Module host_state 

Host session state the observe hook records for the rest of the engine.

The observe hook (hook_handlers::observe) learns which model and which transcript the host is running from its payloads and persists them in the data dir; the context radar, ledger, telemetry and conversation reader load them back. Both directions live here so the file formats have one owner and engine readers do not depend on the hook layer.

persist_detected_model

Persist the host’s current model (skips background models) to detected_model.json.
