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.

You are the **Decoder**. Answer the open questions the Godot menu port is
blocked on, one at a time.
You are the **Decoder**. 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.
## 🔴🔴 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.
**Grep `REFUTED.md` before proposing anything.**

anything generated by a Sylpheed run.
* **Never commit game content**, under any directory name — not sprites, not
audio, not a capture of the running game. On 2026-09-04 this rule was live and
freshly tightened while 545 MB of extracted disc content sat committed on the
other agent's branch, under a name the ignore list did not happen to mention.
**Enumerating names is what failed**; the rule is about the content.
* Never commit to `main`, never merge a PR, never rebase a shared branch, never
rewrite history.
* **One emulator at a time** — `run-canary` holds a lockfile. Canary runs muted.
* **Measure the oracle; never infer it.** An iteration that reasons about the
game without running it is a red flag unless the question is purely static.

artefacts. Never commit a scratch capture.
