3.47.0 (2026-09-16)

The engine predicates adopted: identifierless listing, tag-tree rollups, pace year buckets, engine-driven duplicates

• --identifierless: books carrying no identifiers at all, listed as [id] title through cquarry's find_identifierless (L4 rank 11's curation queue for Calibre-Companion-style lookups); a fully identified library reports clean.
• Tag-tree rolled-up counts: every node of --tags --tree's taxonomy now shows its rolled-up book count -- a node's total is the sum of the leaf tags beneath it (cquarry's tag_rollup arithmetic, rendered in the tree).
• --analytics pace --pace-granularity year (L4 rank 10): the addition timeline buckets by year instead of month.
• Duplicate detection is the engine's predicate now: the audit's hand-rolled (title, primary author) grouping is replaced by cquarry 1.8's find_duplicate_books -- same key shape, but the ids inside a duplicate row are sorted numerically where book-iteration order used to decide (the one visible CSV difference).
• The stale series-clear pin updated to the cquarry 1.23.1 fixed semantics: a cleared series resets series_index to 1.0, never NULL on real schemas.
