Even the various wiki's don't agree which Guardian Stone affects archery - if it's Thief or Warrior. Was this question ever officially resolved?

Before patch 1.2 - Thief. After the patch (i.e. now)- Warrior.

That's why the wiki's disagree.

However, an Archer benefits from Sneak perks, so they'll use both stealth and combat skills.

Can anybody confirm that Fortify Archery governs dagger damage and not Fortify One Handed? I am almost sure this is so.
