💖 DESCRIPTION 💖

so this routine sets the high watermark as the number of outstanding XRIs — but (and this is the important part, don't skip it) it makes sure the new value lands between xri_limit/2 and xri_limit. no cap. it will not let the number escape that range. it's giving responsible. it's giving boundaries. we love to see it 👑
