Ask #1 measured: held at the title with no input the plate oscillates ~23 cycles per window with no decay and NEVER goes off -- floor 159 thresholded pixels, pulse bottoming at 714. A glow alone cannot do that (0 -> 80 -> 0); a steady base plus a pulsing glow can, and 714/1520 are base-only and base-plus-glow. The port already had the base right: ptbtn00's fade to 0 at t=244 is its EXIT ramp, and while held the base sits at alpha 255. The glow was missing. The defect was in the renderer, not the entry I deleted on 2026-08-29. _draw treated a looping record like a focused one -- drawn INSTEAD of the base, which is right for a focused button and wrong here. I deleted the right thing for the wrong reason. A looping record now draws OVER the base and the entry is restored. Rendered: 95.68 base only, 115.52 at peak, period 1.980 s against a declared 120 units = 2.000 s, ratio 0.990. Visible on the boot path; not under --screen --overlay, where a static overlay poses at its arrival by design. Authored in UNITS on their instruction, with their three limits verbatim: one boot, does not distinguish boot from attract title, and 714/1520 is not an alpha ratio so no duty cycle is inferred.

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.

Confidence is per claim, never per document: ✅ CONFIRMED · 🟡 PROBABLE ·

rather than deleted — that is why the numbers here can be trusted.
