#eval_source ⇒ Object

Source to feed to the load-time evaluator. Defaults to mutated_source when no pre-eval transform was applied at generation time. Mutator::Base populates this with the neutralized version (top-level idempotency- violating calls replaced with ‘nil`) so the worker eval doesn’t re-run them. The neutralization Prism parse happens once at generation time, not per worker iteration.
