Re-open a closed role from the role page menu, Re-open. The role goes live again under the same slug, the same rubric, and the same brief. Anything you change at re-open time is logged in the role history.
The prior candidate pool stays archived. Already-vetted candidates from the prior run are visible in the role history but do not re-enter the active pool. If you want a prior candidate to be reconsidered, you re-invite them from the candidate card, which sends a one-line note: "We are re-opening this role and we would like to talk again". That invite is logged and counts as a new vetting cycle for billing.
What to do next: re-open the role, edit the brief if the scope has changed, and invite the one or two prior candidates worth revisiting.
