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
listCheckpoints	listCheckpoints(sessionId: string) -> Checkpoint[]	async-capable	List checkpoints for a session
load	load(sessionId: string, checkpointId: string) -> Checkpoint?	async-capable	Load a checkpoint by session and checkpoint identifier
save	save(checkpoint: Checkpoint) -> Checkpoint	async-capable, atomic	Persist a session checkpoint and return the stored checkpoint
