classdef tReport < matlab.unittest.TestCase
    %TREPORT Tests for tdcs_glm / tdcs_report (Task 4: entry point + report).
    %
    %   MATLAB R2025b + Statistics and Machine Learning Toolbox IS licensed
    %   in this environment, so this suite is actually run. It does not
    %   re-check golden values (tModels already does that); it checks the
    %   wiring: tdcs_glm(scenario) runs end-to-end without error and writes
    %   results/<scenario>.txt, and the otherwise-branch errors on an
    %   unrecognized scenario name.
