Some flavour of "git gc" after your reset is far more likely to crop up and ruin your day, that's true.
As long as you stay on the statistical beaten path (i.e. you're asking about Paris), you will probably be fine, indeed. Probably. Stochastic bugs are always the most fun anyway.
You definitely go about making “stochastic bugs” more reliable in a manner different from debugging software.
It’s more akin to industrial engineering. There is no such thing as a perfectly machined widget. So we come up with an acceptable range of tolerances and compute a process capability. Six sigma. 3.4 defects per million and then buy an insurance policy.
