+# Operator/Auditor mode toggle
+
+## Module
+Web
+
+## Status
+VERIFIED
+
+## Description
+View mode service, toggle component, and operator-only/auditor-only directives implement two-mode UI with different default levels of detail.
+
+## Implementation Details
+- **Feature directories**:
+  - `src/Web/StellaOps.Web/src/app/core/services/`
+  - `src/Web/StellaOps.Web/src/app/shared/components/view-mode-toggle/`
+  - `src/Web/StellaOps.Web/src/app/shared/directives/`
+- **Components**:
+  - `view-mode-toggle` (`src/Web/StellaOps.Web/src/app/shared/components/view-mode-toggle/view-mode-toggle.component.ts`)
+- **Services**:
+  - `view-mode.service` (`src/Web/StellaOps.Web/src/app/core/services/view-mode.service.ts`)
+- **Directives**:
+  - `stellaOperatorOnly` (`src/Web/StellaOps.Web/src/app/shared/directives/operator-only.directive.ts`)
+  - `stellaAuditorOnly` (`src/Web/StellaOps.Web/src/app/shared/directives/auditor-only.directive.ts`)
+- **Verification harness**:
+  - `src/Web/StellaOps.Web/src/tests/workspaces/operator-auditor-mode-toggle.spec.ts`
+- **Source**: SPRINT_20260211_006_FE_web_feature_verification_batch24
+
+## E2E Test Plan
+- **Setup**:
+  - [ ] Log in with a user that has appropriate permissions
+  - [ ] Navigate to a page that includes mode toggle and role-gated sections
+  - [ ] Ensure test data exists (scanned artifacts, SBOM data, or seed data as needed)
+- **Core verification**:
+  - [ ] Verify operator mode renders operator-only content
+  - [ ] Verify mode switch to auditor updates role-gated content
+  - [ ] Verify selected mode persists across user interactions
+- **Edge cases**:
+  - [ ] Verify graceful handling when browser storage is unavailable
+  - [ ] Verify responsive layout at different viewport sizes
+  - [ ] Verify accessibility (keyboard navigation, screen reader labels, ARIA attributes)
