 You do **not** need to delete `agent-data`; the init service fixes ownership on the existing named volume.
+
+## Human-in-the-loop-Lernen und Web-Knowledge-Base
+
+Der Agent lernt **nicht aus seinen eigenen Entscheidungen**. Im Dashboard kann eine Kategorie eines verarbeiteten Tickets ausdrücklich bestätigt oder korrigiert werden. Diese menschlich bestätigten Beispiele werden in `DATA_DIR/category-learning.json` persistiert und bei ähnlichen Tickets als `confirmed_examples` an das Klassifikationsmodell übergeben. Zusätzlich werden Kategorie-Hinweise aus freigegebenen KB-Keywords und konservativen IT-Semantik-Hinweisen aufgebaut.
+
+Konfiguration:
+
+```env
+LEARNING_ENABLED=true
+LEARNING_MAX_EXAMPLES=500
+LEARNING_EXAMPLES_PER_CATEGORY=5
+```
+
+Das Dashboard enthält außerdem einen CRUD-Editor für interne Knowledge-Einträge. Er ist absichtlich nur bei authentifiziertem Dashboard aktiv:
+
+```env
+WEB_ALLOW_ANONYMOUS=false
+KNOWLEDGE_WEB_EDIT_ENABLED=true
+```
+
+Web-verwaltete Artikel landen **nicht** im statischen `KNOWLEDGE_DIR`, sondern unter `DATA_DIR/knowledge-managed/`. Dadurch kann `knowledge/` weiterhin read-only aus Git/Image gemountet werden. Statische Artikel werden im Web angezeigt, können dort aber nicht überschrieben oder gelöscht werden. Neue bzw. im Web verwaltete Artikel werden nach dem Speichern sofort in den laufenden Such-/RAG-Store aufgenommen; ein Neustart ist nicht nötig.
+
+Für stabilere Structured Outputs sind die empfohlenen Startwerte:
+
+```env
+OLLAMA_NUM_PREDICT=768
+OLLAMA_JSON_RETRIES=1
+```
+
+Bei unvollständigem/ungültigem JSON wird genau einmal erneut eine schema-konforme Antwort angefordert.
+
+### Deployment mit Gitea Container Registry unter Linux
+
+Für ein bereits in Gitea gebautes Image ist `docker-compose.registry.yml` vorgesehen; lokal wird nichts gebaut.
+
+```bash
+export AGENT_IMAGE=gitea.example.de/organisation/glpi-ai-agent:latest
+mkdir -p data knowledge
+sudo chown 65532:65532 data
+# knowledge bleibt absichtlich read-only; Web-KB landet unter data/knowledge-managed/
+docker compose -f docker-compose.registry.yml pull
+docker compose -f docker-compose.registry.yml up -d
+```
+
+Bei neuen Gitea-Builds genügt:
+
+```bash
+docker compose -f docker-compose.registry.yml up -d --pull always
+```

 - Asset lookup paths and filters are operator-controlled and validated where possible against GLPI's generated OpenAPI route list. Field/filter semantics still need Shadow-Mode verification on the real instance.
 - Prefer Uptime Kuma `UPTIME_KUMA_MODE=metrics` for private monitoring. Store `UPTIME_KUMA_API_KEY` as a secret and give the key only the access needed for metrics. `status_page` mode should be used only for information safe to publish on that status page.
 - Do not place passwords, tokens, personal secrets or raw diagnostic dumps into Change/Incident descriptions merely because the agent can read them; relevant text may be passed to the local Ollama model.
+
+## Dashboard-Schreibfunktionen
+
+`KNOWLEDGE_WEB_EDIT_ENABLED=true` darf nicht zusammen mit `WEB_ALLOW_ANONYMOUS=true` verwendet werden; die Konfiguration wird beim Start abgelehnt. Mutierende Dashboard-Endpunkte verlangen zusätzlich den Same-App-Request-Header `X-Requested-With: GLPI-AI-Agent`. Statische Knowledge-Dateien aus `KNOWLEDGE_DIR` bleiben read-only; Web-Inhalte werden ausschließlich unter `DATA_DIR/knowledge-managed/` persistiert.
+
+Kategorie-Lernen ist Human-in-the-loop: Nur eine ausdrückliche Bestätigung/Korrektur im Dashboard wird als Lernbeispiel gespeichert. Der Agent übernimmt seine eigenen KI-Empfehlungen oder automatisch geschriebenen Kategorien niemals selbständig in den Lernbestand.

+LEARNING_ENABLED=true
+LEARNING_MAX_EXAMPLES=500
+LEARNING_EXAMPLES_PER_CATEGORY=5
+
+# Nur bei authentifiziertem Dashboard aktivieren:
+KNOWLEDGE_WEB_EDIT_ENABLED=true
+```
+
+`KNOWLEDGE_DIR` bleibt statisch/read-only. Im Dashboard erzeugte Artikel werden automatisch unter `DATA_DIR/knowledge-managed/` gespeichert. Bestätigte Kategorie-Lernbeispiele liegen in `DATA_DIR/category-learning.json`.
+
+## Gitea-Registry / Linux
+
+Das Image weiterhin in Gitea bauen. Auf dem Zielsystem ist kein lokaler Build erforderlich:
+
+```bash
+export AGENT_IMAGE=gitea.example.de/organisation/glpi-ai-agent:latest
+mkdir -p data knowledge
+sudo chown 65532:65532 data
+docker compose -f docker-compose.registry.yml up -d --pull always
+```
+
+Der statische Ordner `./knowledge` bleibt read-only. Da Web-KB und Lernspeicher unter `./data` liegen, müssen nur die Daten für UID/GID `65532:65532` beschreibbar sein.
+
+## Sicherer Start
+
+Für die ersten Lernläufe empfohlen:
+
+```env
+DRY_RUN=true
+AUTO_CATEGORY=true
+AUTO_REPLY=false
+CATEGORY_CONFIDENCE=0.90
+```
+
+Im Dashboard anschließend Entscheidungen bestätigen/korrigieren. Erst nach genügend beobachteten Tickets Schwellwerte oder Schreibrechte anpassen.
