This object chooses whether to just resend an already-stored file to service modules, sendToSMsOnly, or to validate and save a new file into the database before sending, updateAndSend. This distinguishes re-pushing what is already staged from staging a brand-new file and pushing it, which matters operationally, since re-sending an already-validated file to a module that missed the first push does not require re-validating the file, saving time versus a full updateAndSend cycle. After a service module in one slot fails to receive a file due to a transient error, an admin can set this to sendToSMsOnly to resend the already-validated, already-stored file without repeating the validation step.
