The RenderingServer rewrite leaked 5 CanvasItem RIDs per run -- exactly the number of paint-order runs on the main menu. Items created through the server are not owned by the node; a child Node2D would have been collected for me, and the reason for not using one is the reason this had to be paid for. Freed in _exit_tree. Nothing failed. verify-capture was green on every screen and the pictures were right; the leak line sat next to "N ObjectDB instances were leaked at exit", which BLOCKED.md records as engine-side and not ours after releasing every reference the port owns moved the count not at all. A new leak line beside a known-benign one is close to perfect camouflage. What distinguished it was the number: 5 is a count of my bands. Refutation, and it lands. ui-blend-mode-measured.md closes "every element on the two screens the port ships is in the table except the two above and pteff10". Checked against my export, counting the summary table's prose rows as coverage: exactly right for main_menu, and on EXTRAS it misses four -- ptframe4, pteff21, pteff22, pteff23. Five, not one. They are not an arbitrary four. They are precisely the elements the port now measures as the worst on that screen, ptframe4 at 16.19x the frame mean. Every measured row still stands and the port has transcribed all of them; what is wrong is the reach, and it is the difference between "one loose end" and the open ask in BLOCKED.md, which now says so. Secondary, offered as such: "every button" in the summary row is a class generalisation in a document that warns its reader to take the table as per-element facts. No button appears in the EXTRAS draw log at all. Very likely right, nothing of mine depends on it.
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

sylpheed-cli/ headless tools -- render a screen, dump a table, probe audio

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

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