crab errorsCopy the complete CRAB-E#### value from the original failure. The lookup
explains the stable error category and suggested response, while the original

responses. Looking up a code is read-only and does not retry or repair the
failed operation. Use --json when an incident tool needs the explanation in a
structured envelope.
