SAM 2's instance now reads wgpu's environment variables, as the render context's does, so a driver such as
Mesa's Dozen (WGPU_ALLOW_UNDERLYING_NONCOMPLIANT_ADAPTER=1) is visible to it, and WGPU_POWER_PREF applies.
An adapter without compute shaders is refused before a device is made on it, so the CPU takes over with one
line instead of a validation error per kernel. The refused adapter is kept for the life of the process, as
the device on it was: dropping it crashed the tests on WSL2's GL driver. Gpu::shared no longer repeats
"SAM 2 compute:" in its errors.
A run reads the project, edits it and writes the whole file back, so two
at once silently dropped the edits of whichever saved first. A run that
saves over the file it opened (--save, or --save-as the same file) now
holds an OS lock on `.<name>.lock` next to the project from before its
read until it exits. The next run says so on stderr, waits, then edits
what the first one saved. Ported from filmcraft-cli
(storytold/filmcraft#3926).
The OS drops the lock however the process ends, so a crash leaves nothing
stale. If the lock can't be taken the run warns and saves as it did
before. A missing project stops the run before it opens anything, with
the same error opening gives, so a project created in between is never
saved without the lock. The desktop app and `mcp` don't take this lock.
camera.solveStatus said `solved: true` for any stored solve, but the solver
keeps the frames it cannot resect as unsolved and interpolates the camera
there. `solved` now needs every frame, the same check camera.exportBlender
makes, and `partial` marks a solve with gaps, next to `solvedFrames`.
Offset Paths' Amount, Line Join, Miter Limit, Copies and Copy Offset,
and Zig Zag's Size, Ridges per segment and Points reported their
internal ids as matchName, so property("ADBE Vector Offset Amount") and
the other documented names returned null. They now report and resolve
by ADBE Vector Offset Amount, Line Join, Miter Limit, Copies and Copy
Offset, and ADBE Vector Zigzag Size, Detail and Points. Lookups by
display name and internal id still work.
The command checks look at the paths an agent gives, but a project it opens or
imports from a read root names its own footage, which was read wherever it is
when the project rendered: render_frame returned its pixels.
Backend::confine now wraps a headless session's footage and services:
ConfinedFootage reads frames, audio, aux channels, models and vector frames
only for footage inside the read roots (problem() says why the rest shows
nothing), and ConfinedServices checks read_file, exists, stamp, list_dir and
is_dir the same way. Writes are left to the command checks.
Test: automation_roots_confine_the_footage_a_project_names covers an absolute
path, `../`, a linked file and a linked folder, each opened and imported.

A shortcut belongs to the application, a panel or a context (editing text, a paint or
camera tool active, a mask selected). The narrowest active scope runs a chord: an active
context, the focused panel, the panel sharing its shortcuts (Timeline and Composition),
the application. A context's shortcuts never run outside it.
- shortcuts.rs: scope table for engine commands and menu entries, scope_rank,
scope_label; UiCommand can state its scope.
- Conflicts: the same chord in two scopes is an override (both keep working), reported
with overrides: true; shortcuts.conflicts lists same-scope pairs only.
- Scoped now, keys unchanged: Remember / Apply Interpretation and Delete Without
Confirmation (Project), Duplicate Render Item (Render Queue).

Adds Swedish (Svenska) as an interface language in the menu, panel and
effect catalogs, written from the English source. The effect rows are
partial like Japanese and Georgian: an effect without a Swedish row draws
its English name, so a new effect does not block other PRs (#2244).

bench --roto per size: no larger size tracked better on the synthetic clips and
Large lost the object after it re-entered; the hints say what was measured.
The bar shows the current object's stroke count and can remove its strokes.
An env-gated test runs the in-app download of a size.

Strokes carry an object (0 for older projects, nothing written for 0). The
tracker follows every object in one pass and the mattes are united; the
confidence of a frame is the least sure object's. Object picker in the Layer
panel's bar; roto.options/stroke/clearStrokes/status take or report objects.

Hiera configs and size detection from the weights, registry entries pinned to
commits with verified SHA-256, the loader picks the size by checksum. The GPU
encoder submits once per block so Large fits in memory, and uploads no longer
panic on a lost device. Reference tests run per size on the CPU and GPU.

Simulated user paints a foreground stroke through the true object and a background
stroke on the biggest false positive on the first frame under IoU 0.9, up to 6
rounds. SAM 2 needs none on every clip; classical and MobileSAM need more than 6 on
occlusion and re-entry. All trackers now take strokes on any frame.

Memory attention (1.8e-5 vs PyTorch) and the memory encoder (2.6e-6) as wgpu kernels,
convolution and layer-norm+GELU kernels, VideoModel::load_auto picks the GPU when
there is one (EFFECTCRAFT_SAM2_DEVICE overrides) and falls back to the CPU on any GPU
error; disable_gpu switches it off mid-clip. One process-wide device (several at once
crashed the Vulkan loader). A tracked frame: 4.3 s CPU, 0.7 s on the RX 7900 GRE.
Clips tracked on the GPU match Sam2VideoModel (worst logit error 0.0032).

Candle adds a bias on one thread; the Linear layers now add it (and apply GELU
for the MLP in) in one parallel pass. Encode 2.4 s -> 2.1 s, memory attention
2.4 -> 2.3 s; reference tests unchanged. gpu_matmul example: a tiled WGSL
matmul on the RX 7900 GRE reaches 1.9-3.6 TFLOPS against 0.16-0.47 for the CPU.
