harness_service.rs

//! Versioned, language-neutral service over persisted harness sessions.
//!
//! The service is transport-agnostic: [`HarnessSessionService::handle`] accepts
//! one JSON-RPC value and [`HarnessSessionService::poll`] produces subscription
//! notifications. The CLI exposes those primitives as NDJSON over stdio.
