| ------------------------- | --------------------------------------------------------------------------------------- |
| Vulnerability Scanning    | Static and dynamic code analysis, manual inspection                                     |
| Fuzz Testing              | Randomized stress tests for overflow and invalid inputs                                 |
| Threat Modeling           | NIST-aligned threat analysis covering data confidentiality, integrity, and availability |
| Access Control Validation | Testing `ensure_signed`, `ensure_root`, and multi-sig approval processes                |
| Compliance Mapping        | Cross-referencing controls with FCA regulatory principles                               |
