Forward a signed LoA to the losing carrier and move the signature state to submitted. Provider-dispatched requests send the document to the carrier; manual-mode requests transition locally so ops can hand off the signed PDF out of band. The LoA must already be in signed state. A carrier-side failure is logged but does not block the local transition — retry the carrier step via the refresh endpoint. Requires the numbers:write scope.
