Flagged for Jams, Cited for Staffing

A paper from the School of Continuous Improvement builds and deploys the Return-Chute Sentinel, a load-cell-and-break-beam sensor for the University Library's after-hours book-return chute, cutting fault-detection latency from an hour-bound manual round to a couple of minutes and reducing night staff's walk-through rounds by three-quarters across a fourteen-week deployment, with an ablation finding its break-beam channel makes little difference to detection accuracy. The paper separately traces how the sensor's alert log, which counts only mechanical chute events, came to be cited by Facilities' after-hours staffing review as evidence of sustained patron demand for a staffed desk, a use the instrument was never built to support.
