same-run evidence artifact. The caller supplies immutable identifiers and digests, but the trusted workflow independently verifies them before minting an OIDC token or invoking `actions/attest@59d89421af93a897026c735860bf21b6eb4f7b26`. + +The boundary has two jobs: + +1. `verify-evidence-artifact` has only `actions: read` and `contents: read`. It confirms the exact artifact ID, name, digest, workflow-run ID, expiry state, source repository, source SHA, six-file cardinality, SHA-256 handoff, strict JSON, CycloneDX specification 1.7 identity, and root distribution binding. +2. `attest-exact-artifacts` receives `id-token: write`, `attestations: write`, `artifact-metadata: write`, and `contents: read` only after the first job succeeds. It downloads the same immutable artifact ID, repeats the data-only verification, and signs the exact wheel and source distribution separately. + +Both jobs load the verifier from `${{ job.workflow_repository }}` at `${{ job.workflow_sha }}` with persisted Git credentials disabled. Caller-controlled source is never checked out in the signing boundary. Downloaded files are treated as inert bytes: the workflow does not import, install, build, test, execute, source, or unpack them. + +The handoff contains exactly: + +- one wheel; +- one CycloneDX 1.7 wheel SBOM; +- one source distribution; +- one CycloneDX 1.7 source-distribution SBOM; +- `source-identity.json`; and +- `checksums.sha256`. + +The checksum file binds the other five files. Externally supplied digests bind all six files, including the checksum file itself. Each SBOM root component must name the exact distribution and include its exact SHA-256 digest. + +## Exact-head lifecycle + +```mermaid +flowchart LR + A[Caller builds exact source SHA] --> B[Caller creates wheel, sdist, two SBOMs] + B --> C[Caller seals six-file artifact] + C --> D[Read-only metadata and data verification] + D --> E[Credentialed job repeats verification] + E --> F[Wheel SBOM attestation] + E --> G[Sdist SBOM attestation] + F --> H[Online signer/predicate/source verification] + G --> H + H --> I[Sigstore bundles and trusted root export] + I --> J[Offline verification artifact] +``` + +A caller must pass its exact `source_repository`, 40-character `source_sha`, same-run artifact ID, artifact name, artifact digest, filenames, SHA-256 digests, CycloneDX schema URI, and SBOM predicate type. The workflow rejects a caller repository or source SHA that does not match the live GitHub run context. + +The verifier emits deterministic compact JSON containing the verified source identity, predicate, schema, filenames, sizes, and hashes. It publishes the manifest atomically and rejects an output symlink. + +## Offline verification + +The signing job preserves both Sigstore bundles, a fresh `trusted_root.jsonl`, and the deterministic verified-handoff manifest. An operator imports the distribution, its matching bundle, the trusted root, and GitHub CLI into the offline environment, then runs: + +```bash +gh attestation verify path/to/distribution \ + --repo OWNER/REPOSITORY \ + --bundle path/to/attestation.json \ + --custom-trusted-root path/to/trusted_root.jsonl \ + --signer-repo ContextualWisdomLab/.github \ + --signer-workflow ContextualWisdomLab/.github/.github/workflows/exact-artifact-sbom-attestation.yml \ + --source-digest EXACT_SOURCE_SHA \ + --predicate-type EXPECTED_SBOM_PREDICATE +``` + +Generate a new trusted root whenever new signed material enters an offline environment. A previously exported root cannot reveal revocation or later key rotation that occurred after export. + +## Incident recovery and rollback + +1. Disable the caller release workflow without changing or deleting existing evidence. +2. Preserve the failed run ID, artifact ID, artifact digest, source SHA, verification output, and attestation bundles. +3. Determine whether the defect is in build output, SBOM generation, the sealed handoff, trusted verification, or signing. +4. Revoke or delete an invalid GitHub attestation only after preserving a forensic copy and documenting affected consumers. +5. Correct the source or workflow through a protected pull request. Never overwrite a distribution while retaining its old filename or digest claim. +6. Rebuild from a new exact source SHA, generate new artifacts and SBOMs, and rerun the complete verification and attestation lifecycle. +7. Publish an incident note identifying invalid subjects, replacement subjects, and consumer actions. + +Rollback means restoring a previously reviewed workflow version and producing new signed material. It does not mean reusing an old attestation for newly built bytes. + +## Claims deliberately not made + +- An SBOM attestation does not prove that the software is vulnerability-free, malware-free, correct, safe, or fit for a particular purpose. +- This workflow does not claim SLSA Build Lx (v1.2). It supplies a narrow SBOM authenticity and exact-subject binding control, not a complete build provenance level. +- CycloneDX conformance does not prove that the component inventory is complete or semantically correct. +- A valid signature does not make caller-provided predicate content trustworthy by itself; the trusted reusable workflow and verifier are the policy boundary. +- Offline verification cannot detect revocation or trusted-root rotation that happened after the trusted root was exported. +- `artifact-metadata: write` does not imply that a non-registry distribution has been published, deployed, or approved for release. + +## References + +CycloneDX Core Working Group.
