Two things, and both are about a label being wrong rather than a value. 1. THE rest() PAIR IS MOOT FOR THIS PORT, and that is measured rather than waited on. R1 re-opened both legs, 8 further claims died with the ⟨render-vs-capture⟩ instrument, and ScreenView.settle_time() uses rest.t -- so this port has been sitting on a question with no instrument behind either side. An element reaches the plateau-less fallback exactly when no two consecutive keyframes are identical. Census over all sixteen screens at every nesting depth: FIVE elements, three distinct -- palogo_sqex_eff, palogo_anima_eff, ptlogo_eff3, plus two region twins. And every one of them is transparent where its rest pose is read: publisher_logo t=140 not drawn: palogo_sqex_eff (transparent) developer_logos t=117 not drawn: palogo_anima_eff (transparent) title_jp --pose=rest not drawn: ptlogo_eff3 (transparent) So no rest() rule -- plateau-plus-dwell, `last`, `maxalpha` or `lastall` -- can change any pixel this port draws. That is why the splash rows score 0.01 % against their captures while resting on a heuristic nobody can currently defend: it is not load-bearing there. 🔴 And the brief's "the two splashes are the ONLY screens reaching that fallback" is narrowly refuted -- title_jp reaches it too, via ptlogo_eff3. Stated as a measurement of the CURRENT export: the record-layout fix re-timed keyframes corpus-wide and a plateau is exactly what that could create or destroy, so this does not say the claim was wrong when written. ⚠️ It does NOT rehabilitate rest.t, still wrong for transients like ptlogo_back2eff1 whose rest.t=54 is a two-frame flash's PEAK. That is a plateau case, not a fallback case, and nothing here touches it. 2. keyframe_units_per_second RECLASSIFIED measured -> authored. The value does not move; the label was false. The Decoder withdrew their guest-frame-rate finding the same day they published it, and this file carried `kind: measured` on its strength. Three routes now disagree -- withdrawn movie cadence 60, vblank ~120, title-plate-delay ~56 -- and at most one is right. 60 is kept, and not as a coin toss: the one leg of this file's own reasoning that never touched a frame count still brackets it. The transition quad is declared black for 12 units and the capture measured 0.14-0.30 s, i.e. 40-86 units/s. 60 sits inside; 120 does not; ~56 is 7 % away and inside the same bracket. 🔴 audit-kinds caught my first attempt at this, DANGLING: I cited guest-frame-rate-WITHDRAWN.md, which is on their branch and not in my checkout -- citing a document I cannot read. The check doing exactly its job. The withdrawal is now named in prose and labelled as coming from their message. 📌 Their method note is worth more than the number and is recorded in the file: their pre-registration named three ways the ruler could lie and guarded two; the third occurred, and a PERFECT 1.0000 is precisely what it produces. A clean result on an instrument whose key assumption is unguarded is not confirmation -- the cleanness may be the failure mode's own signature. Same family as this port's non-inverting latch check, which passed for the wrong reason until its control failed. Not settled: finding 3 still has no surviving cause; the ~1.0-1.2 menu residual against the additive-capable reference; pgloading_loop5's own residual; and the allowance still waits on its grep trigger.

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/

mods/ drop-in overrides. Yours

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

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 ·
❔ HYPOTHESIS · ❌ REFUTED. A withdrawn result is kept with its reasoning
rather than deleted — that is why the numbers here can be trusted.
