Comments: 11 pages, 4 figures, 8 tables. v2: PACT renamed STRAL to avoid a naming collision. Substantially revised model selection, threshold calibration, and empirical evaluation, including AMiner, Wazuh/AIT-ADS, NAD-CD, Guard, detection turnover, acquisition comparisons, classifier transfer, and sensitivity analyses. Earlier BOTSv1 and focal-loss results remain in v1
