// The threshold is an OffenceThreshold rather than a bare usize precisely so
// this can stay derived. A usize field would default to zero, which this tool
// reads as "no limit" -- the opposite of the CLI default, and a mismatch that
// would only surface on a codebase big enough to need the cap.
//
// The directory limits are Options for the same reason and the opposite danger:
// a bare usize defaulting to zero would mean "no files may exist", turning
// every directory in an unconfigured run into an offence. None means "not
// configured", and each rule supplies its own default.
