A snapshot of the non-game files as of0148cb8("port: F5/F6 hand-off -- one-minute human checks, and a refutation attempt that survived", 2026-09-04), the tip of auto/port-p6-audio. The branch was deleted from the server on 2026-09-17 during the consolidation cleanup; issue #7 asks for this work as a reviewable PR, so it is recovered here before the commits are garbage collected. Contents: the 84 files the branch changed relative to its fork pointb305aa4, which is this commit's parent. The tree is therefore 0148cb8's tree with the 854 exported game assets left out -- export-probe/, export-probe2/, three .wav renders of game audio and adv-v2-screenlog.tsv. Game data stays out of git; the exporter regenerates those from the disc. docs/port/DECISIONS.md still refers to them by name. Not recovered: the branch's own 366 commits. Keeping them would make those assets reachable again, so this is one snapshot instead. The original commits stay unreferenced in the server's object store, and in this clone under the local branch archive/port-p6-audio, until either is garbage collected. Refs #7. The OPTIONS work that issue #6 asks for is a subset of this branch, also recovered as recover/options-menu. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

//! Do any screens THIS PORT SHIPS carry a record that declares a cycle while all
|
|
//! its poses sit at t = 0?
|
|
//!
|
|
//! The substantive finding from the denominator thread: 1 530 nested records
|
|
//! disc-wide are timed with every pose at t = 0 and still declare a nonzero
|
|
//! `+0x08`. A static record that declares a cycle length is a real thing, not a
|
|
//! counting artefact — so the question for the port is whether it holds one of
|
|
//! those still while the disc says it cycles.
|
|
//!
|
|
//! Scoped to `GP_TITLE`, because that is the archive the port exports.
