- Collapsed precomps: the renderer records the precomp layers a nested comp is drawn through;
motion-blur sub-samples re-evaluate their transforms (when their motion blur is on) and map
times down through each one, so the precomp layer's own motion blurs its nested layers. The
containing (outermost) comp's shutter applies to collapsed layers. The GPU compositor gets
this through Renderer::placement.
- Shape and text layers whose content changes within the shutter (compared by its cache key)
draw their source at Samples Per Frame times and average them; the cache key covers every
sub-sample's content.
- Tests: tests_motion_blur_depth (collapsed vs flat, the containing shutter, shape content vs
the same move by Position); each fails without the change.
- Docs: roadmap, parity.

- effect.pickColor {effect, param|prop, x, y (layer px), average?}: the colour of the effect's
input at a point, set on the parameter (one undo step). Keying effects' Effect Controls
eyedroppers use it, since the shown frame is already keyed; Ctrl/Cmd+click averages 5x5.
- effects::aliases / name_matches: Effects & Presets and effect.list (MCP list_effects) find
Key Light by After Effects' name ("Keylight (1.2)").
- End-to-end test: a green-screen plate with an uneven screen, spill and soft edges keyed via
effect.apply "Keylight (1.2)", pick, Clip Black / White and a render; UI eyedropper test.
- Docs: parity, agents (green-screen recipe).

- A drag (keys.move steps sharing a merge key) applies its total offset to the keys as they
were before it (`Session::key_move`, `prop::shift_keys`): dragging over another key of the
property no longer deletes it; only the drop position replaces a key, as in After Effects.
- Keys of time-stretched layers move with the pointer: offsets are applied in comp time and
snapped to comp frames (drags and Alt+Arrow nudges; they moved by the layer-time distance).
- Shift+click toggles a key in or out of the selection (`keys.select {toggle}`); Ctrl+click
switches Linear ↔ Auto Bezier and Ctrl+Alt+click toggles Hold.
- Keys of locked layers can't be selected (clicks, marquee, Select All Keyframes), so nothing
edits them.
- Toggle Hold off returns an eased key to Bezier (it always restored Linear).
- Shift-dragging a key snaps to everything the current time snaps to — other keys, layer in /
out points, layer and comp markers, the work area — and a tooltip shows the key's time and how
many frames it moved.

Every 10 seconds the UI thread re-read the system's memory for the cache budgets, and on
Windows that starts PowerShell (`Get-CimInstance Win32_OperatingSystem`) and waits for it:
about a second, sometimes two, during which the whole app froze. The reading now runs on a
background thread (`sysinfo::MemoryWatch`); `Session::memory_tick` takes the last reading and
starts the next one, never waiting. Console programs started for it no longer open a console
window (`CREATE_NO_WINDOW`).

The web app reopens the last visit's project and, when it had unsaved changes, marked it
modified with `bump()`. Since M3.9 the modified mark follows the saved snapshot, and a bump on
the very project just opened counts as "back at the saved state", so restored changes looked
saved (no `*`, no unsaved-changes prompt). `Session::mark_unsaved` forgets the saved snapshot
instead: the project stays modified until saved, whatever is undone. Regression test included.

Removes the engine's production expect() calls: background-job polling (camera, mask, roto,
point and warp tracking, render queue) uses let-else / if-let instead of take().expect("job"),
command helpers bind what they checked instead of re-reading it with expect, the menu bar falls
back to an empty tree (logged) instead of expect()ing that a constant parses, and
autotrace/text animator group lookups no longer expect a just-inserted group. perf.rs, the
benchmark harness behind `effectcraft-cli bench --ops`, opts out with a module-level allow.
Test-only unreachable!() calls become panic!() (clippy.toml allows panics in tests). Denies the
panic lints in the crate.

Session::execute runs every command (UI, CLI, control channel, MCP, scripts; file import,
export and save are commands too) through guard::guarded, which catch_unwinds a panic that
escapes the command and returns EngineError::Other("command `x` failed with an internal error
(...); it was stopped and your project is still open"). Edits work on a copy of the project, so
a command that panics mid-edit leaves the project untouched. The desktop app also installs a
panic hook that logs every panic through the app logger (then runs the default hook).

- Quit and the window's close button, File ▸ New Project, Open Project, Open Recent, Close
Project, the demo project and a Home template show Save / Don't Save / Cancel when the
project has unsaved changes (Save asks for a path when untitled; cancelling that keeps the
project open). File ▸ Revert asks to discard. Before, all of them dropped unsaved work
without asking.
- The window title shows the project's path and `*` while it is modified.
- The modified mark follows undo: the session keeps the snapshot it last opened or saved
(`Session::saved_project`), so undoing, jumping in the History panel or rolling back a batch
to the saved state clears it.
- An edit that changes nothing (a value set to what it already is) records no undo step and
doesn't mark the project modified (`Project::same_content`, comparing untouched comps by
pointer).
- Agents' `engine.execute` / MCP calls are never asked; `ui.menu.invoke` shows the prompt like a
click (automation ids `dialog.unsaved.save` / `dontSave` / `revert` / `cancel`), and the
control channel's `app.quit {force: true}` skips it.
- Docs: architecture, agents, control protocol, parity.

- GPU in browser job workers: each job worker opens its own WebGPU device
(deferred readbacks); the Render Queue export and the analyses' frame loops
are futures (render::passes, offload::run_request_async) whose frames
render in passes, awaiting the device between them. GPU particles and
Advanced 3D read back under keys too. workers.jobs reports passes and
readbacks; the smoke test measures them.
- Layer buffers in the browser's OPFS disk cache: frame workers back their
layer caches with a PrefetchStore; the page plans what to fetch before a
request from recent misses (LayerPrefetch over the shared DiskIndex).
- Templates embed footage (default on, size-capped with a warning) and
creating from a template extracts it next to the new project / into
browser storage.
- ICC LUT profiles (lut8/lut16/lutAtoB/lutBtoA, from the public ICC spec) in
Simulate Output > My Custom RGB, baked into a 3D LUT for the viewer.

- GPU in the browser: each frame worker opens its own WebGPU device (Gpu::request_deferred) and
renders the GPU compositor and GPU effects with deferred readbacks (effectcraft-gpu deferred):
readbacks keyed by content start with map_async and miss, the pass returns placeholders, the
layer cache's gate drops inserts, and FrameServer::resume renders again once the device
delivered. Backend Auto times whole frames per comp in the workers. Frames with effects go to
GPU workers instead of the page. CPU fallback without WebGPU in workers (?nogpuworkers).
- Fix: a WGSL constant (3.40282347e38) that Chrome rejects invalidated every GPU kernel in Chrome
(the page's compositor too); a test checks every float literal fits f32.
- Disk cache in the Origin Private File System: workers write sealed frame entries with sync
access handles (temp file + move), the page keeps the DiskIndex (LRU under the settings' limit,
at most half the quota) and reads hits instead of rendering; survives reloads; blue cache bar.
- Storage manager: Settings ▸ Disk ▸ Browser Storage (usage/quota, persistent storage, Clear
buttons, automation ids) and storage.info / storage.persist / storage.clear (StorageHost).
- Docs: web.md (GPU workers, deferred passes, disk cache, storage manager, threading design:
one engine instance per worker), architecture, preferences, parity (WEB-1), roadmap.
- Tests: deferred passes vs CPU on a real device, placeholder gating, frame server passes and
Auto, GPU worker routing + disk cache across a reload, storage commands and widgets, store
usage by kind; smoke test: GPU effect frames in workers with pixel parity, disk hits after a
reload, storage manager.

Fill's ADBE Fill-0002 is Color (documented numbering); essential.* controls by name with
a listing error; an explicit comp param satisfies a command's active-comp enablement.

- footage.check: background footage check after File > Open (Progress panel), not an undo step
- timeline: track-matte / parent menus built only while open (was O(n^2) per frame);
expression-row lookup per layer; panels hold Arc<Comp> snapshots instead of deep clones
- Project panel: virtualised vertical scrolling, selection reveal, thumbnails rendered off
the UI thread
- effectcraft-cli bench --ops (engine::perf + ui-egui::bench)

Viewer frames render in long-lived Web Workers holding a project replica
(engine::remote: structural JSON diff/patch, Mirror, FrameServer); the
frame cache hands jobs to a RemoteFrames renderer (UI-thread fallback).
Roto Brush propagation runs in a job worker and streams segmentations
back (FrameSeg binary form), relayed to frame workers. Control-channel
wait:true commands whose job is offloaded reply when it ends. The Media
Browser browses a pluggable Browser: the file system on the desktop;
browser storage and File System Access folders on the web.

Preview panel: five shortcuts (Spacebar, Shift+Spacebar, Numpad 0, Shift+Numpad 0,
Alt+Numpad 0) each with saved options (include video/audio/overlays/layer controls, loop,
cache before playback, range incl. play around current time, play from, frame rate, skip,
resolution, full screen, play cached frames, move time to preview time), persisted in
prefs; playback.settings.get/set; the playback loop follows the preview plan.
Align panel: layer.align {edge, to} and layer.distribute {mode} engine commands (bounds
through transform and parents, one undo step); Align Layers to dropdown and Distribute row.
