Is there an authoritive/verified guide etc to Perk Entry Conditions/priority/processing somewhere?

[PJMail]

For instance (in a single Perk):
- For a single Perk Entry, are the various condition tabs AND, OR, or exclusive? i.e. If you have conditions under each tab, how are they processed?
- If 2 entries have the same condition (for different Entry point modifiers) can they both be triggered? Or is only the one with the highest priority active?
- Similarly, if you have multiple Perk entries and an effect matches a number of them, do they all operate (or only the highest priority one)?
- If all, then in what order, and what actually is Priority for?
- Does "swap Subject and Target" actually work to apply a condition to the Attacker? I am thinking of Entry Points Like "Mod incomming Explosion Damage" which only offer conditions for "Perk Owner" - would the swap option apply the condition to Attacker instead (like it is documented to)? Or to the Explosion? Or what?
- Why do some Entry Points have multiple condition Tabs (when you can put the same condition in any of them)? What is special/exclusive about the processing of conditions under each that requires them to have their own tab (e.g. Perk Owner or Target Tabs) when conditions already have Subject and Target available anyway.

I am not after guesses, but actual verified functionality by people who have tested this (as Bethesda documented nothing).

And for FO4 (as Skyrim is NOT the same).

Thanks.
