Apparently, GC does in fact support private tickets via the label "private." (NB: when adding the "private" label, GC notes that you're using "an uncommon label" but it does make the ticket only visible by project members.)
To support importing them, we will need to perform authentication via AuthSub, requiring additional info from the user during either tool or project import.
Somehow, I missed the Permissions system documentation, in favor of which the "
private
" label has been depreciated.Private tickets are indicated by some form of a "
Restrict-View-*
" label, which restrict the ability to view the ticket to users with that permission, which is managed on the People tab.It's a bit more fine-grained than Allura's private tickets, though it can be replicated via the use of groups.
It's unclear how common the usage of this is, but it's certainly more prevalent than the "
private
" label.
