When are Landmark rules in effect?

By dickens1853, in Battlelore

I scoured the rules, and all I could find was "An Adventure’s battle notes will state when Lore Master Landmark rules are in effect." Rarely do I actually see this stated in the scenario notes. Can I safely assume that whenever full Lore rules are used, then Landmark rules are also in effect (assuming there exists a level 3 Lore Master)?

Thanks.
