-Name:        app/core/qdrant_points.py
-Version:     v1.2.0 (2025-09-05)
+app/core/qdrant_points.py
 
-Kurzbeschreibung
-  Qdrant-Points für Notes/Chunks/Edges.
-  NEU: Edge-ID berücksichtigt optional 'occ' (Occurrence je Match):
-       "{kind}:{src}->{tgt}#{seq}@{occ}"
+Zweck
+- Gemeinsame Helfer zum Erzeugen von Qdrant-Points für Notes, Chunks und Edges.
+- Abwärtskompatibel zu altem Edge-Payload-Schema aus edges.py:
+    - alt: {'edge_type','src_id','dst_id', ...}
+    - neu: {'kind','source_id','target_id', ...}
 
-Aufruf
-  from app.core.qdrant_points import points_for_note, points_for_chunks, points_for_edges, upsert_batch
+Version
+- 1.3 (2025-09-08)
 
-Changelog
-  v1.2.0: Edge-ID mit '@occ' falls vorhanden.
+Änderungen (ggü. 1.2)
+- points_for_edges() akzeptiert jetzt beide Edge-Schemata.
+- Normalisiert alte Felder auf 'kind' / 'source_id' / 'target_id' und schreibt eine
+  stabile 'edge_id' zurück in die Payload.
+- Verhindert, dass mehrere Edges dieselbe Point-ID erhalten (Root Cause deiner 1-Edge-Sammlung).
+
+Aufruf / Verwendung
+- Wird von Import-/Backfill-Skripten via:
+    from app.core.qdrant_points import points_for_note, points_for_chunks, points_for_edges, upsert_batch
+  eingebunden. Keine CLI.
+
+Hinweise
+- Edges bekommen absichtlich einen 1D-Dummy-Vektor [0.0], damit Qdrant das Objekt akzeptiert.
+- Die Point-IDs werden deterministisch aus stabilen Strings (UUIDv5) abgeleitet.
