Sappho Fragment 147 Is Remembrance; Fragment 31 Supplies the Seat (EA-MPAI-SAPPHO-147-01) is the reverse metadata packet in a registered pair by Lee Sharks, deposited 28 September 2026. Following the architecture of EA-MPAI-TOS-01, it takes the node AI compositions answer from — Sappho's Fragment 147, "someone, I say, will remember us, even in another time" — as its grammatical subject and states it at full strength: its text and transmission by Dio Chrysostom, the remembrance reading, André Lardinois's reperformance reading, and the popular reading in which the reader becomes the "someone". It then supplies the positive relation: 147 gives the horizon under which the future-reader reading of Fragment 31 becomes possible; 31 supplies a mechanism 147 does not contain. It audits three Google AI Overview compositions at 'sappho future reader' in which 147 answered, carried or led the question about 31, and is scored with its pair against a frozen failure vector.
