Perhaps a nitpick, but the Festnachspiele were late 15th century while Gemini refers to the 16th. This may be a normal AI 'inaccuracy'.
I also remember Anton writing that these terms were 'all over', which may have been an exaggeration, but it differs from Gemini's 2 counts.
By the way, there is also this paper: Eugene F. Clark, The Influence of Hans Folz on Hans Sachs, Modern Philology, Vol. 15, No. 6 (Oct., 1917), pp. 339-348
which can be found online.
The combination of lung and liver in both cases seems to me to be a clear example of either direct influence or wider usage.
