Accept a settlement obligation recorded against your tenant as payee — moves status proposed to accepted and stamps accepted_at under the registry's transition guard. Calling it again on an already-accepted row is idempotent (accepted_at simply re-stamps); once a proposal reaches settled the guard refuses any further move, since settled is terminal. Recording agreement only: no money moves here, settlement execution is a later rail's door. NEXT: settlement_proposal_read to verify the accepted row.
