Take 2 is a good file: it passes check-capture (I re-ran it rather than cite the Decoder's run), carries a screen log, and was recorded with the sink's channel_map set equal to Canary's own. BEFORE REPORTING A SECOND NEGATIVE I ASKED WHETHER MY METHOD COULD DO THE JOB, by building a synthetic mix -- the bed plus the three voice streams -- and hunting the bed inside it. It failed: r=0.415, against the r>0.8 bar my earlier negatives were judged against. So the instrument that produced "the capture contains no ADV audio" could not have found ADV audio in a mix even when it was certainly there. That conclusion was right -- the Decoder's tone control proved take 1 corrupt independently -- but it was right BY LUCK and I reported it as measurement. The three controls I was pleased with tested that the method finds a clean signal in a clean reference, which was never the task. REBUILT AND CALIBRATED IN BOTH DIRECTIONS. Band-limit so the target dominates, then judge on LAG and MARGIN rather than absolute r -- r>0.8 is correct clean-against-clean and meaningless for a component in a mix. bed, 40-180 Hz in a mix containing it r=0.663 lag 0.0 s margin +0.111 bed, 40-180 Hz against a voice-only mix r=0.262 lag wrong margin +0.005 voice, 300-3000 in a mix containing it r=0.810 lag 0.0 s margin +0.248 voice, 300-3000 against the bed alone r=0.358 lag wrong margin +0.005 A 20-50x separation in the discriminating statistic. Written up as AUDIO-VERIFICATION.md section 6, retraction included. THE NEGATIVE NOW STANDS ON SOMETHING. All six of take 2's channels, against both targets, sit in the known-absent regime: margins 0.000-0.017, lags scattered from -72 to +255 s. Take 2 contains neither the movie's WMA bed nor the cutscene voice. Two captures, differently configured, the second provably free of the channel-map fault, with a screen log saying the movie was on screen, and neither carries either source. Handed back: a capture path still losing the mix, or the guest not emitting these sources during the movie, and only one side of the wall can tell those apart. If it is the second it reaches the port directly -- the export's movie audio comes from the .wmv's WMA track. Also noted: the message gives 253.3 s, the file is 318.539 s. The screen log agrees with the file, so it is a mis-stated number, but a length quoted in a provenance claim should match the artefact.

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.
