Define and pilot a volunteer-stewardship process

[jcklpe]

Goal

Give onboarded volunteers a clear path to useful first contributions, continuing support, and shared organizational responsibility.

Tasks

• Define the handoff from volunteer onboarding in Research and iterate volunteer onboarding #474 into ongoing stewardship.
• Establish an organization norm for rotating recurring administrative work and documenting each handoff.
• Create a lightweight good-first-task checklist or template, including the SOPs needed to complete each task.
• Review one-off and evergreen open roles for accuracy and define who maintains them and how often.
• Define who checks in with volunteers before and after their first contribution and helps identify an appropriate next step.
• Pilot the process with one or two volunteers and participating Teams.
• Route technical records or automation needs through Explore a lightweight way to track members and contributors #506 rather than duplicating that work.

Done when

• The onboarding-to-stewardship handoff is documented.
• The admin-rotation norm and first-task template are usable.
• One-off and evergreen roles have a documented maintenance owner or cadence.
• At least one pilot has produced feedback and a recorded next step.
