A Triage-and-Audit Resource for the 9,408 Undeciphered Classes of HUST-OBC, with 279 Verified Metadata Corrections

A triage-and-audit resource over all 9,408 undeciphered character classes of HUST-OBC. Each class is annotated with (i) its most shape-similar official glyph code and that code's official reading and status, from the Yinqi Wenyuan platform, and (ii) whether the authoritative Jiaguwenzi Gulin (Jitilin) compendium already contains a discussion entry for it. A construction-guaranteed identity mapping over the Y+H classes yields 279 verified metadata corrections — classes labelled undeciphered that already carry an official reading — each re-verified live against the platform API (279/279). The resource functions as a filtered target space that separates genuinely-unclaimed characters from already-discussed ones. All records are reproducible from public, login-free endpoints; no copyrighted scans or fonts are redistributed (only character codes, page identifiers, factual readings, and reproduction URLs). Files: triage_resource.csv/.json (9,408 rows), yh279_corrections.csv/.json (279 rows), data dictionaries, API cache, summary, and the deterministic builder script. This release also bundles the methods-paper preprint (methods_paper_preprint.pdf) and the Data Descriptor draft for a single citable code-and-data archive.
