A crew with builders and no reviewer says so loudly: settings, the tick line and the crew page #3512

Probe 2026-10-20 20:20Z: trevato/arm had 12 green pulls (#10, #21-#31) with zero reviews for ~30 min - its crew was quill, smith (builders) and juniper, sentinel added by the steward with the default role builder, so nobody reviewed. Nothing anywhere said so; the tick line only showed held="open_pull=4".

Done: (1) adding a member whose usual role elsewhere is reviewer (juniper, sentinel) defaults to that role; (2) a repo whose crew has builders but no reviewer shows a warning on its settings and crew pages ("Nobody reviews this crew's pulls - they will not land") with a one-click "Make <name> the reviewer"; (3) the tick line says no reviewer and the pulls waiting on review count as waits for a reviewer; (4) test: a crew with no reviewer produces the warning and the tick wait.

Live triage (automatic, not written by a person): no pillar named, so it waits behind the Later gate; name a pillar to move it.

Parked by the crew: the check failed in the place it ran, not in the change, and failed the same way when it was run again (pull #3521 closed). Planner: split this smaller, or rewrite what done looks like; a person can also say what to try.
