How does Kotlin handle deterministic debugging in asynchronous systems?

Deterministic debugging is achieved through structured concurrency and explicit state modeling.

Async systems are hard to debug because execution order is non-deterministic. Kotlin reduces this unpredictability using structured concurrency, ensuring parent-child relationships define lifecycle and cancellation. However, true determinism requires explicit state modeling, logging correlation IDs, and replayable event systems. Without these, debugging becomes probabilistic.
