# reach the org-scoped branch of the route-permission gate (401 on denial),
# which fronts the handler's _verify_team_access. Only PROXY_ADMIN and an
# ORG_ADMIN of the team's org pass: an internal_user team admin is filtered by
# the route gate before _verify_team_access's team-admin branch is reached.
