+## 🔐 Security Highlights
+
+### Authentication
+```
+User Login:
+  Email + Password → JWT Access Token (15 min)
+                  → Refresh Token (30 days)
+
+Telegram Binding:
+  /start → Binding Code (10 min TTL)
+       → User clicks link
+       → Confirms account
+       → Receives JWT for bot
+       → Bot stores in Redis
+       → Bot uses for API calls
+```
+
+### Authorization
+```
+5 Roles: Owner → Adult → Member → Child → Read-Only
+25+ Permissions: Fully granular control
+Family Isolation: Strict data separation
+Resource Ownership: Can only edit own data
+RBAC Enforcement: In middleware + services
+```
+
+### Audit Trail
+```
+Every Action Logged:
+  ├─ Who did it (actor_id)
+  ├─ What happened (action)
+  ├─ When it happened (timestamp)
+  ├─ What changed (old/new values)
+  ├─ Why it happened (reason)
+  └─ Where from (IP address)
+```
+
+---
+

+- ✅ Approval workflows
+- ✅ Audit trails
+- ✅ Family isolation
+
+### DevOps Ready
+- ✅ Docker containerized
+- ✅ Health checks
+- ✅ Graceful shutdown
