- Service `app/services/test_templates.py`: CRUD with MITRE tag resolution (kind, external_id) → polymorphic join, filters by tactic/technique/ subtechnique/opsec/tag, `_UNSET` sentinel for partial-update semantics. - Service `app/services/scenario_templates.py`: ordered test list, reorder via full-replace (atomic w.r.t. UNIQUE(position) constraint), soft-delete. - REST endpoints on /api/v1/test-templates and /scenario-templates with pydantic schemas + perm gating (test_template.* and scenario_template.*). - /diag/reset truncates the 4 new tables before MITRE (FK ordering). - 19 pytest covering CRUD, MITRE tag merge, soft-delete chaining, perm enforcement, and reorder atomicity.
