Anything that doesn’t specify it doesn’t stack, stacks.
However some things that stack don’t practically stack—for instance, Offensive Buffs gives you Offense Up, Crit Damage Up, and a third one. But having Offense Up two or three or even fifty-eleven times doesn’t give more Offense Up than one instance of it.
tl:dr—if it says it doesn’t stack, it doesn’t stack. If it doesn’t say that, it does.
It's not that simple. A lot of discs didn't stack ('Entrenched' didn't just to mention one) in the first many Conquests. That might have been fixed. It might not have.
The example you give with buffs actually do make sense if it stacks. Sure, it doesn't make a difference if you have 1 offense up or 2 offense up, but it can trigger both characters and other discs (like 'Stacking Offense' that gives offense each time you gain a buff). So it matters whether they stack or not.
We need answers.
