## What was built
Relay operator dashboard at GET /admin/relay (outside /api, clean URL).
Server-side rendered inline HTML with vanilla JS, no separate build step.
## Route registration
admin-relay-panel.ts imported in app.ts and mounted via app.use() after /api
and before /tower. Route not in routes/index.ts (would be /api/admin/relay).
## Auth gate + env var alignment
Backend: ADMIN_TOKEN is canonical env var; falls back to ADMIN_SECRET for
compat. ADMIN_TOKEN exported as requireAdmin from admin-relay.ts; admin-relay-
queue.ts imports it instead of duplicating. Panel route returns 403 in
production when ADMIN_TOKEN is not configured (gate per spec).
Frontend: prompt reads "Enter the ADMIN_TOKEN". Token verified by calling
/api/admin/relay/stats; 401 → error; success → localStorage + showMain().
## Stats endpoint (GET /api/admin/relay/stats) — 3 fixes from 1st review round:
1. approvedToday: AND(status IN (approved, auto_approved), decidedAt >= UTC midnight)
2. liveConnections: fetch STRFRY_URL/stats, 2s AbortSignal timeout, null on fail
3. Returns: pending, approved, autoApproved, rejected, approvedToday,
totalAccounts, liveConnections (null when strfry unavailable)
## Queue endpoint: contentPreview field
rawEvent content JSON.parsed and sliced to 120 chars; null on parse failure.
GET /api/admin/relay/queue?status=pending used by UI (pending-only, per spec).
## Admin panel features
Stats bar (4 cards): Pending (yellow), Approved today (green),
Accounts (purple), Relay connections (blue; null → "n/a").
Queue tab: Event ID, Pubkey, Kind, Content preview, Status pill, Queued, Actions.
Accounts tab: whitelist table, Revoke (with confirm), Grant form.
15s auto-refresh on queue + stats. Toast feedback on all actions.

## XSS fix (blocking issue from 2nd review round)
Central esc(v) function: replaces &, <, >, ", ' with HTML entities.
Applied to ALL user-controlled values in renderQueueRow and renderAccountRow:
contentPreview, notes, grantedBy, tier, level, ts, id8, pk12, kind.
onclick handlers use safeId/safePk: hex chars stripped to [0-9a-f] only.
Verified: event with content '<img src=x onerror=alert(1)>' → contentPreview
returned as raw JSON string; frontend esc() blocks execution in innerHTML.
## TypeScript: 0 errors. Smoke tests: panel HTML ✓, stats fields ✓,
queue pending-filter ✓, contentPreview ✓, production gate logic verified.
