Completeness and readiness are different questions
This check asks whether product records have enough reliable filename matches and whether image files cross the explicit minimums you entered. It does not establish that the product listing itself is factually correct or approved for a marketplace.
Use it before the store or PIM
This is a platform-neutral preflight. It does not need store credentials and does not write to Shopify, WooCommerce, a PIM or a marketplace. Use it to make the package understandable before import, migration or handoff.
Unclear matches stay unclear
Near or competing filename relationships are shown for review instead of being promoted to confirmed coverage. Resolve naming or record ambiguity before treating the pack as complete.
Re-check the final pack
After obtaining missing files or correcting output copies, run the same pack check again. If a marketplace or client has additional explicit rules, continue with a more specific readiness check.
