So... Obviously I was in the Class C, and though I was still on
approach frequency, I do not think that I was still in radio contact,

Is a NASA ARS form appropriate? Was I wrong and did I bust the C?

Nope you didn't bust class C. The controller terminated radar
service, but you're still on his frequency were you? You should,
however stay on his frequency until you're cleared of class C, or to
receive prior permission to change frequency if you're still in class
C.
