Annotation Interface SagaStep

@Documented @Retention(RUNTIME) @Target(METHOD) public @interface SagaStep
Declares a method as a saga step in an annotation-derived descriptor.

A trusted managed saga factory persists intent before the callback and preserves its external idempotency key across takeover. Non-idempotent uncertainty requires reconciliation.
