Adds examples/element_records.rs, which lists leaf AND focus_link records for an element, plus a disc-wide census. Built because I claimed alpha 80 was undeclared after reading one of ptbtn00's two records -- and focus_link was already parsed, with ui_layout.rs:424 already documenting the focus record. The format was known and I did not consult it. Census: 1467 of 15493 elements (9.5%) across 815 builds carry a second record whose keyframes are invisible to a by-name leaf lookup. Refutes our own parser's description of the field. It is documented as "the focused state of a button", but GP_TITLE has pgloading_loop1 -> loop3 -> loop4, a chain of three loop animations, and ptloop01 -> ptloop02, the two sweeps. Neither is a focused state. Naming defect only -- behaviour is right where it is read -- so not renamed here. 🟡 Notes a better candidate for why the two sweeps share one indices=8 draw: they are linked, not merely co-textured. Testable on the pgloading chain, which needs a loading-screen capture I do not have. Named, not claimed.

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.
