+### Phase 5 — Analytics Enhancement (Complete)

+- Tabbed analytics page: Overview, Coverage, Flow Quality, PSA
+- Coverage heatmap: domain grid with color-coded cells (resolution/escalation/guided rates, flow count)
+- Domain-to-flow mapping via category cross-reference
+- Flow quality scoring endpoint: quality_score = (success_rate * 0.5) + (guided_rate * 0.3) + (recency * 0.2)
+- Flow quality table: sortable, top performers (emerald), needs attention (rose), mini score bars
+- Flow usage tracking: usage_count, success_rate, last_matched_at wired into session matching + resolution
+- PSA activity logging: psa_activity_logs table, wired into documentation push service
+- Enhanced PSA metrics: time entries, hours logged, push success funnel, daily trend chart
+- 13 new backend tests for coverage and flow quality endpoints

-### Immediate (Phase 5 — Analytics + Polish)
-
-- AI-enhanced analytics dashboard (MTTR trends, resolution rates, knowledge coverage heatmap)
-- FlowPilot accuracy metrics (guided vs exploring vs discovery drill-downs)
-- Flow quality scoring (success rate, usage frequency, last-used recency)
-- Domain-to-flow mapping for coverage analysis
-- PSA time entries/hours tracking
