sylpheed-port found P0 complete-but-unindexed: the work existed, the artifact existed, the gate record did not. They named it as the argued-versus-indexed split one level up from the refutation register, which is a shape worth checking on my own objective rather than only agreeing with. MISSION's gate has two halves -- "a written docs/re/ result with the evidence, and reference data committed alongside it" -- and all ten questions read answered. Half one: all ten cite a docs/re/ result. Half two: every data/ and captures/ path those nine pages cite was resolved against the tree. 48 citations, 0 missing. Spot-checked six for substance rather than existence, since the gate's PURPOSE is that the port can work without a disc -- 1.2 KB to 20.7 KB, 15 to 324 numeric lines each. No stubs. CLEAN, and unlike the port's P0 also indexed: HANDOFF's status table cites the page and the page cites the data. Reach stated, because a clean audit is worth exactly its checks. This tests that CITED files EXIST and carry content. It does not test that the data supports the claim, and it cannot see data a page should have cited and did not -- a page citing nothing would have passed as "0 missing". None did, but the check would not have caught it. Existence and substance, never sufficiency.

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-cliand 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
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
docs/re/INDEX.md— what is decodeddocs/re/REFUTED.md— what has been tested and dieddocs/re/METHOD.md— traps this project has already paid fordocs/game/navigation.md— how the game is navigateddocs/port/MODDING.md— why the asset tree looks the way it does
Xenia Canary is a separate repository: it is a fork tracking upstream, and it carries our instrumentation.
Conventions
Confidence is per claim, never per document: ✅ CONFIRMED · 🟡 PROBABLE ·
❔ HYPOTHESIS · ❌ REFUTED. A withdrawn result is kept with its reasoning
rather than deleted — that is why the numbers here can be trusted.
