what is the origin of vrddhi in denominal derivatives in Sanskrit?
How could e.g. graiva- arise from gri:va:, or sauma- from soma-?
Piotr has mentioned "e-insertion" into the main syllable, but this
would not explain forms like graiva-, and does not explain why the
process of "e-insertion" should arise in the first place.

If you believe that o > o: > a: in some environments [1] in
Indo-Iranian, then nothing is needed but the analogical extension of
the rule to cases where it wouldn't happen regularly. Thus the o-e-0
ablaut was mainly replaced by a:-a-0 (and in cases where only the
0-grade survived at the time of this analogy, the a(:) might have been
inserted in the wrong place from a historical perspective).
1 I believe specificly:
o -tone > o: /
when followed by a syllable +tone
and o at the end of a syllable
unless at the end of a word
o +tone > o: /
when followed by a syllable -tone
and o at the end of a syllable
