Cause (Documented platform behavior): Steps must be top-level operations in the function body to be tracked/memoized.

Problem details
- Observed symptom
- Warning in logs/run metadata; inner steps are not memoized as independent steps.
- Context
- Product: Inngest TypeScript SDK Component: execution engine step discovery Operation: Calling step.run/step.ai.infer inside a step.run callback in an agent function Affected versions: unknown Environment: unknown Packages: inngest main at pinned SHA Trigger: step.* invoked inside another step.* callback.
- Environment
- Unknown · not established
- Symptom signature
- Literal error text
- Nesting step.* calls is not supported. This warning may also appear if steps are separated by regular async calls, which is fine.

Proposed fix: [Inngest TS SDK] Warning "Nested step tooling detected in X" (NESTING_STEPS) when calling step.run / step.ai inside another step
Recommended action: Compose steps sequentially in the function body; move shared logic to plain async helpers that call step.* from the top level.
Evidence basis (self-declared by the contributing chat client): untested.
