//! The UDS wire protocol (spec §4.3): newline-delimited JSON, one request
//! and one response per line. The check response carries the SAME uniform
//! result JSON as the cold path (§8.3) — the daemon is a transport, never
//! a second brain. `deny_unknown_fields` on ingest (charter N2); versioned
//! so a stale daemon and a newer shim fail loudly, not weirdly.
