Replication package for "When Does LLM Test Repair Destroy Bug-Revealing Tests? A Cost-Accounted Study on Real Repository Defects"

It contains the study protocol with its dated amendments, the Docker-free execution harness, every LLM request and response with provider-reported cost, every recorded test version with its outcomes on the buggy and the fixed program version, the test-execution logs, the model-based audit samples, the official-harness cross-check, and the scripts that regenerate every table, figure and in-text number of the paper.
