"""mumble — INSTALL overlay (Phase 1e HC3): assertion-only + additive, runs alongside the generic
install tier (which proves the mumble-web HTTP sidecar serves over Traefik — the readiness signal).

This overlay ADDS the assertion that mumble's actual purpose — the voice server — is up: the murmur
control channel accepts a TLS connection on the host-published 64738 right after install. (The full
protocol handshake + channel presence is exercised in the custom tier; here we assert the install
produced a listening voice server, not only a web UI.)
