This directory ships reproducible software-validation scripts and design metadata. Executed evidence must be written outside the installed package/source tree. None of these simulations establishes construct validity of gaze, pupil, response-time, or process measures.
The main entry point is scripts/run-all-validation-evidence.R. Use profile local for a compact deterministic run and full for the larger predeclared evidence programme. Exact IRT recovery is executed only when mirt is available; otherwise it is explicitly gated and no substitute estimator is used.
Any scripts or data that you put into this service are public.
Add the following code to your website.
