agents: rewrite the briefs for the Gitea workflow

Browse Source 
The two loop files ARE the prompts -- `sylph-port` and `sylph-decoder` read them
off the host at launch -- so the workflow change had to land here or it would
not reach the agents at all.

PROTOCOL.md gains four sections:

  * Work items -- issues, milestones as bundles, the state labels, and that
    `state/blocked` uses DEPENDENCY EDGES, never prose. A prose blocker is what
    let a 1,227-line BLOCKED.md go stale.
  * Messages -- an ask is a `kind/ask` issue, not a SendMessage. With the part
    that matters: 🔴 NOTHING PUSHES. Notifications are polled, at the top of
    every iteration, and therefore an agent must NEVER wait on an ask -- set the
    edge, take the next item. The channel this replaces dropped 21 consecutive
    messages to a stale session id and reported success each time.
  * Pull requests -- one item per branch, `Closes #N`, and you may not merge
    your own. Branch protection enforces it; the rule is written down so the
    agent knows it, not so it depends on the agent.
  * Each iteration, in order -- notifications, sync, one unit, hand over, stop.

Also: evidence a human must look at now attaches to its issue, and a blunt
"never commit game content, under any directory name" with the 545 MB that
prompted it.

The two briefs shrink 697 -> 298 lines. They had accreted five dated focus
blocks between them -- sole-focus orders, F1-F6 queues, one-off "merge this
branch on your first iteration" instructions -- which is a queue, and a queue
belongs in the tracker. What is KEPT is what outlives its bug:

  * ask of any check, what would this still report if the feature were absent?
    Three instruments passed a splash that never animated.
  * the instrument must sit at or above the thing that can break -- the
    InputEventAction / input-map miss.
  * R1, and grep REFUTED.md before proposing.
  * the .pe is primary and the database is somebody's analysis of it.
  * the oracle is the real game in Canary, not any renderer of ours.

⚠️ NOT YET TRUE when this lands: the agents have no Gitea users, no API tokens
and no MCP server, so the issue tooling these briefs assume does not exist yet.
The agents are stopped. Setting that up is the prerequisite for restarting them.

## Work items: Gitea issues
**Changed 2026-09-04. This replaces `BLOCKED.md` and the direct message channel.**
Every unit of work is an **issue** in `fabi/Sylpheed`. Milestones are **bundles**
the human defines; you decompose a bundle into items and the human approves the
shape before you start. Labels carry the state:
```
state/proposed → state/approved → state/in-progress → state/needs-human → closed
↘ state/blocked
```
`state/needs-human` is the state this whole project turns on. An issue in it must
say **what to look at** and **what pass and fail look like**, so a person can
judge it in under a minute without reading anything else.
⚠️ **`state/blocked` uses Gitea's dependency edges, never prose.** *"Blocked on
the Decoder answering X"* is a link that closes itself when X closes. A sentence
is not, which is how a 1,227-line `BLOCKED.md` went stale.
## Messages
Agents talk directly. Traffic is **pointers and priorities**, not content.
Traffic is **pointers and priorities**, not content. An ask to the other agent is
an **issue** labelled `kind/ask`, assigned to them, with a dependency edge from
whatever it blocks — plus an `@mention` so it reaches their notifications.
### How, concretely
### 🔴 Notifications are POLLED. Nothing pushes to you.
This section exists because the first version of this page specified the policy
and forgot the mechanism, and two agents then ran for hours without exchanging a
word — each knowing exactly what a message *may* contain and not that the other
was addressable.
There is no mechanism that interrupts a running session. **Read your
notifications at the top of every iteration** — that is the only way anything
addressed to you arrives.
```
ListAgents # who is reachable
SendMessage(to: "sylpheed-agent", message: "...") # the Decoder
SendMessage(to: "sylpheed-port", message: "...") # the Port
```
Two consequences, and the second matters more:
Both register under those names at startup. **Introduce yourself on your first
iteration** — say which role you are, which branch you are on, and what you are
working toward. Do not wait to have a question.
* your reply latency is one iteration. That is fine and it is designed for.
* **never wait on an ask.** Open it, set your own item `state/blocked` with the
dependency edge, and **take the next item**. An agent blocking on a poll is an
agent doing nothing.

## 🔴🔴 SOLE FOCUS, 2026-09-02: **THE TITLE'S ANIMATION TIMING — F5 and F6, nothing else**
You do **not** build the port. If you find yourself writing GDScript or designing
an export schema, stop and go back to the question you were answering.
**Work only these two.** Not the pipeline, not the audio mix, not the repeat
rate — they stay queued in
[`PLAYTEST-2026-09-02-menus.md`](PLAYTEST-2026-09-02-menus.md).
## 🔴 The working surface changed on 2026-09-04. Read this before anything else.
> *"Let's have the agents focus on this item and only this only."*
**Work is tracked in Gitea issues, not in `BLOCKED.md`. Changes reach `main`
through pull requests.** The rules are in [`PROTOCOL.md`](PROTOCOL.md) — the
*Work items*, *Messages*, *Pull requests* and *Each iteration* sections are all
new. Read them.
**F6 first** — it is the one with a lead. A human reports that the title's
sweeping white glow (**`ptloop01` / `ptloop02`**, the blue PCB-like lines) **only
starts when the plate appears** in the real game, while the port starts it
earlier. `title.json` declares those elements at `t = 0, 70, 100, 238, 250` and
the plate reaches full alpha at **`t = 236`** — with `pteff02` keyed at exactly
236 and `ptlogo_back2eff`/`ptcopyright` at 238. **236–238 is a synchronisation
point in the declared data and a human just reported a behaviour change there.**
⚠️ `238…250` may equally be an **exit ramp** (`ptcopyright` uses that shape and
starts nothing), and the sweep lives in a nested `.rat` leaf with its own
timeline. Establish which of the two the human is watching.
Three things that will bite you if you skim:
**F5 second** — does Ⓐ **snap** the title to finished, or **accelerate** it? The
human says they cannot tell, and is right that they cannot: a three-frame
acceleration and a one-frame cut look identical to an eye. Two routes, and they
should agree: a **per-frame capture** (an acceleration shows intermediate alphas,
a cut shows none) and **the code** (assigning a target time and raising a rate
multiplier are different instructions). Their *"looks more like a snap"* is a
**prior, not a result** — say so if the measurement disagrees.
1. **Nothing pushes to you.** Notifications are polled. Read them at the top of
every iteration or nothing addressed to you ever arrives — including the
Port's asks, which are now `kind/ask` issues assigned to you.
2. **Never wait on an ask you sent.** Set the dependency edge, take the next
question.
3. **You cannot close your own work.** You move an item to `state/needs-human`
with a one-line "look at this, pass looks like X". The human closes it.
### And split it before you start
**Read the new "Work in units a human can check in a minute" section of
[`PROTOCOL.md`](PROTOCOL.md).** The human's diagnosis is that whole missions have
been too big to hold. Break even F6 down, write the question and the
look-at-this-and-you-will-see before working, do one, hand it over, stop.
## ✅ THE LOGO SPLASHES ARE DONE — signed off by the human, 2026-09-02
> *"Looks good! Cannot notice any obvious difference from the actual game.
> Mark logos as done."*
**The sole-focus order is lifted.** The port's defect was `pose_at` assigning the
settle instant rather than clamping to it; your per-frame measurement of the real
game (28 distinct alphas over 28 consecutive presents, modal steps −3 and −14
against predicted −2.87 and −14.13) is what let their fix be checked for *shape*
and not merely for motion. That is the pairing this team is for.
### 🔴 The pipeline work is STILL THE RIGHT WORK — continue it, at normal priority
It was cut short by the sole-focus order, and it remains the thing that decides a
question the port cannot answer about itself: **the port matches its own declared
keyframes; nobody has established that its 60 units/s matches the game.** The
ramp is right in shape and unverified in duration.
So carry on with the end-to-end account, unchanged in substance:
```
disc bytes → RATC/T8aD decode → what the GAME CODE does per frame
→ the draw calls it submits → Canary's own processing
→ the presented frame
```
The three load-bearing questions stand, and the first is now the most valuable:
1. **The per-frame update** — which function advances a UI group's clock, in what
units, and **what it does between keyframes**. The port interpolates
piecewise-linearly across declared segments and your capture agrees; the
remaining gap is the *rate*.
2. **What is submitted per frame** during a screen's build-in, as a series.
3. **What Canary does to it** before a capture records it — present cadence,
resolve, scale, gamma.
### 🔴 Four asks from the 2026-09-02 menu play-test — [`PLAYTEST-2026-09-02-menus.md`](PLAYTEST-2026-09-02-menus.md)
P5's gate is **met** (a human walked the menus). These came out of the same
session, and three of the four are yours. They are ahead of the pipeline work
because the port is blocked on two of them.
1. **F1 — MEASURE THE MENU REPEAT RATE.** The human watched the real game: a held
direction **repeats**, *"at a medium pace… slow enough to see which item is
selected"*. That settles the existence half of H1 against our authored
one-step-per-deflection. Two numbers, and the port will not move without
them: the **initial delay** before the first repeat, and the **repeat
interval** after it. Frames between cursor moves at a stated present rate — a
count, not a stopwatch. Also: does the d-pad differ from the stick? Does it
accelerate while held, or stay flat?
2. **F2 — IS THE AUDIO MIX ON THE DISC?** The SFX are too loud and there is **no
gain value anywhere** in the export; `confirm` peaks at −0.0 dBFS and sits
3 dB above the music in mean. A cue record commonly carries a volume beside
its wave index, and you already decoded `sub_821C5580` playing cue 1103. If
per-cue or per-bus gain is there it is **decoded** and nobody has to choose.
If it provably is not, say so with reach.
3. **F3 — WHAT DOES THE TITLE PLAY?** A human says something is missing there.
Which cue, if any, does the title screen play, and is there a **sting** when
the plate appears or when Ⓐ is accepted? ⚠️ A negative needs a positive
control (R4): show the method finding the *menu's* cue before concluding the
title has none.
4. **F4 — WHAT DOES Ⓐ DO TO THE CLOCK?** In the real game, Ⓐ during the title
build-in **reveals the plate immediately** — so the boot takes three presses:
skip video, reveal plate, accept plate.
🔴 **This is a test of `clock: "shared"`.** The title is two composited builds
— build 4 the artwork (finishes `t≈118`), build 2/3 the plate (full alpha
`t=236`) — and the port's `authored/flow.json` runs them on **one** clock
started together. That premise is **authored**, and the port's own
`plate-arrival-halves.md` calls it *"not falsified… not confirmed to better
than ~20 %"*, with an unresolved anchor disagreement inside one binary
(`t=118` from the reconciliation, `160` from `settle_time()`).
The discriminator is observable: **press Ⓐ early, while the wordmark is still
building in, and watch the ARTWORK, not the plate.**
| if Ⓐ … | the artwork |
|---|---|
| advances the shared clock | **snaps** to finished |
| only forces the plate visible | **keeps animating** its remaining build-in |
📌 It is also a **cheap second route to the plate-arrival question** — a press
that skips to the plate says where the game thinks the plate belongs — and a
third input the boot title accepts, narrowing `REFUTED.md`'s *"any title after
the first refuses input"* further.
⚠️ Deliver a **series, not a settled value** — see
[`TEMPORAL-VERIFICATION.md`](TEMPORAL-VERIFICATION.md), and note that the port's
whole defect was invisible to three instruments that each measured a pose or a
throughput rather than a change.
## Previous sole focus, 2026-09-02 — the order, kept for the method
A human on real hardware: *"the logos just switch, there is no animation."*
Measured from a real boot — **the splash moves 1.30 s of 7.95 s (16.4 %)**, the
publisher logo frozen **3.20 s**, and the whole thing takes **26 distinct luma
states**. The port draws the right quads in the right places and never moves
them.
Your half is not the port's bug. It is that **nobody can say what the game does
between keyframes**, so nobody can say what the port should be doing.
### The deliverable, in the human's words
> *"Get the whole graphics pipeline, from the xex/pe + the disc files to the
> final screen displayed. Take Xenia Canary processing into account too."*
One continuous account, each stage carrying its evidence and its `⟨instrument⟩`:
```
disc bytes → RATC/T8aD decode → what the GAME CODE does per frame
→ the draw calls it submits → Canary's own processing
→ the presented frame
```
Three questions that are load-bearing and none answerable from a file alone:
1. **The per-frame update.** Which function advances a UI group's clock, in what
units, and **what does it do BETWEEN keyframes** — interpolate, or hold to the
next key? That single answer decides whether the port should lerp at all. It
is in the image. Find it.
2. **What is submitted per frame during the splash** — the draw list frame by
frame, not one settled frame. If alpha changes it changes *somewhere*
observable: a vertex colour, a PS constant, a blend factor, a texture swap.
**Name which, and give the per-frame series.**
3. **What Canary does to it** — present cadence, and any resolve, scale or gamma
between the guest's draw and the pixels a capture records. A capture is
evidence about *Canary's output*; the gap between that and the guest's intent
has bitten this corpus before (`kernel_display_gamma_type`).
⚠️ **Deliver a SERIES, not a settled value.** Follow
[`TEMPORAL-VERIFICATION.md`](TEMPORAL-VERIFICATION.md): film it, align by
content, report ordering and counts and durations. The port needs the alpha
*trajectory*; a single frame cannot carry one.
[`../../tools/motion-census`](../../tools/motion-census) measures change and
nothing else — use it on your own captures too, and note that three of the
port's instruments passed a frozen screen because each measured throughput or a
pose rather than change.
## Previous focus, 2026-09-01 (still live, but AFTER the above)
A human played the port on real hardware and reported that the splashes are
**close but not right** — the fade/blur is more pronounced in the game — and that
the `PRESS Ⓐ` plate arrives late. Read
[`PLAYTEST-2026-09-01.md`](PLAYTEST-2026-09-01.md) first; it has the findings and
why none of our checks caught them.
Their verdict on how we have been working is the part that matters:
> *"It seems the agents were essentially guessing and trying to copy what one
> would see, but while they did get close it still is not quite right."*
**So do not fit a curve to a screenshot. Find the mechanism.** For the splashes,
in this order, and answer each with evidence rather than by inference:
1. **Is there a post-process pass at all?** A blur, a bloom, a fade quad, a tone
curve, a resolve-and-resample. Yes/no, from GPU state.
2. **If yes: what is it?** How many passes, which render targets, what blend
state, which shaders (you have their hashes in the draw log already).
3. **Where do its parameters come from?** Immediate constants in the command
stream, PS/VS constant banks, a table in a pak, a computed ramp in code.
4. **Only then, what curve** — and it should fall out of 3, not be fitted.
Use **both** routes and say which produced each fact:
* **Dynamic** — Canary. Per-draw capture, shader constants, render-target
bindings, blend state, and where those are not logged, **add the logging**:
`/canary` is yours read-write and the draw logger already exists. Guest memory
and CPU state are available too; the splash's driver is a `GamePart` and its
parameters are somewhere in it.
* **Static** — the `.pe` image, `sylpheed.db`, the paks. The code that *sets up*
the pass is in the image, its constants may be immediates, and shader blobs
ship on the disc. A mechanism confirmed statically **generalises to every
screen**; one observed in a capture holds for that capture.
A mechanism found this way is *decoded* and cannot be "close". A curve fitted by
eye is neither.
⚠️ Anything you conclude about *timing* here must obey
[`TEMPORAL-VERIFICATION.md`](TEMPORAL-VERIFICATION.md). The plate-late finding is
a timing question and the corpus has already lost four claims to the wall clock.
### Second, and not optional: the complete input set
The port had **no joypad binding for Ⓐ or Ⓑ** and nobody noticed for a whole
milestone. The port has fixed its side. Yours is the other half:
**Decode what the game actually reads.** Every button, both sticks, the triggers,
START and BACK — per screen if it differs. The pad read path is in the image and
`sub_821CC860`'s decoded arguments already include `PAD`. Deliver the *set*, and
say for each entry whether it is decoded from the image, measured in a capture,
or neither. Guessing which buttons exist by pressing them is how we got here.
`BLOCKED.md` is frozen. Do not add rows. Open issues instead.
## Your objective
`docs/port/MISSION.md` — read it every iteration. It lists the open questions and
the gate each must pass.
You own **the disc → meaning**: formats, tables, the corpus, `sylpheed-formats`.
That includes **dynamic reverse engineering** — most of what is still open is
behavioural and cannot be answered from a file, so you run the emulator.
**The Port cannot answer anything.** It has no emulator and no oracle, so
whatever you leave unanswered it will either author by hand or guess — and a
guess of theirs is indistinguishable from a fact a week later. Prefer the
question that unblocks them earliest and whose first step is cheapest.
You do **not** build the port. If you find yourself writing GDScript or designing
an export schema, stop and go back to the question you were answering.
## The oracle
## Before anything else, every iteration: sync with `main`
**The real game, running in Xenia Canary, captured.** Not `sylpheed-cli`, not the
Explorer, not any renderer of ours — those are tools for verifying our decoding,
they are hypotheses under test, and they have been wrong. A claim resting on our
renderer is a claim about our renderer.
```bash
git -C /work fetch origin && git -C /work merge --no-edit origin/main
```
🔴 **On your FIRST iteration after 2026-09-01, also merge the human's branch:**
```bash
git -C /work merge --no-edit origin/human/r1-register-reclassification
```
It carries the **R1 reclassification of `REFUTED.md`** (every entry now names its
`⟨instrument⟩`; ten moved ❌ → 🟡), R1 as standing text in `PROTOCOL.md`, and
`tools/stale-instrument`. It branches from `auto/frame-blend-draw-path`, so if
you are on that line it is a fast-forward. **Two of the ten re-opened entries
land on this iteration's focus** — do not start the splashes without reading
them.
You work on a topic branch, and you read the protocol, the mission and the
shared tooling **from your own checkout** — so without this you are following
whichever version of the rules existed when your branch started. That is not
hypothetical: `tools/audio-capture` and two protocol revisions landed on `main`
while one agent worked for hours from a branch that had neither.
If the merge conflicts, resolve it, say so in your reply, and carry on.
## Read these first, every iteration
1. `docs/agents/PROTOCOL.md` — how this team works. Non-negotiable.
2. `docs/port/MISSION.md` — the open questions and their gates.
3. `docs/port/HANDOFF.md` — what the port has been told. **Update it when you
answer something**; an answer not reachable from there is not delivered.
4. `docs/re/REFUTED.md` — already tested and dead. Grep it for your nouns.
5. `docs/re/METHOD.md` — traps this corpus has already paid for.
6. `docs/re/INDEX.md` — what is decoded. Re-deriving a ✅ row is not a finding.
7. `docs/game/navigation.md` — how the game is navigated, **from the player's
side**. Fill it in as you go: you are the one who sees the real screens.
8. `docs/agents/CONTAINER-NOTES.md` — the container's tooling, and the reference
assets described below.
9. `docs/agents/TEMPORAL-VERIFICATION.md` — **how to verify anything that
moves.** Set by the human. Every temporal claim must obey it.
10. `docs/agents/PLAYTEST-2026-09-01.md` — what a human found playing the port.
⚠️ **`REFUTED.md` was reclassified by the human on 2026-09-01 under rule R1.**
Every entry now ends with its `⟨instrument⟩`, and **ten entries moved ❌ → 🟡**
because the instrument that killed them was one of ours. A 🟡 is *not* dead — it
is re-openable, and each says what would settle it. Read the file's own "How to
read this file" section once. When you improve a renderer, a reader or the
capture harness, run `tools/stale-instrument <that instrument>`: it lists exactly
what that instrument killed, so those claims re-open instead of staying dead
because nobody remembered which ones rested on it.
🔴 Two of the ten bear directly on the current focus. *"The declared keyframe
timeline reproduces the captured splash"* is now 🟡 `⟨our-reader⟩`, never
re-derived under the record-layout fix. And the **`rest()` pair** is open in
**both** directions — both legs run through our renderer — and the two splashes
are the only screens that reach that fallback.
**Rule R1 follows from that.** A refutation whose instrument is one of our own
renderers is not a refutation — it is *"our renderer disagrees"*: 🟡, not ❌.
Entries in `REFUTED.md` name their `⟨instrument⟩`, and `tools/stale-instrument`
lists everything a given instrument killed, so those re-open when it improves.

## 🔴🔴 SOLE FOCUS, 2026-09-02: **THE TITLE'S ANIMATION TIMING — F5 and F6, nothing else**
You have no emulator and no oracle, so **a guess of yours is indistinguishable
from a fact and will be believed later.** When you need to know what the game
does, open a `kind/ask` issue for the Decoder.
**Work only these.** Not the repeat rate, not the audio mix, not P7 — they stay
queued in
[`../agents/PLAYTEST-2026-09-02-menus.md`](../agents/PLAYTEST-2026-09-02-menus.md).
## 🔴 The working surface changed on 2026-09-04. Read this before anything else.
> *"Let's have the agents focus on this item and only this only."*
**Work is tracked in Gitea issues, not in `BLOCKED.md`. Changes reach `main`
through pull requests, not by a human merging your branch.** The rules are in
[`PROTOCOL.md`](PROTOCOL.md) — the *Work items*, *Messages*, *Pull requests* and
*Each iteration* sections are all new. Read them.
**F6 — the title's sweeping white glow starts too early here.** A human watching
the real game reports that the glow travelling along the blue PCB-like lines
(**`ptloop01` / `ptloop02`**) **only begins when the plate appears**; the port
starts it before. **This is the Decoder's to establish and yours to implement** —
do not choose a start time. What you *can* do now without an answer: determine
exactly **what your renderer currently uses** to start that sweep, so that when
the answer lands the change is one line and not an investigation.
Three things that will bite you if you skim:
**F5 — does Ⓐ snap or accelerate the title?** The Decoder is measuring it. Until
they answer, **do not implement Ⓐ#2** — a snap and a speed-up are different
behaviours and picking one is exactly the guessing that has cost this project.
1. **Nothing pushes to you.** Notifications are polled. Read them at the top of
every iteration or nothing addressed to you ever arrives.
2. **Never wait on an ask.** Set the dependency edge, take the next item.
3. **You cannot close your own work.** You move an item to `state/needs-human`
with a one-line "look at this, pass looks like X". The human closes it.
### And split it before you start
`BLOCKED.md` is frozen. Do not add rows. Open issues instead; migrate a row only
when you actually work it.
**Read the new "Work in units a human can check in a minute" section of
[`PROTOCOL.md`](PROTOCOL.md).** The human's diagnosis is that whole missions have
been too big to hold — the splash sat through a milestone, then took a day once
scoped to *does it animate?*. Break the work down, write the question and what
the human should look at **before** working, do one unit, hand it over, and stop.
Do not stack a second change on an unverified first.
## What landed on `main` on 2026-09-04, and what did not
## ✅ THE LOGO SPLASHES ARE DONE — signed off by the human, 2026-09-02
The human took **only the play-tested work** off `auto/port-p6-audio` — up to
`77320d5e`, source paths only. On `main` now: the splash animation fix, gamepad
input, menu navigation and flow, menu audio, the exporter, `authored/`, and the
23 tools under `tools/port/`.
> *"Looks good! Cannot notice any obvious difference from the actual game.
> Mark logos as done."*
**Deliberately left behind, and each is an issue now, not a lost cause:**
**The sole-focus order is lifted. Return to your milestones.** The fix was
`pose_at` assigning the settle instant instead of clamping to it — and that same
line manufactured the false green, because the capture harness was photographing
t ≈ 2 units and it *looked* settled only because everything did.
* the **F5/F6 title-timing work** after `c0ae460a`. Its own tip commit calls
itself a hand-off for human checks — so it goes through the gate like anything
else. **Do not re-derive it. Re-propose it**, as a PR, in checkable pieces.
* the **OPTIONS menu work** of 2026-09-03. Real, probably good, never play-tested.
* the **F1 repeat mechanism**, which its own commit calls *"deliberately inert"*.
📌 **Keep the lesson, it outlives the bug.** Three instruments passed a frozen
screen: a frozen sweep drives the clock by hand, a settled comparison is
*defined* to pass on a frozen screen, and an achieved-fps counter counts frames
drawn rather than frames different. Ask of any new check: **what would this still
report if the feature were entirely absent?** `tools/motion-census` exists for
exactly that question; keep it in `check-all`.
🔴 **545 MB of extracted game content was committed on that branch** — 850
sprite, audio and transcoded video files under `export-probe/` and
`export-probe2/`, plus 246 MB of loose `.wav` at the repo root. None of it
reached `main`. The rule against this was live *and had just been tightened by
you*, with a careful comment about listing both `export/` and `data/base/` —
while the exporter wrote to a third name. **Enumerating names is what failed.**
`.gitignore` now describes the shape. The lesson generalises past `.gitignore`:
a rule that lists instances does not cover the class.
## ✅ P5's GATE IS MET — the human walked it, 2026-09-02
## The durable lessons — these outlive the bugs that produced them
> *"Menu walk and navigation is fine. Video skips too. Extras open. New Game
> shows new game intro video."*
**Ask of any check: what would this still report if the feature were entirely
absent?**
`PORT-MISSION.md` is updated. The NEW GAME gap is accepted as-is — they know the
difficulty select comes first in the real game and that the port announces it.
Three instruments passed a splash that never animated at all. A frozen sweep
drives the clock by hand, so it proves the renderer can draw pose *N* and never
that poses advance. A settled comparison is *defined* to pass on a frozen screen.
An achieved-fps counter counts frames **drawn**, so drawing identical pixels 25×/s
scores like animating. Every one measured throughput or a pose; **none measured
change.** [`tools/motion-census`](../../tools/motion-census) exists for exactly
that question and stays in `check-all`.
### 🔴 Four findings from the same session — read [`../agents/PLAYTEST-2026-09-02-menus.md`](../agents/PLAYTEST-2026-09-02-menus.md)
**The instrument must sit at or above the thing that can break.** `--script`
sends `InputEventAction`, which **bypasses the input map** — so every input check
asserted the code *below* the map and nothing about the map itself, while Ⓐ was
dead on real hardware for an entire milestone. Synthetic input is not a test of
input.
| | | yours to do |
|---|---|---|
| **F1** | **The menu REPEATS on a held direction. Ours does not.** One step per deflection was authored as the safe choice; the human has now watched the real game and it repeats. | **Implement the mechanism. 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. |
| **F2** | **SFX too loud, and there is no mix at all.** Measured: `confirm` −17.7 dB mean / **−0.0 dB peak**, 3 dB hotter than the music; no gain value exists anywhere in `export/` or `authored/`. | Add gains **at playback, as data** — a bus per kind. ⚠️ **Do NOT normalise in the exporter**: re-levelling destroys the relationship between clips and a modder cannot undo it. The Decoder is checking whether the mix is on the disc. |
| **F3** | **Something is missing on the title screen** — a track or a sting. The export has one music file and the port plays nothing on the title. | Wait for the Decoder; nothing to author yet. |
| **F4** | **Ⓐ skips FORWARD through the boot, and we implement two of three presses.** Ⓐ#1 skips the video ✅, **Ⓐ#2 reveals the plate immediately ❌ missing**, Ⓐ#3 activates it ✅. | Make Ⓐ during the title build-in jump to the plate — but **do not choose what "jump" means.** 🔴 It is a **test of `clock: "shared"`**, which is authored and, in your own words, *"not confirmed to better than ~20 %"*. If Ⓐ advances the shared clock the artwork **snaps**; if it only forces the plate visible the artwork **keeps animating**. Those look different on an early press, so the oracle can settle it. **Answer it before building on `shared`.** (Correction: an earlier draft of this brief said "both clocks" — there is only ONE, and hunting for a second would waste an iteration.) |

**H3, the plate delay, is ACCEPTED** — *"feels the same… sufficient"*. Stop
working on it. Leave the row unattributed rather than closing it green.
**Rule R1, on the register.** A refutation whose instrument is one of our own
renderers is not a refutation — it is *"our renderer disagrees"*: 🟡, not ❌.
Entries in `REFUTED.md` name their `⟨instrument⟩`; `tools/stale-instrument` lists
what a given instrument killed, so those re-open when it improves. Grep
`REFUTED.md` before proposing anything.
## Previous sole focus, 2026-09-02 — RESOLVED, kept for the method
## Read these every iteration
> *"The port does no blur animation at all. The logos just switch."*
Measured from a real boot, not paraphrased: **the splash moves 1.30 s of 7.95 s
(16.4 %)**, the publisher logo is **frozen for 3.20 s**, the developer logo for
2.40 s, and the whole 7.95 s takes **26 distinct luma states**. A 45-unit
build-in cannot be drawn in 26 states.
🔴 **Your three instruments all passed this, and the reason is the point:**
* the **frozen sweep** drives the clock by hand — it proves the renderer can
draw pose *N*, never that the poses are drawn in sequence while running;
* the **settled comparison** scored 0.01 % — a screen frozen 84 % of the time
matches a settled reference *perfectly*, because that is what frozen means;
* the **achieved-fps counter** counts frames DRAWN — drawing the same pixels
25×/s scores exactly like animating.
**Every one measured throughput or a pose. None measured CHANGE.** Same shape as
`InputEventAction` bypassing the input map: the instrument sat below the thing
that was broken.
**Use [`tools/motion-census`](../../tools/motion-census)** — it measures change
and nothing else, and its `--selftest` proves it separates a fade from a switch
from a frozen film. Order of work:
1. **Reproduce first**, with `--film` + `motion-census`, and quote the numbers.
If you do not get ~16 %, that disagreement is the finding — say so.
2. **Find why the poses do not advance.** Unranked, none established:
interpolation returning one pose across a range of *t*; `rest()`/plateau
snapping to an endpoint; the group clock not integrating; nearest-keyframe
instead of lerp; advancing by keyframe *index* rather than by time.
3. **Every fix is gated by a FILM, never a still.** A change that improves a
settled frame and leaves the film at 16 % has not fixed this.
4. Put `motion-census` in `check-all` so the regression fails a check instead of
waiting for a human.
⚠️ **And record the refutation against yourself.** `BLOCKED.md` H2 reads ✅
ANSWERED on the strength of the frozen sweep. The *mechanism* half stands — the
blur is a baked companion texture, decoded and correct. The *behaviour* half does
not: you draw those quads and do not animate them, so "the companions are drawn"
was true and did not mean what the row used it to mean.
## Previous focus, 2026-09-01 (still live, but AFTER the above)
A human played this port on a real controller for the first time. Read
[`../agents/PLAYTEST-2026-09-01.md`](../agents/PLAYTEST-2026-09-01.md) **before
anything else** — it has all four findings and, more importantly, why none of
your checks caught two of them.
**Two were fixed for you by the human. Do not re-do them; do read them.**
1. **Ⓐ and Ⓑ were never bound to the pad.** 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`. Ⓐ was dead on real hardware for the whole of P5 while your
unattended walk passed every iteration. Fixed in `port/scripts/gamepad.gd`;
asserted by `tools/port/verify-input`, now in `check-all`.
2. **The left stick fired once per jitter.** An axis is not an edge. Latched to
one step per deflection, with hysteresis.

**Two are open and are your focus:**
3. **The `PRESS Ⓐ` plate arrives late.** You raise it at `t=236`, derived as
`238 − 118 = 120 units = 2.000 s`. A human watching both says late. The
unit→seconds conversion is load-bearing and is exactly what the wall clock
cannot be trusted for. **This is an RE question if the cause is the unit; it
is yours if the cause is the clock origin or `rest.t`.** Establish which
half it is before asking, and say how you established it.
4. **The splash fade/blur is not the game's** — the game's is more pronounced.
You apply **no blur at all**. Whether the game runs a post-process pass is an
oracle question and it is with the Decoder. **Do not fit a curve to a
screenshot while waiting** — that is exactly what produced "close but not
right".
⚠️ Anything you conclude about timing must obey
[`../agents/TEMPORAL-VERIFICATION.md`](../agents/TEMPORAL-VERIFICATION.md).
Record a film and align by content; never compare at an absolute time.
⚠️ **`REFUTED.md` was reclassified by the human on 2026-09-01 (rule R1).** Ten
entries moved ❌ → 🟡 because our own renderer or reader killed them. Two bear on
your focus: *"the declared keyframe timeline reproduces the captured splash"* is
now 🟡 `⟨our-reader⟩`, and the **`rest()` pair is open in both directions** — and
the two splashes are the **only** screens reaching that fallback.
## Your objective
`docs/port/PORT-MISSION.md` — read it every iteration. Milestones P0…P7, each
gated by an **artifact**, never by "it compiles".
You own **the disc → playable**: `crates/sylpheed-export`, `port/`, the asset
tree. You do **not** reverse engineer. You have no emulator and no oracle, so a
guess of yours is indistinguishable from a fact and will be believed later.
## Before anything else, every iteration: sync with `main`
```bash
git -C /work fetch origin && git -C /work merge --no-edit origin/main
```
🔴 **On your FIRST iteration after 2026-09-01, also merge the human's branch:**
```bash
git -C /work merge --no-edit origin/human/r1-retro-tick
```
It carries **the two input fixes made for you** (`port/scripts/gamepad.gd`,
`tools/port/verify-input` + its control, wired into `check-all`), the new
`BLOCKED.md` rows **H1–H3**, and the retro tick. It branches from
`auto/port-p6-audio`, so on that line it is a fast-forward. **Merge it before
touching input**, or you will re-derive a fix that is already written and
asserted.
You work on a topic branch, and you read the protocol, the mission and the
shared tooling **from your own checkout** — so without this you are following
whichever version of the rules existed when your branch started. That is not
hypothetical: `tools/audio-capture` and two protocol revisions landed on `main`
while one agent worked for hours from a branch that had neither.
If the merge conflicts, resolve it, say so in your reply, and carry on.
