tools/port/audit-kinds reports what each in authored/ rests on. Nothing had ever checked them, which is the point -- the disciplines that fail this way are the ones that never visibly failed. Seven of fifteen labels, every goto_name_kind, had no of their own. Four scored ok on the first run because the audit fell back to the parent's , which argues the DESTINATION while the label is about where the NAME came from. That is the same error I was corrected for the previous iteration, one level down: crediting a claim with evidence that does not bear on it. Borrowed evidence is now its own outcome, and all seven carry a why citing HANDOFF Q4's own words and stating that the port never branches on the field. The audit refuted itself twice first. It counted only paths, shas and filenames as citations, so HANDOFF Q1 and PORT-MISSION section 7 read as citing nothing -- four false positives, and an audit that invents defects is worse than none because its false positives are indistinguishable from its true ones until each is opened. It also resolved paths against committed refs only, failing on a citation to the tool being written. Both fixed. It still cannot read a cited page to confirm it says what the why claims, and prints that every run. MEASURED and measured both existed; a consumer comparing == measured misses the other, and a label that fails to match reads as ABSENT rather than wrong. Normalised. Refutation attempt on HANDOFF Q2's map of GP_TITLE. The headline survives and is exactly right: 4 UI states + 2 loading variants + 2 boot splashes = 8 states shipped twice = the 16 entries the archive holds, confirmed against my export's entry map. But the row enumerates six of those eight -- entries 10, 11, 13 and 14, publisher_logo and developer_logos, appear nowhere in it. A reader counting Q2 gets twelve, and this is the row already corrected once for an ordinal-versus- entry error, which is the mistake four unlisted entries feed. The port is unaffected; both splashes are exported, named and verified at RMSE 2.17 and 3.05. Every asserting check passes, audit-kinds included.

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.

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