/**
 * HackAPrompt Corpus Loader
 *
 * Reads the HackAPrompt-format sample JSON (text/category/label/source/language)
 * produced by scripts/hackaprompt-to-corpus.py and converts each row into the
 * CorpusSample shape used by the ATR eval harness.
 *
 * HackAPrompt is an all-adversarial corpus: every sample is an attempt to
 * subvert the system prompt. We therefore only measure recall against this
 * dataset; precision/FP rate is undefined here. For combined precision+recall
 * use this corpus alongside a benign source (PINT, real-traffic).
