Extends the latency finding with a third point, and it changes the advice. xenia default (~5.3 ms) 347.5 s 39.3 percent silence 30.5 gaps/s 3.94 ms median PULSE_LATENCY_MSEC=200 88.0 s 15.6 percent silence 3.5 gaps/s 37.33 ms median PULSE_LATENCY_MSEC=500 87.9 s 50.1 percent silence 1.3 gaps/s 346.67 ms median 200 ms is 2.5x better than the default; 500 ms is worse than either. Raising the buffer keeps cutting the gap RATE while total silence bottoms out at 200 ms and then doubles, because an over-large buffer starves in a few enormous holes rather than many small ones. That is also a warning about the metric. The port s check-capture bar is 20 gaps/s, derived from sound controls -- starved 32.9, genuine music bed 3.3, voice track 0.03. The 500 ms file scores 1.3 gaps/s, better than a real music bed, while being 50 percent silence: a gap-rate test alone would pass the worst capture of the three. It needs a total-silence companion. Same shape as the defect that made a per-channel level table useless -- one number that cannot see the failure mode next door.

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.
