`slb_leading_segment_disc` was SIGKILLed by the OOM killer in `docker/ci/run` at its 7 GB cap, so the documented 45/377 baseline did not reproduce on a 15 GB box. `PakArchive` holds the whole concatenated payload in memory and `sound.pak` is 1.01 GB (sound.p00-.p04). `bank()` and `bank_named()` opened it on every call -- inside loops -- and five tests opened their own besides, ~26 opens in all. With cargo's default thread count that is ~6.1 GB of archive in flight against a 7 GB cap with `--memory-swap` equal to `--memory`, so there is no swap to absorb it. The archive is immutable once open and every accessor takes `&self`, so one `OnceLock` instance is equivalent to N private ones at 1/N the memory. ⚠️ The failure mode is worth knowing: a SIGKILLed suite prints no `test result:` line at all, so it disappears from a scraped tally instead of failing visibly. The run still reported "0 failed" -- true, and useless. Check cargo's exit code (101), not the tally. Measured in the capped container, 7 GB, default threads: * before: SIGKILL (signal 9), 0 of 10 tests reported * after : 10 passed in 3.17s * (single-threaded before the fix: 10 passed in 22.64s -- the fix is also ~7x faster, because it no longer re-reads 1 GB from disc 26 times) * cargo fmt --check clean; cargo clippy --tests -D warnings clean Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
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.
