- Persistence: settings, shortcuts, recent projects, imported media, saved projects and
auto-saves live in OPFS (IndexedDB fallback) through an in-memory mirror flushed in the
background (apps/effectcraft-web/src/store.rs, persist.rs); ConfigStore gains FileOps so
auto-save / recovery work in the browser store; the session snapshot restores the last
project + editor state on reload; File > Open Recent works from storage.
- Audio: Web Audio output (AudioWorklet, ScriptProcessor fallback) fed by AudioPlayback::pump
on wasm32; A/V sync from AudioContext.currentTime; meters; unlock on first gesture.
- Background jobs: engine::offload (WorkerRequest/WorkerReply protocol, Offload trait,
run_request); Render Queue, tracker, mask tracker, Warp Stabilizer and Roto Freeze run in Web
Workers (a second engine instance on the shared compiled module), progress streamed back;
cancel terminates the worker.
- GPU: WebGPU viewer frames drawn straight from the compositor's texture (gpu_display on
wasm32 when the viewer draws plainly); async readback (Gpu::read_display_async) for pixels.
- PWA: manifest, service worker precaching the build (xtask fills list/version), icons copied
from assets/app-icon; COOP/COEP kept from cached responses; offline reload works.
- window.effectcraft: saveToBrowser, listStored, removeStored, flush; info() reports storage,
audio, gpu, workers.
- Tests: native store + protocol + offload (render, track, cancel) tests; smoke.mjs extended
(GPU path, worker render responsiveness, audio gesture + playback, reload persistence,
Open Recent, offline reload).

PRJ-7. `engine::autosave` with the session hooks the frontends call:
- Auto-save: every N minutes a dirty project is written to "EffectCraft Auto-Save" next to
it (or a custom folder; untitled projects use the custom folder or the config dir) as
"<name> auto-save N.ecproj", rotating through max versions (oldest overwritten, extra
slots dropped when the maximum shrinks). Optional save when the render queue starts.
- Atomic writes for projects, auto-saves and config files: temp file + fsync + rename; a
failed write removes the temp file and leaves the previous file intact.
- Crash recovery: a session.lock sentinel in the config dir records the open project and
its latest auto-save; a clean exit removes it. At launch a leftover sentinel offers the
latest auto-save in a Recover Project dialog (Settings > Startup can turn it off).
- File > Open Recent (stored in the settings) with Clear Recent Projects; Increment and
Save uses After Effects naming ("Intro 2.ecproj"); Revert reloads the saved file.
- Commands: file.autoSave, file.recoveryInfo, file.openRecent {index|path},
file.clearRecent.
- Tests: rotation, interval/dirty tick, simulated crash mid-write, unclean-exit detection
and recovery, Open Recent / Increment and Save / Revert.

Keyboard shortcut presets in the engine (`engine::shortcuts`): every menu entry (including
ones with bound parameters), registry command and frontend command is bindable, scoped
application-wide or to a panel. "EffectCraft Default" is After Effects' layout and
read-only; editing it creates a custom preset that stores only its differences. Presets
are saved in the config store; the shortcut dispatcher and the menus read the active one.
- Commands: shortcuts.list, shortcuts.set {command, params?, keys}, shortcuts.reset,
shortcuts.preset {select|new|duplicate|delete|rename}, shortcuts.export/import (JSON),
shortcuts.conflicts.
- Edit > Keyboard Shortcuts: preset bar, modifier toggles (or held keys), an on-screen
keyboard coloured by scope (application-wide / panel-specific / both), key details,
a searchable list of every command, record-or-type assignment with conflict warnings,
reset to default; all widgets have automation ids.
- Tests: normalization, defaults conflict-free, conflict detection, custom preset creation
and persistence, preset lifecycle + export/import, dispatch uses the custom preset.

A real Settings model in the engine (`engine::prefs`): serde, versioned, dotted keys
(`general.undoLevels`, `labels.3.name`), migration of older layouts, unknown keys kept,
persisted through a `ConfigStore` trait (platform config dir on the desktop; MemoryConfig
for tests; the web app can back it with localStorage).
- After Effects 2026 pages (General … Scripting & Expressions) as a schema shared by the
dialog, `prefs.pages` and docs/preferences.md (rows not wired yet are listed there and
kept in step by a test).
- Commands: prefs.get, prefs.set {key, value | values}, prefs.reset {page?}, prefs.open
{page?}, prefs.pages.
- Wired settings: undo levels, path point size, tool tips, layers at comp start / CTI,
default spatial interpolation linear, Home screen on launch, new project template,
rendering progress in Info, adaptive resolution limit, cache when idle, fast previews,
theme + UI brightness, label names/colours everywhere (Label menu, timeline, project,
render queue, viewer), label colour for handles, grid colour/spacing/subdivisions, guide
colour, safe margins, still footage duration, sequence fps, audio output device and
output mapping, layer / footage / preview cache budgets, default 3D renderer.
- Settings dialog: AE's left page list + right content, OK / Cancel (restores) / Previous /
Next, every widget with an automation id.
