Find the library, then find a content-only match

A local Calibre library is bundled with this skill.

A user asks for the book that discusses the relation between sense-data and physical objects and explicitly credits G.E. Moore.

Goal:

• locate the actual bundled Calibre library before searching
• identify the correct book from the library content
• report the book_id, exact title, and author
• include one short evidence snippet from the library lookup that supports the answer

Constraints:

• do not assume the library path without checking
• do not use title/author clues from directory names as the primary signal
• use library metadata or content lookup in the real bundled library data
• avoid guessing
• clearly state the lookup sequence you used, including how you found the library

Scoring should depend on the output being evidence-based and not based on file/folder names.
