Official EPUBCheck & AR Tool QC Reports
Validation date: 11 October 2026. The supplied AR Brand New EPUB Production/QC Tool v2.58 includes the official EPUBCheck 5.4.0 distribution. Each file below was validated against its exact SHA-256 fingerprint; the tool's EPUB Audit was also executed.
EPUBCheck results: 12/12 PASS, with zero fatal errors, errors and warnings. This confirms EPUBCheck checks only. DAISY ACE has NOT been run. Screen-reader accessibility, reading-system layout, mathematical speech and fixed-layout verification remain pending. Fake ISBN identifiers in four updated portfolio samples are demonstration-only and do not represent registered ISBNs.

Unfinished accessibility checks
- DAISY Ace CLI is not installed or bundled with this v2.58 tool.
- Assistive-technology and device-specific readers have not been tested.
- Metadata reflects the content features we can substantiate; it is not accessibility certification.
- Four original portfolio EPUBs remain byte-for-byte unchanged to preserve earlier QC PDFs. New modified sample versions have newly generated EPUBCheck evidence.
- Sample-only ISBN-form numbers are illustrative placeholders, never registered publication identifiers.
