Repository instructions

Run commands from the repository root in an isolated environment installed with pip install -e '.[test]'.
Validate changes with pytest -q, (cd results/raw && sha256sum -c SHA256SUMS), and python benchmarks/verify_published.py.
Benchmark outputs are create-only. Use a new output path and expose exactly one CUDA GPU per scorer process.
Do not change headline claims or results/phase1-summary.json without committing the supporting row-level evidence, regenerating the relevant raw report, updating results/raw/SHA256SUMS, and updating the method/results text.
Preserve exact model and source revisions. Use benchmarks/fetch_sources.py only for its listed redistributable inputs; do not commit model weights, caches, or third-party raw records.
webgpu-demo/ is static and has no build step. Preserve _headers, runtime version pins, browser-only inference, and the explicit probability limitations.
