Every release ships verifiable supply-chain provenance: Sigstore-signed SLSA build-provenance attestations on the wheel, sdist, and container image; PEP 740 attestations on the PyPI upload; and a CycloneDX SBOM — so you can prove the artifact you installed was built from this repo. See Provenance & supply chain.

A research tool is only as trustworthy as the chain from its source to the binary you run. Every release of this server ships cryptographically verifiable supply-chain evidence, all generated in CI from the tagged commit:
| Guarantee | What it proves | Where it is produced |
|---|---|---|
| SLSA build provenance (wheel + sdist) | the published distributions were built by this repo's publish.yml from the released tag, not hand-uploaded | publish.yml — actions/attest-build-provenance (build job) |
| SLSA build provenance (container image) | the ghcr.io image digest was built by this repo's docker.yml | docker.yml — actions/attest-build-provenance, push-to-registry (lines 141–147) |
| PEP 740 attestations | the PyPI upload itself carries Sigstore-backed attestations under Trusted Pub |
