कौषीतकि ब्राह्मण (शाङ्खायन ब्राह्मण - उदय प्रणीत व्याख्या सहित सटीक)

' there are two strokes for 'ै': one stroke, second stroke.
Is there a repha?
Let's look at "ब्रह्मणैव":
It's just "ब्रह्मणैव"! (brahmaṇā + eva = brahmaṇaiva). In Sanskrit, it's ब्रह्मणैव. There's no "ब्रह्मर्णैव".
Wait, look at the image line 34:
"ब्रह्मणैव तद् ब्रह्म⁶ समर्धयति" - yes, it's ब्रह्मणैव!

Line 35:
"ग्र्न्यो तृचावन्वाह ।१४। अग्निं हि पूर्वं⁷ हरन्ति ।१५। तौ वा इतश्चेतो भवतः ।१६। ह्रिय-"
Wait, "ग्र्न्यो"??? Look at line 34-35:
Line 34 ends with: "केवला-"
Line 35 starts with: "ग्न्यो" or "ग्र्न्यो"?
Wait, look at the start of line 35:
ग with a subscript न: ग्न.
Then an o-matra: ग्न्यो.
Wait, is there a र-फला?
Look at it: it has ग, and a stroke? It is "ग्न्यो" (kevalāgnyo -> kevalāgnyau / kevalāgnyoḥ? kevalāgnyau = kevalāgnyo).
Wait, look at the first consonant of line
