The panel driver counts ring refills, the largest gap between refills, frame swaps, swap timeouts and I2S TX FIFO underruns (takeStats()). The ESPHome component checks them every 10 s and logs a warning only when the ESP32 side of the signal had a problem, plus a debug summary per minute. Measured with Wi-Fi on: ~4600 refills/s, max gap < 0.4 ms (lead 1.7 ms), no underruns or timeouts, so remaining blinks come from the signal being disturbed on the wires (Wi-Fi transmit bursts), not from the refresh.
