We present a lightweight provenance layer for RFsignal classifiers that records each label update as a verifiabletrail: old/new labels, confidences, timestamps, and operatoror system update rationale. Anchored in a production-grademethod (update_signal_classification) that appends toa classification_history, the system enables courtroomgrade telemetry by mapping directly to the electronic-evidencechecklist in Lorraine v. Markel and meeting reliability expectations under … Continue reading Chain-of-Thought for Classifiers: Evidentiary Trails in RF Operations
