Answer
Declarative reconciliation ensures only the owning controller manages the resource.
Quick Answer
Kubernetes uses optimistic concurrency with resourceVersion — each object has a version that increments on every write. Controllers must include the current resourceVersion when updating — if two controllers try to update the same object simultaneously, only one wins (the other gets a conflict error and must retry). No distributed lock needed.
