Linking Perks to Weapon conditionals

[SKKmods]

I am trying to trace the link from Fo76 damage perks to weapons, for example how does:

 

Rifleman identify non automatic rifle condition

Commando identify automatic rifle condition

 

I would expect a WeaponTypeAutomatic keyword conditional, but cant find any on the player perk, spell or damage modifier: Commando01 > abPerkCommando > abPerkFortifyDmgRiflesAuto
