+
+**Daily Review Checklist:**
+1. Review audit logs: PluralisticDeliberationOrchestrator cultural_sensitivity_check
+2. Identify false positives (flagged but culturally appropriate)
+3. Identify false negatives (missed culturally insensitive content)
+4. Analyze patterns across media responses and blog posts
+5. Update detection patterns in assessCulturalSensitivity() if needed
+
+**What to Look For:**
+- Western-centric language that was APPROPRIATE for the audience
+- Indigenous exclusion that was APPROPRIATE for the context
+- Culturally insensitive content that was NOT flagged
+- New patterns emerging from real-world usage
+- Feedback from human reviewers on flagged content
+
+**Success Metrics:**
+- < 10% false positive rate (flagged but appropriate)
+- < 5% false negative rate (missed insensitive content)
+- Consistent improvement in detection accuracy
+- Human reviewer confidence in AI flagging
+
+**Update Process:**
+1. Document findings in docs/governance/CULTURAL_SENSITIVITY_REFINEMENTS.md
+2. Update patterns in PluralisticDeliberationOrchestrator.service.js
+3. Test new patterns with historical examples
+4. Commit changes with rationale
+5. Monitor impact in next review cycle
+
+**Context:**
+Phase 1: Detection & flagging (COMPLETED)
+Phase 2: UI & workflow (IN PROGRESS)
+Phase 3: Learning & refinement (THIS REMINDER)
