+## 🔒 Security Features
+
+### Per-Route RBAC
+```
+✅ doctor.read       → GET /patients, /appointments, /prescriptions, /surgeries
+✅ doctor.read       → GET patient details, lab results
+✅ emr.read/write    → EMR access (blocked for non-doctors)
+✅ prescription.*    → Prescription lifecycle management
+✅ appointment.*     → Appointment updates (doctors can only update own)
+✅ lab.read/order    → Lab test viewing and ordering
+✅ surgery.*         → Surgery scheduling
+```
+
+### Audit Trail
+- ✅ Every action logged with `actorId`, `action`, `resource`, `resourceId`
+- ✅ Before/after data captured for updates
+- ✅ Meta information (count, filters, patient names) logged
+
+### Data Integrity
+- ✅ Doctor can only access own patients (via appointments)
+- ✅ Cannot update dispensed prescriptions
+- ✅ Cannot update completed appointments (soft enforcement)
+- ✅ Cross-doctor access blocked with 403
+- ✅ All user input trimmed and validated
+
+---
+
+## 🗄️ Database Schema Updates
+
+### Added Fields
+- `Prescription.pharmacistNotes` (String?, nullable)
+- `LabTest.instructions` (String?, nullable)
+- `LabTest.priority` (String, default: "ROUTINE")
+- `Surgery.anesthesiologist` (String?, nullable)
+
+### Relationships
+- Doctor → Appointment (1:N)
+- Doctor → Prescription (1:N)
+- Doctor → Surgery (1:N)
+- Patient → All records via foreign keys
+
+---
+

+
+## 🚀 What's Next - Phase 2
+
+1. **Frontend Components**
+   - Doctor Dashboard with real API calls
+   - Patient list with search/filter
+   - Patient detail view
+   - Forms for EMR, prescriptions, lab orders, surgeries
+
+2. **Frontend-Backend Integration**
+   - Connect dashboard to `/api/doctor/patients`
+   - Connect forms to respective POST/PATCH endpoints
+   - Error handling & user feedback
+   - Loading states
+
+3. **API Validation** (Recommended)
+   - Run integration tests
+   - Test permission checks with different roles
+   - Verify audit logs are created
+   - Test database transaction rollbacks
