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
append	append(event: EngineEvent) -> void	async-capable	Append one semantic engine event durably
appendWithCheckpoint	appendWithCheckpoint(events: EngineEvent[], checkpoint: EngineCheckpoint) -> void	async-capable, atomic	Atomically append semantic engine events and persist the checkpoint that reflects them
