Jens wants the stem extensions -t-, -(e)n-, -(e)nt- and -r (of which
-t- is part of the ppp suffix -tó-) to be phonetic variants of a
single morpheme.

I want them to be variants of the verbal root PIE *dhe:- (elsewhere
known as *dheh1-), from PPIE *dhegh- "put, make" (inflected *gdhó:mi,
*de:i, *de:i; from the 3sg is reconstructed the root PIE *dheigh-).
That means the agent noun suffix -t is from *-d from *-dgh (from
*-dhgh by Bartholomae); *-d > *-t in auslaut in some suffixless PPIE
'old nominative'. If further PIE /d/ is really prenasalized /Nd/ as I
assume, we have a good starting point for > -Nd- > -nd- > -nt-, -Nd- >
-d- > -r-, -Nd- > -n-.
