As artificial intelligence progressively automates the learner relationship in online distance education, institutions face a question satisfaction metrics are not designed to answer: which functions can productively be served by AI, and which require recognisably human presence to honour what the institution constitutively owes its learners? This paper introduces Educational Relational Obligation (EduRO) — derived from Ọ̀nyèàyánà, an original Igbo philosophical principle meaning thou shalt not abandon thy relation, recovered from the proper name Ọ̀nyèàyánànwànnèyà. Three claims are advanced: AI can productively serve the KNOW and DO dimensions of institutional obligation; the FEEL and OUGHT dimensions constitute the spine of the learner relationship whose progressive automation erodes what makes an institution genuinely educational; and relational obligations intensify during difficulty. The paper is a contribution of Constructive Decolonisation: a scholarly programme, underpinned by African philosophical resources, for generating original governance instruments from non-Western traditions and contributing them to global educational discourse on their own terms.
