+Run the repository audit workflow by using the shared audit script.
+
+Requirements:
+
+- Prefer `resources/scripts/audit-copilot-usage.sh` over ad hoc searching.
+- Keep the audit itself read-only.
+- Review `audit-summary.md`, `candidates-report.tsv`, `selection-manifest.tsv`, and `pattern-details/`.
+- Recommend promotion only for portable resources; keep machine-specific or
+  repo-specific patterns in audit notes.
