Thanks for the review. The commit message was unclear, apologies.
Without passive_delay, the governor fires only on trip crossing interrupts.

Can we use something like below in commit message:
"Without passive_delay, the governor fires only on trip crossing
interrupts. Temperature stabilizing between two trips generates
no interrupt, so not all cooling levels are applied. Set
passive_delay to enable periodic polling to ensure all cooling
is applied."
