Editorial and review notes
- Diagnostic fixture only; it is not independent ground truth and has not been owner-approved.
- Compared the complete skipped-book notice against the authoritative page image.
- The source endpoint remains literally Nov. 28.; the diagnostic normalization to 1897-11-28 is explicitly marked inferred from the year-bearing start of the same range.
- Explicit owner action: approve_as_is.
- Approval lineage begins with diagnostic SHA-256 62e29a09aa03e5c952bf8ecc9ad4511528381db11c9c4730b35c322c0399e316.
- Owner visually compared the diagnostic with the authoritative scan and approved it without further changes.
