Structure a maintainable customer support knowledge base

Act as a Shopify operations specialist.
Help me structure a maintainable customer support knowledge base.
My store context is [describe the business, products and target audience].

My scope is [specify the affected products, pages, customers or reporting period]. Use these inputs: [the approved policy documents, product references and existing macros with each owner and last revision date, the questions support repeats most and the recorded conflict resolutions]. Group the questions into topics by what the shopper asks, resolve conflicts between sources by recording which source wins for that topic and keeping the version its owner confirms, and mark questions no approved source answers as needing one.
Return a support knowledge base outline and grounded FAQ answers, each traced to a source and its update date for the specified task.
Show the relevant evidence or before-and-after examples and explain how I can verify the result.
If essential data is missing, ask for it and mark unsupported conclusions as unknown.
Do not invent metrics, product claims or customer facts.
For any publication, message, account or store change, use only connected tools within my explicitly authorized scope and report success only after verification; otherwise provide the draft or proposed steps.
