Bit-for-bit test: every frame of the Roto Brush chain equals a direct
segment_with / propagate_with call with no model.

Test with a tracker that always errors: roto.propagate completes, every frame
comes from the classic engine (status source: classical), IoU unchanged.

When the chosen model has a tracker, roto.propagate runs one tracking pass over
the span: prompts from the strokes (a handful of points, which SAM 2 trusts),
the clip tracked both ways, each frame's probability map refined by the same
graph cut with the strokes as hard constraints. Results are cached under their
own keys with a per-frame confidence and an occluded flag; roto.status reports
them (source: tracker|classical). Without a tracker nothing changes.
Real weights: IoU 0.98 on all 21 frames, confidence 0.99.

Sam2Mask wraps the image path behind the Roto Brush's MaskModel interface
(cached frame encoding, bilinear mask resize). The engine loads the verified
weights natively (not on wasm). Checked with the real file: install, notice,
load, use by Roto Brush 3.0, deselect.

Apache-2.0 entry pinned to a Hugging Face commit with its SHA-256 and size,
listed in Settings > Roto Brush and installable with the existing verified
install flow. No weights are bundled.

File ▸ Export ▸ Adobe Premiere Pro Project… pre-rendered every layer Premiere can't show to
ProRes 4444 with the window waiting: minutes on a large comp, which Windows reports as not
responding. The export now runs as a job (Window ▸ Progress, cancellable, with per-layer
progress) when started from its dialog (`background: true`); without it, the command still
waits and returns the same result.

A slip on a layer with no source handles succeeded with `delta: 0` and nothing else, which
read like a no-op bug. The result now carries `requested` (seconds) and, per layer, `clamped`
when the source could not move that far.

Create Split Layers Above Original Layer became on by default in #2083, but a settings
file saved before then still holds `false` (every later save keeps it), so Split Layer
kept stacking the new layer below. Settings version 4 moves a stored `false` to the new
default once, like version 3 did for the old disk cache size; a choice made since stays.

Add Per-Corner Roundness to Rectangle Path: a checkbox (off by default) and four Pixels properties (top-left, top-right, bottom-right, bottom-left). New rectangles initialise the four values from their Roundness, so ticking the box keeps the shape; the radii are animatable and expression-driven.\n\nrect_radii() builds the path clockwise from the top-left with kappa quarter-circle arcs. Overlapping radii scale down like CSS border-radius; negative and non-finite radii are square; rect() delegates to it, so uniform roundness clamps to half the shorter side as before.\n\nLottie rc has one r: four equal static radii export as that value; mixed or animated radii export roundness 0 with a warning. Import puts r into the four per-corner values so ticking the box on an imported rectangle keeps the shape.\n\nTests: path geometry and clamping, rendered per-corner pixels, Lottie equal/mixed/checkbox-off export.
The renderer applies every ancestor's transform, so a scaled null above a
camera already carries the camera's children. A Scale key with one shared
ease gets a separate Z ease before its speed is scaled.
Position speeds stretch with the path's direction at each key and Scale's Z
speed with the factor, so the ease keeps its shape. A 3D layer under a 2D
parent scales its own Z only when no 3D ancestor's Scale already carries it.
A 2D parent's Scale carries no depth, so its 3D children scale their own Z.
Percentage guides keep their percent exactly instead of drifting by rounding.
Tests now check the specific errors and cover a layer parented to a camera.
Like After Effects' File > Scripts > Scale Composition.jsx: a factor, or a new
width or height that keeps the aspect ratio, in one undo step. Layers whose
parent has a Scale follow that parent; nested precomps and expressions are
left as they are. No dialog yet.
