Books author-key disambiguation (Yale-collision) — 2026-09-22

OpenLibrary carries TWO Craig Wright author records that both appear in the ISBN graph of books/inventory.json:

• /authors/OL9970104A — Dr Craig S. Wright (our subject).
• /authors/OL2662936A — merged catch-all "Craig Wright", dominated by the Yale musicologist's Listening to Music textbooks (see audits/2026-09-21-books-4-candidates.md).

This audit walks each inventory ISBN → edition → work(s) → every sibling edition and records the raw OL author keys at every level. It replaces the S18 substring-based check, which returned ol_authors_empty for this ISBN and marked it verified despite the underlying attribution collision.

• Books in inventory: 1
• Verified (OL 200, no title/year/author-name flags): 0
• Unknown to OpenLibrary (404): 0
• Mismatched (OL 200 with flags): 1
• No ISBN in inventory: 0
• Errored / rate-limited: 0

Verdict roll-up

• SPLIT: 1

ESCALATION

The following inventory book(s) do NOT cleanly resolve to /authors/OL9970104A at every edition. Our "1 verified book" claim is SOFT — the OL edition that the S18 script probed is attributed to the merged catch-all key. A human eyeball on the Syngress author-of-record and the National Library of Australia record would settle it.

• The IT Regulatory and Standards Compliance Handbook: How to Survive Information Systems Audit and Assessments — verdict SPLIT
• MERGED key /authors/OL2662936A present — this OL author record is a known catch-all dominated by the Yale musicologist's textbooks.
• OURS key /authors/OL9970104A present (Dr Craig S. Wright).
• ISBN 9781597492669 (isbn_13) -> /authors/OL2662936A
• ISBN 1597492663 (isbn_10) -> /authors/OL2662936A
• ISBN 9780080560175 (ebook_isbn_13) -> /authors/OL9970104A
