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)
Tibetan Buddhist ritual is one of the most heavily textualized liturgical cultures on earth - the cho-ga (ritual manuals) for every rite exist in profusion, and the Buddhist Digital Resource Center (BDRC) has digitized the corpus at scale. But the melodic dimension of that liturgy, the dbyangs (the long, shaped melismatic chant), was notated only sparingly and separately, in the specialist contour-scores called dbyangs-yig (dbyangs yig) - the "sound-writing" of curving contour lines studied by Ter Ellingson. The claim is a write-down asymmetry: within a liturgical culture that committed its words to writing almost totally, the melody was overwhelmingly left to oral, lineage-bound transmission and only rarely scored. So in the digitized corpus, texts that carry or are dbyangs-yig should be a vanishing fraction of ritual texts - and, because dbyangs-yig are monastery- and tradition-specific, the notated melodic corpus should be a thin, uneven scatter rather than systematic coverage of the performed chant. The mechanism is that melody was the master's body-knowledge, transmitted mouth-to-ear, while the words were the transmissible dharma. Prediction restated: dbyangs-yig form well under one percent of the ritual-text corpus, so the Tibetan case is an extreme instance of melody under-written relative to text, and most performed dbyangs has no surviving score at all.
Prediction clause (verbatim)
Prediction: querying the BDRC (Buddhist Digital Resource Center) corpus, works identifiable as dbyangs-yig (melodic contour-notation) will number under one percent of the works identifiable as ritual or liturgical texts (cho-ga and related), and will cluster by specific monastery or tradition rather than covering the performed chant repertoire uniformly. Primary clause: dbyangs-yig are under one percent of ritual texts. Disambiguation: identification is by genre designation or title-marker (dbyangs yig / dbyangs) and catalogue metadata, not by full-content inspection of every text. Coverage guard: if the ritual-text baseline returned is fewer than 1,000 works, the test voids for insufficient corpus.
Kill-dataset (verbatim)
Kill (not yet built): the BDRC (Buddhist Digital Resource Center) catalogue, counting works tagged or titled as dbyangs-yig against the baseline of ritual and liturgical (cho-ga) works, with Ter Ellingson's dbyangs-yig inventory ("The Mandala of Sound," 1979) as the cross-check on what counts as a melodic score.
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.
Provenance
Run: Fresh agent generation · model: claude-fable-5
Fresh blind generation by claude-fable-5, 2026-07-17, Asian musical-transmission wave (music_liturgy section) against real corpora of notated and orally-fixed Asian music: qin tablature (Qinqu jicheng, Zha Fuxi's Cunjian guqin qupu jilan, Shenqi mipu 1425, the Jieshi diao Youlan), the Dunhuang pipa manuscript (Pelliot chinois 3808) vs the Jiaofang ji, gagaku/togaku (Picken-Marett Music from the Tang Court; Meiji senteifu) and the medieval Japanese tablature encyclopedias (Jinchi yoroku, Sango yoroku), Korea's aak and dangak (Akhak gwebeom 1493, Goryeosa Akji, Munmyo jeryeak), Vietnamese nha nhac, the Sanskrit theory chain (Natyasastra/Dattila/Matanga's Brhaddeshi/Sarngadeva's Sangitaratnakara via GRETIL-SARIT), Samavedic gana fixity (Wayne Howard; Staal's Nambudiri documentation), Tibetan dbyangs-yig (BDRC; Ellingson), Javanese gamelan notation-absence (kepatihan; Serat Centhini; Wedhapradangga), Uyghur On ikki muqam (Turdi Akhun), and Tamil Tevaram pan. Every kill names a real open corpus/edition and a countable operation (format/attestation censuses, title-matching, citation-overshoot, survival inversions, name-survival and disagreement rates) with thresholds far from 1 and coverage guards; 'Kill (not yet built)' flags items whose decisive dataset must still be assembled. HARD EXCLUSION honored: zero Latin/Western-liturgy items (owned by the concurrent music-liturgy wave). Disjoint from the 2026-07-08 w09 music/liturgy wave (Latin/Islamicate/Armenian chant) and from the East Asia ctext/w04 text-culture waves. Drops recorded in the run report: an Indian theory-chain named-lost-predecessor item steered away from Kohala (owned by breadth_india_w2 ord 6) and from the rasa-trio doxography (sanskrit_gretil ord 7); the Samavedic item kept to gana/stobha fixity, disjoint from the sakha-geography item (breadth_india ord 10); the gamelan item kept to notation-absence, disjoint from the Yogyakarta-1812 library item (breadth_seasia_w2 ord 5); Tevaram used as pan modal-loss, disjoint from the Tamil witness-count and Tamil icai-treatise items (breadth_india_w2 ord 17; breadth_india ord 17).
Novelty / leakage triage
anticipated in the literature — this exact test has never been run
Ellingson's dissertation and Asian Music article are the prior art: they establish that dbyangs-yig are a specialized, monastery- and lineage-bound genre, rare relative to the mass of liturgical texts, and they inventory the known examples - but this conjecture's instrument is a BDRC catalogue census, and no one has run genre-tagged counts over the digitized corpus or stated a percentage, so the under-one-percent clause and the clustering claim are unmeasured. Adjacent rather than novel_unlocated because the qualitative rarity and the cross-check inventory are in print.
