Execution API

Layer 4: Extend Framework

The Execution API exposes evaluators, initializers, the asynchronous evaluation scheduler, and runtime registration mechanisms. Runner is an internal implementation and is not included in this public listing.

saealib.execution.AsyncEvaluationScheduler	Coordinate asynchronous requests and serialized state mutation.
saealib.execution.PollResult	The state and progress observed by one asynchronous poll.
saealib.execution.RuntimeFactory	Factory protocol for runtimes selected by a provider registry.
saealib.execution.RuntimeRegistration	One explicit runtime selection rule.
saealib.execution.RuntimeRegistry	Runtime selection errors on conflict; compiler rules do not select a runtime.
saealib.execution.create_runtime	Create a runtime through the replaceable default provider registry.
saealib.execution.default_runtime_registry	Runtime selection errors on conflict; compiler rules do not select a runtime.

See Evaluation and Initialization for details about evaluators, evaluation Requests, and initializers.
