Not critical — those app proxy paths were already confirmed through other probes. The full attack surface analysis is complete above.

**Summary of critical findings:**

1. **Zero authentication on the entire RPC API** — every method callable by anyone on the network
2. **Arbitrary container image execution** — `package.install` pulls and runs any Docker image
3. **Cryptographic key abuse** — `node.signChallenge` signs arbitrary data without auth (confirmed with live signature)
4. **FileBrowser full access via default credentials** — `admin/admin` confirmed working with admin JWT
5. **Unauthenticated Claude API proxy** — free API usage at owner's expense (confirmed)
6. **P2P message injection** — spoofed messages already present in the message store
7. **CORS wildcard** on all endpoints enables drive-by attacks from any website
8. **Backend runs as root** with dev mode enabled in production

The most urgent remediation is wiring authentication middleware into the `core/archipelago` handler — the session infrastructure exists in `core/startos/` but is **not connected** to the active backend's request pipeline.
