Dependent origination and the living arahat

In the 12 *nidānas* or 12 links of dependent origination , it's clear that the arahat has overcome craving, clinging and ignorance. Craving (*tanha*), clinging (*upādāna*) and ignorance (*avijjā*) have completely ceased for the living arahat. Question: However, for a living arahat, what happens to the *nidānas* of mental formations (*saṅkhāra*), consciousness (*viññāṇa*), name-and-form (*nāmarūpa*), sixfold sense base (*saḷāyatana*), contact (*phassa*), feeling (*vedanā*), becoming (*bhava*) and birth (*jāti*)? I understand that there are different interpretations to the standard model of dependent origination, including the across-three-lives interpretation (traditional Theravada), mind-moment interpretation (Theravada Abhidhamma), birth-as-arising-of-self-view interpretation (Buddhadasa?) and the impressions (sanskaras) plus naming-and-forming interpretation (Mahayana). Answers to this question are welcomed from all the different interpretations.
