36 declarations + the 4 autoplay/auto-exit gate statements. 359 lines. app.js 3,772 -> 3,242. Bodies VERBATIM. ━━━ THIS WAS "THE UNCUTTABLE HEART", AND IT IS 359 LINES ━━━ At the start of this epic, seeding a dependency closure from count-in, from loops, from section-practice, or from the JUCE seek shim all returned the SAME 178-function, 3,360-line set. playSong and showScreen called each other; everything called them; nothing could be cut anywhere. The conclusion — correct at the time — was that NO closure-based carve could touch it at any seed, and the answer was a host seam. That was true THEN. Every slice taken out since (transport, loops, count-in, section-practice, the library, the edit modal, settings) removed edges, and the strongly-connected component DISSOLVED. This closure is 36 declarations with an interface width of FOUR. The lesson is not that the seam was wrong — the seam is what MADE this possible, by letting the carves proceed against a cyclic core instead of stalling on it. The lesson is to RE-MEASURE. An SCC is a fact about a graph at a moment, not a property of the code. ━━━ THE BUG NO SCAN COULD SEE, AND THE A/B DID ━━━ First cut passed every gate — no-undef clean, no-cycle clean, 1045/1045, pytest green — and THREW IN THE BROWSER: "Assignment to constant variable." window.feedBack.holdAutoplay / holdAutoExit and their two event handlers are TOP-LEVEL STATEMENTS, not declarations. They WRITE this cluster's state (_autoplayHeld, _autoExitTimer, …), and an imported binding is READ-ONLY — so left behind in app.js, every one threw the instant the module existed. A dependency scan that walks DECLARATIONS cannot see them. Mine didn't. This is the same blind spot that nearly shipped a dead library A-Z rail (#896): app.js keeps its public API in top-level statements, and a call-graph is blind to every one of them. The extractor now finds them by construction — any top-level statement that WRITES a moved binding comes with the carve — and the gate statements live beside the machinery they drive, which is where they belonged anyway. ━━━ ZERO OUTSIDE WRITES, BY MOVING THE BOUNDARY RATHER THAN BUILDING MACHINERY ━━━ The autoplay scalars and the wake-lock state were written from outside the cluster, which would have forced a setter or a state container. But the writers — _releaseAutoplay, _acquireWakeLock — plainly belong here. Pulling them in left ZERO outside writes, so every export is a plain import. Same move as settings (#920): measure the writers before you reach for a container. VERIFIED. A/B against origin/main in two browsers, IDENTICAL, zero page errors — including the autoplay gate driven end to end: a plugin HOLDS autoplay, the song loads but does not start, the RELEASE fires it, and a stale release is a no-op. That is the exact machinery that was throwing. node 1045, pytest 2425, ESLint 0 (no-cycle clean), host contract 2/2, Codex 0. Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

// ── Centralized Keyboard Shortcut Registry ───────────────────────────────
|

//
|
||
// Plugins can register keyboard shortcuts via window.registerShortcut().
|
||
// Shortcuts are scope-aware (global, player, library, plugin-specific) and
|
||
// support optional condition callbacks for dynamic enable/disable.
|
||
//
|
||
// Panel-scoped shortcuts:
|
||
// - Each panel has its own shortcut registry
|
||
// - Use window.createShortcutPanel(id) to create a panel
|
||
// - Use window.setActiveShortcutPanel(id) to set the active panel
|
||
// - Shortcuts are registered to the active panel
|
||
// - This allows multiple panels (e.g., splitscreen) to have their own shortcuts
|
||
//
|
||
// API:
|
||
// window.registerShortcut({
|
||
// key: string, // Required: key value (e.key) or key code (e.code)
|
||
// description: string, // Required: shown in help panel
|
||
// scope: 'global' | 'player' | 'library' | 'settings' | 'plugin-{id}', // Default: 'global'
|
||
// condition: () => boolean, // Optional: dynamic enable/disable guard
|
||
// handler: (e) => void, // Required: callback when shortcut triggers
|
||
// modifiers: { // Optional: require modifier keys
|
||
// ctrl?: boolean,
|
||
// alt?: boolean,
|
||
// shift?: boolean,
|
||
// meta?: boolean
|
||
// }
|
||
// });
|
||
//
|
||
// Panel API:
|
||
// window.createShortcutPanel(id) - Create a new panel
|
||
// window.setActiveShortcutPanel(id) - Set the active panel for registration
|
||
// window.getActiveShortcutPanel() - Get the current active panel
|
||
// window.isInShortcutPanel() - Check if running in a panel (not default)
|
||
// window.getGlobalShortcutContext() - Get default panel for truly global shortcuts
|
||
//
|
||
// Note: The handler receives the KeyboardEvent, so you can check
|
||
// e.shiftKey, e.altKey, etc. directly in your handler if you need
|
||
// behavior that depends on modifier state (e.g., different actions
|
||
// for Shift+key vs key alone). Use the modifiers option when you
|
||
// want the shortcut to ONLY fire with specific modifiers.

// ES module, where that stops being true — module scope is not global scope, and
|
||
// each of these names would silently vanish from `window`.
|
||
//
|
||
// Everything below is reached by NAME from outside this file, so each one is
|
||
// made explicit BEFORE the flip. While app.js is still classic this whole block
|
||
// is a no-op (it just re-assigns what is already there), which is exactly what
|
||
// makes it safe to land on its own.
|
||
//
|
||
// The consumers are: inline on*= handlers in static/v3/index.html; on*= handlers
|
||
// this file builds inside template literals; static/v3/*.js; the capabilities;
|
||
// bundled plugins; and — easy to forget, since they live in other repos —
|
||
// feedback-desktop and the external plugins. Constitution II names
|
||
// `window.playSong` / `window.showScreen` / `window.feedBack` as the public
|

// real window: app.js's body finishes, the handlers go live on `window`, and a user
|
