@k-arrows: Do you have triage role? If not, please request it, so you label issues much better than bot. Procedure is same as for commit access.

#87199

[lattner]

@EugeneZelenko this is news to me. I don't know anything about a triage role.

[EugeneZelenko]

@lattner: @tstellar filed several issues with downgrading access for inactive accounts from commit to triage role: https://github.com/llvm/llvm-project/issues?q=is%3Aissue+is%3Aopen+label%3Ainfrastructure%3Acommit-access.

[lattner]

Ok, well there is no mention of triage roles in https://llvm.org/docs/DeveloperPolicy.html

[tstellar]

I always tell people who want triage access to apply for commit access. We don't have a process for requesting triage access yet.
