 ### ESLint Configuration
 
+The lint gate enforces `--max-warnings=0` — zero warnings are permitted. All warnings are treated as errors.
+
 ```bash
-# Run linter
-npm run lint
+# Run linter (enforces zero warnings)
+pnpm lint
 
 # Fix auto-fixable issues
-npm run lint:fix
+pnpm exec eslint src --fix
 ```
 
+Security rules (`security/detect-*`) are disabled project-wide with linked GitHub issues (#45–48) — they produced false positives on admin-internal API routes that are not public-facing. All other warning categories (unused vars, react-hooks/exhaustive-deps) must be clean before merging.

+# Admin Guide (Vite SPA)
+
+The nSelf admin companion (`localhost:3021`) is a local-only Vite SPA for
+managing your nSelf installation. It connects to the nSelf stack via the
+nginx health endpoint and API routes.
+
+---
+
+## Prerequisites
+
+- nSelf stack running: `nself start`
+- Admin available at: http://localhost:3021
+- Session TTL: 24 hours (password-based, LokiJS store)
+
+---
+
+## 7-State UI Contract
+
+Every admin panel implements the **7-state AsyncScreen contract**. Regardless
+of which panel you open, you will see one of these states:
+
+| State | When shown | What to do |
+|---|---|---|
+| **Loading** | Data fetch in progress | Wait |
+| **Offline** | nSelf stack not running | Run `nself start` in your terminal, then click **Check again** |
+| **Auth-expired** | 24h session ended | Enter password in the login overlay |
+| **Error** | Fetch or API failure | Click **Retry**; check logs if persistent |
+| **Empty** | No data to display | Follow the in-panel CTA |
+| **Rate-limited** | Too many requests | Wait for the timer, then retry |
+| **Ready** | Data loaded | Use the panel normally |
+
+The "Offline" state means the **nSelf stack is not running** — not a network
+or permission problem. Run `nself start` to resolve it.
+
+---
+
+## Panels
+
+### Service Health
+
+Displays all nSelf services (postgres, hasura, nginx, redis, etc.) with their
+current status: Running, Starting, Stopped, Error.
+
+Empty state: "No services running — run `nself start`."
+
+### Database Console
+
+Run arbitrary SQL against the nSelf Postgres database. Admin has full SQL
+access — no query-type restrictions.
+
+- Input validated: non-empty only (Zod)
+- Results displayed in a scrollable table
+- Row count and execution time shown
+
+### Backup Panel
+
+Create and list nSelf backups.
+
+- Backup name: alphanumeric, hyphens, underscores; max 50 chars
+- Each backup shows: name, date, type, size, status
+- Empty state: "No backups yet — create your first backup above."
+
+### Deployment UI
+
+Multi-environment deployment status and control.
+
+- Environment switcher: Local / Staging / Production
+- Deployment timeline with step-by-step status
+- Shows version and last-deployed timestamp per environment
+
+### SSL Panel
+
+Certificate status for all configured domains.
+
+- Status: Valid, Expiring soon, Expired, Missing
+- Shows expiry date and days remaining
+- Issuer displayed where available
+
+### GraphQL Playground
+
+Embedded Hasura GraphQL console (iframe).
+
+- Opens the Hasura console URL proxied through the admin
+- "Open in new tab" link available for full-screen use
+
+### Web Terminal
+
+Browser-based terminal for nSelf CLI commands.
+
+- Commands run via `/api/terminal/exec` (not a direct shell)
+- Enter key submits; exit code shown on failure
+- Output history persists for the browser session
+
+### Grafana Integration
+
+Embedded Grafana dashboard for nSelf metrics.
+
+- Shows system metrics: CPU, memory, request rates, error rates
+- "Open in new tab" for full Grafana experience
+
+### Plugin Config
+
+View and toggle all installed nSelf plugins.
+
+- Toggle enabled/disabled per plugin
+- Shows tier (free/paid) and description
+- Optimistic UI update on toggle
+
+---
+
+## Smoke Test Checklist
+
+Run these to verify admin works after a stack update:
+
+1. **SQL**: Open Database Console → type `SELECT 1;` → click Run → verify a result row appears.
+2. **Backup**: Open Backup Panel → enter a name → click Create backup → verify it appears in the list.
+3. **Health**: Open Service Health → verify running containers are listed with green status.
+4. **Grafana**: Open Grafana Panel → verify the iframe loads with metrics data.
+
+---
+
+## Troubleshooting
+
+| Problem | Likely cause | Fix |
+|---|---|---|
+| All panels show "offline" | nSelf stack not running | `nself start` |
+| Login overlay appears | Session expired (24h) | Re-enter admin password |
+| SQL returns an error | Invalid query | Check syntax; admin has full access so all queries are forwarded as-is |
+| Backup fails | Disk space | `df -h` on the host; free space or adjust retention |
+| Grafana iframe blank | Grafana service not healthy | `nself status grafana`; check logs |

+# Session Management
+
+The nSelf admin GUI uses a **24-hour password-based session** backed by
+LokiJS (in-process JSON store). This is a local-only tool; there is no
+network-accessible auth surface.
+
+---
+
+## Session Lifecycle
+
+1. **Login** — POST `/api/auth/login` with the admin password.
+   - Password is bcrypt-hashed and stored in the LokiJS session store.
+   - A session cookie (`nself-admin-session`) is set with `HttpOnly; SameSite=Strict`.
+   - Session TTL: **24 hours** from the time of login.
+
+2. **Session check** — every panel API call sends the session cookie.
+   - Server-side: LokiJS validates the session ID and checks `expiresAt`.
+   - Expired or missing session → `401 Unauthorized`.
+
+3. **Session expiry** — when the 24h TTL passes:
+   - The next API call returns `401`.
+   - The panel switches to the **auth-expired** AsyncScreen state.
+   - An **`AdminLoginOverlay`** appears over the panel content.
+   - The user enters their password; on success the session is renewed
+     and the panel re-fetches its data.
+
+4. **Session refresh** — available via POST `/api/auth/refresh` while the
+   session is still valid (within the 24h window).
+   - The admin warns when 2 hours remain (optional banner).
+   - Auto-refresh fires at the 20-hour mark (4 hours before expiry).
+
+---
+
+## Security Notes
+
+- Session validation is **server-side only** (LokiJS). Client-side state
+  (React context, localStorage, cookies) cannot bypass the server check.
+- The `AdminLoginOverlay` renders when the server returns `401`; it is
+  not triggered by client-side timeout logic.
+- CSRF protection: all mutating requests require the `x-csrf-token` header
+  (value read from the `nself-csrf` cookie).
+- The admin is bound to `localhost:3021` and is never deployed publicly.
+
+---
+
+## Re-authentication Flow
+
+When a panel detects a `401` response:
+
+1. `sessionExpired` state is set to `true`.
+2. The `AsyncScreen` switches to the `auth-expired` state.
+3. `AdminLoginOverlay` renders over the panel.
+4. The user enters their password.
+5. `POST /api/auth/login` is called.
+6. On success: overlay closes, `sessionExpired` resets to `false`,
+   panel re-fetches its data.
+7. On failure: error message shown in the overlay input.
+
+---
+
+## Multi-User Support
+
+Multi-user admin access is planned for v1.2.0 and is **not** in scope for
+the current version. The current model is single-admin, single-password.
+All sessions share the same credential.

+ *   - Empty state = no rows returned (query succeeded but 0 results)
+ *   - Error state = SQL execution failure
