Sylpheed port agent d1a1633619 port: assert the scan boundary I had hand-verified, and give audit-kinds a self-test
check-claims --control plants a revival in docs/port/ and requires exit 1. That
the plant lands INSIDE a scanned directory was a property I checked manually, one
time, and wrote up -- the exact pattern I had criticised in this same tool one
iteration earlier. A fifth case now plants the identical text OUTSIDE the scanned
root and requires 0, so the pair asserts the boundary is real: same text, 1 inside
and 0 outside. Either half alone is consistent with the tool scanning everything,
or nothing. Five cases: clean 0, unmarked 1, marked 0, outside-root 0, empty
register 2.

audit-kinds has always reported what it found and was never asked whether it can
find anything, while its clean runs are cited as evidence that fifteen labels are
grounded. --selftest pushes three synthetic rows through the real classifier and
reads its verdict: citing nothing must read BARE, a real path ok, a missing path
DANGLING. Verified two-directionally -- an extractor stubbed to accept everything
returns exit 2. Asserting in check-all.

All four submenus are now measured to reset -- LOAD GAME, TUTORIAL and OPTIONS
joining EXTRAS -- and the main menu remains the only screen that remembers. Three
of the four are not in this export, so no authored value changes.

NOT promoted to a rule, deliberately. 'Submenus reset' at 4/4 is better evidence
than the 2/2 that made wrap a menu-wide rule, and adopting it would change nothing
today because the only submenu this port ships is already measured. What it would
do is pre-decide the next screen from a generalisation instead of a measurement --
the trap that nearly let a derived rule overwrite EXTRAS' measured opening item.
The guard prints the 4/4 finding beside its per-screen values so the evidence is
visible without being load-bearing.

MISSION-SELECT-versus-top-item stays open: none of the three separates it, each
opens on its own first item, and NEW GAME is untested.

Remaining without a harness self-test: verify-transcode-fidelity. Every asserting
check passes, 13 of them.

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.
