* CI: dev profile keeps line tables for workspace crates and no debug info for dependencies
* Control server tests: persistent_requests_and_slow_replies_outlive_the_idle_read_timeout no longer races the idle timeout
Each request (and the closing half-shutdown) reaches the socket before the
worker reads, so on a slow machine only the reply waits outlast the 100 ms
idle timeout, as the test intends. The idle test sends its input the same
way, and the no-frames test allows 5 s instead of 2 s to give up.
* CI: one integration-test binary per crate
Each crate's tests/*.rs become modules of tests/it/main.rs (51 test files
into 13 binaries, plus 6 that stay their own). Inner #![cfg] attributes
move to the mod lines. Files that change state for the whole process keep
a binary of their own: codecs jxl_tail_heap and raw sr2_heap (dhat global
allocator), gpu shutdown, shutdown_first and memory, ui-egui shutdown.
Docs, comments and the GPU probe name the new paths and targets
(--test it <module>::); the CI report names an it binary's skips after
the crate.
* CI: tests under nextest, doctests apart, one wasm check
xtask ci runs the tests with cargo nextest run --lib --bins --tests when
cargo-nextest is installed, else cargo test with the same targets and a
one-line notice; doctests run after them with cargo test --workspace --doc.
The heif and hardware GPU steps use the same runner. Examples stay out of
the test build (clippy --all-targets still checks them). Concurrent tests
under nextest follow the RUST_TEST_THREADS cap (NEXTEST_TEST_THREADS).
The wasm check is one cargo check --keep-going over the same crates, and
clippy runs with --keep-going.
* CI: tests run under cargo test by default, nextest with LIGHTCRAFT_NEXTEST=1 (per-process scene cache)
On an Intel Mac with an AMD Radeon Pro 5300M the Metal compiler crashes
on candle's mlx_gemm kernel, candle-metal-kernels panics on the compile
error, and the worker reported "the AI model failed unexpectedly" and
loaded the model on Metal again for every next job, so AI masks never
worked there.
The worker now retries a job that fails on the GPU (a panic or a candle
error) once on the CPU, after freeing the model. When that works, the
model stays on the CPU for the session and the job's outcome carries a
notice that segment_poll shows once; when the CPU fails too, the GPU
was not the cause and the next job uses it again. Missing or damaged
model files, render and remote-worker errors are not retried. Only
builds with a GPU path (macOS) retry; LIGHTCRAFT_GPU=0 and
LIGHTCRAFT_GPU_BACKEND=off now keep SAM 3 on the CPU from the start
(lightcraft_gpu::env_off_reason), like AI Denoise and the face models.
lightcraft-segment: Sam3::load_cpu, GPU_BUILD; text_logits returns the
crate's Error so Describe failures are classified like clicks.

Describe merged the detector's per-instance masks. Those stay near 0 even well inside what they
found: a sky came out about 87 % selected, a volleyball net about 70 %, a person about 94 %.
Two instances that touch both fade out where they meet, so a line showed between people standing
side by side.
- The detector's semantic head is now ported: semantic_projection over the pixel decoder, the
transformers implementation's semantic_seg. It matches the reference to about 1e-3, like the
instance masks. tools/sam3_reference.py writes it and the reference test checks it; older
reference files still pass.
- Each instance found (score above the threshold, as before) takes the semantic logits where it
is the strongest instance and near (above -4). The semantic mask is sure inside and runs on
across the boundary between two instances. Far from every instance nothing changes, so
Describe selects nothing it didn't find before.
On 16 prompts over three photos (a mountain landscape, two gym photos), the median coverage
inside each selection rises, e.g.:
- sky 0.87 -> 1.00
- mountains 0.81 -> 0.99
- net 0.71 -> 0.99
- floor 0.92 -> 1.00
- person 0.94 -> 0.99
Each selection gains 0 to 1.9 % of the photo at its soft rim and loses none.

libtest has no skipped status and hides the output of passing tests, so a
test that returns early without a GPU, a corpus file, a craft-fonts face or
a model passed silently. `lightcraft-testkit` (the testkit slot the layering
table already reserves, dev-dependency only, std only) adds
`skip!(Need, "reason")`: it prints the note as before and, when
LIGHTCRAFT_SKIP_LOG names a file, appends one JSON line (need, reason, test,
binary, file:line). Plain `cargo test` is unchanged. The 61 existing skip
sites use it.

The unknown-tab error now names every Settings tab (it missed AI Denoise after the
faces merge). lightcraft-sam3-worker (#359) only builds its server off wasm32, so
`cargo xtask wasm` passes again.

The worker binary gets the never-crash deny list and forbid(unsafe_code) like
every production crate root. docs/ai-masks.md spells out who can reach the
unauthenticated loopback listener.

Options::token_env (default none) replaces the hard-coded LIGHTCRAFT_SAM3_TOKEN, so a download of one model can
never send another model's token to its host. SAM 3 names its variable through lightcraft_segment::fetch::options().
The decision (non-empty, https, the host the download began at) is a small function with its own test.

The downloader in lightcraft-segment (mirrors, resume, pinned SHA-256, pure-Rust
HTTPS) was already generic apart from four SAM 3 constants. Move it to
crates/fetch (L0, native only) so other model features can use it without
depending on the SAM 3 inference code. lightcraft-segment keeps SAM3_FILES,
DEFAULT_MIRRORS, MIRRORS_ENV and wraps mirrors(); no behaviour change. The
downloader's 13 tests moved with it.

- The crate ports Apache-2.0-only Hugging Face transformers code: it is
now `license = "Apache-2.0"`, and every ported file carries the
modification notice Apache-2.0 §4(b) asks for.
- Weights::open checks every tensor's byte range (and the header)
against the file's length: a truncated or damaged download is an
error at load, never a short read later; regression test with
hostile offsets.
- fetch/: the model download, only when asked for. An ordered mirror
list (env LIGHTCRAFT_SAM3_MIRRORS, a mirrors file, DEFAULT_MIRRORS —
empty until LightCraft's CDN exists, TODO for the maintainer),
fallback to the next mirror, resume via Range, redirects, connect and
stall timeouts, cancel, size caps, exact size + SHA-256 (pinned from
tools/install-sam3.sh) before an atomic rename; damaged files are
deleted, HTTP error bodies never written.
- HTTP/1.1 client over std sockets + rustls with the RustCrypto provider
(rustls-rustcrypto) and webpki-roots: no ring / aws-lc-rs, nothing
compiled from C (no new `cc` users in the app's build graph).
- Tests against a local TcpListener server (no internet): fallback,
redirects, chunked bodies, resume, 416, hash mismatch, too much data,
stalls, cancel.
- *.safetensors are gitignored.

AI masks from Meta's SAM 3, run in LightCraft itself: a new
`lightcraft-segment` crate ports the Hugging Face transformers
implementation (Apache-2.0) to candle, on the GPU through Metal on macOS
(CPU elsewhere), with no C/C++ and no `unsafe`.
- Object: click to include, ⌥-click to leave a part out (SAM 3's
interactive prompt encoder + two-way mask decoder).
- Describe: a text prompt selects every instance ("sky", "the red car";
"car, road" merges several) via the CLIP text encoder and DETR detector.
- Both as new masks and as Add / Subtract / Intersect components; + / −
buttons under the selected mask combine selections.
- The segmentation is stored with the mask (288² quantized logits, ~10-30
KB), so renders, exports and the web build never need the model.
- A zoomed-in detail pass (background, ~5 s on an M4 Pro) re-segments the
area around a selection from a sharper source: 5-10x finer edges on
small objects.
- Per-selection Edge slider (hard ↔ soft); hovering a mask in the list
shows it in red (the always-on overlay is now off by default, O toggles).
- The engine feature `sam` (on in the desktop app) gates the model; the
image is encoded once per photo in the background, clicks take ~35 ms.
- Weights are not bundled (SAM License): tools/install-sam3.sh / .ps1
download and verify facebook/sam3; docs/ai-masks.md.
- Clearer errors (missing file, missing model) and a stderr logger in the
app (LIGHTCRAFT_LOG=info).
candle is pinned at 0.9.2: later releases make candle-core depend on
tokenizers with the Oniguruma C library. Every stage is checked against
the Python reference (tests/reference.rs, tools/sam3_reference.py): on
Metal the backbone matches to 7e-5 relative error, masks to ~5e-5.
