@crushing of tu

Whenever t त् th थ् d द् dh ध् happen to be padafinal, they are replaced with d द् by jhalAJjazonte —

**indrajit- इन्द्रजित् + /su
→ indrajit इन्द्रजित् by halGyAbbhyodIrgh...
→ indrajid इन्द्रजिद् by jhalAJjazonte

**suhRd- सुहृद् + /su
→ suhRd सुहृद् by halGyAbbhyodIrgh...

**hRd- हृद् + /su
→ hRd हृद् by svamornapuMs...

**suyudh- सुयुध् + /su
→ suyudh सुयुध् by halGyAbbhyodIrgh...
→ suyud सुयुद् by jhalAJjazonte

This d द् will be replaced, by vAvasAne, with t त् before a pause —

indrajit इन्द्रजित् + pause → indrajid इन्द्रजिद् → indrajit इन्द्रजित्

will stay, by no rules, before vowels and /haz —

bhagavat- भगवत् + gItA गीता → bhagavad भगवद् + gItA गीता by jhalAJjazonte → bhagavadgItA भगवद्गीता

and will turn into t त्, by kharica, before /khar —

indrajittatra इन्द्रजित्तत्र

After that,the थे t त् or d द् will maybe be affected by other rules, like stozzcunAzcuH or STunASTuH.

I have the bad custom of sometimes writing padafinal d द् as t त्, or t त् as d द्, without warning you that one of the above rules is working. Sorry. You will have to get used to the idea that those two are interchangeable.
