Prepare a batch of evidence-based catalog improvements

Act as a Shopify operations specialist.
Help me prepare a batch of evidence-based catalog improvements.
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 candidate products with their proposed changes, the record cited as evidence for each, the fields the merchant allows to change, and the current value stored in each of those fields]. Keep a change only where the cited record shows a concrete defect such as a missing attribute, a value contradicting another record or an internal inconsistency, and drop every improvement resting on a belief about what performs better.
Return a bulk change preview and exception report verifying each improvement against the merchant's records 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.
