+# Delta for grafana access control
+
+## ADDED Requirements
+
+### Requirement: Read-only Grafana user for Vinogorod IT
+
+Grafana MUST provide a read-only account for the Vinogorod IT department:
+login `it@vinogorod.ru`, role `Viewer`, in the default organization (orgId 1).
+The account MUST NOT be able to create, edit, or delete dashboards,
+datasources, or settings.
+
+#### Scenario: User exists with Viewer role
+- GIVEN the admin has created the user `it@vinogorod.ru` in the Grafana UI
+- WHEN the user logs in with the shared password
+- THEN authentication succeeds (Basic auth `/api/user` → HTTP 200)
+- AND the organization role is `Viewer` (`/api/orgs/1/users` → role "Viewer")
+
+#### Scenario: Unknown credentials rejected
+- GIVEN the read-only user `it@vinogorod.ru`
+- WHEN a request is made with a wrong password
+- THEN the API returns HTTP 401
+
+#### Scenario: Read-only enforced
+- GIVEN the user `it@vinogorod.ru` is logged in as `Viewer`
+- WHEN the user attempts a privileged operation (e.g. `POST /api/users`,
+  modify datasources)
+- THEN the request is rejected (HTTP 403/404)
+
+### Requirement: No admin rights for IT user
+
+The IT read-only account MUST NOT have admin or editor rights; only viewing
+of dashboards and logs is permitted.
+
+#### Scenario: Role is not elevated
+- GIVEN the user `it@vinogorod.ru`
+- WHEN checking its org role and admin flag (`/api/user` + `/api/orgs/1/users`)
+- THEN role is `Viewer` and `isGrafanaAdmin` is false
