The proxy answered every routed name to any request carrying it, so an
internal-only route would have been public under its internal name. Each
membership now carries what its module receives, from the same
composition as its received file, and every machine's private-network
address, the list the packet filter's "from the mesh" is. The proxy
follows its membership, serves internal names only to those machines and
itself, and keeps the file until the bus has spoken (novox/hq ADR 0167,
issue 191).
Since ADR 0138 an endpoint that reaches only the private network gets an
internal-name and no name, and the proxy skipped it as naming nothing, so
every internal-only module was unreachable by name (novox/hq issue 191).
