# Goal-6-Task-3 Work Log

## Task Summary
Implement RBAC integration with boundary enforcement and enhanced inheritance as specified in:
- Goal-6-execution-plan.md section 3.1
- security-requirements.md

## Implementation Plan
1. Add BoundaryType enum (GLOBAL, INTERNAL, RESTRICTED)
2. Enhance Role class with boundary enforcement
3. Strengthen ADMIN role inheritance
4. Improve circular inheritance validation
5. Add unit tests for new functionality

## Initial Implementation
[2025-05-04 16:36] Starting RBAC boundary enforcement implementation
### [5/4/2025, 4:38 PM] RBAC Boundary Validation Enhancement

Implemented stricter boundary inheritance rules in `validate_boundary()`:
- Added explicit checks for INTERNAL and RESTRICTED role inheritance
- INTERNAL roles can no longer inherit from RESTRICTED roles
- RESTRICTED roles can only inherit from GLOBAL roles
- Maintained existing boundary hierarchy validation
- Updated error messages to be more specific

Changes verified by:
1. Confirming modified function matches requirements
2. Checking error message clarity
3. Ensuring backward compatibility with existing valid inheritance patterns

Next steps:
- Conductor to verify implementation against security requirements
- Checker to validate through test cases
