sylph-decoder 4ac5c9f419 ci: install the clippy component the Clippy step needs
`dtolnay/rust-toolchain@stable` installs a minimal profile. The `native`
job named no components, so every run that reached the Clippy step died
on

    error: 'cargo-clippy' is not installed for the toolchain
           'stable-aarch64-unknown-linux-gnu'

before clippy read a line of source. That is not a lint result; the step
had never run. The `fmt` job below always named `components: rustfmt`
correctly — this one never did.

Two lines of behaviour change. The rest is the comment explaining why the
step is left gating on `-D warnings` rather than softened: the workspace
is not clippy-clean (run 203's build alone emits ~13 rustc warnings that
`-D warnings` promotes to errors), and `continue-on-error` cannot tell
"debt not yet paid" from "debt paid". That debt is scoped in #13, the way
the rustfmt debt is in #12.

Run 203 is what made this visible. With the aarch64 fix in 64bb7da the
native job got all the way through:

    cargo check  --workspace   ok  10m01s
    cargo build  --workspace   ok  19m04s
    cargo test   --workspace   ok  16m22s   214 passed, 0 failed
    cargo clippy --workspace   toolchain error

Refs #13

Sylpheed

A clean-room reverse engineering and port project for Project Sylpheed: Arc of Deception (Xbox 360, 2007).

Three things live here, in one repository so that a change spanning them lands as one commit:

The decoders crates/sylpheed-formats — the disc's formats, read and verified disc-wide
The port port/ — a Godot 4 project, plus crates/sylpheed-export which converts a disc into the open asset tree it reads
The corpus docs/re/ — what has been reverse engineered, with its evidence, its retractions and its dead ends

You need your own copy of the game. No game content is in this repository and none ever will be. The exporter reads the disc you supply.

The oracle is the real game

sylpheed-cli and the Explorer are tools for verifying our decoding. They are hypotheses under test and they have been wrong. When something must be checked against the truth, the truth is the game running in Xenia Canary, captured — not any renderer of ours.

This is stated first because getting it backwards is the most expensive mistake this project has made.

Layout

crates/
  sylpheed-formats/   the decoders. Disc-wide verified; the corpus is its spec
  sylpheed-cli/       headless tools -- render a screen, dump a table, probe audio
  sylpheed-viewer/    the Explorer: a human's window onto the disc. STATIC data only
  sylpheed-export/    disc -> the open, moddable asset tree
port/                 the Godot 4 project. Reads open formats ONLY
authored/             decisions that are NOT on the disc, each with its reason
data/
  base/               generated by the exporter. Gitignored, never hand-edited
  mods/               drop-in overrides. Yours
docs/
  re/                 the corpus: findings, refutations, method traps
  game/               how the game is navigated -- menus, modals, flight
  port/               the port's mission, its handoff contract, modding rules
                      -- and RUNNING.md, which is how you actually start it
  agents/             how the agent team works together
tools/                capture harnesses, probes, the share tool
exchange/             transient inter-agent files. NOT in git
docker/               the agent containers

Where to start

Xenia Canary is a separate repository: it is a fork tracking upstream, and it carries our instrumentation.
