Role-Based Access Control (RBAC) in Vectors

In most companies, access control was built for files, folders, and application screens. A person opens a document, and the system checks whether they may. Retrieval-augmented generation changes this. Documents are split into chunks, converted to embeddings, and stored in a vector or graph database. A question arrives, the nearest chunks come back, and the model writes an answer.
