Their generalisation of my 'untimed' marker -- search for the vocabulary the dead rule needed -- is the cheap version and it works. Swept for the nouns of every rule refuted this session. Two real hits: verify-screen:57 still asserting 'all four are COMPOSITED rather than standalone', the reading withdrawn after they tested it disc-wide at 7.9%; and boot.gd:197 opening with the pre-fix 'no time slot' claim before retracting it. Third and fourth instance after spin_period_units and exit_ramp_units, and in all four the correction sits below the false claim in the same block, with both written by me. The diagnosis is a habit: my corrections are ADDITIVE. I append a CORRECTION block and leave the original standing, which is right for a record and wrong for a statement -- a reader takes the first assertion and the retraction three lines later has already lost. The habit that creates these is the same one I adopted to make corrections honest. Fix: keep quoting the original but demote it grammatically, leading with 'what this used to say'. Both rewritten. Verified comment-only by artifact rather than by reading -- the main_menu render is byte-identical before and after. Also records agreement with their caution: the failed gap+clear rule was rejected, not narrowed to menu transitions.

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

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.
