why seated · Pessoa is the third term and the only one of the three with documented ground truth: the letter to Adolfo Casais Monteiro of 13 January 1935 attributes the heteronyms, so the grouping is known rather than inferred. That makes this corpus the positive control for any instrument claiming to detect designed differentiation, and nothing measured on Plato and Aristotle means anything until it has been calibrated here first.
