Do not begin final output while facts are still moving. Confirm name or organisation, role or service line, primary contact details, web or social destination and optional address or short descriptor and record the approved revision. Treat every phone number, email address, URL and spelling of a name as production data requiring independent verification.. Run spelling, design and accessibility reviews, then save the editable .mpub before creating a PDF. A later correction needs a new proof; editing after approval without repeating review breaks the audit trail.
