Refuted by the Decoder (f6-unit11): the two strips are batched into a single additive eight-vertex draw -- two quads -- and their log reader took the first vertex match per draw line and discarded the rest. Every analysis saw quad A and never quad B. No new capture was needed; pteff03a was in the same logs that were read as declaring it absent. Three of my claims fall with it, including one I put in a report to the human: 'the port draws two, the game's capture has one'. The port draws two and so does the game. My census stands; it now AGREES with the capture instead of contradicting it. ✅ Nothing in the port changed. I proposed gating pteff03a and held, because absence in one capture read by one probe is a lead not a finding, and because the check I asked for was a human's look rather than another measurement. That hold is the only reason this cost nothing. ⚠️ The absence claim cited the port drawing pteff03a as evidence the PORT was wrong -- a defect inferred in my renderer from a gap in a reader. Recorded generally: an absence is a claim about an instrument, not the world. A count of zero says only that nothing got through the reader. Every positive result on the same capture is untouched because those compare like with like on one quad; only the absence compared a count against zero.
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.

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.
