A Gauge32, read-only, tallying sync-byte errors that were detected and corrected in the radio frame during the interval. Sync bytes anchor the receiver's bit and frame alignment, so a rising corrected-error count warns that lock margin is shrinking even while the radio is still recovering automatically. For example, an engineer diagnosing intermittent drops on a point-to-point wireless hop would watch cwr1SecCorrectedSyncByteErrs for a steady climb in the minutes before an actual sync-loss event.
