T-109: Rewrite tests router with full Red/Blue workflow endpoints - list with filters, create from template, Red/Blue team updates with state guards, start-execution, submit-red, submit-blue, validate-red, validate-blue, reopen, and timeline. All using workflow service from Phase 11.
T-110: Rewrite evidence router with Red/Blue separation - upload with team field, list with team filter, delete with state-based permissions. Red Team edits in draft/red_executing, Blue Team in blue_evaluating, admin bypasses all.
T-111: Create test_templates router with full CRUD - paginated list with source/platform/severity/search filters, by-technique lookup, admin-only create/update, and soft delete. Registered in main.py.
T-112: Add POST /system/import-atomic-tests endpoint to system router - admin-only trigger for Atomic Red Team import with error handling and statistics response.
Includes validation tests for all four tasks (35 checks total).
T-106: Create test_workflow_service.py with state-machine transitions for the complete test lifecycle (draft -> red_executing -> blue_evaluating -> in_review -> validated/rejected), dual validation by Red/Blue leads, and reopen capability with field cleanup.
T-107: Update status_service.py to use detection_result from Blue Team instead of legacy result field, and differentiate between partial progress (some validated) vs all-in-progress states.
T-108: Create atomic_import_service.py that downloads the Atomic Red Team repo as a ZIP (avoiding API rate limits), parses all atomics YAML files, and creates idempotent TestTemplate records mapped to MITRE techniques.
Includes validation tests for all three tasks (19 checks total).
- Add Pydantic schemas for Technique, Test and Evidence
- Add CRUD endpoints for Techniques (list with filters, detail, create, update, review)
- Add CRUD endpoints for Tests (create, detail, update, validate, reject)
- Add evidence upload with SHA-256 integrity and presigned download URLs
- Add MinIO/S3 storage client with bucket auto-creation on startup
- Add status_service to recalculate technique coverage from test results
- Add require_any_role RBAC dependency for multi-role authorization
- Update README with API endpoints reference and project structure
