-Modul: app/core/chunk_payload.py
-Version: 1.1.2
+Script: import_markdown.py — Markdown → Qdrant (Notes, Chunks, Edges)
+Version: 3.1.1
 Datum: 2025-09-09
 
 Kurzbeschreibung
 ----------------
-Erzeugt Qdrant-Payloads für Text-Chunks einer Note. Jeder Chunk enthält
-den tatsächlichen Text unter dem Schlüssel ``text``. Dadurch kann der
-Exporter den vollständigen Body verlässlich aus Chunks rekonstruieren,
-falls ``notes.payload.fulltext`` fehlt.
+Liest Markdown-Dateien aus einem Vault ein und schreibt Notes, Chunks und Edges
+idempotent nach Qdrant. Change-Detection basiert standardmäßig auf dem **Body-Hash**
+(ENV: MINDNET_HASH_MODE). Persistiert zusätzlich den Volltext der Note unter
+``payload.fulltext`` und speichert den Vault-Pfad relativ.
 
-Wesentliche Features
---------------------
-- Stabile, idempotente Payload-Struktur für Chunks
-- Persistenter Chunk-Text (``text``)
-- Extraktion von Wikilinks pro Chunk (``wikilinks`` & ``references``)
-- Pfadübernahme (relativ zum Vault, wird vom Aufrufer geliefert)
-- Bereinigung leerer Felder (keine ``None``/leere Collections im Payload)
+Abwärtskompatibilität
+---------------------
+- Keine harte Abhängigkeit mehr von nicht gelieferten Modulen (validate_note, embed, edges).
+  * Embeddings: Nullvektor-Fallback (Dim aus ENV/Config).
+  * Edges: werden aus Chunk-Payloads + Note-Refs lokal abgeleitet.
+- IDs, Collections, Upsert-Semantik unverändert.
 
-Abhängigkeiten
---------------
-- ``app.core.chunker.Chunk`` und ``assemble_chunks``
-- ``app.core.parser.extract_wikilinks`` und ``read_markdown`` (nur CLI)
+ENV / Qdrant
+------------
+- QDRANT_URL (oder QDRANT_HOST/QDRANT_PORT)
+- QDRANT_API_KEY (optional)
+- COLLECTION_PREFIX (Default: mindnet)
+- VECTOR_DIM (Default: 384)
+- MINDNET_HASH_MODE: "body" (Default) | "frontmatter" | "body+frontmatter"
