The book we quote more of than it still contains
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)
Matanga's Brhaddeshi (roughly sixth to eighth century) is the hinge text of Indian music theory - the work that first treats the desi (regional) ragas the Natyasastra had ignored, and the source that everyone after leans on. But it does not survive whole. The printed Brhaddeshi (Trivandrum Sanskrit Series 94, 1928, and the later IGNCA edition) is acephalous and lacunose, breaking off and lacking stretches its own later readers clearly still had. That gap is measurable, because Matanga's afterlife is a citation record: Sarngadeva's Sangitaratnakara and its commentaries (Kallinatha's Kalanidhi, Simhabhupala's Sudhakara) quote and paraphrase Matanga by name. When those quotations name doctrines and passages that have no counterpart in the surviving Brhaddeshi text, they measure the missing portion directly - citations that overshoot the extant work are a yardstick laid against a hole. The mechanism is ordinary manuscript attrition falling on a text kept alive mainly by being quoted rather than recopied whole. Prediction restated: a substantial share of the Matanga material quoted or attributed by the later theory-chain finds no home in the surviving Brhaddeshi, so that the citation record itself proves the printed text is a fraction of what Matanga wrote.
Prediction clause (verbatim)
Prediction: collating every by-name citation, quotation, and doctrine attributed to Matanga in the Sangitaratnakara with Kallinatha's and Simhabhupala's commentaries against the surviving text of the Brhaddeshi, at least a quarter of the distinct Matanga-attributed items will have no locatable counterpart in the extant Brhaddeshi. Primary clause: unlocatable Matanga citations are at least 25 percent of distinct citations. Disambiguation: an item counts as "unlocatable" only after checking both printed recensions (Trivandrum and IGNCA), and a paraphrase counts as unlocatable if the doctrine is absent, not merely differently worded. Coverage guard: if fewer than 30 distinct by-name Matanga citations can be assembled, the test voids.
Kill-dataset (verbatim)
Kill (not yet built): a Matanga-citation census assembled from the Sangitaratnakara with the Kalanidhi (Kallinatha) and Sudhakara (Simhabhupala) commentaries (Adyar Library edition), collated against the surviving Brhaddeshi (Trivandrum Sanskrit Series 94; IGNCA edition) - locate or fail to locate each Matanga citation in the extant text.

How this item is catalogued
Catalogue tags are curatorial metadata that make the conjecture findable. They are not findings, not a novelty verdict, and naming a source family is not a promise that the data exist or are accessible. Each dimension below says whether it was assigned, reviewed with none applying, uncertain, or not yet reviewed, and who recorded it.

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
That the transmitted Brhaddesi is mutilated, and that later theorists quote Matanga beyond it, is stated in the editions themselves - the Trivandrum editio princeps prints a corrupt and incomplete transmission, and Prem Lata Sharma's IGNCA introduction discusses the state of the text against the later citation record - while the Adyar Sangitaratnakara with Kallinatha and Simhabhupala supplies the citation corpus; but no one has collated the by-name Matanga citations against the extant text and printed an unlocatable share, so the 25-percent clause is un-run philological accounting. Minor caution: the losses are usually described as lacunae and a broken-off end; 'acephalous' should be verified against the editions before resolution.
