Two things, and the first is a refutation of mine that lands.
1. THE 12-UNIT BRACKET IS WITHDRAWN. It excludes nothing.
I kept 60 units/s on the ground that "12 declared units measured at 0.14-0.30 s
gives 40-86 units/s, so 120 is excluded". The Decoder refuted it and I checked
the arithmetic myself:
120 units/s predicts 12 units in 0.100 s -- BELOW the sampler's own 0.125 s
resolution, which the source doc states in its own words ("at a sampling
resolution that cannot do better"). A 0.125 s sampler reports such an interval
as about one sample, ~0.125-0.14 s. So the 0.14 s low end is the INSTRUMENT'S
FLOOR, and 12/0.14 = 85.7 is an upper bound produced by dividing by a floored
duration. It is the value 120 predicts once the sampler is accounted for.
🔴 And the deeper error is mine rather than the arithmetic. I argued the leg
survived because it "never touched a frame count". True, and INSUFFICIENT: every
wall-clock duration off Canary is true/speed_factor, so apparent units/s = true x
speed, and the speed factor is precisely what makes the three routes disagree. I
checked the leg for the WRONG CONTAMINANT. Frame-free is not clock-free, and on
this emulator clock-free is the property that matters.
What survives is the half I did not lead with: the declared 12 units are
independently confirmed as SIX FRAMES by screen-transitions.md's 255/6-per-frame
ramp, with no wall clock in it. That is evidence about units per FRAME -- never in
dispute -- and silent about units per second.
So 60 has NO surviving bracket. It stays because nothing supports 120 either and
moving a shipped timeline on no evidence is worse. That is a default, not a
derivation, and the entry now says so. `kind` is already `authored`.
2. 41 % OF THE REPO PATHS CITED IN MY OWN docs/port/ PROSE DID NOT RESOLVE.
The Decoder observed that everything they hand me links into docs/re/ files that
live only on their branch, so every link they send dangles from here. I turned it
on myself and it was worse than I expected: 37 of 91, in two classes.
19 on their topic branch -- real files, not merged. Not errors, and no one in
this container can fix them; the fix is a merge.
7 resolve NOWHERE: docs/BLOCKED.md, docs/DECISIONS.md, docs/FORMAT.md,
port/manifest.json, port/screens/title/*.json. Left behind by the monorepo
move and the export/ rename. Simply wrong -- a reader following one gets
nothing, and nothing had ever told anyone.
All 7 fixed. audit-kinds checks citations in authored/; nothing checked the
PROSE, which is where this port explains itself.
New: tools/port/check-citations, wired into check-all with its control. It fails
ONLY on the resolve-nowhere class and reports the peer-branch class, because a
check that went red for a state nobody here can change is the shape the display
guard exists to prevent. The --selftest plants a dangling citation and requires it
caught, AND a real one and requires it passed -- both directions, since a scanner
that flagged everything would also "pass" the first.
Not settled: finding 3 has no surviving cause and 60 now has no surviving
derivation either; the ~1.0-1.2 menu residual; pgloading_loop5's residual; 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.
