We had nothing about the star of the weeks, which was informally
specified. This clarifies that it's responsible for routine tasks, but
also takes care of clarifying the ticket workflow in the gitlab policy.

+### Triage
+
+One member of TPA is assigned the "Star of the weeks" every other
+week. The Star is responsible for triage, which occurs in GitLab, as
+per the [TPA-RFC-5: GitLab migration](policy/tpa-rfc-5-gitlab) policy.
+
+But the Star also handles routine tasks and interruptions. In that
+sense, it acts as a "[interruption shield](https://queue.acm.org/detail.cfm?id=1922541)" by taking care of
+small, distracting tasks to let others focus on more long-term
+projects.
+
+In that sense, the Star takes care of the above [routine tasks](#routine)
+like server reboots, security upgrades and spam runs. It is also
+expected to keep an eye on the monitoring system and organise
+[incident response](howto/incident-response) when a more serious issue occurs. It is *NOT*
+responsible for fixing *all* the issues and it is expected the Star
+will assign work or ask for help in an emergency or if it is
+overwhelmed.
