ScreenView now draws two builds at once, which it never had to before. It is a second ScreenView in the same SubViewport rather than a subordinate screen inside one: each build has its own timeline, its own textures and its own hold, which is the entire content of the finding, and Node2D siblings already paint in tree order. `paint_order` still means what it meant -- an ordering WITHIN a build. The delay is authored in flow.json on the BOOT STEP, not on the `title` screen. What was measured is the boot title; whether the plate is there when the title is reached again -- (B) from the menu, or after the attract movie -- is not, and hanging it on the screen would quietly claim that it is. REFUTATION, and it is the substance of this commit: the RE agent's authoring instruction does not reproduce the RE agent's own measurement, and the gap is 3.97 s. The instruction is "when build 4 has settled, wait 2.13 s, composite build 2". But build 2 has a group and this port plays groups -- ptbtn00 is alpha 0x00 at t=214, still 0x00 at t=236 while it slides 10 px up, and 0xff only at t=238, which is 3.967 s at 60 units/s. So the plate is first VISIBLE at settle+6.10 s, while what was measured -- the glyph counter leaving 154 -- is visibility at settle+2.13 s. Both groups starting together puts it 0.38 s BEFORE settle; build 2 starting at settle puts it at settle+3.97 s; landing on the measurement needs build 2's group to start 2.51 s after build 4's, which is not a landmark of anything. The measurement is untouched -- it is an observation of the running game and I have no standing to doubt it. What is refuted is the step that turns it into an authoring rule. So the port ships the instruction, prints the discrepancy on every boot, and files the row. Same call as the BGM sub-waves: a port that quietly picks the number that looks right destroys the evidence, because a corrected boot looks exactly like a correct one. Also refuted, and it was mine: BLOCKED.md has said since P2 that "no element's alpha reverses direction anywhere in this export, so nothing pulses". ptbtn00 reverses -- 0x00 -> 0xff -> 0x00 -- and it was in the export the whole time. The claim had been checked against the screens P2 happened to be animating. The port still draws no pulse, because no reading of this group yields the measured 2.24 s: the whole group is 4.47 s and from its first keyframe 0.90 s. Gate: `--boot --capture=` writes one frame of the composited end state, instead of the 600-PNG filmstrip that was previously the only boot artifact. `--screen=title --overlay=press_start` raises the same composite in two seconds for anyone who does not want to sit through 137 s of Theora.

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.
