- Reviewed security requirements from symphony-core.md
  - Must implement AES-256 encryption for memory operations
  - Audit logging requirements apply
- Examined security/encrypt.py
  - Currently only handles TLS configuration
  - Need new AES-256 implementation for memory encryption
- Next steps:
  - Design interface specification document
  - Implement abstract base class with encryption support
### 2025-05-02 19:55:00
- Implemented abstract base class in security/memory.py
  - Integrated AES-256 encryption from security/encrypt.py
  - Added RBAC checks using rbac_engine.py
  - Implemented audit logging for all operations
- Verified all interface requirements are met:
  - CRUD operations with proper encryption
  - Security baseline compliance
  - Documentation complete in specs/memory-interface.md
- Task complete, ready for review
