Configure the default WSS endpoint and ISRG Root X2 trust anchor, preserve device authentication, enforce TLS and WebSocket handshake validation, and handle partial I/O and connection cleanup. Add host tests, server probes, package verification and integration documentation. Backend 443 /ws still returns HTTP 404; on-device validation remains pending.
