+# Eskalationsfunktionen
+
+Die Eskalation ist ein eigenständiger, zeitgesteuerter KI-Lauf. Sie ist von der normalen Ticketversion-Deduplizierung unabhängig und kann deshalb unveränderte Tickets erneut bewerten. Das Modell darf ausschließlich eine strukturierte Empfehlung aus kontrollierten Aktionen und Grundcodes abgeben. Jede Aktion wird anschließend separat durch Go-Regeln geprüft und erhält einen eigenen Schritt im `ActionAudit`.
+
+## Sicherer Betriebsmodus
+
+Empfohlener Einstieg:
+
+```env
+DRY_RUN=true
+ESCALATION_ENABLED=true
+AUTO_ESCALATION=false
+ESCALATION_SCAN_INTERVAL=30m
+ESCALATION_MIN_AGE=4h
+ESCALATION_MIN_INACTIVITY=2h
+ESCALATION_ANALYSIS_TIMEOUT=45s
+GLPI_ESCALATION_FILTER=status.id==1
+```
+
+`ESCALATION_ENABLED=true` startet Scheduler und KI-Analyse. `AUTO_ESCALATION=false` hält alle Aktionen im Shadow Mode. Ein Live-Write ist nur möglich, wenn zusätzlich `AUTO_ESCALATION=true` und `DRY_RUN=false` gelten.
+
+## Deterministische Belege
+
+Vor dem Modellaufruf berechnet der Agent selbst:
+
+- Ticketalter seit `date_creation`
+- Inaktivitätsdauer seit dem letzten nicht-agentischen Followup; sie ist nur für den Grund `no_human_response` ein blockierendes Gate
+- fehlende Zuweisung
+- SLA-Frist aus `time_to_resolve`
+- SLA-Verletzung oder Risiko innerhalb `ESCALATION_SLA_RISK_WINDOW`
+- relevantesten Major-Incident-Kandidaten oberhalb `ESCALATION_MAJOR_INCIDENT_MIN_RELEVANCE`
+
+Diese Werte werden im Input-Snapshot unter `evidence` gespeichert. Das Modell darf sie nicht erfinden oder überschreiben.
+
+## Verfügbare Aktionen
+
+### `raise_priority`
+
+Erhöht die aktuelle GLPI-Priorität deterministisch um genau eine Stufe. Herabstufungen und Werte oberhalb 6 sind ausgeschlossen.
+
+Erforderlich:
+
+```env
+ESCALATION_ALLOWED_ACTIONS=none,raise_priority
+```
+
+### `assign_second_level`
+
+Fügt die konfigurierte Second-Level-Gruppe zu den vorhandenen Ticketzuweisungen hinzu. Vorhandene Gruppen bleiben erhalten. Zulässig ist die Aktion nur bei einem operativen Eskalationsgrund wie fehlender Reaktion, fehlender Zuweisung, SLA-Risiko, fachlicher Frist oder fehlender Ausweichmöglichkeit.
+
+```env
+ESCALATION_SECOND_LEVEL_GROUP_ID=42
+ESCALATION_ALLOWED_ACTIONS=none,assign_second_level
+```
+
+### `assign_security_team`
+
+Fügt die konfigurierte Security-Gruppe hinzu. Die Policy akzeptiert die Aktion ausschließlich zusammen mit `security_incident_suspected`.
+
+```env
+ESCALATION_SECURITY_GROUP_ID=51
+ESCALATION_ALLOWED_ACTIONS=none,assign_security_team
+```
+
+### `notify_service_owner`
+
+Bindet einen Service Owner über eine GLPI-Gruppe, einen GLPI-Benutzer, einen Webhook oder eine Kombination daraus ein. Die Aktion ist erst ab `ESCALATION_SERVICE_OWNER_MIN_LEVEL` zulässig.
+
+```env
+ESCALATION_SERVICE_OWNER_MIN_LEVEL=2
+ESCALATION_SERVICE_OWNER_GROUP_ID=61
+ESCALATION_SERVICE_OWNER_USER_ID=62
+ESCALATION_WEBHOOK_URL=https://internal.example/escalations
+ESCALATION_WEBHOOK_BEARER_TOKEN=...
+ESCALATION_WEBHOOK_ALLOW_INSECURE_HTTP=false
+ESCALATION_ALLOWED_ACTIONS=none,notify_service_owner
+```
+
+Das Bearer-Token wird nicht über Status- oder Diagnose-API ausgegeben. Der Webhook erhält einen `Idempotency-Key`-Header und ein JSON-Objekt mit Ticket-ID, Stufe, Aktion, Ziel, Confidence, Grundcodes und Begründung.
+
+### `link_major_incident`
+
+Verknüpft das Ticket mit dem deterministisch relevantesten Major-Incident-Kandidaten. Die Policy verlangt:
+
+- `major_incident_candidate`
+- aktivierten Major-Incident-Kontext
+- einen Kandidaten oberhalb des Relevanzschwellwerts
+- einen ausdrücklich konfigurierten GLPI-Linkadapter
+
+```env
+CONTEXT_ENABLED=true
+MAJOR_INCIDENTS_ENABLED=true
+ESCALATION_MAJOR_INCIDENT_MIN_RELEVANCE=0.50
+ESCALATION_ALLOWED_ACTIONS=none,link_major_incident
+GLPI_ESCALATION_ITIL_LINK_PATH=/INSTALLATIONSSPEZIFISCHER/PFAD/{{ticket_id}}
+GLPI_ESCALATION_ITIL_LINK_BODY={"source":{"id":{{ticket_id}}},"target":{"id":{{major_incident_id}}}}
+```
+
+Pfad und JSON-Body müssen anhand des API-Vertrags der konkreten Installation gesetzt werden. Ohne beide Werte wird die Aktion nicht an das Modell angeboten und im Live-Modus verweigert die Konfigurationsprüfung den Start.
+
+### `request_manager_review`
+
+Fordert ab `ESCALATION_MANAGER_REVIEW_MIN_LEVEL` eine Management-Prüfung an. Als Ziel können Gruppe, Benutzer und/oder Webhook konfiguriert werden.
+
+```env
+ESCALATION_MANAGER_REVIEW_MIN_LEVEL=3
+ESCALATION_MANAGER_REVIEW_GROUP_ID=71
+ESCALATION_MANAGER_REVIEW_USER_ID=72
+ESCALATION_ALLOWED_ACTIONS=none,request_manager_review
+```
+
+## Private Eskalationsnotizen
+
+Mit `ESCALATION_ADD_PRIVATE_FOLLOWUP=true` schreibt jede ausgeführte Aktion einen privaten GLPI-Followup. Die Texte sind operatorseitige Templates, nicht frei vom Modell erzeugte Antworten.
+
+Verfügbare Variablen:
+
+- `{{ticket_id}}`
+- `{{ticket_name}}`
+- `{{level}}`
+- `{{action}}`
+- `{{reason}}`
+- `{{reason_codes}}`
+- `{{major_incident_id}}`
+- `{{major_incident_name}}`
+- `{{major_incident_score}}`
+
+Konfigurierbare Templates:
+
+```env
+ESCALATION_SECOND_LEVEL_NOTE=...
+ESCALATION_SECURITY_NOTE=...
+ESCALATION_SERVICE_OWNER_NOTE=...
+ESCALATION_MAJOR_INCIDENT_NOTE=...
+ESCALATION_MANAGER_REVIEW_NOTE=...
+```
+
+## GLPI-Zuweisungsadapter
+
+Die Namen der Ticketfelder können installationsabhängig sein. Der Agent unterstützt zwei Payload-Formen:
+
+```env
+GLPI_ESCALATION_GROUP_PATCH_FIELD=assigned_groups
+GLPI_ESCALATION_USER_PATCH_FIELD=assigned_users
+```
+
+Pluralfelder erhalten eine Liste von `{ "id": ... }` und sind der empfohlene Adapter, wenn vorhandene Zuweisungen erhalten bleiben sollen. Für die installationsabhängigen Singularfelder `group`, `group_tech`, `user` und `user_tech` wird nur ein einzelnes `{ "id": ... }` gesendet; deren Ergänzungs- oder Ersetzungsverhalten muss deshalb besonders sorgfältig gegen die konkrete GLPI-API geprüft werden. Vor Live-Aktivierung ist ein Shadow- und Testticket-Lauf zwingend.
+
+## Mehrere Aktionen pro Lauf
+
+Das Modell kann höchstens drei Aktionen empfehlen. Jede Aktion besitzt:
+
+- eigenes Ziel
+- eigene Policy-Checks
+- eigenen Entscheidungscode
+- eigenen Idempotenzschlüssel
+- eigenen Audit-Schritt mit `proposed`, `executed`, `dry_run`, `before`, `after`, `result` und `error`
+
+Eine Aktion wird nicht freigegeben, nur weil eine andere Aktion im selben Lauf zulässig ist. Beispielsweise kann `assign_second_level` akzeptiert und `assign_security_team` wegen fehlendem Sicherheitsgrund blockiert werden.
+
+## Idempotenz
+
+Erfolgreiche Live-Schritte werden separat in `DATA_DIR/state-index.json` gespeichert. Ein Schlüssel enthält Ticket, Stufe, Aktion und Ziel, zum Beispiel:
+
+```text
+ticket=20;level=2;action=assign_second_level;target=group:42
+```
+
+Damit kann eine andere Aktion derselben Stufe noch ausgeführt werden, während eine bereits erfolgreiche identische Aktion nicht erneut geschrieben wird. Historische alte Schlüssel im Format `ticket=20;level=2` bleiben für `raise_priority` kompatibel.
+
+## Empfohlene stufenweise Freigabe
+
+1. Nur `raise_priority` im Shadow Mode beobachten.
+2. `assign_second_level` mit einer Testgruppe ergänzen.
+3. Security-Zuweisung anhand gezielter Testtickets prüfen.
+4. Service-Owner und Management zunächst nur per Webhook oder Testziel validieren.
+5. Major-Incident-Link erst nach erfolgreichem Test des installationsspezifischen Linkadapters aktivieren.
+6. Erst danach `AUTO_ESCALATION=true` und schließlich `DRY_RUN=false` setzen.

+- Jede Eskalationsaktion besitzt eine eigene Allowlist-, Ziel-, Grundcode-, Stufen- und Idempotenzprüfung.
