 If it is unclear what area an issue belongs to, the supervisor asks for advice from other team members on Slack or GitHub. If, after asking for advice, it turns out that nobody in the team knows how to classify it, the issue must be classified with a “stat:needs triage” label.
 
 If it is unclear who should review an external PR, the supervisor asks for advice from the rest of the core team. If after asking for advice, it is still unclear who should do it, the reviewer for such a PR will be decided at the next Dotty meeting.
 
-In general, if anything else is unclear for proper fulfillment of responsibilities, the supervisor must proactively seek advice from other team members on Slack or other channels.
