Delete s स् of /tAs and /asti before s स्-affixes.

s of /asti —

/as + /laT /sip
→ a + sip by this rule
→ !**asi "you' are"

s of /tAs —

kR + /luT /sip
→ **kartAs- + /sip
→ kartA + si by this rule
→ !**kartAsi "you're gonna do"

kR + /luT /thAs → **kartAse

and with a /seT root —

bhU + /luT /sip
→ bhU + **tAsi
→ bhU + itAsi by ArdhadhAtuk...
→ bho + itAsi by gbS
→ bhav + itAsi by ecoyavAyAvaH
→ !**bhavitAsi "you're gonna be"

Why do we say "of /tAs and /asti"?

The s of other affixes and roots stays —

As + /thAs → As + /se''' → **Asse "you' sit"
