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.
