Data and code for "From attribute co-occurrence to cultural claims: A construct-validity audit of archaeological attribution networks using Peranakan Nyonya ceramics"

This reproducibility archive supports a construct-validity audit of archaeological attribution networks using 75 Peranakan Nyonya ceramic records, 52 canonical motif nodes, 332 binary object–motif edges, and 312 node-tradition judgments per coder. It contains the object-motif layer, canonical motif dictionary, coding protocol, completed pilot and main coding files, reliability and adjudication records, archived and construct-aligned analysis outputs, complete null outputs, and a portable fixed-margin Curveball reproduction script. The journal manuscript and submission figures are not included. Third-party museum images and source documents are not redistributed; stable links, identifiers, descriptions, and evidence references are supplied where permitted. Version 2 aligns the archive with the construct-validity analysis reported in the manuscript. It adds the complete 11,200-configuration attribution-layer simulation, designates JAMT_Construct_Validity_Analysis.xlsx as the authoritative analysis workbook, and isolates the earlier pre-audit network-analysis workbook in 99_SUPERSEDED for audit history only. The coding manual was frozen on 25 July 2026. The reported 80.5% rate is conditional on the fixed-network simulation design and is not a field-wide estimate.
