runtime.ts: the runtime is pinned in a compiled constant (version, URL, size,
sha256). The archive is streamed to a .partial file while it is hashed,
continued with a Range request, retried at most 3 times, and the hash is
compared before anything is unpacked; a mismatch deletes the file. It is
unpacked with /usr/bin/tar into a temporary folder and renamed.
The supervisor runs the runtime as a non-detached child with an environment
built from an allowlist by the pure runtimeEnv(), on a port chosen once by
binding. It restarts the child at most 3 times, stops it with SIGTERM, adopts
or replaces its own orphan on the port and answers port-in-use for any other
listener. parseInferenceComputeTotal() reads the device total the runtime
logs when it starts. Under vitest nothing spawns or fetches.
ollama-client.ts: the pull is parsed incrementally by a pure parser (a 23 GB
pull is about 1.4 million lines), with up to 5 retries on an error line or a
cut stream. verifyModel() loads the model with one tiny chat, checks what the
runtime reports (all on the GPU, the chosen context) and makes one tool
probe; each failure is a code.
developer-tools.ts: only /usr/bin/xcode-select -p, bounded, darwin only.
