+tests/assert_payload_schema.py  (compat v1.1)
 
 Prüft, ob die erwarteten Payload-Indizes (payload_schema) auf den drei Collections vorhanden sind.
+Kompatibel mit älteren qdrant-client Versionen (ohne with_payload_schema im Wrapper).
+
+Collections & Pflichtfelder:
 - mindnet_notes   : note_id, type, title, updated, tags
 - mindnet_chunks  : note_id, chunk_id, index, type, tags
 - mindnet_edges   : note_id, kind, scope, source_id, target_id, chunk_id
