- backend/tests/test_mitre.py: 12 integration tests using a hand-crafted minimal STIX bundle (no network in tests). Covers parser (revoked/deprecated skip, sub-technique parent linkage), seed idempotence, persisted settings, checksum mismatch path, all four read endpoints, perm enforcement on /mitre/sync, ILIKE search. - e2e/tests/m4-mitre.spec.ts: 6 Playwright tests against the live stack. beforeAll calls POST /mitre/sync once (real bundle, ~50 MB, ~1.1 s) then the suite validates tactics ≥14, T1003 has ≥5 sub-techniques, the picker walks tactic→technique→subtechnique with chip multi-select, and non-admin sees /mitre but no Sync card. - tasks/testing-m4.md: manual + automated checklist, air-gapped operator notes, volume-permission caveat for pre-existing root-owned volumes.
