Resume Function

The resume flow closes the lifecycle loop opened by the pause function. Without a structured resume path, paused mentors remain inactive indefinitely due to friction or forgetfulness, eroding the active mentor pool over time. A guided resume flow reduces this risk and gives coordinators a mechanism to prompt mentors who have been paused for extended periods. For organizations dependent on volunteer capacity - HLF and NHF in particular - retaining experienced mentors through structured lifecycle management directly supports program continuity and reduces the cost of onboarding replacements who lack the same depth of relationship experience.

Resume is a status transition on peer_mentor_statuses (paused to active), triggered from the same Pause Toggle Screen used for the pause action. A brief confirmation step optionally verifies the mentor's availability preferences before the backend clears paused_at, resets status to active, and dispatches a push notification to linked coordinator(s). The flow must handle the expired-certification edge case: if certification lapsed during the pause period, the backend returns a validation error and routes the mentor to the certification renewal flow rather than reactivating directly. Status transitions must be atomic so no partial state persists on network failure.
