+**2,800+ lines | Complete Alert System Documentation**
+
+**Comprehensive Guide Covering:**
+- **Alert System Philosophy**: Context over noise, smart prioritization, user agency
+- **Three-Tier Enrichment Strategy**:
+  - Tier 1: ALERTS (Full enrichment, 500-800ms) - Actionable items requiring user intervention
+  - Tier 2: NOTIFICATIONS (Lightweight, 20-30ms, 80% faster) - Informational updates
+  - Tier 3: RECOMMENDATIONS (Moderate, 50-80ms) - Advisory suggestions
+- **Multi-Factor Priority Scoring** (0-100):
+  - Business Impact (40%): Financial consequences, affected orders
+  - Urgency (30%): Time sensitivity, deadlines
+  - User Agency (20%): Can user take action?
+  - AI Confidence (10%): Prediction certainty
+- **Alert Escalation System**: Time-based priority boosts (+10 at 48h, +20 at 72h, +30 near deadline)
+- **Alert Chaining**: Causal relationships (stock shortage → production delay → order risk)
+- **Deduplication**: Prevent alert spam by merging similar events
+- **18 Custom React Hooks**: Domain-specific alert/notification/recommendation hooks
+- **Redis Pub/Sub Architecture**: Channel-based event streaming with 70% traffic reduction
+- **Smart Actions**: Phone calls, navigation, modals, API calls - all context-aware
+- **Real-Time SSE Integration**: Multi-channel subscription with wildcard support
+- **CronJob Architecture**: Delivery tracking, priority recalculation - why cronjobs vs events
+- **Frontend Integration Patterns**: Complete migration guide with examples
+
+**Business Value:**
+- 80% faster notification processing (20-30ms vs 200-300ms)
+- 70% less SSE traffic on domain pages
+- 92% API call reduction (event-driven vs polling)
+- Complete semantic separation of alerts/notifications/recommendations
+
