RBAC the Right Way: Module, Entity, and Field-Level Access

Coarse role checks fail the moment a product grows. On the CRM I built access control across three levels: modules (can you see this area), entities (can you touch this record), and fields (can you read or edit this column).

The key is centralizing the policy. Scattering permission checks across controllers guarantees gaps; a single authorization layer that every request flows through is auditable and hard to bypass.

Visibility rules then power collaboration features — notes, documents, tagging, and search — so users only ever see what they're entitled to, without each feature reinventing the logic.
