Why do all clocks agree?

All clocks agree because each one is a reading of the same repair history. The basic clock counts every repair that touches a region, idle ones included. Regions are touched at different rates, yet each count, divided by its expected rate, converges on one parameter, with nobody synchronizing anything. The fluctuations of that traffic form a field that relaxes in the same count. A small memory stepped once per touch oscillates as a wave in that count. A disturbance reaches a distant region exactly when the count equals their distance, which makes the speed of light the exchange rate between count and ruler. A region's own internal flow matches too, scaled by its temperature. Satellite clocks gain forty-five microseconds a day because they sit where the settled state is colder, and they agree after conversion. Attaching normalized count ratios directly to published optical clock frequency ratios is rejected by the data, so a count becomes a reading in seconds only through a calibration that models the measuring apparatus.
