Simulated for package validation, inspired by Eckes & Jin (2021):
- Study 1 design target: 307 examinees, 18 raters, 3 criteria, 4-category scale
- Study 2 design target: 206 examinees, 12 raters, 9 criteria, 4-category scale

Notes:
- *_sim.csv files are baseline synthetic datasets.
- *_itercal_sim.csv files are iterative-calibrated synthetic datasets tuned to
  match target score distribution/fit/reliability profiles.

These are synthetic datasets (not original TestDaF operational records).
