Debates typically (should) end in a final decision.
There should be an easy why to flag/tag/status/whatever it and it should be very easy to find all final decisions. Even if this feature is only available in on posts for private teams as this is typically where the shortcoming is. Once available it could be very useful everywhere else.
This is the ONE feature I find missing from Ryver (and almost any other tool).
As to how to implement in Ryver . . . i leave that up to you guys, sure you'll come up with a nifty plan.
Quick suggestion . . .
A comment (message) with a specific flag/tag/status/whatever that can be set only with the relevant access credentials.
