+## Purview Governance for Fabric Copilots og Agenter *(Verified MCP 2026-04)*
+
+Microsoft Purview gir nå governance-dekning for Fabric Copilots og agenter — et nytt område som dekker AI-generert innhold i Fabric-arbeidsmiljøer.
+
+| Funksjonalitet | Beskrivelse |
+|---------------|-------------|
+| **Risk discovery** | Oppdager sensitiv informasjon i prompts og AI-responser i Fabric Copilots |
+| **Audit coverage** | Loggfører AI-interaksjoner (hvem spurte hva, når, hvilken respons) for compliance |
+| **Retention policies** | Beholder og sletter AI-generert innhold etter definerte retention-regler |
+| **eDiscovery** | AI-generert innhold er søkbart og kan inkluderes i juridiske eDiscovery-prosesser |
+
+**Relevans for norsk offentlig sektor:**
+- Offentlige virksomheter som bruker Copilot i Fabric-løsninger må sikre at AI-interaksjoner er sporbare og underlagt arkivlovgivningen
+- Purview gir mulighet for å dokumentere AI-beslutningsprosesser i henhold til Forvaltningslovens krav om begrunnelse
