+- Milestone audit now cross-references three independent sources (VERIFICATION.md + SUMMARY frontmatter + REQUIREMENTS.md traceability) instead of single-source phase status checks
+- Orphaned requirements (in traceability table but absent from all phase VERIFICATIONs) detected and forced to `unsatisfied`
+- Integration checker receives milestone requirement IDs and maps findings to affected requirements
+- `complete-milestone` gates on requirements completion before archival — surfaces unchecked requirements with proceed/audit/abort options
+- `plan-milestone-gaps` updates REQUIREMENTS.md traceability table (phase assignments, checkbox resets, coverage count) and includes it in commit
+- Gemini CLI: escape `${VAR}` shell variables in agent bodies to prevent template validation failures
