Smart-meter fault detection under false-alarm budgets
A re-benchmark of fault detection on public 1 Hz ESP32 + PZEM-004T metering data (three stations, 1.8 million samples). The benchmark's own event-F1 protocol turned out to be degenerate — an always-on detector scores a perfect 100 — so I replaced it with a false-alarm-budgeted, leakage-safe protocol. Scale-invariant features nearly doubled AUPRC; transfer to an unseen station remained the binding constraint.
