verify-capture's main_menu row reads 13.30 / 13.27 / 13.25 / 13.26 across runs this session while every other row is identical to the digit. I cited those numbers repeatedly, including in the rest() adjudication. Cause: the focus ring spins on time_units raw rather than the pose clamped by holding -- deliberate and correct, since the ring is the one thing on a settled screen that keeps moving -- so its angle at capture is set by the wall clock. extras is stable because nothing there spins. --loop-phase already existed and did not cover it: it pins the looping focus record phase, while the spin is a second free-running clock I guarded once and never connected. Extended loop_phase_units to pin the spin too, and verify-capture now passes --loop-phase=0 at all four render sites. The control matters because the drift was intermittent -- three unpinned runs gave 13.25, 13.26, 13.26, so three pinned runs agreeing would prove nothing. Phases 0/30/60/90 give 13.2583 / 13.1991 / 13.2637 / 13.2588: the pin is live and the 0.065 spread is the whole of the observed drift. Non-finding recorded so nobody mines it: phase 30 scoring lowest is not evidence about the ring's real phase -- 0.065 against a ~13.2 gamma floor is 200x too small. A margin only means something against the noise it sits on. No conclusion changes: the smallest margin any of them turned on was 0.14% differing area.

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.
