, unverified, check it first
`title.json` gives `ptloop01` and `ptloop02` keyframes at:
```
t = 0, 70, 100, 238, 250
```
and the plate reaches full alpha at **`t = 236`**. They are not alone: `pteff02`
has a key at exactly **236**, and `ptlogo_back2eff` and `ptcopyright` at **238**.
**236238 is a synchronisation point in the declared data**, and the human has
just reported a behaviour change at that instant.
So the first question is cheap: **is the sweep's motion declared to begin at 238,
with the port instead free-running the leaf from t=0?** If so this is a decode
question with a decoded answer, and nothing needs authoring.
⚠️ **Two reasons not to take that lead as the answer.** The `238…250` pair looks
just as much like an **exit ramp**`ptcopyright` and `ptlogo_back2eff` use
exactly that shape and they are certainly not starting anything. And the sweep
lives in a **nested `.rat` leaf** with its own three keyframes, so the parent's
envelope and the leaf's motion are different timelines. Which of the two the
human is watching is the thing to establish.
### Why this one is worth prioritising
It bears directly on **F4 and on `clock: "shared"`**. If a title element does not
begin moving until the plate arrives, then either the declared data says so — in
which case the shared clock survives and our reading of the keyframes is wrong —
or something at the plate's arrival **starts** it, which is a mechanism nobody
has proposed. Either answer constrains the clock question that F4 is also
probing.
## H3 — the plate delay is ACCEPTED
> *"Delay feels the same. Cannot verify it is exact same, but is sufficient."*
Good enough to stop working on, **not** established as correct. Leave the row as
unattributed rather than closing it green; if the duration question is ever
settled by the pipeline work, check it against this rather than re-opening it
from scratch.

# Play-test, 2026-09-02 — the splash did not animate. **Now fixed and signed off.**
## ✅ CLOSED THE SAME DAY — the human's verdict, which is the only gate that counts
> *"Looks good! Cannot notice any obvious difference from the actual game.
> Mark logos as done."* — 2026-09-02
**The logo splashes are DONE.** Not "the check passes" — a person compared the
port against the real game and could not tell them apart. That is the oracle,
and it is the strongest result this port has produced.
⚠️ **Both agents: the sole-focus block is lifted.** Return to your milestones.
What remains open from the play-tests is listed at the bottom of this page; none
of it is this.
### The root cause was one word
```diff
- t = settle_instant if settle_instant >= 0.0 else min(t, settle_units(element))
+ t = min(t, settle_instant) # the comment above it already said "stop at"
```
`pose_at` **assigned** the settle instant instead of clamping to it, so every
query returned the settled pose whatever the clock said.
🔴 **And the same line manufactured the false green.** The capture harness shoots
after two frames, so it was photographing t ≈ 2 units — which *looked* settled
only because everything looked settled. **The 0.01 % agreement that closed H2 was
measured through the accident.** One bug produced the defect and the evidence
that the defect was absent.
### Verified independently before it went to the human
Filmed a real boot at 0.05 s, before against after:
| | before | after |
|---|---|---|
| splash in motion | 1.30 s / 7.95 s (16.4 %) | **2.20 s / 7.95 s (27.7 %)** |
| distinct luma states | 26 | **43** |
| publisher ramp | 0.30 s, 6 steps | **0.65 s, 13 steps, one continuous run** |
| developer splash | two bursts split by a **0.50 s freeze** | **one continuous 0.90 s run** |
The publisher trajectory rises to a peak and settles back — the **crossfade
signature**: glow alone, then both, then sharp only. The developer splash's
interrupting freeze disappearing is the clearest single sign the clock now drives
the poses.
The port then closed a gap `motion-census` names in its own header — *"a wrong
ramp that moves every frame passes here"* — with a shape check pre-registered
from the disc, measured off a film, on a strip no other element overlaps, in
**ratios** so the texture divides out: middle:last declared 0.203 / measured
0.213, rise:last declared 1.20 / measured **1.20 exact**. It agrees with the
Decoder's independent measurement of the running game.
### 🔴 The lesson, which outlives the bug
Three instruments passed a frozen screen. Keep this: **an instrument that sits
below the thing under test cannot see it fail.** A frozen sweep drives the clock
by hand; a settled comparison is *defined* to pass on a frozen screen; an
achieved-fps counter counts frames drawn, not frames different. Ask of any new
check: *what would this still report if the feature were entirely absent?*
---
## The original report, kept for the record
The human, watching the port on real hardware, on a GPU, at ~140 fps:
> *"The port does no blur animation at all! I cannot discern if there is any
> animation at all. The logos just switch without the animation."*
## Measured, not paraphrased
Filmed from a **real boot** at 0.05 s (`--film`), then per-frame change measured
with [`tools/motion-census`](../../tools/motion-census):
| | |
|---|---|
| splash moves | **1.30 s of 7.95 s — 16.4 %** |
| publisher splash | 0.30 s of motion, then **3.20 s frozen** |
| developer splash | 0.35 s + 0.25 s, then **2.40 s frozen** |
| distinct luma states in 7.95 s | **26** |
A 45-unit build-in cannot be drawn in 26 states, and a fade does not hold one
picture for 3.20 s. **This is a switch with a flicker on either side.**
The frame counter says 24.8 fps achieved. Both are true: the port is *drawing*
25 times a second and *changing* almost never.
## 🔴 Why three instruments all said it was correct
This is the part that matters more than the bug, because it is the fourth time
this shape has cost a milestone.
| instrument | what it proved | what it could not see |
|---|---|---|
| **frozen sweep** (`--time=`, 3 units a step) | the renderer CAN draw pose *N* | whether the poses are ever drawn **in sequence, while running** |
| **settled comparison** (0.01 % against the capture) | the resting pose is right | a screen frozen 84 % of the time matches a settled reference **perfectly — that is what frozen means** |
| **achieved-fps counter** | frames are being drawn | drawing the **same pixels** 25×/s scores identically to animating |
> **Every one measured throughput or a pose. Not one measured CHANGE.**
That is why the port could write *"the companion quads are drawn, verified by a
frozen sweep"* and be simultaneously right and useless: the sweep drives the
clock by hand. It is the same defect as `InputEventAction` bypassing the input
map — **the instrument sat below the thing that was broken**, so the thing that
was broken could not appear in it.
`tools/motion-census` exists to close this class. It measures change and nothing
else, and its `--selftest` proves it separates a fade (97.4 % moving) from a
switch (2.6 %) from a frozen film (0.0 %) — because a detector that cannot tell
those apart would report the same green line on all three.
## What both agents do now
**Nothing else.** Not the clock rate, not the plate, not blend, not audio. This
first.
### Port
1. **Reproduce it** with `--film` + `motion-census` before changing anything, and
quote the numbers. If your run does not reproduce 16.4 %, say so — the
disagreement is then the finding.
2. **Find why the clock does not advance the poses.** Candidates, unranked and
none established: the keyframe interpolation returns the same pose for a
range of *t*; `rest()`/plateau logic snapping to an endpoint; the group clock
not integrating; interpolation between keyframes not happening at all
(nearest-keyframe rather than lerp); the screen advancing by *keyframe index*
instead of by time.
3. **Every fix is gated by a film**, never by a still. A change that improves a
settled frame and leaves the film at 16 % has not fixed this.
4. `motion-census` goes into `check-all`, so a future regression fails a check
instead of waiting for a human.
### Decoder — **map the whole graphics pipeline, end to end**
The human's instruction, in their words: *"get the whole graphics pipeline, from
the xex/pe + the disc files to the final screen displayed, and take Xenia Canary
processing into account too."*
So: one continuous account, each stage with evidence and each labelled by the
instrument that produced it —
```
disc bytes → RATC/T8aD decode → what the GAME CODE does per frame
→ the draw calls it submits → Canary's own processing
→ the presented frame
```
Specifically, and none of it inferable from a file alone:
* **The game's per-frame update.** Which code advances a UI group's clock, in
what units, and what it does *between* keyframes — does it interpolate, or
hold to the next key? That single question decides whether the port should
lerp at all. It is in the image; find the function.
* **What the game submits per frame during the splash** — the draw list frame by
frame, not one settled frame. If the alpha changes, it changes *somewhere*
observable: a vertex colour, a PS constant, a blend factor, a texture swap.
**Name which, with the per-frame series.**
* **What Canary does to it.** Present cadence, any resolve/scaling/gamma between
the guest's draw and the pixels a capture records. A capture is evidence about
*Canary's output*, and the difference between that and the guest's intent has
bitten this corpus before (the `kernel_display_gamma_type` entry).
⚠️ **Deliver a per-frame SERIES, not a settled value.** Follow
[`TEMPORAL-VERIFICATION.md`](TEMPORAL-VERIFICATION.md): film it, align by
content, report ordering/counts/durations. The port needs to know what the
alpha *trajectory* is, and a single frame cannot carry one.
## And this is a refutation the port should record against itself
`BLOCKED.md` H2 currently reads ✅ **ANSWERED**, on the strength of the frozen
sweep. The mechanism half stands — the blur is a baked companion texture, that
is decoded and correct. **The behaviour half does not**: the port draws those
quads and does not animate them, so *"the companions are drawn"* was true and
did not mean what the row used it to mean.
---
## What is STILL OPEN after the sign-off
The logos are done. These are not, and none of them blocks a milestone gate:
| | | owner |
|---|---|---|
| **H1** | Does a held direction **repeat** in the menus, and at what rate? One step per deflection stays authored. The 61 % arm threshold is decoded and adopted; the 0.11 hysteresis gap is still authored. | Decoder |
| **H3** | The `PRESS Ⓐ` plate. All four named causes are dead and the port measures fractionally **early**, so what the human saw is **unattributed** — deliberately not closed green. ⚠️ Worth re-asking now: the animation fix changed what the whole boot looks like, so the original observation may simply no longer reproduce. | both |
| **pipeline** | The end-to-end graphics account — disc → decode → the game's per-frame update → submitted draws → Canary's processing → the presented frame. Cut short by the sole-focus order and **still the right work**: it is what would let the port know whether its ramp *duration* matches the game rather than only its own declared keyframes. | Decoder |
**P5's gate is "a human clicks through it" and has NOT been claimed here.** The
human has signed off the *logos*, and separately confirmed that Ⓐ, the stick and
the submenus work. Nobody has said the milestone is met, and an agent must not
say it on their behalf.

**Set by the human, 2026-09-02, from what actually worked.** The splash bug had
sat through a whole milestone. Scoped to *one* question — *does it animate?* — it

split it, and pick one.

* **what the human looks at**, and what pass and fail each look like;
* **what it does NOT cover** — the neighbouring thing you are deliberately not
fixing, so nobody reads a narrow pass as a broad one.
Then: **do that one, hand it over, and stop.** Do not run ahead into the next
unit while the first is unverified — an unverified fix underneath a second change
is how a regression becomes two-variable and unattributable.
⚠️ **The bar is a HUMAN check, not a green tool.** Three instruments passed a
frozen screen. A tool answers *did my change do what I intended*; only the person
answers *is it right*. When a unit needs a look, say so plainly and say what to
look at — an ask that is buried in a document nobody opens is not an ask.
📌 And this bounds the writing, which has been the other failure: the retro found

You are the **Decoder**. Answer the open questions the Godot menu port is
blocked on, one at a time.
## 🔴 CURRENT FOCUS, set by the human 2026-09-01: THE LOGO SPLASHES, EXACTLY
## 🔴🔴 SOLE FOCUS, 2026-09-02: **THE TITLE'S ANIMATION TIMING — F5 and F6, nothing else**
**Work only these two.** Not the pipeline, not the audio mix, not the repeat
rate — they stay queued in
[`PLAYTEST-2026-09-02-menus.md`](PLAYTEST-2026-09-02-menus.md).
> *"Let's have the agents focus on this item and only this only."*
**F6 first** — it is the one with a lead. A human reports that the title's
sweeping white glow (**`ptloop01` / `ptloop02`**, the blue PCB-like lines) **only
starts when the plate appears** in the real game, while the port starts it
earlier. `title.json` declares those elements at `t = 0, 70, 100, 238, 250` and
the plate reaches full alpha at **`t = 236`** — with `pteff02` keyed at exactly
236 and `ptlogo_back2eff`/`ptcopyright` at 238. **236238 is a synchronisation
point in the declared data and a human just reported a behaviour change there.**
⚠️ `238…250` may equally be an **exit ramp** (`ptcopyright` uses that shape and
starts nothing), and the sweep lives in a nested `.rat` leaf with its own
timeline. Establish which of the two the human is watching.
**F5 second** — does Ⓐ **snap** the title to finished, or **accelerate** it? The
human says they cannot tell, and is right that they cannot: a three-frame
acceleration and a one-frame cut look identical to an eye. Two routes, and they
should agree: a **per-frame capture** (an acceleration shows intermediate alphas,
a cut shows none) and **the code** (assigning a target time and raising a rate
multiplier are different instructions). Their *"looks more like a snap"* is a
**prior, not a result** — say so if the measurement disagrees.
### And split it before you start
**Read the new "Work in units a human can check in a minute" section of
[`PROTOCOL.md`](PROTOCOL.md).** The human's diagnosis is that whole missions have
been too big to hold. Break even F6 down, write the question and the
look-at-this-and-you-will-see before working, do one, hand it over, stop.
## ✅ THE LOGO SPLASHES ARE DONE — signed off by the human, 2026-09-02
> *"Looks good! Cannot notice any obvious difference from the actual game.
> Mark logos as done."*
**The sole-focus order is lifted.** The port's defect was `pose_at` assigning the
settle instant rather than clamping to it; your per-frame measurement of the real
game (28 distinct alphas over 28 consecutive presents, modal steps 3 and 14
against predicted 2.87 and 14.13) is what let their fix be checked for *shape*
and not merely for motion. That is the pairing this team is for.
### 🔴 The pipeline work is STILL THE RIGHT WORK — continue it, at normal priority
It was cut short by the sole-focus order, and it remains the thing that decides a
question the port cannot answer about itself: **the port matches its own declared
keyframes; nobody has established that its 60 units/s matches the game.** The
ramp is right in shape and unverified in duration.
So carry on with the end-to-end account, unchanged in substance:
```
disc bytes → RATC/T8aD decode → what the GAME CODE does per frame
→ the draw calls it submits → Canary's own processing
→ the presented frame
```
The three load-bearing questions stand, and the first is now the most valuable:
1. **The per-frame update** — which function advances a UI group's clock, in what
units, and **what it does between keyframes**. The port interpolates
piecewise-linearly across declared segments and your capture agrees; the
remaining gap is the *rate*.
2. **What is submitted per frame** during a screen's build-in, as a series.
3. **What Canary does to it** before a capture records it — present cadence,
resolve, scale, gamma.
### 🔴 Four asks from the 2026-09-02 menu play-test — [`PLAYTEST-2026-09-02-menus.md`](PLAYTEST-2026-09-02-menus.md)
P5's gate is **met** (a human walked the menus). These came out of the same
session, and three of the four are yours. They are ahead of the pipeline work
because the port is blocked on two of them.
1. **F1 — MEASURE THE MENU REPEAT RATE.** The human watched the real game: a held
direction **repeats**, *"at a medium pace… slow enough to see which item is
selected"*. That settles the existence half of H1 against our authored
one-step-per-deflection. Two numbers, and the port will not move without
them: the **initial delay** before the first repeat, and the **repeat
interval** after it. Frames between cursor moves at a stated present rate — a
count, not a stopwatch. Also: does the d-pad differ from the stick? Does it
accelerate while held, or stay flat?
2. **F2 — IS THE AUDIO MIX ON THE DISC?** The SFX are too loud and there is **no
gain value anywhere** in the export; `confirm` peaks at 0.0 dBFS and sits
3 dB above the music in mean. A cue record commonly carries a volume beside
its wave index, and you already decoded `sub_821C5580` playing cue 1103. If
per-cue or per-bus gain is there it is **decoded** and nobody has to choose.
If it provably is not, say so with reach.
3. **F3 — WHAT DOES THE TITLE PLAY?** A human says something is missing there.
Which cue, if any, does the title screen play, and is there a **sting** when
the plate appears or when Ⓐ is accepted? ⚠️ A negative needs a positive
control (R4): show the method finding the *menu's* cue before concluding the
title has none.
4. **F4 — WHAT DOES Ⓐ DO TO THE CLOCK?** In the real game, Ⓐ during the title
build-in **reveals the plate immediately** — so the boot takes three presses:
skip video, reveal plate, accept plate.
🔴 **This is a test of `clock: "shared"`.** The title is two composited builds
— build 4 the artwork (finishes `t≈118`), build 2/3 the plate (full alpha
`t=236`) — and the port's `authored/flow.json` runs them on **one** clock
started together. That premise is **authored**, and the port's own
`plate-arrival-halves.md` calls it *"not falsified… not confirmed to better
than ~20 %"*, with an unresolved anchor disagreement inside one binary
(`t=118` from the reconciliation, `160` from `settle_time()`).
The discriminator is observable: **press Ⓐ early, while the wordmark is still
building in, and watch the ARTWORK, not the plate.**
| if Ⓐ … | the artwork |
|---|---|
| advances the shared clock | **snaps** to finished |
| only forces the plate visible | **keeps animating** its remaining build-in |
📌 It is also a **cheap second route to the plate-arrival question** — a press
that skips to the plate says where the game thinks the plate belongs — and a
third input the boot title accepts, narrowing `REFUTED.md`'s *"any title after
the first refuses input"* further.
⚠️ Deliver a **series, not a settled value** — see
[`TEMPORAL-VERIFICATION.md`](TEMPORAL-VERIFICATION.md), and note that the port's
whole defect was invisible to three instruments that each measured a pose or a
throughput rather than a change.
## Previous sole focus, 2026-09-02 — the order, kept for the method
A human on real hardware: *"the logos just switch, there is no animation."*
Measured from a real boot — **the splash moves 1.30 s of 7.95 s (16.4 %)**, the
publisher logo frozen **3.20 s**, and the whole thing takes **26 distinct luma
states**. The port draws the right quads in the right places and never moves
them.
Your half is not the port's bug. It is that **nobody can say what the game does
between keyframes**, so nobody can say what the port should be doing.
### The deliverable, in the human's words
> *"Get the whole graphics pipeline, from the xex/pe + the disc files to the
> final screen displayed. Take Xenia Canary processing into account too."*
One continuous account, each stage carrying its evidence and its `⟨instrument⟩`:
```
disc bytes → RATC/T8aD decode → what the GAME CODE does per frame
→ the draw calls it submits → Canary's own processing
→ the presented frame
```
Three questions that are load-bearing and none answerable from a file alone:
1. **The per-frame update.** Which function advances a UI group's clock, in what
units, and **what does it do BETWEEN keyframes** — interpolate, or hold to the
next key? That single answer decides whether the port should lerp at all. It
is in the image. Find it.
2. **What is submitted per frame during the splash** — the draw list frame by
frame, not one settled frame. If alpha changes it changes *somewhere*
observable: a vertex colour, a PS constant, a blend factor, a texture swap.
**Name which, and give the per-frame series.**
3. **What Canary does to it** — present cadence, and any resolve, scale or gamma
between the guest's draw and the pixels a capture records. A capture is
evidence about *Canary's output*; the gap between that and the guest's intent
has bitten this corpus before (`kernel_display_gamma_type`).
⚠️ **Deliver a SERIES, not a settled value.** Follow
[`TEMPORAL-VERIFICATION.md`](TEMPORAL-VERIFICATION.md): film it, align by
content, report ordering and counts and durations. The port needs the alpha
*trajectory*; a single frame cannot carry one.
[`../../tools/motion-census`](../../tools/motion-census) measures change and
nothing else — use it on your own captures too, and note that three of the
port's instruments passed a frozen screen because each measured throughput or a
pose rather than change.

You are the **Port**. Build the Godot menu shell, one milestone at a time.
## 🔴 CURRENT FOCUS, set by the human 2026-09-01: THE LOGO SPLASHES, EXACTLY
## 🔴🔴 SOLE FOCUS, 2026-09-02: **THE TITLE'S ANIMATION TIMING — F5 and F6, nothing else**
**Work only these.** Not the repeat rate, not the audio mix, not P7 — they stay
queued in
[`../agents/PLAYTEST-2026-09-02-menus.md`](../agents/PLAYTEST-2026-09-02-menus.md).

**F6 — the title's sweeping white glow starts too early here.** A human watching
the real game reports that the glow travelling along the blue PCB-like lines
(**`ptloop01` / `ptloop02`**) **only begins when the plate appears**; the port
starts it before. **This is the Decoder's to establish and yours to implement**
do not choose a start time. What you *can* do now without an answer: determine
exactly **what your renderer currently uses** to start that sweep, so that when
the answer lands the change is one line and not an investigation.
**F5 — does Ⓐ snap or accelerate the title?** The Decoder is measuring it. Until
they answer, **do not implement Ⓐ#2** — a snap and a speed-up are different
behaviours and picking one is exactly the guessing that has cost this project.
### And split it before you start
**Read the new "Work in units a human can check in a minute" section of
[`PROTOCOL.md`](PROTOCOL.md).** The human's diagnosis is that whole missions have
been too big to hold — the splash sat through a milestone, then took a day once
scoped to *does it animate?*. Break the work down, write the question and what
the human should look at **before** working, do one unit, hand it over, and stop.
Do not stack a second change on an unverified first.
## ✅ THE LOGO SPLASHES ARE DONE — signed off by the human, 2026-09-02
> *"Looks good! Cannot notice any obvious difference from the actual game.
> Mark logos as done."*
**The sole-focus order is lifted. Return to your milestones.** The fix was
`pose_at` assigning the settle instant instead of clamping to it — and that same
line manufactured the false green, because the capture harness was photographing
t ≈ 2 units and it *looked* settled only because everything did.
📌 **Keep the lesson, it outlives the bug.** Three instruments passed a frozen
screen: a frozen sweep drives the clock by hand, a settled comparison is
*defined* to pass on a frozen screen, and an achieved-fps counter counts frames
drawn rather than frames different. Ask of any new check: **what would this still
report if the feature were entirely absent?** `tools/motion-census` exists for
exactly that question; keep it in `check-all`.
## ✅ P5's GATE IS MET — the human walked it, 2026-09-02

`PORT-MISSION.md` is updated. The NEW GAME gap is accepted as-is — they know the
difficulty select comes first in the real game and that the port announces it.

## Previous sole focus, 2026-09-02 — RESOLVED, kept for the method
> *"The port does no blur animation at all. The logos just switch."*
Measured from a real boot, not paraphrased: **the splash moves 1.30 s of 7.95 s
(16.4 %)**, the publisher logo is **frozen for 3.20 s**, the developer logo for
2.40 s, and the whole 7.95 s takes **26 distinct luma states**. A 45-unit
build-in cannot be drawn in 26 states.
🔴 **Your three instruments all passed this, and the reason is the point:**
* the **frozen sweep** drives the clock by hand — it proves the renderer can
draw pose *N*, never that the poses are drawn in sequence while running;
* the **settled comparison** scored 0.01 % — a screen frozen 84 % of the time
matches a settled reference *perfectly*, because that is what frozen means;
* the **achieved-fps counter** counts frames DRAWN — drawing the same pixels
25×/s scores exactly like animating.
**Every one measured throughput or a pose. None measured CHANGE.** Same shape as
`InputEventAction` bypassing the input map: the instrument sat below the thing
that was broken.
**Use [`tools/motion-census`](../../tools/motion-census)** — it measures change
and nothing else, and its `--selftest` proves it separates a fade from a switch
from a frozen film. Order of work:
1. **Reproduce first**, with `--film` + `motion-census`, and quote the numbers.
If you do not get ~16 %, that disagreement is the finding — say so.
2. **Find why the poses do not advance.** Unranked, none established:
interpolation returning one pose across a range of *t*; `rest()`/plateau
snapping to an endpoint; the group clock not integrating; nearest-keyframe
instead of lerp; advancing by keyframe *index* rather than by time.
3. **Every fix is gated by a FILM, never a still.** A change that improves a
settled frame and leaves the film at 16 % has not fixed this.
4. Put `motion-census` in `check-all` so the regression fails a check instead of
waiting for a human.
⚠️ **And record the refutation against yourself.** `BLOCKED.md` H2 reads ✅
ANSWERED on the strength of the frozen sweep. The *mechanism* half stands — the
blur is a baked companion texture, decoded and correct. The *behaviour* half does
not: you draw those quads and do not animate them, so "the companions are drawn"
was true and did not mean what the row used it to mean.

# F6 unit a — what the port currently uses to start the title sweep
**Status:** ✅ answered. **No behaviour changed** — this unit exists so that when
the Decoder says *when* the glow should start, the edit is one line.
Port at `937f055`, 2026-09-02.
## The answer, in one line
`port/scripts/screen_view.gd:684`
```gdscript
var t := leaf_time_units if leaf_time_units >= 0.0 else time_units
```
**That is the whole start mechanism, and it is not a start mechanism.**
`leaf_time_units` is set in exactly one place — `boot.gd:359`, the `--leaf-time`
diagnostic flag — and is `-1.0` on every real boot. So the travelling glow runs
on `view.time_units`, the title screen's own clock, which `_advance` sets to
`0.0` when the title is raised. **Zero offset, no gate.**
## 🔴 And the obvious gate does not exist
The natural reading — mine, before checking — is that the parents gate it:
`ptloop01`/`ptloop02` declare `0:0 70:0 100:255 238:255 250:0`, invisible until
t=70. **That is not what happens**, because what reaches the screen is the LEAF,
and `screen_view.gd` records as decoded that *"the leaf runs on its OWN timeline
and the parent's alpha is NOT multiplied in"*. The parent ramp gates nothing.
The leaves' own declarations:
| leaf | alpha | x position |
|---|---|---|
| `pteff03` | **`0:255`** 150:128 540:255 600:255 | 639 → 39 (t=150) → 1521 (t=540) |
| `pteff03a` | 0:0 150:128 630:255 720:255 | 1721 → 1111 (t=150) → 839 (t=630) |
**`pteff03` is at full alpha from title t=0** and is travelling from t=0. It
clears the left edge (sprite is 399 wide) at around t≈60 and is well inside the
frame by t=150.
The plate arrives at **t=214236**. So the port starts the sweep roughly
**150+ units ≈ 2.5 s early** — which is the size and the direction of what the
human reported.
## Corroborated on a film, not only read
Filmed a real boot at 0.05 s and measured frame-to-frame change in the title art
band `1280x420+0+90`, which **excludes the plate's own rectangle** (y 550600) so
the plate cannot be what registers:
```
view_units 22 54 69 86 118 134 214 341 406
delta 31.8 39.9 30.8 9.4 12.6 0.2 0.2 0.1 0.4
```
Motion is heavy through the build-in and the band is quiet by t≈134 — consistent
with `pteff03` having already crossed the measured band and with the coarse
resize washing a thin glow out. **The film neither adds to nor contradicts the
declaration; the declaration is the evidence here.**
## Where the sweep actually is, computed from the leaf's own translation
The port positions the leaf **from the leaf's own clock** — it does not draw the
parent's pose and ignore the translation. Sprite 399 wide on a 1280 screen:
| t | 0 | **61** | 70 | 100 | 150 | **236** | 250 |
|---|---|---|---|---|---|---|---|
| `pteff03` x | 639 | **395** | 359 | 239 | 39 | **305** | 361 |
| `pteff03a` x | 1721 | 1477 | 1436 | 1314 | 1111 | 762 | 705 |
**`pteff03` enters the frame at t=61 and is mid-screen at t=305 when the plate
reaches full alpha at t=236** — visible and travelling for ~175 units ≈ 2.9 s
before the plate. `pteff03a` enters much later.
## 🔴 The open question in this file sits exactly inside F6's window
`screen_view.gd` flags its own limit on the leaf-vs-parent alpha decode:
> *"Every observation behind this has parent alpha 0, so 'the leaf wins' and 'the
> parent is ignored because it draws nothing' are NOT separated. **A capture
> during t=100…238 would separate them.**"*
The parent is non-zero exactly on `t=100…238`, and the plate arrives at 236. So
that unresolved ambiguity is **the same interval F6 is about**, and it is
load-bearing for the first stretch: the parent ramps 70→100, so applying it would
hide the sweep until t=70 and dim it to t=100, while the port shows it at full
alpha from t=61.
That accounts for ~40 units of the earliness. **It does not account for the other
~175**, which is the leaf clock starting at title t=0 with no offset.
📌 **One capture in `t=100…238` would settle both** — F6's start time and the
leaf/parent alpha rule — rather than two.
## What changes when the answer lands
A start time is an **offset**, and `leaf_time_units` is an absolute override —
they are not the same field. The one-line edit at 684 becomes a subtraction, fed
by one authored value. Nothing else moves.
## What this does NOT do
* **It does not choose a start time.** That is the Decoder's, and this unit was
scoped to exclude it deliberately.
* It does not touch the glow. A boot looks exactly as it did.
* It says nothing about whether the *speed* or the *path* is right — only when it
begins.
---
# 🔴 Unit b, HELD: the parent-alpha refutation may be right, but its identification step cannot carry it
**Status:** ⏸️ **the renderer is NOT changed.** The Decoder's
`f6-unit2-parent-alpha-multiplies.md` refutes `screen_view.gd`'s *"the parent's
alpha is NOT multiplied in"* using a bound. The bound's shape is sound and its
premise checks out against this export. **The step that assigns the measurement
to an element does not.**
## The premise holds
`pteff03`'s leaf declares `0:255 150:128 540:255 600:255`**minimum 128**,
confirmed off `export/screens/title/title.json`. A drawn alpha below 128 cannot
come from that leaf alone. That part is right.
## 🔴 But the two strips are the SAME SIZE, so size cannot say which is which
The identification is stated as *"by size against the corpus's independently
measured AABB height of 1134 px"*. Measured off this export:
| sprite | dimensions | leaf alpha range | travel |
|---|---|---|---|
| `pteff03` | **399 × 180** | **128 … 255** | left → right (639 → 1521) |
| `pteff03a` | **399 × 180** | **0 … 255** | right → left (1721 → 839) |
**They are byte-identical in size**, which is consistent with the two reported
rows measuring `1.38 × 3.15` and `1.39 × 3.15` — a 0.7 % difference. Size
separates the sweeps from everything else on the screen; it cannot separate them
from **each other**, and that is the distinction the argument needs.
## Why it matters — the assignment flips the conclusion
The quoted row that reaches **8** is the one the argument leans on. But
`pteff03a`'s leaf alpha floors at **0**, not 128, and ramps `0 → 128` across
t=0…150. Values of 8, 24, 33, 50 … are exactly what **that leaf alone** produces.
So if the 8-row is `pteff03a`, the bound is satisfied with no parent at all.
⚠️ **And the conclusion may still be correct via the OTHER row.** The row
reported as `16 41 67 91 116 128 129 130 131` contains values below 128 *and* a
dense cluster at 128131 — the signature of `pteff03`'s floor. If that row is
`pteff03`, then 16 < 128 refutes no-multiply exactly as claimed. **The finding
may be right and the cited row wrong.**
## The discriminator is free and already in their capture
The two leaves travel in **opposite directions**: `pteff03` left→right,
`pteff03a` right→left, separated by ~1 000 px for most of their run. One frame
pair settles it. Nothing needs re-capturing.
## ✅ Resolved: the discriminator worked, and MY proposed repair was wrong
The Decoder ran the travel-direction check on the capture they already had:
```
1.38x3.15 n=1140 x centre -1.690 -> +0.500 LEFT->RIGHT
1.39x3.15 n= 614 x centre -1.685 -> +0.495 LEFT->RIGHT
```
**Both rows travel the same way, so both are `pteff03`** — the 0.7 % size
difference is per-frame rounding splitting **one** element across two keys.
`pteff03a` is not in the capture at all.
🔴 **So my "the finding may still be correct via the OTHER row" does not apply —
there is no other row.** The identification was broken a third way that neither
of us named: not two elements confused for each other, but one element counted
twice. I was right that size could not carry the assignment and wrong about what
the assignment actually was.
⚠️ And the part I could not see from here, which is the larger one: the quoted
`8 24 33 50 58 …` were the nine **lowest distinct** values, not a series — a
tail, presented in a shape that reads as a ramp. **14 sub-floor samples out of
1754.** The bound survives in shape and collapses in weight: one sample below 128
is still unexplainable by a leaf flooring at 128, but 14 of 1754 is where a
grouping slip or a partial frame would show up.
**Status: 🟡 not refuted, not established.** The next unit is a re-read of data
already on disk — the same capture as a *series* across t=70…100, where a
multiplying parent must ramp on nearly every frame rather than in 14 stragglers.
That unit is the Decoder's and has not been run.
## What the port does about it: nothing yet
Adopting a decode whose element assignment is unresolved is how this project has
been burned before — and the port would be changing a renderer rule on it.
`screen_view.gd` keeps its current behaviour until the row is identified by
travel direction. **This is not scepticism about the conclusion**, which the
port's own flagged limit predicted would fall this way; it is about which row.
---
# 📌 What was actually holding this up: we both picked the wrong observable
The human asked what was blocking us and whether the approach needed revising.
**It did, and the diagnosis is short: two agents spent three exchanges on ALPHA
while the answer sat in a POSITION series neither of us compared to anything.**
## The arithmetic that should have been step one
The Decoder's capture reports the sweep's x-centre running `1.690 → +0.500`.
Read as NDC (`x_ndc = 2·x_px/W 1`, **an assumption, stated as one**):
| | ndc | centre px | implied leaf t |
|---|---|---|---|
| first sample | 1.690 | 441.6 | **0.5** |
| last sample | +0.500 | +960.0 | 349.9 |
| **declared at leaf t=0** | **1.687** | **439.5** | — |
**A 2 px agreement on a 2 160 px travel.** So the game's sweep begins travelling
at leaf t≈0, from off-screen left — **the same as the port.**
🔴 **That contradicts my own earlier framing on this page**, which attributed
~135 units of the earliness to "the leaf clock starting at title t=0 with no
offset". If the game's leaf clock also starts at 0, that is not a defect and F6
is a **visibility** question — alpha, or draw order, or something not yet named —
rather than a clock question. I am flagging it rather than rewriting the section:
this rests on two numbers relayed in a message, which is exactly the thing that
should be read from the repository instead.
## Why alpha was the wrong tool, stated generally
| | alpha | position |
|---|---|---|
| dynamic range | 8 bits, quantised | **2 160 px** |
| shape | non-monotone, ramps and holds | **monotone** |
| failure mode that bit us | a 14-sample tail out of 1754 looks like signal | a wrong shape raises the residual |
| yields the clock? | no | **origin AND rate together** |
**When something moves, its position carries the clock and its alpha carries
almost nothing.** Neither of us reached for a trajectory comparison because
neither of us had one.
## So: `tools/port/fit-trajectory`
Solves `x_measured(frame) ≈ declared(t0 + rate·frame)` for the pair, and reports
the **residual**, which is the part that matters: it says whether the model was
right at all, where a value-at-an-instant never can.
Its `--selftest` runs both directions — recovers a known clock from a synthesised
series to 0.09 px, and **rejects** a wrong-shape series at 81.9 px against a 20 px
bar — because a fit that cannot fail is a curve-fitter, not a measurement. Wired
into `check-all`.
⚠️ It fits a **constant** rate. A stalling guest clock or uneven capture drops
raise the residual rather than being absorbed, which is deliberate.

## The original section, kept for its shape
## First, the correction: my refutation was right in outcome and WRONG in its reason
I challenged the Decoder's by-size identification on the ground that *"both
sweep sprites are 399×180, so size cannot separate them"*. **That was wrong.** I
compared the source PNGs and never looked at the leaf declarations:
| leaf | sprite | declared scale | **drawn height** |
|---|---|---|---|
| `pteff03` | 399×180 | `[100, 600]` | **1080 px** |
| `pteff03a` | 399×180 | `[100, 800]` | **1440 px** |
The *drawn* quads differ by a third, which is exactly the 3.15 vs 3.62 NDC the
Decoder was separating by. **Size distinguishes them fine.** The hold was still
correct and the check I asked for still found a real defect — but it found a
different one (one element double-counted, and a set presented as a series), and
my stated reason did not survive. Recorded because a right answer reached by a
wrong argument is the kind that gets cited later for the wrong reason.
## And it makes the real finding sharper
Because size *does* separate them, the Decoder's line — *"`pteff03a` does **not**
appear in this capture at all"* — is well-evidenced rather than incidental. They
looked for a distinct size and found nothing.
**The port draws it.** Asked directly, at three instants:
```
t=120 drew 9: ptbase2, pteff03, pteff03a, pteff04, ...
t=180 drew 10: ptbase2, pteff03, pteff03a, pteff04, ...
t=240 drew 10: ptbase2, pteff03, pteff03a, pteff04, ...
```
`pteff03a` is on screen in the port from t≈108 (it crosses x=1280 there) until
t≈521, travelling **right-to-left** at 800 % vertical scale while `pteff03` runs
left-to-right at 600 %. The capture covers that window and contains only
`pteff03`.
> ~~**So the port appears to render a second light sweep, larger and travelling
> the opposite way, that the game does not draw during the title build-in.**~~
> ❌ **False.** The game draws both, batched into one eight-vertex draw.
⚠️ **Absence in one capture is not absence in the game**, and this is one
capture, read by one probe, identified by size. It is a lead, not a finding. But
it is the first thing in F6 that is *visible*, *port-side*, and *checkable by a
person in seconds* — which is what this whole exchange has been missing.
## What did NOT work, recorded so nobody repeats it
I tried to isolate the two sweeps visually by differencing title frames at
several `--time` values. **It failed and the output is not evidence**: at those
instants the whole title is still animating — logo, effects, copyright — so the
difference is the entire screen rather than the sweeps. Frame-differencing
isolates motion only when everything else is still, and during a build-in nothing
is.
## The unit, and it is one question for a person
> **On the real game's title screen, is there ONE light streak sweeping across,
> or TWO travelling in opposite directions?**
Pass for the port as it stands: two. If the game shows one, `pteff03a` is drawn
here and should not be — and an extra glow arriving at t≈108 is a very good
candidate for *"the glow starts too early"*.
**Not covered:** the start time of `pteff03` itself, which is still open; and the
parent-alpha question, still 🟡.
---
# ❌ Unit d — the "variant link" explanation, raised and killed in one pass
The Decoder's second candidate for why the game submits `ptloop01` and not
`ptloop02` was *"a focus/variant link means only one of the pair is ever
active"*. **That is answerable from the export, and the answer is no.**
## What looked like a smoking gun
`ptloop01` carries **`opt_link = "ptloop02.rat"`**, `ptloop02` carries none, and
it is the only linked element on the title screen. The field is exported straight
from `el.focus_link` (`crates/sylpheed-export/src/screen.rs:622`), and
**`port/scripts/` never reads it.** An ignored variant link would have explained
the extra sweep exactly.
## ❌ And it is not a variant link
Surveying `opt_link` across the whole export splits it into two populations:
| target | example | is the target also a top-level element? |
|---|---|---|
| `*f.rat` | `ptbtn00 → ptbtn00f` | **no** — variant only |
| everything else | `ptloop01 → ptloop02` | **yes** — both are drawn |
And the second population **chains across unrelated element kinds**. On
`main_menu`:
```
index 3 ptloop01 -> ptloop02.rat
index 4 ptloop02 -> ptbtn01.rat
index 10 ptbtn01 -> ptbtn01f.rat
```
**A light sweep points at a button.** A variant selector cannot do that, so
`opt_link` is a chain pointer that happens to land on the focus variant when the
element is a button — which is why it was exported under the name `focus_link`.
> So the field does not select between `ptloop01` and `ptloop02`, and the port
> ignoring it is not what draws the extra sweep. **Candidate eliminated.**
## The smaller finding that survives
**`focus_link` is carrying two different things** and the exporter names it after
only one of them. The `*f` population is a variant; the rest is a chain. Nothing
depends on this today — the port reads neither — but the name asserts a meaning
the data does not support, and the next person to reach for it will reach for the
wrong one. Worth renaming when something actually needs it; not worth a
re-export on its own.
## Where that leaves F6
The lead is unchanged and unexplained: **the port draws `pteff03a`, the game's
capture never does** — now confirmed by an exhaustive scan of every tall quad in
1..2499 rather than a filtered subset. One of the two candidate causes is now
eliminated from the export side, which leaves the Decoder's first: a zero-alpha
skip suppressing the opening frames. ⚠️ That one does not obviously survive
either — it would explain `pteff03a`'s *opening* frames, not its whole run, and
its leaf reaches α=128 well inside the captured window.
**Nothing is deleted and the renderer is unchanged**, pending one five-second
human look: one streak, or two?
---
# Unit e — the port draws exactly TWO travelling lights, and the human reports more
The human, watching the real game: *"I think multiple, possible more than two…
The lights move on blue lines looking like PCB board lines. And frankly I cannot
tell if the game renders a light per line or uses a light that is shown around
multiple, close lines."*
That is a different question from the one both agents had been asking, and it is
worth having the port's own number first.
## Census of every element on the title that travels
| element | x travel | note |
|---|---|---|
| `ptlogo1` / `ptlogo2` (×3 instances) | 300 px | the **logo** sliding in, t=34…251 — not a light |
| **`pteff03`** (leaf of `ptloop01`) | **2 160 px** | left → right |
| **`pteff03a`** (leaf of `ptloop02`) | **2 560 px** | right → left |
Every other title element — `pteff00`, `pteff01`, `pteff02`, `pteff04`,
`ptlogo_back2eff` and `…eff1…5`, `ptlogoall_eff`, `ptlogoall_eff2`,
`ptcopyright`, `ptbase2`**declares no positional travel at all.** They fade in
and out in place.
> **The port renders exactly two moving lights.** The human describes multiple,
> possibly more than two, running along individual PCB traces.
## What that reframes
Both agents had been asking *when* the sweep starts. If the game's effect is a
population of small lights on separate traces and the port's is two full-height
streaks crossing the screen, then **the port may have the wrong effect
altogether**, and "starts too early" is what a wrong effect looks like to someone
who is not reading keyframes.
⚠️ **And it puts a limit on the capture result.** The Decoder's scan that found
`pteff03a` absent covered every quad **taller than 1.2 NDC**. Small per-trace
lights are far below that, so that scan cannot count them — it is exhaustive over
full-height streaks and silent about the population in question. `pteff03a`'s
absence stands (it would be 3.62 NDC); *"only one travelling quad exists"* does
not generalise beyond tall quads.
## ⚠️ A limit of this census
It reads **declared** keyframes. An element with a single keyframe shows as
"visible 0…0" here and is in fact held and drawn — `ptbase2`, the background, is
the obvious case. So the visibility column understates; **the travel column is
the load-bearing one**, and travel is what a moving light needs.
It also cannot see motion that is not positional — a scrolling UV, a texture
animation, or a shader would move light along a trace while declaring no travel
at all. **Nothing in this export declares such a thing**, but the port would not
know if the game did it that way, and that is now a live possibility rather than
a remote one.
## Not covered
Whether the game's lights are one-per-trace or one glow spanning several — the
human says they cannot tell, and it is the Decoder's screenshots to settle.
---
# 📌 What the withdrawal is worth, since the port lost nothing
Three of my own claims rested on `pteff03a` being absent and all three fall with
it: that the port renders a sweep the game does not, that this was "the first
thing in F6 that is visible and port-side", and — in a report to the human — that
"the port draws two, the game's capture has one." **The port draws two and so
does the game.** The census on this page stands unchanged; what changed is that
it now agrees with the capture rather than contradicting it.
**The one thing that made this free was refusing to act on it.** The evidence was
an exhaustive scan, from an agent with the oracle, corroborated by a mechanism
and by two candidate causes. It was still an *absence*, measured once, by one
reader — and the check I asked for was a human's look, not another measurement.
⚠️ **An absence is a claim about an instrument, not about the world.** A count of
zero says only that nothing got through the reader. Every positive result on that
same capture — the alpha decomposition, the press-vs-control comparisons, the
pulse ratio — is untouched, because those compare like with like on the same
quad. Only the absence compared a count against zero, and that is precisely where
a truncating reader is fatal.
📌 The Decoder notes this is the third time this corpus has been bitten by an
under-reading dump, and that `REFUTED.md` already recorded a draw carrying two
rotated parallelograms — **the general fact was written down before the reader
contradicted it.** Their cheap check is worth repeating here because it applies to
anything the port ever reads: *read one raw record in full before trusting any
count derived from it.* The batch size was printed on every one of those lines.
## 📌 And the same error recurred, which makes it a pattern rather than a slip
The withdrawn alpha bound on this page failed because nine values quoted as a
series were `sorted(set(...))[:9]` — the lowest distinct values, a tail wearing
the shape of a trajectory. The Decoder has since found the same thing in a second
finding: an implied-parent range quoted as 254.0256.9 turned out to be *the rows
they had printed*, every twentieth frame, standing in for a population whose real
first-cycle spread was 250.9260.5.
**Twice, and both times the output looked fine.** That is the tell: a summary
drawn from a subset does not look like an error, it looks like a result. The
conclusion survived on both occasions, so nothing here needs undoing — but a
conclusion surviving is not evidence the number under it was sound, and this port
has now inherited two numbers that were not.
⚠️ **Neither was reachable by reasoning**, which is the part worth keeping. In
both cases the argument was valid and the *inputs to the summary* were wrong. No
amount of re-reading the claim finds that; only re-running it does. It is the
argument for re-running over re-checking, and it is why the two findings flagged
as unverified above were re-run rather than defended.
---
# ❌ A refutation aimed at this renderer, measured and NOT landed
The Decoder raised it and could not test it from their side: *"if your renderer
runs both leaves on a single rate, the two strips stay locked together and drift
from the game by ~118 units per cycle, growing without bound."* The two leaves
declare **600** and **720** unit loops.
**Pre-registered, then measured on a real boot** via `--probe-leaf`. At a raw leaf
clock of 4873:
| leaf | span | measured `leaf_t` | `fposmod(4873, span)` |
|---|---|---|---|
| `pteff03` | 600 | **72.6** | 73 |
| `pteff03a` | 720 | **552.6** | 553 |
The port takes each leaf's span from **its own keyframes**`span = max(k.t)`
over `fe.keyframes` — so the two were never locked. **17 748 probe samples, title
clock reaching 9 745**, i.e. the sweep is still looping 162 seconds in.
## 🔴 Two false alarms of my own on the way there, both from the same mistake
1. **I used `--time` to ask a question about running behaviour.** It sets
`frozen`, which by design bypasses the `holding` clamp, so the title read as
*empty* past t=250 and I nearly reported the whole title vanishing. On a real
boot it does not: `settle_window` is `[160, 236, 198]`, the elements clamp to
t=198, and a filmed frame at `view_units 6733` shows the complete title.
2. **I read a probe stopping as the feature stopping.** Two runs ended at
u≈236 and I took that as the sweep dying at settle. It was the run ending —
without `--film` the boot exits sooner. With a film attached the same probe
reaches 9 745.
📌 Both are the frozen-sweep lesson wearing new clothes: *the diagnostic that
pins the clock cannot answer a question about the clock running*, and *an
instrument going quiet is not the subject going quiet*. The second is the same
shape as the Decoder's own absence-of-a-quad bug — a count of zero says only that
nothing reached the reader.
---
# ✅ Out-of-sample: what the port ships was in the passing half
The Decoder pre-registered six predictions and tested them on a fresh boot that
had no hand in deriving them. **Three failed.** Audited here against what this
port actually authors, and the answer is **nothing to change**:
| their prediction | fresh boot | does the port carry it? |
|---|---|---|
| leaf period ratio 1.200 | 1.1753 ✅ | **yes** — this is `rate = 0.5` |
| strip size ratio 1.333 | 1.3009 ✅ | yes, as element identity |
| pulse / sweep loop 0.100 | 0.0963 ✅ | yes, `looping_focus_records` 120 |
| pulse amplitude ≤3 levels | 8.73 🔴 | no |
| `ptcopyright` ramp ratio 0.733 | 0.550 🔴 | no |
| sweep leads plate 0.1380.141 | **0.0996** 🔴 | **no** — grepped, absent |
`authored/rendering.json` `leaf_clock` is `{start_units: null, rate: 0.5}` and
nothing else. No separation constant exists in `authored/`, `tools/port/` or
`port/scripts/`.
📌 **That split is not luck and is worth naming.** Everything the port adopted is
either **declared on the disc** (the parent gate, the 120-unit pulse loop, the
600/720 leaf periods) or **corroborated by three independent legs** (the rate).
Every failed prediction is a figure derived from *relationships between elements
measured in a capture* — the class with no declared counterpart, which
`check-authored-vs-declared` says out loud it cannot arbitrate. The rule "adopt
what the disc declares, or what three unrelated things agree on" selected exactly
the surviving half without anyone knowing which half that would be.
⚠️ And the Decoder reports that `check_labels.py` — offered last iteration as the
mechanism for capture-only labels — **fails its first independent test**: two of
its four checks fire on a third capture, having been validated on the two that
produced the labels. An instrument validated on its own training data. Nothing
here depends on it, but it is not a mechanism this port should lean on either.

# Four of five main-menu destinations are blocked on ONE hardcoded archive
**Status:** ✅ feasibility established, nothing changed yet. 2026-09-03.
## The gap, in player terms
| button | destination | today |
|---|---|---|
| NEW GAME | `DLG_SELECT_DIFFICULTY` → SELECT DATA → video | **jumps straight to the video** |
| LOAD GAME | `GP_SAVE_LOAD` | **dead** |
| TUTORIAL | — | **dead** |
| OPTIONS | `GP_OPTIONS` | **dead** |
| EXTRAS | `extras` | works |
All four are recorded in `authored/flow.json` as **measured destinations**
somebody drove the real game to them. They are `blocked` for one structural
reason, stated there: *"not a GP_TITLE build, so there is no screen file to go
to."*
## The cause is one line
`crates/sylpheed-export/src/main.rs` hardcodes `let archive = "dat/GP_TITLE.pak"`.
## And the reader already works on the rest
`examples/probe_archives.rs` runs the **existing** `ui_layout::is_build` over
every `.pak` on the disc. It decodes nothing new:
| archive | entries | builds |
|---|---|---|
| `GP_OPTIONS` | 26 | **14** |
| `GP_SAVE_LOAD` | 108 | **18** |
| `GP_DIALOG` | 140 | **105** |
| `GP_TUTORIAL` | 2 | **2** |
| `GP_TITLE` | 16 | 12 |
**24 archives contain UI screen builds. The exporter reads one.**
> So this is not blocked on the Decoder and needs no new format work. It is an
> exporter scope limit, and the exporter is the port's.
## Why this is worth doing before the queued items
Measured against *"if this is wrong, what does a player experience?"* — the
filter this port adopted after spending two rounds on a plate pulse that turned
out not to be a defect:
* **four dead menu entries** and a missing difficulty screen: a player hits them
immediately and three of them do nothing at all;
* the audio mix (F2): a player notices, but the menu still works;
* the repeat rate (F1) and the title track (F3): both blocked on measurement.
## ⚠️ What this does NOT establish
* **That the screens will render.** `is_build` says the record parses as a build,
not that its sprites resolve, its names are known, or its layout is complete.
`GP_HANGAR_ARSENAL` reports 390 builds and is squarely gameplay, out of scope.
* **Which entry is the difficulty dialog.** `GP_DIALOG` has 105 builds and none
of them is named yet; `DLG_SELECT_DIFFICULTY` is a name from the flow, not an
entry index.
* **That more screens are free.** Every screen the export gains is a screen
`check-all`'s comparisons iterate over, and screen names are authored per
archive+entry — unnamed screens need a naming decision, not just a loop bound.
## Next unit
Widen the exporter to **one** further archive — `GP_OPTIONS`, the smallest at 26
entries — as data rather than a second hardcoded constant, and see what actually
comes out. Not all four at once: 139 new screens arriving together would make any
regression unattributable.

# The OPTIONS menu tree exists, renders, and is named
**2026-09-03.** `GP_OPTIONS` joined `export_archives` and produced 14 screen
builds. All 14 render; all 14 are now named.
## What they are
| entry | name | English | | entry | name |
|---|---|---|---|---|---|
| 19 | **`options`** | **the root** — GAME / CONTROL / SOUND / SCREEN SETTINGS, BACK | | 21 | `options_jp` |
| 16 | `game_settings` | Auto-Save, View Point, Radio Log, Subtitles | | 18 | `game_settings_jp` |
| 4 | `control_settings` | Control Type, Throttle, sensitivities, Vibration | | 8 | `control_settings_jp` |
| 3 | `sound_settings` | Music / Movie / Voice / SFX Volume | | 5 | `sound_settings_jp` |
| 6 | `screen_settings` | Gamma Correction, R/G/B, NEXT PAGE | | 9 | `screen_settings_jp` |
| 7 | `screen_settings_page2` | White / Black Level Adjust, PREVIOUS PAGE | | 10 | `screen_settings_page2_jp` |
| 20 | `control_customize` | per-action key remapping | | 22 | `control_customize_jp` |
A clean EN/JP pair for every screen, which is itself a check: 14 builds, 7
pairs, no leftovers.
## How they were identified, and why that is stronger than usual here
**By the text the screen renders about itself.** Each was exported, drawn by the
port at rest, and read: the titles and row labels are legible.
📌 That matters because this project has been bitten three times by
identification via **position, size or ordinal** — the sweep strips confused by
size, the plate identified by screen position, `ptcopyright` mistaken for the
plate. A screen that renders the words `SOUND SETTINGS` above four volume rows is
not that kind of inference.
⚠️ **What it still does not establish:** which screen the *game* navigates to
from which. The tree above is read off content, so `control_customize` being
"reached from CONTROL SETTINGS" is a reading of its own legend
(`Ⓨ : Customize` on `control_settings`), not a measured transition. Wiring
anything beyond `main_menu → options` needs the real navigation.
## Not yet done
* **Nothing is reachable yet.** `main_menu` `ptbtn04` still has `goto: null`.
* **`po_pad_slider1` has no sprite** in the export and reports NOT DRAWN.
* **All 14 are `NEVER COMPARED`** by `verify-screen` — reported, not asserted;
both its allowance and the reference renderer were calibrated on `GP_TITLE`.
* The screens are static: no navigation, no focus movement, no value editing.
---
# ✅ OPTIONS is reachable — and navigation inside it is blocked on a kind
`main_menu` `ptbtn04` now has `goto: "options"`. Walked with the menu harness:
main_menu → ⬇⬇⬇ → Ⓐ → the OPTIONS root renders. Ⓑ backs out.
## ✅ RESOLVED — the rows move. `0x3003` is `0x3002` with the parent bit set
The Decoder decoded it disc-wide: **bit 0 of `kind` is the PARENT FLAG**, and it
carries no role information. Over every `.pak` in `dat/`, `kind & 1` agrees with
"has a parent" on **15 493 elements with zero disagreements**
(`docs/re/ui-kind-bit0-is-has-parent.md`). The OPTIONS rows are parented; the
main-menu buttons are not. Same record class.
So the detector now matches `0x3002 | 0x3003` — **two values listed, not a
mask**. `kind & 0xFFFE == 0x3002` would also catch `0x73002`/`0x73003`, 160
elements whose high bits nobody has decoded, silently and on screens neither
agent has seen.
**Impact measured before re-exporting, not after:** exactly two screens gain
buttons — `options` and `options_jp`, five rows each. No existing screen changes.
Verified by walking it: `main_menu` → ⬇⬇⬇ → Ⓐ → OPTIONS, then ⬇⬇ moves
`po_menu_btn2``po_menu_btn3` with the focus ring rendering on the highlighted
row.
📌 **The port was right to wait.** The rejected rule — "carries a focus record ⇒
menu item" — would have reached the same answer here by a second inference from
structure, and would have reclassified elements on screens nobody had looked at.
The field cost one question and needed no inference at all.
## The original section, kept for the shape of the block
The exporter's button detector is `kind == 0x3002 && !focused`. The OPTIONS rows
are **`kind_raw = 0x3003`**, so `role` comes out `unknown`, the export's
`buttons[]` is empty, and up/down move nothing.
| screen | element | kind | focus record | in `buttons[]` |
|---|---|---|---|---|
| `main_menu` | `ptbtn01` | `0x3002` | yes | yes |
| `extras` | `ptbtn11` | `0x3002` | yes | yes |
| **`options`** | **`po_menu_btn1`** | **`0x3003`** | **yes** | **no** |
**What `0x3003` means is not the port's to decide**, so the rule was not widened
here. The circumstantial case is strong — five rows, each carrying a focus
record, on a screen whose own text lists five options — and *circumstantial* is
precisely the standard that has cost this project three separate retractions.
Asked of the Decoder.
⚠️ A tempting alternative rule is "an element with a focus record is a menu item",
which fits both screens. It is still an inference about semantics from structure,
and it would silently reclassify elements on every screen in the export. Not
taken.
## The workflow cost this exposed, worth knowing before repeating it
**A screen name is authored data, but it only reaches the port through a full
re-export** — which re-transcodes both movies. Renaming one screen costs the
whole tree. Not worth fixing today; worth knowing before anyone plans a naming
pass.
## 🔴 And a genuinely dangerous mistake, recorded because it nearly cost the session
Killing a background check with `pkill -f "check-all"` matched **the container's
own entrypoint**, whose command line contains the loop prompt — and that prompt
mentions `check-all`. `pgrep` duly reported the process as still running after it
had stopped, and a `pkill -9` on that pattern could have killed the session
itself.
**Match a process by its actual `comm`, or list with `ps` and check, before
sending a signal.** A pattern that appears in your own instructions is not a
pattern that identifies a process.

Point it at a directory of PNGs captured in order during a REAL run — the port's
`--film`, or a capture harness's frame dump. It reports where the picture moves
and where it is frozen, plus how many distinct states it ever took.
Why this exists
---------------
🔴 A human played the port and said *"the logos just switch, there is no
animation at all."* Every check either agent had said the splash was correct.
Three instruments agreed, and all three were blind in the same way:
* a **frozen sweep** — step the clock by hand, render a still per unit. That
proves the renderer CAN draw pose N. It never runs the animation.
* a **settled comparison** — correlate the resting pose against a capture. A
screen that is frozen 84 % of the time matches a settled reference
perfectly; that is what being frozen MEANS.
* an **achieved-fps counter** — frames DRAWN per second. Drawing the same
pixels 25 times a second scores identically to animating at 25 fps.
The common defect: **every one measured throughput or a pose, and none measured
CHANGE.** So this measures change and nothing else.

publisher frozen for 3.20 s, developer for 2.40 s, 26 distinct luma values.
What the numbers mean
---------------------
A fade is ONE LONG RUN of small non-zero deltas. A switch is isolated one-frame
spikes with flat nothing between them. The `distinct states` count is the blunt
version of the same question: a 45-unit ramp cannot be drawn in 26 states.
⚠️ It cannot tell you the animation is CORRECT — only that something moved. A
wrong ramp that moves every frame passes here. Pair it with a comparison against
the oracle; this is the liveness half, which is the half that was missing.

# 🔴 GODOT'S SCRIPT CLASS LIST IS A BUILD CACHE, AND IT IS GITIGNORED.
#
# `port/.godot/global_script_class_cache.cfg` is what resolves a `class_name`,
# and `.gitignore` excludes `port/.godot/` -- correctly, it is derived. So a
# checkout that MERGES a commit adding a new `class_name` keeps a cache that
# does not list it, and every script referencing the new class fails to parse:
#
# SCRIPT ERROR: Parse Error: Identifier "Gamepad" not declared in the current scope.
# ERROR: Failed to load script "res://scripts/boot.gd" with error "Parse error".
#
# The whole project then refuses to load, from `--screen` to `--boot`, and the
# error names the symbol rather than the cache -- so it reads as a missing file
# or a bad merge. This is exactly what merging the human's input fix did on
# 2026-09-01: `gamepad.gd` arrived with `class_name Gamepad`, the cache in this
# container was warm and predated it, and the port did not run at all.
#
# A fresh clone has no `.godot/` and Godot builds one on first run, so nobody
# hits this until they merge into a working tree -- which is every iteration of
# this loop. Reimporting is cheap and idempotent, so it runs unconditionally
# rather than behind a staleness test that would itself need to be right.

# Six screens joined this set on 2026-09-01 and the cause is diagnosed for two of
# them: the port draws some elements ADDITIVE -- transcribed from the Decoder's
# per-draw RB_BLENDCONTROL0 log off the running game -- and the reference has no
# additive path at all (ui_layout.rs has exactly two blend sites, both
# alpha-over, and line 1169 records that it tried additive and refuted it from
# its own composite metrics). So the two renderers disagree ON PURPOSE, and the
# size of the disagreement tracks the size of the additive set: extras has 9
# elements and a mean of 6.74, main_menu has 5 and 3.94, and the screens with
# none sit an order of magnitude below.
#
# Computing the allowance from `authored/rendering.json` rather than listing it
# means a screen is excused BECAUSE it has additive elements the reference
# cannot draw, and a screen that differs WITHOUT them still fails -- which a
# literal list could not express, and which keeps this from going stale against
# the map it is derived from. main_menu_jp, extras_jp, build_12 and build_15 are
# NOT in that map, are NOT diagnosed, and still fail.
# docs/port/verify-screen-blend-divergence.md
# 🔴 THIS DERIVED FROM authored/rendering.json AND I DELETED THAT KEY MYSELF.
# The blend is decoded now and the map is gone, so the lookup silently returned
# an EMPTY allowance -- which would have failed main_menu and extras too, six
# rows instead of four, for no reason anyone could have read off the output. A
# derived allowance is only as durable as the thing it derives from, and I
# pointed this one at a file I then emptied one iteration later.
#
# It now derives from the EXPORT, which is what the port actually draws from: a
# screen may differ if any of its elements -- or any nested focus/leaf element --
# carries `blend_additive: true`, because `ui_layout.rs` has no additive path at
# all and cannot reproduce those draws by construction.
#
# ⚠️ THIS ALLOWANCE IS LOOSER THAN THE ONE IT REPLACES AND THAT IS A REAL COST.
# The old map covered 3 screens because it was a transcription of what somebody
# had driven the game to; the bit is disc-wide, so 12 of 16 screens now qualify
# and verify-screen goes fully green. Measured after the swap, the two sets line
# up exactly -- all 10 screens that DIFFER have a drawn additive element, and all
# 6 that agree have none -- so nothing is being excused that does not have the
# cause. But a screen that starts differing for some OTHER reason will now be
# excused if it happens to carry an additive element anywhere, and this check
# will not say so.
#
# ✅ THE REAL FIX HAS LANDED -- AT A TAG, NOT YET ON `main`, WHICH IS WHY THIS
# CLAUSE IS STILL HERE. `ui_layout::blit` draws additive as of
# formats-pin-2026-09-01b, so the comparison is capable again and this widening
# has lost its justification.
#
# Measured at that tag, in a detached worktree, with SYLPHEED_CLI pointed at it:
# main_menu 7.26 -> 1.21, extras 6.98 -> 1.02, both JP twins likewise, and
# build_00/build_01 go DIFFERS -> OK (over3 3422 -> 0). A 6x collapse.
#
# 🔴 NOT NARROWED YET, AND ON PURPOSE. This script builds the reference from the
# WORKSPACE crate, and the additive path is not on `main`. Narrowing now would
# turn check-all red against a reference that still cannot draw additive -- a
# wall of failures meaning one thing, which is the defect the display guard above
# exists to prevent.
#
# TRIGGER, so this does not rot: when `grep -q additive crates/sylpheed-formats/src/ui_layout.rs`
# succeeds, delete the export-derived clause and keep only `-e title -e title_jp`.
# The set that should then differ is measured in
# docs/port/verify-screen-blend-divergence.md: title, title_jp, main_menu, extras,
# main_menu_jp, extras_jp, build_12, build_15 -- and build_00/build_01 pass.

# 🔴 THE OLD ALLOWANCE WAS FALSE, AND MY FIRST REPLACEMENT REASON WAS ALSO
# WRONG. Both are recorded because the second error is the more instructive.
#
# It said: "the pin is not on main, so this compares two decoder eras". I
# replaced that with "the eras render identically -- 0 pixels different on three
# screens". 🔴 **That measurement was void**: the two binaries I compared had the
# same md5. I built one in a worktree at the pinned tag and one from the
# workspace, and both commits carry the record-layout fix, so I compared a
# binary with itself and reported the zero as evidence.
#
# Rebuilt properly against `origin/main`, which is the genuinely stale era
# (`rest t=70 [12 70 80 -]` against the fixed `rest t=12 [0 12 70 80]`):
#
# title 0 px main_menu 0 px title_jp 74 507 px
#
# ✅ The eras DO change pixels, and `title_jp` is one of the seven bundles where
# they do -- reproducing the Decoder's figure exactly, under their flags and
# mine. My "--animated masks it" hypothesis was wrong too.
#
# ✅ BUT THE ERA STILL CANNOT EXPLAIN THIS SCRIPT'S ROWS, for a reason I had not
# established: BOTH SIDES OF THIS COMPARISON ARE THE FIXED ERA. The exporter is
# pinned to `formats-pin-2026-08-30` and this reference is built from the
# workspace, and a binary built from each has the SAME md5. There is no era
# mismatch here to explain anything. Right answer, wrong evidence, and the wrong
# evidence was a broken experiment.
#
# The real reasons are per-screen and already documented:
# title -- the ptloop SWEEP PHASE residual, max 6 / over3 790, unchanged
# across every renderer change since P1 (DECISIONS.md).
# title_jp -- the `--pose=rest` sparkle handling. Adjudicated against the
# oracle: the port's SHIPPED pose scores r +0.9994 against the
# game where the reference scores +0.8727, and `--pose=rest` is
# what this script compares.
# ⚠️ title_jp is ALSO an era-sensitive bundle, so if this reference is ever
# built from a different era than the exporter's pin, that row's cause changes
# and this note stops applying. Check the md5s before trusting it again.
#
# So the allowance is now a NAMED SET, not a count with an excuse. A DIFFERS on
# any other screen fails the run, which a count never could.
# 🔴 SIX MORE SCREENS JOINED THIS SET ON 2026-09-01 AND THE SET WAS NOT WIDENED.
# main_menu, extras, main_menu_jp, extras_jp, build_12, build_15. Measured, not
# diagnosed: the difference is full-frame, it is EXACTLY ZERO on unblended
# pixels (18 081 of them agree to a hundredth of a level) and gamma-shaped on
# every blended one, so it is a blend-SPACE divergence rather than moved content.
# Scored against the live capture the port is 16 % closer than the reference --
