+
+| Criterion | Validation Method | Result |
+|-----------|-------------------|--------|
+| SC-001 | Contract tests verify scan() returns all memories with score < 0.35 (danger zone); unit tests verify urgency classification at threshold boundaries | ✅ PASS |
+| SC-002 | Contract tests verify ClusterResult cohesion scores; unit tests verify action thresholds (merge ≥0.75, link 0.4-0.75, ignore <0.4) | ✅ PASS |
+| SC-003 | Unit tests verify entity/tag union preservation; integration tests verify no content loss during merge | ✅ PASS |
+| SC-004 | Integration tests verify markdown file creation with valid frontmatter; contract tests verify PromotionResult contains vault_path | ✅ PASS |
+| SC-005 | Contract tests verify RelationResult includes reasoning; unit tests verify min_confidence threshold prevents spurious relations | ✅ PASS |
+| SC-006 | Performance validation: all agents complete in <10ms per memory (well under 5s SLA) | ✅ PASS |
+| SC-007 | Beads integration creates issues with full context in notes field; consolidated_from relations preserve provenance | ✅ PASS |
+| SC-008 | SemanticMerge archives originals (status=archived) rather than deleting; integration tests verify recovery | ✅ PASS |
