+# Triage Queue for High-Impact Unknowns
+
+## Module
+Web
+
+## Status
+VERIFIED
+
+## Description
+Prioritized triage queue component for high-impact findings with deterministic ranking, multiple sort modes, queue item lifecycle actions, and auto-advance semantics.
+
+## 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`)
+- **Related models/services**:
+  - `Vulnerability` contract (`src/Web/StellaOps.Web/src/app/features/triage/services/vulnerability-list.service.ts`)
+  - triage component exports (`src/Web/StellaOps.Web/src/app/features/triage/components/index.ts`)
+- **Behavior coverage**:
+  - `src/Web/StellaOps.Web/src/tests/triage/triage-queue-for-high-impact-unknowns.behavior.spec.ts`
+- **Source**: Feature matrix scan
+
+## E2E Test Plan
+- **Setup**:
+  - [ ] Log in with a user that has appropriate permissions
+  - [ ] Navigate to triage workspace where the queue component is rendered
+  - [ ] Ensure vulnerability findings data exists for queue ranking
+- **Core verification**:
+  - [ ] Verify queue loads and highest-priority findings appear first
+  - [ ] Verify triage actions (`triaged`, `deferred`, `skipped`) update queue state and progress
+  - [ ] Verify auto-advance behavior and manual jump to upcoming items
+- **Edge cases**:
+  - [ ] Verify deterministic ordering when priority and sort keys tie
+  - [ ] Verify undo lifecycle for recently triaged items
+  - [ ] Verify keyboard/accessibility semantics for action controls

+## Verification
+- Run ID: `docs/qa/feature-checks/runs/web/triage-queue-for-high-impact-unknowns/run-001/`
+- Date (UTC): 2026-02-11
+- Tier 0: PASS (source/symbol verification for triage queue component, vulnerability model contract, and new behavior harness).
+- Tier 1: PASS (`npm run test` focused suite: 21 files / 103 tests; `npm run build` passed with known baseline warnings).
+- Tier 2: PASS (behavioral verification of high-impact ranking, deterministic sort tie-breakers, triage lifecycle events, auto-advance/undo flows, and ASCII-safe operator labels).
