Verifying This Build

Every release is published via PyPI Trusted Publishing with PEP 740 build attestations. No long-lived API tokens. The wheel you pip install is byte-identical to what GitHub Actions built from a tagged commit.

To verify a release: visit the project page on PyPI, click Download files, and check the Provenance section under each artifact. You'll see the sigstore attestation, the GitHub workflow run, and the exact commit SHA — all logged to the public Sigstore transparency log for independent verification.

This answers "is the wheel what's in the source?" — the cryptographic chain proves this wheel was built from ClassiFinder/cfsniff at the tagged commit, by a GitHub-hosted runner, and cannot be tampered with after the fact.
