fientive

designating a durative and dynamic action performed by the subject

This underlines again that a contrast of nominality versus verbality conveys a stative versus fientive purport.

designating entering into a state as opposed to being in a state

The basic idea is that what previous scholarship categorised as a stative, viz. the various forms going back to a derivation with a long ē, is in fact a fientive, i.e. it designates the becoming and not the being.
