pub fn announce_addr(addr_file: &str, listener: &TcpListener) -> Result<()>Expand description
Announce a bound loopback listener’s address through addr_file — the
discovery handshake for the built-in test mocks (--internal-mock-llm,
--internal-mock-mcp-http): the harness passes a fresh path, waits for the
file to exist, then reads host:port from it. Written atomically (tmp +
rename) so a waiter never observes a half-written address.
