- 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).

New L0 crate effectcraft-opusenc: clean-room RFC 6716 CELT-only encoder
(fullband 48 kHz, 20 ms packets, mono/stereo as dual L/R stereo, constant
packet size from the bitrate) with the RFC 7845 OpusHead and pre-skip.
Forward low-overlap MDCT, inter/intra coarse energy, fine/final energy,
the decoder's exact allocation, recursive band splitting, PVQ search and
codeword indexing, silence frames.
crates/export depends on it; filmcraft-opus (dev) is the round-trip oracle
in tests/opus_roundtrip.rs, with ffmpeg reading an in-test Ogg Opus file
as a second oracle when installed.

Extruded text keeps per-character 3D: each glyph's outline is extruded in its own space and
placed by its animated matrix; shape layers extrude their fill outlines (gradients use their
mid colour). Shadow-map bias scales with the texel footprint at the receiver and the PCF
reach (no acne on curved casters), identically on CPU and GPU. Docs: Advanced 3D in
architecture.md, parity table updated (3D, Text).

Liquify stores its strokes as effect data and replays them into a cached
displacement mesh; liquify.stroke / liquify.clear commands for agents.
Rolling Shutter Repair measures motion with effectcraft-track KLT (new
effects -> track same-layer edge).

Region-of-interest frames render on the CPU path; the viewer keeps main's
frame drawing (Show Channel, exposure, ROI) and reads GPU-composited frames
back. Keeping frames as native egui-wgpu textures stays implemented behind
RenderSource::gpu_display (off).

New L3 crate effectcraft-gpu: a wgpu compute backend for the per-frame
compositing walk (layer transforms with the CPU's nearest/bilinear/bicubic
sampling and minification pre-filter, motion-blur accumulation, track
mattes, Preserve Transparency, layer style passes and knockout, all 38
blend modes as a WGSL port of color::blend, 8/16 bpc clamp+quantise,
colour-space conversions). 3D runs, adjustment and wireframe layers run on
the CPU between GPU steps. GPU effects with the CPU semantics: Gaussian,
Fast Box and Directional Blur, Glow, Levels, Curves, Hue/Saturation, Tint,
Fill, Gradient Ramp, Fractal Noise, Drop Shadow, Brightness & Contrast,
Exposure, Invert, Transform (registry gpu badge from effects::GPU_EFFECTS).
render: Backend (Cpu/Gpu/Auto) in RenderOpts, the Accelerator trait and
Renderer::accel, GPU effect chains in the effect stack, hooks for the GPU
walk. Project setting gpu_acceleration (Mercury GPU Acceleration / Software
Only), render.backend command, file.projectSettings renderer. Session and
Render Queue exports carry the accelerator. CLI --gpu and bench --gpu.
Tests compare GPU vs CPU renders (blend modes x bit depths, transforms,
masks, mattes, motion blur, colour management, styles, collapse,
adjustment fallback, every GPU effect) and skip without an adapter.

text.edit/endEdit/setSelection/moveCaret/insert/delete, layer.setText range,
caret insertion style, Paste Text and Match Formatting / Paste Text
Formatting Only (stubs removed); Character/Paragraph/Properties panels act
on the selection.

Composition viewer interaction parity with After Effects:
- Snapping (View > Snapping, the Tools bar checkbox, Cmd/Ctrl inverts while
dragging): layer edges, centres and anchor points, mask and shape-path
vertices, comp edges/centre, guides (Snap to Guides) and grid (Snap to
Grid), with highlighted target box / line / cross feedback. Pure maths in
engine::viewer (nearest target within tolerance, priority ties).
- Rulers (Cmd+R) with live pointer markers and a draggable zero point;
guides dragged out of the rulers, moved in the viewer, dragged off to
remove (view.moveGuide / view.removeGuide), lock respected; proportional
grid.
- Show Channel (RGB/Red/Green/Blue/Alpha/RGB Straight, Colorize), exposure
(+/- stops in linear light, reset), Take Snapshot (Shift+F5) with a stored
render and Show Snapshot (F5 held / button held), Fast Previews (Off,
Adaptive Resolution, Draft, Fast Draft, Wireframe), Resolution > Custom.
- Region of interest: drawn in the viewer; RenderOpts.roi renders only that
rectangle (crop of the full render, tested), Crop Comp to ROI uses it.
- Bottom bar in AE 2026 order ("136.1 %", "(Full)").
- Shape Pen (SHP-1): Pen on a shape layer / nothing selected draws Shape n
groups (Path 1, Stroke 1, Fill 1) via shape.newPath; the G slot cycles
Add / Delete / Convert Vertex and Mask Feather; mask.* vertex commands
work on shape paths; mask.insertVertex / mask.convertVertex; marquee
vertex selection, Alt-drag/click converts, double-click free transform
box (path.freeTransform on masks and shape paths).
- Motion paths (ANM-3): keyframe dots and spatial tangent handles, dragging
keys (keys.set) and tangents (keys.setSpatialTangents), parented layers.

Collapsed precomps draw their layers straight into the parent with
concatenated transforms and multiplied opacity (nested blend modes and
adjustment layers act on the parent); a non-Normal mode, track matte or
Preserve Transparency composites the collapsed result as a whole; masks,
effects or styles force a flattened render. Nested 3D layers use the
parent's camera and lights and join the parent's 3D run when the precomp
layer is 3D. Continuously Rasterize re-rasterises text and shape layers at
their on-screen scale. Draft quality samples nearest-neighbour, Wireframe
draws the layer bounds. layer.slip / slipBack (Alt+PageUp) / slipForward
(Alt+PageDown) and dragging the timeline source bar slip the source under
fixed in/out points, clamped to the source duration; undoable.

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.

pressure dynamics, modes, channels), eraser modes, clone from layer/time,
cache keys include visible strokes. paint.stroke/options/brushPreset/
setCloneSource/removeStroke/presets. Layer panel with paint tools, Paint
and Brushes panels.
Puppet: Puppet effect with meshes and Position/Advanced/Bend/Starch/Overlap

Delaunay with constraint recovery; ARAP (Igarashi 2005) two-step solve with
CG; anti-aliased texture-mapped rendering with overlap depth. puppet.addPin/
movePin/setPin/removePin/mesh/info. Puppet tools in the viewer with mesh
overlay and header options.

layers or glyph shapes; transforms with parenting, separated position,
anchor; keyframes with speed/influence converted to normalised i/o tangents,
hold keys, spatial ti/to; all shape items incl. gradients, dashes, trim,
repeater and path operators; masks, track mattes, blend modes, time remap,
timing, markers, optional expressions, a few Lottie effects) with a warnings
list for what Lottie cannot express, and the inverse import. Commands

Tracker panel (Window > Tracker): Track Camera / Warp Stabilizer (disabled),
Track Motion / Stabilize Motion, Motion Source, Current Track, Track Type,
Position/Rotation/Scale, Motion Target with Edit Target..., Options...
(Motion Tracker Options dialog), Analyze (1 frame back, back, forward,
1 frame forward; stop while running) with progress, Reset and Apply (Apply
Dimensions dialog). Track point widgets in the viewer: feature and search
regions with corner handles, attach point crosshair and track path, all
draggable through track.setPoint (one undo step per drag). Automation ids for
every widget; headless UI test.
Tracker: featureless regions no longer drift (ties keep the prediction, only
confident matches predict motion). docs/agents.md: tracking example.

- apps/effectcraft-web (L6): eframe web runner booting the shared EffectcraftApp with a browser
session: in-memory file table, <input type=file> pickers and drag-and-drop for open/import,
downloads for Save and Render Queue outputs (several files as one stored .zip), and the
window.effectcraft promise API over the control channel. Demo project on start.
- wasm32 runtime fixes: web-time for Instant/SystemTime (render, engine, export, ui-egui);
Frames renders queued jobs on the UI thread (Frames::pump) instead of a thread pool;
Render Queue runs inline; relative outputs resolve under / ; control PNGs inline.
- effectcraft-export: per-job output Sink (files to memory instead of disk); host FileExporter
carries it; test that sink exports touch no file.
- xtask web [--dev] [--serve PORT] (wasm-bindgen 0.2.129, optional wasm-opt, COOP/COEP server);
effectcraft-web in WEB_CRATES. docs/web.md, headless Chrome smoke test, favicon (+attribution).
