title: "Re-prepare PVF artifacts only if needed"

doc:
  - audience: Node Dev
    description: |
      When a change in the executor environment parameters can not affect the prepared artifact,
      it is preserved without recompilation and used for future executions. That mitigates
      situations where every unrelated executor parameter change resulted in re-preparing every
      artifact on every validator, causing a significant finality lag.
