Adds the mission layer that materialises template snapshots, plus the SPA
list / 3-step wizard / detail page.
Backend:
- app/services/missions.py — create_mission snapshots scenarios, tests, MITRE
tags in a 4-query write; list/get apply a non-admin membership filter that
collapses to 404 (no existence leak); status state machine enforces
draft → in_progress → completed → archived with archived as a sink; the
non-admin creator is auto-added as role_hint='red' to retain visibility.
- app/api/missions.py — 8 endpoints (list, get, create, update, add
scenarios, set members, transition, soft-delete) with strict pydantic
schemas. The transition endpoint splits the perm gate manually so
archive requires mission.archive while other targets use mission.update.
- app/api/users.py — new GET /users/roster returning (id, email,
display_name) only, gated by user.read OR mission.create OR
mission.update — lets non-admin wizard users see assignable peers
without exposing the admin /users payload.
- app/api/diag.py — /diag/reset truncates the mission_* tables before the
template tables because the source_*_template_id FKs are ON DELETE SET
NULL, which is cheaper to short-circuit by removing the children first.
Frontend:
- lib/missions.ts — typed client, queryKey factory, status accent map.
- pages/MissionsListPage.tsx — list cards with status accent + filters
(q, client, status).
- pages/MissionsCreatePage.tsx — 3-step wizard (meta → scenarios → members)
with member roster fed by /users/roster.
- pages/MissionDetailPage.tsx — header + transition buttons (legal next
states only) + Tests/Members/Synthesis/Export tabs.
- Routes + nav entry (visible to anyone with mission.read or admin).
Tests:
- backend/tests/test_missions.py — 22 pytest covering snapshot fidelity,
MITRE propagation, membership visibility, transition state machine,
perm gating, member set replace, append scenarios, soft-delete, partial
update, inverted-date rejection.
- e2e/tests/m6-missions.spec.ts — 5 Playwright (snapshot freezing, non-admin
visibility, status transitions + 409, SPA wizard end-to-end, list filter).
Docs:
- CHANGELOG, tasks/testing-m6.md, tasks/lessons.md (snapshot tradeoffs,
membership=404 pattern, /diag/reset order, auto-creator add).
- README + tasks/todo.md updated.

- lib/mitre.ts: shared types (MitreTactic, Technique, Subtechnique, MitreTag
kind/id/external_id/name) + TanStack query keys.
- components/MitreTagPicker.tsx: three-column controlled picker (tactic →
technique → subtechnique), multi-select with chip-removal, autocomplete on
each column, ARIA labels for screen readers. Returns MitreTag[] via
value/onChange — drop-in for M5 template forms.
- pages/MitrePage.tsx: status card (version, source URL, last_sync), admin-
gated Trigger Sync button with success/error alerts, picker showcase, JSON
preview of the current selection.
- Layout adds MITRE nav link for any logged-in user; App.tsx adds the
/mitre route under RequireAuth. HomePage roadmap bumped to next: M5
templates.
