Closed-domain CRAG evaluation: code, prompts, queries, and per-query scores

Code, prompts, synthetic queries, per-query scores, and statistics for the article "Corrective Retrieval-Augmented Generation Adaptation in Closed Domains for Development of Intelligent Human Resource Management Systems" (Discover Artificial Intelligence, under review). The record reproduces the reported statistics without any handbook text: text-bearing files are replaced by same-structure stand-ins, and every context is identified by chunk, strips, and SHA-256 hash, so that it can be rebuilt from a licensed PDF of Armstrong's Handbook of Human Resource Management Practice (16th edition). Generated answers, reference answers, statements, and judge text contain handbook excerpts and are in a companion restricted record.
