This does the heavy lifting when you're porting existing orchestration code from Temporal, Inngest, Trigger.dev, or AWS Step Functions into the Workflow SDK. It knows how to map Activities to steps, Signals to hooks or webhooks, wait-for-event patterns to the right resume surface, and state machines to workflow functions. The routing logic is strict: it picks between internal hooks with deterministic tokens, auto-acknowledged webhooks, or manual-response webhooks based on what your prompt actually requires, and it fails the draft if you mix primitives that don't belong together. Worth using when you have working orchestration elsewhere and need a clean migration path that respects idempotency, streaming, retries, and the use-workflow versus use-step boundary.
