The airflow check reads the purge fan's off current with the fan off, and the stand-down that follows commands it back on. The guard that proves the machine was handed back whole read the draw immediately, so what it got back was the off current the check had just measured: on the bench reference, 74 against a 300 floor, with the fan drawing 631 a moment later. The check failed for having worked. The current follows the command; it does not arrive with it. The guard now waits for the draw to reach the floor, up to PURGE_SPINUP_S, the way the controller below it is already waited for, and logs how long it took. It is no weaker: a fan that never reaches its floor still fails the check, and the message now says how long it was given. Pin: forgectrl 0.1.17 (a9e7073, the air assist and the purge in the diagnostic run posture - the reason that check measured an idle fan and wrote a floor from it).
