Under "Non-offenses": there are eight marks across three categories. The first two flip the offenses to clarify non-offenses (the Commentary on the Prātimokṣa also has: conforming to the measure, assigned by the saṃgha, and marking the ground according to the Dharma, which together with the above make five); the four including a stūpa are because they are not exclusively for oneself; the two including grass huts are because they do not exceed the measure.
