Really, then how does the system know you landed and not crashed on
approach?


ATC as in approach takes no overt action. The tower controller hits
the land line to approach and says "N12345 is on the ground" end of
IFR flight.


He does no such thing. No calls, whatsoever. There's no need to.

I've been in a tower cab when this happened. I've also been there when
they've hit the button, called the tracon and gotten a release.

Were they special occasions? I don't know I don't spend a lot of time
visiting.

Explain how it happens at your location.
