Executed materials for the clinic-level execution under Amendment N1 to Paper 04 on CDC National ART Surveillance System (NASS) public datasets. This deposit contains the executed results report, harmonization codebook, data lock file (2026-10-24), analysis code, verdict files, bootstrap interval results and run log, and the panel-level result tables panel.csv and m2_inputs.csv. The panel tables carry opaque clinic identifiers only, with no clinic names, consistent with reporting M2 outlier clinics in aggregate only.
