I was surprised that you did not recognise what I meant when I said mindfulness is non-reactive
But we can pursue to entirely from an academic perspective if you prefer.
sati leads to samadhi (onepointedness) [see the five spiritual faculties] and that can lead to equanimity [see the the seven factors of enlightenment] atapi
refers to effort
effort to be mindful, effort leads to mindfulness [see five spiritual faculties]sampajano, satima
common translation- clearly knowing, clear comprehension
but look at what the suttas say (in short it refers to seeing arising and passing away)
yes we do start with being mindful of the daily duties, but then our mindfulness faculty grows so that we can become aware of distinct movements of our bodies while doing those duties and seeing how they arise, persist and pass away.
Mindful & Alert (satima sampajano). Stay mindful, monks, and alert. This is our
instruction to you all. And how is a monk mindful? There is the case
where a monk remains focused on the body in & of itself — ardent,
alert, & mindful — putting aside greed & distress with reference to
the world. He remains focused on feelings... mind... mental qualities
in & of themselves — ardent, alert, & mindful — putting aside greed &
distress with reference to the world [§213]. This is how a monk is
And how is a monk alert? There is the case where feelings are known
to the monk as they arise, known as they persist, known as they
subside. Thoughts are known to him as they arise, known as they
persist, known as they subside. Discernment (vl: perception) is known
to him as it arises, known as it persists, known as it subsides. This
is how a monk is alert. So stay mindful, monks, and alert. This is
our instruction to you all.

putting aside craving and aversion/sadness (which is a form of aversion, arising from craving) because the hindrances need to be kept at bay to some degree otherwise we would be lost in thoughts generated by those hindrances, unable to maintain mindfulness. some people here would know how useful developing one-pointedness (samadhi, samatha) is to the development of sati. The same mechanism works there.
