How does Kotlin ensure correctness in asynchronous distributed workflows?

Kotlin ensures correctness via structured concurrency, explicit state modeling, and idempotent workflow design.

Distributed workflows are inherently unreliable due to partial failures, retries, and network delays. Kotlin helps structure workflows using coroutines, but correctness depends on explicit design: idempotent operations, deterministic state transitions, and failure-aware models using sealed classes. Without these, async execution becomes non-deterministic and hard to debug.
