supply-chain-security

Software supply chain security reference for OpenSSF Scorecard, SLSA, Sigstore, SBOM, and posture/backlog taxonomies.

Supply Chain Security

This skill packages the durable software supply chain security (SSSC) reference material: open-standard catalogs, the combined capabilities inventory, and the classification taxonomies used to assess a repository's posture and turn gaps into prioritized work items.

When to use

Use this skill when you need to:

Assess a repository against the 27 combined supply chain capabilities from hve-core and physical-ai-toolchain.
Map posture against OpenSSF Scorecard, SLSA v1.0, OpenSSF Best Practices Badge, Sigstore (cosign), or NTIA SBOM minimum elements.
Classify a gap by adoption category, effort size, or qualitative concern level.
Derive work item priority and execution order from Scorecard risk levels.
