All padafinal r र् (including punar and family) and the s स् that follows non-a अ vowels ( **gIr गीर्, **gurus गुरुस्) always give the same result, because that s स् becomes r र् by sasajuSoruH and that r र् coming from s स् is never caught by hazica or atororapl....
So they become —
Before all vowels — r र् by no rules
Before pause — H ः by kharavasAn...
Before r र् — nothing (by rori), and then previous a अ i इ u उ lengthens (by DhralopepUrv...).
Before other /haz — r र् by no rules

Before p प् ph फ् k क् kh ख् — H ः by kupvoKkaFpauca, or by zarparevis...
Before ts त्स् — H ः by zarparevis...

Before c च् ch छ् — z श् by visarjanIy... and stozzcunAzcuH
Before T ट् Th ठ् — S ष् by visarjanIy... and STunASTuH
Before s स् — s स् by vAzari
Before z श् — s स् by vAzari and stozzcunAzcuH
