(Bent /liG and /sic before bent are /kit when they are /iT-less and) after R ऋ.

The /kit prevents /guNa in —

kR कृ + soft liG /ta
→ kR कृ + **sISTa सीष्ट
→ !**kRSISTa कृषीष्ट

kR कृ + /luG /ta
→ kR कृ + /sic + /ta
→ kR कृ + /ta
→ !**akRta अकृत, a root aorist

Why "when /iT-less"?

When they do —

vR वृ + soft liG
→ vR वृ + **sISTa सीष्ट
→ vR वृ + isISTa इसीष्ट by ArdhadhAtuk...
→ vR वृ + iSISTa इषीष्ट with /Satvam
→ !**variSISTa वरिषीष्ट by gbS

vR वृ + /luG /ta
→ avR- अवृॱ + /sic + /ta
→ avR- अवृॱ + iS इष् + /ta by ArdhadhAtuk..., /Satvam
→ avar- अवर् + iS इष् + /ta by gbS
→ avar- अवर् + iS इष् + Ta ट by STunASTuH
→ !**avariSTa अवरिष्ट

or also

!**avarISTa अवरीष्ट, lengthening optionally by vRRtovA

Wait, why didn't we get ArdhadhAtuk... in **kRSISTa कृषीष्ट, **akRta अकृत?

Because kR कृ is an /aniT root.
