EA-CORPORA-01/06 seats Longinus's De Sublimitate entire in the archive's corpus program, fetched commit-pinned from Perseus (tlg0560, W. Rhys Roberts's edition over a public-domain base) and normalized to 185 chapter-and-section ref-lines. Its verification is the tradition's jewel: at Subl 10.2 the seated text carries Sappho fragment 31 whole, from φαίνεταί μοι κῆνος ἴσος θέοισιν through γλῶσσα ἔαγε to the hanging line — the fragment standing inside its unique ancient carrier on checksummed text, at exactly the quotation-joint where the erratum sequence locates the treatise's own performance of the operation it quotes. Sixth seat under EA-OMEGA-BUILD-01.
