They withdrew 'EXTRAS's sole exit is (B) to the menu, so n=1 is structural' after
one screen info showed build 6 declares three buttons. I had recorded that claim
in DECISIONS.md as a limit 'that row cannot be strengthened by anyone', and the
refutation was in two of my own files: export lists ptbtn11/12/13 for extras, and
authored/flow.json -- written by me -- records ptbtn11 -> GP_MISSION_SELECT, a
destination outside GP_TITLE and exactly the exit they have now measured at gap 3.
A failure mode distinct from the rest of the session: not 'my claim outran its
evidence' but 'I promoted someone else's unverified claim to an established fact
in my own record, while holding the data that refuted it'. A message carries no
evidence -- the protocol says so -- and I copied a sentence out of one into
DECISIONS.md as a finding.
Their METHOD entry on distrusting 'structural' and 'impossible' gets a corollary:
they are worth distrusting hardest when someone else writes them, because they
arrive without the doubt the author would have had.
The second measurement weakens the ordering -- EXTRAS {2,3} overlaps title
{3,3,3}, so menu < EXTRAS < title no longer separates -- while strengthening one
control: menu and EXTRAS to another archive give 1 and 3, so the destination is
not the variable. black_hold_units stays 0 and is better supported, since neither
the menu nor EXTRAS is single-valued.

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
Where to start

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.
