Description: Ongoing surveillance of item parameter drift for continuous
    testing programs and pre-equated item banks. Estimates item difficulty in
    rolling calibration windows, runs sequential cumulative sum (CUSUM)
    detection (Page, 1954, <doi:10.1093/biomet/41.1-2.100>; applied to testing
    by Veerkamp and Glas, 2000, <doi:10.3102/10769986025004373>) with
    change-point estimation, separates gradual drift from abrupt jumps,
    tunes alarm thresholds for a bank-wide false-alarm target by simulation
    on the program's own design, quantifies score and pass-rate impact, and
    records recommended actions in an audit log.
