Add an SBOM Policy Enforcement (SscaEnforcement / CdSscaEnforcement) step to an existing Harness pipeline to verify SBOM attestations and apply OPA SBOM policy sets. Supports CI, Security, and CD (Deployment) including CI-only pipelines — if no Deploy stage exists, add one via Phase 3b (service, environment, infra, containerized step group) then place CdSscaEnforcement before deploy. Supports container images and repositories from Artifact Registry, Third-Party registries (docker, ECR, GCR, GAR, ACR), and Git. Matches Pipeline Studio SBOM Policy Enforcement UI. Only works with existing pipelines (may append a Deploy stage). Use when asked to enforce SBOM policies, add SBOM policy enforcement, verify SBOM attestation in pipeline, or block non-compliant components. Trigger phrases: enforce SBOM, SBOM policy enforcement, SBOM policy step, verify SBOM policy, SscaEnforcement, add policy enforcement after SBOM.
