# Contributing Contributions are welcome for runtime portability, deterministic validation, documentation, benchmark reproducibility, and the sandboxed demo. Before opening a pull request: 1. keep model proposals separate from external authorization and execution; 2. add a focused regression test for behavior changes; 3. run `pytest -q`, `ruff check .`, `ruff format --check .`, and `python scripts/verify_public_release.py`; 4. do not add raw datasets, official or private labels, model checkpoints, credentials, internal infrastructure records, or unverified benchmark claims; and 5. preserve all upstream licenses and attribution. Benchmark changes must identify the dataset revision, split construction, metric, evaluator, decoding settings, model revision, and sample-level evidence needed to reproduce the claim.
