Neumes for the Ark of the Covenant
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).
“Anticipated in print” means the direction of this claim already appears in scholarship, while this exact test has never been run — it records prior art, not proof; nothing here counts as supported or falsified until a registered resolution says so.
Claim (verbatim)
Gregorian chant became a quantitative field when its notation was databased: Cantus clusters hundreds of thousands of melodies by notated incipit, and notation density can be tracked over time. Ethiopian liturgical chant (zema) has its own indigenous notation — the mǝlǝkkǝt, interlinear signs credited to the sixteenth-century tradition of Saint Yared's heirs — preserved in antiphonary manuscripts now imaged in Beta maṣāḥǝft and vHMML, and studied almost entirely qualitatively. I conjecture that the Cantus toolkit transfers whole: mǝlǝkkǝt sign sequences behave like melodic incipits, so unsupervised clustering will recover the three canonical zema modes (gǝʽǝz, ǝzl, araray) from the signs alone, and dated manuscripts will show a measurable growth of the sign inventory after the Gondarine liturgical consolidation — the same notation-densification trajectory Latin neumes followed after the Carolingian reform. The mechanism is convergent: any memory-support notation under pressure of standardization accretes signs, because each disputed performance detail gets frozen into a new mark. If this holds, the second great neumatic tradition of the world becomes computable, and notation growth-curves become a cross-cultural clock for liturgical standardization.
Prediction clause (verbatim)
Unsupervised clustering of mǝlǝkkǝt sign sequences from imaged Ethiopian antiphonary manuscripts will assign chants to the three traditional modes in >= 70% agreement with the manuscripts' own rubrics (Cohen's kappa >= 0.55). Primary clause (the verdict follows it): the >= 70% mode-recovery agreement. Secondary clause: manuscripts dated after 1600 show a distinct-sign inventory at least 1.3 times that of pre-1600 manuscripts.
Kill-dataset (verbatim)
Imaged and catalogued Ethiopian antiphonary (Dǝggwa) manuscripts in Beta maṣāḥǝft and vHMML; kill is a statistical test (clustering agreement measured by kappa, plus inventory-size comparison).

Nobody has run this test. The kill-data is named above. If you can run it — or you know the paper that already settles it — claim the kill or submit the prior scholarship. Kills and prior scholarship are credited here, by name, as they come in.

Novelty / leakage triage
anticipated in the literature — this exact test has never been run
Computational analysis of Ethiopian Orthodox chant modes now exists (Zema Dataset; YeZema Silt mode classification, 2024), but it operates on audio pitch contours, not on mǝlǝkkǝt sign sequences in imaged Dǝggwa manuscripts, and no notation-sign clustering or sign-inventory growth analysis around the Gondarine consolidation was located.
