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):

  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):

  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):

  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
