Resume Function

Resume completes the pause lifecycle and is what makes the pause function safe to adopt: volunteers will only trust a pause feature if returning is equally frictionless. Without a clean resume path, paused mentors drift into permanent inactivity and the retention benefit collapses. The resume flow also acts as a controlled gate where the platform can surface remediation needs (expired certification, missing consent), turning a routine reactivation into an opportunity to keep records compliant. Coordinators gain timely visibility of returning capacity, enabling them to dispatch waiting assignments without manual re-onboarding.

Resume transitions the peer_mentor_status record back to active and emits a coordinator notification mirroring the pause flow. A pre-resume validation hook checks blocking conditions - most importantly an expired certificate, which intersects with Certification Expiry Auto-Pause - and surfaces a clear remediation path rather than allowing an invalid active state. The mentor is re-included in assignment matching, geographic visibility, and capacity reports on the next sync tick. Offline-initiated resumes queue via the sync outbox. UI mirrors the pause confirmation pattern, with the same WCAG 2.2 AA requirements (touch targets, focus, screen reader labels, error messaging with suggested fixes).
