§§1-9 were written on fabi-Hyrican-PC. On the other desktop the ~/.sylph-*
credentials do not exist, the Pi does not resolve, and stable is 1.90.0 rather
than the 1.98.1 §8 records -- so §8.2 (fetch the WASM bundle) and §8.4 (Phase 7)
cannot be run from here at all. Says which of the four steps can.
Measured rather than carried over: protection holds (10/10), fmt is 774 hunks
across 154 files, check-citations is 19, and the tests are 207/0/14 across 30
suites. Two of those need reading carefully:
* clippy DIVERGES. The runner is rustc 1.98.1 -- read out of job 794's log,
not assumed -- and is clean; here 1.90.0 exits 101 on only_used_in_recursion
at vfs.rs:85. That is #15 ceasing to be theoretical. It is NOT evidence that
CI's green is fake, which is the §7 lesson-5 inference in the other
direction.
* the test tally matches to the unit while measuring something else. 15
*_disc.rs files resolve disc_root() through a hardcoded absolute path, so
unsetting SYLPHEED_DISC does not skip them: the disc suites RAN here (1936 s,
mesh_consistency_disc alone 1220 s) and skipped on CI (2.4 s total) -- and
both report 207/0/14, because the skip path returns from a test that still
passes. Good news for #14, since this run is the stronger evidence; and worth
an issue, since SYLPHEED_DISC looks like a control and is not one.
I got that last one wrong first -- inferred "the counts cannot match" from "the
fallback resolves", which is §7's shape a sixth time, recorded as such.
Also: a plain `git clone` of this repo fails three ways on the pack that still
carries the 545 MB; --filter=blob:none works. And §6's tokio claim was
challenged and survived -- every use is inside a #[cfg(test)] module.

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
-- and RUNNING.md, which is how you actually start it
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.
