Paused at six of eight phases, all committed and pushed, nothing left in a working tree. The page now carries a STATUS section the other machine can finish from: what is done, which PR each phase is in, what to run next, and what is deliberately left for the human. 🔴 FOUR THINGS THIS PAGE ASSERTED WERE WRONG, and each is corrected in place rather than quietly amended: * "10 dangling citations" was ONE. Eight were DIRECTORY references, which resolve and are absent only from `git ls-tree`; one was a path ending a sentence, with the full stop pulled into the match. I reported that 10 to the human twice. * `extract -r` is not how the .pe was made and nothing depends on it. The plain extract is, and the tool Phase 3 keeps reproduces it byte-for-byte. * The Phase 0 gate compared branches by SHA and called seven safe branches unpushed -- a branch that is an ancestor of a pushed one is preserved. * There is no DirectXShaderCompiler drift; the ' m' is nested submodule dirt. The pattern is worth more than the corrections: every claim that was REASONED turned out wrong, and every one that was RUN held. Phase 2's gate refuted its own premise, Phase 3's proved two alarming row deltas were an improvement, and Phase 4's check caught a deletion I had just made. The page now says to re-run the gates rather than trust the results recorded in it. Phase 5 (archive) and Phase 7 (drops) are open and marked NOT STARTED, with the reason each needs the human: archiving is reversible and deleting a repository is not, and the drops are on the human's disk.

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
-- 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
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.
