Sylpheed port agent d7d1fa35db port: Q10 correction does not reach me; the register's cost is per-mention
Their stale Q10 row does not touch my tree: stems_why already reads 'a bank is
exactly TWO waves of identical duration', the corrected understanding, and the
three-sub-waves discrepancy is recorded here as refuted. stems: sum unchanged. Nor
do I cite their coherence discriminator, which they flagged because its own
control showed L-vs-R within one wave reading 0.22-0.50, so its premise fails in
this material.

Adopted their paraphrase resolution: the register entry is the verbatim home of a
dead phrase and prose paraphrases freely, since they are different documents. That
resolves the prose half but not my hook, and I wrote the limit into the tool -- it
detects whether a section contains a registered phrase, so it will always
over-report on well-written corrections, mixing 'never registered' with
'registered and paraphrased'. A prompt to check, never a defect count.

Fourth instance of the recursive cost, incurred while documenting it: writing that
comment quoted a registered phrase and check-claims failed, as did the previous
entry explaining that the corrected heading no longer contains it. Both marked.

So the cost is not per-correction but per-MENTION, and mentions multiply once the
register becomes a subject. Four instances, each inside text about the mechanism.

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-cli and 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

Xenia Canary is a separate repository: it is a fork tracking upstream, and it carries our instrumentation.
