Two results and one retraction, all from the same session. REFUTED: 'an ~8-10 s idle returns to the title' does not apply to the main menu. Held untouched it stayed put for >= 60 s, correlation never leaving 0.9245-0.9249. That timer is real but belongs to the TITLE. It was the only reason 'B leaves the main menu' was classed as authored, so Q5's B rule is upgraded to measured-ordering: B is delivered (canary logs vk=5801) and is the only input in >= 100 s before the return. The PRESS (A) plate: the boot title presents build 4 WITHOUT the plate first -- green-glyph 154, against 159 on the committed no-plate capture and 753/977/1493 on plate titles -- and the plate arrives after. That is the port's third option. RETRACTED: four durations taken the same day. classify_array costs 1503 ms per frame; running it per frame against an 8 fps x11grab drained the pipe at 0.64 fps, so every classified frame was stale and increasingly so. It manufactured 'plate 24.66 s after the title art', 'B->title 15.58 s', 'B->title 25.60 s' and 'A->menu 20.26 s'. The tell: a transition, a press and a fade do not share a duration, and the two B figures GREW across a longer run. A backlog preserves ordering and destroys durations, which is why the sequence results above stand and every timing does not. The ring's period is unaffected and that was checked, not assumed -- ring_period ran at 15.03 fps against a requested 15.

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.

Confidence is per claim, never per document: ✅ CONFIRMED · 🟡 PROBABLE ·

rather than deleted — that is why the numbers here can be trusted.
