# Phase 2: Users & Authentication — Verification Report (Re-Verification after Plan 06 Gap Closure)

**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.

**Verified:** 2026-06-01T14:35:00Z
**Status:** HUMAN NEEDED (all automated checks pass; 5 items require human testing; 2 security invariants from CLAUDE.md require developer resolution)
**Re-verification:** Yes — after Plan 06 gap closure (5 UAT gaps closed)

## Goal Achievement

### Observable Truths (Success Criteria from Plan 06 must_haves)

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| T1 | Admin can create a new user via POST /api/admin/users without HTTP 500 | VERIFIED | `await session.flush()` at admin.py:247 (before `write_audit_log()`); `test_create_user_writes_audit_log` passes (1 passed, 2.23s) |
| T2 | Login, register, and password-reset pages show AuthLayout only — no sidebar, no user identity footer | VERIFIED | App.vue line 2: `<AuthLayout v-if="route.meta.layout === 'auth'" />`; all 4 auth routes have `meta: { public: true, layout: 'auth' }` in router/index.js (4 grep matches at lines 22, 27, 32, 37) |
| T3 | After logout the sidebar is gone — the user lands on the login page with AuthLayout | VERIFIED | Same App.vue v-if fix covers logged-out state; /login has `layout: 'auth'` meta so AuthLayout renders, not app shell |
| T4 | Non-admin user navigating to /admin is redirected to / | VERIFIED | router/index.js:91-93: `if (to.meta.requiresAdmin && authStore.user?.role !== 'admin') return { path: '/' }`; /admin has `meta: { requiresAdmin: true }` at line 42 |
| T5 | TOTP enrollment step 1 shows a scannable QR image, not a text link | VERIFIED | TotpEnrollment.vue:111 `import QRCode from 'qrcode'`; line 120 `const qrDataUrl = ref('')`; line 136 `qrDataUrl.value = await QRCode.toDataURL(qrUri.value, ...)`; line 34 `<img v-if="qrDataUrl" :src="qrDataUrl" alt="TOTP QR code" ...>` |
| T6 | TOTP enrollment option is accessible from a tab within /settings (Account tab) | VERIFIED | SettingsView.vue:92 imports SettingsAccountTab; line 100 `{ id: 'account', label: 'Account' }` in tabs array; line 52 `<SettingsAccountTab v-if="activeTab === 'account'" />`; SettingsAccountTab.vue contains TotpEnrollment component at line 63 |

### Deferred Items (from Initial Verification — SC5)

Items not yet met but explicitly addressed in later milestone phases.

| # | Item | Addressed In | Evidence |
|---|------|-------------|---------|
| 1 | Attempting to access document content via an admin JWT returns 403 | Phase 3 | Phase 3 goal: "Document Migration and Multi-User Isolation." CONTEXT.md D-07: `/api/documents`, `/api/topics`, `/api/settings` stay public in Phase 2; gain `get_current_user` guards in Phase 3. REQUIREMENTS.md: SEC-04 mapped to Phase 3. The admin panel API (`/api/admin/*`) correctly enforces `get_current_admin` on all endpoints. |

### Open Code Review Findings (from 02-REVIEW.md)

These findings were surfaced by the code reviewer after plan 06 execution and are NOT yet fixed. They represent security invariants and UX gaps that require developer attention before Phase 2 can be considered fully resolved.

#### CR-01 — BLOCKER: Password change does not revoke active sessions

**File:** `backend/api/auth.py` line 520 (`change_password` endpoint)
**Issue:** CLAUDE.md line 153 requires: "Password change, TOTP enroll/revoke, and account deactivation immediately revoke all active sessions." The `change_password` handler updates `password_hash` and commits but does not call `revoke_all_refresh_tokens()`. An attacker with a previously-stolen refresh cookie retains full access for up to 30 days after the victim changes their password.
**Fix required:** Add `await auth_service.revoke_all_refresh_tokens(session, current_user.id)` after `session.commit()` in the `change_password` handler. Also redirect the current session to /login in the frontend `changePassword()` success path.

#### CR-02 — BLOCKER: TOTP disable does not revoke active sessions

**File:** `backend/api/auth.py` line 641 (`disable_totp` endpoint)
**Issue:** Same CLAUDE.md line 153 requirement. The `disable_totp` handler clears `totp_secret`, sets `totp_enabled=False`, and deletes backup codes but does not revoke any refresh tokens. An attacker can downgrade account security and both the attacker and any stolen sessions remain valid.
**Fix required:** Add `await session.execute(delete(RefreshToken).where(RefreshToken.user_id == current_user.id))` + `await session.commit()` in the `disable_totp` handler after backup code deletion.

#### CR-03 — WARNING: Dead `#confirm-button` slot in SettingsAccountTab removes spinner/guard on sign-out-all

**File:** `frontend/src/components/settings/SettingsAccountTab.vue` lines 149–161
**Issue:** `ConfirmBlock.vue` defines no named slot. The `<template #confirm-button>` block is silently ignored by Vue; the custom button with `:disabled="signingOutAll"` and `<AppSpinner>` never renders. Double-invocation of `signOutAll()` is possible with no spinner feedback.
**Fix required:** Either add `<slot name="confirm-button">` fallback in `ConfirmBlock.vue`, or guard with `if (signingOutAll.value) return` at the top of `signOutAll()`.

#### WR-01 — WARNING: URIError crash path in SettingsView.vue onMounted

**File:** `frontend/src/views/SettingsView.vue` — `decodeURIComponent(errorMsg)` in onMounted
**Issue:** No try/catch. Malformed `cloud_error` query param (e.g. lone `%`) throws URIError; user sees blank cloud tab with no error message.
**Fix required:** Wrap in try/catch, fall back to raw `errorMsg` value.

#### WR-02 — WARNING: TOTP verify code button re-enables during 800ms success flash

**File:** `frontend/src/components/auth/TotpEnrollment.vue`
**Issue:** `loading` is cleared in `finally` before the 800ms timeout fires; `verifyCode` not cleared on success. Button re-enables, allowing duplicate `api.totpEnable()` call. Backend replay prevention should reject it but UX is broken.
**Fix required:** Clear `verifyCode.value = ''` immediately after `api.totpEnable()` succeeds.

#### WR-03 — WARNING: Fragile string-matching for password error routing

**File:** `frontend/src/components/settings/SettingsAccountTab.vue`
**Issue:** `passwordError.includes('Current')` routes errors to field-level vs. form-level display. Unexpected API messages containing "Current" will be misrouted.
**Fix required:** Use separate refs for field-level and form-level errors.

#### WR-04 — WARNING: `topicsStore.fetchTopics()` fires on auth page loads

**File:** `frontend/src/App.vue` line 20
**Issue:** `onMounted(() => topicsStore.fetchTopics())` runs on every route including /login, /register, /password-reset. The backend returns 401; the API client attempts a token refresh (which fails); auth store clears its already-null accessToken. Spurious 401 + failed refresh on every auth page load.
**Fix required:** Guard the call behind `authStore.accessToken` check, or move it to the authenticated app shell.

#### IN-01 — INFO: qrcode uses caret range instead of exact pin

**File:** `frontend/package.json`
**Issue:** `"qrcode": "^1.5.4"` — CLAUDE.md requires exact version pinning for security-critical packages.
**Fix recommended:** Pin to `"qrcode": "1.5.4"`.

### Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| `backend/api/auth.py` | 520 | `change_password` commits without `revoke_all_refresh_tokens()` | BLOCKER | Active sessions survive password change — CLAUDE.md line 153 security invariant violated |
| `backend/api/auth.py` | 641 | `disable_totp` commits without `revoke_all_refresh_tokens()` | BLOCKER | Active sessions survive TOTP disable — CLAUDE.md line 153 security invariant violated |
| `frontend/src/components/settings/SettingsAccountTab.vue` | 149–161 | `<template #confirm-button>` renders into nonexistent slot — dead code | WARNING | Spinner and double-click guard never activate on sign-out-all |
| `frontend/src/App.vue` | 20 | `topicsStore.fetchTopics()` unconditional on mount | WARNING | Spurious 401 + failed token refresh on every auth page load |
| `frontend/src/views/SettingsView.vue` | onMounted | `decodeURIComponent()` without try/catch | WARNING | URIError crash on malformed cloud_error query param |
| `frontend/src/components/auth/TotpEnrollment.vue` | verify step | `verifyCode` not cleared on success before 800ms timeout | WARNING | Button re-enables during flash window — double-submission possible |

No TBD/FIXME/XXX markers found in Phase 2 plan-06 deliverable files.

### Human Verification Required

**5 items need human testing:**

#### 1. TOTP Enrollment End-to-End

**Test:** Log in as a user, navigate to /settings, click the Account tab. Find the "Two-factor authentication" section. Click to set up 2FA. Verify a scannable QR image (not a text link) appears. Scan the QR with an authenticator app (Google Authenticator, Authy, etc.). Enter the 6-digit code. Verify the backup codes screen shows 10 codes in a 2-column grid with a Copy All button and acknowledgment checkbox. Check the acknowledgment box. Click Enable 2FA. Confirm account shows 2FA active. Log out and log back in — confirm TOTP step is required.

**Expected:** QR image renders (no `<a href="otpauth://...">` link visible). 10 backup codes displayed. Acknowledgment checkbox gates Enable 2FA button. After enabling: login requires TOTP code or backup code.

**Why human:** Multi-step flow requires a real authenticator app; QR image rendering requires visual confirmation; the backup-code gate requires UI interaction.

#### 2. Password Reset Email Delivery

**Test:** Navigate to /password-reset. Enter a valid email address. Verify the page always shows a generic "check your email" message (no enumeration of valid/invalid email). Check the inbox. Follow the reset link. Set a new strong password. Verify no auto-login after reset. Navigate to /login and log in with the new password. Confirm TOTP gate appears if 2FA was enabled.

**Expected:** Email arrives with correct signed link. Link expires after 1 hour. Successful reset shows "Password updated. Please sign in." with no tokens issued. TOTP gate on next login if enrolled.

**Why human:** Requires SMTP infrastructure running and actual email receipt. Anti-enumeration means the 202 response alone cannot confirm email dispatch.

#### 3. Sign Out All Devices

**Test:** Log in from two browser tabs or browsers. In Tab 1, go to /settings > Account tab > Sessions. Click "Sign out all devices." Verify a ConfirmBlock appears. On confirm: Tab 1 redirects to /login. In Tab 2, make an authenticated request (e.g., navigate or refresh). Verify Tab 2 is redirected to /login.

**Expected:** Both tabs lose access after "sign out all devices." Reusing a revoked refresh token causes family revocation.

**Why human:** Multi-session behavior requires two live sessions; refresh token reuse detection requires timing across requests.

#### 4. Admin Panel Role Visibility and CRUD

**Test:** Log in as a regular user. Verify the Admin link is NOT visible in the sidebar. Navigate to /admin directly. Verify redirect to /. Log in as admin. Verify "Admin" link with shield icon appears in sidebar. Navigate to /admin. Test: (a) Users tab — list all users; (b) Create a new test user — verify HTTP 200/201 and the user appears in the table (no HTTP 500); (c) Deactivate the test user — verify inline confirmation shows correct email; (d) Quotas tab — view/adjust a quota; (e) AI Config tab — change a provider and verify save flash.

**Expected:** Non-admin users blocked from /admin (redirected to /). Admin CRUD operations work. No HTTP 500 on user creation.

**Why human:** Visual rendering, role-conditional DOM, and inline confirmation UX require browser interaction.

#### 5. CR-01/CR-02: Session Revocation on Password Change and TOTP Disable (EXPECTED FAIL until fix applied)

**Test:** In Browser 1, log in. In Browser 2, log in as the same user. In Browser 1: change the password (Settings > Account tab). In Browser 2: attempt any authenticated action (e.g., navigate to /settings). Verify Browser 2 is redirected to /login. Repeat: In Browser 1, disable TOTP (if enrolled). In Browser 2: verify session is invalidated.

**Expected:** Both Browser 2 sessions are invalidated immediately after password change or TOTP disable in Browser 1.

**Why human:** Requires confirming backend revocation with live sessions. NOTE: This test is expected to FAIL in the current codebase. CR-01 and CR-02 are confirmed open — neither `change_password` nor `disable_totp` in `backend/api/auth.py` calls `revoke_all_refresh_tokens()`. This is a CLAUDE.md line 153 security invariant violation. A fix plan is required before Phase 2 can be marked fully complete.

---

## Gaps Summary

**0 automated gaps blocking phase goal.** All 6 plan-06 must-have truths are VERIFIED. The SC5 gap from the initial verification (admin JWT on documents) is deferred to Phase 3 per D-07 and has been removed from blocking status.

**2 SECURITY BLOCKERS from code review (CR-01, CR-02)** — these are CLAUDE.md security invariant violations requiring a fix plan:

- **CR-01:** `change_password` does not revoke active sessions (backend/api/auth.py:520)
- **CR-02:** `disable_totp` does not revoke active sessions (backend/api/auth.py:641)

These are not UAT-detectable bugs — they are security architecture violations. A gap-closure plan is required targeting only these two backend endpoints. The fixes are each 3–5 lines (call `revoke_all_refresh_tokens()` after commit). The frontend should also redirect to /login after a successful password change.

**4 WARNINGS from code review (WR-01 through WR-04)** — lower priority UX and robustness issues not blocking the phase goal but recommended for resolution before Phase 3 begins.
