Criteria::fromQuery documented itself as the point where the query string is validated, and raised eight of the nine failures a malformed request can produce. The cursor was the exception: Token defers the decode, so CursorIsInvalid surfaced from SeekClause while the seek was being built, long past the try every consumer wraps fromQuery in. Every consumer therefore answered 500 to a tampered cursor instead of 422. Decoding at the boundary completes the contract and fixes them with no change on their side.
