//! Helpers shared between `hive-ag3nt` (agent) and `hive-m1nd` (manager)
//! serve loops. Only pure functions with no wire-type dependency live here;
//! request/response-flavored helpers (`requeue_inflight`, `ack_turn`, etc.)
//! stay in each binary because they use different request enum variants.
