 Kurzbeschreibung
@@ -20,6 +20,12 @@ Kurzbeschreibung
     - Wenn sich die Signatur (z. B. body→full, parsed→raw, canonical→none) zwischen Alt/Neu unterscheidet,
       gilt die Note als **geändert** (Einmal-Update, um die neue Signatur zu persistieren).
 
+Robustheit
+----------
+- Rückgaben aus ``make_note_payload`` werden **koerziert** (Tuple, Mapping, Pydantic v1/v2, Objekt) → ``dict``.
+- Bei Nicht-Erfolg präzise Debug-Ausgabe (Typname + kurzer Preview).
+- Defensive Fehlerbehandlung in allen Schritten (Parsing, Chunks, Edges, Upserts).
