Guided Labs
Build a locked dependency and hermetic pipeline, produce SBOM and attestations, sign and verify an artifact, inject a workflow substitution, enforce admission policy, rotate workload identity, and detect platform drift.
Required evidence
Submit authorized pipeline configuration, inventory, artifact and provenance identifiers, verification output, injected failure, policy decision, remediation, and residual risk. A green build without trustworthy identity and traceability does not pass.
Oral defense
Trace source to runtime, explain which claim each artifact proves, demonstrate rejection of a substitution, and state the response when trust material is revoked.
