We present a lightweight provenance layer for RF
signal classifiers that records each label update as a verifiable
trail: old/new labels, confidences, timestamps, and operator
or system update rationale. Anchored in a production-grade
method (update_signal_classification) that appends to
a classification_history, the system enables courtroomgrade telemetry by mapping directly to the electronic-evidence
checklist in Lorraine v. Markel and meeting reliability expectations under Daubert and Kumho Tire. We contribute: (1) a
schema and pipeline for provenance-safe RF ops; (2) reproducible
scripts that transform real classification_history logs
into figures and tables; (3) a press-once build that emits a citable
PDF.
