Notes on verification

Confirmed by NDL Search and independently corroborated by CiNii and a secondhand bookseller listing, all agreeing on page count and dimensions for the same ISBN/edition. [tier=silver indep_score=0.525 clusters=2 claim_tier=everyday | framework convergence=partial on Japanese standard bibliographic cataloging conventions (page count + physical size in cm), though NDL, CiNii, and the secondhand bookstore each independently catalog the physical book (upstreams: National Diet Library (NDL) catalog, CiNii (National Institute of Informatics), publisher (Seikyusha) provided metadata via JPRO) — publishers independent, evidence may not be | kind=empirical eligibility=high]
