 - Define hierarchical area structures per site.
 - Parent-child area relationships.
 - Assign areas when managing instances.

 Every incoming message carries the authenticated user's identity and roles. The ManagementActor enforces the same role-based authorization rules as the Central UI:
 
-- **Admin** role required for: site management, area management, API key management, role mapping management, scope rule management, system configuration.
+- **Admin** role required for: site management, API key management, role mapping management, scope rule management, system configuration.
 - **Design** role required for: template authoring (including template member management: attributes, alarms, native alarm sources, scripts, compositions), shared scripts, external system definitions, database connection definitions, notification lists, inbound API method definitions.
 - **Deployment** role required for: instance management (including instance alarm overrides and native alarm source overrides), deployments, debug view, debug snapshot, parked message queries, site event log queries. Site scoping is enforced for site-scoped Deployment users.
+- **Any of Design / Deployment** required for: area management (`CreateAreaCommand` / `UpdateAreaCommand` / `DeleteAreaCommand`). Areas are authored both in the Designer tooling and inside the Central UI Deployment Topology workflow (`Topology.razor` is `RequireDeployment`), so either role qualifies — enforced as an any-of gate (arch-review C6). Administrator is not implicitly included.
 - **Operator** role required for: submitting a secured write (`SubmitSecuredWriteCommand`).
 - **Verifier** role required for: approving / rejecting a secured write (`ApproveSecuredWriteCommand` / `RejectSecuredWriteCommand`). The no-self-approval rule (`Operator ≠ Verifier`) is enforced in the handler, independent of the role check.
 - **Any of Operator / Verifier / Administrator** required for: listing / querying secured writes (`ListSecuredWritesCommand`). Read-only, but the history exposes process-sensitive tag values, so it is gated any-of rather than open to every authenticated user (arch-review UA1). Enforced as an any-of gate (`GetRequiredRoles` returns the permitted set; the caller must hold at least one).
