 - Total power is computed on receiver as `p1 + p2 + p3`.
 - Sender error counters are carried in the batch header and applied to all samples.
 - Receiver ACKs MeterBatch as soon as the batch is reassembled, before MQTT/web/UI work, to avoid missing the sender ACK window.
+- Receiver repeats ACKs (`ACK_REPEAT_COUNT`) spaced by `ACK_REPEAT_DELAY_MS` to cover sender RX latency.
