Supporting data package for "A two-tier audit framework for reporting foil–lacquer integration on the Shosoin gold-and-silver hyōmon qin"

This dataset is the standalone public supporting data package for the manuscript "A two-tier audit framework for reporting foil–lacquer integration on the Shosoin gold-and-silver hyōmon qin". It contains the machine-readable Tier A observation ledger, A-layer and B-layer corpus TSV files, derived views aligned with Supplementary Tables S1–S4, validation and manifest-generation scripts, and audit metadata sidecars documenting source boundaries, value scope, comparator/count boundaries, prospective Tier B parameter metadata, and figure-rights/caption metadata. Where protected Shosoin image handling is relevant, the package records crop-only/no-overlay metadata aligned with the Shosoin Office image-use guidance; it does not include protected Shosoin source images or derivative image files. The package supports traceable reporting and checking of the manuscript evidence ledger; it does not report completed Tier B measurements, identify binder chemistry, prove a finishing process, or adjudicate provenance, age, authenticity, attribution, or forgery.
