 Das Polling bleibt immer aktiv und dient als Fallback. Der Webhook-Parser akzeptiert übliche Ticket-ID-Felder sowie Ticket-URLs; prüfe die konkrete Payload deiner GLPI-Webhook-Konfiguration im Shadow Mode.

+### Erklärbare Entscheidungen im Dashboard
+
+Für den Shadow-/Einführungsbetrieb speichert jeder Lauf die **rohe KI-Empfehlung** getrennt von der **Policy-Entscheidung**. Das Modell liefert bei Kategorien nur noch `id` und `confidence`; ein eigenes `change=true/false` gibt es nicht mehr. Ob tatsächlich geändert werden darf, entscheidet ausschließlich Go anhand der aktuellen Kategorie, der bekannten GLPI-Kategorien und `CATEGORY_CONFIDENCE`.
+
+Das Dashboard zeigt deshalb unter anderem:
+
+- aktuelle Kategorie mit ID und Name,
+- von der KI empfohlene Kategorie mit ID und Name,
+- KI-Confidence und konfigurierten Schwellwert,
+- expliziten Entscheidungsgrund wie `category_confidence_below_threshold`, `category_already_correct` oder `category_written`,
+- KI-Empfehlung für Auto-Reply samt Confidence und Reply-Schwellwert,
+- besten Knowledge-Treffer mit Score,
+- den ersten Policy-Blocker für einen Reply, z. B. fehlendes Knowledge, vorhandenes Followup, unvollständigen Kontext oder einen relevanten Incident,
+- die fachliche KI-Begründung separat von den technischen Policy-Codes.
+
+Damit ist auch ein Lauf ohne Schreibaktion nachvollziehbar. Beispiel: „KI empfiehlt Active Directory (#17) mit 82 %, Schwellwert 90 % → nicht geändert“. Die JSON-Details stehen zusätzlich unter `/api/runs?limit=50` zur Verfügung.
