runtime.non_serializable_payload

What it checks

Crux emits this finding for obvious non-JSON values passed across durable runtime boundaries.

Why it matters

Runtime payloads are persisted and replayed as JSON. Functions, Maps, Sets, and class instances cannot be delivered portably.

How to fix

Pass plain JSON data, or store complex values elsewhere and pass an id or URL reference.

When to suppress

Suppress only when a type-level or runtime serializer guarantees a JSON-compatible value.
