"triaged" vs "confirmed"

[Martin Pool]

What exactly is the distinction between these states?

In the past when we (Bazaar developers) did triage we would generally
set things to invalid, confirmed (if it was a bug), needs info (if we
weren't sure if it was a real bug and needed more  information from
the user or a developer), or fix released (if it was already fixed).
I'm not sure where "triaged" should fit in -- is it supposed to mean
"i'm not sure if this is a bug, but if it is it's $priority"?  What
action should that drive?
