MuxServerLoom
Parameters
accept source for incoming client connections.
this server's own PeerId.
required authorization policy for per-room membership. Invoked on the first inbound frame per (connection, room) pair; a false return structurally excludes the connection from that room. Use RoomAuthorizer.AllowAll for open-access servers. Required (no default) per the "optional ≠ tuning" rule — absent it the gate would be silently disabled.
coroutine context for mesh-seam link loops. Defaults to the interceptor from scope so virtual-time tests share the test dispatcher automatically.
seeded Random for mesh-seam nonce generation.
ceiling on a single accepted connection's handshake+admit; a connection that connects but never completes its MeshHello handshake is abandoned and closed after this, so it can never wedge the accept loop. Each accepted connection is admitted concurrently in its own child coroutine (all shared state is lock-guarded), so a slow handshake never starves later connections either.
