It matters very little either way. The point I want to make
though is that even if we accept that final voiceless stops became
voiced as shown by ProtoSteppe *-it supposedly becoming EA *-d,
the 2ps in *-t obviously can't be from the identical transitive 2ps
*-it, but rather from intransitive *-un, whereby final nasals
become stops. Likewise, your *-k comes from Boreal intrans.1ps *-uh
which in turn comes from ProtoSteppe *-uh. The system I propose
for Boreal (parent of Uralic, CK and EA) would be something like
the following:
TRANS INTRANS
1ps *-im *-uh
2ps *-it *-un
3ps *-isa *-u
It differs from earlier ProtoSteppe in that the general postpositional
demonstrative *sa, originally just used to mark the animate nominative,
came to be used as the 3ps marker (which was originally simply *-i in
Steppe).
We can see how it evolved into IE, since the intransitive was converted
(by the suffixed *-e) into a perfect aspect while the transitive became
the basis for the durative-aorist system. The connections are there.
