- paint_logo draws docs/brand/artcraft-mark.png (the README's / getartcraft.com's ArtCraft

- The Timeline shows one tab per open comp (dock DocTab). Clicking a tab shows that comp; ×
or middle-click closes that comp's Timeline (comp.close), not the panel. Opening a comp brings
its viewer and Timeline tab to the front.
- Project panel: a double-click on an item's name opens it (a comp gets its own tab) instead of
renaming; Enter and the context menu rename.
- Tab drags: over a tab strip an insertion mark shows where the tab lands, and it lands there
(Layout::insert_tab), which also reorders a group's own tabs; side zones are unchanged.
- Tests: ui_tabs (double-click, tab switch / close, drag reorder and cross-group insert; an
ignored mid-drag snapshot); the Timeline close test follows the new behaviour.
- Docs: parity, control protocol.

- 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).

- J / K (Go to Previous / Next Keyframe) and Ctrl+Alt+A (Select All Keyframes) act on what the
Timeline shows, as in After Effects: the keys of its revealed properties, layer and comp
markers and the work area (they used every property of the selected or all layers, revealed
or not). The commands take `visible: [{layer, prop}]`, which the Timeline fills in; agents
calling them without it keep the previous behaviour.
- Graph Editor ▸ Auto-Select Graph Type (an "Auto" button, on by default as in After Effects):
the speed graph when every property shown is spatial (Position, Anchor Point…), else the
value graph; choosing Value or Speed turns it off.
- Docs: parity, agents.

- Go to Next / Previous Keyframe (K / J) also stops at the work area's start and end, as in
After Effects.
- With one keyframe selected, the Info panel shows its property, time and value instead of
"1 keyframes selected".

- Double-clicking a keyframe of a numeric property (or its context menu ▸ Edit Value…) opens
the property's value dialog for that key, as in After Effects (it only moved the current
time); other keys still move the current time to them.
- The keyframe context menu has Select Equal Keyframes, Select Previous Keyframes and Select
Following Keyframes (`keys.selectEqual` / `selectPrevious` / `selectFollowing`).
- Roving keys draw as small dots in the Timeline, like After Effects.

- `keys.transform {fromStart}`: each step of a merged drag gives the whole transform since the
drag started and applies to the keys as they were then. Keys squeezed onto one frame on the
way (Alt-drag scaling, the transform box) are no longer merged for good, and a slow
transform-box move, whose per-frame offsets rounded to nothing, now moves the keys.
- Dragging a key in the Graph Editor moves every selected key in time and value (it moved only
the grabbed one), by how far the pointer went from where the button went down (the key no
longer jumps under the pointer); Shift keeps the drag to the time or the value axis.
- Shift+click toggles a key in or out of the selection; Ctrl+click switches Linear ↔ Auto
Bezier and Ctrl+Alt+click toggles Hold, as in the Timeline.
- The transform box and the Timeline's Alt-drag scale send whole-gesture values.

- 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.

Each reading starts PowerShell on Windows (in the background since the previous commit); the
cache budgets only need to follow memory pressure, not track it closely.

The windowing layer delivers Ctrl+C, Ctrl+X and Ctrl+V as clipboard events instead of key
presses, and the shortcut dispatcher only read key presses: in the app, copying and pasting
keyframes, layers and effects with the keyboard did nothing (tests passed because they inject
key presses). Clipboard events now map back to their keys with the modifiers held (so Ctrl+Alt+C
and the other variants work too), except while text is edited in the viewer, which handles them
itself. Ctrl+V sends no event while the system clipboard is empty, so copying now also puts a
line naming what was copied on it ("EffectCraft: 3 keyframes").

Dragging a keyframe moved it a frame or two and then let go: the key's widget id includes its
time, so after the first move it was a new widget and egui ended the drag. The Timeline now
follows the whole gesture itself (`KeyDrag`: from where the button went down, by whole frames,
every selected key, one undo step), like After Effects. Holding Shift snaps the grabbed key to
the current time, the work area and composition markers.

Following AGENTS.md's Never crash rules for the M3 / M4 additions:
- Cache Frames When Idle panicked (`clamp` with min > max) when the work area was inverted
(start set past the end); an empty work area now has nothing to cache.
- `file.newCompFromSelection`: the sequence overlap times the layer count overflowed for a huge
`overlapDuration` (wrapping to a wrong comp length without overflow checks); negative or
non-finite values fall back to 1 s and the product saturates. The lead item is read with
`get()` instead of indexing.
- Layer Settings' enablement reads the first selected layer with `first()`.
- Regression tests for both (each failed before the fix).

ui-egui without expect()/unreachable!(): the frame pool is optional (rayon's global pool if the
OS refuses threads) and gets a panic_handler, because a panic in a rayon spawn() job aborts the
whole process by default; render-queue progress, the text-edit anchor and the GPU viewer
texture are bound where they're checked; the settings panel's Bool arm no longer panics.
Denies the panic lints in the crate.

Composition Settings ▸ Advanced has both options (they were missing from the model, the
renderer and the dialog):
- Preserve frame rate: nested in another comp, the comp shows only its own frames
(`EvalCtx::nested_time` floors the precomp layer's source time to the nested comp's frame
rate; used for the nested frame, its proxy, aux channels, collapsed transformations and the
viewer's internal wireframes), and the Render Queue renders it at its own rate whatever the
Frame Rate override (`RenderSettings::rate`).
- Preserve resolution: nested in a comp rendered at Half / Third / Quarter, it renders at full
size and the buffer's scale places it.
- `comp.settings {preserveFrameRate, preserveResolution}`, `comp.info` reports them, scripts
read and set `CompItem.preserveNestedFrameRate` / `preserveNestedResolution`, Pre-compose
copies them, and the dialog registers `dialog.comp.preserveFrameRate` /
`dialog.comp.preserveResolution`.

Composition ▸ Preview ▸ Cache Frames When Idle was only a saved checkbox. After a second
without input or edits it now renders the work area's frames (from the current time on, then
from the start) into the RAM preview, a few at a time behind the viewer's own frame, until the
work area is cached or the RAM preview budget is full.
Docs: preferences.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- Viewer Resolution Auto rendered at half its scale while a preview played, so frames cached
while scrubbing were not played and frames cached by the preview were re-rendered once it
stopped. Auto now follows the zoom alike playing and paused (Fast Previews still lowers it
while dragging).
- Cache Before Playback waited for every frame of the range: a range larger than the RAM
preview budget evicted its first frames and never started. The range is now cut to the
frames that fit (90 % of Settings ▸ Memory & CPU's budget) with a message, then cached and
played.
- The Info panel shows the frame rate a playing preview achieves and whether it is real time
(`Playback::achieved_fps` / `real_time`, automation id `info.previewFps`).
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- `FrameKey` carries a hash of the render options (`frames::opts_hash`): switching Fast
Previews (Draft / Fast Draft) or Realtime Shadows no longer shows frames rendered the other
way.
- Eviction drops the least recently shown frame (`Frames::get` touches it), not the oldest
inserted: a looping preview a little over budget no longer evicts the frame it shows next.
- Frames of earlier project revisions are dropped on every change (`Frames::drop_stale`); they
could never be shown again but held memory (and GPU textures) until evicted.
- The green cache bars (Timeline, Preview panel) count the frames of exactly what the viewer
shows — scale, 3D view / region of interest and options (`EffectcraftApp::shown_series`) —
instead of any frame at that scale.
- Playback loops compute the key's fixed part once (`EffectcraftApp::frame_series`).
- Docs: architecture.

- Pre-compose makes the new composition with the original's pixel aspect, background, motion
blur and frame blending settings and 3D renderer (`Comp::nested_like`); it kept only size,
rate and background.
- File ▸ New Comp from Selection records one undo step (two per item before) and takes each
item's pixel aspect. Several items selected open the New Composition from Selection dialog:
Single / Multiple Compositions, Use Dimensions From, Still Duration (default from Settings ▸
Import ▸ Still Footage), Add to Render Queue, Sequence Layers with Overlap, Duration and
Transition. `file.newCompFromSelection {single, dimensionsFrom, duration, addToRenderQueue,
sequence, overlap, overlapDuration, transition}`; `layer.addItem {duration}` for stills.
- Docs: parity.

- Locked layers can't be selected (Timeline click, Select All, Ctrl+Up/Down; shy layers while
hidden too) and are left alone by Clear/Delete, Arrange, Layer ▸ Transform and Center Anchor
Point, which fail when every target is locked (`commands::unlocked`, `commands::selectable`).
- Deleting a parent unparents its children where they are, in the same undo step: the
pick-whip compensation moved out of `layer.setParent` into `layer::parent_fixes` /
`ParentFix::apply`, which now also handles separated X/Y Position.
- Bring Forward / Send Backward move each selected layer one step (a non-contiguous selection
was squeezed into one block).
- Center In View / Fit to Comp keep a 3D layer's Z (and Fit keeps Scale/Anchor Z); Reset /
Center / Fit / Center Anchor Point work with separated dimensions (`layer::update_position`).
- Duplicate and paste keep parents and track mattes, following the copies when both were
copied; paste dropped them always.
- Docs: agents, parity.

- Layer ▸ Layer Settings on a solid or adjustment layer opens Solid Settings on the layer's
solid (it ran an empty command before): name (renames the layer and the solid), size, Pixel
Aspect Ratio, colour, and "Affect all layers that use this solid". It starts off, as in After
Effects, so changing a solid other layers share gives this layer its own copy.
`layer.settings {pixelAspect?, affectAll?}` → `{layer, solid?}`; `layer.newSolid {pixelAspect?}`.
- Nulls ask for their name; text and shape layers have no settings (the entry is disabled).
- Composition Settings / New Composition and Solid Settings register an automation id for
every control (`dialog.comp.*`, `dialog.solid.*`). Composition Settings takes any typed frame
rate besides the list, and New Composition starts from the last settings used.
- Colour buttons in both dialogs show the stored sRGB colour (`widgets::srgb_color_button`);
egui's linear picker showed it lighter.
- Docs: agents, parity.

- 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.

Off macOS `Cmd` maps to Ctrl, so Enter Full Screen's Ctrl+Cmd+F parsed
to the same keys as Find's Cmd+F and both commands were bound to Ctrl+F
(ui_and_menu_shortcuts_do_not_collide fails on Linux and Windows).
Shortcuts that use both Ctrl and Cmd can't be typed distinctly there,
so they are skipped when the key bindings are built off macOS.

- 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.
