Two CI failures, unrelated except that both were mine. **The test binary faulted under parallel threads.** Every GPU test opened its own `GpuContext`, and `cargo test` runs on as many threads as there are cores — so a full run asked the driver to bring up a dozen Vulkan devices at once and died with SIGSEGV. Serially it passed, which made it look like flakiness rather than a fault in the harness. One device now, behind a `OnceLock`: a `GpuContext` is an `Arc<Device>` and an `Arc<Queue>`, so sharing it is a refcount, and the losers of the race block until the winner is done. 416 tests now pass in parallel, in half the time twenty-six devices took. **`lfs: true` on the checkout made the checkout fail.** The intent was right — the model is in LFS, a plain checkout writes a 133-byte pointer, and the build script panics on it — but on this server `git lfs fetch` is rejected at `/info/lfs/objects/<oid>` with a client error: the credential `actions/checkout` installs for git is not one the LFS endpoint accepts. So a fetch problem presented as a checkout problem and took the whole job with it. The object is on the server; a clean clone over SSH with `git lfs install --local` pulls all 11 MB of it. It is now its own step with an explicit token, and `continue-on-error` so a credential problem cannot masquerade as a broken checkout — if it fails, the build still runs and fails with the build script's own message, which names the real problem.
