Validate Idempotent Linux Task Runner | Dataford Interview Questions

Given a list of Linux automation task results, implement a function that determines whether the automation run is safe and repeatable. Each task is represented as a dictionary with keys name, changed, rc, and check_rc, where changed is a boolean indicating whether the task modified the system, rc is the normal execution return code, and check_rc is the dry-run return code. Return True if every task succeeded in both modes and at least one task is idempotent, meaning its dry-run and normal execution agree on whether a change is needed; otherwise return False.

Constraints

1 <= len(tasks) <= 10^4
Each task contains keys: name, changed, rc, check_rc
rc and check_rc are integers in the range [-255, 255]
