What

Step 8 — first keystone of the entangled-core split. Lifts the 7 reassigned shim scalars out of main.js's IIFE scope into an SH container in state.js:

shimsInstalled, shimsUsable, coreCurrentTimeDesc, corePausedDesc, coreDurationDesc, coreNativePlay, coreNativePause

Same rationale as the S container (step 4b): ES imports are read-only bindings, so reassigned scalars can't be export let — they need SH.x = …. These are read across the transport layer and onSongReady (SH.shimsUsable gates the sloppak takeover), so they must be shared, not private to the future shims module.

Pure state-lift, no behavior change. No function moved yet — this unblocks extracting the transport+shims layer as a module (a later PR) without recreating the read-only-binding problem.

Tests

Full suite green (npm test, 41 pass); tests/test_manifest.py green. Codex preflight: 0 issues. Rewrite audit: 0 double-prefixes, 0 bare refs left, no key/shorthand/string-literal collisions.

On-device smoke pending — this touches the transport-takeover path (SH.shimsUsable gate), so verify playback + transport still work.

Summary by CodeRabbit

• Bug Fixes
  • Improved the stability of audio playback controls, reducing issues that could affect play/pause behavior and song readiness handling.
  • Made transport setup more reliable so playback shims are applied consistently without interfering with normal playback flow.

Pull request overview

This PR is a refactor-only “state lift” that moves the #audio transport-shim mutable scalars out of src/main.js’s IIFE scope into a shared SH container exported from src/state.js, matching the existing S container pattern and enabling future module extraction without running into read-only ES import bindings.

Changes:

• Added export const SH = { … } in src/state.js to hold shim install/usable guards plus captured core descriptors and native play/pause functions.
• Updated src/main.js to import SH and replace all former local shim scalars with SH.* accesses/mutations.
• Updated the onSongReady takeover gate to use SH.shimsUsable.

📝 Walkthrough

Walkthrough

Audio transport shim state (install/usable flags, captured property descriptors, and native play/pause bindings) is moved from module-scoped local variables in src/main.js into a new shared SH object exported from src/state.js, with shim installation, delegation, and song-ready logic updated to read/write SH instead of locals.

Changes

Transport shim state refactor

Layer / File(s)	Summary
SH state container definition src/state.js	Exports a new SH object with shimsInstalled, shimsUsable, coreCurrentTimeDesc, corePausedDesc, coreDurationDesc, coreNativePlay, and coreNativePause fields.
Shim installation and import wiring src/main.js	Imports SH; installAudioShims() guards re-entry via SH.shimsInstalled, captures descriptors/native bindings onto SH, and sets SH.shimsUsable after install.
Shim delegation to SH-stored state src/main.js	Native delegate helpers and #audio currentTime/paused/duration/play/pause shims delegate to SH-stored descriptors/functions when sloppak mode is inactive.
Song-ready gating on SH.shimsUsable src/main.js	onSongReady() checks SH.shimsUsable instead of the removed local variable before taking over playback control.
