The tag was cut within the iteration, so screen.rs now calls ui_layout::loop_length_units and its local RATC guard and byte read are deleted. One line, as predicted -- and the doc comment promising that deletion is the only reason a temporary reading did not quietly become permanent. A pin bump moves the whole crate, not one function, and this pin is recorded load-bearing, so both commits between the tags were read before taking it:b5df02aadds the public function,d020845is comment-only -- two 'fixed code under an unfixed description' corrections. No behavioural change in either, and the oracle RMSEs confirm it: main_menu 13.21, extras 13.38, title 14.16, all identical across the bump.d020845is worth noting for what it is. The rest override's comment still claimed it tested the shifted time reading that the record-layout fix had refuted, and a continue branch was documented with the pre-fix rule. Both are the same failure this port hit in spin_period_units: a doc comment describing the rule the body no longer implements. Three instances now, across two agents and two languages. examples/record_loop_control.rs deliberately did NOT follow the API. The moment a control calls the thing it exists to check it stops being a control and becomes the API tested against itself; the falsifier means something only because the reading is independent. Re-run at the new pin, unchanged. So the port holds one copy of this reading instead of two, and it is the copy whose job is to disagree.

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/
base/ generated by the exporter. Gitignored, never hand-edited
mods/ drop-in overrides. Yours
docs/
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
agents/ how the agent team works together
tools/ capture harnesses, probes, the share tool
exchange/ transient inter-agent files. NOT in git
docker/ the agent containers
Where to start
docs/re/INDEX.md— what is decodeddocs/re/REFUTED.md— what has been tested and dieddocs/re/METHOD.md— traps this project has already paid fordocs/game/navigation.md— how the game is navigateddocs/port/MODDING.md— why the asset tree looks the way it does
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.
