truth status reason artifacts missing
Attempting to access document content via an admin JWT returns 403 partial The documents API (backend/api/documents.py) has no authentication enforcement at all — no get_current_user dependency, no JWT validation. Any request (with or without a JWT) accesses documents. An admin JWT does not receive a 403; it is simply ignored. Admin.py has no document-content endpoints (SEC-07's admin-response clause is met), but the documents API does not reject admin-role tokens or any tokens.
path issue
backend/api/documents.py No auth dependency on any endpoint. get_current_user is not imported or used. This is the pre-Phase-3 single-user API state — per D-03 note in STATE.md, auth enforcement on documents is deferred to Phase 3.
Either: add get_current_user + role check to documents.py endpoints NOW to make admin-JWT return 403, OR explicitly scope SC5's 'admin JWT returns 403' clause as a Phase 3 deliverable in ROADMAP.md.

Phase 2: Users & Authentication — Verification Report

Phase Goal: Users can register, log in (with optional TOTP 2FA), reset their password, and sign out all active sessions; admins can manage user accounts and assign AI providers — all enforced by a complete FastAPI dependency chain.

Goal Achievement

Observable Truths (Success Criteria)

# Truth Status Evidence
SC1 New user can register with strength-validated password; HIBP-listed password rejected VERIFIED check_hibp() in services/auth.py uses k-anonymity SHA-1 prefix (5 chars); _validate_password_strength() enforces 12+ chars, upper, lower, digit, special; 4 tests covering register success, duplicate email, weak password, HIBP breach all pass
SC2 User can enroll TOTP authenticator, receive 10 backup codes with acknowledgment gate, TOTP required on every subsequent login, backup code invalidated on first use VERIFIED provision_totp(), generate_backup_codes(10), store_backup_codes() in services/auth.py; BackupCodesDisplay.vue has acknowledgment checkbox gating "Enable 2FA" button; verify_backup_code() iterates all codes (constant-time) and sets used_at=now() on match; Redis replay prevention on totp_used:{user_id}:{code} TTL=90s
SC3 User can reset password via email link (1-hour token), no auto-login after reset, returns to TOTP gate VERIFIED create_password_reset_token() / decode_password_reset_token() uses typ="password-reset" claim; /password-reset/confirm explicitly does NOT return access_token (comment: "AUTH-05 — user must pass TOTP gate on next login"); anti-enumeration: /password-reset always returns 202; test test_password_reset_confirm_valid_no_autologin passes
SC4 User can trigger "sign out all devices"; other sessions immediately invalidated; reuse of rotated refresh token revokes entire family VERIFIED revoke_all_refresh_tokens() marks all user's tokens revoked; rotate_refresh_token() checks row.revoked=True → calls revoke_all_refresh_tokens() + send_security_alert_email.delay() + raises ValueError("token_family_revoked"); logout_all endpoint (lines 370-379 api/auth.py) calls revoke_all_refresh_tokens()
SC5 Admin can create/deactivate/reset user accounts and assign AI provider; attempting to access document content via admin JWT returns 403 PARTIAL — BLOCKER Admin CRUD endpoints verified (7 endpoints, get_current_admin on all, _user_to_dict() whitelist excludes password_hash/credentials_enc). BUT: backend/api/documents.py has NO auth enforcement at all — any request (with or without JWT) accesses documents. An admin JWT is not rejected; it is simply ignored. The 403 clause of SC5 is not met.

Score: 4/5 truths verified


Gap Detail: SC5 — Admin JWT Document Access

Status: PARTIAL / BLOCKER

The documents API (backend/api/documents.py) has no get_current_user or get_current_admin dependency on any endpoint. No JWT is validated. This is the pre-Phase 3 single-user API state, explicitly noted in STATE.md (D-03 decision):

"documents.user_id nullable Phase 1 — D-03 — no auth in Phase 1; Phase 2 migration adds NOT NULL after auth lands"

However, SEC-07 (Phase 2 requirement) states: "Admin role verified on every admin endpoint request; admin cannot access document content, extracted text, or cloud credentials in any response." The admin API endpoints correctly meet the first clause (all protected by get_current_admin) and the second clause (no document content in admin responses via _user_to_dict() whitelist). But the documents API itself is fully open — an admin JWT does not return 403 when accessing document content there.

Phase 3's scope (Document Migration & Multi-User Isolation) will add get_current_user to document endpoints and enforce resource.user_id == current_user.id. Once Phase 3 lands, all users (including admins) will only see their own documents. However, the ROADMAP SC5 specifically says "admin JWT returns 403 for document content" as a Phase 2 deliverable.

Options for resolution:

  1. Add a narrow role-check guard in documents.py now (e.g., admin role in get_current_user → 403) — minimal Phase 2 work
  2. Update ROADMAP.md to scope the "admin JWT → 403 on documents" clause to Phase 3 alongside full auth enforcement
  3. Accept as-is noting Phase 3 fully resolves it (with ROADMAP update)

Human Verification Required

4 items need human testing:

1. TOTP Enrollment End-to-End

Test: Log in as a user, navigate to Account settings, click "Set up two-factor authentication", scan the otpauth:// link with an authenticator app, enter the 6-digit code, view the 10 backup codes screen, check the acknowledgment checkbox, click "Enable 2FA"

Expected: 2FA is enabled; next logout + login requires a TOTP code or backup code; login succeeds with valid code and fails with invalid code

Why human: Multi-step flow requires a real authenticator app; the otpauth:// link rendering (note: QR image is not rendered — only the link text) is a known MVP deviation

2. Password Reset Email Delivery

Test: Trigger password reset for a test account; check the email inbox; follow the reset link; set a new password; attempt to log in without TOTP

Expected: Email arrives with correct reset link; link expires after 1 hour; successful reset returns "Password updated. Please sign in." message (no tokens); login proceeds to TOTP gate if 2FA was enabled

Why human: Requires SMTP server (Celery + email infrastructure) and actual email receipt; anti-enumeration means the 202 response alone can't confirm email dispatch

3. Sign Out All Devices

Test: Log in from two browser tabs; click "Sign out all devices" in Account settings in Tab 1; make an authenticated request in Tab 2

Expected: Tab 2's access token is invalidated on next request; Tab 2 is redirected to login; reusing the revoked refresh token causes full family revocation

Why human: Multi-session testing requires two live sessions; refresh token reuse detection requires timing

4. Admin Panel Role Visibility

Test: Log in as a regular user; verify Admin link is NOT visible in sidebar. Log in as admin; verify "Admin" link with shield icon appears; navigate Users / Quotas / AI Config tabs; create a test user; deactivate them; reset their password

Expected: Non-admin users never see the admin UI; admin can perform all CRUD operations; inline deactivation confirmation shows correct user email

Why human: Visual rendering and role-conditional DOM requires browser; inline confirmation UX requires human interaction


Gaps Summary

1 BLOCKER gap preventing full Phase 2 goal achievement:

SC5 — Admin JWT → 403 on document content

The documents API (backend/api/documents.py) is completely unauthenticated — a Phase 1 legacy state explicitly noted in STATE.md (D-03 decision). An admin JWT does NOT return 403 when accessing document endpoints because the documents API has no JWT validation at all. The admin.py API correctly has no document content endpoints, and _user_to_dict() correctly excludes sensitive fields. But the literal clause of SC5 and SEC-07's "admin cannot access document content...in any response" is not enforced at the document endpoint layer.

Root cause: Phase 2 scope defines auth enforcement on new endpoints (api/auth.py, api/admin.py) but does not retrofit authentication onto the legacy api/documents.py, api/topics.py, or api/settings.py. Phase 3 ("Document Migration & Multi-User Isolation") will add per-user isolation to these endpoints.

Recommended resolution before marking Phase 2 complete:

  • Narrowest fix: add a current_user: User = Depends(get_current_user) check to document endpoint functions, returning 403 if user.role == "admin" — minimal change, no migration needed
  • Broader fix: update ROADMAP.md to scope SC5's "admin JWT → 403 on documents" clause as part of Phase 3 auth enforcement (where get_current_user will be added everywhere anyway)
