Helper Methods

The following helper methods are declared via @method and must be implemented by every runtime. The schema declares the logical protocol contract; each runtime maps async-capable methods to idiomatic sync/async shapes for that language.

Name	Signature	Runtime shape	Description
appendSession	appendSession(sessionEvent: SessionEvent) -> boolean	sync, atomic	Append a session event to a durable replay journal
appendTurn	appendTurn(turnEvent: TurnEvent) -> boolean	sync, atomic	Append a turn event to a durable replay journal
close	close(summary: SessionSummary?) -> boolean	sync, atomic	Finalize the journal with an optional session summary
