Sylpheed port agent 33ab07ff2e port: finish the required-reading audit -- MODDING clean and checker-backed
Finished the second half rather than leaving it named. MODDING.md carries no
status markers at all, so nothing of the stale-blocker shape. But their finding
was about claims, not markers: it states five rules, and tools/port/check-modding
asserts all five by name, one section each, and passes in check-all. Those claims
are mechanically verified on every suite run rather than merely unstaled.

Of the five documents the brief names, three are mine: BLOCKED.md (five rows
struck earlier), PORT-MISSION.md (two stale blockers corrected), MODDING.md
(clean, checker-backed). PROTOCOL.md and HANDOFF.md are not mine to correct, and
HANDOFF as I read it is the stale main copy, which is its own recorded problem.

Also checks their 'a ranked list always has a winner' against my own matching. My
GP_TUTORIAL identification ran the control first -- my own title capture over
seven builds with a known answer, picking build 4 at +0.2792 -- and the submenu
then scored +0.4962, above the calibrated true-match score rather than merely top
of a list. No other nearest-match report exists in the tree.

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-cli and 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.
