The supplement survives offshore

Claim (verbatim)

The supplement survives offshore. Uicheon's Kyojang — his printed canon of East Asian scholastic commentaries — was almost wholly lost in Korea, and the conjecture is that its survival is conditional on a specific carrier: scripture is maintained by state canon-projects, but commentary is maintained by classrooms, and when Koryo's scholastic schools contracted, the classrooms still hungry for this literature were Japanese (the Nara-Kyoto Kegon, Hosso, and Tendai lineages, which imported Kyojang prints within decades). Survival of a Kyojang title should therefore depend not on its content or length but on whether it acquired a Japanese pedagogical node before the Korean constituency collapsed.

Prediction clause (verbatim)

Take the titles in Uicheon's own catalogue of the collection. Primary clause (verdict follows it): among titles extant today in any form, at least 70 percent have their earliest extant witness in a Japanese collection or a Japanese-lineage copy. Secondary: the minority extant only in Korea clusters in texts that were also recarved in later Korean supplementary block projects — a second, state carrier — rather than distributing randomly across the catalogue.

Kill-dataset (verbatim)

Kill: Uicheon's Sinp'yon chejong kyojang ch'ongnok, digitized in CBETA (T 2184), crossed with the published censuses of extant Kyojang prints and copies in Japanese temple collections (the Kozanji and Todaiji catalogues).

Novelty / leakage triage

provisional — model-triaged, shepherd review pending

A provisional first pass authored by the model (Opus), not yet confirmed by the shepherd. It carries the same dated-search requirements as an authoritative verdict but is excluded from every headline figure and cannot underwrite a prediction until a shepherd confirms it. Provisional reading: Leaked (already exists in the literature).

The item's surprising connection -- that Uicheon's Kyojang (his printed canon of East Asian scholastic commentaries) survived not in Korea but through a Japanese carrier -- is already the documented picture. The Koryo blocks and the supplement gathered by Uicheon were destroyed in the 1231-32 Mongol invasion, and the specialist literature records that the sokjanggyeong was imported to Japan in quantity in the early 12th century by monks of Kofuku-ji, Todai-ji and Ninna-ji, and that today only a handful of its texts survive, in Japan. The verdict follows the item's primary clause (>=70% of extant titles with their earliest witness in a Japanese collection), and that clause restates the documented survival-through-Japan pattern. Fresh and unrun is only the exact proportion and the classroom-carrier timing mechanism -- not the connection.
