Why does Cross-Platform Document Migration matter for AI governance?

When content from four systems arrives with four permission models, the same person holds different rights depending on which source a document came from — and a retrieval layer evaluating entitlement across that mixture cannot give a consistent answer. The resulting surface is defined by an accident of migration order rather than by policy. Centralpoint reconciles identity and applies one governance dictionary during ingestion regardless of origin, so entitlement is evaluated against a resolved subject and one classification scheme rather than a translation between four.
