+# Triage Queue for High-Impact Unknowns
+
+## Module
+Web
+
+## Status
+IMPLEMENTED
+
+## Description
+Triage queue UI component (`triage-queue.component.ts`) with prioritized vulnerability queue, priority scoring, sort modes (priority/severity/age/epss), queue item lifecycle, and auto-advance after triage decision. Backend scoring primitives in the Determinization library feed queue ranking.
+
+## Implementation Details
+- **Feature directory**: `src/Web/StellaOps.Web/src/app/features/triage/components/triage-queue/`
+- **Components**:
+  - `triage-queue` (`src/Web/StellaOps.Web/src/app/features/triage/components/triage-queue/triage-queue.component.ts`)
+- **Source**: Feature matrix scan
+
+## E2E Test Plan
+- **Setup**:
+  - [ ] Log in with a user that has appropriate permissions
+  - [ ] Navigate to the relevant page/section where this feature appears
+  - [ ] Ensure test data exists (scanned artifacts, SBOM data, or seed data as needed)
+- **Core verification**:
+  - [ ] Verify the triage list loads with findings/items to review
+  - [ ] Verify triaging actions (accept, dismiss, override) update item status
+  - [ ] Verify keyboard shortcuts work for rapid triage navigation
+- **Edge cases**:
+  - [ ] Verify graceful handling when backend API is unavailable (error state)
+  - [ ] Verify responsive layout at different viewport sizes
+  - [ ] Verify accessibility (keyboard navigation, screen reader labels, ARIA attributes)
