The melody mint closes
Status is derived only from the shepherd-authored triage/prediction data above -- community submissions and claims are a separate overlay and can never change it (see the participation panel below).
Claim (verbatim)
A Byzantine kanon is sung to model stanzas, heirmoi, which fix its meter and melody; early hymnographers composed new heirmoi freely. The conjecture is that heirmos creation shut down like a mint closing: after about 900 the repertory of models was effectively frozen, and later kanon writers — however prolific — overwhelmingly set their words to existing heirmoi rather than coining new ones. The mechanism is notational and institutional: once heirmologia (the model-books) were compiled and copied as authoritative collections, a new melody had no channel into the books that choirs actually sang from. If it holds, Byzantine hymnography's creativity migrated from music into text on a datable schedule, and the heirmologion is the instrument that ended melodic composition while liturgical poetry boomed.
Prediction clause (verbatim)
Primary clause: the share of kanones set to newly composed heirmoi falls from a majority among authors active before 800 to under 10% among authors active after 900. Secondary: post-900 new heirmoi that do exist cluster in peripheral traditions (Italo-Greek, Palestinian) rather than Constantinople.
Kill-dataset (verbatim)
Eustratiades' catalogue of the Heirmologion with the apparatus of Analecta Hymnica Graeca and Follieri's Initia hymnorum ecclesiae graecae.

Novelty / leakage triage
anticipated in the literature — this exact test has never been run
Handbooks state that creative hymnographic composition ended and that the tenth-century heirmologion fixed a repertory of over a thousand model stanzas, but the mint-closure schedule — share of newly coined heirmoi falling below 10% after 900, with peripheral exceptions — is un-run.
