+# Branch Locking System Implementation Plan
+
+   ## Core Requirements
+   1. Role-based locking permissions
+   2. Lock state indicators in UI
+   3. Lock override protocols
+   4. Audit logging for lock events
+   5. Maximum lock duration: 48hrs
+
+   ## Technical Integration
+   - **Model Extensions**  
+     Enhance `VersionBranch` (line 14):
+     ```python
+     class VersionBranch(models.Model):
+         lock_status = models.JSONField(default=dict)  # {user: ID, expires: datetime}
+         lock_history = models.JSONField(default=list)
+     ```
+
+   - **Manager Methods**  
+     Add to `BranchManager` (line 141):
+     ```python
+     def acquire_lock(self, branch, user, duration=48):
+         """Implements lock with timeout"""
+     
+     def release_lock(self, branch, force=False):
+         """Handles lock release with permission checks"""
+     ```
+
+   - **UI Components**  
+     Update `VersionControlUI` interface (line 58):
+     ```typescript
+     lockState: {
+       isLocked: boolean;
+       lockedBy: UserRef;
+       expiresAt: Date;
+       canOverride: boolean;
+     };
+     ```
+
+   ## Security Considerations
+   - Permission escalation prevention
+   - Lock expiration enforcement
+   - Audit log integrity checks
+   - Session validation for lock holders
+
+   ## Phase Plan
+   1. **Week 1**: Locking backend implementation
+   2. **Week 2**: Permission system integration
+   3. **Week 3**: UI indicators & controls
+   4. **Week 4**: Audit system & testing
