ੴ ਸਤਿ ਗੁਰਪ੍ਰਸਾਦਿ or ੴ ਸਤਿਗੁਰ ਪ੍ਰਸਾਦਿ

Gramatically which one is correct?

Also in ਸਤਿਗੁਰ ਨਾਨਕ ਪ੍ਰਗਟਿਅਾ, shouldn't there be aunkad in ੴ ਸਤਿ?ਗੁਰ

The correct one in my humble opinion is neither of the options you gave but is this one:

ੴ ਸਤਿ ਗੁਰਪ੍ਰਸਾਦਿ

Rest Gurbani is Agam Agaadh Both.

That is the second option bhai sahib.

Also how about the second question on bhai gurdas ji vaar?

One option is where "Sat" is place along with "IkOankaar". The option we support is where "Sat" is an independent noun with the meaning of Satya. The "ya" of Sanskrit becomes a sihaari in Gurmukhi in many cases e.g. this case.

I didn't understand your question on Bhai Gurdaas jee. Please rephrase it jeeo.

Apologies if it wasn't clear but the ਸਤਿ in the first option of the title was independent exactly as you mentioned. Is there a reason grammatically for this ੴ ਸਤਿ ਗੁਰਪ੍ਰਸਾਦਿ separation or just that it make more sense according to other mool mantar written in Sirlekh?

For ਸਤਿਗੁਰਨਾਨਕਪ੍ਰਗਟਿਆਮਿਟੀਧੁੰਧੁਜਗਿਚਾਨਣੁਹੋਆ।, the question is under what condition of the viakran rules is the rarra mukta in ਸਤਿਗੁਰ? I would think there should be aunkad in rarra because it's singular, masculine, without preposition, no sambodhan etc.
