  "summary": "Iteration 7 — Backend-only test of Super Admin Control Panel (admin_panel.py + auth.py 2FA flow). Built /app/backend/tests/test_admin_panel.py (20 pytest cases) — 20/20 PASSED (100%) after fixing one ObjectId-in-response bug in POST /api/admin/announcements. Verified: GET /api/admin/dashboard returns full KPI shape (users/license/devices/logins.trend_24h[24]/business) and 403s for non-admin (cashier). 2FA full lifecycle: status→setup-start (secret + base64 PNG QR) → setup-confirm with wrong code → 400, with valid pyotp TOTP → enabled + 10 recovery codes. Full 2FA login challenge flow verified end-to-end: fresh login returns requires_2fa=true + challenge_token (no cookies set, /me still 401); /api/auth/2fa/verify with wrong code → 401, with valid TOTP → sets access_token+refresh_token httpOnly cookies and returns user object (/me works after). 2FA disable: no code → 422, valid code → disabled. User control: reset-password (force_change persisted, new pw works on login), temp-password returns 12-char letters+digits (force_change=true), toggle-active twice flips false→true (deactivated user gets 403 on login), self-toggle returns 409, revoke-sessions kills existing JWT (401 on subsequent /me), force-change flips flag, /users/{uid}/activity returns audit rows. Feature flags: GET returns 15 flags (matches DEFAULT_FEATURES), PUT ai_assistant=false persists & GET reflects, unknown key → 404. Maintenance: GET/PUT roundtrip works, /api/maintenance/public (no auth) reflects state. Announcements CRUD + /announcements/active filter by audience works. Audit: failed login writes auth.login.failed row, success writes auth.login.success row, filter by action+email works. Settings: read returns DEFAULT_SETTINGS shape (min_password_length=8, session_timeout_minutes=720), PUT with values below floor (6) and above ceiling (64) clamps correctly to bounds. Pre-existing regression: 107/109 non-admin tests pass (2 staff-login failures pre-existed — staff@rmregal.com is auto-purged by cleanup_demo_users on startup, unrelated to admin panel).",

    "auth.py get_current_user(): comparison `iat < invalid_before` mixes ISO-string ordering with timezone-aware iso strings.

The 2 staff-login failures in test_backend.py are pre-existing (staff@rmregal.com auto-purged on startup) and NOT caused by admin_panel changes — they were failing before this iteration too.

  "rca of the issue": "POST /api/admin/announcements returned 500. RCA: in admin_panel.py create_announcement(), `await db.announcements.insert_one(doc)` mutates the input dict adding `_id: ObjectId(...)`. The return statement then spread the mutated dict: `return {'ok': True, 'id': str(r.inserted_id), **doc}` — leaking the raw ObjectId into the response. FastAPI's jsonable_encoder cannot encode ObjectId (tries dict(obj) and vars(obj), both fail) → ValueError → 500. Reproduction: any POST /api/admin/announcements call. Mitigation: build the response from a filtered dict excluding `_id`. Fix applied + verified by pytest. Same pattern should be audited across the codebase wherever insert_one(doc) is followed by a spread of `doc` into a response — `list_announcements`, `list_audit`, and `user_activity` already correctly pop/rename _id."
