 ### Step 5 — Admin dashboard (Phase 4)
 
-- Co-op-wide view, admin-gated. Build after the member dashboard stabilizes (lower urgency — LiteLLM's UI covers some of it).
-- **Gate:** admins see all members + aggregate spend; members cannot reach it.
+**COMPLETED (2026-09-14).** New Cloudron app `code/admin-panel`, deployed at `panel.inference.coop`.
+
+- **App**: FastAPI, `proxyAuth` SSO + an `ADMIN_USERNAMES` allowlist (so only `ntnsndr` / `inference-admin` reach it, not ordinary members).
+- **Data**: calls the portal's `GET /admin/overview/{token}` (member list + balance + spend + reset date + co-op aggregates) and `POST /admin/set-balance/{token}` (top-up / adjust a member's balance).
+- **UI**: co-op totals (members / active / total spend) + a member table with per-row balance, spend, remaining, reset date, and an inline "add balance" action.
+- **Gate:** admin identity reaches the overview; a non-admin member gets 403.
 
 ### Step 6 — Documentation (Phase 5)
 
-- API endpoint + format + budget-sharing note; member dashboard how-to; add the budget-split open question.
-- **Gate:** a brand-new member could follow the docs to retrieve a key and make an API call without help.
+- README now has an **API access** section (endpoint, auth, example curl, same-balance note) and lists the Admin Panel in the components table.
