v0.2.16

• Record decisions in production and fit a threshold from them. Client(..., recorder=JsonlRecorder(path)) writes one row per decision with the probabilities, the reported confidence, the route and the latency; record_outcome(path, id, {...}) attaches what actually turned out to be right; rows_from joins the two into exactly what fit_temperature and fit_conformal_quantile take. decide fit <file> <question> prints the fitted values plus what each threshold would have accepted and how often it was right, which is the table that says whether a gate is safe to turn on. Recording never fails a decision: a recorder that raises is ignored.
• decide fit also prints the range of confidence actually reported, since a threshold table of zeros usually means every threshold sits above what the backend reports.
