+derive_edges.py v1.9.0
 
-Zweck
------
-Robuste Kantenbildung für mindnet (Notes/Chunks):
-  • belongs_to (chunk → note)
-  • next / prev (Chunk-Sequenz)
-  • references (chunk-scope) aus Chunk.window/text
-  • optional note-scope references/backlink (Flag)
-  • optional Default-Kanten pro Note-Type aus Type-Registry (falls vorhanden)
-
-Abwärtskompatibel zu v1.4.0 (keine Pflicht auf Registry).
+Zweck:
+  - Ableiten von Edges aus Note + Chunks.
+  - Rückwärtskompatibel zu bisherigen Funktionen, inkl. Parametern:
+      build_edges_for_note(parsed, note_id, chunks, note_scope_refs=False, ...)
+  - Neu: Type-Registry wird optional benutzt, um fehlende Standardkanten je 'type'
+    (edge_defaults) zu ergänzen, ohne vorhandene explizite Kanten zu überschreiben.
