Static code, disc census and runtime all agree; see docs/re/menu-audio-cues.md and docs/re/structures/bgm-two-stems.md. The name carries its `.slb` extension because that is what `sound.pak` hashes -- `BGM_103` alone resolves to nothing, which is how the first draft of this file failed. ✅ AUDITED 2026-08-31 -- the THREE legs are three, and that is now measured rather than asserted. Prompted by the Decoder's point that a decorative second support is worse than none, since a conclusion with two supports reads as better evidenced than one and apparent redundancy is itself the misinformation. Read literally, 'disc census' and 'runtime' could be ONE comparison -- declared wave sizes matched byte-for-byte against the probe -- which would make three legs two. It is a real third leg only if the census EXCLUDES alternatives: if another bank carried the same two sizes, the byte match would not distinguish BGM_103. Measured with this port's own reader (`crates/sylpheed-export/examples/bgm_size_census.rs`): of 32 readable BGM_* banks on the disc, EXACTLY ONE carries waves of that size. The census therefore excludes, the static-code leg names the cue independently, and the three legs stand. ✅ AND THE EXCLUSION IS TIGHTER THAN I STATED. The Decoder attempted to refute it from their own census tool rather than this port's reader: of 32 census rows, exactly one bank carries EITHER of those wave sizes -- not merely both together, which is what I measured. A collision would therefore need to reproduce a single size, not a pair, and none does.",

"loop_why": "MEASURED, and this field's own history is why it says so first. The bed loops; the loop is a RUNTIME field -- `loop_start`/`loop_end` in the XMA decoder context, set by `XMASetLoopData` and logged by Xenia -- and the cycle was watched directly: three wraps, both contexts wrapping at the same instant every time, mean 61.81 s against the 61.93 s authored in `loop_end_s`, 0.2 % apart from instruments sharing nothing. The export is TRIMMED to that window, because Godot loops a whole file and a loop region therefore has to BE the file. ⚠️ The window's START is not measured and is authored as 0, which is known to be wrong -- see `loop_start_why`. 🔴 EVERY SENTENCE THAT PRECEDED THIS ONE WAS REFUTED, and the previous text survived in the manifest for two days after the corrections were written. It said the loop would be `AUDIBLY WRONG AT THE SEAM [refuted]`, that `no loop-point field has been identified [refuted] anywhere`, and that trimming `would INVENT a loop point`. All three are false: the field exists, the 3.4 s of near-silence was the PORT'S loop and not the game's, and the trim is now what the measurement says. The corrections went into `loop_end_why` and `loop_start_why`; this field is the one the exporter concatenates into `manifest.json`, so the export went on telling readers the refuted story. A correction that does not reach the artifact a consumer reads has not been made. 📌 CITATIONS ADDED 2026-09-01, and their absence was found by `audit-kinds` the moment this field got a `kind` -- it had 1 400 characters of prose and nothing openable, which is exactly the state the audit exists to catch and could not see while the field was unlabelled.

Concatenating them plays the piece twice, the second time as a bass-less stem; that was the previous reading and it is refuted. Emitting two files would be wrong for a second reason: MODDING rule 1 is one logical asset, one file, and handing a modder two stems to line up by hand is the reassembly the exporter exists to have already done. WHAT IS SUMMED IS SETTLED; WHAT WAVE 1 IS, IS NOT -- HANDOFF calls it quieter, far more L/R-decorrelated and almost bass-free, so it reads as a surround-rear pair OR a second intensity layer, and `ChannelMask` is 0x0002 on both so the file will not say.

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. The oracle defines \"title settled\" operationally, as its glyph counter first reading the no-plate value 154. This export offers TWO anchors 42 units apart: t=118 (the effect quads) and t=160 (`ptcopyright` at full alpha -- the LAST element to finish building in, and the only one made of glyphs). This line picked 118, while `ScreenView.settle_time()` returns 160 and the boot prints `settles at t=160`, so one binary holds both. Asked in BLOCKED.md H3; not guessed here. \ud83d\udccc SOURCE: the pulse period and its phase behaviour are in docs/re/structures/plate-pulse-measured.md and docs/re/structures/plate-pulse-phase-lock.md, with the raw series in docs/re/data/plate-pulse-timeseries.txt. \u2705 AUDITED 2026-09-01: the corpus's 28.5 fps is a genuinely independent leg -- a different quantity (idle-title presentation rate), measured BEFORE these runs, so it could have come out disagreeing.

It read \"`ptlogo1` has rest.t=251 and stops MOVING at t=42\". In the CURRENT export `ptlogo1.rest.t` is 42 -- equal to when it stops moving. The record-layout fix repaired precisely that element, and the entry was never re-derived under it (REFUTED.md now carries this at \ud83d\udfe1 \u27e8our-reader\u27e9). rest.t is still wrong for transients -- `ptlogo_back2eff1` is a two-frame flash whose rest.t=54 is the flash PEAK -- and for `pteff00`, whose rest.t=16 sits at the end of the fade-FROM-black while a fade-TO-black runs 261..269. Re-derived 2026-09-01: docs/port/plate-arrival-halves.md. \ud83d\udd34 AND IT IS NOT THIS DEFECT'S CAUSE. The plate's ARRIVAL is a declared keyframe (transparent to t=214, opaque at t=236), not a rest pose; rest.t=236 only chooses where `holding` parks it, and 236 is that ramp's own peak.

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.",

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."

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.",

//! Run the Decoder's own falsifier for "a nested record's `+0x08` is its loop
|
||||
//! length" against the bundles THIS PORT SHIPS, before shipping 120 for 105.
|
||||
//!
|
||||
//! HANDOFF (`27938aa`, delivered at `07e93ce`) says the plate's glow cycles over
|
||||
//! **120** units while its keyframes end at 105, and instructs the port to stop
|
||||
//! shipping 105. The port's `ScreenView` derives a looping record's period from
|
||||
//! the element's largest keyframe time, so it does ship 105 — and the field that
|
||||
//! would fix it is decoded in an *example* and a *test* on the Decoder's branch
|
||||
//! and **exposed in `sylpheed_formats`' public API on no ref at all**.
|
||||
//!
|
||||
//! ✅ **Since then the crate exposes it** — `ui_layout::loop_length_units`, taken
|
||||
//! at `formats-pin-2026-08-30b` — and `screen.rs` has deleted its local copy.
|
||||
//!
|
||||
//! 🔴 **This file deliberately did NOT follow it.** The read below is still the
|
||||
//! raw four bytes, because the moment a control calls the API it is meant to
|
||||
//! check, it stops being a control and becomes the API tested against itself. It
|
||||
//! is the independent reading that makes the falsifier mean anything.
|
||||
//!
|
||||
//! So this re-runs both of their controls:
|
||||
//!
|
||||
//! * **the falsifier** — `+0x08 < max keyframe time` must never occur; an
|
||||
//! animation cannot restart before its own last pose;
|
||||
//! * **non-triviality** — if every record had `+0x08 == max t` the field would
|
||||
//! carry nothing and the name would be a relabelling of the keyframes.
|
||||
//!
|
||||
//! and adds the one they could not run: the same two, restricted to the records
|
||||
//! **this port actually animates**. A disc-wide 0.00 % violation rate says
|
||||
//! nothing about my six screens if all six sit in the exceptional tail.

# Your mods go here
|
||||
|
||||
A mod **replaces a file by shadowing its path**. There is no manifest, no
|
||||
registration and no load order: if a file exists here at the same relative path
|
||||
it has in the export tree, the game reads yours instead.
|
||||
|
||||
```
|
||||
export/sprites/title/main_menu/ptbtn01.png <- what the exporter wrote
|
||||
data/mods/sprites/title/main_menu/ptbtn01.png <- what the game will use
|
||||
```
|
||||
|
||||
That works for **every** asset kind the port reads — a screen's JSON, a sprite
|
||||
PNG, a sound cue, the music bed, a movie — because every read goes through one
|
||||
resolver (`port/scripts/export_tree.gd`, `ExportTree.resolve`).
|
||||
|
||||
Nothing under `export/` is ever touched, so **re-exporting from your disc is
|
||||
always safe**, and *"did I break it?"* is answered by moving your file out of
|
||||
this directory.
|
||||
|
||||
Point the game somewhere else with `SYLPHEED_MODS=/path/to/tree`.
|
||||
|
||||
## The game tells you what you changed
|
||||
|
||||
Every file a mod replaces is printed the first time it is read:
|
||||
|
||||
```
|
||||
mod: sprites/title/main_menu/ptbtn01.png <- /work/data/mods/sprites/title/main_menu/ptbtn01.png
|
||||
```
|
||||
|
||||
A modded run that looked identical to an unmodded one in the log would leave you
|
||||
with exactly one debugging tool — delete the mod and try again.
|
||||
|
||||
## Try it in ten seconds
|
||||
|
||||
Replace the `NEW GAME` label with a magenta block. The size is the original's,
|
||||
`203x43`, and nothing here is derived from the disc:
|
||||
|
||||
```bash
|
||||
mkdir -p data/mods/sprites/title/main_menu
|
||||
ffmpeg -f lavfi -i "color=c=0xff00c8:s=203x43" -frames:v 1 -pix_fmt rgba \
|
||||
data/mods/sprites/title/main_menu/ptbtn01.png
|
||||
godot --path port -- --menu
|
||||
```
|
||||
|
||||
Delete the file to put it back.
|
||||
|
||||
## Nothing in here is committed
|
||||
|
||||
`.gitignore` excludes everything in this directory except this README. That is
|
||||
deliberate: a mod is usually an *edited game asset*, and this repository never
|
||||
holds game assets — not in `export/`, and not here either.
|
||||
|
||||
## One tree, not a stack
|
||||
|
||||
Several mods layering over each other would need a load order, and a load order
|
||||
needs a rule nobody has asked for yet. Today there is one override tree. If you
|
||||
want more, say so rather than assuming the port has an answer.

# Agreed retro — Port and Decoder, 2026-08-31
|
||||
|
||||
Two self-reviews, one round of mutual attack, and the result both agents accept.
|
||||
|
||||
* Decoder's own review: `docs/agents/RETRO-2026-08-31.md` on `auto/frame-blend-draw-path`.
|
||||
* Port's failures and the original eight proposals: this file's §1, and `docs/port/DECISIONS.md`.
|
||||
|
||||
⚠️ **Nothing here is applied to `PROTOCOL.md`.** The parts that change the shared
|
||||
refuted-claim register are presented for the human, not enacted by two agents
|
||||
agreeing with each other. Both agents remain paused.
|
||||
|
||||
## 1. The single most expensive thing we did
|
||||
|
||||
**We let claims that rest on our own renderer sit in the register as settled
|
||||
refutations.**
|
||||
|
||||
`REFUTED.md` killed *"`T8aD +0x04` bit `0x02` selects an additive blend"* with the
|
||||
reason *"blending those sprites additively worsens every measure against the
|
||||
capture"* — a statement about our renderer, made while that renderer had a stale
|
||||
keyframe association, no leaf geometry and no rotation. The field is real. It sat
|
||||
dead for weeks, and the cost was: a published *"the blend is not on the disc"*, an
|
||||
authored table built on it, **three rounds of per-element transcription**, and one
|
||||
agent steering a search deliberately around the entry.
|
||||
|
||||
The Port paid the mirror of it: a phase sweep that *"refuted"* menu-looping was
|
||||
measuring the Port's own sweeps, not the game's, and was re-run and reported as
|
||||
*strengthened* one iteration before the oracle contradicted it.
|
||||
|
||||
📌 **Neither of us was careless. The rule was in `PROTOCOL.md` the whole time** —
|
||||
*"anything derived from our own renderer rather than a capture"* is named as a
|
||||
prime refutation target. What was missing is that nothing **re-opens** a claim when
|
||||
the instrument that killed it improves.
|
||||
|
||||
## 2. The gap underneath our controls
|
||||
|
||||
`PROTOCOL.md` already requires running an instrument through a control. **We both
|
||||
did, and it did not help**, because:
|
||||
|
||||
> **Our controls verified capability, not configuration.**
|
||||
|
||||
* The Port's additive material passed every control — they tested whether the
|
||||
*method* detects a blend difference, not whether *this run* had `blend_mode` set.
|
||||
It was left at Godot's default, `MIX`. The change predicted a large move and
|
||||
delivered **0.03**, and would have been publishable as a careful negative.
|
||||
* The Decoder's vertex dump passed every control — they tested whether NDC→pixel
|
||||
conversion is right, not whether the dump captured all six quads. It captured
|
||||
**two**, with a well-formed line and no ellipsis, and four elements therefore
|
||||
appeared *in no draw on any screen*.
|
||||
|
||||
## 3. The gap neither of us had noticed
|
||||
|
||||
> **We have never given a NEGATIVE a positive control.**
|
||||
|
||||
Every *"undecodable, with reach"* page lists **where we looked**. Not one shows
|
||||
that the search method **can find a property that is there**. *"Absent"* and
|
||||
*"my search does not work"* are indistinguishable in all of them — and *"the blend
|
||||
is not on the disc"* is exactly that failure, published.
|
||||
|
||||
## 4. The rules we agree to work by
|
||||
|
||||
| | rule | replaces / from |
|
||||
|---|---|---|
|
||||
| **R1** | **A refutation whose instrument is one of our renderers is not a refutation.** It is *"our renderer disagrees"* — 🟡, not ❌. Each register entry names its `instrument:`, and a `--stale <instrument>` mode lists everything that instrument killed, for re-opening when it changes. | Port P2, strengthened by Decoder |
|
||||
| **R2** | **State the expected number before you read the actual one** — the effect size for a change, the *count* for a parse. *"This draw declares 24 indices, so I expect 6 quads."* | Port P3+P4, merged by Decoder |
|
||||
| **R3** | **Instruments print their own completeness**: *n* resolved of *n* declared, and refuse to be trusted otherwise. | Port P4 |
|
||||
| **R4** | **A negative carries a positive control.** Before publishing *"no field encodes X"*, show the same search finding a field known to exist. | Decoder D1 — **neither agent had this** |
|
||||
| **R5** | **Label provenance is part of the artefact.** A field hunt states where its ground truth came from, and **renderer-derived labels are disqualified for disc-side questions.** | replaces Port P1, which had no teeth — the question *was* asked and answered wrongly |
|
||||
| **R6** | **Suppression localises disagreement; only the oracle labels it.** It is two renders of ours: it found the frames, it could not have said *additive*. | Decoder's correction of Port P5 |
|
||||
| **R7** | **Coverage is computed against a declared denominator** — *"35 of the 41 elements entry 6 declares"*, never *"everything is covered"*. | Port P6 + Decoder |
|
||||
| **R8** | **Hold the role line even when the answer looks obvious.** The asymmetry is the argument: refusing to infer `ptframe4` cost one message; inferring *"frame-shaped and mostly transparent ⇒ additive"* would have cost a wrong renderer until the title was captured — **and the title capture killed that exact rule.** | Port P7, agreed |
|
||||
| **R9** | **The message carries the delta and names the file and section; it does not summarise it.** Short messages are safe only when the pointer is precise. | Port P8 + Decoder's caveat |
|
||||
| **R10** | **A disagreement is evidence about the CHAIN — disc → decode → render → capture — not about a link.** A chain-level residual gets a named owner and a next experiment, or is recorded as unowned. | Decoder F |
|
||||
| **R11** | **A cross-agent pointer must fail loudly when it goes stale.** Every staleness incident here was silent. | Port, new |
|
||||
| **R12** | **Each iteration names the gate it moved, or says plainly that it moved none.** | Port, new — see §5 |
|
||||
|
||||
## 5. The efficiency finding neither review led with
|
||||
|
||||
**The record has grown faster than the artifact.** `DECISIONS.md` is past 13 000
|
||||
lines. This session produced twelve Port commits of genuine measurement — and the
|
||||
milestone gate did not move, because **P5's gate has needed a human, not code, the
|
||||
whole time.** Writing more is not free, and a capability that lives only in the
|
||||
record is, to the person who needs it, absent.
|
||||
|
||||
R12 exists so that a run of iterations that moves no gate **says so**, rather than
|
||||
reading as progress because each entry is individually rigorous.
|
||||
|
||||
## 6. What each agent changes, without a human
|
||||
|
||||
* **Decoder:** a standing pointer at the top of `HANDOFF.md` — which their brief
|
||||
already forces them to read every iteration, and which is theirs to write — to
|
||||
`git show origin/auto/port-p6-audio:docs/port/BLOCKED.md`. **One line in a file
|
||||
they own**, routing the Port's standing asks into a file they must already open.
|
||||
This closes a gap `BLOCKED.md` records as having cost three sessions.
|
||||
* **Port:** `instrument:` provenance and `--stale` in `check-claims`; completeness
|
||||
lines (R3) and predicted counts (R2) in the port's tools; a loud staleness
|
||||
failure for peer pointers (R11).
|
||||
|
||||
## 7. What needs the human
|
||||
|
||||
1. ✅ **The register re-classification (R1) — DONE 2026-09-01, by the human**, on
|
||||
`docs/re/REFUTED.md` at the Decoder's tip. All **222** entries now carry an
|
||||
`⟨instrument⟩`; the file opens with a reading guide naming which instruments
|
||||
are ours; R1 is now standing text in `PROTOCOL.md`; and
|
||||
`tools/stale-instrument` is the `--stale` query — run it whenever you improve
|
||||
a renderer, a reader or the harness, and it lists what that instrument killed.
|
||||
|
||||
**Ten entries moved ❌ → 🟡**, each naming what would settle it: eight
|
||||
`render-vs-capture`, one `our-reader`, one `harness`.
|
||||
|
||||
Three things the pass turned up that neither self-review had:
|
||||
|
||||
* **The `rest()` question is open, and had been reading as settled in both
|
||||
directions.** *"rest = last keyframe"* was refuted by the sibling argument;
|
||||
that refutation was then refuted by correlating our render against
|
||||
captures. Both legs run through our renderer, so under R1 neither survives
|
||||
— and which one you believed depended on which entry you found first.
|
||||
🔴 **This one is load-bearing for the port**: `rest()` decides the pose
|
||||
every plateau-less element is drawn at.
|
||||
* **A withdrawal never reached its sibling.** *"2 391 frames, max glyph 0"*
|
||||
was withdrawn because a long-lived `x11grab` stream degrades and then
|
||||
repeats a stale frame. The 1 674-sample negative three lines above it —
|
||||
same probe, same instrument, comparable duration — was left standing as a
|
||||
*reinstated measurement*. §1's lesson, inside the register itself.
|
||||
* **83 of 222 entries — 37 % — record no instrument at all.** Not disputed,
|
||||
not safe: **unauditable**. `stale-instrument unrecorded` is the backfill
|
||||
queue, and it is larger than every other group combined.
|
||||
|
||||
2. **P5's gate** — a person clicking through the port. Unchanged, and it is the

## 5. A multichannel capture must pass a provenance check BEFORE it is analysed
|
||||
|
||||
`tools/port/check-capture FILE.wav` — run it first, every time.
|
||||
|
||||
⚠️ **This section exists because a capture of the game's own 6-channel output was
|
||||
analysed at length and the file was corrupt.** It got three controls, a
|
||||
drift test and a written-up negative, and every one of those was sound; none of
|
||||
them could see that channels were missing, because the corruption was upstream of
|
||||
everything they tested.
|
||||
|
||||
**PulseAudio was remapping between two mismatched channel maps, and a 6-channel
|
||||
remap silently drops and duplicates.** The Decoder proved it with a control that
|
||||
needs no emulator and no disc — six channels each carrying a different tone,
|
||||
through the same sink and the same `parec` invocation
|
||||
(`docs/re/audio-capture-channel-map-trap.md`):
|
||||
|
||||
| ch | played | recorded |
|
||||
|---|---|---|
|
||||
| 0 | 400 | 400 |
|
||||
| 1 | 800 | **3200** |
|
||||
| 2 | 200 | 200 |
|
||||
| 3 | 1600 | **800** |
|
||||
| 4 | 3200 | **800** |
|
||||
| 5 | 6400 | **200** |
|
||||
|
||||
**Two source channels were gone entirely** and two were duplicates. Setting the
|
||||
sink's `channel_map` to the guest's own (`FL,FR,FC,LFE,RL,RR`) and passing the
|
||||
same map to `parec` returns all six.
|
||||
|
||||
### The signature is an exact duplicate pair, and only a hash finds it
|
||||
|
||||
Duration is right. Channel count is right. `Corked: no`. There is no error
|
||||
anywhere, and the **per-channel levels look entirely reasonable** — which is the
|
||||
whole difficulty. In the tool's own known-bad control, all six channels report a
|
||||
peak of **−18.063656 dB, identical to six decimals, while containing three
|
||||
duplicate pairs.** A level check cannot see this. Hashing each channel can.
|
||||
|
||||
Two channels of a real surround mix are never byte-identical over tens of
|
||||
seconds. On the corrupt game capture the tool reports:
|
||||
|
||||
```
|
||||
ch2 peak -4.466272 ba497de78217c438a3e430c5ef6b951b
|
||||
ch5 peak -4.466272 ba497de78217c438a3e430c5ef6b951b
|
||||
🔴 ch2 and ch5 are BYTE-IDENTICAL
|
||||
```
|
||||
|
||||
⚠️ **It is a necessary check, not a sufficient one.** Passing says the file has no
|
||||
duplicated channels. It says nothing about whether the right thing was recorded —
|
||||
that is what §1's correlation against a known source is for, and a capture should
|
||||
survive **both** before anything is concluded from it.
|
||||
|
||||
### Two more conditions, learned the same way
|
||||
|
||||
* **Start the recorder before the process you are capturing**, so `t = 0`
|
||||
precedes it and the window certainly contains the moment of interest.
|
||||
* **Log what was on screen, with timestamps keyed to the recording's own clock.**
|
||||
A capture that matches nothing is then diagnosable rather than ambiguous; the
|
||||
corrupt one could not be told apart from "recorded the wrong phase of the boot"
|
||||
by any amount of analysis at this end.
|
||||
|
||||
And the failure this page already warns about, in a second costume:
|
||||
`run-canary` is silent **twice over** — `SDL_AUDIODRIVER=dummy` *and*
|
||||
`--mute=true`. Fix only the first and Canary attaches a healthy 6-channel stream
|
||||
at 100 % volume, reports `Corked: no`, and emits a 19 MB WAV of zeroes.
|
||||
|
||||
## 7. A capture can be starved — right duration, holes punched through it
|
||||
|
||||
`check-capture` tests this too, and it is the second way a recording looks
|
||||
perfect and carries nothing.
|
||||
|
||||
**A monitor sink advances at wall-clock rate and substitutes silence whenever the
|
||||
producer is late.** An emulator running below real time therefore yields a file
|
||||
of exactly the right duration, the right channel count, no duplicated channels —
|
||||
chopped into fragments with holes between them, thousands of times over.
|
||||
|
||||
Measured independently on the capture that prompted this (the Decoder's numbers
|
||||
on the untruncated original in brackets):
|
||||
|
||||
| | |
|
||||
|---|---|
|
||||
| frames silent on **all six** channels | **35.6 %** [39.3 %] |
|
||||
| alternating runs | **10 482** [10 595] |
|
||||
| median burst / gap | **13.5 ms / 3.9 ms** [13.6 / 3.9] |
|
||||
| period | **17.4 ms → 57 Hz** [≈17.5 ms → 57 Hz] |
|
||||
|
||||
⚠️ **This destroys envelope correlation by construction.** What dominates the
|
||||
envelope of such a file is the dropout schedule, not the content — so §6's method
|
||||
was working correctly on a file that could not carry the signal, and the negative
|
||||
it produced said nothing about the game.
|
||||
|
||||
### Two thresholds I invented were wrong, and the controls caught both
|
||||
|
||||
1. **Counting exact-zero frames.** Real audio crosses zero constantly, so a clean
|
||||
voice track scored **5 947 "gaps" of median 0.0 ms** and was called starved. A
|
||||
gap is a **run**, not a sample: only runs of ≥ 1 ms count.
|
||||
2. **Gap count and median length.** A genuine music-and-effects bed has **454
|
||||
gaps at a median of 1.4 ms** — quiet 16-bit passages really are zero for
|
||||
milliseconds — so neither statistic separates it from a starved file.
|
||||
|
||||
3. 🔴 **The gap RATE alone.** This one shipped, and the Decoder found it: raising
|
||||
the client buffer keeps cutting the rate while total silence **bottoms out and
|
||||
then doubles**, because an over-large buffer starves in a few enormous holes
|
||||
instead of many small ones. Its `PULSE_LATENCY_MSEC=500` capture scores
|
||||
**1.3 gaps/s — better than a genuine music bed at 3.3 — while being 50 %
|
||||
silence**, and a 20/s bar passed it.
|
||||
|
||||
**It takes two numbers, because either one alone is blind to the failure next
|
||||
door** — the same shape as a level table that cannot see a duplicated channel.
|
||||
Reproduced on a file held here (`bigholes`: a real bed with 350 ms holes punched
|
||||
into it) so the regime is controlled rather than quoted:
|
||||
|
||||
| control | all-channel silence | gaps/s | verdict |
|
||||
|---|---|---|---|
|
||||
| real music+SFX bed | 1.1 % | 3.3 | **PASS** |
|
||||
| voice track, mono, real pauses | 53.2 % | 0.3 | **PASS** |
|
||||
| bed with 350 ms holes | **46.3 %** | 3.2 | **FAIL** |
|
||||
| the starved capture | **35.6 %** | 30.9 | **FAIL** |
|
||||
|
||||
Rate alone cannot separate rows 2 and 3; silence alone cannot separate rows 1 and
|
||||
3. **The pair does:** fail when ≥ 10 % of the file is silent on every channel
|
||||
*and* there is at least 1 gap per second. Real audio is either mostly not silent,
|
||||
or silent in a few long stretches — not both at once.
|
||||
|
||||
### A format it cannot read is refused, not guessed at
|
||||
|
||||
Everything in the starvation check assumes 16-bit signed. An ALSA `type file` tee
|
||||
writes **float32** (`SND_PCM_FORMAT_FLOAT_LE`), and read as s16 that produces a
|
||||
*plausible-looking* file — the Decoder measured one, and its only tell was
|
||||
per-channel peaks alternating **exactly**, which is the two halves of each float
|
||||
landing in alternate channels.
|
||||
|
||||
So an unreadable format ends the run at **`PARTIAL`** (exit 2), not `PASS`:
|
||||
channels were checked, starvation was not, and the tool says which. A checker
|
||||
that claims a check it skipped is the shape of every failure this file documents.
|
||||
|
||||
⚠️ **`WAVE_FORMAT_EXTENSIBLE` (tag `0xFFFE`) is accepted at 16 bits**, and the
|
||||
first version of the guard was not — it rejected one of this tool's own controls,
|
||||
a file `ffprobe` correctly calls `pcm_s16le`. **A format guard that refuses a
|
||||
legitimate capture is the same defect as one that mis-reads an illegitimate one**,
|
||||
pointing the other way. The check turns on `wBitsPerSample`, which is what
|
||||
actually decides the sample layout; a float tee is 32-bit and is still caught.
|
||||
|
||||
### The control sweep, which is the tool's real specification
|
||||
|
||||
**Run it: `tools/port/check-capture-controls`.** 🔴 Until 2026-08-30 this table was prose — the specification existed and nothing executed it, so a regression in `check-capture` or a drifting threshold would have gone unremarked in a tool whose own history is *two invented thresholds that were both wrong and were caught only by controls*. This document states the principle it was breaking: **"a control that does not execute is not a control."**
|
||||
|
||||
⚠️ The verdicts below are **compressed**. `check-capture` emits two — one for channel provenance, one for starvation — and the sweep asserts the pair, because the voice control is `PASS` on channels and `UNJUDGED` on starvation *by design* and a single word cannot say that. A starved file **short-circuits** before the channel check, which the sweep records as `n/a` rather than as a failure: *the check did not run* and *the check failed* are different facts.
|
||||
|
||||
⚠️ The **starved capture cannot be rebuilt** — that artifact was transient and is gone. The sweep reports it `MISSING` rather than omitting it, and deliberately does not synthesise one from the statistics published above: a control fitted to the answer it must give is not a control either.
|
||||
|
||||
| file | verdict |
|
||||
|---|---|
|
||||
| real music+SFX bed | `PASS` |
|
||||
| voice track, mono, 53 % real pauses | `PASS` |
|
||||
| six distinct tones (PCM and extensible) | `PASS` |
|
||||
| bed with 350 ms holes punched in | **`FAIL`** |
|
||||
| the starved capture | **`FAIL`** |
|
||||
| the same tones as float32 | **`PARTIAL`** |
|
||||
|
||||
### ⚠️ The regime this tool cannot judge, and says so
|
||||
|
||||
**High silence with very few gaps is what a real voice track looks like (53.2 %
|
||||
in 0.3 gaps/s) and also what an over-buffered capture looks like.** No statistic
|
||||
here separates them. The tool prints `UNJUDGED` and tells you to check the file
|
||||
against a known source rather than passing it silently — because inventing a bar
|
||||
for a regime with no control in it is how the two bars above came to be wrong.
|
||||
|
||||
⚠️ **A control that does not execute is not a control.** An earlier version
|
||||
returned immediately for a single-channel file, so the mono voice track — one of
|
||||
the four controls — was never actually run through the check it was meant to
|
||||
control. Mono now skips only the duplicate test.
|
||||
|
||||
### 🟡 The monitor-sink route may be fixable after all — retry before rebuilding
|
||||
|
||||
An earlier version of this section said the route *"cannot be fixed by
|
||||
configuration"*. **Withdrawn.** That inferred from the holes that the guest runs
|
||||
below real time, without testing the alternative: **the client buffer is simply
|
||||
tiny.** Xenia asks SDL for 256 samples — **5.33 ms** at 6 ch — against a stock
|
||||
`daemon.conf` with no fragment tuning.
|
||||
|
||||
| client buffer | silence | gaps/s |
|
||||
|---|---|---|
|
||||
| Xenia default (~5.3 ms) | 39.3 % | 30.5 |
|
||||
| `PULSE_LATENCY_MSEC=200` | **15.6 %** | 3.5 |
|
||||
| `PULSE_LATENCY_MSEC=500` | 50.1 % | 1.3 |
|
||||
|
||||
⚠️ Not clean, and not like-for-like — 88 s against 347 s, and the short run covers
|
||||
the splash logos where silence is real. But **the capture route deserves a retry
|
||||
at ~200 ms before anyone spends a session on a Canary rebuild.**
|
||||
|
||||
### The tap, if configuration is not enough
|
||||
|
||||
`parec` reads a monitor that advances at wall-clock rate and substitutes silence,
|
||||
so **every moment the emulator runs below real time is a hole**, and the timebase
|
||||
is warped non-uniformly — deleting the silences compresses time unevenly rather
|
||||
than repairing it. The route that would work is an **internal tap at
|
||||
`SDLAudioDriver::SubmitFrame`**, which sees every frame the guest produces in
|
||||
guest order with no wall clock in the loop.
|
||||
|
||||
⚠️ That needs a Canary rebuild, and the Decoder has costed it: `build-canary`
|
||||
targets a source root that does not exist in that container, the warm build tree
|
||||
is configured against the same missing path, so any change is a full reconfigure
|
||||
plus a full compile on a box with ~700 MB free and a history of parallel builds
|
||||
OOM-killing the host. **A whole session for one probe** — the human's call, not
|
||||
an agent's.
|
||||
|
||||
### And a header that never got patched
|
||||
|
||||
A streaming writer leaves `data` declaring **0 bytes**. `check-capture` says so
|
||||
and tells you the duration is unverified — which is not pedantry: the file shared
|
||||
here was **copied while it was still being written**, and the provenance claim
|
||||
that came with it was wrong about both its length and what it contained.
|
||||
|
||||
## 6. Finding one component inside a mix — and why §1's method cannot
|
||||
|
||||
🔴 **This section begins with a retraction.** Two captures of the game's own
|
||||
output were analysed with sliding envelope cross-correlation and declared not to
|
||||
contain the intro's audio. **The instrument was never controlled for the actual
|
||||
task**, and when it finally was, it failed:
|
||||
|
||||
> Can it find the movie's bed inside a synthetic mix of that bed plus the three
|
||||
> voice streams? **r = 0.415** — below the `r > 0.8` bar those negatives were
|
||||
> judged against.
|
||||
|
||||
The first negative happened to be right (the file was independently proved
|
||||
corrupt by a tone control). **It was right by luck, and the reasoning behind it
|
||||
was not supported.** A filter that fails its own known-positive is dead, not
|
||||
tuneable.
|
||||
|
||||
### What was wrong: the threshold, not the idea
|
||||
|
||||
`r > 0.8` was calibrated on **clean-against-clean** comparisons, where it is
|
||||
correct — a transcode against its source scores 1.000. A *component inside a
|
||||
mix* can never score that, because everything else in the mix is uncorrelated
|
||||
noise from the component's point of view. Judging one task by the other's bar
|
||||
guarantees a false negative.
|
||||
|
||||
**Judge on the LAG and the MARGIN instead.** A real match lands at the *right*
|
||||
lag with a clear gap to the runner-up; a false one is a plateau. And **band-limit
|
||||
first**, so the component you are hunting dominates what you measure.
|
||||
|
||||
### The calibration, on a known-present and a known-absent pair
|
||||
|
||||
Both bands, both directions, envelope at 0.1 s, minimum 60 s overlap:
|
||||
|
||||
| hunting | band | against | *r* | lag | **margin** |
|
||||

**A 20–50× separation in the margin, and the lag is right or absurd.** That is a
|
||||
decision rule set by controls rather than by tuning until the data agreed —
|
||||
which is the distinction that matters, and the one the first version of this
|
||||
method skipped.
|
||||
|
||||
⚠️ **Reach.** The known-positive is a *synthetic* mix at equal gains. A real game
|
||||
mix weights its components differently, so this bounds the method rather than
|
||||
modelling the real case exactly. It is enough to separate present from absent; it
|
||||
is not a level measurement.
|
||||
|
||||
## What none of this establishes
|
||||
|
||||
That it *sounds right*. Every method here shows correspondence to a source, not
|
||||
that the source is the audio the game plays at that moment, and not that levels
|
||||
are sane in a mix. A ten-second human listen still answers something no
|
||||
measurement above does — so when a result rests on one of these, say which one.
|
||||
|
||||
## 4. What the exporter checks, so nobody has to remember to
|
||||
|
||||
`sylpheed-export` measures **peak level and duration** of every audio file it
|
||||
writes and records both in `manifest.json`; `sylpheed-export check` refuses a
|
||||
tree whose peak is ≤ −90 dBFS (silent) or ≥ 0 dBFS (clipping).
|
||||
|
||||
Those are content checks in a format validator on purpose. Silence is the failure
|
||||
this page opens by naming — right duration, right channel count, right size, full
|
||||
of zeroes — and every structural check passes it. Clipping is the other one, and
|
||||
the BGM can produce it, because a music bank is two stems summed at unity gain
|
||||
(HANDOFF Q10).
|
||||
|
||||
⚠️ Neither says the audio is the **right** audio. `docs/port/BLOCKED.md` says
|
||||
which bindings are measured and which are still authored, and no measurement on
|
||||
this page can move a row there.

### `command` and `why`, on every media entry
|
||||
|
||||
`command` is the exact ffmpeg invocation that produced the file. MISSION §6: a
|
||||
modder who dislikes the quality re-runs one line rather than reverse-engineering
|
||||
what was done to their asset. `why` is where the value came from, in the
|
||||
project's three-way vocabulary — **decoded** off the disc, **measured** off the
|
||||
running game, or **chosen**. A `why` that does not say which of those it is has
|
||||
not done its job.
|
||||
|
||||
### `audio`, field by field
|
||||
|
||||
| field | |
|
||||
|---|---|
|
||||
| `kind` | `se`, `bgm` or `voice`. The runtime dispatches on it, so it is a field rather than a prefix on `name` that a consumer would have to parse |
|
||||
| `name` | the **role**, not the disc asset: `move`, `confirm`, `back`, `main_menu`. Which bank plays a role is authored and expected to change; a rename on the disc side must not be a change to the Godot project. ⚠️ **`voice` is the exception and keys by MOVIE NAME** (`ADV`, `S00A`), because there is no role to name: the binding of recording to picture came off the disc's own movie manifest, so unlike a music bed nothing about it was chosen |
|
||||
| `peak_dbfs` | measured off the finished file. **Required.** Silence is the audio failure that looks like success — right duration, right channel count, right size, full of zeroes — and clipping is the other one, which the BGM can produce because it is a sum of two stems at unity gain. `sylpheed-export check` refuses a tree whose peak is ≤ −90 dBFS, and applies a **kind-dependent** upper bound. 🔴 This paragraph used to state a flat *≥ 0 dBFS* and was wrong about the port's own export: `confirm` ships at **+0.18** and the `ADV` voice at **+0.31**, so a consumer implementing a validator from this file would have rejected a valid tree. The rule is: a **`bgm`** is a sum *we* produced, so a peak at or above full scale is our arithmetic and is refused outright; an **`se`** or **`voice`** is a single wave off the disc, mastered near full scale, and a lossy decode of it overshoots by a fraction of a dB — those are allowed to **+1.0 dB**. ⚠️ The +1.0 is a judgement, not a measurement: a few tenths is reconstruction overshoot and a whole dB is not, and if a cue ever trips it the right response is to measure the overshoot distribution, not to loosen the bound |
|
||||
| `duration_s` | measured off the finished file, so that a claim about a cue's length can be checked against the finding that produced it |
|
||||
| `name_match` | the game's own cue identifier **guessed by name**. Absent means nobody claimed one — never that the binding is unknown. The binding is the measured part; the name is not |
|
||||
| `loop_mode` | what the runtime does at the end of the file, where that was authored. Absent on a cue: a cue ends |
|
||||
|
||||
**A `voice` entry is a cutscene's dialogue, and it is a separate file on
|
||||
purpose.** On this disc a movie's `.wmv` carries music and effects only; the
|
||||
voice is a byte region of one continuous XMA stream in `sound.pak`, bound by the
|
||||
movie manifest. A consumer plays the two together, **from the same instant** —
|
||||
there is no offset and none is authored. A movie with no `voice` entry is
|
||||
genuinely unvoiced, which is the honest answer for most `hokyu_*` cutscenes;
|
||||
nothing is substituted, and the manifest carries a warning naming the movie.
|
||||
|
||||
⚠️ The `why` on a `voice` entry names every region chunk the exporter **dropped**
|
||||
and its measured length. That is not commentary: which chunks of a region are the
|
||||
track is an open decoding question (see `docs/port/BLOCKED.md`), and a consumer
|
||||
reading a shorter file than it expected should be able to see what was left out
|
||||
rather than infer it.

# Running the port
|
||||
|
||||
**P5's gate is *"a human clicks through it"*, and until now there was no page
|
||||
telling a human how.** The commands existed — in `boot.gd`'s header comment and
|
||||
scattered through a twelve-thousand-line `DECISIONS.md`. A capability that lives
|
||||
only in the record is, to the person who needs it, absent.
|
||||
|
||||
Everything below has been run. Where a number is quoted it was measured in this
|
||||
container, and where the container distorts it that is said rather than left for
|
||||
the reader to discover.
|
||||
|
||||
## 1. Build the asset tree
|
||||
|
||||
The Godot project reads `export/`, never the disc.
|
||||
|
||||
```bash
|
||||
cargo run --release -p sylpheed-export -- export --disc /disc --out export
|
||||
```
|
||||
|
||||
Roughly four minutes, most of it transcoding two movies. It **rewrites `export/`
|
||||
wholesale** — never hand-edit anything in there; hand-written decisions live in
|
||||
`authored/` beside it, and survive a re-export.
|
||||
|
||||
## 2. The P5 walk, from a cold start
|
||||
|
||||
```bash
|
||||
godot --path port -- --boot --play
|
||||
```
|
||||
|
||||
This is the one a human should judge. It boots the way the game does — two
|
||||
splashes, the `ADV` intro, the title — hands over to the menu on Ⓐ, and then
|
||||
**stays live and waits for input**.
|
||||
|
||||
| you press | what should happen |
|
||||
|---|---|
|
||||
| Ⓐ on the title | the main menu opens on **NEW GAME** |
|
||||
| ⬆ / ⬇ | one item, wrapping at both ends |
|
||||
| ⬅ / ➡ | **nothing** — measured, and implemented as an explicit no-op |
|
||||
| Ⓐ on **EXTRAS** | the EXTRAS submenu, opening on **MISSION SELECT** |
|
||||
| Ⓑ in EXTRAS | back to the main menu, **on the item you left** |
|
||||
| Ⓑ on the main menu | back to the title |
|
||||
| Ⓐ on the title again | the menu, **still on the item you left** |
|
||||
|
||||
That last row is the one worth checking deliberately: the main menu **remembers
|
||||
its cursor**, and every submenu **resets** to its own opening item. Both are
|
||||
measured, and they disagree on purpose.
|
||||
|
||||
⏱ **The intro is ~157 s.** To skip straight to the menu:
|
||||
|
||||
```bash
|
||||
godot --path port -- --menu=main_menu
|
||||
```
|
||||
|
||||
and to drive it unattended:
|
||||
|
||||
```bash
|
||||
godot --path port -- --menu=main_menu --script=down,down,down,down,accept,cancel
|
||||
```
|
||||
|
||||
🔴 **This example used to say `down,down,accept,cancel`, and it walked the wrong
|
||||
path.** Two ⬇ from the opening item lands on **`TUTORIAL`**, whose destination this
|
||||
export does not carry — so the example exercised a *not-carried* message and
|
||||
returned, never opening a submenu at all. **`EXTRAS` is the fifth item**, so it
|
||||
takes four. The one submenu P5's gate rests on was the one the runbook's own
|
||||
command did not reach. Verified 2026-08-31 by running both.
|
||||
|
||||
🔴 `--script` **without** `--play` or `--menu` refuses and says so. It used to
|
||||
parse, be stored, and do nothing.
|
||||
|
||||
## 3. What is knowingly missing — not bugs
|
||||
|
||||
Four of the five main-menu destinations are **measured but not in this export**:
|
||||
they live in other archives (`GP_SAVE_LOAD`, `GP_OPTIONS`, …). Pressing Ⓐ on them
|
||||
prints what it would have opened and why it cannot:
|
||||
|
||||
```
|
||||
(LOAD GAME) opens a screen this export does not carry:
|
||||
The save-slot list is GP_SAVE_LOAD, not in this export. Destination MEASURED.
|
||||
```
|
||||
|
||||
**EXTRAS is the only Ⓐ-into-a-submenu this milestone can walk**, which is why the
|
||||
P5 gate rests on it.
|
||||
|
||||
`NEW GAME` is a deliberate gap of a different kind: the real chain is
|
||||
NEW GAME → DIFFICULTY → SELECT DATA → the `S00A` movie, and the port **jumps to
|
||||
the movie**, printing the two screens it skipped. That is a gap, stated out loud;
|
||||
nobody should read the port's behaviour there as the game's.
|
||||
|
||||
## 4. What this container distorts
|
||||
|
||||
* **No GPU.** 720p Theora decodes **+6.7 % … +6.9 % slower than real time** here
|
||||
(5 runs, both movies, on a quiet box). The boot's printed seconds carry that
|
||||
deficit. It is a property of the machine, not of the port.
|
||||
* **No sound card.** Godot falls back to a dummy driver, so **you will hear
|
||||
nothing**. The audio is present and measurable —
|
||||
`docs/port/AUDIO-VERIFICATION.md` answers every audio question without a
|
||||
device, and `tools/port/verify-menu-audio` asserts it — but *"I heard it"* is
|
||||
not available in here.
|
||||
* **A leaked-object warning at exit** is engine-side, not the port's. Measured:
|
||||
releasing every reference the port owns moves the count from 8 to 8.
|
||||
|
||||
## 5. Modding
|
||||
|
||||
`data/mods/` shadows `export/` by path. Each override is announced as it is read,
|
||||
and at the end of a run any file that **can never apply** is listed:
|
||||
|
||||
```
|
||||
mod: sprites/title/main_menu/ptbase.png <- data/mods/...
|
||||
mods: 1 file(s) in data/mods can shadow NOTHING -- no such path in the export:
|
||||
inert: sprites/title/TYPO_menu/pteff05.png
|
||||
```
|
||||
|
||||
A file whose path exists in the export but was simply not read this run is **not**
|
||||
listed. See `docs/port/MODDING.md` for the five rules the asset tree keeps.
|
||||
|
||||
## 6. Where the work is, and what P5's gate is waiting on
|
||||
|
||||
**P5's gate is the only one that needs a person, and it is not waiting on code.**
|
||||
|
||||
Everything above runs from `auto/port-p6-audio`.
|
||||
|
||||
🔴 **This section used to quote counts — "256 commits ahead, 58 files" — and they
|
||||
were stale the moment they were committed, because committing them incremented
|
||||
the count.** By the time anyone read it, it said 256 and the answer was 258. A
|
||||
number written into a document meant to inform a decision **decays with every
|
||||
commit either agent makes**, and the Decoder hit the same thing in their own
|
||||
merge-state page one message after recording the class.
|
||||
|
||||
**So what follows are the invariants, which do not move, and the commands to
|
||||
re-derive anything that does.**
|
||||
|
||||
| invariant | check | **passes when** |
|
||||
|---|---|---|
|
||||
| `main` is an **ancestor** of this branch — a fast-forward, nothing to resolve | `git merge-base --is-ancestor origin/main HEAD; echo $?` | prints **`0`**. ⚠️ The command itself prints **nothing** on success — without the `echo` a reader cannot tell success from failure |
|
||||
| `main` is an ancestor of the Decoder's branch too | `git merge-base --is-ancestor origin/main origin/auto/build-ordinal-audit; echo $?` | prints **`0`**, same caveat |
|
||||
| the two change sets touch **zero files in common** | `comm -12 <(git diff --name-only origin/main...HEAD \| sort) <(git diff --name-only origin/main...origin/auto/build-ordinal-audit \| sort) \| wc -l` | prints **`0`** |
|
||||
| merging both produces **no conflicts** | `git merge-tree --write-tree HEAD origin/auto/build-ordinal-audit \| wc -l` | prints **`1`** — one line is the tree id; conflicts would follow it. **Read-only: this merges nothing** |
|
||||
|
||||
**Last run here: `0`, `0`, `0`, `1`.** A command published without a pass
|
||||
condition is half a check — the reader gets a number and no way to know whether it
|
||||
is the right one — so each row states what the right one is.
|
||||
|
||||
📌 **So the sentence is not "N commits behind", which sounds like something to
|
||||
schedule. It is: two fast-forwards over disjoint file sets, mergeable in either
|
||||
order with zero conflicts.** Counts if you want them:
|
||||
`git rev-list --count origin/main..HEAD`.
|
||||
|
||||
### What a person is actually being asked to do
|
||||
|
||||
1. `godot --path port -- --boot --play`, then walk §2's table.
|
||||
2. Say whether it behaves as described. **Not whether it matches the game** —
|
||||
that comparison is the oracle's job and is already asserted by
|
||||
`tools/port/check-all`.
|
||||
3. If it does, P5's gate is met and nothing else is blocking P6, which asserts its

# The blend map is deleted — and adopting the decoded field found a counter-example
|
||||
|
||||
**Status:** ✅ **adopted.** ❌ **My counter-example failed — the bit is right and the
|
||||
regression is a metric artefact.** See the last two sections.
|
||||
Port at `7dd754f` + this commit; formats pinned at `formats-pin-2026-09-01`;
|
||||
HANDOFF on this branch answers `9ca1eb5`.
|
||||
|
||||
`PORT-MISSION` §3: *"When the RE agent later decodes something you had authored,
|
||||
delete the authored entry and let the exporter emit it. That deletion is the
|
||||
measure of progress."* This is that deletion.
|
||||
|
||||
## What changed
|
||||
|
||||
| | before | after |
|
||||
|---|---|---|
|
||||
| source | `authored/rendering.json` → `additive_elements`, keyed by **screen name** | `blend_additive` per element, emitted by the exporter |
|
||||
| origin | transcribed from the Decoder's per-draw `RB_BLENDCONTROL0` log | **decoded** — `T8aD +0x04` bit `0x02` |
|
||||
| reach | three screens somebody drove the game to | every screen on the disc |
|
||||
|
||||
The pin bump is its own commit (`7dd754f`). The exporter emits `blend_additive`
|
||||
on `Element` **and** on nested focus/leaf elements — both spellings of the
|
||||
accessor are needed, because a button's focused variant is reached through
|
||||
`focus_link` and `ptbtn00f.t32` is in `build.sprites` while no element carries it
|
||||
as `sprite`. `ptbtn00f` is exactly the sharp case: the plate is alpha-over and
|
||||
its own glow is additive, on one screen in adjacent draws.
|
||||
|
||||
## The check before the swap — the map was a subset, not the answer
|
||||
|
||||
Over `main_menu`, `extras`, `press_start` and `title`:
|
||||
|
||||
| | count |
|
||||
|---|---|
|
||||
| map says additive **and** the disc agrees | **15** |
|
||||
| map says additive and the disc does **not** | **0** — no contradictions |
|
||||
| disc says additive and the map did not | **17** |
|
||||
|
||||
Nothing transcribed was wrong. It was **incomplete and was being read as
|
||||
complete**. The 17 include:
|
||||
|
||||
* `pteff03` / `pteff03a` — the sweep **leaves**. `draw_leaf_for` means those are
|
||||
what actually reach the screen while the map listed their parents
|
||||
`ptloop01`/`ptloop02`. (Both parent and leaf carry the bit, so this one turned
|
||||
out to change nothing — established below, not assumed.)
|
||||
* **twelve on `title`**, where the map was deliberately empty. The port has been
|
||||
drawing every title effect alpha-over.
|
||||
|
||||
**And it answers `BLOCKED.md` H6 with no capture at all.** The JP asymmetry — the
|
||||
port drawing `main_menu` additive and `main_menu_jp` alpha-over, asserting by
|
||||
omission that the JP build differs — was an artefact of a name-keyed map. The bit
|
||||
is on the disc for every screen at once.
|
||||
|
||||
## 🔴 The regression, which is one element
|
||||
|
||||
Scored against the oracle captures, on the GPU, before and after:
|
||||
|
||||
| screen | before | after | Δ |
|
||||
|---|---|---|---|
|
||||
| **`main_menu`** | 10.88 | **13.02** | **+2.14** |
|
||||
| **`main_menu_options`** | 11.56 | **13.57** | **+2.01** |
|
||||
| `extras` | 13.10 | 13.10 | — |
|
||||
| `title` | 14.11 | 14.11 | — |
|
||||
| `title_plate`, `title_band`, both splashes | unchanged | unchanged | — |
|
||||
|
||||
**The scores are deterministic** — two further runs gave 13.02 / 13.10 / 13.57
|
||||
to the digit — so this is a real change, not sampling noise.
|
||||
|
||||
### It is `pteff10`, isolated
|
||||
|
||||
* `main_menu`'s only newly-additive **top-level** element is `pteff10`.
|
||||
* `extras` has **no** newly-additive top-level element, and its score did not
|
||||
move. That is the control: the same change applied to a screen with nothing new
|
||||
moves nothing.
|
||||
* The leaf rule was tested separately by disabling it — `main_menu` stayed at
|
||||
13.02, so `pteff03`/`pteff03a` are **not** the cause. That prediction of mine
|
||||
failed and the rule was restored, being provably neutral here.
|
||||
|
||||
`title` did not move despite twelve newly-additive elements, which is consistent:
|
||||
`verify-capture` poses at settle `t=198`, and the title's effect quads —
|
||||
`ptlogo_back2eff1…5`, `ptlogoall_eff`, `pteff01` — are transparent there.
|
||||
|
||||
### 🔴 WHY I THOUGHT THIS WAS A COUNTER-EXAMPLE — and it was not. Kept because the premise-check is the lesson
|
||||
|
||||
**Their own map lists `pteff10` as additive on `extras` and not on `main_menu`,
|
||||
and they logged both screens.** So either their per-draw log shows `main_menu`'s
|
||||
`pteff10` drawn alpha-over — a direct contradiction between a capture and the
|
||||
disc bit, on one element — or it was not drawn during that capture. The oracle
|
||||
comparison independently prefers alpha-over there.
|
||||
|
||||
❌ **Wrong, and the premise was the failure.** The oracle *does* measure it
|
||||
additive on `main_menu` — three sessions, every frame. What I read was a stale
|
||||
coverage table of theirs sitting upstream of its own correction. **I inferred
|
||||
"their log does not cover this" from a table, and called it a contradiction with
|
||||
a capture.** The lesson is not that the map was stale; it is that I treated a
|
||||
summary as the log. See the resolution at the foot of this page.
|
||||
|
||||
## Why the change ships anyway, stated rather than assumed
|
||||
|
||||
1. `main_menu` carries a **±3.78 capture-phase term** in the harness's own note —
|
||||
the capture caught the free-running sweep at an unknown phase. **+2.14 is
|
||||
inside that stated uncertainty** and cannot adjudicate a disc fact.
|
||||
`main_menu_options` is a sub-region of the same screen and inherits the same
|
||||
sweep.
|
||||
2. The decoded source is far better evidenced than the comparison that moved, and
|
||||
it **fixes two known defects** — twelve title effects drawn with the wrong
|
||||
blend, and a JP/EN asymmetry the port was asserting by omission.
|
||||
3. Fitting an exception for `pteff10` would put an authored entry back to make one
|
||||
number smaller. That is the move this project keeps having to undo.
|
||||
|
||||
🔴 **This was a known regression shipped deliberately, not an unnoticed one** —
|
||||
and the decision was right for a *stronger* reason than the one I used. Not only
|
||||
is +2.14 inside the ±3.78 phase term: the oracle had already adjudicated this
|
||||
element, so the metric is the thing disagreeing, not the render.
|
||||
|
||||
## What this does not claim
|
||||
|
||||
* That the bit is wrong. One element, inside a stated uncertainty, against a
|
||||
disc-wide check with an out-of-sample prediction.
|
||||
* That `pteff10` on `main_menu` and on `extras` are the same sprite. Not checked.
|
||||
* That the leaf rule is right — only that it is **neutral here**, so nothing in
|
||||
this page rests on it.
|
||||

# ❌ The counter-example failed, and the regression is RMSE's area-weighting
|
||||
|
||||
## The oracle had already adjudicated `pteff10`
|
||||
|
||||
`blend-bit-vs-oracle.txt` carries it on **both** screens — entry 5 (main menu)
|
||||
and entry 6 (extras), `+0x04 = 0x8832`, bit set, both labels read out of the
|
||||
guest command stream — and HANDOFF records it *"additive, in all three menu
|
||||
sessions, every frame."*
|
||||
|
||||
**My premise was a stale coverage table**, not a reading of the log. The
|
||||
correction existed; the wrong table was still visible upstream of it. So the
|
||||
adversarial attempt lands as **survived**: the claim is stronger for having been
|
||||
challenged, and the challenge cost one message.
|
||||
|
||||
⚠️ **And the regression was flagged on this exact element before I adopted it** —
|
||||
🟡 in HANDOFF: nearly exact under alpha-over in our render, additive in the game,
|
||||
*"the one row here your renderer does not independently corroborate."*
|
||||
|
||||
## But their explanation makes a prediction, so I checked it
|
||||
|
||||
If additive and alpha-over *nearly coincide* on a dim glow (max alpha 130) over a
|
||||
dark background, the score should barely move. **Mine moved 20 %.** That is a
|
||||
real tension and it was worth one measurement.
|
||||
|
||||
Diffing the two port renders — the only change between them is `pteff10`'s blend:
|
||||
|
||||
| | |
|
||||
|---|---|
|
||||
| pixels identical | 373 588 (**40.5 %**) |
|
||||
| pixels differing by > 3 | 330 794 (**35.9 %**) |
|
||||
| **maximum difference, anywhere** | **32 levels** |
|
||||
| pixels differing by ≥ 60 | **0** |
|
||||
| bounding box | x 288–993, full height |
|
||||
|
||||
**Their explanation holds and my scepticism does not.** No pixel moves by more
|
||||
than 32/255 — 12.5 % — which is "nearly coincide" measured rather than asserted.
|
||||
What moved the RMSE is **area**: a third of the frame shifting slightly.
|
||||
|
||||
## The thing worth keeping: RMSE cannot tell broad-and-shallow from narrow-and-deep
|
||||
|
||||
`raw-rmse` is area-weighted, so **a shallow change over a third of the frame
|
||||
moves it far more than a deep change over a few hundred pixels** — and the number
|
||||
alone does not say which you have. 10.88 → 13.02 reads like a serious regression
|
||||
and is a difference invisible to an eye.
|
||||
|
||||
This bears on every `verify-capture` number in the corpus, not just this one. A
|
||||
row that moves should be asked *"broad or deep?"* before it is called a
|
||||
regression, and that costs one histogram.
|
||||
|
||||
## What I did NOT do: exclude the element
|
||||
|
||||
The Decoder suggested considering `pteff10` excluded from the metric with the
|
||||
reason stated, rather than letting 13.02 sit as debt. **I have not**, and the
|
||||
measurement above is why: max-32 over a wide area is a *characterised* difference,
|
||||
not an unscoreable one. Excluding it would remove the only signal that would fire
|
||||
if the bit were ever wrong on some other screen — and the reason to exclude
|
||||
("the metric can't distinguish these") is now known to be false; it distinguishes
|
||||
them fine, it just weights them by area.
|
||||
|
||||
**The 13.02 stands, with its explanation attached.** That is cheaper than an
|
||||
exclusion nobody will revisit.

# 🔴 Provenance: the oracle behind this adoption had a container-only instrument
|
||||
|
||||
Recorded 2026-09-01 at shutdown, from the Decoder's own audit of their `/canary`
|
||||
checkout, not from anything visible on this side.
|
||||
|
||||
This page deleted an authored map on the strength of `ui-blend-mode-decoded.md` —
|
||||
35 elements against `RB_BLENDCONTROL0` read out of the guest command stream, zero
|
||||
errors both ways, plus an out-of-sample prediction. **That evidence was not
|
||||
reproducible by anyone who cloned this repository.** The Canary logger commit
|
||||
that emits `blend=` per draw lived only in their container; without it a draw log
|
||||
records **no blend state at all**, so the oracle could not be re-derived at all —
|
||||
not approximately, not at reduced confidence. Not at all.
|
||||
|
||||
It is reproducible now: four container-only logger commits are exported as
|
||||
patches under `tools/canary-patches/` **on `auto/frame-blend-draw-path`**, with a
|
||||
rebuild recipe. ⚠️ Named without a resolvable path on purpose — that directory is
|
||||
not in this checkout, and citing it as one would be the exact defect
|
||||
`check-citations` exists to catch.
|
||||
|
||||
## What this does and does not change
|
||||
|
||||
* **It does not weaken the adoption.** The measurement was real when made and is
|
||||
now reproducible. Nothing here is retracted.
|
||||
* **It does change what "decoded" was resting on.** For the window between the
|
||||
adoption and the export, this port had deleted an authored entry in favour of a
|
||||
field whose supporting oracle no one else could regenerate. The map was the
|
||||
*worse* of the two — a screen-name table that could not answer for a screen
|
||||
nobody drove to — so the trade was still right. But it was a trade made against
|
||||
an instrument, and the instrument's reach was smaller than the finding's.
|
||||
|
||||
📌 **The generalisation, and it is theirs:** a finding is only as portable as the
|
||||
tool that produced it, and a reproduce recipe that reads as complete is the
|
||||
dangerous kind. Theirs *looked* complete — it named shas — which is why four
|
||||
commits sat unexported while one was noticed.
|
||||
|
||||
⚠️ And the port cannot check this class from here. `check-citations` scans repo
|
||||
paths; an instrument living in another container is not a path at all. **The only
|
||||
defence available on this side is asking what produced a number before adopting
|
||||
it**, which is not a check and does not run.

# The committed captures are CROPS, not resamples — so pixel comparisons are like-for-like
|
||||
|
||||
**Status:** ✅ **measured, and it refutes a consequence rather than a finding.**
|
||||
Written 2026-09-02 by the Port; HANDOFF on this branch answers `9ca1eb5`.
|
||||
|
||||
## The claim under test
|
||||
|
||||
The Decoder read Canary's cvars — `present_letterbox` defaults true,
|
||||
`present_safe_area_x/y` default to 100 — and concluded that the guest's
|
||||
1280×720 is scaled to the host window and letterboxed, which would explain the
|
||||
1279×675 game surface the corpus has measured without ever accounting for. The
|
||||
consequence drawn:
|
||||
|
||||
> *"Everything either of us measures off a PNG carries the resample — every RMSE
|
||||
> against a capture, every glyph count, every surface mean, and the
|
||||
> `motion-census` numbers on both sides."*
|
||||
|
||||
That is a caveat on a very large amount of shared evidence, so it is worth one
|
||||
measurement before anyone starts qualifying results with it.
|
||||
|
||||
## Pre-registered (R2)
|
||||
|
||||
> If the captures carry a scale, then **scaling** this port's 1280×720 render
|
||||
> down to 1279×675 should match a capture better than **cropping** it. If they
|
||||
> are crops, the reverse.
|
||||
|
||||
## Measured
|
||||
|
||||
`live-splash-publisher.png`, 1279×675, against the port's own 1280×720 render of
|
||||
the same screen:
|
||||
|
||||
| | RMSE vs the capture |
|
||||
|---|---|
|
||||
| render **cropped** to 1279×675 | **558.1** (0.85 %) |
|
||||
| render **scaled** to 1279×675 | **10 118.8** (15.4 %) |
|
||||
|
||||
**Cropping is 18× better.** A 0.9375 vertical scale would put every feature at
|
||||
the wrong row; it does not, and the residual under scaling is exactly what that
|
||||
misalignment looks like.
|
||||
|
||||
🔴 **So these captures do not carry a vertical resample**, and the corpus's
|
||||
pixel comparisons against them are like-for-like.
|
||||
|
||||
## What is refuted and what is not
|
||||
|
||||
**Refuted: the consequence.** *"Everything measured off a PNG carries the
|
||||
resample"* is false for the committed captures. Every RMSE, glyph count and
|
||||
surface mean taken against them compares pixels to pixels, not pixels to pixels
|
||||
through an uncharacterised filter.
|
||||
|
||||
**Not refuted: the cvar reading.** Canary may well letterbox by default; that is
|
||||
a statement about the emulator's configuration and this measurement says nothing
|
||||
about it. What it says is that **the capture path used for the corpus did not
|
||||
go through it** — the presenter was bypassed, the window was 1:1, or the
|
||||
screenshot tool cropped the letterbox away before saving. Which of those, nobody
|
||||
here has established.
|
||||
|
||||
📌 **A second, independent line already agreed and nobody connected it.**
|
||||
`ui-render-tone-curve.md` records that every committed capture aligns against
|
||||
our render at exactly `dy = 0, dx = 0` with correlation 0.9466. A vertical scale
|
||||
of 0.9375 cannot produce a zero-offset alignment. The evidence for "crop" was
|
||||
already in the corpus, one page away from the surface-size puzzle it explains.
|
||||
|
||||
And 1279×675 is what a crop looks like: one column and forty-five rows removed,
|
||||
top-aligned, which is what the corpus said years-of-notes ago — *"that is the
|
||||
screenshot tool's crop."*
|
||||
|
||||
## What this does not change
|
||||
|
||||
* **The gamma result stands and is the more useful half.** No transform on either
|
||||
side of the boundary: `VdGetCurrentDisplayGamma` is `kStub`, and the splash's
|
||||
own pixel shader is four ALU ops with no `pow`, no ramp, no lookup.
|
||||
* **The vertex-stream path is still the better instrument** where a question can
|
||||
be asked of it. It carries no shader, no render target, no resolve and no
|
||||
presenter, and that is why the Decoder's per-frame alphas are the game's
|
||||
values rather than pixels we measured.
|
||||
* **`motion-census` was never at risk.** A resample preserves change, so those
|
||||
numbers would have been comparable either way — the Decoder said so, and it is
|
||||
right regardless of this result.
|
||||
|
||||
## Reach
|
||||
|
||||
One capture, one screen, one comparison. It refutes "all captures carry a
|
||||
resample" because a single counter-example is enough for a universal, and it
|
||||
does **not** establish that no capture anywhere carries one.

# F5 and F6 — ready for a human check
|
||||
|
||||
**Why this file exists.** PROTOCOL's "work in units a human can check in a
|
||||
minute" asks for the question, what to look at, and what pass/fail mean,
|
||||
written down in one place. The investigation for F5 and F6 is long and lives in
|
||||
[`f6-what-starts-the-sweep.md`](f6-what-starts-the-sweep.md),
|
||||
[`plate-arrives-on-time-but-never-blinks.md`](plate-arrives-on-time-but-never-blinks.md)
|
||||
and the commit history (`ac1371c`, `af10a2e`, `2b802e0`, `94d761e`,
|
||||
`1628f0e`, `edf8979`). Nobody should have to read that to know what to watch.
|
||||
|
||||
**Both are implemented, verified on film (not stills), and out-of-sample
|
||||
tested** — a fresh boot the predictions had no hand in producing matched on
|
||||
every figure the port actually relies on
|
||||
(`edf8979`, `docs/re/f6-out-of-sample-RESULT.md`). Neither is signed off by a
|
||||
person yet. That is the ask.
|
||||
|
||||
## F6 — the glow no longer starts before the plate
|
||||
|
||||
**One sentence:** watch a boot; the traveling glow along the blue lines should
|
||||
be invisible until the `PRESS Ⓐ` plate is on its way in, not visible from the
|
||||
first logo frame.
|
||||
|
||||
**What changed:** the renderer was discarding the parent element's own alpha
|
||||
ramp (`0:0 70:0 100:255 238:255 250:0`) when drawing the glow's nested leaf.
|
||||
The glow now only draws once the parent has faded in — invisible to `t=70`,
|
||||
full by `t=100` — instead of being visible from `t=0`.
|
||||
|
||||
**Pass:** on a fresh boot, the sweeping glow is not visible during the two
|
||||
publisher/developer splash-adjacent early frames of the title build-in; it
|
||||
fades in alongside (not before) the rest of the plate's approach.
|
||||
**Fail:** the glow is visible streaking across the screen before anything else
|
||||
on the title has appeared.
|
||||
|
||||
**Not covered by this unit:**
|
||||
* The glow's *speed*, *path*, or whether it should be one streak or several —
|
||||
Unit e in `f6-what-starts-the-sweep.md` flags that the port draws exactly
|
||||
two full-height streaks and the human's original report described something
|
||||
that could be a population of smaller lights on individual PCB traces. That
|
||||
is unresolved and is a different question from *when* it starts.
|
||||
* Any fixed "lead time" between the glow and the plate — that number turned
|
||||
out not to be reproducible (0.0996–0.141 across three captures) and nothing
|
||||
is authored against it. F6 as originally reported ("starts too early") does
|
||||
not depend on that number; the fix is the alpha gate above.
|
||||
|
||||
## F5 — Ⓐ during the build-in snaps, it does not speed up
|
||||
|
||||
**One sentence:** during the title build-in (after the boot logos, before the
|
||||
`PRESS Ⓐ` plate normally appears), press Ⓐ once and watch the wordmark —
|
||||
it should cut straight to its finished pose in one frame, not animate faster
|
||||
toward it.
|
||||
|
||||
**What changed:** nothing new to watch for — this is a **confirmation ask**.
|
||||
The port's existing behavior (an instant cut, both light-sweep leaves
|
||||
restarting at their own declared opening pose in the same frame) was verified
|
||||
by frame-by-frame reading of submitted alpha values, which is the only
|
||||
instrument that can actually tell a one-frame cut from a several-frame
|
||||
acceleration — the human said themselves they could not tell by eye.
|
||||
|
||||
**Pass:** the artwork looks the same as the port's current behavior — an
|
||||
instant jump, not a visible speed-up.
|
||||
**Fail:** the artwork clearly animates faster (rather than cutting) toward the
|
||||
finished pose, which would mean the July measurement should be revisited.
|
||||
|
||||
**Not covered:** the exact frame Ⓐ targets, which is established as
|
||||
undecodable-with-no-observable-consequence (`docs/re/f5-snap-target-undecodable-with-reach.md` /
|
||||
the boot.gd comment above `settle_time()`) — there is a window `[160, 238)`
|
||||
where any value in it renders identically forever, so nothing is riding on the
|
||||
literal.
|
||||
|
||||
## What the port did this iteration
|
||||
|
||||
Nothing changed in code. This iteration re-read the state left by prior
|
||||
iterations, ran `tools/port/check-all` to confirm nothing regressed, and
|
||||
attempted to refute the F6 census claim ("the port renders exactly two
|
||||
moving lights, nothing else on the title declares positional travel") by
|
||||
re-deriving it independently from `export/screens/title/title.json` — every
|
||||
top-level element and every nested `.rat` leaf. **It survived**: only
|
||||
`ptloop01`→`pteff03` and `ptloop02`→`pteff03a` declare any positional travel
|
||||
at all; no other element or leaf has a `pos` keyframe that moves.

# 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=214–236**. 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 550–600) 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 128–131 — 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 254.0–256.9 turned out to be *the rows
|
||||
they had printed*, every twentieth frame, standing in for a population whose real
|
||||
first-cycle spread was 250.9–260.5.
|
||||
|
||||
**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 0.138–0.141 | **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.

# F1 — the menu repeats on a held direction: mechanism shipped, **rate deliberately not**
|
||||
|
||||
**Status:** ✅ mechanism implemented and wired. 🔴 **inert on purpose** — it does
|
||||
nothing until a measured repeat rate exists. Written 2026-09-02 by the Port.
|
||||
|
||||
## What was reported
|
||||
|
||||
Two statements from the human, both about the **real game**, a play-test apart:
|
||||
|
||||
> *"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."*
|
||||
|
||||
> *"Confirmed D-Pad does repeat when holding too."*
|
||||
|
||||
## The file predicted its own refutation
|
||||
|
||||
`gamepad.gd` carried this, written when the latch was added:
|
||||
|
||||
> *"Whether the real game repeats while a direction is held, and how fast, is
|
||||
> unknown… If the game does repeat, this is a difference a human will notice as
|
||||
> 'I have to flick it again', and the fix is a measured repeat interval — not a
|
||||
> guessed one."*
|
||||
|
||||
That is exactly what happened, in the words it predicted. **So
|
||||
one-step-per-deflection is no longer the conservative reading — it is a known
|
||||
defect**, and keeping it is choosing a wrong behaviour over an approximate one.
|
||||
|
||||
## What was built
|
||||
|
||||
| | |
|
||||
|---|---|
|
||||
| `Gamepad.held_direction()` | −1 / 0 / +1, polled from the **devices** |
|
||||
| `Gamepad.repeat_due(delta)` | one step or 0, per frame |
|
||||
| `Boot._menu_repeat(delta)` | calls it under the same guards a real press gets |
|
||||
|
||||
### Why it polls devices and not `Input.is_action_pressed`
|
||||
|
||||
`ui_up`/`ui_down` are bound to the stick axis at **Godot's 0.50 action
|
||||
deadzone**, while this port steps at the game's measured **0.61** (`ENTER`).
|
||||
Polling the action would repeat throughout the 0.50–0.61 band — the exact band
|
||||
`ENTER` exists to exclude — so the repeat would contradict the threshold on the
|
||||
same stick, on the same frame.
|
||||
|
||||
That is the input-map lesson from 2026-09-01 arriving in a new place: **assert
|
||||
the device, not the layer above it.** The stick reads from the latch
|
||||
`accepts()` already maintains, so the first step and the repeat cannot disagree
|
||||
about hysteresis; the d-pad reads `JOY_BUTTON_DPAD_UP/DOWN` directly, which the
|
||||
human's second report makes load-bearing rather than defensive.
|
||||
|
||||
### Why the guards are duplicated rather than shared
|
||||
|
||||
`_menu_repeat` re-applies the same four conditions `_unhandled_input` applies —
|
||||
no movie playing, a menu exists, its stack is non-empty, no transition pending.
|
||||
A repeat that could fire during a movie or mid-transition would be a **second,
|
||||
subtly different input path**, and the first thing this port learned about input
|
||||
is that a second path is where the defect hides.
|
||||
|
||||
## 🔴 And the rate is not shipped
|
||||
|
||||
An earlier draft of this change had `REPEAT_DELAY = 0.40` and
|
||||
`REPEAT_INTERVAL = 0.20`, with a paragraph explaining that they were authored.
|
||||
**They were removed rather than commented out**, on an explicit instruction:
|
||||
|
||||
> *"Take the RATE from the Decoder — do NOT ship a placeholder interval. An
|
||||
> invented rate here is indistinguishable from a measured one later, and this is
|
||||
> the exact field where that already cost us."*
|
||||
|
||||
The instruction is right and the draft was the named failure mode: the
|
||||
explanation would have merged, the numbers would have felt roughly right, and
|
||||
nothing downstream could have separated them from a measurement. `REPEAT_DELAY`
|
||||
is `-1.0`; `repeat_due()` returns 0 while `repeat_rate_known()` is false.
|
||||
|
||||
**One thing about the rate IS measured, and it narrows the question.** The game
|
||||
digitises the left stick to four direction bits at 61 % deflection, so it cannot
|
||||
see deflection magnitude at all — the repeat it drives *cannot* be
|
||||
faster-the-harder-you-push. That excludes the one competing model, so only two
|
||||
constants are open and a single measurement closes both.
|
||||
|
||||
## ⚠️ Adopting the rate breaks a green check, for the right reason
|
||||
|
||||
`tools/port/verify-input` asserts *"a held stick is ONE step, not six"*. That row
|
||||
passes today **because the feature is inert**, i.e. it asserts the absence of the
|
||||
repeat. When a rate is adopted a held stick should produce further steps and that
|
||||
row will go red.
|
||||
|
||||
It is not wrong and it should not be deleted in a hurry: it was written for the
|
||||
2026-09-01 jitter defect, so it will *look* like that bug returning. It has to be
|
||||
re-stated as "one step per deflection **plus** the measured repeat", with the
|
||||
jitter case still covered inside the delay window.
|
||||
|
||||
## What this does not claim
|
||||
|
||||
* That the repeat feels right. It cannot — it does not run.
|
||||
* Any rate, or any bound on one. "Medium pace" is a direction, not a number, and
|
||||
it is not recorded anywhere as data.
|
||||
* That the d-pad and the stick repeat at the *same* rate. Both repeat; nobody
|
||||
has said they match, and the code currently assumes one rate for both.

|
||||
|
||||
## 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.

# P7 — the new-game intro plays and returns to a defined state ✅
|
||||
|
||||
**Status:** ✅ **gate met, with an artifact.** Run 2026-09-01 by the Port at
|
||||
`4be90c2` + this commit; HANDOFF on this branch answers `9ca1eb5`.
|
||||
|
||||
`PORT-MISSION.md` P7: *"New-game intro video after NEW GAME | Plays, then returns
|
||||
to a defined state."*
|
||||
|
||||
The path had been **wired** for some time — `authored/flow.json` gives `ptbtn01`
|
||||
a `then_video: "S00A"`, a `skipped_chain`, and `after_video: {goto: "title"}`,
|
||||
and `S00A.ogv` is in the export. **Nobody had run it.** A milestone is done when
|
||||
its artifact exists, not when the wiring reads correctly, and this file is the
|
||||
difference.
|
||||
|
||||
## Pre-registered (R2)
|
||||
|
||||
> `--menu --script=accept` with focus on `NEW GAME` announces the skipped
|
||||
> `DIFFICULTY, SELECT DATA` chain, plays `S00A`, and returns to `title`.
|
||||
> Unskipped, `S00A` is 93.78 s of media, so it should end **on its own** at
|
||||
> ≈94 s and hand off.
|
||||
|
||||
## What happened
|
||||
|
||||
```
|
||||
menu on main_menu, focus ptbtn01
|
||||
script[1] accept at 1.00 s
|
||||
(NEW GAME) -> the real chain is DIFFICULTY -> SELECT DATA, then the movie.
|
||||
Neither screen is in this export.
|
||||
-> video S00A at 0.97 s (/work/export/video/S00A.ogv)
|
||||
+ voice S00A
|
||||
video ended at 94.13 s
|
||||
-> title (authored: authored)
|
||||
(after the movie) -> title
|
||||
overlay press_start raised, settles at t=236
|
||||
script complete after 96.83 s on title
|
||||
```
|
||||
|
||||
**94.13 s against 93.78 s of declared media — +0.35 s, 0.4 %.** It ends on its
|
||||
own, at the right time, and hands off. Both predictions held.
|
||||
|
||||
Artifacts: `s_00_start.png` (main menu, `NEW GAME` focused) and `s_01_accept.png`
|
||||
(the title with the plate up) — written to the scratchpad by `--shots`, not
|
||||
committed, because they are frames of the user's own disc.
|
||||
|
||||
## It genuinely decodes — checked, because "ends at the right time" does not prove it
|
||||
|
||||
A player that consumed 94 s of *time* while showing one frame would also "end at
|
||||
94 s". So the frame counts, at two window lengths:
|
||||
|
||||
| window | frames shown | of 2813 |
|
||||
|---|---|---|
|
||||
| 2.03 s | 45 | 2 % |
|
||||
| 18.91 s | **244** | 9 % |
|
||||
|
||||
Frames scale with the window — it is decoding, not stalled. **Sub-linearly
|
||||
though**, 22.2 fps early against 12.9 fps over the longer window, and that is
|
||||
the same software fill ceiling documented in
|
||||
[`port-frame-rate.md`](port-frame-rate.md); these two runs predate the GPU.
|
||||
|
||||
⚠️ **The counts are upper bounds and the port says so itself** — the log reads
|
||||
*"at most 244 of 2813 frame(s) shown"*. It cannot see inside `VideoStreamPlayer`,
|
||||
so it reports what it can bound rather than a number it cannot support.
|
||||
|
||||
## A free corroboration of the fill-rate finding
|
||||
|
||||
The unskipped run reports `main_menu: 5677 frames in 94.13 s — **60.3 fps**`.
|
||||
The screen never changes during a movie, so the rate line attributes the whole
|
||||
playback to it.
|
||||
|
||||
**The same process, in the same container, on the same screen: 60.3 fps while a
|
||||
full-screen video texture is on top, and 9.7 fps while drawing the menu's five
|
||||
additive full-screen quads.** That is the fill-rate conclusion arriving from a
|
||||
direction it was not designed for — one large textured quad is cheap, five
|
||||
additive ones are not — and it cost nothing to obtain.
|
||||
|
||||
## Two things this run surfaced that are not P7
|
||||
|
||||
* 🔴 **`4 ObjectDB instances were leaked at exit`.** Godot's own warning, on
|
||||
every run of this path. Small and at shutdown, so it costs a player nothing,
|
||||
but it is a real signal that something in the video/overlay teardown is not
|
||||
freed. **Not chased, recorded.**
|
||||
* 🟡 **The menu bed keeps playing under the movie.** The port prints this itself
|
||||
and it is already an open ask — *does the menu music duck?* — in
|
||||
`BLOCKED.md`. Left audible on purpose rather than guessed at.
|
||||
|
||||
## What this does not claim
|
||||
|
||||
* That the skipped chain is right. `DIFFICULTY` and `SELECT DATA` live in
|
||||
archives this milestone does not export; the port **announces the skip** rather
|
||||
than pretending the sequence is complete, which is the honest half of a gate it
|
||||
cannot fully reach.
|
||||
* That `after_video: title` is what the game does. It is **authored**, and its
|
||||
`why` says so: the game goes into Mission 1, and gameplay is out of scope
|
||||
(`PORT-MISSION` §7). "Returns to a defined state" is the gate; `title` is the
|
||||
state we defined.

# H3 — the `PRESS Ⓐ` plate: which half the lateness is in
|
||||
|
||||
**Status:** ✅ **both halves answered, and TWO of my own conclusions on this page
|
||||
were refuted within the hour** — the `5 units/frame` reading and the claim that
|
||||
`clock: "shared"` collapses. Both are struck in place rather than deleted,
|
||||
because both were confident and both were wrong for reasons worth keeping.
|
||||
The answers are the Decoder's `h3-units-per-frame-measured.md`,
|
||||
`origin/auto/frame-blend-draw-path` at `a482d9a`.
|
||||
Written 2026-09-01 by the Port, against `export/` regenerated from this
|
||||
checkout, `HEAD` = `6db49f5` (merge of `origin/main` `1af103d` and
|
||||
`origin/human/r1-retro-tick`). HANDOFF on this branch answers `9ca1eb5`.
|
||||
|
||||
The [play-test](../agents/PLAYTEST-2026-09-01.md) finding 3 says the plate
|
||||
arrives late and names three candidate causes: the **unit→seconds constant**
|
||||
(the Decoder's), the **clock origin** and **`rest.t`** (both ours). The brief
|
||||
asks which half it is, and how that was established. This page is the answer.
|
||||
|

|
||||
> instead of 3.93 s, which is the size of what the human reported.
|
||||
|
||||
## What the export actually declares
|
||||
|
||||
`export/screens/title/press_start.json`, build 2, one element `ptbtn00`:
|
||||
|
||||
| t | alpha | note |
|
||||
|---|---|---|
|
||||
| 0 | `0x00` | invisible, y = 560 |
|
||||
| 214 | `0x00` | still invisible, y = 550 — it has drifted up unseen |
|
||||
| **236** | `0xff` | **full** |
|
||||
| 238 | `0xff` | last opaque frame |
|
||||
| 244 | `0x00` | gone again |
|
||||
|
||||
`rest.t = 236`. `settle_window = [214, 236, 225]`.
|
||||
|
||||
🔴 **The corpus says the plate reaches `a=255` at `t=238`. It reaches it at
|
||||
`t=236`.** 238 is the last frame at full alpha, not the arrival. Every
|
||||
derivation quoting `238 − 118 = 120 units = 2.000 s` is really `236 − 118 =
|
||||
118 units = 1.967 s`. The port has been printing both halves of the
|
||||
contradiction in one sentence on every boot — *"plate reaches full alpha at
|
||||
t=236 … 120 units after …"* — which is what an unchecked literal beside a
|
||||
computed value looks like. Corrected in `boot.gd` and in `authored/flow.json`.
|
||||
It moves the reconciliation by 0.033 s and overturns nothing.
|
||||
|
||||
## Candidate 1 — `rest.t`. **Eliminated.**
|
||||
|
||||
`rest.t` cannot set the plate's arrival, because the arrival is a **declared
|
||||
keyframe**, not a rest pose. `ptbtn00` is transparent until `t=214` and opaque
|
||||
at `t=236` under its own ramp; `rest.t = 236` only chooses where `holding`
|
||||
parks it afterwards, and 236 *is* that ramp's own peak. Setting `rest.t` to any
|
||||
other value moves where the plate stops, never when it starts.
|
||||
|
||||
Confirmed against the running port rather than by reading: see the film below,
|
||||
where the plate's onset is bracketed by the declared `t=214` with `rest.t`
|
||||
untouched.
|
||||
|
||||
⚠️ This does **not** rehabilitate `rest.t` generally. It is still wrong for
|
||||
transients — `ptlogo_back2eff1` is a two-frame flash (0 at t52, `0xff` at
|
||||
t54–56, 0 by t58) and its `rest.t = 54` is the flash *peak*, so `rest()` leaves
|
||||
five of these burning at once. It is simply not in this defect's causal path.
|
||||
|
||||
## Candidate 2 — the clock origin. **Eliminated, and measured.**
|
||||
|
||||
Two things had to be true and both are:
|
||||
|
||||
**(a) The port's two builds share one clock exactly.** `_advance` sets
|
||||
`view.time_units = 0.0` and raises the overlay in the same call
|
||||
(`_overlay_due = _elapsed`), and the sequence path assigns
|
||||
`overlay.time_units = view.time_units` outright rather than integrating a second
|
||||
delta. Verified over a filmed boot: **85 of 85 title frames have
|
||||
`view_units == overlay_units` to three decimals**, from 7.812 to 679.182. There
|
||||
is no drift and no offset to find.
|
||||
|
||||
**(b) The title step begins when the previous step ends.** The film puts the
|
||||
video's end and the title's start at the same logged instant (7.86 s / 7.92 s
|
||||
across two runs), with no black hold between them.
|
||||
|
||||
## Candidate 3 — the unit→seconds constant. **NOT eliminated. It is the live one.**
|
||||
|
||||
🔴 **This section said "eliminated by sign" and that was wrong.** The argument
|
||||
was: for the port to be late the constant must be *larger* than 60 units/s,
|
||||
while the oracle presents at ~28.1 fps and the corpus measured the idle title at
|
||||
28.5 fps — both slower than nominal, so the game's units run slower, not faster.
|
||||
|
||||
**That conflates two different quantities.** A presentation rate converts a
|
||||
*measured wall-clock duration* into units. It says nothing about **how many
|
||||
units elapse per game frame**, which is the constant in question
|
||||
(`keyframe_units_per_second`, and `keyframe_time_unit` is listed as `unresolved`
|
||||
on every screen this export emits). The correction is recorded rather than
|
||||
edited away because the elimination it produced was confident and wrong.
|
||||
|
||||
And the Decoder's splash draw capture, landed the same day on
|
||||
`origin/auto/frame-blend-draw-path` at `3cc1b51`
|
||||
(`docs/re/data/splash-quad-timeline.txt`), gives an **independent handle on that
|
||||
constant** — from a screen with no bearing on the plate:
|
||||
|
||||
| interval, publisher splash | guest, observed | this export, declared | units/frame |
|
||||
|---|---|---|---|
|
||||
| companion (`Q7`) onset → sharp logo (`Q0`) onset | f4 → f7, **3 frames** | t=0 → t=15, **15 units** | **5.0** |
|
||||
| companion onset → its own peak | f4 → f7 (a=240), **3 frames** | t=0 → t=15 (a=255), **15 units** | **5.0** |
|
||||
| sharp logo onset → full alpha | f7 → f10, **3 frames** | t=15 → t=30, **15 units** | **5.0** |
|
||||
|
||||
Three intervals, three ways, **5 units per guest frame** — against the declared
|
||||
**2**.
|
||||
|
||||
## 🔴 STRUCK. It is 2 units per frame, and my 5 was an artefact of two things
|
||||
|
||||
Measured by the Decoder on `ptbtn00` itself — the plate, on the title, not a
|
||||
splash — in `h3-units-per-frame-measured.md` (`a482d9a`), against a
|
||||
pre-registration committed before the capture was read:
|
||||
|
||||
```
|
||||
label 5372 5373 5374 5375 [5376] 5377 5378 [5379] 5380
|
||||
alpha 46 69 92 115 — 197 220 — 255
|
||||
step +23 +23 +23
|
||||
```
|
||||
|
||||
`255 × 2 / 22 = 23.18`, and the plate's declared ramp is `t=214 → 236`, i.e.
|
||||
`T = 22`. **Three consecutive gap-free steps of exactly 23 is 2.0 units per
|
||||
frame on the nose.** Their prediction was 11 frames for the ramp and it measured
|
||||
10, inside a stated ±1. My 4.4-frame prediction is excluded by more than 2×.
|
||||
|
||||
**Why my three intervals all read 5, and why the agreement between them was
|
||||
worthless.** Two independent errors, both mine to have made:
|
||||
|
||||
1. **An alpha step is not a clock rate.** For a linear segment,
|
||||
`Δα per frame = 255 × (units per frame) / T`. Two elements with different
|
||||
declared segment lengths `T` show different `Δα` at an *identical* clock.
|
||||
Splash B's quads step 34 with `T=15`; the plate steps 23 with `T=22`; both
|
||||
are 2 units/frame. Reading a step as a rate is what produced the 2.7×.
|
||||
2. **My "onsets" were not onsets.** I took each quad's *first submission* as its
|
||||
`α = 0` time. On splash A, `Q7` and `Q0` are both already at **α = 85** when
|
||||
first submitted. So all three intervals started late — and by a *different*
|
||||
amount per element, because the bias scales with `T`. That the three then
|
||||
agreed with each other is not corroboration; they share the error.
|
||||
|
||||
The three "independent" intervals were one measurement made three times with the
|
||||
same two biases. That is the shape I should have checked for and did not.
|
||||
|
||||
⚠️ The Decoder records the published `splash-quad-timeline.txt` having no `T`
|
||||
column as their own defect, now fixed. That does not make the inference mine any
|
||||
less: **the arithmetic was sound and the premise was not, and a premise handed
|
||||
to me is still a premise I used.**
|
||||
|
||||
⚠️ **Two caveats, and they are why this is asked rather than acted on.** The
|
||||
capture's frame index **skips** — 5, 8 and 12 are absent from Q7's eight draws —
|
||||
and whether those are frames where the quad was genuinely not submitted or
|
||||
presents the logger dropped changes the arithmetic. And the present rate during
|
||||
a splash is not established.
|
||||
|
||||
### 🔴 And it collides with the oracle's own plate measurement
|
||||
|
||||
The two captures cannot both be read at face value:
|
||||
|
||||
| capture | implies |
|
||||
|---|---|
|
||||
| `title-plate-delay-measured.md` — 118 units in 2.135 s | **~55 units/s** |
|
||||
| `splash-quad-timeline.txt` — 15 units in 3 frames | **~150 units/s** at 30 fps |
|
||||
|
||||
A factor of **2.7** between two measurements taken off the same game by the same
|
||||
agent, on two different screens. Either the two screens' keyframes are in
|
||||
different units, or one of the two readings has an anchor wrong — which is the
|
||||
same shape as the `t=118` / `t=160` question below. **Both are oracle
|
||||
measurements and neither is the port's to resolve.** Asked in
|
||||
[`BLOCKED.md`](BLOCKED.md) H3.
|
||||
|
||||
## The film — and the instrument had to be fixed first
|
||||
|
||||
`--film` scheduled frame `n` for `n × interval` and reported nothing. One
|
||||
1280×720 `save_png` under llvmpipe costs ~0.24 s, so **a request for 0.05 s
|
||||
delivered 247 frames in 60 s where 1 200 were asked for** — an achieved 4.1 fps
|
||||
against a requested 20 — and the deficit accumulated silently into the frame
|
||||
index. `f_071.png` still looked exactly like the frame that was meant to be
|
||||
3.55 s in.
|
||||
|
||||
[`TEMPORAL-VERIFICATION.md`](../agents/TEMPORAL-VERIFICATION.md) §1 is explicit
|
||||
that this is not a slow capture but a *different* one, and that an instrument
|
||||
which cannot report its own completeness may not be trusted (R3). So `--film`
|
||||
now writes `<film>_frames.tsv` — one row per frame carrying the elapsed second
|
||||
it was **actually** taken at, the second it was **requested** for, the lag
|
||||
between them, and both builds' clocks — appended and flushed as it goes, so a
|
||||
run killed by `timeout` still leaves a complete index. It prints the achieved
|
||||
rate against the requested one every 40 frames. The schedule is deliberately
|
||||
**not** rebased onto `_elapsed`: catching up would hide the shortfall, which is
|
||||
the defect.
|
||||
|
||||
The run this page rests on: requested 20 fps, **achieved 15.9 fps for the first
|
||||
120 frames and 11.3 fps by frame 200**, lag reaching 8.7 s. Stated because the
|
||||
numbers below are quoted against `view_units` — the port's own timeline, which
|
||||
the index records per frame — and never against a wall-clock instant.
|
||||
|
||||
### Pre-registered, before looking (R2)
|
||||
|
||||
> Filming the boot, measured from the frame the title step begins, the plate
|
||||
> region stays at its background floor until **t=214**, rises over **22 units**,
|
||||
> and plateaus at **t=236**. Accept ±2 frames at each end.
|
||||
|
||||
### What it did
|
||||
|
||||
Region = the plate's own quad, x 127–640, y 525–575 (`pos [383,550]`,
|
||||
`pivot [256,25]`, sprite 513×50). Mean of the crop, one row per filmed frame:
|
||||
|
||||
| `view_units` | region mean | |
|
||||
|---|---|---|
|
||||
| 7.8 → 143.8 | 0.13765, **flat to 5 decimals** | nothing there |
|
||||
| 151.9 → 207.8 | 0.13773 → 0.14341 | a slow 4 % drift, build 4's own |
|
||||
| **207.8 → 215.3** | 0.14341 → **0.15348** | ⬅ the step; brackets the declared **214** |
|
||||
| 215.3 → 239.8 | → 0.21254 | the ramp |
|
||||
| 239.8 → 279.3 | → 0.24766 | plate full at 236; the rest is `ptbtn00f` |
|
||||
|
||||
The onset is bracketed between 207.8 and 215.3 at a frame spacing of ~7.5 units,
|
||||
i.e. **within one frame of the declared 214**, and `rest.t` was never touched.
|
||||
Prediction held.
|
||||
|
||||
After 236 the region keeps oscillating — peaks near `u` 279 and 407, troughs
|
||||
near 343 and 479, a period of **~128 units** against `ptbtn00f`'s declared
|
||||
`loop_length_units = 120`. That is the focus glow looping, not the plate, and it
|
||||
is an ordering-and-period check that survives the drifting capture rate.
|
||||
|
||||
## So where the port lands against the oracle
|
||||
|
||||
`docs/re/title-plate-delay-measured.md` is **not in this checkout** — it is on
|
||||
`origin/auto/no-disc-and-menu-captures`, added at `fb536df` and cited by
|
||||
`authored/flow.json` at `5b0a6e6`. Read there:
|
||||
|
||||
| | run 1 | run 2 | **the port** |
|
||||
|---|---|---|---|
|
||||
| settled → plate | 2.138 s | 2.132 s | **1.967 s** (118 units at 60/s) |
|
||||
| first drawn → plate | 3.781 s | 4.263 s | **3.933 s** (236 units) |
|
||||
|
||||
On the interval the oracle measured deliberately, the port is **0.17 s early**.
|
||||
On the interval the oracle explicitly says not to use, the port sits **between
|
||||
the two runs**. No number anyone has taken makes this port's plate late.
|
||||
|
||||
**The human watched both and says late, and that observation stands.** At
|
||||
60 units/s the port reproduces every figure the plate capture carries — which is
|
||||
the point: *reproducing that capture is not the same as being right*, because
|
||||
the splash capture says the unit is 2.5× off and would put the port 2.4 s late.
|
||||
The two cannot both hold. The human's eye agrees with the splash capture.
|
||||
|
||||
## 🔴 WITHDRAWN: my claim that the t=160 anchor collapses `clock: "shared"`
|
||||
|
||||
The section below asked which anchor the glyph counter corresponds to and said,
|
||||
of the t=160 answer, *"the shared-clock premise does not reproduce the
|
||||
measurement at all and `clock: "shared"` is open"*. **The Decoder answered
|
||||
t≈160–176 — candidate B — and then repeated my consequence back to me**, noting
|
||||
correctly that what it costs the port's model is the port's problem and not
|
||||
evidence against their measurement.
|
||||
|
||||
**They were right to report it and I was wrong to have claimed it.** I computed
|
||||
the collapse by comparing the declared 76 units against **2.135 s**, and 2.135 s
|
||||
is the single number the same page identifies as in dispute — their two captures
|
||||
disagree about frames→seconds by ~2.9×. *Falsifying a model with the quantity
|
||||
that is itself under dispute* is the error, and it is the second time on this
|
||||
page I reasoned confidently from a premise I had not checked.
|
||||
|
||||
Against the **new** capture, in its own labels rather than in seconds,
|
||||
shared-clock holds:
|
||||
|
||||
| declared, shared clock | capture | at the plate ramp's own measured 2.2 units/label |
|
||||
|---|---|---|
|
||||
| `ptcopyright` full (t=160) → plate α=0 (t=214) = **54 units** | 5350 → 5370, **20 labels** | 44 units |
|
||||
| `ptcopyright` full (t=160) → plate α=255 (t=236) = **76 units** | 5350 → 5380, **30 labels** | 66 units |
|
||||
| the plate's own ramp (t=214 → 236) = **22 units** | 5370 → 5380, **10 labels** | — (this is the calibration) |
|
||||
|
||||
Both intervals come out **short of declared by 13–19 %, in the same direction**,
|
||||
against a claimed collapse of ~1.7×. And the residual has a named candidate the
|
||||
Decoder supplies: **empty labels advance the clock by more than one step**, they
|
||||
are about one label in five, and the two intervals contain different fractions of
|
||||
them (3 of 20, and 6 of 30). Modelled with empties carrying ~4 units the two
|
||||
reconstruct at 46 and 72 against 54 and 76.
|
||||
|
||||
**So `clock: "shared"` is not falsified and the port keeps it.** It is not
|
||||
*confirmed* to better than ~20 % either, and this page does not claim that. What
|
||||
it is no longer is "collapsed on the port's own account".
|
||||
|
||||
## A second anchor question, also the Decoder's — ✅ ANSWERED: it is t=160
|
||||
|
||||
**What does the oracle's "title settled" correspond to on the declared
|
||||
timeline?** It is defined operationally — *"glyph counter first reads its
|
||||
no-plate value 154"* — and our export offers **two** anchors, 42 units apart:
|
||||
|
||||
| anchor | what it is | settled → plate | vs measured 2.135 s |
|
||||
|---|---|---|---|
|
||||
| **t = 118** | `pteff01`, `pteff02`, `ptlogoall_eff` end their ramps together | 118 units = 1.967 s | −8 % |
|
||||
| **t = 160** | `ptcopyright` reaches full alpha — the **last** element to finish building in, and the only one made of **glyphs** | 76 units = 1.267 s | −41 % |
|
||||
|
||||
The port's reconciliation picked 118. The port's own `settle_time()` returns
|
||||
**160** and the boot prints `settles at t=160` — so the two notions disagree
|
||||
inside one binary. And the oracle's anchor is a *glyph* counter, while the thing
|
||||
that finishes at 160 is a *line of text*.
|
||||
|
||||
If the anchor is 160, the shared-clock premise does not reproduce the
|
||||
measurement at all and `clock: "shared"` in `authored/flow.json` — which the
|
||||
port authored from arithmetic and nobody has ever measured — is open. If it is
|
||||
118, the reconciliation stands and H3 is not a timing defect.
|
||||
|
||||
**Answered from the draw stream** (`a482d9a`): `ptcopyright` reaches α=255 at
|
||||
label 5350, which calibrates to **t ≈ 168** on the plate's own ramp (t ≈ 176 at a
|
||||
flat 2.0/label). Candidate B is 8–16 units away; candidate A is 50–58. It is B.
|
||||
|
||||
📌 And a caution from the same stream that this port should hold onto: **the
|
||||
sweep leaves never settle.** The two off-screen-wide quads translate
|
||||
monotonically through every label examined and are still moving when the plate
|
||||
arrives. *"The title has settled"* can only ever mean **the build-in elements
|
||||
have finished**, never *the screen has stopped changing* — which is the same
|
||||
distinction that `rest.t` keeps getting wrong.
|
||||
|
||||
### 🔴 ALL FOUR NAMED CAUSES ARE NOW DEAD, AND THE HUMAN'S OBSERVATION IS NOT
|
||||
|
||||
**The rate is measured: 56.8 units per guest second** (`units-per-second-measured.md`,
|
||||
control passing at 1.15 %, two elements agreeing at one clock — `ptbtn00` at
|
||||
657.9 α/s and `ptcopyright` at 650.4 α/s, which puts `ptcopyright`'s segment at
|
||||
`T = 22.25`, a round declared length nobody fitted). **30 and 120 are both
|
||||
excluded.**
|
||||
|
||||
At 56.8 units/s the plate's `t = 236` lands at **4.15 s** after clock zero,
|
||||
against the port's **3.93 s**. The port is fractionally **early**. So:
|
||||
|
||||
| candidate | verdict |
|
||||
|---|---|
|
||||
| `rest.t` | eliminated — the arrival is a declared keyframe |
|
||||
| clock origin | eliminated — 85/85 frames share one clock |
|
||||
| the anchor (t=118 vs t=160) | answered: t=160, and `clock: "shared"` survives it |
|
||||
| **the unit→seconds constant** | **eliminated — 56.8 measured; the port is early, not late** |
|
||||
|
||||
**Nothing named in the play-test explains what the human saw, and this page says
|
||||
so rather than quietly closing H3 green.** The observation stands and is now
|
||||
unattributed. Two things it could still be, neither of them the plate's own
|
||||
timing and neither established here:
|
||||
|
||||
* **what "late" was measured against.** Every number above is relative to the
|
||||
title's clock zero. A player experiences the plate relative to the *boot*, and
|
||||
the port's boot reaches the title at 7.86 s only because `--skip-at` presses Ⓐ.
|
||||
🔴 **On the play-test build Ⓐ was not bound to the pad at all**, so that human
|
||||
could not skip the 137 s intro — the run they judged is not the run any of
|
||||
these measurements describe.
|
||||
* **the splash dwells.** The rate's reach is the **title**. The splashes are a
|
||||
different `GamePart` and nothing yet shows they tick at 56.8; the Decoder has
|
||||
reading their `T` off the disc as a next item.
|
||||
|
||||
### The route that is dead regardless
|
||||
|
||||
🔴 **`units = 2 × frames` must not be used anywhere.** The same animation takes
|
||||
21 frame labels in one capture and 33 in another, and a splash logo steps
|
||||
`+136,+34` in one run and `+17,+51,+34,+34,+17,+17` in the other; a fixed
|
||||
per-frame increment cannot do that. The 2 was one run's frame pacing.
|
||||
|
||||
✅ **Audited, and the port never did this.** `boot.gd` advances
|
||||
`time_units += delta * units_per_second` off delta time. The retirement cost this
|
||||
port a *justification* in `authored/timing.json`, not a behaviour — and the
|
||||
justification's second leg (12 declared units against a 0.14–0.30 s measured
|
||||
black plateau, 40–86 units/s, no frames in the chain) never depended on it.
|
||||
|
||||
### What was still open, before the rate landed
|
||||
|
||||
`units/second = units/frame × guest fps`. The first factor is now **2**. The
|
||||
second is not established: **2 × 30 = 60** (what this port uses) and
|
||||
**2 × 60 = 120** (which puts the plate at **1.97 s** instead of 3.93 s — the size
|
||||
of what the human reported). The Decoder's capture ran at 27.2 labels/s, which is
|
||||
Canary's presentation rate and cannot separate a 30 Hz guest at full speed from a
|
||||
60 Hz guest at half. **They asked the port not to change 60 units/s on their
|
||||
account yet, and it has not.** Asked in [`BLOCKED.md`](BLOCKED.md) H3.
|
||||
|
||||
## Refutation attempts this iteration
|
||||
|
||||
| claim | whose | outcome |
|
||||
|---|---|---|
|
||||
| the title's settle window is `[160, 236]` | Decoder, `5b0a6e6` | ✅ **survived** — our exporter still computes `[160, 236, 198]` under the corrected record layout |
|
||||
| *"`ptlogo1` rests at t=251 and stops moving at t=42"* | Decoder, `5b0a6e6`, and the headline evidence for `rest.t ≠ settle` | ❌ **refuted on its evidence** — in the current export `ptlogo1.rest.t` is **42**, equal to when it stops moving. The record-layout fix repaired exactly this element. The *conclusion* survives on other elements (`ptlogo_back2eff1`, `pteff00`); the example no longer supports it |
|
||||
| *"`ptbtn00` reaches a=255 at t=238"* → `120 units` | the Port's own | ❌ **refuted** — 236, so 118 units |
|
||||
| *"build 4 is still fading up from black until t=261; `pteff00` is 7 % opaque at 243"* | the Port's own | ❌ **refuted** — `pteff00` is opaque at t=0, clear by **t=16**, transparent until 261, then fades **to** black by 269. At t=243 it is 0 % opaque. The comment had the direction backwards |
|
||||
|
||||
## What this does not settle
|
||||
|
||||
* Whether the human's "late" is a real offset the corpus has not measured. It
|
||||
is not reconciled by anything here, and no measurement contradicts it either.
|
||||
* The `t=118` / `t=160` anchor. Asked, not guessed.
|
||||
* Whether the plate **pulses** after arrival. The port holds it; the corpus
|
||||
measures a ~2.24 s pulse. Filed already in `flow.json`'s `no_pulse_why`.
|
||||
* Finding 4 (the splash fade/blur) is the Decoder's this iteration — it said so
|
||||
on the message channel and is on `auto/frame-blend-draw-path`.
|
||||
|
||||
|
||||
---
|
||||
|
||||
# The splash blur is an ASSET, not a pass — and this port already draws it
|
||||
|
||||
Added the same iteration, after the Decoder answered play-test finding 4 from
|
||||
GPU state (*no post-process on either splash*, `auto/frame-blend-draw-path` at
|
||||
`3cc1b51`) and the human added the observation that **the logos go from blurred
|
||||
to clear/sharp, in about one second**.
|
||||
|
||||
Those two are not in tension. They resolve each other:
|
||||
|
||||
> **Every logo ships a second, pre-blurred copy of itself, ~21 × 20 px larger
|
||||
> and concentric, which is drawn alone first and crossfades out as the sharp
|
||||
> logo fades in.** That is "blurred → sharp" with no post-process pass, no
|
||||
> blur shader and no second render target.
|
||||
|
||||
Measured off `export/sprites/title/`:
|
||||
|
||||
| logo | sharp | companion | position offset | concentric? |
|
||||
|---|---|---|---|---|
|
||||
| `palogo_gamearts` | 500 × 71 | 521 × 91 | (−11, −10) | ✅ |
|
||||
| `palogo_seta` | 240 × 89 | 261 × 110 | (−10, −11) | ✅ |
|
||||
| `palogo_anima` | 388 × 136 | 407 × 156 | (−11, −9) | ✅ |
|
||||
| `palogo_sqex` | 666 × 68 | 686 × 89 | (−10, −11) | ✅ |
|
||||
|
||||
## 🔴 "The port applies no blur at all" is false, and it came from this page's own side
|
||||
|
||||
[`BLOCKED.md`](BLOCKED.md) H2 and the play-test both record *"The port draws the
|
||||
splash from the declared keyframe alphas only. It applies **no blur at all**."*
|
||||
The port does not apply a post-process blur — but it draws all seven quads of
|
||||
the developer splash including the three blurred companions, and it has been
|
||||
doing so all along. A frozen sweep across the build-in, one deterministic
|
||||
capture every 3 units (the human's "take a series of quick screenshots within
|
||||
the short animation span", done without a clock at all):
|
||||
|
||||
| `t` | units | drawn |
|
||||
|---|---|---|
|
||||
| 0.00 s | 0 | background only |
|
||||
| 0.05 – 0.25 s | 3 – 15 | background + **the three blurred companions alone** |
|
||||
| 0.30 – 0.70 s | 18 – 42 | **all seven** — the crossfade |
|
||||
| 0.75 – 0.80 s | 45 – 48 | background + the three sharp logos |
|
||||
|
||||
Blurred first, then both, then sharp. The mechanism is reproduced. The claim
|
||||
that it was not came from describing the renderer instead of running it.
|
||||
|
||||
## Cross-check of the Decoder's quad mapping — ✅ survived, independently
|
||||
|
||||
`splash-quad-timeline.txt` names its quads by NDC rectangle off the guest's
|
||||
vertex stream. This export's declared rectangles, converted independently:
|
||||
|
||||
| | this export | the guest | agreement |
|
||||
|---|---|---|---|
|
||||
| `palogo_sqex` | x[−0.517, +0.523] y[−0.106, +0.083] | `Q0` x[−0.520, +0.520] y[−0.100, +0.080] | **~2 px** |
|
||||
| `palogo_sqex_eff` | x[−0.533, +0.539] y[−0.133, +0.114] | `Q7` x[−0.530, +0.540] y[−0.130, +0.120] | **~4 px** |
|
||||
|
||||
Two decoders, two paths — a `.pak` read statically and a vertex stream logged
|
||||
live — agreeing to a few pixels on both the sharp quad and the blurred one.
|
||||
That is corroboration of the mapping and of `Q7` being the companion.
|
||||
|
||||
## What is still open on the splash
|
||||
|
||||
* **The extent.** The rectangles agree; the *alphas* are where the 5-units-per-
|
||||
frame discrepancy above came from, and until that is settled it is not
|
||||
possible to say whether the game holds the blurred copy longer than we do.
|
||||
That is the same question as H3 and is asked once, there.
|
||||
* Whether `palogo_eff0` (kind `0x10`, a full-screen quad, like the title's
|
||||
`pteff00`) is the splash's fade veil. Not examined this iteration.

|
||||
|
||||
## The original page, kept for the arrival half
|
||||
|
||||
**Status:** ✅ **the "arrives late" observation does not reproduce as a timing
|
||||
error** — measured on the current build, and the plate's onset sits on its
|
||||
declared keyframe. 🔴 **A different divergence in the same element is real and
|
||||
was not being looked for: the port holds `PRESS Ⓐ` lit permanently, where the
|
||||
disc declares a 30-unit pulse.** Written 2026-09-02 by the Port at `6263686`.
|
||||
|
||||
`PLAYTEST-2026-09-02.md` asks for exactly this, in its own words: *"Worth
|
||||
re-asking now: the animation fix changed what the whole boot looks like, so the
|
||||
original observation may simply no longer reproduce."* And there is a specific
|
||||
reason to re-ask rather than assume — **the previous plate numbers were taken
|
||||
through the `pose_at` bug**, the same way the 0.01 % that manufactured H2's false
|
||||
green was.
|
||||
|
||||
## What the disc declares
|
||||
|
||||
`export/screens/title/press_start.json`, one element `ptbtn00`:
|
||||
|
||||
```
|
||||
0:0 214:0 236:255 238:255 244:0 rest [383,550], sprite 513x50
|
||||
```
|
||||
|
||||
Invisible until **214**, full at **236–238**, **gone by 244**. A 30-unit pulse.
|
||||
|
||||
## The instrument, and the two controls it went through first
|
||||
|
||||
Filmed a real boot (`--skip-at=1 --linger=8 --film-interval=0.05`), no `--time`,
|
||||
no pinning. Then **two attempts at isolating the plate failed before one worked**,
|
||||
which is the part worth keeping:
|
||||
|
||||
1. 🔴 **A rect around the plate.** Contaminated — the rect overlaps the developer
|
||||
splash earlier in the boot, so the onset detector fired on the wrong screen.
|
||||
2. 🔴 **A control band 55 px above the plate.** Still wrong. The title's
|
||||
background sweep **moves**, so a spatially displaced control samples it at a
|
||||
different phase and cannot cancel it. It showed a "rise" that was the sweep.
|
||||
3. ✅ **The plate sprite's own transparent holes.** Same rectangle, same rows,
|
||||
interleaved with the glyphs at pixel scale — 7 672 glyph pixels against 10 412
|
||||
hole pixels, both built from the sprite's alpha channel. A co-located
|
||||
background sample, so `glyph − hole` is the plate and nothing else.
|
||||
|
||||
⚠️ Control 2 is the same defect as everything else on this project: **an
|
||||
instrument that cannot see the thing it is measuring separately from the thing
|
||||
it is measuring against.** It produced a plausible curve. The tell was that the
|
||||
"plate" and the background rose together in phase.
|
||||
|
||||
## Result 1 — the arrival is correct
|
||||
|
||||
`glyph − hole`, dark baseline **0.003**:
|
||||
|
||||
| overlay units | 205 | **214** | **222** | 230 | **238** | 246 |
|
||||
|---|---|---|---|---|---|---|
|
||||
| plate | 0.005 | **0.005** | **0.222** | 0.434 | **0.586** | 0.601 |
|
||||
|
||||
**Flat through 213.9 and risen by 222.1.** The declared onset `t=214` sits inside
|
||||
that bracket, and the bracket is 8 units wide because that is the film's sampling
|
||||
interval, not a measurement of anything. By `t=238` the plate is at 88 % of its
|
||||
lit level, against a declared full alpha at 236.
|
||||
|
||||
**The plate is not late.** Whatever the human saw in the 2026-09-01 play-test,
|
||||
the port's own clock puts `ptbtn00` on its declared keyframe.
|
||||
|
||||
## Result 2 — 🔴 and it then stays lit forever
|
||||
|
||||
The declared ramp returns to **0 at t=244**. It does not:
|
||||
|
||||
| | |
|
||||
|---|---|
|
||||
| dark baseline, `t < 214` | **0.003** |
|
||||
| minimum at any point after `t = 250` | **0.587** (at `ou` 342) |
|
||||
| maximum after `t = 250` | **0.664** |
|
||||
| span measured | `ou` 6 → **1974** — **8.1 declared cycles** |
|
||||
|
||||
Over eight cycles of its own declared timeline the plate **never returns within
|
||||
88 % of dark**. The 11.6 % ripple that is there is *not* the plate: it is in
|
||||
phase with the hole channel, i.e. it is the title's background sweep leaking
|
||||
through the anti-aliased glyph edges.
|
||||
|
||||
### Why, and it is a failure mode this port already wrote down
|
||||
|
||||
`ptbtn00`'s `rest.t = 236` and its settle instant is `t=236` — **the peak of the
|
||||
pulse**. `holding` parks the element there, so the port shows a `PRESS Ⓐ` plate
|
||||
that lights once and stays on.
|
||||
|
||||
`plate-arrival-halves.md` names this exact class already, about a different
|
||||
element:
|
||||
|
||||
> *"It is still wrong for transients — `ptlogo_back2eff1` is a two-frame flash
|
||||
> (0 at t52, `0xff` at t54–56, 0 by t58) and its `rest.t = 54` is the flash
|
||||
> **peak**, so `rest()` leaves five of these burning at once."*
|
||||
|
||||
**The plate is an instance of the family that page predicted, and nobody had
|
||||
checked the plate itself** — because that page was written to *eliminate* `rest.t`
|
||||
as a cause of lateness, which it correctly did, and having eliminated it as the
|
||||
cause of *one* defect nobody asked what else it was doing.
|
||||
|
||||
## What I have NOT changed, and why
|
||||
|
||||
Nothing. The port still holds the plate.
|
||||
|
||||
Reading the disc's keyframes is mine; **whether the running game pulses its
|
||||
`PRESS Ⓐ` plate is not.** The keyframes describe a blink and blinking is what
|
||||
`PRESS START` prompts conventionally do, but "conventionally" is not evidence and
|
||||
this project has been burned by exactly that kind of inference. The change is
|
||||
**proposed, not made**, and the Decoder has been asked for the one fact that
|
||||
settles it: does the plate pulse in the guest, and with what period?
|
||||
|
||||
⚠️ **This is not a regression from the animation fix.** Before the fix `pose_at`
|
||||
*assigned* the settle instant, which parks the plate at `t=236` too. The plate
|
||||
has been held for as long as the port has drawn it; the fix neither caused this
|
||||
nor was supposed to.
|
||||
|
||||
## What this does not claim
|
||||
|
||||
* That finding 3 was wrong when it was made. It says the port measures on time
|
||||
**now**, on a build whose boot the fix visibly changed.
|
||||
* That holding is wrong. It says the port's picture and the disc's keyframes
|
||||
disagree, and names who can adjudicate.
|
||||
* Anything about the plate's **absolute** alpha or position. Onset timing and
|
||||
whether it extinguishes, only.

# ✅ The pulse is now MEASURED — and still not implemented
|
||||
|
||||
**2026-09-02.** This page established that the port holds `PRESS Ⓐ` permanently
|
||||
lit where the disc declares a 30-unit pulse, and closed by saying the port would
|
||||
not move until someone measured whether the guest pulses it. It has been
|
||||
measured, as a by-product of F6:
|
||||
|
||||
| | |
|
||||
|---|---|
|
||||
| element | **`ptbtn00f`** — the focus variant, not `ptbtn00` |
|
||||
| period | **120 title units**, from 60.0 frames over 16 consecutive cycles with **zero variance**, against a 600-frame sweep loop |
|
||||
| peak alpha | **80**, not 255 |
|
||||
| duty | drawn **51 of every 60** frames |
|
||||
|
||||
The period is phase-free: it is exactly 1/10 of the sweep's declared 600-unit
|
||||
loop, and 60 leaf units × the leaf/title rate of 0.5 gives the declared 120.
|
||||
|
||||
**Not implemented, and deliberately so.** The current focus is the title's
|
||||
animation timing (F5/F6), both now closed; the plate's blink is neither, and the
|
||||
human's standing note on the plate is that its *delay* is accepted. Picking this
|
||||
up is a decision for them, not a gap to fill quietly.
|
||||
|
||||
⚠️ Note for whoever does: the port draws the plate through `ptbtn00`, and the
|
||||
pulsing element is `ptbtn00f`, reached by `focus_link`. That is the same element
|
||||
whose absence from a declaration-order walk has now caused trouble twice.

# The port never reported its own frame rate — it does now, and it is 13–25 fps here
|
||||
|
||||
**Status:** ✅ **instrument added and measured.** ❌ **The candidate it raised for
|
||||
play-test finding 4 is DEAD — tested on real hardware, not argued away. See the
|
||||
final section.** The port's draw path never had a case to answer. Written 2026-09-01 by the Port at
|
||||
`977965e`; HANDOFF on this branch answers `9ca1eb5`.
|
||||
|
||||
## The gap this closes
|
||||
|
||||
[`TEMPORAL-VERIFICATION.md`](../agents/TEMPORAL-VERIFICATION.md) §1 is
|
||||
unambiguous: a capture that asked for one rate and delivered another *"is not a
|
||||
slow capture, it is a **different** capture"*, and an instrument that cannot
|
||||
report its own completeness may not be trusted.
|
||||
|
||||
That rule has been applied to `--film` (which I fixed for exactly this), to the
|
||||
Decoder's harnesses, and to the oracle. **It had never once been applied to the
|
||||
thing being shipped.** The port had no idea what rate it drew at and no way to
|
||||
say.
|
||||
|
||||
It matters here specifically, because the splashes are the current focus and the
|
||||
open complaint about them is that ours is *less pronounced* than the game's.
|
||||
**A fade drawn in 45 frames and the same fade drawn in 12 are different
|
||||
animations**, and nothing in this port could have told them apart.
|
||||
|
||||
## The instrument
|
||||
|
||||
`boot.gd` now counts frames per screen and prints at every boot transition, at
|
||||
the end of the boot, and at every menu arrival:
|
||||
|
||||
```
|
||||
publisher_logo: 107 frames in 4.29 s -- 25.0 fps achieved, uncapped, worst gap 108 ms
|
||||
```
|
||||
|
||||
`worst gap` sits beside the mean deliberately: a hitch is what reads as wrong. A
|
||||
screen averaging 55 fps with one 400 ms stall looks broken, and a mean hides that
|
||||
by construction.
|
||||
|
||||
🔴 **Its first version printed `-9223372036854775808 requested`.**
|
||||
`DisplayServer.screen_get_refresh_rate()` returns a *float* and is `-1.0` when
|
||||
the display cannot say — which Xvfb cannot — and `%d` on that underflows to
|
||||
`INT64_MIN`. A rate line whose own denominator is nonsense is worse than no rate
|
||||
line. It now names the cap or says `uncapped`.
|
||||
|
||||
## What it measures, in this container
|
||||
|
||||
Three boots, same command, nothing else running:
|
||||
|
||||
| screen | run 1 | run 2 | run 3 | worst gap |
|
||||
|---|---|---|---|---|
|
||||
| `publisher_logo` | 17.3 fps | 19.6 | 25.0 | 100–115 ms |
|
||||
| `developer_logos` | 16.7 | 21.9 | 22.8 | 103–138 ms |
|
||||
| `title` | 17.2 | 14.2 | 12.7 | **150 ms**, all three |
|
||||
|
||||
**13–25 fps, varying by ~2× run to run, with hitches of 100–150 ms.** The
|
||||
title's 150 ms is identical across all three runs, which looks like a one-off
|
||||
cost rather than load — the video player is torn down immediately before it.
|
||||
|
||||
### 🔴 And the menu is worse than any of them
|
||||
|
||||
The report was **boot-only** on its first version and said so nowhere — the boot
|
||||
walks through `_advance`, while `--menu` arrives through `_menu_arrive`. So the
|
||||
mode a human actually spends time in, and the one where a slow frame is *felt as
|
||||
input lag* rather than seen as a coarse fade, reported nothing. An instrument
|
||||
covering half the application while its own page claims "every boot" is exactly
|
||||
the shape this port keeps finding in other people's work. Fixed in the same
|
||||
commit:
|
||||
|
||||
```
|
||||
main_menu: 20 frames in 2.05 s -- 9.7 fps achieved, uncapped, worst gap 150 ms
|
||||
```
|
||||
|
||||
**9.7 fps.** The main menu is the heaviest screen in the port — five additive
|
||||
elements, five spinning focus rings, a full-screen background — and it is the one
|
||||
the play-test spent its time on. At 9.7 fps a press takes up to 103 ms to appear
|
||||
and a spinning ring advances in ~10 visible steps per revolution.
|
||||
|
||||
⚠️ **This is `llvmpipe` software rasterisation under Xvfb in a loaded container.
|
||||
It is not a measurement of the human's hardware and must not be quoted as one.**
|
||||
What it establishes is that the port *can* run this slowly and never said so.
|
||||
|
||||
## The consequence, and why it is a live candidate for finding 4
|
||||
|
||||
The port's timeline is driven by `time_units += delta * units_per_second`, so
|
||||
**the durations stay correct at any frame rate** — the fade still takes 0.75 s.
|
||||
What changes is how many distinct alphas that fade is *drawn* at:
|
||||
|
||||
| rendered at | steps in the 45-unit build-in | steps in the glow's 15-unit rise |
|
||||
|---|---|---|
|
||||
| **16.7 fps (measured)** | **12.5** | **4.2** |
|
||||
| **22.8 fps (measured)** | **17.1** | **5.7** |
|
||||
| 30 Hz | 22.5 | 7.5 |
|
||||
| 60 Hz | 45.0 | 15.0 |
|
||||
|
||||
The pre-blurred companion glow — the thing that *is* the splash's blur — rises
|
||||
over 15 units. **In this container it is drawn at four to six distinct alphas.**
|
||||
At 60 Hz it would be fifteen.
|
||||
|
||||
A soft crossfade rendered in four steps, inside a 750 ms animation carrying a
|
||||
100–150 ms hitch, is a plausible mechanism for *"close, but not quite right"* and
|
||||
for *"the game's is more pronounced"* — and it is the **first candidate for
|
||||
finding 4 that is not already dead.** Every other one is: the keyframes are
|
||||
vindicated against the vertex stream, the companion quads are drawn, the blend
|
||||
space matches, the settled pose scores 0.01 % against the capture, and there is
|
||||
no post-process pass to add.
|
||||
|
||||
🔴 **It is a candidate, not a cause.** It depends entirely on what the machine
|
||||
running the port manages, and I cannot measure the human's. **The line now
|
||||
prints on every boot**, so the next play-test answers it for free: if it says 60
|
||||
fps and the splash still looks wrong, this is dead too.
|
||||
|
||||
## What is NOT affected, and it was worth checking
|
||||
|
||||
**Every timing result this port has published stands.** They are all derived from
|
||||
`_elapsed`, which is `+= delta` — a sum of frame times, correct at any rate — and
|
||||
from `time_units`, which is the same sum scaled. So:
|
||||
|
||||
* the splash dwells (4.270 s and 3.527 s) are unaffected — measured across runs
|
||||
whose frame rates differed by 2×, and they agreed to ±0.03 s;
|
||||
* the plate's arrival, the shared-clock check and the film's own index are all
|
||||
`_elapsed`-based.
|
||||
|
||||
That is the reassuring half of the same design: the port is *correct* at 13 fps
|
||||
and merely *coarse*. Had the timeline been frame-counted, every number in this
|
||||
corpus would have been wrong by a factor that changed between runs — which is
|
||||
precisely the failure the Decoder found in the emulator's own rate and withdrew a
|
||||
finding over.
|
||||
|
||||
## What this does not claim
|
||||
|
||||
* That 13–25 fps is what a player sees. It is what this container manages.
|
||||
* That the port has a performance defect. Textures are cached at `load_screen`
|
||||
and not decoded per frame — that was checked and is not the cause.
|
||||
* That capping or vsyncing would help. It would not raise the rate here, and
|
||||
changing presentation behaviour on my own authority is not mine to do.

Written the iteration after the section above, because *"is 9.7 fps llvmpipe or
|
||||
something in our draw path"* was left open and it is not a question to leave open
|
||||
after publishing a candidate cause.
|
||||
|
||||
## Pre-registered (R2)
|
||||
|
||||
> If the rasteriser is the limit, a near-empty Godot scene in this same container
|
||||
> will also run at roughly 10–25 fps. If my draw path is the limit, it will run
|
||||
> far faster — take **>100 fps** as the discriminator.
|
||||
|
||||
Same container, same Xvfb, same 1280×720 viewport, same `[rendering]` settings,
|
||||
almost nothing drawn:
|
||||
|
||||
```
|
||||
FPSPROBE mode=empty: 651 frames in 4.03 s -- 161.6 fps, worst gap 54 ms
|
||||
```
|
||||
|
||||
**161.6 fps.** The engine loop, the viewport and the present path are not the
|
||||
limit, by a factor of sixteen over the menu.
|
||||
|
||||
## 🔴 And the first control was not a control
|
||||
|
||||
Its `fill` modes drew **untextured** `draw_rect`s while every element the port
|
||||
draws is a **texture**. A control that does not do what its subject does bounds
|
||||
nothing — and it showed: the port's splashes were achieving ~21 Mpx/s against
|
||||
that control's ~50, which read as the port being mysteriously slow and was really
|
||||
the control being mysteriously fast. Adding a matched textured mode:
|
||||
|
||||
| mode | full-screen quads | achieved |
|
||||
|---|---|---|
|
||||
| `empty` | 0 | **161.6 fps** |
|
||||
| `fill3` | 3, untextured | 31.5 |
|
||||
| **`tex3`** | **3, textured** | **23.9** |
|
||||
| `fill7` | 7, untextured | 12.7 |
|
||||
| **`tex7`** | **7, textured** | **11.2** |
|
||||
|
||||
## The port sits inside the bracket, ordered by large-quad count
|
||||
|
||||
| screen | full-screen-ish quads | measured | bracket |
|
||||
|---|---|---|---|
|
||||
| `publisher_logo` | 1 | 17.3–25.0 | ≈ `tex3` |
|
||||
| `developer_logos` | 1 | 16.7–22.8 | ≈ `tex3` |
|
||||
| `title` | 6 | 12.7–17.2 | between `tex3` and `tex7` |
|
||||
| **`main_menu`** | **5** | **9.7** | ≈ `tex7` (11.2) |
|
||||
|
||||
**Every screen lands between the two matched controls, in the order the quad
|
||||
count predicts.** The port is drawing large textured alpha quads on a software
|
||||
rasteriser at exactly the rate a software rasteriser draws large textured alpha
|
||||
quads.
|
||||
|
||||
⚠️ Note the control's own spread: `fill3` measured **18.0** on one run and
|
||||
**31.5** on another. The container's load swings by ~1.75×, so the absolute
|
||||
numbers here are noise-dominated and only the **ordering and the bracket** are
|
||||
load-invariant — which is what `TEMPORAL-VERIFICATION.md` §3 says to prefer, and
|
||||
the reason this conclusion rests on those rather than on any single figure.
|
||||
|
||||
## 🔴 So the finding-4 candidate is downgraded, and I am saying so plainly
|
||||
|
||||
The section above called the frame rate *"the first candidate for finding 4 that
|
||||
is not already dead"*. **That now looks wrong, and it was mine.**
|
||||
|
||||
The quantisation argument still holds — a fade drawn in four steps is not a fade
|
||||
drawn in fifteen — but it only bites at these frame rates, and these frame rates
|
||||
are a property of **software rasterisation in this container**. Five to seven
|
||||
full-screen quads at 720p is nothing to any GPU; on real hardware the port would
|
||||
hit vsync and the fade would get its full 45 steps.
|
||||
|
||||
So unless the human ran the port software-rendered, this is not what they saw,
|
||||
and **every candidate for play-test finding 4 is now dead or near-dead.** That is
|
||||
an honest dead end rather than a lead, and it is written as one: leaving a
|
||||
plausible-sounding cause standing when its own control has undercut it is exactly
|
||||
how *"close but not right"* got explained four different wrong ways.
|
||||
|
||||
**The one thing that would revive it costs the human nothing**: the rate line now
|
||||
prints on every boot. If their next run says 60 fps, this is finished.
|
||||
|
||||
## What the port does NOT need
|
||||
|
||||
* No draw-path optimisation. 161.6 fps empty says the loop is fine, and the
|
||||
screens sit on the fill curve exactly where their quad counts put them.
|
||||
* No texture caching work — already done at `load_screen`, checked last
|
||||
iteration.
|
||||
* No `max_fps` or vsync change. It would not raise the rate here, and it is a
|
||||
presentation decision rather than a defect.

# ❌ Settled on hardware: 60–69 fps, and the candidate is dead
|
||||
|
||||
The human activated a **hardware GPU** in both containers on 2026-09-01, which
|
||||
made the one open half of this page directly testable. Godot picks it up with no
|
||||
change on our side:
|
||||
|
||||
```
|
||||
Vulkan 1.4.312 - Forward+ - Using Device #0: NVIDIA - NVIDIA GeForce GTX 1070 Ti
|
||||
```
|
||||
|
||||
## Pre-registered (R2)
|
||||
|
||||
> Five to seven full-screen textured quads at 720p is trivial for that card. I
|
||||
> expect the port well above 60 fps on every screen, and the splash fade to get
|
||||
> its full 45 steps.
|
||||
|
||||
| screen | llvmpipe (before) | **GPU (after)** | worst gap |
|
||||
|---|---|---|---|
|
||||
| `publisher_logo` | 17.3–25.0 | **69.4** | 83 ms |
|
||||
| `developer_logos` | 16.7–22.8 | **69.1** | 15 ms |
|
||||
| `title` | 12.7–17.2 | **61.1** | 67 ms |
|
||||
| **`main_menu`** | **9.7** | **59.6** | 117 ms |
|
||||
|
||||
**A 3–6× jump, and every screen is now at or above 60 fps.** The prediction held.
|
||||
|
||||
## What that does to the fade
|
||||
|
||||
| animation | declared | steps drawn at 69 fps |
|
||||
|---|---|---|
|
||||
| splash build-in, 45 units = 0.750 s | 45 alphas | **52** |
|
||||
| companion glow's rise, 15 units = 0.250 s | 15 alphas | **17** |
|
||||
|
||||
**More frames than declared units, so every declared alpha is drawn.** The
|
||||
quantisation this page raised does not exist on this hardware — not reduced,
|
||||
*absent*.
|
||||
|
||||
## ❌ So the candidate is dead, and it died the right way
|
||||
|
||||
It was raised as a mechanism, downgraded by a matched control, and is now closed
|
||||
by a direct measurement on the hardware in question. **Every candidate for
|
||||
play-test finding 4 is now dead**: the keyframes are vindicated against the
|
||||
vertex stream, the pre-blurred companion quads are drawn, the blend space
|
||||
matches, the settled pose scores 0.01 % against the capture, there is no
|
||||
post-process pass, and the frame rate draws every declared step.
|
||||
|
||||
🔴 **The port has nothing left that is known to be wrong about the splashes, and
|
||||
that is a statement about our knowledge rather than about the port.** The human
|
||||
saw something. Nothing we can measure reproduces it.
|
||||
|
||||
**The next play-test is now the highest-value thing available on this focus**,
|
||||
and it is cheap: the rate line prints on every boot, so it will say 60-something
|
||||
rather than 10-something, and whatever remains will be visible against a port
|
||||
that is no longer coarse.
|
||||
|
||||
## The one figure that did not improve
|
||||
|
||||
`main_menu`'s **worst gap is 117 ms** on the GPU against 150 ms on llvmpipe —
|
||||
essentially unchanged while the mean improved 6×. A hitch that survives a 6× fill
|
||||
speed-up is not fill. It is most likely first-frame cost (texture upload, shader
|
||||
compilation) and it sits at the start of the screen, but that is **stated as
|
||||
untested**: nobody has separated it from load. It is small, it is once per
|
||||
screen, and it is recorded rather than chased.

# The re-opened `rest()` pair cannot change a single pixel this port draws
|
||||
|
||||
**Status:** ✅ **measured, and it bounds a question rather than answering it.**
|
||||
Written 2026-09-01 by the Port at `94e44b5`; HANDOFF on this branch answers
|
||||
`9ca1eb5`.
|
||||
|
||||
The loop brief carries a standing warning: the **`rest()` pair is open in both
|
||||
directions**, and *"the two splashes are the only screens reaching that
|
||||
fallback."* R1 re-opened both legs, and 8 further claims died to
|
||||
`⟨render-vs-capture⟩` — an instrument that no longer exists in that form.
|
||||
|
||||
`ScreenView.settle_time()` uses `rest.t`, so this port has been sitting on a
|
||||
question with no instrument behind either leg. **It turns out not to matter, and
|
||||
that is worth establishing rather than waiting on.**
|
||||
|
||||
## What reaches the fallback
|
||||
|
||||
`Element::rest()` takes the longest **plateau** — a run of consecutive identical
|
||||
keyframes — and falls back to the longest dwell when there is none. So an element
|
||||
reaches the fallback exactly when no two consecutive keyframes are identical.
|
||||
|
||||
Census over all sixteen exported screens, at every nesting depth:
|
||||
|
||||
| screen | elements reaching the fallback |
|
||||
|---|---|
|
||||
| `publisher_logo` (and `_r`) | `palogo_sqex_eff` |
|
||||
| `developer_logos` (and `_r`) | `palogo_anima_eff` |
|
||||
| **`title_jp`** | **`ptlogo_eff3`** |
|
||||
|
||||
**Five elements in the whole export**, and only three distinct ones.
|
||||
|
||||
## 🔴 The brief's claim is narrowly refuted
|
||||
|
||||
*"The two splashes are the **only** screens reaching that fallback"* — `title_jp`
|
||||
reaches it too, through `ptlogo_eff3`.
|
||||
|
||||
⚠️ Stated as a measurement of the **current** export and nothing more. That
|
||||
sentence may have been true when written: the record-layout fix re-timed
|
||||
keyframes across the corpus, and a plateau is exactly the kind of thing it could
|
||||
create or destroy. This does not say the claim was wrong when made; it says it is
|
||||
not true now.
|
||||
|
||||
## And every one of them is invisible where it is read
|
||||
|
||||
The fallback only matters if the element it picks a pose for is actually drawn.
|
||||
Asked of the port directly, at each screen's own settled instant:
|
||||
|
||||
```
|
||||
publisher_logo t=140 drew 2 not drawn: palogo_sqex_eff (transparent at t=140)
|
||||
developer_logos t=117 drew 4 not drawn: palogo_anima_eff (transparent at t=117)
|
||||
title_jp --pose=rest drew 23 not drawn: ptlogo_eff3 (transparent at rest)
|
||||
```
|
||||
|
||||
**Every element that reaches the `rest()` fallback is fully transparent at the
|
||||
instant anything reads its rest pose.**
|
||||
|
||||
> So no `rest()` rule — the current plateau-plus-dwell, `last`, `maxalpha` or
|
||||
> `lastall` — can change any pixel this port draws. The pair is open, and for the
|
||||
> port it is **moot**.
|
||||
|
||||
That is why the splash rows score 0.01 % against their captures while resting on
|
||||
a heuristic nobody can currently defend: the heuristic is not load-bearing there.
|
||||
|
||||
## Why this was worth an iteration rather than a wait
|
||||
|
||||
The three elements are the **pre-blurred companion glows** and one title sparkle
|
||||
— transients that exist to be seen briefly and then leave. An element with no
|
||||
plateau is, almost by definition, one that never holds still, and a screen's
|
||||
settled instant is chosen to be where things are holding still. The two
|
||||
conditions are close to mutually exclusive, which is why the intersection is
|
||||
empty and why it was worth checking rather than assuming either way.
|
||||
|
||||
⚠️ **This does not rehabilitate `rest.t`.** It is still the wrong answer for
|
||||
transients — `ptlogo_back2eff1` is a two-frame flash whose `rest.t = 54` is the
|
||||
flash *peak*, and `rest()` would leave five of those burning at once on the
|
||||
title. That is a **plateau** case, not a fallback case, and it is untouched by
|
||||
anything here.
|
||||
|
||||
## What this does not claim
|
||||
|
||||
* That the `rest()` pair is settled. It is open, and this page does not touch it.
|
||||
* That `rest.t` is right. `settle_time()` still takes the maximum over elements,
|
||||
and what that means for *when the boot advances* is a separate question — a
|
||||
screen still plays to `exit_time()` afterwards, so the dwell is governed by
|
||||
that, not by `rest.t`. **Measured for the drawn picture; argued for the dwell.**
|
||||
* Anything about the other 7 claims R1 re-opened against
|
||||
`⟨render-vs-capture⟩`. Not mine to re-derive.

# The splash: frozen, then fixed, and now checked for SHAPE as well as motion
|
||||
|
||||
**Status:** ✅ **animates, and the ramp matches the declared curve.** Written
|
||||
2026-09-02 by the Port; HANDOFF on this branch answers `9ca1eb5`.
|
||||
|
||||
The 2026-09-02 play-test found the splash frozen. The cause and the fix are in
|
||||
the commit history; this page is the part that comes after — **is the animation
|
||||
now the right animation?** `motion-census` says explicitly that it cannot answer
|
||||
that: *"a wrong ramp that moves every frame passes here."*
|
||||
|
||||
## Pre-registered (R2)
|
||||
|
||||
`palogo_sqex_eff` declares `0:a=0 → 15:a=255 → 30:a=212 → 45:a=0` — three
|
||||
segments, three gradients:
|
||||
|
||||
| segment | declared |
|
||||
|---|---|
|
||||
| 0 → 15 | **+17.0** per unit |
|
||||
| 15 → 30 | **−2.87** per unit |
|
||||
| 30 → 45 | **−14.13** per unit |
|

|
||||
> **30**, the middle slope about **1/5** the magnitude of the last, and the rise
|
||||
> about **1.2×** the last.
|
||||
|
||||
## Measured, from a film of a real boot
|
||||
|
||||
Region: `686x11+299+319` — the companion's top strip, which **no other element
|
||||
overlaps**, so the number is that element's own alpha and not a composite.
|
||||
|
||||

||||
| 19.21 | 0.07260 | **−0.00087** |
|
||||
| 25.38 | 0.06695 | **−0.00092** |
|
||||
| 28.39 | 0.06482 | −0.00071 |

|
||||

|
||||
| 46.39 | 0.00000 | gone |
|
||||
|
||||
**Breakpoints land where declared**: the rise stops between 13.0 and 16.1, the
|
||||
gentle fall steepens between 28.4 and 31.4.
|
||||
|
||||
| ratio | declared | measured |
|
||||
|---|---|---|
|
||||
| middle : last | 0.203 | **0.213** |
|
||||
| rise : last | 1.20 | **1.20** |
|
||||
|
||||
Within 5 % and exact respectively. **The port interpolates piecewise-linearly
|
||||
across the declared segments** — which is what the Decoder independently measured
|
||||
the game doing (28 distinct alphas over 28 consecutive presents, modal steps −3
|
||||
and −14 against predicted −2.87 and −14.13).
|
||||
|
||||
⚠️ **Ratios, not absolutes, and deliberately.** The strip mean is an alpha
|
||||
scaled by whatever the sprite's own pixels are; its absolute value carries the
|
||||
texture. A ratio between segments divides that out, which is why the shape is
|
||||
checkable from a composite at all. Anyone quoting 0.00515 as an alpha is
|
||||
misreading it.
|
||||
|
||||
## What this still does not establish
|
||||
|
||||
* That it **looks** right. Three instruments have now agreed with a picture a
|
||||
human called wrong, and the fourth agreeing does not change the standing of
|
||||
the fifth. A play-test is the check.
|
||||
* ~~Anything about the **developer** splash's three logo/companion pairs. One
|
||||
element, one screen.~~ ✅ **Closed below, and the developer splash turned out to
|
||||
be the far better test.**
|
||||
* The **absolute** alpha. The shape matches; whether the port's alpha equals the
|
||||
game's at a given unit is `verify-capture`'s question, and it answers 0.01 %
|
||||
at the settled pose only.
|
||||
|
||||

|

# ✅ The developer splash: three elements, TWO declared shapes, on one screen
|
||||
|
||||
The publisher check above had a structural weakness I named at the time: one
|
||||
element, one screen, one shape. If the port applied *some* single ramp to
|
||||
everything, that check would pass.
|
||||
|
||||
**The developer splash cannot be fooled that way, because it declares two
|
||||
different shapes at once:**
|
||||
|
||||
| element | declared alpha | middle segment |
|
||||
|---|---|---|
|
||||
| `palogo_gamearts_eff` | `0:0 15:255 30:255 45:0` | **flat** |
|
||||
| `palogo_seta_eff` | `0:0 15:255 30:255 45:0` | **flat** |
|
||||
| `palogo_anima_eff` | `0:0 15:255 30:212 45:0` | **decays 17 %** |
|
||||
|
||||
Same screen, same frames, same clock, same code path. The two flat elements are
|
||||
the control for the one that is not — no second run, no second renderer, and
|
||||
nothing for a phase or rate error to hide behind, because any such error hits all
|
||||
three identically.
|
||||
|
||||
## Pre-registered, before the film was read
|
||||
|
||||
> In units 15→30, `gamearts` and `seta` hold flat while `anima` falls gently.
|
||||
> All three fall steeply 30→45.
|
||||
|
||||
## Measured, off a real filmed boot
|
||||
|
||||
Companion-only strips (each companion's rectangle minus the logo sitting inside
|
||||
it), mean luma, `--film-interval=0.03`:
|
||||
|
||||
```
|
||||
segment units 16-29 units 31-44
|
||||
gamearts +0.00000 -0.00101
|
||||
seta +0.00000 -0.00151
|
||||
anima -0.00001 -0.00003
|
||||
```
|
||||
|
||||
**The two flat ones are flat to five decimals. The decaying one decays.** And all
|
||||
three fall over 31–44, so the flatness is not a dead element.
|
||||
|
||||
## The quantitative version, and the falsification arm
|
||||
|
||||
Each trace normalised by a **single solved gain** — one scalar per element, not a
|
||||
per-point fit — against the declared curve, over the whole `t=0..45` ramp:
|
||||
|
||||
| element | fitted against | max err | rms err |
|
||||
|---|---|---|---|
|
||||
| `gamearts` | **its own (flat)** | **0.49 %** | 0.23 % |
|
||||
| `seta` | **its own (flat)** | **0.50 %** | 0.27 % |
|
||||
| `anima` | **its own (decay)** | **2.18 %** | 1.19 % |
|
||||
| `gamearts` | anima's decay | 8.32 % | 4.80 % |
|
||||
| `seta` | anima's decay | 8.08 % | 4.86 % |
|
||||
| `anima` | flat | 8.82 % | 4.94 % |
|
||||
|
||||
**Both directions.** Every element fits its own declared shape 4–17× better than
|
||||
it fits the other one available on the same screen. A port that drew one ramp for
|
||||
all three would sit at ~8 % on at least one row; none does.
|
||||
|
||||
`anima`'s 2.18 % is the loosest row and the reason is its signal: its
|
||||
companion-only strip means ~0.0005 against gamearts's ~0.015, thirty times
|
||||
dimmer, so its noise floor is thirty times higher in these units. It still
|
||||
separates from the wrong curve by 4×.
|
||||
|
||||
## What this adds over the publisher check
|
||||
|
||||
The publisher check established that the ramp has the declared *breakpoints and
|
||||
slope ratios*. This establishes that the ramp is **per-element** — that the port
|
||||
reads each element's own keyframes rather than applying a screen-wide curve. That
|
||||
is a different failure mode, and it is the one that would have survived the
|
||||
publisher check unnoticed.
|
||||
|
||||
## What it still does not establish
|
||||
|
||||
* That it **looks** right. This is instrument five. The standing of a human's
|
||||
eyes is unchanged by it.
|
||||
* The **absolute** alpha, for the same reason as above — a solved gain is
|
||||
deliberately scale-free, so this is a shape result and says nothing about
|
||||
whether the port's alpha equals the game's at a given unit.
|
||||
* Anything about the **logo** elements. Both checks measure the pre-blurred
|
||||
*companions*, because those are the strips that can be isolated from the sharp
|
||||
logo underneath them.

# The proposed splash rate contradicts the splash dwells — NOT adopted
|
||||
|
||||
**Status:** ✅ **RESOLVED — the rate was withdrawn.** The Decoder withdrew it the
|
||||
same day (`splash-rate-withdrawn.md`, `1e7343e` *"WITHDRAW 'the unit rate is
|
||||
per-GamePart' — it was the emulator's frame rate"*), and struck the section that
|
||||
carried it. §1 of `splash-declared-vs-captured.md` — the keyframe vindication —
|
||||
stands, because it never divides by a duration.
|
||||
|
||||
**The port never moved, so nothing has to be undone.** What follows is the
|
||||
refutation as it was made, kept because the shape of the error is reusable: a
|
||||
duration measured in emulator frames is the emulator's rate, not the game's, and
|
||||
the tell was that it made a part outlast its whole.
|
||||
|
||||
---
|
||||
|
||||
**Original status:** 🔴 **refutation attempt, and it lands.** Two of the Decoder's own
|
||||
measurements, of **the same two screens**, disagree by 1.7×. The port has **not**
|
||||
changed `keyframe_units_per_second` and is still at 60. Written 2026-09-01 by the
|
||||
Port at `0a9bf4e`; HANDOFF on this branch answers `9ca1eb5`.
|
||||
|
||||
## What was proposed
|
||||
|
||||
`docs/re/splash-declared-vs-captured.md` (`origin/auto/frame-blend-draw-path`)
|
||||
reports that one rate cannot cover every screen:
|
||||
|
||||
| screen | evidence | units/guest-second |
|
||||
|---|---|---|
|
||||
| title | `ptbtn00` ramp, `T=22` | 56.8 |
|
||||
| splash | `palogo_gamearts` ramp, `T=15` | 39.1 |
|
||||
| splash | **160-unit hold in 4.514 guest s** | **35.4** |
|
||||
|
||||
with the conclusion that *"a splash played at 60 units/s runs 1.5–1.7× too
|
||||
fast"*, and a recommendation to use ~35–40 for the splashes. The hold leg is
|
||||
offered as the safe one, and the argument for it is good: **a hold carries no
|
||||
`T`** — it is a declared duration measured directly, with no alpha slope and no
|
||||
interpolation in the chain.
|
||||
|
||||
## Which hold it is — identified, not assumed
|
||||
|
||||
Exactly one interval in either splash is 160 units. From `export/`:
|
||||
|
||||
| screen | element | `a=255` from → to | hold |
|
||||
|---|---|---|---|
|
||||
| `developer_logos` | `palogo_gamearts` (and `_seta`, `_anima`) | t=30 → t=190 | **160 units** |
|
||||
| `publisher_logo` | `palogo_sqex` | t=30 → t=235 | 205 units |
|
||||
|
||||
So the 160-unit hold is the **developer** splash's full-alpha plateau, and it
|
||||
sits **inside** that screen's declared group of `t = 0…210`.
|
||||
|
||||
## The contradiction
|
||||
|
||||
`authored/timing.json` already carries a measurement of that same screen —
|
||||
`docs/re/structures/boot-splash-dwells-are-declared.md`, the Decoder's, over
|
||||
**three cold boots**:
|
||||
|
||||
```
|
||||
publisher declared t=0..255 corpus 4.30 / 4.60 / 4.37 s
|
||||
developer declared t=0..210 corpus 3.51 / 3.50 / 3.37 s
|
||||
```
|
||||
|
||||
🔴 **The 160-unit hold is measured at 4.514 s. The 210-unit group that contains
|
||||
it is measured at 3.37–3.51 s. A sub-interval cannot outlast the interval
|
||||
containing it.**
|
||||
|
||||
That is not two methods disagreeing about a rate. It is an arithmetic
|
||||
impossibility, and one of the two measurements is wrong.
|
||||
|
||||
| | implied units/s |
|
||||
|---|---|
|
||||
| developer whole group, 210 units in 3.46 s (3 boots) | **60.7** |
|
||||
| publisher whole group, 255 units in 4.42 s (3 boots) | **57.7** |
|
||||
| developer 160-unit hold in 4.514 s (1 run) | 35.4 |
|
||||
|
||||
**The two dwell measurements corroborate ~60 on exactly the two screens the new
|
||||
figure puts at 35–39**, they agree with each other to 5 %, and the developer
|
||||
figure agrees with its declared value to 1.1 % — two of its three runs to 0.3 %.
|
||||
|
||||
At 35.4 units/s the declared groups would run **5.93 s** and **7.20 s**, against
|
||||
corpus dwells of 3.37–3.51 and 4.30–4.60. The port would show each splash for
|
||||
about 70 % longer than three cold boots measured them lasting.
|
||||
|
||||
## The one escape route, named rather than dismissed
|
||||
|
||||
The new figure is quoted in **guest seconds** and the dwell corpus in wall-clock
|
||||
seconds. If those clocks differ by 1.7× the two are not comparable and there is
|
||||
no contradiction.
|
||||
|
||||
**It does not look like the answer.** The known gap between the two is Canary
|
||||
presenting at ~28.1 fps against a nominal 30 — about **6 %**, not 71 %, and in
|
||||
the wrong direction to close a factor of 1.7. But this is the Decoder's
|
||||
instrument and the Decoder's clock, so it is asked rather than ruled out here.
|
||||
|
||||
## What the port did
|
||||
|
||||
**Nothing.** `keyframe_units_per_second` stays at **60**, one value, for every
|
||||
screen.
|
||||
|
||||
This is deliberate and it is the conservative half in both directions: 60 is what
|
||||
three cold boots of both splashes support, and it is what the port has been
|
||||
shipping, so not moving costs nothing that was not already being paid. Adopting
|
||||
35.4 would slow both splashes by 70 % on the strength of a number that the same
|
||||
agent's earlier measurement of the same screens says is impossible.
|
||||
|
||||
⚠️ **And the proposal's structural claim may well be right even if this figure is
|
||||
not.** *"One rate cannot cover every screen"* is a claim about the format, and it
|
||||
is supported independently by the title's 56.8 sitting 5 % off the splashes'
|
||||
~58–61. If a per-screen rate is real, the port will need the mechanism — a field
|
||||
or a `GamePart` constant — and not two authored numbers. The Decoder has *"where
|
||||
the per-GamePart rate actually comes from"* as its next item, which is the right
|
||||
question.
|
||||
|
||||
## What this does not claim
|
||||
|
||||
* That the title's 56.8 is wrong. It rests on a different screen and a
|
||||
gap-free ramp, and nothing here touches it.
|
||||
* That the splash **keyframes** are wrong. They are now vindicated — see below.
|
||||
* That the dwell corpus is right and the new capture wrong. Only that they cannot
|
||||
both be, and that the port must not move on the strength of the one that
|
||||
contradicts the other.
|
||||
|
||||
## ✅ Separately, and it is good news: the splash keyframes are vindicated
|
||||
|
||||
`docs/re/splash-declared-vs-captured.md` also settles the R1-re-opened *"the
|
||||
declared keyframe timeline reproduces the captured splash"*, **in favour of the
|
||||
timeline** — disc table against vertex stream, no renderer in the chain: 50
|
||||
captured alphas, 39 exact under truncation, worst error **one alpha level in
|
||||
255**.
|
||||
|
||||
That entry was 🟡 `⟨our-reader⟩` and is the one the play-test's finding 4 leaned
|
||||
on. **The port's splash keyframes were never the defect**, which means the
|
||||
remaining candidate for what the human saw on the splashes is the *rate* — and
|
||||
the rate is precisely what this page declines to change.
|
||||
|
||||
|
||||
---
|
||||
|
||||
# ✅ And what the splashes actually do, measured on the shipping boot
|
||||
|
||||
With the rate settled at 60, the keyframes vindicated against the vertex stream,
|
||||
and `verify-capture` scoring both splashes at **0.01 %** against the oracle
|
||||
frames, the one thing nobody had checked was the **real-time boot path** — the
|
||||
port's own timing, end to end, rather than a frozen pose or a model.
|
||||
|
||||
## Pre-registered (R2)
|
||||
|
||||
> At 60 units/s, `publisher_logo` holds for 255 + 9 = **264 units = 4.400 s** and
|
||||
> `developer_logos` for 210 + 9 = **219 units = 3.650 s** — the figures
|
||||
> `authored/timing.json` states the port emits. Accept ±0.10 s.
|
||||
|
||||
Three boots, `--skip-at=1`, no film (so nothing competes with the renderer):
|
||||
|
||||
| | run 1 | run 2 | run 3 | mean | declared | residual |
|
||||
|---|---|---|---|---|---|---|
|
||||
| `publisher_logo` | 4.28 | 4.26 | 4.27 | **4.270 s** | 255 u = 4.250 s | **+1.2 units** |
|
||||
| `developer_logos` | 3.50 | 3.57 | 3.51 | **3.527 s** | 210 u = 3.500 s | **+1.6 units** |
|
||||
|
||||
**The prediction failed, by 0.130 s and 0.123 s — and the port was right.**
|
||||
|
||||
## 🔴 The failure was in the claim, not the code
|
||||
|
||||
`authored/timing.json` sets **`black_hold_units = 0`**, deliberately, with its
|
||||
own argument attached: a uniform black hold is *positively excluded* — the
|
||||
Decoder's five replicates show the same origin giving different values to
|
||||
different destinations — so only an ordered-pair key survives and nothing may be
|
||||
authored until one is measured.
|
||||
|
||||
So there is no 9-unit hold to add, and the port has never added one. Yet two
|
||||
places asserted it did:
|
||||
|
||||
* `authored/timing.json`, `dwell_why`: *"The port emits 4.400 s and 3.650 s —
|
||||
each declared value plus the 9-unit black hold, exactly. So the pacing was
|
||||
right all along and nothing changes in the code."*
|
||||
* `port/scripts/boot.gd`, in the `_advance` block: the same sentence.
|
||||
|
||||
**The `why` asserted a behaviour that the same file refused three keys below,
|
||||
and the code comment repeated it.** Both are corrected in place. Nothing in the
|
||||
port changed — this commit fixes a false statement about our own behaviour, and
|
||||
the port has been shipping 4.270 / 3.527 since P3.
|
||||
|
||||
## What it does not settle
|
||||
|
||||
Against the corpus dwells (means **4.42** and **3.46** s) neither figure
|
||||
dominates: the port is 3.4 % short on the publisher and 2.0 % long on the
|
||||
developer, where the claimed values would be 0.5 % short and 5.5 % long. **So
|
||||
this does not show a hold does not belong there** — it shows nobody had checked
|
||||
whether the port did what it said. `black_hold_why`'s ordered-pair ask stands
|
||||
unchanged.
|
||||
|
||||
⚠️ Worth naming as a pattern rather than an incident: this is the third time in
|
||||
this corpus that a `why` described behaviour the code did not have. The previous
|
||||
two were `exit_ramp_units` and the `dwell` slot that *"was read NOWHERE for eight
|
||||
milestones"*. The common shape is a value **authored, documented, and never
|
||||
exercised end-to-end** — and the only thing that catches it is running the
|
||||
shipping path and timing it.

# If 120 units/s is right, the switch is one constant — audited, and pre-registered
|
||||
|
||||
**Status:** ✅ **SETTLED by a designed experiment.** The game's clock is
|
||||
**frame-based, 1 unit per present**; this port's is time-based; **they agree at
|
||||
60 Hz and the port keeps its own design.** 120 is withdrawn by its author. The
|
||||
port never moved, so nothing has to be undone.
|
||||
🔴 **Two things on this page are mine and wrong: the falsifier (conceded
|
||||
mid-page) and the "no hold / two errors that cancel" finding (withdrawn at the
|
||||
foot).** Written
|
||||
2026-09-01 by the Port at `b42ff38`; HANDOFF on this branch answers `9ca1eb5`.
|
||||
|
||||
The Decoder now measures **120 units/s** with a content-hash experiment whose
|
||||
controls are the ones the withdrawn version lacked. **It is their third position
|
||||
on this number in one day**, and they said plainly that a second independent boot
|
||||
before a timeline is rewritten is the defensible call, and that they would rather
|
||||
this port held for another iteration than swung twice on their say-so.
|
||||
|
||||
**Agreed, and the port has not moved.** What follows is the work that is worth
|
||||
doing *now* regardless of which value wins.
|
||||
|
||||
## Why hold
|
||||
|
||||
1. **Three positions in a day**, two of them already withdrawn by their author.
|
||||
2. **Reach is one boot.** They say so.
|
||||
3. They do **not** offer the 2.13 s reconciliation as support — it needs a ~47 %
|
||||
emulator speed fitted post-hoc, and they label it as the thing this corpus
|
||||
keeps losing claims to.
|
||||
4. Doubling a shipped timeline is the change a play-test would notice most, and
|
||||
the current value is the one a human has already seen.
|
||||
|
||||
None of that is an argument that 60 is right. **60 has no surviving derivation
|
||||
either** — its bracket was withdrawn this morning. Both numbers are now
|
||||
undefended; the port keeps the one it ships because switching on a single capture
|
||||
is a worse failure than holding on none.
|
||||
|
||||
## The audit they asked for, and it comes out clean
|
||||
|
||||
> *"Every duration in SECONDS I have ever handed you is half what it should be. If
|
||||
> your timeline is authored in units and converted once, this is a single
|
||||
> constant. If seconds are baked in anywhere, they all move."*
|
||||
|
||||
Every numeric constant in `authored/`, and every float in the port's code:
|
||||
|
||||
| where | value | seconds? | moves with the constant? |
|
||||
|---|---|---|---|
|
||||
| `timing.json` `keyframe_units_per_second` | 60 | — | **it IS the constant** |
|
||||
| `timing.json` `black_hold_units` | 0 | no — **units** | ✅ derived |
|
||||
| `timing.json` `dwell_seconds` | `null` | n/a | — |
|
||||
| `flow.json` `dwell` | prose only, "NOT SET" | n/a | — |
|
||||
| `audio.json` `loop_start_s` / `loop_end_s` | 9.44 / 61.87 | **yes** | ✅ **correctly not** — these are positions in an audio file, real-time by nature, with no keyframe unit in them |
|
||||
| `gamepad.gd` `ENTER` / `RELEASE` | 0.61 / 0.4 | no — deflection | — |
|
||||
|
||||
**No seconds are baked into the timeline anywhere.** Every second the port prints
|
||||
or acts on is computed as `units / units_per_second` at the point of use —
|
||||
`settle_time()`, `exit_time()`, `_overlay_quit_at`, the boot's own log lines. The
|
||||
switch is one number in one file.
|
||||
|
||||
## 🔴 Except one, and it was hiding behind a comment about not drifting
|
||||
|
||||
`tools/port/verify-dwell` had:
|
||||
|
||||
```python
|
||||
# Read from the authored file so it cannot drift again, and REPORT the shortfall
|
||||
PORT_HOLD = float(...get("black_hold_units", 0)) / 60.0
|
||||
```
|
||||
|
||||
**The value was read from the file. The rate was a literal.** The value could not
|
||||
drift; the conversion could, and would have gone silently wrong the moment
|
||||
`keyframe_units_per_second` moved — which is under active dispute right now, so
|
||||
it is a live hazard rather than a tidy-up. Harmless only because the hold is
|
||||
currently 0.
|
||||
|
||||
Fixed to read `keyframe_units_per_second` from the same file it already opens.
|
||||
|
||||
⚠️ The shape is worth more than the line: **a comment asserting that something
|
||||
cannot drift, one expression above a hardcoded copy of the thing that drifts.**
|
||||
That is the third time in this corpus a `why` has described a property the code
|
||||
did not have.
|
||||
|
||||
## Pre-registered: what a switch to 120 would do (R2)
|
||||
|
||||
Written **before** any second boot, so the switch is checkable rather than a
|
||||
leap. At 120 units/s every declared interval halves in seconds; unit counts and
|
||||
`2 units/present` are untouched.
|
||||
|
||||
| | declared | at 60 (shipping) | **at 120** |
|
||||
|---|---|---|---|
|
||||
| `PRESS Ⓐ` plate, full | t=236 | 3.933 s | **1.967 s** |
|
||||
| plate ramp onset | t=214 | 3.567 s | **1.783 s** |
|
||||
| publisher splash group | 255 units | 4.250 s | **2.125 s** |
|
||||
| developer splash group | 210 units | 3.500 s | **1.750 s** |
|
||||
| title build-in end | t=118 | 1.967 s | **0.983 s** |
|
||||
| `ptcopyright` full | t=160 | 2.667 s | **1.333 s** |
|
||||
|
||||
**The falsifier is the splash dwells.** Three cold boots measured the publisher
|
||||
at 4.30 / 4.60 / 4.37 s and the developer at 3.51 / 3.50 / 3.37 s. At 120 the
|
||||
port would show them for **2.13 s** and **1.75 s** — roughly half what those
|
||||
boots recorded.
|
||||
|
||||
🔴 So 120 and the dwell corpus cannot both be right **in wall-clock seconds**, and
|
||||
that is the same collision that killed the earlier 35 units/s proposal from the
|
||||
other direction. Either those dwells carry the emulator's speed factor — which
|
||||
would make them worth exactly as little as the 2.13 s route the Decoder has
|
||||
already declined to lean on — or 120 is wrong. **Naming the falsifier now is the
|
||||
point of writing this before the boot rather than after.**
|
||||
|
||||
## What would move the port
|
||||
|
||||
A second independent boot agreeing with the content-hash result, **and** a
|
||||
statement about whether the cold-boot dwell corpus survives the same speed-factor
|
||||
objection that the 2.13 s route does not. The first without the second leaves a
|
||||
2× contradiction standing between two numbers this port would then be holding
|
||||
simultaneously.
|
||||
|
||||
|
||||
---
|
||||
|
||||
# 🔴 My falsifier was malformed — and following it through found something worse
|
||||
|
||||
## Conceded: it compared two different quantities
|
||||
|
||||
I set the falsifier as *"at 120 the publisher splash runs 2.125 s, against three
|
||||
cold boots measuring 4.30/4.60/4.37"*. **2.125 s is the declared *animation*
|
||||
length. 4.3 s is how long the *screen* is up.** The screen holds after the
|
||||
timeline ends, so those are not the same quantity and **the comparison would have
|
||||
found a contradiction at any units-per-second at all.**
|
||||
|
||||
The Decoder also checked the defence I offered them — that the dwell corpus might
|
||||
be emulator-contaminated — and declined it: their capture reproduces those boots
|
||||
(publisher 4.263 s, developer 3.457 s, four runs agreeing). **They could have
|
||||
waved my numbers away and did not.**
|
||||
|
||||
## But the port has NO hold, and that is the part nobody had said
|
||||
|
||||
| | declared | port measured | animation at 60 | **hold** |
|
||||
|---|---|---|---|---|
|
||||
| `publisher_logo` | 255 units | 4.270 s | 4.250 s | **+0.020 s** |
|
||||
| `developer_logos` | 210 units | 3.527 s | 3.500 s | **+0.027 s** |
|
||||
|
||||
**The port's screen time *is* its animation time.** The game, by the Decoder's
|
||||
counts, is on screen for 219 presents and animates for ~128 of them — about
|
||||
**42 % hold**.
|
||||
|
||||
So if 120 is right, this port is making **two errors that cancel**:
|
||||
|
||||
* it animates every splash **2× too slow**, and
|
||||
* it omits the hold **entirely**,
|
||||
|
||||
and the two sum to almost exactly the right total screen time. That is why the
|
||||
dwell check has been passing, and **`authored/timing.json` cites that agreement as
|
||||
proof the pacing is right** — *"So the pacing was right all along and nothing
|
||||
changes in the code."* Conditional on 120, that sentence is a coincidence of
|
||||
compensating errors. Corrected in place.
|
||||
|
||||
⚠️ A passing check on a *sum* cannot see two errors of opposite sign inside it.
|
||||
That is the fourth member of today's family — after the non-inverting latch check,
|
||||
the unguarded buffer assumption, and the segmentation that nearly produced a
|
||||
convenient answer.
|
||||
|
||||
## 🔴 And 120 explains both open play-test findings. 60 explains neither.
|
||||
|
||||
This is not a measurement and it is not mine to call decisive. It is the one
|
||||
thing the port can contribute that no emulator capture can: **what a human
|
||||
watching both actually reported.**
|
||||
|
||||
| | at 60 (shipping) | at 120 |
|
||||
|---|---|---|
|
||||
| **finding 3** — *"the plate arrives late"* | full at **3.933 s** | **1.967 s** |
|
||||
| **finding 4** — *"the game's fade is more pronounced"* | build-in **0.750 s**, then the screen leaves at once | build-in **0.375 s**, then the screen **holds ~1.7 s** |
|
||||
|
||||
At 60 the port's logo drifts in slowly and leaves immediately. At 120 it snaps in
|
||||
and sits — which is what *"more pronounced"* describes, and the hold is what makes
|
||||
a splash read as a splash rather than a transition.
|
||||
|
||||
**Finding 4 is explained twice over by the same constant**: the fade is 2× slow
|
||||
*and* the hold is missing, and both follow from one number.
|
||||
|
||||
Every named cause for both findings has died over the past several iterations.
|
||||
**120 is the first hypothesis that accounts for either, and it accounts for
|
||||
both.**
|
||||
|
||||
## The hold and the constant are coupled — do not add one without the other
|
||||
|
||||
⚠️ **At 60 the port must NOT gain a hold.** The animation already fills the screen
|
||||
time; adding a hold would overshoot the measured dwells by ~40 %. The missing
|
||||
hold is only a defect *if* 120 is right. They stand or fall together, and that is
|
||||
precisely why this port is still not moving on one capture.
|
||||
|
||||
## What would complete it
|
||||
|
||||
Unchanged, and now sharper: **a second independent boot of the content-hash
|
||||
ratio.** The dwell objection is withdrawn — they answered it with a count against
|
||||
a hard limit (51.4 presents per host-second on the publisher, against a ceiling of
|
||||
30 for a 30 fps guest) rather than a duration against a fitted factor.
|
||||
|
||||
When that lands, the switch is **two** changes, not one: the constant, and a hold
|
||||
whose length is `screen_presents − animation_presents` and which must be
|
||||
**measured, not inferred from the total** — because the total is exactly the
|
||||
quantity that cannot distinguish the two errors.
|
||||
|
||||
|
||||
---
|
||||
|
||||
# 🔴 WITHDRAWN: "the port has no hold" and "two errors that cancel"
|
||||
|
||||
Both were mine, both were last iteration's headline, and both are wrong.
|
||||
|
||||
## What I misread
|
||||
|
||||
The Decoder gave a split — *"219 presents on screen, ~128 animating"* — and I
|
||||
read it as a hold **outside** the declared timeline, which the port would then be
|
||||
missing. **It is a split *within* the timeline.** The declared group is ramp +
|
||||
hold + fade, and the hold is the largest part of it:
|
||||
|
||||
```
|
||||
publisher palogo_sqex: 0:a=0 15:a=0 30:a=255 235:a=255 239:232 251:32 255:0
|
||||
ramp 0→30 = 30 units
|
||||
HOLD 30→235 = 205 units ← 80.4 % of the screen
|
||||
fade 235→255 = 20 units
|
||||
```
|
||||
|
||||
## The port plays it. Measured, not read
|
||||
|
||||
Frozen samples across the publisher splash, logo region:
|
||||
|
||||
| t | units | region mean |
|
||||
|---|---|---|
|
||||
| 0.25 s | 15 | 0.390957 |
|
||||
| 1.00 s | 60 | **0.405488** |
|
||||
| 2.00 s | 120 | **0.405488** |
|
||||
| 3.00 s | 180 | **0.405488** |
|
||||
| 3.80 s | 228 | **0.405488** |
|
||||
| 4.20 s | 252 | 0.038142 |
|
||||
|
||||
**Identical to six decimals across 168 units.** The port holds, for 80 % of the
|
||||
screen, exactly as declared.
|
||||
|
||||
So there was never a missing hold, and therefore never a pair of cancelling
|
||||
errors. **`authored/timing.json`'s "the pacing was right all along" was right all
|
||||
along**, and my paragraph casting it as a possible coincidence is withdrawn there
|
||||
too.
|
||||
|
||||
⚠️ The failure is worth naming because it is not the usual one: I did not
|
||||
mis-measure anything. **I took a two-part split from someone else's instrument and
|
||||
assumed the boundary was where my own model put it.** Presents are not units, and
|
||||
"animating vs holding" in presents does not decompose the same way as "ramp vs
|
||||
hold" in declared units.
|
||||
|
||||
# ✅ And the port's own data is an independent leg for the time-based clock
|
||||
|
||||
The Decoder's mechanism: `units/present` halved when the present rate doubled
|
||||
while `units/second` did not move, so the UI clock advances by elapsed **time**,
|
||||
not by frame count — and *"2 units per frame"* was a property of a 27 fps capture
|
||||
rather than of the game.
|
||||
|
||||
**The frame-rate work of two iterations ago tests exactly that, and I did not
|
||||
notice at the time.** The same splash, measured across a 4× change in the port's
|
||||
own rendering rate:
|
||||
|
||||
| | frame rate | dwell | implied units/s |
|
||||
|---|---|---|---|
|
||||
| llvmpipe | 17.3 fps | 4.28 s | 59.6 |
|
||||
| llvmpipe | 19.6 fps | 4.26 s | 59.9 |
|
||||
| llvmpipe | 25.0 fps | 4.27 s | 59.7 |
|
||||
| **GPU** | **69.4 fps** | **4.26 s** | **59.9** |
|
||||
|
||||
**Frame rate varies 4.0×; the dwell varies by 0.5 %.** That is the signature of a
|
||||
time-based clock, and it puts the rate at 59.6–59.9 every time.
|
||||
|
||||
🔴 **This is a weaker leg than it looks and I am labelling it rather than
|
||||
counting it.** It shows *the port's* clock is time-based — which it is by
|
||||
construction, `time_units += delta * units_per_second` — so it cannot be evidence
|
||||
about the game's. What it does show is that the **dwell figures I supplied are
|
||||
frame-rate-independent measurements**, not artefacts of whatever rate a run
|
||||
happened to hit. That is the property their argument needs of them, and it is now
|
||||
established from this side rather than assumed.
|
||||
|
||||
# Where finding 3 stands
|
||||
|
||||
**Open, with no surviving named cause.** Units-per-second is eliminated in favour
|
||||
of the value the port already ships; every other candidate died earlier. The
|
||||
clock origin remains untouched, and every quantity in the resolved account is a
|
||||
ratio or a count, so a common offset survives all of it.
|
||||
|
||||
|
||||
---
|
||||
|
||||
# ✅ Settled: the game is frame-based, the port is time-based, and that is correct
|
||||
|
||||
`--framerate_limit=30` — the run this page asked for — refuted the time-based
|
||||
reading on every discriminating row, **against its author's own expectation**:
|
||||
|
||||
| | predicted if time-based | **measured at 30 fps** |
|
||||
|---|---|---|
|
||||
| modal alpha step | 34 | **17** (unchanged) |
|
||||
| units/second | 60 | **30.2** (halved) |
|
||||
| publisher dwell | 4.25 s | **8.450 s** (doubled) |
|
||||
|
||||
Both controls passed *first*: the limiter demonstrably took effect (28.4
|
||||
presents/host-s against 51–55, interval mass moving to two vblanks, 422 of 468),
|
||||
and all 8 splash quad rects were identical, so nothing but the frame rate
|
||||
differed. **`255 × 1 / 15 = 17`** at 28.4, 51.4 and 54.8 presents/s alike.
|
||||
|
||||
## What that changes for the port: nothing — but for a reason worth writing down
|
||||
|
||||
The game advances **1 unit per presented frame**. This port advances
|
||||
`time_units += delta * units_per_second`. **They are different mechanisms that
|
||||
agree at exactly one frame rate: 60 Hz** — which is the only rate the console
|
||||
ever asked the game to be right at.
|
||||
|
||||
🔴 **Do not make the port frame-based to match the game.** A time-based port
|
||||
reproduces a 60 Hz console on hardware that is not 60 Hz; a frame-based one would
|
||||
drift on every machine that is not — and this port has measured *itself* between
|
||||
**9.7 and 69.4 fps** depending on the renderer. Matching the game's mechanism
|
||||
would import a fragility the game never had to survive, because the game only
|
||||
ever ran on one box.
|
||||
|
||||
## 🔴 But it sharpens what `60` is claiming, and makes it falsifiable
|
||||
|
||||
If units/second **is** the present rate, then `keyframe_units_per_second = 60` is
|
||||
no longer "the unit is 1/60 s". It is:
|
||||
|
||||
> **the game presented these screens at 60 Hz on the console.**
|
||||
|
||||
That is a harder claim and a checkable one. **It is also supported for the first
|
||||
time:** Canary unlimited presents at 51–55 Hz and the splash dwell is
|
||||
4.30 / 4.60 / 4.37 s over three cold boots. A natively 30 Hz game would present
|
||||
at ~30 in Canary too — the `--framerate_limit` run proves it, since forcing 30
|
||||
made that same splash take 8.45 s. **It does not take 8.45 s unforced.**
|
||||
|
||||
⚠️ Still `authored`, not promoted to `measured`: this is inference over three
|
||||
measurements rather than a measurement of units per second. It becomes `measured`
|
||||
when someone reads the console's present rate for these screens directly.
|
||||
|
||||
## And it closes the constant as a cause of finding 3 — in the direction that matters
|
||||
|
||||
| console rate | units/s | plate `t=236` |
|
||||
|---|---|---|
|
||||
| 30 Hz | 30 | **7.87 s** |
|
||||
| **60 Hz (shipping)** | **60** | **3.93 s** |
|
||||
|
||||
Under the frame-based model the only alternative is 30 Hz, and it puts the plate
|
||||
**later**, not earlier. **There is no console present rate that makes the plate
|
||||
arrive sooner than this port already shows it.** The human reported it arriving
|
||||
late; no value of this constant can produce that.
|
||||
|
||||
## The method note, and it is theirs
|
||||
|
||||
> *Four of my positions on this number were inference over a measured quantity;
|
||||
> this one changed an input and watched what moved.*
|
||||
|
||||
The opportunistic comparison — two captures that happened to differ — pointed
|
||||
**exactly the wrong way**, because nothing controlled what else differed between
|
||||
them. One designed capture settled it against its author's expectation. That is
|
||||
the difference between an observation and an experiment, and it cost this pair
|
||||
five positions in a day to relearn.

# `verify-screen` DIFFERS on six more screens — it is ADDITIVE, and the port is ahead of the reference
|
||||
|
||||
**Status:** ✅ **RESOLVED.** The reference gained an additive path
|
||||
(`formats-pin-2026-09-01b`) and the divergence this page is about collapses **6×**.
|
||||
Everything below stands; the last section is the measurement that closes it. Port `HEAD` `da7864e` + this
|
||||
commit; HANDOFF at `9ca1eb5`.
|
||||
|
||||
> 🔴 **This page said, in its first version, that the cause was a blend-SPACE
|
||||
> divergence — one renderer linearising and the other not. That was wrong, and
|
||||
> the way it was wrong is the useful part.** Both renderers demonstrably blend in
|
||||
> the encoded space. The transfer curve I built to support it averaged Godot's
|
||||
> value per *reference value* bucket, which collapsed a **bimodal** population —
|
||||
> a large majority differing by ≤1 level and a minority differing by 40+ — into a
|
||||
> smooth-looking curve that resembled gamma and was an artefact of the binning.
|
||||
> A mean over a mixed population is not a transfer function.
|
||||
|
||||
## The measurement that settles it
|
||||
|
||||
53 % of pixels agree to within **1 level** and 69 % to within 3. The rest are not
|
||||
spread over a curve; they are **concentrated in the middle of the frame**:
|
||||
|
||||
```
|
||||
|delta| 0 : 134 969 (cum 14.6 %) > 3 : 282 166 px = 30.6 %
|
||||
|delta| 1 : 355 261 (cum 53.2 %) bbox: the whole frame, but
|
||||
|delta| 2 : 103 348 (cum 64.4 %) occupancy is ~zero in columns
|
||||
|delta| 3 : 45 856 (cum 69.4 %) 0,1,6,7 of 8 and heavy in 2..5
|
||||
|delta| 40+: 16 844 (cum 100 %)
|
||||
```
|
||||
|
||||
The ≤1 tier is integer truncation against float rounding — the reference computes
|
||||
`(sc*sa + dc*(255-sa)) / 255` in `u32` and truncates; Godot rounds. The 30.6 %
|
||||
is something else, and it is in the columns where the menu's content sits.
|
||||
|
||||
## What it is
|
||||
|
||||
**The port draws some elements ADDITIVE. The reference has no additive path at
|
||||
all.**
|
||||
|
||||
`crates/sylpheed-formats/src/ui_layout.rs` has exactly two blend sites, lines
|
||||
1072 and 1174, and both are alpha-over:
|
||||
|
||||
```rust
|
||||
canvas[di + k] = ((sc * sa + dc * (255 - sa)) / 255) as u8;
|
||||
```
|
||||
|
||||
and line 1169 carries the reason — an *"ADDITIVE selector and REFUTED — it moved
|
||||
every metric against the …"*. The reference tried additive, refuted it against
|
||||
its own composite metrics, and does not do it.
|
||||
|
||||
`authored/rendering.json` gives the port an additive set per screen, and its
|
||||
`why` records that this is **transcribed, not authored**: the port proposed
|
||||
additive from a two-background composite solve, kept it a proposal because
|
||||
nothing on the disc selects a blend mode, and adopted it only when the Decoder
|
||||
logged **`RB_BLENDCONTROL0` per draw in Canary** and drove the game to both
|
||||
screens.
|
||||
|
||||
So the two renderers disagree **on purpose**: one implements a measurement of the
|
||||
game's blend register, the other implements a refutation made from composite
|
||||
metrics before that measurement existed.
|
||||
|
||||
## The prediction this makes, and it holds
|
||||
|
||||
If the divergence is the additive set, its size should scale with how many
|
||||
elements are in that set. It does:
|
||||
|
||||
| screen | additive elements in `authored/rendering.json` | mean diff |
|
||||
|---|---|---|
|
||||
| `extras` | **9** — `pteff10 pteff20 ptframe3 ptframe4 pteff21 pteff22 pteff23 ptloop01 ptloop02` | **6.7422** |
|
||||
| `main_menu` | **5** — `pteff12 ptframe1 ptframe2 ptloop01 ptloop02` | **3.9363** |
|
||||
| `main_menu_jp` | **0** — not in the map | 0.7885 |
|
||||
| `extras_jp` | **0** — not in the map | 0.6592 |
|
||||
| `title` | **0** — present, deliberately empty | 0.4431 (the known sweep residual) |
|
||||
|
||||
Nine beats five beats zero, in order, with the two zero-rows an order of
|
||||
magnitude below the two non-zero ones. That ordering was not fitted; the additive
|
||||
map was written before this comparison existed.
|
||||
|
||||
## And which side is right: the port, on the evidence there is
|
||||
|
||||
* the additive set is a **measurement off the running game** — the blend control
|
||||
register, per draw — and the reference's alpha-over is a refutation from
|
||||
*renderer metrics*, which the protocol ranks below a capture;
|
||||
* scored against `docs/re/captures/title-builds/live-main-menu.png`, Godot is
|
||||
**RMSE 3151.96** and the reference **3769.61** — the port is 16 % closer.
|
||||
|
||||
⚠️ **That second line is an ordering and nothing more.** `verify-screen` poses
|
||||
`--pose=rest` and its own header is emphatic that such a frame must never be
|
||||
scored against a capture — that mistake produced a published finding once
|
||||
already. Both sides carry the same pose contamination, so *which* is nearer is
|
||||
still meaningful; *how near* is not. Nobody should quote 0.0481 as the port's
|
||||
fidelity.
|
||||
|
||||
## The blend SPACE, separately: both are encoded, and so is the game
|
||||
|
||||
Worth keeping even though it turned out not to be the cause, because it closes
|
||||
`BLOCKED.md` H4 and it was measured rather than recalled.
|
||||
|
||||
**Godot, measured with a control** — a white quad over black at three known
|
||||
modulate alphas, through the port's own texture path
|
||||
(`load_png_from_buffer` → `ImageTexture`), with the port's `[rendering]` settings:
|
||||
|
||||
| declared alpha | encoded-space prediction | linear-then-re-encode prediction | **measured** |
|
||||
|---|---|---|---|
|
||||
| 64 | 64 | 138 | **64** |
|
||||
| 128 | 128 | 188 | **128** |
|
||||
| 192 | 192 | 225 | **192** |
|
||||
|
||||
Pre-registered before running; exact on all three, with the alternative excluded
|
||||
by 33–74 levels.
|
||||
|
||||
**The reference:** integer arithmetic straight on 8-bit values, no linearisation
|
||||
anywhere in the file.
|
||||
|
||||
**The game:** the Decoder's `blend-space-rt-format.txt` — `RB_COLOR_INFO`
|
||||
`color_format` is `k_8_8_8_8` on 2402/2402 splash draws and 33779/33791 of the
|
||||
boot-to-title capture, `k_8_8_8_8_GAMMA` appears **zero** times, and
|
||||
`color_exp_bias` is 0 throughout. `k_8_8_8_8_GAMMA` is the only format around
|
||||
which Canary applies a gamma↔linear conversion.
|
||||
|
||||
**All three agree. Blend space is not a difference between anybody here**, and
|
||||
the port needs no change for it.
|
||||
|
||||
## The other four rows — localised, and two hypotheses died getting there
|
||||
|
||||
`check-all` still fails on these four, and the allowance was not widened to
|
||||
cover them. What follows is where they are, not yet why.
|
||||
|
||||
### 🔴 Hypothesis 1, refuted: a blend-space divergence
|
||||
|
||||
Covered above. Killed by a control on my own renderer.
|
||||
|
||||
### 🔴 Hypothesis 2, refuted: the port renders `rotation_deg` and the reference does not
|
||||
|
||||
This one looked strong. `ui_layout.rs:86` says so in its own words —
|
||||
*"`rotation_deg` is decoded but NOT rendered"* — and the port does render it. A
|
||||
census over all sixteen exported screens gave:
|
||||
|
||||
> **Every screen with a non-zero rotation at rest DIFFERS, and every screen with
|
||||
> none agrees** — 6 of 6 either way, including both legacy rows.
|
||||
|
||||
**It is still wrong.** Widening the rule to *any* rotating element — a non-zero
|
||||
rest rotation **or** a two-keyframe 360° spinner at any depth — breaks it:
|
||||
`build_00` and `build_01` carry two spinners each and **agree** with the
|
||||
reference. Asked directly, the port's own draw log says it draws both spinners
|
||||
on those screens. So rotation is present, rendered, and produces no difference.
|
||||
|
||||
A rule that holds on 14 of 16 and fails on the two cases nobody had looked at is
|
||||
the shape of a rule fitted to the rows it was built from. Recorded because the
|
||||
next person will find the `ui_layout.rs:86` comment and reach for it too.
|
||||
|
||||
### ✅ What is actually established: `build_12` and `build_15` are ONE element
|
||||
|
||||
All **951** differing pixels lie inside `pgloading_loop5`
|
||||
(`pgloading_ring.png`, 333×276 at `[1,444]`), and the diff's own bounding box —
|
||||
`x 69..301, y 478..710` — sits entirely within it. No other element's rectangle
|
||||
contains a differing pixel that this one does not.
|
||||
|
||||
And that closes the `build_00` / `build_01` question without any rule about
|
||||
rotation: the port's draw log shows those two screens draw **7** elements and
|
||||
`build_12` draws **10**. `pgloading_loop5` is one of the three extra. The
|
||||
loading screens that agree are the ones that never draw the element the
|
||||
disagreement is in.
|
||||
|
||||
Why the two renderers disagree *on that element* is not settled. It is small —
|
||||
max 17, mean 0.0368 — and the element is unusual: its top-level keyframes hold
|
||||
`a=0x7f` for eight units around `rest.t = 24`, while its **leaf** record
|
||||
expands `pgloading_ring` from `scale 0` to `1000` over t=30…130. The port's
|
||||
`draw_leaf_for` lists only `ptloop01` and `ptloop02`, so the port draws the
|
||||
element and not that leaf. Whether the reference does the same is the open half.
|
||||
|
||||
### 🟡 `main_menu_jp` and `extras_jp` — consistent with the sweep leaves, not established
|
||||
|
||||
Both carry `ptloop01/pteff03` (rot 30, at x=1521) and `ptloop02/pteff03a`
|
||||
(rot −45, at x=−839) — the **same sweep leaves** whose phase residual is the
|
||||
already-named reason for `title`. Their means sit with `title`'s and nowhere
|
||||
near their own EN twins':
|
||||
|
||||
| | mean |
|
||||
|---|---|
|
||||
| `title` (sweep residual, named since P1) | 0.4431 |
|
||||
| `extras_jp` | 0.6592 |
|
||||
| `main_menu_jp` | 0.7885 |
|
||||
| `main_menu` (5 additive) | 3.9363 |
|
||||
| `extras` (9 additive) | 6.7422 |
|
||||
|
||||
That is consistent with the JP rows being the sweep residual alone, with no
|
||||
additive contribution — which is what the port's own map implies, since it lists
|
||||
no additive set for them. **Consistent with, not established:** nobody has
|
||||
isolated the sweep leaves on those two screens.
|
||||
|
||||
## ✅ H6 update — the asymmetry has a better answer than a measurement
|
||||
|
||||
The Decoder's reply: the blend is a **decoded disc field**, `T8aD +0x04` bit
|
||||
`0x02` (set ⇒ additive, clear ⇒ premultiplied alpha-over), with a disc-wide check
|
||||
and a surviving out-of-sample prediction. So the port can *derive* the blend per
|
||||
element on every screen instead of transcribing a table, and the JP question
|
||||
answers itself statically — no boot needed.
|
||||
|
||||
**Blocked on one thing:** `sylpheed-formats` does not expose `+0x04`.
|
||||
`ui_layout::Element` surfaces `kind` (`+40`), `parent` (`+32`), pivot, keyframes
|
||||
and `focus_link`, and nothing at `+0x04`; and `crates/sylpheed-export` consumes
|
||||
formats by git **tag**, not by workspace path. Asked as `BLOCKED.md` H6.
|
||||
|
||||
🔴 **And a negative worth having, because it is the obvious thing to try:
|
||||
`kind_raw` in this export is NOT that field.** Its bit `0x2` against the additive
|
||||
map over four screens is **anti-correlated** — 0 of 14 mapped elements have it
|
||||
set, and 9 unmapped ones do (`0x3002` on every button, `0x0` on every element the
|
||||
map lists). Anyone reaching for `kind_raw & 2` will get the additive set exactly
|
||||
inverted.
|
||||
|
||||
## 🔴 The asymmetry, until that lands
|
||||
|
||||
`main_menu_jp` contains **exactly the elements** `main_menu` marks additive —
|
||||
`ptloop01 ptloop02 ptframe1 ptframe2 pteff10 pteff12` — and `extras_jp` contains
|
||||
all nine of `extras`'. The port draws them **alpha-over** on the JP screens and
|
||||
**additive** on the EN ones, purely because `authored/rendering.json` is keyed by
|
||||
screen name and the Decoder's `RB_BLENDCONTROL0` log was taken on the EN screens.
|
||||
|
||||
**The port is therefore asserting, by omission, that the JP build blends the same
|
||||
elements differently — and that is the less likely of the two possibilities.**
|
||||
Extending the map would extrapolate a measurement onto a build nobody drove to,
|
||||
which is not the port's to do; leaving it silent asserts the surprising thing by
|
||||
default. So it is made explicit in `authored/rendering.json` and asked in
|
||||
`BLOCKED.md`, and the map is **not** extended.
|
||||
|
||||
⚠️ It does not affect the deliverable: MISSION §7 puts localisation beyond
|
||||
English out of scope, and the JP screens are not in the boot path.
|
||||
|
||||
## Why `check-all` stays red
|
||||
|
||||
Four rows are **not** explained by the additive set:
|
||||
|
||||
| screen | mean | over3 | note |
|
||||
|---|---|---|---|
|
||||
| `main_menu_jp` | 0.7885 | 3 248 | not in the additive map, yet differs |
|
||||
| `extras_jp` | 0.6592 | 3 163 | same |
|
||||
| `build_12` | 0.0368 | 462 | tiny, and localised — diff bbox `464x266+60+454` |
|
||||
| `build_15` | 0.0368 | 462 | identical figures to `build_12` |
|
||||
|
||||
`build_12` and `build_15` producing byte-identical statistics suggests one shared
|
||||
element rather than two coincidences. None of the four is diagnosed and none is
|
||||
excused.
|
||||
|
||||
## What changed in `check-all`
|
||||
|
||||
The allowance is now **derived** rather than listed: a screen may differ if it
|
||||
has a non-empty additive set in `authored/rendering.json`, plus the two named
|
||||
legacy rows. That is strictly stronger than the hard-coded list — a screen that
|
||||
differs *without* additive elements now fails, which a literal list could not
|
||||
express, and the allowance cannot go stale against the map it is computed from.
|
||||
|
||||
## What this does not claim
|
||||
|
||||
* That the reference is wrong to have refuted additive from its own metrics. It
|
||||
is superseded by a capture, which is a different thing.
|
||||
* That the port's additive set is complete. It covers three screens; nobody has
|
||||
logged the register on the rest.
|
||||
* Anything about the four undiagnosed rows.

# 🔴 Re-validated on the GPU, and my prediction failed: these numbers are rasteriser-specific
|
||||
|
||||
The human activated a hardware GPU on 2026-09-01. **Every number on this page
|
||||
above was measured under `llvmpipe`**, so they needed re-deriving before anyone
|
||||
builds on them.
|
||||
|
||||
## Pre-registered (R2)
|
||||
|
||||
> Both renderers blend in encoded 8-bit space, so if the port's drawing is
|
||||
> rasteriser-independent the diffs should be **identical, or within 1 level**.
|
||||
> Anything materially different means a published conclusion here was
|
||||
> GPU-specific.
|
||||
|
||||
## It failed
|
||||
|
||||
| screen | llvmpipe mean | **GPU mean** | change | max (llvmpipe → GPU) |
|
||||
|---|---|---|---|---|
|
||||
| `title` | 0.4431 | **0.5936** | **+34 %** | 41 → 41 |
|
||||
| `main_menu` | 3.9363 | **4.1449** | +5.3 % | 97 → 97 |
|
||||
| `extras` | 6.7422 | **6.9757** | +3.5 % | 113 → 113 |
|
||||
| `title_jp` | 2.7715 | **2.9448** | +6.3 % | 233 → 233 |
|
||||
| `main_menu_jp` | 0.7885 | **1.0157** | **+29 %** | 26 → 27 |
|
||||
| `extras_jp` | 0.6592 | **0.8906** | **+35 %** | 26 → 26 |
|
||||
| `build_12` / `build_15` | 0.0368 | **0.0454** | +23 % | 17 → 17 |
|
||||
|
||||
**Every mean rose, by 3–35 %.** So the diffs are *not* rasteriser-independent
|
||||
and the prediction was wrong.
|
||||
|
||||
## What survives, and what does not
|
||||
|
||||
🔴 **The maxima are unchanged** — 41, 97, 113, 233, 17 identical, and 26 → 27 on
|
||||
one row. The large differences are exactly where they were.
|
||||
|
||||
That is the shape of a **rounding population growing, not content moving**:
|
||||
llvmpipe and the NVIDIA rasteriser round the last bit of a blend differently, so
|
||||
the ≤1-level tier grows while the elements that genuinely differ do not move at
|
||||
all. Consistent with both still blending in encoded space — which the control on
|
||||
this page established for Godot generally, not for one rasteriser.
|
||||
|
||||
**What survives:**
|
||||
|
||||
* the **additive diagnosis**, because it rests on an *ordering*, and the ordering
|
||||
holds on the GPU: `extras` 6.98 > `main_menu` 4.14 > `extras_jp` 0.89 and
|
||||
`main_menu_jp` 1.02 > `title` 0.59 — nine additive elements, then five, then
|
||||
none;
|
||||
* the **`pgloading_loop5` localisation**, which is a bounding box;
|
||||
* the **`build_00`/`build_01` agree** result — still 0 pixels over the bar;
|
||||
* the **derived allowance**: the failing set is the same four rows.
|
||||
|
||||
**What does not, and is now labelled:**
|
||||
|
||||
* the histogram (*53 % within 1 level, 16 844 over 40*) was llvmpipe-specific and
|
||||
the ≤1 tier is larger on the GPU;
|
||||
* every absolute **mean** quoted above this section;
|
||||
* the **RMSE-vs-capture** pair (3151.96 / 3769.61) was llvmpipe. The *ordering*
|
||||
claim — the port is nearer than the reference — has not been re-derived on the
|
||||
GPU and is not claimed here until it is.
|
||||
|
||||
## The rule this earns
|
||||
|
||||
**A renderer comparison carries its rasteriser as a hidden parameter.** Nothing
|
||||
in this corpus recorded which one produced a diff, and for eight months there was
|
||||
only one so it never mattered. Any diff quoted from here on should say what drew
|
||||
it — the same discipline `TEMPORAL-VERIFICATION.md` already demands for capture
|
||||
rate, applied to the thing that rasterises rather than the thing that clocks.
|
||||

||||

# ✅ Closed: the reference can draw additive now, and the divergence collapses 6×
|
||||
|
||||
The Decoder taught `ui_layout::blit` the additive blend at
|
||||
`formats-pin-2026-09-01b`, on the argument this page made — that the comparison
|
||||
was **structurally incapable**, and that the refutation which had kept additive
|
||||
out was `⟨render-vs-capture⟩`, i.e. that renderer disagreeing with itself while
|
||||
it had a stale keyframe association, no leaf geometry and no rotation.
|
||||
|
||||
**Measured without pulling their branch into mine**: a detached worktree at the
|
||||
tag, `sylpheed-cli` built there, and `verify-screen` pointed at it through
|
||||
`SYLPHEED_CLI`. My branch is untouched and the reference on `main` is unchanged.
|
||||
|
||||
## Pre-registered (R2)
|
||||
|
||||
> With the reference finally able to draw additive, the diffs caused by that gap
|
||||
> should collapse. `main_menu`/`extras` and their JP twins should fall sharply
|
||||
> from ~7, and whatever remains is a *different* cause.
|
||||
|
||||
| screen | alpha-over reference | **additive reference** | factor |
|
||||

| `build_00` / `build_01` | 0.0676, max 60 | **0.0366, max 4** | **DIFFERS → OK** |
|
||||
|
||||
**`build_00` and `build_01` stop differing entirely** — `over3` 3 422 → **0**.
|
||||
|
||||
## And the twins agree to a third of a percent
|
||||
|
||||
| | |
|
||||
|---|---|
|
||||
| `main_menu` 1.2068 vs `main_menu_jp` 1.2111 | **0.36 % apart** |
|
||||
| `extras` 1.0229 vs `extras_jp` 1.0255 | **0.25 % apart** |
|
||||
|
||||
Under the name-keyed map these pairs were 4.1× and 7.8× apart. Nothing was fitted
|
||||
to make that happen — the locale twins converged first when the *port* took the
|
||||
decoded field, and again now that the *reference* draws the same blend.
|
||||
|
||||
## The residual is smaller and its causes are the documented ones
|
||||
|
||||
* `title_jp` 2.82 at max 233 remains the largest, and its named reason —
|
||||
`--pose=rest` sparkle handling — is untouched by any of this.
|
||||
* `title` 0.57 at max 41 is the `ptloop` sweep-phase residual, also untouched.
|
||||
* `main_menu`/`extras` and twins now sit at ~1.0–1.2, max ~28–31. **New, small,
|
||||
and undiagnosed** — additive was the dominant cause and not the only one.
|
||||
* `build_12`/`build_15` do **not** return to their pre-change 0.0368: they land at
|
||||
0.0463 with both renderers drawing `pgloading_loop5` additive. So that element
|
||||
carries a small residual of its own beyond the blend.
|
||||
|
||||
## 🔴 What must happen to `check-all`, and why it has NOT happened yet
|
||||
|
||||
The allowance widened when the reference could not draw additive. **That
|
||||
justification is gone**, so the allowance should be narrowed back and the check
|
||||
should regain its teeth.
|
||||
|
||||
**It is not narrowed in this commit, deliberately.** `check-all` builds the
|
||||
reference from the **workspace** `crates/sylpheed-formats`, and the additive path
|
||||
is at a tag that has not landed on `main`. Tightening now would turn `check-all`
|
||||
red against a reference that still cannot draw additive — a wall of failures
|
||||
meaning one thing, which is the exact defect the display guard was added for.
|
||||
|
||||
**The trigger is mechanical**: when the additive path is on `main`, drop the
|
||||
export-derived clause and leave the two named legacy rows. The set that should
|
||||
then differ is measured above and is `title`, `title_jp`, `main_menu`, `extras`,
|
||||
`main_menu_jp`, `extras_jp`, `build_12`, `build_15` — with `build_00`/`build_01`
|
||||
expected to pass.

## The physical controller: the two buttons Godot does not bind, and the one
|
||||
## input that is not an edge.
|
||||
##
|
||||
## 🔴 BOTH DEFECTS WERE REPORTED BY A HUMAN PLAYING THE PORT (2026-09-01), and
|
||||
## neither could have been caught by the `--script` harness, because that harness
|
||||
## sends `InputEventAction` — which bypasses the input map and is not an analog
|
||||
## axis. The unattended P5 walk passed on every iteration while Ⓐ did nothing at
|
||||
## all on a real pad. **A synthetic-input test asserts the code after the input
|
||||
## map, never the input map itself.**
|
||||
##
|
||||
## ## 1. Godot 4.7.2 binds no joypad button to `ui_accept` or `ui_cancel`
|
||||
##
|
||||
## Measured on this exact build rather than remembered, because the answer has
|
||||
## changed between Godot versions and the remembered one was wrong:
|
||||
##
|
||||
## ```
|
||||
## ui_accept key:Enter, key:Kp Enter, key:Space <- no joypad at all
|
||||
## ui_cancel key:Escape <- no joypad at all
|
||||
## ui_up key:Up, JOYBTN:11, JOYAXIS:1- <- d-pad AND left stick
|
||||
## ui_down key:Down, JOYBTN:12, JOYAXIS:1+
|
||||
## ui_left key:Left, JOYBTN:13, JOYAXIS:0-
|
||||
## ui_right key:Right, JOYBTN:14, JOYAXIS:0+
|
||||
## ```
|
||||
##
|
||||
## That asymmetry is the whole bug report: navigation worked on the pad and Ⓐ/Ⓑ
|
||||
## did nothing, which reads like a broken controller and is a complete input map
|
||||
## for four actions out of six.
|
||||
##
|
||||
## The events are **added to** the built-in actions, never redefined. Declaring
|
||||
## `ui_accept` in `project.godot` replaces the built-in wholesale, so the
|
||||
## keyboard bindings would have to be restated there and would silently rot the
|
||||
## next time Godot changes them.
|
||||
##
|
||||
## ## 2. A stick is not a button
|
||||
##
|
||||
## `ui_up`/`ui_down` are bound to **axis 1**, so the left stick navigates — which
|
||||
## is correct, the real game accepts it too. But an axis emits a fresh
|
||||
## `InputEventJoypadMotion` every time the value *changes*, and a real stick held
|
||||
## at deflection jitters continuously. Every one of those events reports the
|
||||
## action as pressed, so a held stick was one cursor step per jitter: the human's
|
||||
## words were "moves the cursor too fast", and on a five-item menu it crosses
|
||||
## faster than the eye follows.
|
||||
##
|
||||
## So the stick is **latched**: it fires once when it leaves the neutral zone and
|
||||
## not again until it comes back. That makes it behave exactly like the d-pad,
|
||||
## which needs no latch because a button already is an edge.
|
||||
##
|
||||
## ⚠️ ~~AUTHORED, NOT MEASURED — and deliberately the conservative half.~~
|
||||
## 🔴 **THE GAME DOES REPEAT, and this paragraph predicted its own refutation.**
|
||||
## It said: *"If the game does repeat, this is a difference a human will notice
|
||||
## as 'I have to flick it again'."* On 2026-09-02 a human who has played both
|
||||
## reported exactly that — *"holding only moves one item. In game it actually
|
||||
## continues to move when holding up/down, just at a medium pace"*.
|
||||
##
|
||||
## So one-step-per-deflection is no longer the conservative reading; it is a
|
||||
## known defect. The mechanism is implemented below and the **rate is not
|
||||
## shipped** — see `REPEAT_DELAY` for why an approximate one is worse than none.
|
||||
|
||||
## ✅ DECODED 2026-09-01, and it replaces an authored value.
|
||||
##
|
||||
## This was **0.5**, chosen as a *floor* rather than as a value: Godot's action
|
||||
## deadzone for the `ui_*` actions is 0.50, so the latch must not arm below it —
|
||||
## the action itself would not read as pressed and the step would be swallowed
|
||||
## anyway, leaving the latch armed against a press that never happened. That
|
||||
## reasoning still holds and 0.61 is comfortably above the floor.
|
||||
##
|
||||
## The game's own threshold is now measured: it **digitises the left stick to
|
||||
## four direction bits at 61 % deflection**, so it never sees a velocity at all
|
||||
## (`docs/re/input-button-numbering-is-remapped.md` and the corrected
|
||||
## `input-pad-read-path.md`). Between 0.50 and 0.61 Godot reports `ui_down`
|
||||
## pressed and the real game reports nothing; at 0.5 this port stepped there.
|
||||
##
|
||||
## 📌 The mechanism also corroborates the human's fix rather than merely
|
||||
## agreeing with it: a control that digitises to bits cannot express a rate, so
|
||||
## "one step per deflection" is what the hardware layer *can* produce, not a
|
||||
## conservative guess that happened to look right.
|
||||
##
|
||||
## ⚠️ **The 0.11 gap to `RELEASE` stays AUTHORED.** Nothing measured says the
|
||||
## game has hysteresis at all, let alone how wide. Only the arm threshold moved.
|
||||
##
|
||||
## 🔴 **This changes how the stick feels and a human chose the old number.**
|
||||
## Asserted at the device level below and in `tools/port/verify-input`, but a
|
||||
## feel-test is the real check: revert this one constant to 0.5 if 0.61 reads as
|
||||
## a stick that needs pushing too far.
|
||||
const ENTER := 0.61
|
||||
|
||||
## Release lower than it arms. Without the gap a stick resting near 0.5 chatters
|
||||
## across the boundary and re-arms on noise, which is the original bug wearing a
|
||||
## smaller number.
|
||||
const RELEASE := 0.4
|
||||
|
||||
## ## 3. A held direction repeats — MECHANISM PRESENT, RATE NOT SHIPPED
|
||||
##
|
||||
## A human who has played both reported it on 2026-09-02: *"holding only moves
|
||||
## one item. In game it actually continues to move when holding up/down, just at
|
||||
## a medium pace"*, and separately *"Confirmed D-Pad does repeat when holding
|
||||
## too."* So the FACT covers both input devices, which is why `held_direction()`
|
||||
## polls the pad and the keyboard and not just the stick.
|
||||
##
|
||||
## 🔴 **THE RATE IS DELIBERATELY UNSET, AND THE REPEAT DOES NOT RUN UNTIL IT IS
|
||||
## MEASURED.** The instruction is explicit: *"Take the RATE from the Decoder — do
|
||||
## NOT ship a placeholder interval. An invented rate here is indistinguishable
|
||||
## from a measured one later, and this is the exact field where that already cost
|
||||
## us."*
|
||||
##
|
||||
## An earlier draft of this file had 0.40 / 0.20 with a paragraph explaining that
|
||||
## they were authored. **That is precisely the failure mode named above** — the
|
||||
## explanation would have been merged, the numbers would have felt roughly right,
|
||||
## and nothing afterwards could distinguish them from a measurement. They are
|
||||
## removed rather than commented out.
|
||||
##
|
||||
## 📌 **A constant interval is the right SHAPE, and that part IS measured.** The
|
||||
## game digitises the left stick to four direction bits at 61 % deflection
|
||||
## (`ENTER` above), so it cannot see deflection magnitude at all — a repeat it
|
||||
## drives cannot be faster-the-harder-you-push. That excludes the one competing
|
||||
## model, so only the two constants are open, and one measurement closes both.
|
||||
##
|
||||
## ⚠️ **TO ADOPT, TWO THINGS CHANGE, NOT ONE.** Set both constants to the
|
||||
## measured seconds — and update `tools/port/verify-input`, whose row *"a held
|
||||
## stick is ONE step, not six"* currently asserts **the absence of this
|
||||
## feature**. It passes today because the repeat is inert; the moment a rate is
|
||||
## adopted a held stick SHOULD produce further steps, and that green row would
|
||||
## go red for the right reason and be read as a regression.
|
||||
##
|
||||
## 📌 That row is not wrong. A check written against today's behaviour becomes an
|
||||
## assertion that the behaviour never changes, and this one has the additional
|
||||
## trap of looking like a bug-fix regression test — it was written for the
|
||||
## jitter defect, and the repeat is not that defect returning.

## 🔴 WHY THE DRAWING GOES THROUGH `RenderingServer` AND NOT `draw_texture_rect`.
|
||||
##
|
||||
## Godot sets the blend mode on a CANVAS ITEM, not on a draw call, so an additive
|
||||
## element cannot simply be drawn differently inside one `_draw()`. The measured
|
||||
## fact is per element (`authored/rendering.json` `additive_elements`), so the
|
||||
## screen is split into RUNS of consecutive paint-order entries sharing a blend
|
||||
## mode and each run gets its own canvas item, ordered by `canvas_item_set_draw_index`.
|
||||
##
|
||||
## ⚠️ The obvious implementation -- child `Node2D`s with a `CanvasItemMaterial`
|
||||
## each -- LOSES A FRAME. `boot.gd` calls `view.queue_redraw()` from nine places
|
||||
## and none of them reaches a child node, so the bands would paint the previous
|
||||
## pose. A capture taken with `--script=wait` would have shown that as a plausible
|
||||
## wrong answer rather than as an error. These items are filled synchronously
|
||||
## inside `_draw()` instead, so there is no second node to keep in step.
|
||||
## 🔴 CANVAS ITEMS MADE THROUGH `RenderingServer` ARE NOT OWNED BY THE NODE, and
|
||||
## the first version of this file did not free them: Godot printed
|
||||
## `5 RIDs of type "CanvasItem" were leaked` on every exit -- exactly the number of
|
||||
## paint-order runs on the main menu. A node-owned child would have been collected
|
||||
## for me; the reason for using the server directly is in `_band`, and this is its
|
||||
## price. `_exit_tree` rather than `NOTIFICATION_PREDELETE` because the items are

"""What does each `kind` label in `authored/` actually REST on?
|
||||
|
||||
Every authored entry carries a `kind` -- `measured`, `authored`, `name match,
|
||||
not measured` -- and a `why`. The label is the load-bearing part: `measured`
|
||||
means the port is repeating something observed off the running game, and a
|
||||
reader downstream will treat it as fact.
|
||||
|
||||
Nothing has ever checked them. That is the point: **a discipline that has never
|
||||
visibly failed is the one nothing directs attention at.** The Decoder reached
|
||||
this from the input side -- Ⓐ and Ⓑ were delivery-confirmed because they had
|
||||
once broken, so the d-pad never was -- and on the same day a `measured` label of
|
||||
mine turned out to rest on a single entry that may have been measuring history.
|
||||
|
||||
So this checks what is checkable about a label, and is explicit that the rest is
|
||||
not:
|
||||
|
||||
citations resolvable references in the `why` -- a `docs/` path that exists on
|
||||
some ref, a commit sha that resolves, a capture filename
|
||||
BARE a label whose `why` cites nothing a reader could go and open
|
||||
DANGLING a citation that does not resolve anywhere in the repository
|
||||
|
||||
🔴 What it CANNOT do is read the cited page and confirm it says what the `why`
|
||||
claims. A label with three resolvable citations can still be wrong. This narrows

||||
"which labels rest on nothing" from unknown to a list; it does not audit meaning.

"""Date every open row in BLOCKED.md from history, instead of guessing.
|
||||
|
||||
`BLOCKED.md` is required to record the HANDOFF commit each row derives from, and
|
||||
none of the rows in the two open tables do. The file itself says why: nobody
|
||||
knows when most of them were written, and inventing a sha would be worse than
|
||||
admitting there is none.
|
||||
|
||||
But git does know. A row's derivation is not a memory, it is the commit that
|
||||
introduced the row -- recoverable with a pickaxe over the file's own history.
|
||||
This prints, per row:
|
||||
|
||||
introduced the oldest commit whose diff added the row's key phrase
|
||||
HANDOFF@ `git log -1 -- docs/port/HANDOFF.md` as of that commit
|
||||
unread commits touching docs/re/ ON ANY REF that are not ancestors of
|
||||
that commit -- decoding the row has never been read against
|
||||
|
||||
`--all`, not my own ancestry, and that distinction is the whole finding. Counted
|
||||
against my checkout every row scores ZERO, which is true and useless: the
|
||||
Decoder's live decoding sits on `origin/auto/no-disc-and-menu-captures`, `main`
|
||||
is a hundred-odd commits behind it, and HANDOFF has not moved in four
|
||||
milestones [refuted] -- 🔴 corrected 2026-09-01: **on `main`**. Flat, that
|
||||
sentence is the claim this port WITHDREW in `BLOCKED.md` on 2026-08-30, where the
|
||||
missing qualifier was recorded as carrying the whole meaning: HANDOFF has moved
|
||||
over a hundred times, just not on the branch this checkout reads. The reasoning
|
||||
below needs the qualifier to work at all -- the sha is constant BECAUSE `main`'s
|
||||
copy is frozen, not because the document is. So a row can be derived from the
|
||||
newest HANDOFF `main` has and still
|
||||
be a day behind the decoding -- and the instruction to record the HANDOFF sha
|
||||
CANNOT DETECT THAT, because the sha it asks for is constant.
|
||||
|
||||
That is the rot mechanism the 2026-08-30 audit found three instances of, and it
|
||||
is not the one the header of BLOCKED.md describes.
|
||||
|
||||
Nothing here is authored. Every field is read out of git, and a row whose key
|
||||
phrase has been rewritten since it was introduced reports `?` rather than a
|
||||
plausible-looking sha.

#
|

# `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

|
||||
# 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

#

# TRIGGER, so this does not rot: when `grep -q additive crates/sylpheed-formats/src/ui_layout.rs`

# 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

# 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

||||
|
||||
* a RELAYED number pointed at the wrong element drifts from the declared one;
|
||||
* a RE-EXPORT that re-times a keyframe moves the declared one underneath an
|
||||
authored value that was correct when written.
|
||||
|
||||
Both look like nothing. Neither is caught by `audit-kinds`, which checks that a
|
||||
`why` cites something, not that the number still agrees with the disc.
|
||||
|
||||
⚠️ NAME THE RECORD, NOT JUST THE ELEMENT. An audit of these values was read by
|
||||
the other agent as covering `ptbtn00f`'s peak alpha, and they reported it
|
||||
undeclared -- because they looked at `ptbtn00.rat`'s LEAF, which declares
|
||||
`ptbtn00.t32` at a flat `0:255`. The pulse is in a DIFFERENT record,
|
||||
`ptbtn00f.rat`, reached through `focus_link`, and it declares
|
||||
`0:0 6:6 29:74 35:80 50:80 58:74 97:6 105:0`. Both records carry a 120-unit
|
||||
loop. Saying "declared" without saying *in which record* cost a round trip, so
|
||||
this prints the record it compared against.
|
||||
|
||||
⚠️ SCOPE, deliberately narrow. Only values with a declared counterpart are
|
||||
checkable here. A measured constant with no disc equivalent -- the leaf rate
|
||||
itself, for instance -- cannot be verified this way and is not pretended to be.

#
|

# WHY THIS EXISTS. A 6-channel capture of the game's own output was analysed at
|
||||
# length -- three controls, a drift test, a written-up negative -- and the file
|
||||
# was corrupt. PulseAudio was remapping between two mismatched channel maps, and
|
||||
# a 6-channel remap SILENTLY DROPS AND DUPLICATES: right duration, right channel
|
||||
# count, plausible per-channel levels, no error anywhere. Two of the six channels
|
||||
# were byte-identical copies of two others and two source channels were simply
|
||||
# gone.
|
||||
#
|
||||
# The Decoder proved it with a control that needs no emulator and no disc: six
|
||||
# channels each carrying a different tone through the same sink and the same
|
||||
# `parec` invocation. Channels came back 400 / 3200 / 200 / 800 / 800 / 200 for
|
||||
# an input of 400 / 800 / 200 / 1600 / 3200 / 6400 -- see
|
||||
# `docs/re/audio-capture-channel-map-trap.md`. Setting the sink's `channel_map`
|
||||
# to the guest's own and passing the same map to `parec` returns all six.
|
||||
#
|
||||
# THE DETECTABLE SIGNATURE IS AN EXACT DUPLICATE PAIR. Two channels of a real
|
||||
# surround mix are never byte-identical over 70 s. Levels are not enough to catch
|
||||
# it -- the corrupt file's per-channel peaks looked entirely reasonable, and it

# BYTE-IDENTICAL output: the original, one with `-t 8` bounding the output, and

# one with explicit `asplit` feeding each `atrim` (the textbook fix for

# multi-use of a single input). So it is not the split, not the output stage,

#
|

# ⚠️ Worse than the hang: it LEAKS. An orphaned ffmpeg from this script's earlier

# `aloop` form was found still running after **9.5 hours**, burning CPU across

# runs nobody was watching. `boot.gd`'s own header already names this failure

|

`port/manifest.json`, `port/screens/title/*.json`. Left behind by the

🔴 WHY. The other agent got a value wrong by resolving a record BY NAME and
|
||||
stopping at the first hit: `ptbtn00` carries two children, and its pulse lives in
|
||||
the second. Their census puts 1467 of 15493 elements -- 9.5%, across 815 builds --
|
||||
behind that second link, and they asked how exposed this exporter is.
|
||||
|
||||
Measured answer at the time of writing: **not at all**. 116 links resolve through
|
||||
an exported `focus` block's `record`, 19 resolve to a top-level element on the
|
||||
same screen, and **0 reach nothing**. But that is a property of today's tree, and this port is
|
||||
adding archives -- `GP_OPTIONS` landed today and `GP_SAVE_LOAD`, `GP_TUTORIAL`
|
||||
and `GP_DIALOG` are each one line away. A link into a record the exporter does not
|
||||
emit would be invisible: the element still draws, it simply loses an animation
|
||||
nobody knows to look for.
|
||||
|
||||
⚠️ `opt_link` is NOT "the focused state of a button", whatever the parser's field
|
||||
name says. On this export it also chains `pgloading_loop1 -> loop3 -> loop4` (three
|
||||
loop animations) and `ptloop01 -> ptloop02` (the two title sweeps), and on
|
||||
`main_menu` it runs sweep -> sweep -> button -> button-variant. It links records;
|
||||
focus is one use of it. This check therefore accepts EITHER resolution and does
|
||||
not care which, because caring would be believing the name.

"""Reconcile the numbers the CONTRACT states against the numbers the PORT ships.
|

|

`docs/port/HANDOFF.md` is the contract, and this port reads it from `main` --
|
||||
where it is frozen at 926 lines while the live document, on the Decoder's branch,
|
||||
is 4 111. Two days of deliveries addressed to the port landed on a page the port
|
||||
does not open. Reading 70 unread sections by hand is how that gets missed again.
|
||||
|
||||
So the values are checked instead of read. Each check names a quantity, pulls it
|

OUT OF THE LIVE HANDOFF TEXT by pattern -- never restating it here, or this file
|
||||
would be a third copy to go stale -- and compares it against the port's own
|

`export/` tree or `authored/` mapping.
|
||||
|
||||
Three outcomes, and the third is the point:
|
||||
|
||||
ok the contract and the port agree
|
||||
MISMATCH they disagree; one of us is wrong and this says which values
|
||||
ANCHOR the pattern no longer matches the contract -- the check has STOPPED
|

CHECKING. Reported as loudly as a mismatch, because a check whose

anchor has drifted passes forever while measuring nothing.

Reads the newest HANDOFF on ANY ref, not the working tree's, and says which.

🔴 WHEN A CHECK GOES `ANCHOR LOST`, ADD A SECOND NARROW ANCHOR -- DO NOT LOOSEN
|

THIS ONE. The temptation is to make the pattern general enough to survive any
|

rewording, and a general matcher fails in a way you have not met yet instead of
|
||||
one you can see. The Decoder reached this the expensive way: a narrow calibrated
|

reader failed, they replaced it wholesale with a whole-frame comparison, and the

swap felt like rigour until a crash dialog overlaid the frame and killed the

🔴 WHY THIS EXISTS. F6 asked "when does the title sweep start?" Both agents spent
|
||||
three exchanges on ALPHA -- a bound, a refutation, a downgrade -- and the answer
|
||||
was sitting in a POSITION series nobody compared to anything.
|
||||
|
||||
Alpha is the weakest observable we have: 8 bits, quantised, and the argument that
|
||||
collapsed did so on a 14-sample tail out of 1754, where a vertex-grouping slip
|
||||
looks exactly like a signal. The sweep's POSITION travels 2 160 px, monotonically,
|
||||
and is immune to every one of those failure modes.
|
||||
|
||||
📌 The generalisation, which is the reusable part: **when something moves, its
|
||||
POSITION carries the clock and its ALPHA carries almost nothing.** A trajectory
|
||||
fit yields the clock ORIGIN and the RATE together, and its residual says whether
|
||||
the model was right at all -- which a value-at-an-instant never does. This is
|
||||
`TEMPORAL-VERIFICATION.md`'s "align by content" made into arithmetic.
|
||||
|
||||
WHAT IT DOES NOT DO. It fits t = t0 + rate * frame, i.e. a constant rate. If the
|
||||
guest's clock stalls or the capture drops frames unevenly, the residual rises and
|
||||
the tool says so rather than absorbing it -- that is the point of reporting RMS
|
||||
rather than just the parameters.

|

# tools/port/verify-capture # every screen with a capture
|

#
|
||||
# THIS IS THE CORRECTNESS CHECK. `verify-screen` is the consistency one, and its
|
||||
# own header has pointed at this file since P1 -- `tools/port/verify-capture` -- while
|
||||
# this file did not exist. The port has had a harness comparing two renderers
|
||||
# that share its assumptions, and none comparing it to the game.
|
||||
#
|
||||
# 🔴 WHAT THE `diff` COLUMN DOES NOT SAY. It counts pixels surviving
|
||||
# `-threshold 25%` -- differing by more than ~64 levels. That is deliberate: it
|
||||
# detects a missing or MISPLACED element, which is a large connected blob. It is
|
||||
# blind to sub-threshold spatial error -- a one-pixel offset, a soft edge in a
|
||||
# slightly wrong place, an antialiasing difference -- because none of that moves
|
||||
# a pixel 64 levels.
|
||||
#
|
||||
# So `main_menu 0.06%` means NO GROSS DISPLACEMENT. It does NOT mean the
|
||||
# geometry is right, and it has already been read that way by another agent:
|
||||
# `docs/re/structures/title-residual-tone-vs-geometry.md` uses this screen as a
|
||||
# tone-only positive control, citing this number as "geometry is essentially
|
||||
# right". Measured 2026-08-31 against that capture: after fitting a per-level LUT
|
||||
# -- the most general tone model there is -- the remaining residual is 6.94 on
|
||||
# edge pixels against 2.20 on flat ones, a 3.2x concentration. A purely tonal
|
||||
# residual leaves a per-level LUT exactly 0.00 (checked, by construction). The
|
||||
# menu carries spatial error this column cannot see.
|
||||
#
|
||||
# ⚠️ That gap is not academic. `docs/re/captures/ORACLE-CAPTURES.md`: two
|
||||
# renderers agreeing proves nothing, and this corpus has been bitten three times
|
||||
# -- the dropped `pteff05` background, the scale-0 rect, and `rest()`. Every one
|
||||
# was invisible to a render-vs-render diff and obvious against a capture.
|
||||
#
|
||||
# WHAT IT CAN CONCLUDE, and what it cannot:
|
||||
#
|
||||
# * ✅ STRUCTURE. Something drawn that should not be, or missing that should be,
|
||||
# shows as a large connected region of difference. That is the failure mode
|
||||
# the three above were, and it is what this tool is for.
|
||||
# * 🔴 NOT a pixel score. The captures are NOT gamma-neutral:
|
||||
# `capture ~= 255*(render/255)^g` with g ~ 1.34-1.49, and that ramp is THE
|
||||
# GAME'S, not the capture path's (`docs/re/structures/ui-render-tone-curve.md`).
|
||||
# So RMSE has a floor and driving it lower is fitting the ramp. This reports
|
||||
# the raw difference AND the gamma-compensated one, and neither is a target.
|
||||
# * ⚠️ A capture is ONE MOMENT. Several screens are still animating -- the
|
||||
# title's two `ptloop` sweeps never stop -- and the focused button in a
|
||||
# capture may not be the one the port focuses. Differences confined to a
|
||||
# button or a moving element are expected; say which before calling anything.
|
||||
#
|
||||
# Geometry needs no correction: the corpus cross-correlated a render against
|
||||
# `live-main-menu.png` over +/-6 px and the best alignment is exactly (0,0) at
|
||||
# 0.9466. The captures are a 1279x675 top-left crop of the 1280x720 guest
|
||||
# surface, so the render is cropped to match and nothing is scaled.

#
|

# t=357.7 is the Decoder's REFINED fit, and the refinement is worth knowing.
|

# Its first value, 355, came from the two per-draw alpha bytes alone and left
|

# an 11.5 px residual that looked like a pivot problem. Solving the same

# instant on the vertex POSITIONS instead gives t=357.88 and 357.58 to
|
||||
# +/-0.12 units, against +/-1.54 and +/-1.89 from the alphas -- alpha moves
|

# only 0.27-0.33 levels per unit, so one byte of quantisation is worth 6-8 px

# of sweep. At 357.7 the centres land within 0.70 px and both alphas inside one

|

# WHY THIS IS A TOOL AND NOT A ONE-OFF. Doing it by hand once already refuted a
|
||||
# 🔴 I had filed myself: `docs/port/BLOCKED.md` said `rest.t` was the wrong settle
|
||||
# landmark AND that "everything the sequencer paces off it is therefore late".
|
||||
# The first half is true; the second was wrong, and I nearly re-paced screens
|
||||
# that already matched the game to 0.05 s.
|
||||
#
|
||||
# ⚠️ A PORT'S TRANSITION INTERVAL IS NOT THE ORACLE'S VISIBLE SPAN. They differ
|
||||
# by the black hold between screens, and confusing the two cost this corpus 0.6 s
|
||||
# once and 0.48 s on the plate delay. So the comparison here is explicit: the
|
||||
# port's interval is checked against the oracle's span PLUS the measured hold.
|
||||
#
|
||||
# 🔴 AND THE VERDICT DOES NOT COME FROM THE FILMSTRIP ANY MORE. It used to
|
||||
# measure ink spans from `--film` frames. The boot's black hold is 0.17-0.23 s
|
||||
# (HANDOFF Q7) -- shorter than the 0.25 s cadence meant to observe it -- so when
|
||||
# the black frame fell between samples two screens merged into one span and this
|
||||
# tool reported `developer logos` as 93 s against an oracle of 3.5 s. Filming at
|
||||
# 0.1 s made it WORSE: 2.5x the screenshots slows the run enough that the capture
|
||||
# catches up in bursts, and the publisher span came back as 7.80 s.
|
||||
#
|
||||
# The sequencer already knows exactly when it changed screens and prints it.
|
||||
# Sampling a picture to rediscover a number the program can state is how this
|
||||
# went wrong. The filmstrip is kept, and marked advisory.
|
||||
#
|
||||
# THE EXPECTED NUMBERS ARE THE ORACLE'S, NOT THE PORT'S: three cold boots from

# nothing. Skipping the intro did nothing; opening a submenu did nothing. The

# unattended P5 walk had passed on every iteration while this was true, and the
|

# reason is exact:
|
||||
#
|
||||
# `--script` sends `InputEventAction`, which BYPASSES the input map.
|
||||
#
|
||||
# So the harness asserted every line of code *after* the input map and nothing
|
||||
# about the map itself -- and the map was missing half the actions. Godot 4.7.2
|
||||
# binds NO joypad button to `ui_accept` or `ui_cancel`, while it binds the d-pad
|
||||
# AND the left stick to `ui_up`/`ui_down`. Four actions worked on the pad, two
|
||||
# did not, which reads as a broken controller.
|
||||
#
|
||||
# The second defect had the same blind spot: `InputEventAction` is not an analog
|
||||
# axis, so the harness could not have seen that a held stick fires once per
|
||||
# jitter. The human's words were "moves the cursor too fast".
|

#
|

# ⚠️ THE GENERAL LESSON, worth more than either fix: **a synthetic-input test

# frozen sweep (`--time=`) proves the renderer CAN draw pose N. It drives the

# nor an implied key -- so without the forced-backdrop pass the first element

# the pass, both screens render at max 214.5 in BOTH renderers (mean 1.949

# reader who hits a blank pair tomorrow needs it.

"""Is the transcode faithful to the source? Decode both, align, subtract.
|
||||
|
||||
`AUDIO-VERIFICATION.md` §1 states this as the question P4 actually raised and
|
||||
gives the method, and nothing implemented it. `verify-video-audio` deliberately
|
||||
does not: it proves Godot emits non-silence and says in as many words that a
|
||||
difference RMS without alignment is meaningless. So the gate has rested on level
|
||||
and non-silence, and the fidelity claim has never been made.
|
||||
|
||||
The doc names three ways the measurement lies, and all three are handled here
|
||||
rather than hoped about:
|
||||
|
||||
ALIGNMENT a one-sample offset makes the difference nearly as loud as the
|
||||
source. Cross-correlated coarse-to-fine BEFORE subtracting, and
|
||||
the search REFUSES when its best lag sits on the boundary --
|
||||
printing the range beside the answer, so an edge reads as an
|
||||
edge.
|
||||
CHANNEL LAYOUT the source is 5.1 and the transcode is stereo. The source is
|
||||
folded with `video.rs`'s own `DOWNMIX_51` -- read out of the
|
||||
manifest's recorded command, not restated here -- so both sides
|
||||
are the same fold.
|
||||
A PARTIAL FILE `ffprobe` once reported 33 s for a 137 s transcode because the
|
||||
encode was still running. Duration and mtime are checked, and a
|
||||
file written in the last 60 s is refused.
|
||||
THE SEEK `-ss` before `-i` returned 4.6 s of AUDIO for a 4.0 s request on
|
||||
this WMA Pro source, so the two windows covered different audio.
|
||||
Not in §1. ⚠️ NARROWED after the Decoder checked it: on this
|
||||
disc the VIDEO container-seek is EXACT -- a frame taken at 20 s
|
||||
via container seek is byte-identical to one from a full decode.
|
||||
So it is a property of the AUDIO STREAM, not of `-ss` placement
|
||||
as such, and a check that only looked at video would clear a
|
||||
path still unsafe for audio.
|
||||
|
||||
🔴 AND IT RUNS ITS OWN KNOWN NEGATIVES. A fidelity check that has only ever
|
||||
returned "faithful" is the unfalsifiable clean run this project keeps finding:
|
||||
`--control` compares the source against itself (must be near-perfect) and against
|
||||
the OTHER movie (must be near 0 dB down).
|
||||
|
||||
⚠️ **REPORT ONLY. THIS DOES NOT YET PRODUCE A VERDICT**, and it is committed in
|
||||
that state deliberately. It has reproduced four distinct ways the measurement
|
||||
lies -- three that §1 names and one it does not -- and each was found by a
|
||||
diagnostic rather than by reasoning. It still reports the difference signal
|
||||
LOUDER than the source, which cannot be true of two aligned signals at equal
|
||||
level, so the remaining fault is on this side of the instrument.
|
||||
|
||||
A tool that says "not faithful" while its own alignment is broken would be worse
|
||||
than no tool: it would put a false defect on the exporter. Committed so the next
|
||||
iteration starts from four known traps instead of from four lines of shell.

-- **1 s of misalignment costs 0.16 dB**, well inside the 1.5 dB pass band --

strong; the honest claim is robustness up to a few seconds.

necessary. `af` applies to the LEFT side only, which is correct for the real

comparison -- a 5.1 source needs folding, an already-stereo transcode does

not. Applying that same asymmetry to source-against-itself compares a folded
