Phase 2 as a file. Six settings where two are load-bearing and both were missing from the first draft is the shape of thing that gets mis-clicked at 1am, so it goes through the API: what was applied is readable in a diff, and `--verify` can re-check it later instead of it being checked once. --verify states its expectations INDEPENDENTLY of what the apply path sends. A check derived from "whatever we posted" cannot fail -- it re-derives the expectation from the thing under test, which is the same instrument-shaped failure as a check that passes on an instance with no rule at all. It also asserts both agents are still Write and not Admin, because an agent promoted to Admin can edit the rule and then merge, so a green rule proves nothing on its own. That is the `gitea-verify` card from "Still to build"; what is left of it is only putting it on a timer. `block_admin_merge_override` stays false on purpose, and the reasoning is in the file: approvals are whitelisted to `fabi`, and Gitea will not let `fabi` approve a `fabi` PR -- so with the override blocked, a human-authored PR could never reach one approval and could never merge at all. The override is not a hole in the agent gate because the agents are Write, not Admin. Phase 1.2 pays for that; this is where it is spent. Reads the repository-scoped credential that already exists on the agent box (~/.sylph-git-credentials) rather than the issue-only ~/.sylph-gitea-api-token, which every branch-protection endpoint refuses. That keeps the setup needing no new credential, and keeps push rights on one machine.

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.
