 Changelog
-  v2.3.0: Umstellung auf app.core.derive_edges + Note-Index vorab; Edge-IDs unterstützen Occurrence.
+  v2.3.1: FIX – Für derive_wikilink_edges werden jetzt echte Chunk-Texte übergeben
+          (chunks_for_links mit {"chunk_id","text"}), damit `references_at` erzeugt werden.
+  v2.3.0: Umstellung auf app.core.derive_edges; Edge-IDs unterstützen Occurrence.
   v2.2.x: Fix Filter-API (pydantic v2) bei Purge; Kleinkosmetik.
