It is unrealistic to assume (and it is an assumption) that (Su) acts differently in this respect without something to specifically say it acts differently. The fact the (Su) doesn't say it overrules the ranged attacks rules is quite telling in itself.
I do not see why it is unrealistic to speculate that a ruling on one type of ability does apply to a different ability type. It is an assumption that Supernatural doesn't act differently.
That said, I have agreed with your stance at least twice in this thread as being the likely RAI. Unfortunately, my point still stands that it is a gray area. A FAQ on AoO's+Spells+Rays is a good jump point to base unlisted answers such as this one, but it is not final authority on it.
No matter how many times it is said that "ranged attacks provoke", that does not change the fact that specific rules can overrule the general rule, and the only specific rule regarding Supernatural abilities and AoO's indicates that there isn't an AoO. There is a direct conflict of specific vs general here, and typically when that occurs the specific overrules the general.
I understand that you are pushing your stance hard on this, and I appreciate that input because that is partly what I was looking for in this. But we're going in circles on what is clearly a gray area. The rules do not state anywhere in plain text that "ranged attacks granted by a Supernatural ability provoke an AoO". The abilities themselves do not indicate that it provokes at any point. We have a specific rule saying 'no' and a general rule stating 'yes'.
I'm not trying to exploit the rules, mess with a GM, or anything like that. I happened to find something in the rules that opens a gray area that for some reason has not been answered and I would like to know with certainty what that ruling is.
Spell like abilities also don't say that the ranged aspect provokes.
Correct. But Spell-like abilities are also listed in the previously referenced chart as provoking in the first place. The only clarification needed there was how many times it provoked. The difference here is that the Supernatural ability has a hard NO for AoO's, which can be open for interpretation.
If you can say "there is a rule that states that ranged attacks provoke" and I can counter that with "there is a specific rule on this ability type that shows that it doesn't provoke", then a clarification is needed. It bothers me that you can't concede that point.
