Change Approval Workflow Implementation Plan

Core Requirements

1. Configurable approval stages
2. Role-based reviewer assignments
3. Parallel vs sequential approvals
4. Audit trail of decisions
5. Integration with existing locks/comments

Technical Integration

• State Machine
  Extend StateMachine interface:

  interface ApprovalStateMachine extends StateMachine {  
      currentStage: ApprovalStage;  
      requiredApprovers: UserRef[];  
      overridePolicy: 'majority' | 'unanimous';  
  }  
  

• Model Extensions
  Enhance ChangeSet (line 7):

  class ChangeSet(models.Model):  
      approval_state = models.JSONField(default=list)  # [{stage: 1, approvers: [...]}]  
      approval_history = models.JSONField(default=list)  
  

• API Endpoints
  Add to VersionControlViewSet (line 128):

  @action(detail=True, methods=['post'])  
  def submit_for_approval(self, request, pk=None):  
      """Transition change set to approval state"""  
  

Security Considerations

• Approval chain validation
• Non-repudiation requirements
• Conflict resolution protocols
• Approval delegation safeguards

Phase Plan

1. Week 1: State machine implementation
2. Week 2: Approval UI components
3. Week 3: Integration testing
4. Week 4: Deployment safeguards
