A valid archive has the wrong reading order

A fictional publisher produces an EPUB from a controlled manuscript and reports that the archive opens without an error. The spine presents chapters in the wrong order, one image description is missing and the metadata describes a different edition. A proposed fixed-layout version is promised to look pixel-identical on every device. A visible watermark is treated as proof that every copy is authentic and legally reusable. No real publication is distributed here. The reading sequence has not been manually checked. Distinguish packaging syntax, reading sequence, accessibility, metadata, rendering and permission, and explain why successful opening or one visible label cannot establish all of those different requirements.
