Korea Victimization-Risk Persona Benchmark (KVRB): survey-anchored synthetic personas with crime-prevention behavioral attributes

A survey-anchored synthetic-persona dataset and reproducibility package that augments NVIDIA Nemotron-Personas-Korea with six crime-prevention behavioral attributes (financial vulnerability, digital literacy, authority deference, social isolation, prior victimization, reporting propensity). Each attribute is sampled from a weighted Korean national-survey conditional, so attribute distributions match the source surveys by construction. The Route-B build adds shared-demographic conditioning (age x sex x education) and one observed within-survey joint (victimization x reporting, from KCVS), with all inter-attribute structure labeled as measured or assumed. Contents: construction and validation code (src/), aggregate survey anchor tables with provenance (config/anchors/), technical-validation outputs and figures (results/), methodology docs, and the data-descriptor manuscript draft. Not included: the 1,000,000-row enriched persona file (reproducible from the code + anchors) and the raw survey microdata (held under the source agencies' terms). Synthetic only: no real victims, suspects, or PII. See ETHICS.md for the dual-use statement.
