+"""
+Idempotenter Bootstrap für Qdrant-Collections rund um Pläne.
+- Legt fehlende Collections NICHT neu an (wir erwarten, dass der erste Upsert sie erzeugt)
+- Legt fehlende Payload-Indizes als KEYWORD an (wo sinnvoll)
+- Zeitfelder: bleiben textuell (ISO8601); optional kann created_at_ts später ergänzt werden
+
+Start:
+  pip install qdrant-client --upgrade
+  python3 scripts/bootstrap_qdrant_plans.py
