errorless (adj)
Free from error, accurate, correct. Being complete of its kind and without defect or blemish.
Walk through enough architecture reviews and you start recognising a specific shape of failure. The system isn’t wrong. It’s too right. Every edge case has a handler. Every failure has a fallback. Every component is wrapped, secured, and isolated from everything else. The development cost is enormous. The operational cost is worse. And when the requirement changes, which it always does, nothing moves.
