# Supply Chain Guard

> Resolve prod-closure dependency drift safely and catch tag-along dependencies. Reproduces the release-gate scan (supply-chain:scan:check), classifies each path-keyed prod INSTANCE as clean / roll-forward / tag-along / source-anomaly / integrity-mismatch / dropped against a committed ledger + baseline, researches advisories with exa, gets independent cross-LLM validation, and writes per-dependency contracts before any ledger change. Use when release-security-audit.sh fails with a supply-chain verdict (exit 2 or 3), to sweep drift before cutting a release, or to audit whether a new package slipped into the prod tree.
