+# hyphenation / orthography — query and corpus use different hyphen
+# conventions for the same concept. FTS5 `unicode61` splits on hyphen
+# at index AND query time, so `bi-polar` (the orthography many
+# English readers actually use) tokenizes to [bi, polar] while the
+# Wikipedia article `Bipolar disorder` tokenizes to [bipolar]. Two
+# non-overlapping token sets for the same medical condition. The
+# query-layer hyphen-fold (Ticket #000007, 2026-05-02) closes this
+# class by emitting joined-no-hyphen variants on the query side and
+# adding a hyphen-anchor accept path in `_filter_by_title_relevance`.
+# Pre-fix: only Bi-Polar (album) / Bi-Polar Blues / BI disambiguation
+# surfaced; the medical-condition cluster never reached the LLM.
+# Post-fix: `Bipolar disorder` lands in top-K and grounds the answer.
