EVERY ROW IS READ FROM SYSTEMD, NOT TYPED: A NEW TIMER APPEARS HERE ON ITS OWN. FAILED MEANS THE LAST INVOCATION EXITED NON-ZERO, WHICH ON THE SHORT-CYCLE GMFM LANES ALSO COVERS A DELIBERATE FLOCK SKIP WHEN THE PREVIOUS RUN IS STILL GOING. STALE MEANS NO RUN IN 1.5x THE LANE'S OWN INTERVAL. RETIRED MEANS A DATED ONE-SHOT THAT HAS FIRED.
