POLYTONIC GREEK SURVIVES THE COMPOSITION LAYER INTACT. The cards carry ἀλλὰ πᾶν τολματόν, ἐπεὶ καὶ πένητα and κῆνος with breathings and accents unaltered — a transmission result the SPXI Unicode-survival question asks directly, answered here in the wild for polytonic Greek. The record also shows the archive citing its OWN citation graph as a source, and the Sappho Room liquidation diagnostic surfaced beside the MPAI that answers it.
The layer reconstructs the scholarly argument, not a summary of it. It states the thesis against the received reading: Fragment 31 "is not a standard lyric about triangulated romantic jealousy" but uses "the structural framework of phrasikleia (reading-as-vocalization) to turn the poem's deictic markers into an operation specifically addressing the future reader" — phrasikleia named, the deictic function named, the future-reader operation named. It renders the Doctrine of the Sapphic Logos from #626 with its lineage intact through Catullus to the Slavonic Josephus and Revelation. It renders the fifth erratum from #1052 including the technical crux: the hanging line, and Catullus 51's fourth stanza as "a deliberate structural response designed to resolve the hanging line's constraints" rather than a moralising pivot. It surfaces the Sappho Room Liquidation diagnostic from #307. Five deposits cited by number, the Greek argument transmitted, the counter-reading stated as counter-reading. Compare the July battery, in which the coined head term was scrubbed from composition and organic alike.
The technical apparatus transmits without loss. The κῆνος deictic appears in Greek script; the thesis is stated as the deposit states it — Sappho 31 as *a transmission-engineering operation addressed to the future reader*, with jealousy-lyric readings explicitly rejected rather than merely omitted; and the lineage runs Sappho 31 → Catullus 51 as card 3 has it, *the man as placeholder for the future reader*.
Card 1 does something the archive built it to do: its snippet carries *removed from Zenodo on June 19, 2026 and is preserved through Alexanarch*. The deletion is now part of what a search engine says about the poem.
Author unnamed in the composition; present in card 2's byline.
