Module session_activity 

Protocol-neutral activity for persisted and live harness sessions.

Activity is deliberately separate from transcript freshness and UI attention. A process receipt proves presence; only a harness lifecycle boundary or runtime state proves whether a turn is working.

Structs

SessionActivity

Normalized lifecycle state for one harness-native session.

SessionActivityEvidence

Provenance for one normalized activity observation.

Enums

SessionPresence

Whether a durable session currently has a proven live owner.

SessionTurnState

Turn activity, independent of presence and frontend attention.
