# issue-triage.yml — Automatic Forgejo issue status label transitions
#
# Copy to .forgejo/workflows/issue-triage.yml in any CF product repo.
#
# Transitions:
#   PR opened/reopened → status:review on issues referenced in PR body
#
# Note: status:in-progress is handled by the pre-push hook in circuitforge-hooks,
# which fires deterministically on the developer's machine when pushing a branch
# named feat/N-*, fix/N-*, etc.
#
# Requires org-level secret: FORGEJO_TOKEN (read:issue + write:issue scopes)
