ObjectTracker interface in the segment crate (prompts on some frames, the
clip tracked both ways, each frame streamed with confidence and an occluded
flag), implemented by SAM 2. MaskModel::tracker() is None for other models.

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.

Click on frame 2 of a 7-frame clip with an occlusion, tracked forwards and
backwards: IoU 1.0000 on all 9 frame results, worst mask-logit error 0.0038,
object scores equal to 3 decimals.

Per-object memory banks, prompts on any frame, forward and backward
propagation with streaming results, cancellation, object pointers with
temporal encoding, pruning of memories no later frame can use, and checked
input handling. Hostile-input and cancel tests.

Self and cross attention with axial 2-D RoPE (keys tiled over memory frames,
object-pointer tokens left unrotated). Max abs error 2.6e-5.

Mask down-sampler, feature fuser and projection, sine position encoding,
occlusion embedding and bfloat16 rounding of stored memories. Max abs error
3.5e-6 on the memory features, 6e-8 on the position encoding.

Encode 5.0 s -> 3.4 s per 1024x1024 frame in release on 16 threads (fused
softmax, queries scaled before the matmul, flat 2-D linear layers); a click
on an encoded frame is about 120 ms. Reference tests unchanged.

A click on the synthetic image: mask logits within 1.1e-4 (range 11.6), IoU
head 1e-6, object score 2e-5, prompt embeddings 1e-7.

Weights loader with shape/finite validation (S2.10), patch embed, bicubic
positional embedding, window/global attention, query pooling. Reference test
(skips without weights): max abs error 2.6e-5 over all 12 blocks.

Synthetic Roto Brush clips with known mattes (movement, lighting change,
occlusion, leaving and re-entering) and a runner that compares the classical
engine with MobileSAM when installed. Needs no weights; SAM 2 plugs in later.

#1339 was written before ui-egui's integration tests became modules of one binary
(`tests/it/main.rs`), so its six test files landed at the top of `tests/`, each its own crate
and link. They move into `tests/it/` as modules; the a11y module's doc names the new path.

Since #2204, ci.yml runs `cargo xtask ci` through craft-common-actions' shared gate on every
pull request and push to main; gaps.md still listed "No CI gate on pull requests" as gap 4 and
in the Stability row.

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.

UPDATE_APP gains our accent (#e0368f, our colour in ArtCraft Launcher). The prompt draws it
on the UPDATE chip, the buttons and the What's new underline, and says "by ArtCraft"
(craft-update's default developer); #2646 gave it our icon.
craft-update is pinned to storytold/craft-libs main at 1065653e7 (#434).
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.

Timeline and Effect Controls value editors sent every write with the property's scrub merge
key, so two separate picks from a drop-down (or two check box toggles) on the same property
folded into one undo step. Drop-down, check box, layer and mask picks now record their own
step; scrubs and typed numbers still merge as before.
