Rows 1 and 2 were still labelled '(P3, blocking)' while P3-P7 have all shipped. Audited all five against HANDOFF and checked whether the port ACTED on each answer: splash by entry index (publisher_logo 10/13 exported), focus ring ptbtneff01 drawn, rotation about pos+pivot, gamma floor in verify-capture's header. Four struck, one (rotation) still a human decision. HANDOFF ask 2 tells the port to author a ~24-unit fade constant. That is stale: the corrected record layout leaves no untimed keyframe, and measuring what the file carries shows the black quad ramping 0->255 over TEN units. Authoring 24 on top of it would run the fade 2.4x too long. The mechanism ask 2 describes is confirmed in the file; its number is not. Offered as a hypothesis, not a finding: in-file ramp 10 + measured hold 10-14 = 20-24 units = 0.33-0.40 s, bracketing the measured 0.4 s at the top -- so the 0.4 s may be ramp + hold, needing no constant at all. Also surfaces a disagreement in my own tree: black_hold_units 9 (0.15 s) sits below HANDOFF's measured 0.17-0.23 s plateau. Not changed; recorded as an ask.

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
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.
