Release Integrity

ZapTrace release integrity relies on GitHub Releases, workflow logs, SBOM generation, and artifact attestations.

What to verify

For an official release, verify:

  1. The release tag matches the package version.
  2. The release was created by the repository release workflow.
  3. Release assets are associated with the release tag.
  4. SBOM/provenance or attestation artifacts are present when the workflow produced them.
  5. The changelog describes user-visible and security-relevant changes.

Verify with GitHub CLI

gh release view v0.3.0 --repo oaslananka/zaptrace
gh release download v0.3.0 --repo oaslananka/zaptrace --dir /tmp/zaptrace-release

Verify artifact attestation

When GitHub artifact attestations are available, use GitHub's attestation verification tooling for the release assets. The expected repository identity is:

oaslananka/zaptrace

The expected workflow is the repository release workflow under .github/workflows/release.yml.

Hashes and checksums

Recent release automation generates a SHA256SUMS manifest for release artifacts. Compare local artifact hashes against that manifest using sha256sum --check SHA256SUMS. If an older release does not include a checksum manifest, rely on GitHub release transport security plus available attestations/SBOM and prefer upgrading to a release with checksum evidence.

Non-claims

Release integrity verifies artifact origin and tamper evidence. It does not prove that generated hardware is safe, manufacturable, compliant, or correct.

Version and tag identity

The active package/runtime/Rust line and future tag policy are defined in Version Policy. A future release tag must be an annotated v<package-version> tag and resolve to the exact checked-out release commit. The historical v0.3.0 lightweight tag is grandfathered evidence, not the model for future releases. Cryptographic tag verification is not currently enforced because no reviewed maintainer trust root is committed; release reports must not claim a verified signature.
