# Goal-2 (RBAC Implementation) Execution Plan

## Task Sequence
1. Task-1: RBAC Core Implementation
2. Task-3: Negative Test Implementation (parallel with Task-1)
3. Task-2: TLS-RBAC Integration
4. Task-4: Audit Logging Integration

    D --> E[Task-4]
```

## Quality Checkpoints
1. After Task-1: Security review of RBAC core
2. After Task-2: Integration test validation
3. After Task-4: Final security audit

## Iteration Plan
1. **Initial Implementation** (Tasks 1-3)
   - Focus: Core functionality
   - Duration: 5 days
   - Exit Criteria: 90% unit test coverage

2. **Hardening Phase** (Tasks 3-4)
   - Focus: Edge cases and audit logging
   - Duration: 3 days
   - Exit Criteria: 100% negative test coverage

3. **Final Validation**
   - Focus: Security review
   - Duration: 2 days
   - Exit Criteria: Security team sign-off

## Risk Mitigation
- **Risk**: TLS-RBAC integration complexity
  - **Mitigation**: Early prototype in Task-1
- **Risk**: Negative test coverage
  - **Mitigation**: Dedicated Task-3 parallel track
