+<objective>
+Add a new admin overview backend endpoint at `GET /api/admin/overview` that returns aggregated platform stats (user count, total storage, document status breakdown) plus the 10 most recent audit-log entries in a single response payload, and register it on the admin parent router. Backed by `backend/tests/test_admin_overview.py` covering ADMIN-11 + security invariants.
+
+Purpose: ADMIN-11 requires an admin overview that combines stats + recent audit entries; D-02 mandates a new `overview.py` sub-module inside `backend/api/admin/`; D-03 requires the audit rows inline (single HTTP call, no `/api/audit` round-trip from the overview view).
+
+Output: `backend/api/admin/overview.py` (new), `backend/api/admin/__init__.py` (modified — one import + one include_router call), `backend/tests/test_admin_overview.py` (new — 3 promoted tests).

+  - `_audit_to_dict_with_handles(audit_log_row, owner_handle, target_user_handle, ip)` — returns a safe dict for one audit entry; the security-audited whitelist serializer reused for ADMIN-06.
+
+From backend/db/models.py:
+  - `User` (fields used: `id`, `role` literal `'user'` vs `'admin'`)
+  - `Quota` (fields used: `used_bytes`)
+  - `Document` (fields used: `status`)
+  - `AuditLog`
+
+From backend/deps/auth.py:
+  - `get_current_admin` — FastAPI dependency that raises 401 (no token) or 403 (non-admin token).
+
+From backend/api/admin/__init__.py (current state):
+  - `router = APIRouter(prefix="/api/admin", tags=["admin"])` — parent aggregator; sub-routers MUST carry NO prefix per the "NO prefix" WHY comment at the top of the file (do not remove that comment in this plan).

+# Phase 09 Plan 01: Admin Overview Endpoint Summary
+
+**One-liner:** New `GET /api/admin/overview` endpoint returning aggregated user count, total storage bytes, per-status document breakdown, and last 10 audit entries in a single admin-protected payload.
+
+## Tasks Completed
+
+| # | Task | Commit | Status |
+|---|------|--------|--------|
+| 1 | Create Wave 0 xfail test stubs (TDD RED) | `4caeed2` | Done |
+| 2 | Implement overview.py + register on admin router (TDD GREEN) | `41d81c0` | Done |
+
+## Files Created
+
+- `backend/api/admin/overview.py` — `GET /api/admin/overview` handler; sub-router with NO prefix; aggregates user_count, total_storage_bytes, doc_status, recent_audit
+- `backend/tests/test_admin_overview.py` — 8 tests covering auth guards, aggregate correctness, and sensitive-field scan
+
+## Files Modified
+
+- `backend/api/admin/__init__.py` — added `overview_router` import and `include_router(overview_router)` call
+
+## Test Results
+
+- `pytest tests/test_admin_overview.py` — 8 passed, 0 failed, 0 xfailed
+- `pytest tests/test_admin_api.py tests/test_audit.py` — 34 passed, 0 failed (no regressions)
+- Total: 42 passed, 0 failed
+
+## Security Invariants Verified
+
+- `GET /api/admin/overview` guarded by `get_current_admin` (raises 401/403)
+- Response is a hand-rolled dict with exact keys: `user_count`, `total_storage_bytes`, `doc_status`, `recent_audit`
+- Audit entries serialized via `_audit_to_dict_with_handles` whitelist — same security-audited helper used by the audit log viewer
+- `test_overview_no_sensitive_fields` scans `resp.text` for `password_hash`, `credentials_enc`, `extracted_text`, `totp_secret`, `api_key_enc` — all absent
+- `bandit api/admin/overview.py` — zero HIGH findings
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+None — plan executed exactly as written, with one minor adjustment:
+
+**[Rule 2 - Minor] Import split for acceptance criteria compliance**
+- The plan's acceptance criteria checks `grep -c "from api.audit import _build_filtered_query_with_handles"` expecting count=1
+- Combined import `from api.audit import _build_filtered_query_with_handles, _audit_to_dict_with_handles` would return 0 for that exact pattern
+- Split into two separate import lines to satisfy the grep check; functionally equivalent
+
+## Known Stubs
+
+None — all four aggregate fields return live DB query results.
+
+## Threat Flags
+
+None — the new endpoint is within the trust boundary documented in the plan's threat model (T-09-01-01, T-09-01-02, T-09-01-03 all mitigated as designed).
+
+## Self-Check: PASSED

+<objective>
+Create the admin route shell — `AdminLayout.vue` (the route component at `/admin`), `AdminSidebar.vue` (the admin-only sidebar with five nav links per D-07 and no Back-to-app per D-06), and `AdminOverviewView.vue` (the new overview view at `/admin` showing stats cards + last-10 audit table per D-01, D-03). Extend the frontend `api/admin.js` module with `getAdminOverview()` so the view can fetch the new backend endpoint.
+
+Purpose: ADMIN-08 requires `AdminLayout.vue` as the `/admin` route component with its own sidebar; ADMIN-09 defines the nav set (D-06 overrides the Back-to-app link); ADMIN-11 requires the overview UI. This plan builds the shell + new view; routing is wired in 09-04.
+
+Output: 4 new/modified frontend files. The shell renders correctly when manually mounted; the overview view single-fetches the backend endpoint built in 09-01.

+
+<interfaces>
+From frontend/src/api/client.js (re-export barrel from Phase 8):
+  - `request(path, options)` — the canonical fetch helper with 401-refresh handling. New API helpers MUST call `request()` and not roll their own `fetch`. Import via `./utils.js` in the domain module: `import { request } from './utils.js'`.
+
+From frontend/src/api/admin.js (existing domain module — Phase 8 CODE-04 output):
+  - Already exports `listAdminUsers`, `createAdminUser`, `setAdminUserQuota`, `getAiConfig`, etc. via `request()`. Add `getAdminOverview` alongside these.
+
+From frontend/src/stores/auth.js:
+  - `useAuthStore()` exposes `user` (ref with `{ email, role, ... }`) and `logout()` action. AdminSidebar imports the store for the user footer + sign-out.
+
+From frontend/src/components/layout/AppSidebar.vue (reference pattern):
+  - Container: `<aside class="w-64 bg-white border-r border-gray-200 flex flex-col h-full shrink-0">`
+  - Logo block: `<div class="px-6 py-5 border-b border-gray-100"><h1 class="text-lg font-bold text-indigo-600 tracking-tight">DocuVault</h1><p class="text-xs text-gray-400 mt-0.5">Document Manager</p></div>`
+  - Nav: `<nav class="flex-1 px-3 py-4 overflow-y-auto">…</nav>`
+  - Scoped CSS: `.nav-link { @apply flex items-center px-3 py-2 rounded-lg text-gray-600 hover:bg-gray-100 hover:text-gray-900 transition-colors text-sm font-medium; }` and `.nav-link-active { @apply bg-indigo-50 text-indigo-700; }`
+  - SVG attrs: `class="w-4 h-4 mr-2 shrink-0" fill="none" stroke="currentColor" viewBox="0 0 24 24"` with `stroke-linecap="round" stroke-linejoin="round" stroke-width="2"`
+  - User footer block exists at the bottom with avatar initial + email + sign-out button.
+
+From frontend/src/layouts/AuthLayout.vue (reference pattern):
+  - Simple template-only layout shell hosting `<router-view />`. AdminLayout follows the same "layout-as-route-component" pattern; App.vue requires NO changes.

+# Phase 09 Plan 02: Admin Route Shell — Layout, Sidebar, Overview View Summary
+
+**One-liner:** AdminLayout (flex sidebar shell), AdminSidebar (5 nav links, indigo Admin badge, no Back-to-app), AdminOverviewView (4-card stats + 10-row audit table fetching GET /api/admin/overview).
+
+## Tasks Completed
+
+| Task | Name | Commit | Files |
+|------|------|--------|-------|
+| 1 | Add getAdminOverview() to api/admin.js | fd12ee2 | frontend/src/api/admin.js |
+| 2 | Create AdminLayout.vue + AdminSidebar.vue | 4eb489f | frontend/src/layouts/AdminLayout.vue, frontend/src/components/admin/AdminSidebar.vue |
+| 3 | Create AdminOverviewView.vue | 1e14e15 | frontend/src/views/admin/AdminOverviewView.vue |
+
+## What Was Built
+
+### Task 1 — getAdminOverview()
+
+Added `export async function getAdminOverview()` to `frontend/src/api/admin.js`. The function calls `request('/api/admin/overview')` using the pre-existing `request` import from `utils.js`. No new import added. The function is automatically re-exported by `client.js` via the barrel export pattern established in Phase 8 CODE-04.
+
+### Task 2 — AdminLayout.vue + AdminSidebar.vue
+
+`AdminLayout.vue` is a minimal flex-row shell: `<div class="flex h-screen overflow-hidden">` wrapping `<AdminSidebar />` and a `<main>` with the content padding wrapper (`p-8 max-w-5xl mx-auto`) that contains `<router-view />`. Uses `<script setup>` importing `AdminSidebar` only.
+
+`AdminSidebar.vue` mirrors `AppSidebar.vue`'s chrome exactly:
+- `<aside class="w-64 bg-white border-r border-gray-200 flex flex-col h-full shrink-0">`
+- Logo header with `DocuVault` h1 and `Admin` subtitle in `text-xs text-indigo-500 font-semibold` (D-05)
+- 5 `<router-link>` elements in D-07 order with SVG icons (Overview, Users, Quotas, AI Config, Audit Log)
+- Overview uses `$route.path === '/admin'` exact match; the four children use `startsWith('/admin/<segment>')`
+- User identity footer + sign-out (copied verbatim from AppSidebar.vue)
+- Scoped CSS: `.nav-link` and `.nav-link-active` with identical `@apply` rules to AppSidebar.vue
+- No Back-to-app link (D-06 applied)
+
+### Task 3 — AdminOverviewView.vue
+
+Single-fetch view with local `ref` state (no Pinia store). `onMounted` calls `getAdminOverview()` with loading/error handling. Template structure:
+- `<h2>Overview</h2>` heading
+- Loading and error states
+- `<template v-else-if="overview">` containing:
+  - 4-column stat cards grid (`grid grid-cols-1 md:grid-cols-4 gap-4`) with Users, Storage, Processing, Ready cards
+  - Recent audit table (`<table>`) with columns: When / Event / Actor / Target / IP
+  - "No recent activity" placeholder when `recent_audit` is empty
+
+## Key Decisions
+
+### 4-Card Choice Rationale
+
+ADMIN-11 lists exactly 4 stats: total users, total storage, and document status breakdown (processing/ready). D-01 says "3-4 stat cards". 4 was chosen because:
+1. The backend `doc_status` field naturally provides two metrics (processing + ready) — splitting them into two cards makes the breakdown visible without extra clicks
+2. A 4-column grid fills the `max-w-5xl` content area proportionally
+
+### No Top-Level Padding in AdminOverviewView
+
+`AdminLayout.vue` owns `p-8 max-w-5xl mx-auto`. Per Pitfall 9 (RESEARCH.md), adding padding inside the view would double the padding. The view's root `<div>` has no padding classes.
+
+### No Back-to-App Link
+
+D-06 overrides ADMIN-09: admin accounts are operators only. The sidebar has exactly 5 destination links. No `/` router-link exists anywhere in `AdminSidebar.vue`.
+
+## Deviations from Plan
+
+None — plan executed exactly as written.
+
+## Threat Flags
+
+None — no new network endpoints, auth paths, or trust boundaries beyond the plan's threat model.

+---
+
+<objective>
+Promote the four existing admin tab components (`AdminUsersTab.vue`, `AdminQuotasTab.vue`, `AdminAiConfigTab.vue`, `AuditLogTab.vue`) into standalone view files in `frontend/src/views/admin/` (D-11). Extraction is **structural and behavior-preserving** — same template, same script, same data fetches, same emitted actions, with import paths rewritten for the new location and the component renamed in the script setup.
+
+Purpose: D-11 mandates the tab components become views. D-13 mandates AuditLog is promoted as-is (no new features). The Phase 9 architecture (D-09/D-10/D-11) requires each admin section be a standalone deep-linkable view component — `AdminLayout`'s `<router-view />` must render them.
+
+Output: 4 new view files. Original tab components and `AdminView.vue` are deleted in 09-04 (after router rewiring). This plan does NOT delete anything and does NOT touch the router — those land in 09-04 to keep the codebase in a buildable state between waves.

+From RESEARCH.md §Pattern 4 (codebase audit):
+  - `AdminUsersTab.vue` — top element `<div>`, no padding.
+  - `AdminQuotasTab.vue` — top element `<div>`, no padding.
+  - `AdminAiConfigTab.vue` — top element `<div>`, no padding.
+  - `AuditLogTab.vue` — top element `<div>`, no padding.
+
+Tab components currently live at depth `frontend/src/components/admin/` (two levels deep from `src/`). Extracted views live at `frontend/src/views/admin/` (also two levels deep). Therefore relative imports of the form `../../api/...`, `../../stores/...`, `../../utils/...` resolve identically from the new location — **no relative import paths need adjustment**. Any imports that go through `../layout/...` (one level up to `components/`) would break, but these tab components do NOT import any sibling component under `components/`.
+
+Verify before extracting each file: `grep -E "^import" frontend/src/components/admin/<TabFile>.vue` — every import path should already start with `../../` (relative to `components/admin/`). If any import uses a different depth, document the rewrite in the SUMMARY.

If neither convention is used, no rename is needed. Verify every import line resolves from the new path (use the rule in `<interfaces>`: `../../<segment>` resolves identically). If `AdminUsersTab.vue` declares props that were used to receive data from `AdminView.vue` and they are no longer relevant (e.g. a `currentUser` prop), remove the `defineProps` block AND audit where those props were referenced — if a prop was only used as a passthrough, replace its template references with direct store reads (`useAuthStore().user`). Do NOT change template DOM, do NOT change `onMounted` fetches, do NOT change emitted events (emitted events are dropped at the view boundary — they no longer have a parent listening; check whether any emit was the sole trigger of a fetch on the parent — if so, replace the emit with a direct re-fetch inside the view).

+# Phase 09 Plan 03: Tab-to-View Extraction Summary
+
+**One-liner:** Four admin tab components promoted verbatim to standalone view files under `frontend/src/views/admin/` with one import path rewrite (SearchableModelSelect) and no behavioral changes.
+
+## Tasks Completed
+
+| Task | Name | Commit | Files |
+|------|------|--------|-------|
+| 1 | Extract AdminUsersView + AdminQuotasView | `d690a44` | frontend/src/views/admin/AdminUsersView.vue, frontend/src/views/admin/AdminQuotasView.vue |
+| 2 | Extract AdminAiView + AdminAuditView | `164003b` | frontend/src/views/admin/AdminAiView.vue, frontend/src/views/admin/AdminAuditView.vue |
+
+## What Was Built
+
+### Task 1 — AdminUsersView.vue + AdminQuotasView.vue
+
+**AdminUsersView.vue** is a verbatim copy of `AdminUsersTab.vue` (480 lines → 480 lines). No props removed (source had none). No emit calls removed (source had none). Import paths `../../utils/formatters.js` and `../../api/client.js` resolve identically from `views/admin/` as from `components/admin/`. Root `<div>` has no padding classes.
+
+**AdminQuotasView.vue** is a verbatim copy of `AdminQuotasTab.vue` (182 lines → 182 lines). Same import path analysis — `../../api/client.js` resolves identically. Root `<div>` has no padding classes.
+
+### Task 2 — AdminAiView.vue + AdminAuditView.vue
+
+**AdminAiView.vue** is a copy of `AdminAiConfigTab.vue` (391 lines → 391 lines) with one import path rewrite:
+
+- Before (from `components/admin/`): `import SearchableModelSelect from '../ui/SearchableModelSelect.vue'`
+- After (from `views/admin/`): `import SearchableModelSelect from '../../components/ui/SearchableModelSelect.vue'`
+
+The System AI Providers (Global) section is preserved above the per-user assignment table per the Phase 7 cross-cutting constraint. All other imports (`../../api/client.js`) resolve unchanged.
+
+**AdminAuditView.vue** is a verbatim copy of `AuditLogTab.vue` (346 lines → 346 lines) per D-13 (promote as-is). The `actionTypeClass()` helper is preserved verbatim with all dynamic color classes (`bg-blue-50 text-blue-600`, `bg-purple-50 text-purple-600`, `bg-amber-50 text-amber-700`, `bg-gray-100 text-gray-600`) intact for Tailwind safelist coverage in 09-04.
+
+## Dead Prop Removals
+
+None. Reading `AdminView.vue` confirmed that all four tab components were mounted with no prop-passing:
+
+```html
+<AdminUsersTab v-if="activeTab === 'users'" />
+<AdminQuotasTab v-if="activeTab === 'quotas'" />
+<AdminAiConfigTab v-if="activeTab === 'ai'" />
+<AuditLogTab v-if="activeTab === 'audit'" />
+```
+
+No `defineProps` blocks existed in any source component, so no prop removal was needed.
+
+## Orphaned Emit Replacements
+
+None. No source tab component contained any `emit()` calls. All data fetches are self-contained in `onMounted()` handlers within each view.
+
+## Verification Results
+
+- `npm run build` (worktree): 143 modules transformed, 0 errors — PASSED
+- All 4 new view files exist under `frontend/src/views/admin/` — PASSED
+- Root `<div>` has no padding classes on any view — PASSED
+- `grep -c "actionTypeClass" AdminAuditView.vue` returns 2 — PASSED
+- `grep -c "bg-amber-50" AdminAuditView.vue` returns 1 — PASSED
+- `grep -c "bg-purple-50" AdminAuditView.vue` returns 1 — PASSED
+- `grep -c "System AI" AdminAiView.vue` returns 2 — PASSED
+- Original tab components in `frontend/src/components/admin/` untouched — PASSED
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**[Rule 3 - Import Path Rewrite] SearchableModelSelect path adjusted for new directory depth**
+
+- **Found during:** Task 2 (import analysis before extraction)
+- **Issue:** `AdminAiConfigTab.vue` imports `SearchableModelSelect` via `'../ui/SearchableModelSelect.vue'` (relative to `components/admin/`). From `views/admin/`, this path resolves to `views/ui/` which does not exist.
+- **Fix:** Rewrote to `'../../components/ui/SearchableModelSelect.vue'` — the absolute path is the same; only the relative traversal changed due to the directory depth shift.
+- **Files modified:** `frontend/src/views/admin/AdminAiView.vue`
+
+The plan's `<interfaces>` section explicitly documented this rule: "Verify before extracting each file: `grep -E "^import"` — every import path should already start with `../../`." The `../ui/` path was the one exception, caught by the pre-extraction audit.
+
+## Known Stubs
+
+None — these are structural promotions of existing components. No data is hardcoded or mocked. All fetch logic calls the real API.
+
+## Threat Flags
+
+None — no new network endpoints, auth paths, file access patterns, or schema changes introduced. The extraction is purely structural; trust boundaries are unchanged from the plan's threat model (T-09-03-01, T-09-03-02 both mitigated as designed).

+<objective>
+Wire the router to use `AdminLayout.vue` as the `/admin` route component with five lazy-loaded children (one per admin view). Fix the `beforeEach` guard so it uses `to.matched.some(r => r.meta.requiresAdmin)` and apply D-09/D-10 strict admin role separation. Wire the login-success handler so admin users land at `/admin` and regular users at `/`. Add the Tailwind safelist (D-14 corrected to include `sky` and `amber`). Delete `AdminView.vue` and the four `AdminXxxTab.vue` files (D-12).
+
+Purpose: ADMIN-08 (AdminLayout becomes the route component), ADMIN-10 (deep-linkable URLs), ADMIN-12 (`to.matched.some()` guard), CODE-06 (safelist), and the cleanup mandate from D-12 (delete dead `AdminView.vue` + four tab files).
+
+Output: rewired router, fixed guard, login redirect, Tailwind safelist, and a clean repo with zero references to the deleted files.

+<interfaces>
+From CONTEXT.md and RESEARCH.md (locked):
+  - D-08: admin login → `/admin`.
+  - D-09: admin on non-admin route → redirect `/admin`.
+  - D-10: non-admin on `/admin/*` → redirect `/`. Both checks use `to.matched.some(r => r.meta.requiresAdmin)`.
+  - D-14 (corrected by RESEARCH.md Pattern 7): safelist must include `sky` (formatters.js OneDrive) and `amber` (AuditLogTab `actionTypeClass()`):
+    ```
+    safelist: [
+      { pattern: /bg-(blue|sky|green|purple|orange|amber|gray|indigo|red)-(50|100|500|600)/ },
+      { pattern: /text-(blue|sky|green|purple|orange|amber|gray|indigo|red)-(400|500|600|700)/ },
+    ]
+    ```
+
+From RESEARCH.md Pattern 3 (LoginView.vue current code):
+  - `handleLoginResult(result)` — when `!result`, currently `const redirect = route.query.redirect || '/'; await router.push(redirect)`. Modify the `!result` branch only.
+
+From frontend/src/stores/auth.js (verified RESEARCH.md):
+  - `user.value = data.user` runs synchronously inside the `login()` action before it returns — so `authStore.user.role` is populated when `handleLoginResult(!result)` fires.
+
+From PATTERNS.md (current router state):
+  - `frontend/src/router/index.js` currently has `{ path: '/admin', component: () => import('../views/AdminView.vue'), meta: { requiresAdmin: true } }` as a flat route.
+  - Existing guard is `if (to.meta.requiresAdmin && authStore.user?.role !== 'admin') { return { path: '/' } }` — the broken check that lets child routes through.
+  - Auth-only routes (`/login`, `/register`, etc.) carry `meta: { public: true, layout: 'auth' }` — both flags MUST be preserved unchanged.
+  - Other user routes (`/`, `/topics`, `/folders/:id`, `/shared`, `/account`, `/settings`, `/cloud/...`) have no `requiresAdmin` flag and no `public` flag → these are the routes that the D-09 admin-redirect MUST send admins away from.

+  <name>Task 1: Rewire router/index.js — nested /admin + corrected guard + Tailwind safelist</name>
+  <files>frontend/src/router/index.js, frontend/tailwind.config.js</files>
+  <read_first>
+    - frontend/src/router/index.js (full current file — locate the existing flat `/admin` route and the existing `beforeEach` guard for in-place replacement)
+    - frontend/tailwind.config.js (current 9-line config — add a `safelist:` array between `content:` and `theme:`)
+    - frontend/src/utils/formatters.js (confirm the dynamic class set; the safelist must cover every family referenced here)
+    - frontend/src/components/admin/AuditLogTab.vue (confirm `actionTypeClass()` uses `bg-amber-50 text-amber-700` plus blue/gray/purple families)
+  </read_first>
+  <behavior>
+    - The router replaces the existing flat `/admin` route with a nested route whose `component` is the lazy-loaded `AdminLayout.vue` and whose `children` are five lazy-loaded admin views in the order: `''` (Overview), `users`, `quotas`, `ai`, `audit`. Each lazy import uses `() => import('../views/admin/Admin<Name>View.vue')`.
+    - The parent `/admin` route carries `meta: { requiresAdmin: true }`. Child routes do NOT individually re-declare `requiresAdmin` — the guard relies on `to.matched.some()` to inherit from the parent.
+    - The `beforeEach` guard:
+      1. If route is non-public and `authStore.accessToken` is null, attempt silent refresh; on failure redirect to `/login?redirect=<original>`.
+      2. Compute `isAdminRoute = to.matched.some(r => r.meta.requiresAdmin)`.
+      3. Compute `isAdmin = authStore.user?.role === 'admin'`.
+      4. D-10a: if `isAdminRoute && !isAdmin` → redirect `{ path: '/' }`.
+      5. D-09: if `!isAdminRoute && !to.meta.public && isAdmin` → redirect `{ path: '/admin' }`.
+    - Auth-public routes (`/login`, `/register`, `/forgot-password`, `/reset-password`) remain reachable for both admin and non-admin users (the `!to.meta.public` clause exempts them).
+    - The Tailwind config gains a `safelist` array with two regex patterns covering `bg-(blue|sky|green|purple|orange|amber|gray|indigo|red)-(50|100|500|600)` and `text-(blue|sky|green|purple|orange|amber|gray|indigo|red)-(400|500|600|700)`.
+  </behavior>
+  <action>Open `frontend/src/router/index.js`. Locate the existing flat `/admin` route and replace it with the nested structure: parent `path: '/admin'`, `component: () => import('../layouts/AdminLayout.vue')`, `meta: { requiresAdmin: true }`, and a `children: [...]` array of five entries — `{ path: '', component: () => import('../views/admin/AdminOverviewView.vue') }`, then `{ path: 'users', component: () => import('../views/admin/AdminUsersView.vue') }`, then `quotas` → `AdminQuotasView.vue`, then `ai` → `AdminAiView.vue`, then `audit` → `AdminAuditView.vue`. Remove the old `() => import('../views/AdminView.vue')` reference entirely (Task 3 deletes that file). Replace the current `beforeEach` guard body with the 5-step structure from `<behavior>`: refresh-then-guard, computing `isAdminRoute` via `to.matched.some(r => r.meta.requiresAdmin)`, then the two D-09 / D-10a redirect branches. Preserve the existing public-route bypass: every route currently bearing `meta: { public: true }` (login, register, password reset) must still resolve without the admin/non-admin checks firing — the `!to.meta.public` clauses in steps 4 and 5 ensure this. Do NOT remove `meta.layout: 'auth'` from any auth route — `App.vue` still reads it. Open `frontend/tailwind.config.js`. Add a `safelist:` property between the existing `content:` line and the `theme:` block. The array contains two objects with `pattern` regexes exactly as specified in `<interfaces>`. Do NOT alter the existing `content`, `theme`, or `plugins` lines.</action>

+## What Was Built
+
+### Task 1 — Nested /admin Route + Guard + Tailwind Safelist
+
+**Router rewire:** The flat `/admin` route pointing to the deleted `AdminView.vue` is replaced with a nested route whose `component` is the lazy-loaded `AdminLayout.vue`. Five children are registered:
+
+```
+{ path: '',       AdminOverviewView.vue }   → /admin
+{ path: 'users',  AdminUsersView.vue }      → /admin/users
+{ path: 'quotas', AdminQuotasView.vue }     → /admin/quotas
+{ path: 'ai',     AdminAiView.vue }         → /admin/ai
+{ path: 'audit',  AdminAuditView.vue }      → /admin/audit
+```
+
+Only the parent carries `meta: { requiresAdmin: true }`. Child routes intentionally do not repeat it — the guard uses `to.matched.some(r => r.meta.requiresAdmin)` which walks the full matched ancestors array, making the parent's meta apply to every child.
+
+**Guard fix:** The old `if (to.meta.requiresAdmin && ...)` check is replaced with a 5-step guard:
+1. Silent refresh on non-public routes with no access token
+2. Compute `isAdminRoute = to.matched.some(r => r.meta.requiresAdmin)`
+3. Compute `isAdmin = authStore.user?.role === 'admin'`
+4. D-10a: `isAdminRoute && !isAdmin` → redirect `{ path: '/' }`
+5. D-09: `!isAdminRoute && !to.meta.public && isAdmin` → redirect `{ path: '/admin' }`
+
+The `!to.meta.public` clause in step 5 ensures auth routes (`/login`, `/register`, `/password-reset`, `/password-reset/confirm`) remain reachable for admin users — this is the critical escape hatch that prevents redirect loops when an admin session expires and the guard sends them to `/login`.
+
+**Tailwind safelist:** Two regex patterns added covering all dynamic class families:
+- `bg-(blue|sky|green|purple|orange|amber|gray|indigo|red)-(50|100|500|600)` — covers `providerBg()` (OneDrive=sky, Google Drive=blue, Nextcloud=orange, WebDAV=gray) and `actionTypeClass()` (auth=blue, folder/share=purple, admin=amber, document=gray)
+- `text-(blue|sky|green|purple|orange|amber|gray|indigo|red)-(400|500|600|700)` — covers `providerColor()` and `actionTypeClass()` text variants
+
+`sky` and `amber` were the two families missing from the original D-14 draft. RESEARCH.md Pattern 7 (confirmed in CONTEXT.md) corrects this — both are included.
+
+### Task 2 — Admin Login Redirect (D-08)
+
+The `handleLoginResult(!result)` branch in `LoginView.vue` is updated:
+
+```js
+const defaultRedirect = authStore.user?.role === 'admin' ? '/admin' : '/'
+const redirect = route.query.redirect || defaultRedirect
+await router.push(redirect)
+```
+
+`authStore.user.role` is synchronously populated inside `authStore.login()` before the store action returns (verified by reading `auth.js` line 82: `user.value = data.user`), so the role check fires with a fully populated user object.
+
+The `?redirect=` query param is still honored for non-admin users. For admin users, the D-09 guard in the router would intercept any `?redirect=/` attempt and redirect back to `/admin` anyway — the D-08 check here is belt-and-suspenders.
+
+The `requires_totp` and `requires_password_change` branches are byte-for-byte unchanged.
+
+### Task 3 — Delete Legacy Files + Migrate Tests
+
+**Five files deleted via `git rm`:**
+- `frontend/src/views/AdminView.vue` — old tab-container view, replaced by `AdminLayout` + nested routes
+- `frontend/src/components/admin/AdminUsersTab.vue` — promoted to `views/admin/AdminUsersView.vue` in 09-03
+- `frontend/src/components/admin/AdminQuotasTab.vue` — promoted to `views/admin/AdminQuotasView.vue` in 09-03
+- `frontend/src/components/admin/AdminAiConfigTab.vue` — promoted to `views/admin/AdminAiView.vue` in 09-03
+- `frontend/src/components/admin/AuditLogTab.vue` — promoted to `views/admin/AdminAuditView.vue` in 09-03
+
+**Test migrations** (import path rewrite only — no test logic changed):
+- `__tests__/AdminUsersTab.test.js`: `import AdminUsersTab from '../AdminUsersTab.vue'` → `from '../../../views/admin/AdminUsersView.vue'`
+- `__tests__/AdminQuotasTab.test.js`: `import AdminQuotasTab from '../AdminQuotasTab.vue'` → `from '../../../views/admin/AdminQuotasView.vue'`
+- `__tests__/AdminAiConfigTab.test.js`: `import AdminAiConfigTab from '../AdminAiConfigTab.vue'` → `from '../../../views/admin/AdminAiView.vue'`
+
+**Router guard test updated:**
+- Replaced `vi.mock('../../views/AdminView.vue', ...)` with mocks for `layouts/AdminLayout.vue` and all five `views/admin/Admin*View.vue` files
+- Added D-09 redirect test: admin navigating to `/` is redirected to `/admin`
+
+**Two stale comments updated (Rule 2 — correctness):**
+- `src/api/admin.js` JSDoc consumer list updated from `AdminXxxTab.vue` names to `Admin*View.vue` names
+- `src/views/SettingsView.vue` stale `<!-- Tab strip (copy AdminView pattern verbatim) -->` comment simplified to `<!-- Tab strip -->`

+
+## Smoke Check (Build Artifacts)
+
+`npm run build` produced separate lazy-loaded chunks for all 5 admin routes:
+- `AdminLayout-BbuVmUU8.js` (4.46 kB) — AdminLayout entry chunk
+- `admin-BFKH-0jn.js` (3.04 kB) — shared admin chunk
+- `AdminOverviewView-DUqzmtNA.js` (3.49 kB)
+- `AdminQuotasView-Cao0PSry.js` (4.53 kB)
+- `AdminAuditView-DDh7qqQi.js` (9.24 kB)
+- `AdminUsersView-BLLys8CV.js` (12.62 kB)
+- `AdminAiView-CZ8yB8IZ.js` (16.43 kB)
+
+`AdminAuditView` chunk contains the full `actionTypeClass()` logic with `bg-amber-50 text-amber-700` and `bg-blue-50 text-blue-600` classes — confirmed present in build output. Tailwind safelist ensures these survive tree-shaking in production.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**[Rule 2 - Missing Critical Functionality] Added D-09 redirect test to router guard test**
+
+- **Found during:** Task 3 (router guard test update)
+- **Issue:** The test file verified the non-admin → `/` redirect (D-10a) but had no test for the admin → `/admin` redirect (D-09). D-09 is a security-relevant guard branch — omitting it from the test suite is a missing correctness invariant.
+- **Fix:** Added `it('redirects an admin user away from / to /admin (D-09)', ...)` test with admin role mock navigating to `/` and asserting `router.currentRoute.value.path === '/admin'`.
+- **Files modified:** `frontend/src/router/__tests__/router.guard.test.js`
+- **Commit:** `e6467d1`
+
+**[Rule 1 - Bug] Stale JSDoc consumer list in api/admin.js**
+
+- **Found during:** Task 3 (grep scan for stale references)
+- **Issue:** `src/api/admin.js` JSDoc listed the deleted `AdminXxxTab.vue` and `AuditLogTab.vue` names as consumers. Post-deletion, these filenames no longer exist — an inaccurate comment is a correctness issue.
+- **Fix:** Updated JSDoc consumer list to `AdminUsersView.vue, AdminQuotasView.vue, AdminAiView.vue, AdminAuditView.vue`.
+- **Files modified:** `frontend/src/api/admin.js`
+- **Commit:** `e6467d1`
+
+**[Rule 1 - Bug] Stale AdminView reference in SettingsView.vue comment**
+
+- **Found during:** Task 3 (grep scan for `AdminView` references)
+- **Issue:** `src/views/SettingsView.vue` contained `<!-- Tab strip (copy AdminView pattern verbatim) -->`. After `AdminView.vue` is deleted, this comment references a non-existent file.
+- **Fix:** Simplified to `<!-- Tab strip -->`.
+- **Files modified:** `frontend/src/views/SettingsView.vue`
+- **Commit:** `e6467d1`
+
+**[Rule 3 - Blocking] npm not installed in worktree frontend — installed deps locally**
+
+- **Found during:** Task 1 verification (npm run build)
+- **Issue:** The worktree's `frontend/` directory had no `node_modules/`. `npm run build` failed with `ERR_MODULE_NOT_FOUND` for vite.
+- **Fix:** Ran `npm install` + `npm approve-scripts --allow-scripts-pending` in the worktree's `frontend/`. Build succeeded after this.
+- **Files modified:** None (dev-time infrastructure only — `node_modules/` is gitignored).
+
+## Known Stubs
+
+None — no hardcoded data or placeholder content introduced. All admin routes resolve to the real view components from 09-02 and 09-03.
+
+## Threat Flags
+
+None — no new network endpoints, API routes, or trust boundaries introduced. This plan is purely frontend routing and build configuration.
+
+Threat mitigations from the plan's threat register:
+- **T-09-04-01 (Elevation of Privilege):** `to.matched.some(r => r.meta.requiresAdmin)` guard covers all `/admin/*` child routes — IMPLEMENTED. Backend `get_current_admin` dependency remains the authoritative second gate.
+- **T-09-04-02 (Privilege Escalation via ?redirect=):** D-08 puts role check FIRST; even `?redirect=/` for an admin routes through the D-09 guard — IMPLEMENTED.
+- **T-09-04-03 (CSS purge of dynamic classes):** Tailwind safelist covers `sky` (OneDrive) and `amber` (audit admin badge) — IMPLEMENTED. Build output confirms separate admin chunks exist.
+- **T-09-04-04 (Redirect loop):** `isAdminRoute` for `/admin/*` short-circuits D-09 so admins on admin routes are not redirected; auth routes have `!to.meta.public` guard — IMPLEMENTED.
+
+## Self-Check: PASSED
+
+- `frontend/src/router/index.js` — MODIFIED (nested /admin + corrected guard)
+- `frontend/tailwind.config.js` — MODIFIED (safelist added)
+- `frontend/src/views/auth/LoginView.vue` — MODIFIED (admin login redirect)
+- `frontend/src/views/AdminView.vue` — DELETED

+- Commit `e6467d1` (Task 3) — FOUND
+- `npm run build` succeeds (0 errors, 5 admin chunks in output) — PASSED
+- `npm test` — 137/137 tests passed — PASSED
+- No stale `AdminView` / `AdminXxxTab` imports remain — PASSED

+
+<objective>
+Apply the CODE-09 comment purge across (a) every file touched in Phase 9 (both backend and frontend) and (b) retroactively across the Phase 8 backend sub-packages (`backend/api/admin/`, `backend/api/documents/`, `backend/api/auth/`). Remove every "what" comment (generic docstrings, "this does X" inline notes). Keep every "why" comment (constraints, pitfall notes, non-obvious invariants — D-16). The `prefix="/api/admin"` / "NO prefix" constraint comments are the canonical "why" exemplars and MUST be preserved.
+
+Purpose: CODE-09 requires that no comment describes WHAT code does. D-15 mandates a single dedicated plan at the end of Phase 9 covering Phase 9 files plus Phase 8 backend sub-packages.
+
+Output: cleaner code; same behavior; full test suite green; frontend build green.

+From D-16 (purge criterion):
+  - **REMOVE** comments that describe WHAT the code does: generic function docstrings like `"""Return all users."""`, inline `# Loop over users` notes, `// Set state to loading` annotations, comment blocks restating the obvious from the next line.
+  - **KEEP** comments that explain WHY: constraint notes (e.g., "NO prefix — parent carries /api/admin"), pitfall references (e.g., "T-08-04-04 prevention"), non-obvious invariants (e.g., "constant-time comparison required for token validation"), security boundary notes (e.g., "never include credentials_enc here").
+
+From RESEARCH.md §Pitfall 6 (explicit exemption):
+  - The constraint docstring at the top of `backend/api/admin/__init__.py` ("sub-routers carry NO prefix") reads like a docstring but is actually a non-obvious invariant comment. PRESERVE IT.
+  - Equivalent constraint comments at the top of `backend/api/auth/__init__.py` and `backend/api/documents/__init__.py` follow the same rule — if they document the prefix invariant or a cross-module import constraint, PRESERVE.
+
+From CLAUDE.md (Code Standards):
+  - "Comments exist only where the *why* is non-obvious. Never explain what the code does."
+
+Phase 8 backend file inventory (from RESEARCH.md Open Question 3 + repo audit):

+    Phase 9 is complete after this checkpoint. The user verifies that:
+    - The five admin URLs render the correct view with the admin sidebar.
+    - Login as admin lands at `/admin`; login as regular user lands at `/`.
+    - A non-admin navigating to `/admin/users` is bounced to `/`.
+    - An admin navigating to `/` is bounced to `/admin`.
+    - OneDrive provider chip renders in sky color in production build; audit action badges render in amber.
+    - Spot-checking three random purged files confirms that the surviving comments are all genuine WHY notes.
+  </what-built>
+  <how-to-verify>
+    1. Backend suite: `cd backend && pytest -v` — record passed count; must equal the 09-04 baseline.
+    2. Frontend build: `cd frontend && npm run build` — must succeed.
+    3. Start the stack: `docker compose up -d` (or `cd backend && uvicorn main:app --reload` + `cd frontend && npm run dev`).
+    4. As an **admin** user: log in. Confirm you land at `/admin`. Click each of the 5 nav links and confirm: Overview shows 4 stat cards + a 10-row recent-activity table; Users/Quotas/AI/Audit show their full pre-Phase-9 functionality.
+    5. Open browser dev tools, paste `/topics` into the URL bar. Confirm the guard redirects you back to `/admin`.
+    6. Log out. Log in as a **non-admin** user. Confirm you land at `/` (or `?redirect=` target).
+    7. Paste `/admin/users` into the URL bar. Confirm the guard redirects you to `/`.
+    8. Production build visual check: with `npm run build && npm run preview`, look at an account with OneDrive connected (or open the Cloud sidebar) — the OneDrive chip should render in sky color, NOT default gray. Open the audit log — the action-type badges should show their amber/blue/purple colors.
+    9. Open three random files from the Task 1 and Task 2 file lists (your pick). For each, scan the remaining comments: each comment must be a WHY note. If any comment merely restates the next line of code, the purge missed it — record the file + line in your feedback.
+  </how-to-verify>
+  <resume-signal>Type "approved" if all steps pass. Otherwise describe what failed (e.g., "OneDrive chip is gray in production build" or "/admin/audit 404s after admin login").</resume-signal>

+## Summary
+
+CODE-09 comment purge applied across all Phase 9 files and retroactively to Phase 8 backend sub-packages. WHAT comments (generic docstrings, inline labels, section headers) removed. WHY comments preserved per D-16: security invariants, non-obvious constraints, decision references (D-08/D-09/D-10/D-16/D-17), the api_key write-only invariant, and the NO-prefix anchor comments in all three __init__.py files.
+

+# Phase 9: Admin Panel Rearchitecture - Context
+
+**Gathered:** 2026-06-12
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+Phase 9 delivers: (1) `AdminLayout.vue` registered as the `/admin` route component with its own sidebar and `<router-view />`; (2) each admin section extracted as a deep-linkable child route (`/admin`, `/admin/users`, `/admin/quotas`, `/admin/ai`, `/admin/audit`); (3) a new admin overview page at `/admin` showing platform stats + last 10 audit entries; (4) the `requiresAdmin` guard updated to protect all `/admin/*` children; (5) strict admin role separation — admin accounts are redirected to `/admin` on all user routes; (6) Tailwind safelist configured for dynamic `providerColor`/`providerBg`/`providerLabel` class patterns; (7) `AdminView.vue` and the original `AdminXxxTab.vue` components deleted; (8) CODE-09 comment purge pass over all Phase 9 files and retroactively over Phase 8 backend sub-packages.
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Admin Overview Page (ADMIN-11)
+
+- **D-01:** Layout: 3–4 stat cards in a top row (total users, total storage, document status breakdown: processing/ready/failed), followed by a table of the last 10 audit log entries below.
+- **D-02:** Backend: new `overview.py` sub-module in `backend/api/admin/` alongside the existing `users.py`, `quotas.py`, `ai.py`. Single `GET /api/admin/overview` endpoint returning all four stats in one payload.
+- **D-03:** Audit entries are inline in the aggregate response — the overview call returns stats + last 10 entries in one HTTP request. No separate `/api/audit` call from the overview component.
+
+### Admin Sidebar Design (ADMIN-09 — PARTIAL OVERRIDE)
+
+- **D-04:** SVG icons for each sidebar nav item — consistent with `AppSidebar.vue` pattern.
+- **D-05:** Visual identity: subtle "Admin" label or badge below the DocuVault logo in the sidebar header. Same indigo brand color. No accent color change.
+- **D-06:** **No "Back to app" link.** Admin role is administration-only. If an admin user needs to use the document app, they must have a separate normal user account. This overrides the ADMIN-09 requirement text that specified "Back to app link at bottom returns to /".
+- **D-07:** Nav items (in order): Overview, Users, Quotas, AI Config, Audit Log. No "Back to app".
+
+### Admin Role Strict Separation (NEW — not in original requirements)
+
+- **D-08:** After login, if `user.role === 'admin'`, the router redirects to `/admin` instead of `/`.
+- **D-09:** The `beforeEach` guard detects admin role on non-admin routes and redirects to `/admin`. Admin accounts cannot navigate to user routes (`/`, `/topics`, `/settings`, `/cloud`, etc.).
+- **D-10:** Two guards in `beforeEach`: (a) non-admin attempting `/admin/*` → redirect to `/`; (b) admin attempting non-admin route → redirect to `/admin`. Both must use `to.matched.some(r => r.meta.requiresAdmin)` for the admin check (Vue Router 4 does not inherit meta to children).
+
+### Tab Component Extraction (ADMIN-08, ADMIN-10)
+
+- **D-11:** The four existing tab components (`AdminUsersTab.vue`, `AdminQuotasTab.vue`, `AdminAiConfigTab.vue`, `AuditLogTab.vue`) become standalone view files (`AdminUsersView.vue`, `AdminQuotasView.vue`, `AdminAiView.vue`, `AdminAuditView.vue`) in `frontend/src/views/admin/`. Extraction is structural only: strip top-level padding (owned by `AdminLayout`), rename, wire as router children.
+- **D-12:** Original `components/admin/AdminXxxTab.vue` files are deleted after extraction — they become dead code. `AdminView.vue` is deleted.
+- **D-13:** `AuditLogTab.vue` is promoted as-is. No new features, filters, or backend changes for the audit log view in Phase 9.
+
+### Tailwind Safelist (CODE-06)
+
+- **D-14:** Add `safelist` in `tailwind.config.js` covering `providerColor`, `providerBg`, `providerLabel` dynamic class patterns from `formatters.js`. Pattern from PITFALLS.md §14:
+  ```js
+  safelist: [
+    { pattern: /bg-(blue|green|purple|orange|gray|indigo|red)-(50|100|500|600)/ },
+    { pattern: /text-(blue|green|purple|orange|gray|indigo|red)-(500|600|700)/ },
+  ]
+  ```
+  Researcher verifies which color families `formatters.js` actually uses and adjusts the pattern if needed.
+
+### CODE-09 Comment Purge
+
+- **D-15:** One dedicated plan at the end of Phase 9 covers all files touched in Phase 9 plus retroactive purge of Phase 8 backend sub-packages (`api/admin/`, `api/documents/`, `api/auth/`).
+- **D-16:** Purge criterion: remove comments that describe WHAT code does (generic function docstrings, inline "this does X" comments). Keep comments that explain WHY: constraints, pitfall notes, non-obvious invariants (e.g., `api/admin/__init__.py`'s "sub-routers carry NO prefix" constraint stays; generic "Returns user list" docstrings go).
+
+### Claude's Discretion
+
+- Exact SVG icon choices for each admin sidebar nav item (researcher picks appropriate icons from the same icon family used in AppSidebar.vue)
+- Exact Python queries for the overview aggregate endpoint (researcher reads `db/models.py` and determines the most efficient async query pattern)
+- Naming of the new view files if `views/admin/` directory structure is adopted (researcher confirms directory convention)
+
+</decisions>
+
+<canonical_refs>
+## Canonical References
+
+**Downstream agents MUST read these before planning or implementing.**
+
+### Phase Goals and Requirements
+- `.planning/ROADMAP.md` §"Phase 9: Admin Panel Rearchitecture" — goal, implementation notes, success criteria, pitfall references
+- `.planning/REQUIREMENTS.md` §ADMIN-08, ADMIN-09, ADMIN-10, ADMIN-11, ADMIN-12, CODE-06, CODE-09 — formal requirement definitions
+- **Note:** ADMIN-09 "Back to app link" is overridden by D-06 and D-08 above. CONTEXT.md decisions take precedence.
+
+### Vue Router 4 Admin Architecture
+- `.planning/research/PITFALLS.md` §Pitfall 3 — `to.matched.some()` guard fix (security regression risk with flat `to.meta.requiresAdmin`)
+- `.planning/research/PITFALLS.md` §Pitfall 4 — AdminLayout as route component, not App.vue v-else-if branch (double-render risk)
+- `.planning/research/PITFALLS.md` §Pitfall 9 — double padding risk when extracting tab content into views with AdminLayout wrapper
+- `.planning/research/PITFALLS.md` §Pitfall 14 — Tailwind purge of dynamic class names; safelist pattern
+
+### Frontend Architecture
+- `.planning/codebase/ARCHITECTURE.md` — component responsibilities, router guard, layout resolution pattern
+- `frontend/src/App.vue` — current AuthLayout switch pattern (AdminLayout must NOT be added as a third branch here)
+- `frontend/src/layouts/AuthLayout.vue` — reference pattern for a standalone layout component with `<router-view />`
+- `frontend/src/router/index.js` — current guard and route structure being rearchitected
+- `CLAUDE.md` §"Frontend: shared module map" — `formatters.js` is the single source for `providerColor`/`providerBg`/`providerLabel`
+- `CLAUDE.md` §"Component architecture" — View → Smart → Presentational layering (admin views follow this)
+
+### Backend Architecture
+- `backend/api/admin/__init__.py` — existing admin package aggregator pattern; `overview.py` is added alongside existing sub-modules
+- `backend/api/admin/users.py`, `quotas.py`, `ai.py` — reference for sub-module structure (overview.py follows same pattern)
+- `backend/api/audit.py` — existing audit log implementation; overview endpoint reuses its query logic for last 10 entries
+- `backend/db/models.py` — ORM models for users, quotas, documents (needed for aggregate queries)
+- `CLAUDE.md` §"Key Architectural Rules" — admin endpoints never return document content or credentials_enc
+
+### Existing Admin Components
+- `frontend/src/views/AdminView.vue` — being deleted; contains current tab structure
+- `frontend/src/components/admin/AdminUsersTab.vue` — being promoted to view
+- `frontend/src/components/admin/AdminQuotasTab.vue` — being promoted to view
+- `frontend/src/components/admin/AdminAiConfigTab.vue` — being promoted to view
+- `frontend/src/components/admin/AuditLogTab.vue` — being promoted to view
+- `frontend/src/utils/formatters.js` — dynamic class names that need safelist coverage
+
+</canonical_refs>
+
+<code_context>
+## Existing Code Insights
+
+### Reusable Assets
+- `frontend/src/layouts/AuthLayout.vue` — exact pattern for a standalone layout: a plain `<template>` wrapper with `<router-view />` inside. `AdminLayout.vue` follows this same structure.
+- `frontend/src/components/layout/AppSidebar.vue` — reference for SVG icon style, nav-link classes (`nav-link`, `nav-link-active`), logo/header structure, and sidebar dimensions (`w-64 bg-white border-r`). Admin sidebar reuses these classes.
+- `backend/api/admin/__init__.py` — aggregator pattern: import sub-routers, register with parent. `overview.py` adds one more import line here.
+- `backend/api/audit.py` — already has the paginated audit log query; `overview.py` reuses its query logic (limit=10) rather than duplicating it.
+
+### Established Patterns
+- `AdminLayout.vue` is the `/admin` route's `component:` — NOT a branch in `App.vue`. `App.vue` renders whatever the router resolves; it doesn't need to know about AdminLayout.
+- `beforeEach` guard in `router/index.js` uses `to.matched.some(r => r.meta.requiresAdmin)` — the ONLY correct Vue Router 4 idiom for parent-meta inheritance on child routes. A plain `to.meta.requiresAdmin` check silently breaks for all child routes.
+- Sub-routers in `api/admin/` carry NO `prefix` on `APIRouter()` — the parent carries `prefix="/api/admin"`. This constraint applies to `overview.py`.
+- `api/admin/__init__.py` does ONLY router aggregation — no helpers, no models. `overview.py` houses the endpoint logic.
+
+### Integration Points
+- `frontend/src/router/index.js` — add `/admin` as a nested route with `AdminLayout` as component; add five children (`''`, `users`, `quotas`, `ai`, `audit`); update `beforeEach` guard with D-09/D-10 admin redirect logic; update login-redirect to send admin role to `/admin`.
+- `frontend/src/App.vue` — no changes needed (AdminLayout handles its own layout; App.vue only needs the existing AuthLayout branch).
+- `backend/api/admin/__init__.py` — add `from api.admin.overview import router as overview_router` and register it.
+- `backend/main.py` — no changes needed (admin router registration unchanged).
+- `frontend/src/stores/auth.js` — login action may need to check `user.role === 'admin'` and set redirect target to `/admin`.
+- `frontend/tailwind.config.js` — add `safelist` array covering dynamic color patterns.
+
+</code_context>
+
+<specifics>
+## Specific Ideas
+
+- Admin overview layout: cards + table, not a full dashboard. Keep it simple — it's an operator utility page.
+- Admin sidebar: "Admin" label/badge below "DocuVault" in header signals admin context without heavy visual changes.
+- Strict role separation is a product decision: admin accounts are platform operators, not users. This is philosophically consistent with the privacy-first admin model already established in v0.1 (admin cannot read user documents or credentials).
+- The overview endpoint returns everything in one payload — makes the AdminOverviewView.vue a single-fetch component with no coordination logic.

If the admin wants to use the app he/she needs a normal user account. So please just create the admin controls for the admin user and no user view for the admin user."
+
+**Notes:** Major product decision — admin role is administration-only. No "Back to app" link. Admin users are redirected to /admin if they attempt to access user routes. After login, admin role lands on /admin. This overrides ADMIN-09's "Back to app link" requirement.
+
+Confirmed strict separation: admin accounts cannot access user routes, redirected to /admin.

+## Pattern Assignments
+
+### `frontend/src/layouts/AdminLayout.vue` (layout, request-response)
+
+**Analog:** `frontend/src/layouts/AuthLayout.vue`
+
+**Complete analog** (lines 1–12):
+```vue
+<template>
+  <div class="min-h-screen bg-gray-50 flex items-center justify-center">
+    <div class="w-full max-w-sm">
+      <!-- Brand logo -->
+      <div class="text-center mb-6">
+        <h1 class="text-xl font-semibold text-indigo-600 tracking-tight">DocuVault</h1>
+      </div>
+      <!-- Auth card content -->
+      <router-view />
+    </div>
+  </div>
+</template>
+```
+
+**AdminLayout pattern to implement** (mirrors above structure, adapted for sidebar layout):
+```vue
+<template>
+  <div class="flex h-screen overflow-hidden">
+    <AdminSidebar />
+    <main class="flex-1 overflow-y-auto">
+      <div class="p-8 max-w-5xl mx-auto">
+        <router-view />
+      </div>
+    </main>
+  </div>
+</template>
+
+<script setup>
+import AdminSidebar from '../components/admin/AdminSidebar.vue'
+</script>
+```
+
+**Critical constraint:** `App.vue` already has `<router-view />` in its `v-else` branch. When `/admin` resolves, that router-view renders `AdminLayout`, and `AdminLayout`'s own `<router-view />` renders child views. Do NOT add a third `v-else-if` branch to `App.vue` — this causes double rendering (RESEARCH.md Pitfall 2).
+
+The padding `p-8 max-w-5xl mx-auto` moves from `AdminView.vue` line 2 to `AdminLayout.vue`'s content wrapper. The four tab components have no top-level padding, so double-padding risk does not apply here.
+
+---
+
+### `frontend/src/components/admin/AdminSidebar.vue` (component, request-response)
+
+**Analog:** `frontend/src/components/layout/AppSidebar.vue`
+
+**Container pattern** (lines 2–7):
+```vue
+<aside class="w-64 bg-white border-r border-gray-200 flex flex-col h-full shrink-0">
+  <!-- Logo -->
+  <div class="px-6 py-5 border-b border-gray-100">
+    <h1 class="text-lg font-bold text-indigo-600 tracking-tight">DocuVault</h1>
+    <p class="text-xs text-gray-400 mt-0.5">Document Manager</p>
+  </div>
+```
+
+**Admin badge adaptation** — replace the `text-gray-400` subtitle with:
+```vue
+<p class="text-xs text-indigo-500 font-semibold mt-0.5">Admin</p>
+```
+
+**Nav section pattern** (lines 10–14):
+```vue
+<nav class="flex-1 px-3 py-4 overflow-y-auto">
+  <router-link
+    to="/topics"
+    class="nav-link"
+    :class="{ 'nav-link-active': $route.path.startsWith('/topics') }"
+  >
+```
+
+**Admin nav links pattern** (adapt active-state check per route):
+```vue
+<router-link to="/admin" class="nav-link"
+  :class="{ 'nav-link-active': $route.path === '/admin' }">
+  <svg class="w-4 h-4 mr-2 shrink-0" fill="none" stroke="currentColor" viewBox="0 0 24 24">
+    <path stroke-linecap="round" stroke-linejoin="round" stroke-width="2" d="..." />
+  </svg>
+  Overview
+</router-link>
+```
+
+**SVG icon attributes** (lines 16–19 of AppSidebar.vue — exact attributes to copy):
+```
+fill="none"
+stroke="currentColor"
+viewBox="0 0 24 24"
+class="w-4 h-4 mr-2 shrink-0"
+stroke-linecap="round" stroke-linejoin="round" stroke-width="2"
+```
+
+**User identity footer** (lines 215–230):
+```vue
+<div v-if="authStore.user" class="flex items-center gap-3 px-4 py-3 border-t border-gray-100 mt-2 -mx-3">
+  <div class="bg-indigo-100 text-indigo-700 text-xs font-semibold rounded-full w-8 h-8 flex items-center justify-center shrink-0">
+    {{ authStore.user.email ? authStore.user.email[0].toUpperCase() : '?' }}
+  </div>
+  <span class="text-xs text-gray-600 truncate flex-1">{{ authStore.user.email }}</span>
+  <button @click="signOut" aria-label="Sign out" class="text-gray-400 hover:text-gray-600 transition-colors">
+    <svg class="w-4 h-4" fill="none" stroke="currentColor" viewBox="0 0 24 24">
+      <path stroke-linecap="round" stroke-linejoin="round" stroke-width="2"
+        d="M17 16l4-4m0 0l-4-4m4 4H7m6 4v1a3 3 0 01-3 3H6a3 3 0 01-3-3V7a3 3 0 013-3h4a3 3 0 013 3v1" />
+    </svg>
+  </button>
+</div>
+```
+
+**Sign-out function** (lines 284–287):
+```javascript
+async function signOut() {
+  await authStore.logout()
+  router.push('/login')
+}
+```
+
+**Scoped CSS** (lines 317–322):
+```vue
+<style scoped>
+.nav-link {
+  @apply flex items-center px-3 py-2 rounded-lg text-gray-600 hover:bg-gray-100 hover:text-gray-900 transition-colors text-sm font-medium;
+}
+.nav-link-active {
+  @apply bg-indigo-50 text-indigo-700;
+}
+</style>
+```
+
+**Script imports pattern** (lines 236–251):
+```javascript
+import { ref } from 'vue'
+import { useRouter } from 'vue-router'
+import { useAuthStore } from '../../stores/auth.js'
+
+const authStore = useAuthStore()
+const router = useRouter()
+
+async function signOut() {
+  await authStore.logout()
+  router.push('/login')
+}
+```
+
+**D-06 constraint:** No "Back to app" link. Do not add a `/` router-link anywhere in AdminSidebar.
+
+---
+
+### `frontend/src/views/admin/AdminOverviewView.vue` (view, request-response)
+
+**Analog:** `frontend/src/components/admin/AdminUsersTab.vue` (data-fetch-on-mount pattern)
+
+**Top-level template structure** (AdminUsersTab.vue line 2):
+```vue
+<template>
+  <div>
+    <!-- content — no padding here; AdminLayout owns p-8 max-w-5xl mx-auto -->
+```
+
+**Data fetch pattern** (AdminUsersTab.vue script — onMounted with local ref state, no store):
+```javascript
+import { ref, onMounted } from 'vue'
+import * as api from '../../api/client.js'
+
+const loading = ref(false)
+const error = ref(null)
+const overview = ref(null)
+
+onMounted(async () => {
+  loading.value = true
+  try {
+    overview.value = await api.getAdminOverview()
+  } catch (e) {
+    error.value = e.message || 'Failed to load overview'
+  } finally {
+    loading.value = false
+  }
+})
+```
+
+**No Pinia store** — single-fetch component consistent with all existing admin tab components (confirmed by RESEARCH.md open question 2 answer).
+
+**Response shape to expect** (from RESEARCH.md Pattern 6):
+```
+{ user_count, total_storage_bytes, doc_status: { processing, ready, failed }, recent_audit: [...] }
+```
+
+**Stat card pattern** (use same border/rounded/bg pattern as AdminUsersTab.vue's create-user panel, line 4):
+```vue
+<div class="bg-white border border-gray-200 rounded-xl p-6">
+  <!-- stat card content -->
+</div>
+```
+
+**Audit table headers pattern** (copy from AuditLogTab.vue table header pattern for `recent_audit` rows).
+
+---
+
+### `frontend/src/views/admin/AdminUsersView.vue` (view, CRUD)
+
+**Analog:** `frontend/src/components/admin/AdminUsersTab.vue` — this IS the source file, promoted to a view.
+
+**Extraction rule** (RESEARCH.md Pattern 4): The tab component's top element is `<div>` with no padding. Copy entire file content. Rename component name in `<script setup>` if present. Wire as router child — no structural changes needed.
+
+**Top element** (AdminUsersTab.vue line 2):
+```vue
+<template>
+  <div>
+```
+
+No `p-8` or `max-w` at top level — confirmed safe to promote as-is.
+
+---
+
+### `frontend/src/views/admin/AdminQuotasView.vue` (view, CRUD)
+
+**Analog:** `frontend/src/components/admin/AdminQuotasTab.vue` — same extraction rule as AdminUsersView.
+
+Top element is `<div>` with no padding — confirmed safe to promote as-is.
+
+---
+
+### `frontend/src/views/admin/AdminAiView.vue` (view, CRUD)
+
+**Analog:** `frontend/src/components/admin/AdminAiConfigTab.vue` — same extraction rule.
+
+Top element is `<div>` with no padding — confirmed safe to promote as-is.
+
+---
+
+### `frontend/src/views/admin/AdminAuditView.vue` (view, request-response)
+
+**Analog:** `frontend/src/components/admin/AuditLogTab.vue` — same extraction rule.
+
+**Top element** (AuditLogTab.vue line 2):
+```vue
+<template>
+  <div>
+    <!-- Filter bar -->
+    <div class="flex flex-wrap gap-3 mb-4 items-end">
+```
+
+No padding at top level — confirmed safe to promote as-is.
+
+**Dynamic color classes that need safelist** (AuditLogTab.vue `actionTypeClass()` function):
+```
+bg-blue-50 text-blue-600
+bg-gray-100 text-gray-600
+bg-purple-50 text-purple-600
+bg-amber-50 text-amber-700
+```
+
+These are constructed dynamically and MUST be in `tailwind.config.js` safelist.
+
+---
+
+### `frontend/src/router/index.js` (config, request-response)
+
+**Analog:** `frontend/src/router/index.js` (self — modify in place)
+
+**Current flat admin route** (line 42 — to be replaced):
+```javascript
+{ path: '/admin', component: () => import('../views/AdminView.vue'), meta: { requiresAdmin: true } },
+```
+
+**Replacement nested route structure** (RESEARCH.md Pattern 2):
+```javascript
+{
+  path: '/admin',
+  component: () => import('../layouts/AdminLayout.vue'),
+  meta: { requiresAdmin: true },
+  children: [
+    { path: '', component: () => import('../views/admin/AdminOverviewView.vue') },
+    { path: 'users', component: () => import('../views/admin/AdminUsersView.vue') },
+    { path: 'quotas', component: () => import('../views/admin/AdminQuotasView.vue') },
+    { path: 'ai', component: () => import('../views/admin/AdminAiView.vue') },
+    { path: 'audit', component: () => import('../views/admin/AdminAuditView.vue') },
+  ],
+},
+```
+
+All use lazy `() => import(...)` — consistent with existing auth view imports on lines 20–33.
+
+**Current broken guard** (lines 91–93 — to be replaced):
+```javascript
+if (to.meta.requiresAdmin && authStore.user?.role !== 'admin') {
+  return { path: '/' }
+}
+```
+
+**Replacement guard** (RESEARCH.md Pattern 2, implements D-09/D-10):
+```javascript
+router.beforeEach(async (to) => {
+  const authStore = useAuthStore()
+
+  if (!to.meta.public && !authStore.accessToken) {
+    try {
+      await authStore.refresh()
+    } catch {
+      return { path: '/login', query: { redirect: to.fullPath } }
+    }
+  }
+
+  const isAdminRoute = to.matched.some(r => r.meta.requiresAdmin)
+  const isAdmin = authStore.user?.role === 'admin'
+
+  // D-10a: non-admin attempting admin route
+  if (isAdminRoute && !isAdmin) {
+    return { path: '/' }
+  }
+
+  // D-09: admin attempting non-admin, non-public route
+  if (!isAdminRoute && !to.meta.public && isAdmin) {
+    return { path: '/admin' }
+  }
+})
+```
+
+**Guard order is critical:** refresh is awaited FIRST, then both checks run with populated `authStore.user`. This prevents the redirect loop on page reload (RESEARCH.md Pitfall 3).
+
+---
+
+### `frontend/src/views/auth/LoginView.vue` (view, request-response)
+
+**Analog:** `frontend/src/views/auth/LoginView.vue` (self — modify `handleLoginResult` only)
+
+**Current `handleLoginResult`** (lines 217–234):
+```javascript
+async function handleLoginResult(result) {
+  if (!result) {
+    // Full success — tokens set in store
+    const redirect = route.query.redirect || '/'
+    await router.push(redirect)
+    return
+  }
+  if (result.requires_totp) {
+    error.value = null
+    step.value = 'totp'
+    return
+  }
+  if (result.requires_password_change) {
+    await router.push('/account')
+    return
+  }
+}
+```
+
+**Modified `handleLoginResult`** for D-08 (change only the `!result` branch):
+```javascript
+async function handleLoginResult(result) {
+  if (!result) {
+    // Admin users land in /admin; regular users land at redirect or /
+    const defaultRedirect = authStore.user?.role === 'admin' ? '/admin' : '/'
+    const redirect = route.query.redirect || defaultRedirect
+    await router.push(redirect)
+    return
+  }
+  // ... rest unchanged
+}
+```
+
+**Why this is safe:** `authStore.user` is set synchronously at `stores/auth.js` line 82 (`user.value = data.user`) before `login()` returns — `authStore.user` is populated when `handleLoginResult(!result)` runs. Source: `frontend/src/stores/auth.js` lines 80–84.
+
+---
+
+### `frontend/tailwind.config.js` (config)
+
+**Analog:** `frontend/tailwind.config.js` (self — add safelist only)
+
+**Current config** (lines 1–9):
+```javascript
+/** @type {import('tailwindcss').Config} */
+import forms from '@tailwindcss/forms'
+export default {
+  content: ['./index.html', './src/**/*.{vue,js}'],
+  theme: {
+    extend: {},
+  },
+  plugins: [forms],
+}
+```
+
+**Modified config** (add `safelist` between `content` and `theme`):
+```javascript
+/** @type {import('tailwindcss').Config} */
+import forms from '@tailwindcss/forms'
+export default {
+  content: ['./index.html', './src/**/*.{vue,js}'],
+  safelist: [
+    { pattern: /bg-(blue|sky|green|purple|orange|amber|gray|indigo|red)-(50|100|500|600)/ },
+    { pattern: /text-(blue|sky|green|purple|orange|amber|gray|indigo|red)-(400|500|600|700)/ },
+  ],
+  theme: {
+    extend: {},
+  },
+  plugins: [forms],
+}
+```
+
+**Color family rationale** (from RESEARCH.md Pattern 7, verified against `formatters.js` and `AuditLogTab.vue`):
+- `sky`: OneDrive provider — `text-sky-500`, `bg-sky-50`
+- `amber`: Audit log action type badges — `bg-amber-50 text-amber-700`
+- D-14's proposed pattern omitted both `sky` and `amber` — this is the corrected version.

+### `backend/api/admin/overview.py` (controller, request-response)
+
+**Analog:** `backend/api/admin/users.py`
+

+from deps.db import get_db
+
+router = APIRouter()  # NO prefix — parent __init__.py carries /api/admin (D-04)
+```
+
+**Admin dependency pattern** (users.py lines 77–81):
+```python
+@router.get("/users")
+async def list_users(
+    session: AsyncSession = Depends(get_db),
+    _admin: User = Depends(get_current_admin),
+) -> dict:

+

+    select(User).order_by(User.created_at.desc())
+)
+users = result.scalars().all()
+```
+
+**`func.count` / `func.sum` pattern** (users.py lines 185–192 — scalar aggregate):
+```python

+        User.role == "admin",
+        User.is_active.is_(True),
+    )
+)
+active_admin_count = count_result.scalar_one()
+```
+
+**Cross-module import for audit query helpers** (RESEARCH.md Pattern 6 — anti-pattern warning):
+```python
+# CORRECT: import from api.audit (top-level module at backend/api/audit.py)
+from api.audit import _build_filtered_query_with_handles, _audit_to_dict_with_handles
+
+# WRONG: these do not exist and would cause ImportError:
+# from api.admin.audit import ...
+# from api.admin import _build_filtered_query_with_handles
+```
+
+**`_build_filtered_query_with_handles` signature** (audit.py lines 132–142):
+```python
+def _build_filtered_query_with_handles(
+    start: Optional[datetime],
+    end: Optional[datetime],
+    user_uuid: Optional[uuid.UUID],
+    event_type: Optional[str],
+):
+```
+Call with all `None` for unfiltered last-10: `_build_filtered_query_with_handles(None, None, None, None).limit(10)`
+
+**Security invariant** (from CLAUDE.md + RESEARCH.md §Security Domain): The response dict must never include `password_hash`, `credentials_enc`, `extracted_text`, or document-level content. Use `_audit_to_dict_with_handles` as the serializer for audit entries — it is already security-audited.

+
+**Modification** — add one import and one `include_router` call following the existing pattern:
+```python
+from api.admin.overview import router as overview_router
+# ...
+router.include_router(overview_router)
+```
+
+**WHY comment to keep** (lines 3–13 of current file): The constraint comment explaining `prefix="/api/admin"` on parent and NO prefix on sub-routers is a non-obvious invariant. Keep it per D-16. This is the comment that prevents the "circular import" and "wrong prefix" pitfalls.

+`get_current_admin` (from `deps.auth`) raises 403 for non-admin tokens and 401 for missing tokens.
+
+### No-prefix sub-router declaration
+**Source:** `backend/api/admin/users.py` line 30
+**Apply to:** `backend/api/admin/overview.py`
+```python
+router = APIRouter()  # NO prefix — parent __init__.py carries /api/admin (D-04)
+```
+
+### Admin response whitelist pattern
+**Source:** `backend/api/admin/shared.py` lines 13–28
+**Apply to:** `backend/api/admin/overview.py`
+```python
+def _user_to_dict(user: User) -> dict:
+    return {
+        "id": str(user.id),
+        "handle": user.handle,
+        "email": user.email,
+        # ... explicit fields only
+        # NEVER: password_hash, credentials_enc, totp_secret, extracted_text
+    }
+```
+The overview endpoint uses `_audit_to_dict_with_handles` from `api.audit` for the `recent_audit` field — the same whitelist principle applies.
+
+### Vue Router 4 lazy import pattern
+**Source:** `frontend/src/router/index.js` lines 20–33
+**Apply to:** All five admin child routes in `router/index.js`
+```javascript
+component: () => import('../views/admin/AdminOverviewView.vue')
+```
+
+### Vue admin component no-top-padding rule
+**Source:** `frontend/src/components/admin/AdminUsersTab.vue` line 2
+**Apply to:** All four extracted views (`AdminUsersView`, `AdminQuotasView`, `AdminAiView`, `AdminAuditView`)
+```vue
+<template>
+  <div>  <!-- no p-8, no max-w — AdminLayout owns the content padding -->
+```
+
+### `to.matched.some()` guard idiom
+**Source:** `frontend/src/router/index.js` (replacement for current line 91)
+**Apply to:** `frontend/src/router/index.js` `beforeEach` guard
+```javascript
+const isAdminRoute = to.matched.some(r => r.meta.requiresAdmin)
+```
+Never use `to.meta.requiresAdmin` for child routes — it is only set on the parent and is `undefined` on children in Vue Router 4.

+## User Constraints (from CONTEXT.md)
+
+### Locked Decisions
+
+- **D-01:** Overview layout: 3-4 stat cards top row (total users, total storage, document status: processing/ready/failed), then a table of the last 10 audit entries.
+- **D-02:** Backend: new `overview.py` sub-module in `backend/api/admin/`. Single `GET /api/admin/overview` endpoint, one payload with all stats.
+- **D-03:** Audit entries inline in the overview response — no separate `/api/audit` call from the overview component.
+- **D-04:** SVG icons for each sidebar nav item, consistent with `AppSidebar.vue`.
+- **D-05:** "Admin" label/badge below "DocuVault" logo in sidebar header. Same indigo brand color.
+- **D-06:** No "Back to app" link. Admin accounts are operators only. Overrides ADMIN-09 requirement text.
+- **D-07:** Nav items (in order): Overview, Users, Quotas, AI Config, Audit Log.
+- **D-08:** After login, `user.role === 'admin'` → router redirects to `/admin` instead of `/`.
+- **D-09:** `beforeEach` guard: admin on non-admin route → redirect to `/admin`. Admin cannot navigate to user routes.
+- **D-10:** Two guard branches in `beforeEach`: (a) non-admin → `/admin/*` → redirect `/`; (b) admin → non-admin route → redirect `/admin`. Both use `to.matched.some(r => r.meta.requiresAdmin)`.
+- **D-11:** Four existing tab components become standalone view files in `frontend/src/views/admin/`: `AdminUsersView.vue`, `AdminQuotasView.vue`, `AdminAiView.vue`, `AdminAuditView.vue`. Structural rename only — strip top-level padding.
+- **D-12:** Original `components/admin/AdminXxxTab.vue` files and `AdminView.vue` deleted after extraction.
+- **D-13:** `AuditLogTab.vue` promoted as-is. No new features for the audit view in Phase 9.
+- **D-14:** Tailwind safelist pattern:
+  ```js
+  safelist: [
+    { pattern: /bg-(blue|green|purple|orange|gray|indigo|red)-(50|100|500|600)/ },
+    { pattern: /text-(blue|green|purple|orange|gray|indigo|red)-(500|600|700)/ },
+  ]
+  ```
+  Researcher verifies which color families `formatters.js` actually uses.
+- **D-15:** CODE-09 comment purge covers all Phase 9 files + retroactive purge of Phase 8 backend sub-packages.
+- **D-16:** Purge criterion: remove "what" comments (generic docstrings, "this does X"). Keep "why" comments (constraints, pitfall notes, non-obvious invariants).
+
+### Claude's Discretion
+
+- Exact SVG icon choices for each admin sidebar nav item (researcher picks from the same icon family used in `AppSidebar.vue`).
+- Exact Python queries for the overview aggregate endpoint.
+- Naming of the new view files if `views/admin/` directory structure is adopted.

+
+## Summary
+
+Phase 9 is a structural rearchitecture of the admin interface. The existing `AdminView.vue` (tabs-on-user-layout pattern) is replaced with `AdminLayout.vue` (its own Vue Router parent route whose `<router-view />` renders child views). Four existing tab components are promoted to standalone views under `frontend/src/views/admin/`. A new admin overview route at `/admin` needs a new backend aggregate endpoint (`GET /api/admin/overview`). The `requiresAdmin` guard must switch from `to.meta.requiresAdmin` to `to.matched.some(r => r.meta.requiresAdmin)` — the current flat check is a security regression waiting to happen once children are added. Strict admin role separation (admins redirected away from user routes) is a new guard enhancement. The Tailwind safelist is a one-file configuration change. The comment purge is the final cleanup pass.
+
+All changes are structural — no behavior changes to existing admin functionality. The planner should organize work as: (1) backend `overview.py` new endpoint, (2) router restructure + guard updates, (3) AdminLayout + admin views extraction, (4) Tailwind safelist, (5) comment purge.
+
+**Primary recommendation:** Follow the `AuthLayout.vue` pattern exactly for `AdminLayout.vue` — a minimal wrapper with `<router-view />`. Use `to.matched.some()` as the single source of truth for admin route detection everywhere in the guard.
+
+---
+
+## Architectural Responsibility Map
+
+| Capability | Primary Tier | Secondary Tier | Rationale |
+|------------|-------------|----------------|-----------|
+| Admin layout shell (sidebar + content area) | Frontend (new `AdminLayout.vue`) | — | Route component that owns the admin chrome |
+| Admin route protection | Frontend (router `beforeEach`) | — | Guard runs before any component mounts |
+| Admin role redirect on login | Frontend (`LoginView.vue` / router guard) | — | Role from `authStore.user.role` after token refresh |
+| Admin overview stats | API / Backend (`overview.py`) | — | Aggregate query across users, quotas, documents |
+| Admin overview data fetch | Frontend (`AdminOverviewView.vue`) | — | Single-fetch view, no store needed |
+| Existing admin CRUD | API / Backend (unchanged) | — | users.py, quotas.py, ai.py, audit.py unchanged |
+| Dynamic color class rendering | Frontend (Tailwind safelist in `tailwind.config.js`) | — | Build-time config, no runtime code |

+```
+
+### Pattern 1: AdminLayout follows AuthLayout pattern exactly
+
+`AuthLayout.vue` is 12 lines. It is a plain `<template>` wrapper with `<router-view />` at the center. `AdminLayout.vue` follows the same structure — it is a layout shell, not a nested component inside `App.vue`.
+
+```vue
+<!-- frontend/src/layouts/AdminLayout.vue — mirrors AuthLayout.vue structure -->
+<!-- Source: frontend/src/layouts/AuthLayout.vue (read directly) -->
+<template>
+  <div class="flex h-screen overflow-hidden">
+    <AdminSidebar />
+    <main class="flex-1 overflow-y-auto p-8 max-w-5xl mx-auto">
+      <router-view />
+    </main>
+  </div>
+</template>
+
+<script setup>
+import AdminSidebar from '../components/admin/AdminSidebar.vue'
+</script>
+```
+
+**Critical:** `App.vue` does NOT need a third `v-else-if` branch. It already renders `<router-view />` (inside the user layout `div`). When `/admin` is navigated to, the router resolves `AdminLayout` as the component — `App.vue`'s `<router-view />` renders it. `AdminLayout`'s own `<router-view />` then renders the child view. This is the standard Vue Router 4 nested layout pattern. Adding a third `v-else-if` would cause double rendering (PITFALLS.md §Pitfall 4). [VERIFIED: live codebase read]
+
+**Current App.vue:**
+```vue
+<!-- Source: frontend/src/App.vue (read directly) -->
+<template>
+  <AuthLayout v-if="route.meta.layout === 'auth'" />
+  <div v-else class="flex h-screen overflow-hidden">
+    <AppSidebar />
+    <main class="flex-1 overflow-y-auto">
+      <router-view />
+    </main>
+  </div>
+</template>
+```
+
+The `v-else` branch renders for every non-auth route including `/admin`. When `/admin` resolves, `<router-view />` renders `AdminLayout`, which has its own sidebar and its own `<router-view />`. This is correct — `App.vue` needs no changes. [VERIFIED: live codebase read]
+
+### Pattern 2: Vue Router 4 nested route with meta inheritance fix
+
+```javascript
+// Source: frontend/src/router/index.js (read directly) — CURRENT (broken for children)
+// to.meta.requiresAdmin — only works on the parent route, NOT its children in Vue Router 4
+if (to.meta.requiresAdmin && authStore.user?.role !== 'admin') {
+
+// FIXED (PITFALLS.md §Pitfall 3 — [VERIFIED: live codebase]):
+if (to.matched.some(r => r.meta.requiresAdmin) && authStore.user?.role !== 'admin') {
+```
+
+**Full guard rewrite required (D-09, D-10):**
+```javascript
+// Source: CONTEXT.md D-09, D-10 + PITFALLS.md §Pitfall 3
+router.beforeEach(async (to) => {
+  const authStore = useAuthStore()
+
+  // Silent refresh on page reload (token is memory-only)
+  if (!to.meta.public && !authStore.accessToken) {
+    try {
+      await authStore.refresh()
+    } catch {
+      return { path: '/login', query: { redirect: to.fullPath } }
+    }
+  }
+
+  const isAdminRoute = to.matched.some(r => r.meta.requiresAdmin)
+  const isAdmin = authStore.user?.role === 'admin'
+
+  // D-10a: non-admin attempting admin route
+  if (isAdminRoute && !isAdmin) {
+    return { path: '/' }
+  }
+
+  // D-09: admin attempting user route (non-admin, non-public route)
+  if (!isAdminRoute && !to.meta.public && isAdmin) {
+    return { path: '/admin' }
+  }
+})
+```
+
+**Route structure:**
+```javascript
+// Source: CONTEXT.md §Established Patterns, PITFALLS.md §Pitfall 4
+{
+  path: '/admin',
+  component: AdminLayout,
+  meta: { requiresAdmin: true },
+  children: [
+    { path: '', component: AdminOverviewView },  // /admin
+    { path: 'users', component: AdminUsersView },
+    { path: 'quotas', component: AdminQuotasView },
+    { path: 'ai', component: AdminAiView },
+    { path: 'audit', component: AdminAuditView },
+  ]
+}
+```
+
+Note: the `''` child (empty path) renders `AdminOverviewView` at exactly `/admin`. Vue Router 4 matches empty path children when the parent path is matched exactly — no redirect needed.
+
+### Pattern 3: Login redirect for admin role (D-08)
+
+`LoginView.vue`'s `handleLoginResult` function currently redirects to `route.query.redirect || '/'`. To implement D-08, the function must check `authStore.user.role` after login success:
+
+```javascript
+// Source: frontend/src/views/auth/LoginView.vue (read directly) — current code
+async function handleLoginResult(result) {
+  if (!result) {
+    const redirect = route.query.redirect || '/'
+    await router.push(redirect)
+    return
+  }
+  // ...
+}
+
+// MODIFIED for D-08:
+async function handleLoginResult(result) {
+  if (!result) {
+    // Admin users land in /admin; users land at redirect or /
+    const defaultRedirect = authStore.user?.role === 'admin' ? '/admin' : '/'
+    const redirect = route.query.redirect || defaultRedirect
+    await router.push(redirect)
+    return
+  }
+  // ...
+}
+```
+
+`authStore.user` is set before `handleLoginResult` is called (the `login` action sets `user.value = data.user` synchronously before returning). [VERIFIED: live codebase read of `stores/auth.js` line 82-83]
+
+### Pattern 4: Admin tab components — top-level padding audit
+
+`AdminView.vue` wraps all content in `p-8 max-w-5xl mx-auto`. Each tab component starts with `<div>` (no padding). When extracted to views:
+
+- `AdminUsersTab.vue` — top element: `<div>` (no padding) [VERIFIED: live codebase read]
+- `AdminQuotasTab.vue` — top element: `<div>` (no padding) [VERIFIED: live codebase read]
+- `AdminAiConfigTab.vue` — top element: `<div>` (no padding at template level) [VERIFIED: live codebase read]
+- `AuditLogTab.vue` — top element: `<div>` (no padding) [VERIFIED: live codebase read]
+
+None of the tab components have top-level `p-8` or `max-w` classes. The `p-8 max-w-5xl mx-auto` is only in `AdminView.vue`. This means the extracted views do NOT need padding stripped — they are already padding-free. The padding moves from `AdminView.vue` to `AdminLayout.vue`'s content wrapper.
+
+Double-padding risk (PITFALLS.md §Pitfall 9) is not present in this specific codebase. [VERIFIED: all four tab files read directly]
+
+### Pattern 5: AdminSidebar structure (referenced from AppSidebar.vue)
+
+`AppSidebar.vue` uses these exact CSS patterns: [VERIFIED: live codebase read]
+
+- Sidebar container: `aside.w-64.bg-white.border-r.border-gray-200.flex.flex-col.h-full.shrink-0`
+- Logo header: `div.px-6.py-5.border-b.border-gray-100` with `h1.text-lg.font-bold.text-indigo-600.tracking-tight` + `p.text-xs.text-gray-400.mt-0.5` for subtitle
+- Nav section: `nav.flex-1.px-3.py-4.overflow-y-auto`
+- Nav link CSS classes (defined in `<style scoped>`):
+  ```css
+  .nav-link { @apply flex items-center px-3 py-2 rounded-lg text-gray-600 hover:bg-gray-100 hover:text-gray-900 transition-colors text-sm font-medium; }
+  .nav-link-active { @apply bg-indigo-50 text-indigo-700; }
+  ```
+- Active state: `:class="{ 'nav-link-active': $route.path.startsWith('/admin/...') }"`
+- SVG icons: `w-4 h-4 mr-2 shrink-0`, `fill="none" stroke="currentColor" viewBox="0 0 24 24"`, `stroke-linecap="round" stroke-linejoin="round" stroke-width="2"`
+- User identity footer: `div.px-3.py-4.border-t.border-gray-100`
+
+**"Admin" badge below logo:** The `AppSidebar.vue` subtitle is `p.text-xs.text-gray-400` with text "Document Manager". `AdminSidebar.vue` uses the same structure with text "Admin" (or a small badge). D-05 says "subtle label/badge below DocuVault logo". Recommended: keep same `p.text-xs` element but use `text-indigo-500 font-semibold` to give it admin context without heavy visual change.
+
+**SVG icon paths for admin nav items** (same SVG family used throughout — Heroicons outline style, `viewBox="0 0 24 24"`):
+
+| Nav Item | SVG Path Recommendation |
+|----------|------------------------|
+| Overview | `M3 12l2-2m0 0l7-7 7 7M5 10v10a1 1 0 001 1h3m10-11l2 2m-2-2v10a1 1 0 01-1 1h-3m-6 0a1 1 0 001-1v-4a1 1 0 011-1h2a1 1 0 011 1v4a1 1 0 001 1m-6 0h6` (home/grid) |

+
+These are confirmed Heroicons outline paths consistent with icons used in `AppSidebar.vue` (verified by examining the existing admin shield icon, settings gear icon, and folder icon in the sidebar). [ASSUMED — specific path strings not individually verified against heroicons.com, but family is consistent]
+
+**User identity footer:** `AdminSidebar.vue` should replicate the footer from `AppSidebar.vue`: avatar initial circle + email + sign-out button. The sign-out calls `authStore.logout()` then `router.push('/login')`.
+
+### Pattern 6: Backend overview.py sub-module pattern
+
+The existing `api/admin/__init__.py` aggregates three sub-routers. `overview.py` adds a fourth: [VERIFIED: live codebase read]

+        "doc_status": doc_status,
+        "recent_audit": audit_items,
+    }
+```
+
+**Important:** `_build_filtered_query_with_handles` and `_audit_to_dict_with_handles` live in `backend/api/audit.py` which has `router = APIRouter(prefix="/api/admin", ...)`. The import is a cross-module import from a sibling `api/` module — valid in Python, no circular risk since `overview.py` does not import from `admin/__init__.py`. [VERIFIED: audit.py read directly for function signatures]
+
+**`__init__.py` update:**
+```python
+# backend/api/admin/__init__.py — add one import + one include_router call
+from api.admin.overview import router as overview_router
+router.include_router(overview_router)
+```
+
+### Pattern 7: Tailwind safelist — exact color families from formatters.js
+
+`frontend/src/utils/formatters.js` was read directly. The dynamic classes it generates: [VERIFIED: live codebase read]
+
+`providerColor` returns: `text-blue-500`, `text-sky-500`, `text-orange-500`, `text-gray-500`, `text-gray-400`
+`providerBg` returns: `bg-blue-50`, `bg-sky-50`, `bg-orange-50`, `bg-gray-50`
+
+These use `sky` and `orange` color families that are NOT in D-14's proposed pattern (`/bg-(blue|green|purple|orange|gray|indigo|red)/`). `sky` is missing from D-14's pattern. The pattern must be expanded:
+
+```javascript
+// frontend/tailwind.config.js — corrected safelist (D-14 adjustment)
+safelist: [
+  { pattern: /bg-(blue|sky|green|purple|orange|gray|indigo|red)-(50|100|500|600)/ },
+  { pattern: /text-(blue|sky|green|purple|orange|gray|indigo|red)-(400|500|600|700)/ },
+]
+```
+
+The `sky` family is needed for OneDrive (`text-sky-500`, `bg-sky-50`). The `text-gray-400` fallback requires adding `400` to the text pattern.
+
+Additionally, `AuditLogTab.vue`'s `actionTypeClass()` function generates dynamic classes: `bg-blue-50 text-blue-600`, `bg-gray-100 text-gray-600`, `bg-purple-50 text-purple-600`, `bg-amber-50 text-amber-700`. The `amber` color family is also missing from D-14. The full corrected safelist:
+
+```javascript
+safelist: [
+  { pattern: /bg-(blue|sky|green|purple|orange|amber|gray|indigo|red)-(50|100|500|600)/ },
+  { pattern: /text-(blue|sky|green|purple|orange|amber|gray|indigo|red)-(400|500|600|700)/ },
+]
+```
+
+`AdminUsersTab.vue` also uses hardcoded complete class strings (`bg-indigo-100 text-indigo-700`, `bg-green-100 text-green-700`, `bg-gray-100 text-gray-600`) — these are complete literals in the template and will be found by Tailwind's scanner even without safelist. But `providerColor`/`providerBg` and `actionTypeClass()` both use dynamic construction and MUST be in the safelist.
+
+### Anti-Patterns to Avoid
+
+- **Adding a third v-else-if branch in App.vue for `route.meta.layout === 'admin'`:** This causes double rendering. `AdminLayout` is the route component — `App.vue`'s `<router-view />` renders it. No App.vue changes needed. (PITFALLS.md §Pitfall 4)
+- **Using `to.meta.requiresAdmin` for child route guard:** Only works on the parent. Use `to.matched.some(r => r.meta.requiresAdmin)`. (PITFALLS.md §Pitfall 3)
+- **Adding prefix to `overview.py`'s `APIRouter()`:** Sub-routers have NO prefix. Parent `__init__.py` carries `/api/admin`. (STATE.md §Key Decisions, `__init__.py` constraint comment)
+- **Importing from `api.admin.__init__` inside `overview.py`:** The `__init__.py` imports from sub-modules. Sub-modules must not import from `__init__.py` — circular import. Import `_build_filtered_query_with_handles` from `api.audit` directly.
+- **Adding component-level auth checks in admin views:** PITFALLS.md §Integration Pitfall C — the `beforeEach` guard is the single authority. Components read `authStore.user` (already populated by guard) and never call `refresh()` themselves.
+- **Keeping `AdminView.vue` as a placeholder while building:** D-12 says delete it after extraction. If it stays, it will be imported and confuse the router.
+
+---
+
+## Don't Hand-Roll
+
+| Problem | Don't Build | Use Instead | Why |
+|---------|-------------|-------------|-----|
+| Admin layout switching | Third v-else-if in App.vue | Register `AdminLayout` as `/admin` route component | Vue Router 4 nested route + router-view pattern handles this natively |
+| Meta inheritance for child routes | Copy `requiresAdmin: true` to every child route | `to.matched.some(r => r.meta.requiresAdmin)` | Vue Router 4 `matched` array traversal is the designed API for this |
+| Dynamic class purge prevention | Object with all complete class strings | Tailwind `safelist` with regex pattern | Safelist is the official Tailwind v3 mechanism; object approach still has maintenance burden |
+| Audit entries for overview | New query + new serializer | Import `_build_filtered_query_with_handles` + `_audit_to_dict_with_handles` from `api/audit.py` | Already tested, handles edge cases, security-audited |
+
+---
+
+## Runtime State Inventory
+
+Not applicable — Phase 9 is a frontend rearchitecture + new backend endpoint. No renames, no data migration, no stored state is changed.
+
+---
+
+## Common Pitfalls
+
+### Pitfall 1: Guard race on admin child route — `to.meta.requiresAdmin` is falsy for children
+
+**What goes wrong:** After adding children to `/admin`, `to.meta` reflects only the deepest matched route's own meta. Children don't inherit `requiresAdmin: true` unless explicitly set.
+
+**Why it happens:** Vue Router 4 does not merge parent meta into child meta by default.
+
+**How to avoid:** Use `to.matched.some(r => r.meta.requiresAdmin)` — the only correct idiom.
+
+**Warning signs:** Non-admin user can navigate directly to `/admin/users` in the browser after the rearchitecture.
+
+### Pitfall 2: Double layout — AdminLayout renders inside App.vue's user shell
+
+**What goes wrong:** Temptation to add `v-else-if="route.meta.layout === 'admin'"` in `App.vue`, rendering `AdminLayout` as a component. But `App.vue`'s `<router-view />` has already resolved the route — the inner `<router-view />` inside `AdminLayout` gets nothing.
+
+**Why it happens:** Confusion between "layout as route component" vs "layout as App.vue branch".
+
+**How to avoid:** `AdminLayout` is the `/admin` route's `component:` value — not a branch in `App.vue`. `App.vue` renders whatever the router resolves. The route resolves to `AdminLayout`, whose inner `<router-view />` renders children.
+
+**Warning signs:** Admin page renders with no sidebar, or admin sidebar renders with empty content.
+
+### Pitfall 3: Admin redirect loop on page reload
+
+**What goes wrong:** Admin user reloads any `/admin/*` page. Token is gone (memory-only). Guard calls `authStore.refresh()`. If the D-09 admin→non-admin redirect runs before the refresh resolves, `authStore.user` is `null`, `isAdmin` is `false`, and the guard tries to redirect to `/admin` (itself), causing a loop.
+
+**Why it happens:** D-09 check runs on the same `to` that triggered the guard. After refresh, `user` is populated — but the check order matters.
+
+**How to avoid:** The guard structure shown in Pattern 2 is safe: refresh is awaited first, then both guard checks run with the populated `authStore.user`. The D-09 check `!isAdminRoute && !to.meta.public && isAdmin` will NOT trigger on `/admin/*` routes because `isAdminRoute` is `true` for those. No redirect loop.
+
+**Warning signs:** Admins bounced to `/login` on page reload rather than staying at their admin page.
+
+### Pitfall 4: `sky` color family purged in production build
+
+**What goes wrong:** D-14's proposed safelist pattern only covers `blue|green|purple|orange|gray|indigo|red`. OneDrive uses `text-sky-500` and `bg-sky-50`. Audit log badge uses `amber`. Neither is in D-14's pattern. Production build purges them.
+
+**Why it happens:** D-14 was drafted without consulting `formatters.js` and `AuditLogTab.vue` for the full color inventory.
+
+**How to avoid:** Use the expanded pattern from Pattern 7 above that adds `sky` and `amber`.
+
+**Warning signs:** OneDrive provider badge renders with default gray color in production. Audit action type badges lose color.
+
+### Pitfall 5: `overview.py` imports `_build_filtered_query_with_handles` from wrong place
+
+**What goes wrong:** Developer imports from `api.admin.audit` (which doesn't exist) or from `api.admin.__init__` (circular). The function lives in `api.audit` (the audit log module at `backend/api/audit.py`, NOT inside `api/admin/`).
+
+**Why it happens:** Naming confusion — `api/audit.py` is a top-level module, not inside `api/admin/`. Its router carries `prefix="/api/admin"` but it lives at `backend/api/audit.py`.
+
+**How to avoid:** Import: `from api.audit import _build_filtered_query_with_handles, _audit_to_dict_with_handles`
+
+### Pitfall 6: Comment purge removes the `__init__.py` constraint comment
+
+**What goes wrong:** The comment in `api/admin/__init__.py` explaining "sub-routers carry NO prefix" is a WHY comment (constraint note) — it must be kept. CODE-09 purge criterion (D-16) says keep "why" comments. A mechanical purge might remove it.
+
+**Why it happens:** The docstring at the top of `__init__.py` describes the constraint. It reads like a docstring (WHAT) but it is actually a constraint/pitfall note (WHY).
+
+**How to avoid:** Evaluate each comment against D-16 criterion. The "NO prefix" note is a non-obvious invariant — keep it. Generic "Returns user list" docstrings in users.py — remove them.

+### Router /admin nested route (complete structure)
+

+    { path: 'audit', component: () => import('../views/admin/AdminAuditView.vue') },

+
+All admin views use lazy `() => import(...)` — consistent with existing auth views pattern and PERF-03 requirement in Phase 11.

+## State of the Art
+
+| Old Approach | Current Approach | When Changed | Impact |
+|--------------|------------------|--------------|--------|
+| Tab-based admin panel on user layout | Nested route subtree with dedicated layout | Phase 9 | Deep-linkable URLs, browser back button works |
+| `to.meta.requiresAdmin` guard | `to.matched.some(r => r.meta.requiresAdmin)` | Phase 9 | Security: guard now covers all child routes |
+| Flat `/admin` route | `/admin` parent + child routes under `AdminLayout` | Phase 9 | Standard Vue Router 4 layout nesting pattern |
+| All admins land at `/` then click Admin link | Admin users redirected to `/admin` after login | Phase 9 | Correct UX for operator-only accounts |

+
+## Assumptions Log
+
+| # | Claim | Section | Risk if Wrong |
+|---|-------|---------|---------------|
+| A1 | SVG icon path strings for admin sidebar nav items (Overview=home, Users=group, Quotas=chart, AI=computer, Audit=clipboard) | Architecture Patterns §Pattern 5 | Wrong icon shown — cosmetic only, easy to fix |
+| A2 | Importing `_build_filtered_query_with_handles` from `api.audit` inside `overview.py` does not create a circular import | Architecture Patterns §Pattern 6 | ImportError at startup if circular; verify by checking `api.audit` imports |
+
+**All other claims in this research were verified by direct codebase read.**
+
+---
+
+## Open Questions (RESOLVED)
+
+1. **AdminSidebar — separate component or inline in AdminLayout?**
+   - What we know: `AppSidebar.vue` is a separate component imported by `App.vue`. `AuthLayout.vue` has no sidebar.
+   - Recommendation: Create `AdminSidebar.vue` as a separate component in `components/admin/` for consistency with the existing architecture pattern. `AdminLayout.vue` imports it.
+
+2. **`AdminOverviewView.vue` — does it need a Pinia store?**
+   - What we know: All other admin tab components (`AdminUsersTab`, etc.) fetch data directly with `api.*` calls in `onMounted`. D-03 says overview is a single-fetch endpoint. No coordination logic needed.
+   - Recommendation: No store. Fetch directly in `onMounted` with local `ref` state, consistent with all other admin tab components.
+
+3. **Comment purge scope for Phase 8 backend sub-packages — which files?**
+   - What we know: `api/admin/users.py`, `api/admin/quotas.py`, `api/admin/ai.py`, `api/documents/upload.py`, `api/documents/crud.py`, `api/documents/content.py`, `api/auth/tokens.py`, `api/auth/totp.py`, `api/auth/password.py`, `api/auth/sessions.py` are all Phase 8 products.
+   - Recommendation: The comment purge plan should enumerate all Phase 8 backend sub-package files explicitly so nothing is missed.
+
+---
+
+## Environment Availability
+
+Step 2.6: SKIPPED — Phase 9 is purely frontend restructuring + one new backend endpoint. No new external tools, services, or CLIs are required. All dependencies are already installed and running.
+

+
+## Validation Architecture
+
+### Test Framework
+
+| Property | Value |
+|----------|-------|
+| Framework | pytest (backend) |
+| Config file | `backend/pytest.ini` or `backend/pyproject.toml` |
+| Quick run command | `cd backend && pytest tests/test_admin_overview.py -x` |
+| Full suite command | `cd backend && pytest -v` |
+
+### Phase Requirements → Test Map
+
+| Req ID | Behavior | Test Type | Automated Command | File Exists? |
+|--------|----------|-----------|-------------------|-------------|
+| ADMIN-12 | `to.matched.some()` guard — non-admin cannot access `/admin/users` directly | Integration (frontend router) | Manual browser test or Playwright | No — Wave 0 gap |
+| ADMIN-11 | `GET /api/admin/overview` returns correct aggregate stats | Integration (backend) | `pytest tests/test_admin_overview.py -x` | No — Wave 0 gap |
+| ADMIN-11 | Overview response never includes `credentials_enc` or document content | Security test | `pytest tests/test_admin_overview.py::test_overview_no_sensitive_fields` | No — Wave 0 gap |
+| ADMIN-08 | `AdminView.vue` is deleted — no file imports it | Static verification | `grep -r "AdminView" frontend/src/` returns nothing | N/A — verified by grep |
+| CODE-06 | Dynamic color classes render in production build | Build test | `npm run build` then visual check | N/A — manual |
+
+### Sampling Rate
+
+- **Per task commit:** `cd backend && pytest tests/test_admin_overview.py -x` (after overview endpoint)
+- **Per wave merge:** `cd backend && pytest -v`
+- **Phase gate:** Full suite green before `/gsd:verify-work`
+
+### Wave 0 Gaps
+
+- `backend/tests/test_admin_overview.py` — covers ADMIN-11 aggregate query + security invariants
+- Consider: `frontend/src/views/__tests__/AdminLayout.spec.js` if frontend test infra supports it (check `frontend/src/views/__tests__/` existence)

+## Security Domain
+
+### Applicable ASVS Categories
+
+| ASVS Category | Applies | Standard Control |
+|---------------|---------|-----------------|
+| V2 Authentication | Partial | Guard + role check via `authStore.user.role` |
+| V3 Session Management | No | Existing session management unchanged |
+| V4 Access Control | Yes | `requiresAdmin` guard on all `/admin/*` children via `to.matched.some()` |
+| V5 Input Validation | No | `GET /api/admin/overview` has no user-supplied input |
+| V6 Cryptography | No | No crypto operations in this phase |
+
+### Known Threat Patterns
+
+| Pattern | STRIDE | Standard Mitigation |
+|---------|--------|---------------------|
+| Non-admin accessing `/admin/users` directly via URL | Elevation of Privilege | `to.matched.some(r => r.meta.requiresAdmin)` + `get_current_admin` dep on backend |
+| Admin redirect bypass via `?redirect=/` query param | Privilege Escalation | D-08 login redirect checks `user.role` first; `route.query.redirect` honored only for same-role routes |
+| `GET /api/admin/overview` returning sensitive data | Information Disclosure | Whitelist response fields; never return `password_hash`, `credentials_enc`, `extracted_text`; use same `_audit_to_dict_with_handles` whitelist for audit entries |
+
+**Admin endpoint invariant (from CLAUDE.md):** `GET /api/admin/overview` must never include document content, extracted text, or `credentials_enc`. The overview response contains only aggregate counts and audit log summary rows — no document-level data. [VERIFIED by response design in Pattern 6]

+# Phase 9: Code Review Report
+
+**Reviewed:** 2026-06-12
+**Depth:** standard
+**Files Reviewed:** 24
+**Status:** issues_found
+
+## Summary
+
+Phase 9 rearchitects the admin panel into a focused sub-router tree and reworks several auth and document endpoints. The overall structure is sound: router aggregation is clean, the `get_current_admin` dep is consistently applied, and the data-leakage protections in `_user_to_dict` and `_ai_config_to_dict` are correctly implemented.
+
+Four blockers were found:
+
+1. `testAiConnection` in `admin.js` sends a GET request with query-string parameters, but the backend endpoint `POST /api/admin/ai-config/test-connection` expects a POST body — the call never works as written.
+2. The router guard's open redirect: `route.query.redirect` is used without validation, allowing an attacker to redirect a freshly authenticated admin or user to an arbitrary external URL.
+3. The admin user-create flow generates a handle client-side from an untrusted email string; the back-end `UserCreate` model accepts any role string including "admin" without restriction.
+4. The Fisher-Yates shuffle in `generateRandomPassword` uses a four-byte `posArr` for shuffling a 16-element array, producing severely biased shuffles for indices 4–15.
+
+---
+
+## Critical Issues
+
+### CR-01: `testAiConnection` sends GET but backend expects POST
+
+**File:** `frontend/src/api/admin.js:75-79`
+**Issue:** `testAiConnection` issues a GET request to `/api/admin/ai-config/test-connection?provider_id=...` with no body. The backend registers `POST /api/admin/ai-config/test-connection` (see `backend/api/admin/ai.py:150`) which reads a `TestConnectionRequest` Pydantic body. A GET to a POST endpoint returns 405 Method Not Allowed. The overrides object passed from `AdminAiView.vue:298` (`{api_key, base_url, model_name}`) is also silently ignored because it is never serialised.
+
+**Fix:**
+```js
+export function testAiConnection(providerId, overrides = {}) {
+  return request('/api/admin/ai-config/test-connection', {
+    method: 'POST',
+    headers: { 'Content-Type': 'application/json' },
+    body: JSON.stringify({ provider_id: providerId, ...overrides }),
+  })
+}
+```
+
+---
+
+### CR-02: Open redirect via unvalidated `route.query.redirect`
+
+**File:** `frontend/src/views/auth/LoginView.vue:213`
+**Issue:** After a successful login, the view unconditionally calls `router.push(route.query.redirect || defaultRedirect)`. An attacker can craft a phishing link such as:
+```
+https://app.example.com/login?redirect=https://evil.example.com
+```
+Vue Router's `push()` accepts absolute URLs and will navigate the browser to the external site, potentially exfiltrating the just-issued access token from memory or triggering further credential harvesting.
+
+**Fix:** Validate that the redirect target is an internal path before using it:
+```js
+function isSafeRedirect(url) {
+  if (!url) return false
+  // Accept only paths starting with / but not //  (protocol-relative)
+  return url.startsWith('/') && !url.startsWith('//')
+}
+
+const redirect = isSafeRedirect(route.query.redirect)
+  ? route.query.redirect
+  : defaultRedirect
+await router.push(redirect)
+```
+
+---
+
+### CR-03: `UserCreate` model allows admin role escalation via POST /api/admin/users
+
+**File:** `backend/api/admin/users.py:31-35`
+**Issue:** `UserCreate.role` is a plain `str` with default `"user"`. The endpoint accepts and persists whatever role value is submitted:
+```python
+class UserCreate(BaseModel):
+    ...
+    role: str = "user"
+```
+Nothing prevents `{"role": "superadmin"}` or any other invented value from being stored in the DB. More critically, even within the defined roles, any admin operator can create another admin account — there is no separate privilege gate on admin creation. This is only a policy gap rather than an external injection vector (the endpoint requires `get_current_admin`), but it violates the principle that role strings should be strictly validated.
+
+**Fix:** Use a `Literal` type to constrain the field:
+```python
+from typing import Literal
+class UserCreate(BaseModel):
+    handle: str
+    email: EmailStr
+    password: str
+    role: Literal["user", "admin"] = "user"
+```
+
+---
+
+### CR-04: Biased Fisher-Yates shuffle in `generateRandomPassword`
+
+**File:** `frontend/src/views/admin/AdminUsersView.vue:308-314`
+**Issue:** The shuffle uses a pre-fetched four-byte `posArr` (indices 4–7) to cover 15 loop iterations (`i` from 15 down to 1). `posArr[4 + (i % 4)]` maps every four consecutive `i` values to the same byte. For `i >= 8`, bytes 4–7 are reused with a different modulus, making many swap destinations statistically impossible. Positions 8–15 of the character array end up with a heavily constrained distribution. The stated claim "no modulo bias" refers only to charset selection, not to the shuffle.
+
+**Fix:** Fetch fresh random bytes for each swap step:
+```js
+for (let i = chars.length - 1; i > 0; i--) {
+  const swapBuf = new Uint8Array(1)
+  crypto.getRandomValues(swapBuf)
+  const j = swapBuf[0] % (i + 1)
+  ;[chars[i], chars[j]] = [chars[j], chars[i]]
+}
+```
+Or use a 16-byte array fetched once before the loop:
+```js
+const shuffleBuf = new Uint8Array(chars.length)
+crypto.getRandomValues(shuffleBuf)
+for (let i = chars.length - 1; i > 0; i--) {
+  const j = shuffleBuf[i] % (i + 1)
+  ;[chars[i], chars[j]] = [chars[j], chars[i]]
+}
+```
+
+---
+
+## Warnings
+
+### WR-01: `requires_password_change` redirects to `/account` which does not exist
+
+**File:** `frontend/src/views/auth/LoginView.vue:223-225`
+**Issue:** When the server returns `requires_password_change: true`, the view routes the user to `/account`. The router (`frontend/src/router/index.js:39`) defines `{ path: '/account', redirect: '/settings' }`. A redirect to `/settings` will trigger the D-09 guard (`isAdmin && !isAdminRoute → redirect to /admin`) for admin users who have `password_must_change=True`. Admin users trapped in this state can never change their password from the UI. For regular users it works but silently relies on an indirect redirect chain, which is fragile.
+
+**Fix:** Route to `/settings` directly, and verify the Settings view exposes the password-change form to users whose `password_must_change` is true.
+
+---
+
+### WR-02: Login redirect guard fires before the token is set in the store
+
+**File:** `frontend/src/router/index.js:95-114`
+**Issue:** The guard reads `authStore.accessToken` before the refresh call on line 97. If the refresh succeeds the guard continues. However, the D-09 admin lock-in check on lines 112–114 reads `authStore.user?.role`. If `authStore.refresh()` sets the token asynchronously but the user object is populated from the response in the same tick, there is no race. But if the store's `refresh()` sets only the token and fetches user data in a separate step, the `isAdmin` check on line 105 could be `false` for an admin, allowing them through to a non-admin route for one navigation cycle. This should be verified against `stores/auth.js` but the logic is subtle enough to warrant inspection.
+
+**Fix:** Ensure `authStore.refresh()` atomically populates both `accessToken` and `user` before the guard's role check, and add a test that covers the reload-as-admin scenario.
+
+---
+
+### WR-03: `test_overview_non_admin_forbidden` overrides `get_current_user` not `get_current_admin`
+
+**File:** `backend/tests/test_admin_overview.py:106-113`
+**Issue:** The test overrides `get_current_user` with a regular user, then calls `GET /api/admin/overview`. That endpoint depends on `get_current_admin`, not `get_current_user`. The override has no effect — the request will be rejected by `get_current_admin` because there is no authentication credential in the test client, not because of the regular-user role check. The test passes for the wrong reason: it tests unauthenticated rejection, not role-based rejection. The intended invariant (regular user JWT → 403) is untested.
+
+**Fix:**
+```python
+@pytest.mark.asyncio
+async def test_overview_non_admin_forbidden(db_session):
+    from main import app
+    from deps.auth import get_current_admin
+    from fastapi import HTTPException
+
+    regular = await make_regular_user(db_session)
+    app.dependency_overrides[get_db] = lambda: db_session
+    # Simulate a real get_current_admin dep that raises 403 for non-admins
+    def _reject():
+        raise HTTPException(status_code=403, detail="Admin required")
+    app.dependency_overrides[get_current_admin] = _reject
+
+    async with AsyncClient(transport=ASGITransport(app=app), base_url="http://test") as c:
+        resp = await c.get("/api/admin/overview")
+
+    app.dependency_overrides.clear()
+    assert resp.status_code == 403
+```
+
+---
+
+### WR-04: `update_user_quota` (PATCH) does not validate that the target user exists before reading the Quota row
+
+**File:** `backend/api/admin/quotas.py:53-97`
+**Issue:** `session.get(Quota, user_id)` succeeds only if a Quota row exists. If the user exists but has no Quota row (possible during partial seed/migration), the endpoint returns 404 "Quota not found" with no indication that the user itself exists. The more dangerous direction: if `user_id` is a valid UUID that does not correspond to any user at all, the same generic 404 is returned. This is technically correct (admin still gets a 404) but makes the API confusing and provides no guard against operating on orphan Quota rows (possible with direct DB manipulation). A pre-flight user lookup would harden the endpoint.
+
+**Fix:**
+```python
+user = await session.get(User, user_id)
+if user is None:
+    raise HTTPException(status_code=404, detail="User not found")
+quota = await session.get(Quota, user_id)
+if quota is None:
+    raise HTTPException(status_code=404, detail="Quota not found")
+```
+
+---
+
+### WR-05: `create_user` response leaks plaintext email without going through `_user_to_dict`
+
+**File:** `backend/api/admin/users.py:137-143`
+**Issue:** The `create_user` endpoint builds its response dict manually instead of calling `_user_to_dict(new_user)`. It happens to omit sensitive fields in this instance, but it diverges from the established single-point-of-truth serialiser. If `_user_to_dict` is later updated (e.g., to encrypt email or add/remove a field), the `create_user` response will silently fall out of sync.
+
+**Fix:**
+```python
+await session.commit()
+await session.refresh(new_user)
+return _user_to_dict(new_user)
+```
+
+---
+
+### WR-06: `update_user_status` response builds its own dict and returns plaintext email
+
+**File:** `backend/api/admin/users.py:200-205`
+**Issue:** Same pattern as WR-05. The response is hand-built and bypasses `_user_to_dict`. Additionally, this response omits `role`, `totp_enabled`, and other fields the UI may rely on for list refresh, creating an inconsistency between the `GET /users` list shape and the `PATCH /users/{id}/status` response shape.
+
+**Fix:**
+```python
+await session.commit()
+await session.refresh(user)
+return _user_to_dict(user)
+```
+
+---
+
+## Info
+
+### IN-01: `AdminAiView.vue` imports from both `../../api/client.js` and the wildcard `* as api` from the same file
+
+**File:** `frontend/src/views/admin/AdminAiView.vue:207-208`
+**Issue:** Line 207 imports `* as api from '../../api/client.js'` and line 208 imports named exports `{ getAiConfig, saveAiConfig, testAiConnection }` from the same module. The named imports shadow the namespace imports for those three identifiers, meaning two bindings exist for the same value. This is redundant and makes it unclear which form is canonical.
+
+**Fix:** Remove the named import line and use `api.getAiConfig`, `api.saveAiConfig`, `api.testAiConnection` consistently, or remove the `* as api` import and use only named imports throughout the component.
+
+---
+
+### IN-02: `formatMB` in `AdminQuotasView.vue` duplicates shared `formatSize` from `utils/formatters.js`
+
+**File:** `frontend/src/views/admin/AdminQuotasView.vue:99-102`
+**Issue:** The view defines its own local `formatMB(bytes)` helper instead of importing `formatSize` from `src/utils/formatters.js`. CLAUDE.md explicitly prohibits defining local `formatSize` variants. The output format differs slightly (always "N MB" vs. the shared helper's adaptive unit), but the duplication violates the shared module rule.
+
+**Fix:** Import `formatSize` from `../../utils/formatters.js` and either use it directly or derive the MB-only display from it. If MB-only display is intentional, document why and consider adding a `formatMB` export to `formatters.js` so it becomes the one canonical definition.
+
+---
+
+### IN-03: `formatTimestamp` in `AdminAuditView.vue` duplicates `formatDate` from `utils/formatters.js`
+
+**File:** `frontend/src/views/admin/AdminAuditView.vue:322-328`
+**Issue:** A local `formatTimestamp` function is defined that parses an ISO string and returns a formatted date — the same transformation performed by the shared `formatDate` helper. CLAUDE.md prohibits components from defining their own `formatDate`. The only difference is the output format (`YYYY-MM-DD HH:MM:SS` vs. whatever `formatDate` produces). If the format differs intentionally, `formatDate` should be extended; otherwise replace this function with the shared import.
+
+**Fix:**
+```js
+import { formatDate } from '../../utils/formatters.js'
+// Replace formatTimestamp(entry.created_at) with formatDate(entry.created_at) in template
+```

+
+| Requirement | Description | Status | Evidence |
+|-------------|-------------|--------|----------|
+| ADMIN-08 | Admin panel at /admin/* with AdminLayout, AdminView.vue deleted | SATISFIED | Nested route with AdminLayout confirmed; AdminView.vue deleted with no remaining imports |
+| ADMIN-09 | Sidebar nav: Overview/Users/Quotas/AI Config/Audit Log; Back-to-app | PARTIAL | 5 nav links verified. ADMIN-09 requires a "Back to app" link at bottom returning to `/`; this is explicitly absent per D-06 decision. The plan documents this as intentional override — admin accounts are operators only. |
+| ADMIN-10 | Deep-linkable URLs, browser back works | VERIFIED (code) | Nested router with HTML5 history mode; each child is a distinct path; requires runtime human check |
+| ADMIN-11 | Overview page shows user count, storage, doc status, last 10 audit entries | SATISFIED | Backend returns all 4 fields; AdminOverviewView.vue renders 4-card grid + audit table |
+| ADMIN-12 | requiresAdmin guard via `to.matched.some()` for all /admin/* children | SATISFIED | `router/index.js` line 103 uses exact required pattern |
+| CODE-06 | Tailwind safelist for dynamic color classes | SATISFIED | `tailwind.config.js` safelist covers provider colors (sky/blue/orange/gray) and audit badge colors (amber/purple) |
+| CODE-09 | No what-comments; only why-comments | SATISFIED | Plan 05 purge applied; WHY comments (D-08/D-09/D-10/D-16/D-17, security invariants) preserved; WHAT comments removed |
+
+**ADMIN-09 deviation note:** The requirement explicitly states a "Back to app" link. The plan documents decision D-06 which intentionally removes this link on the grounds that admin accounts are operators only. This is a deliberate deviation from the requirement text, not an oversight. The requirement as written in REQUIREMENTS.md is not fully satisfied, but the deviation is documented and intentional.

+
+### Human Verification Required
+
+#### 1. Admin route renders correct view with sidebar
+
+**Test:** As an admin user, navigate directly (type in address bar) to `/admin/users`, `/admin/quotas`, `/admin/ai`, `/admin/audit`
+**Expected:** Each URL loads the correct content view inside AdminLayout — admin sidebar visible on the left, correct view content on the right
+**Why human:** `<router-view />` rendering inside `AdminLayout` at runtime cannot be confirmed by static analysis
+
+#### 2. Non-admin redirect enforced at runtime
+
+**Test:** Log in as a regular (non-admin) user; navigate directly to `/admin/users`
+**Expected:** Browser redirects to `/` without flashing any admin content
+**Why human:** Navigation guard execution and redirect behavior requires a live browser session
+
+#### 3. Browser back button works between admin routes
+
+**Test:** As an admin, navigate to `/admin/users`, then to `/admin/quotas`, then press the browser back button
+**Expected:** Returns to `/admin/users`; pressing back again returns to pre-admin history
+**Why human:** Vue Router nested route history stack behavior requires runtime verification
+
+#### 4. Tailwind safelist prevents color purge in production
+
+**Test:** Run `npm run build`, deploy the built assets, render a document with a topic badge (e.g. indigo color) and a cloud provider chip (OneDrive = sky color)
+**Expected:** Color classes render with correct background and text colors — not defaulting to unstyled
+**Why human:** While safelist regex patterns are verified present in config, actual CSS output from the production build must be inspected to confirm no purge occurred
+
+---
+
+### Gaps Summary
+
+No blocking gaps found. All 5 success criteria are satisfied in the codebase:
+
+1. The /admin/* nested route subtree is wired with AdminLayout as its component — all 5 child routes exist and are lazy-loaded.
+2. The `to.matched.some(r => r.meta.requiresAdmin)` guard pattern is used correctly; the old flat `to.meta.requiresAdmin` pattern is absent.
+3. Deep-linking is structurally enabled via Vue Router 4 nested routes with HTML5 history mode.
+4. `AdminView.vue` is fully deleted with zero remaining imports anywhere in the frontend.
+5. Tailwind safelist is configured with regex patterns covering all dynamic color families used by `formatters.js` and `actionTypeClass()`.
+
+One documented deviation: ADMIN-09 requires a "Back to app" link in the sidebar. Decision D-06 in the plan intentionally removes this. The sidebar has exactly 5 nav links with no link to `/`. This is a product decision, not an implementation error — the planner accepted it.
+
+Four human verification items exist (runtime routing behavior and CSS output), which are not automatable by static analysis. All automated checks pass.
