+Name:        app/core/qdrant_points.py
+Version:     v1.2.0 (2025-09-05)
+
+Kurzbeschreibung:
+  Erzeugt Qdrant-Points für Notes, Chunks, Edges.
+  - Edges: 1D-Dummy-Vektor (Workaround).
+  - **NEU**: Edge-ID berücksichtigt optional 'occ' (Occurrence-Index),
+    um Mehrfach-Vorkommen von Wikilinks eindeutig zu machen.
+
+Aufruf:
+  from app.core.qdrant_points import (
+      points_for_note, points_for_chunks, points_for_edges, upsert_batch
+  )
+
+Kompatibilität:
+  - Bestehende Edge-IDs bleiben gültig; neue Edges können ein '@{occ}'-Suffix in der ID haben.
+  - Idempotenz weiterhin über UUIDv5 auf stabilem Key.
+
+Changelog:
+  v1.2.0: Edge-ID-Logik erweitert: "{kind}:{src}->{tgt}#{seq}@{occ}" wenn 'occ' vorhanden.
+  v1.1.x: Stabilisierung Note-/Chunk-Upsert.
