- Evidence: File metadata for test evidence (stored in MinIO)
- IntelItem: Threat intelligence items linked to techniques
- AuditLog: System-wide audit trail with JSONB details
Enumerations:
- TechniqueStatus: not_evaluated, in_progress, validated, partial, etc.
- TestState: draft, in_review, validated, rejected
- TestResult: detected, not_detected, partially_detected
Services:
- audit_service.py: log_action() helper for audit logging
All models include proper foreign key relationships and PostgreSQL
enum types are managed correctly in migrations (create/drop).
