Data and analysis materials for "Silent Substitution in LLM-Generated Constructed-Response Questions: Instructor-Released Specifications for Assessment-Target Fidelity"

This deposit contains the materials needed to inspect and reproduce the statistics reported in the manuscript and its Supplementary Material S1. It does not contain the source code of the AIM-QG generation pipeline, which is proprietary; the code and configuration hashes recorded in the campaign lock (Supplementary S1-B) identify the version that produced the archived runs. Copyrighted curriculum materials (textbook passages and lecture slides) are not redistributed; contracts refer to curriculum evidence by chunk identifier only. All generated tasks are in Vietnamese, the language of instruction. Contract and rule statements are in English. The folder structure and reproduction commands are described in README.md inside the archive.
