Why this boundary matters
Inventory-file failures mix several kinds of problems. Some are mechanical, such as extra whitespace or a broken parent reference. Others depend on product facts, category rules, brand evidence, or Amazon-side catalog state. Treating them all as automatic fixes would be unsafe.
What SKUFix automates
SKUFix validates the workbook archive, detects the likely data sheet, normalizes processing reports, runs deterministic rules, maps evidence to cells, applies approved replacements, and verifies that no unintended cells changed.
What SKUFix does not do
It does not sign in to Seller Central, upload listings, scrape accounts, invent product data, generate identifiers, or claim it can override catalog ownership and authorization decisions.
