From the Decoder's audit of their own /canary checkout, not from anything visible on this side. They applied their own lesson rather than stating it, and the exposure was four logger commits deep, not one. The sharpest bears directly on what this port shipped. `0f920e645` adds `blend=` per draw, and without it a draw log records NO BLEND STATE AT ALL -- so ui-blend-mode-decoded.md's 35-element oracle, the evidence on which this port DELETED its authored additive map, could not be re-derived by anyone who cloned this repository. Not approximately. Not at all. It is reproducible now: four container-only commits exported as patches on their branch with a rebuild recipe. Named in prose without a resolvable path, since that directory is not in this checkout and citing it as one would be the exact defect check-citations exists to catch. What it changes: nothing is retracted. The measurement was real when made and is now portable, and the trade was still right -- a screen-name map cannot answer for a screen nobody drove to, so the decoded field is better regardless. What it changes is what "decoded" was resting on: for the window between adoption and export, this port had deleted an authored entry in favour of a field whose supporting oracle nobody else could regenerate. 📌 Theirs, and the durable line: a finding is only as portable as the tool that produced it, and a reproduce recipe that READS as complete is the dangerous kind. Theirs named shas, which is why four commits sat unexported while one was noticed. ⚠️ And this port cannot check the class from here. check-citations scans repo paths; an instrument living in another container is not a path at all. The only defence available on this side is asking what produced a number before adopting it -- which is a habit, not a check, and does not run.

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

Xenia Canary is a separate repository: it is a fork tracking upstream, and it carries our instrumentation.
