Interface: UnsafeRandomSource

workflow.UnsafeRandomSource

A nondeterministic random source: every draw is fresh entropy, not derived from the Workflow seed and not replay-stable. Only safe in read-only Query handlers and update validators; using it on the main Workflow path causes non-determinism errors.

This API may be removed or changed in the future.
