Additional troubleshooting information

For the Written Statement for Unauthorized Debit playbook activity for ACH disputes:

• The sn_doc_processor.external_user role is added to sn_bom.customer and sn_bom.consumer, enabling customers and consumers to view and electronically sign WSUD documents through the portal.
• The sn_doc_processor.agent role is added to sn_bom_credit_card.dispute_agent and sn_bom_credit_card.dispute_agent_connector, allowing dispute agents and connectors to verify and manage WSUD documents during case review.
• When transactions are modified in the Review lane, the WSUD document is automatically regenerated and a new e-signature link is sent to the customer when the required conditions are met.
• If the dispute reason code is changed to one that doesn't require a WSUD, the associated Document Verification task created during intake is automatically canceled.
