What This Error Means in Plain English

Apple Books has strict package ingestion rules. The cover image must have properties="cover-image" declared in the manifest, and every spine item must be linear and cleanly indexed.

Why Retailers & EAA Regulations Block This File

Apple's automated ingestion server rejects the file at upload time and refuses delivery to the Apple Books store.

Technical Specification: Apple's Transporter validates the presence of the cover-image property on exactly one <item> in <manifest>, and ensures linear spine items follow strict sequence.

Manual Fix Instructions (for Sigil / Calibre)

In content.opf, locate your cover image item.
Add properties="cover-image" to its <item> tag.
Ensure the spine references valid manifest items in sequential reading order.
