+# VEX Conflict Studio (Visual VEX Conflict Resolution)
+
+## Module
+Web
+
+## Status
+VERIFIED
+
+## Description
+Interactive studio for resolving VEX statement conflicts from multiple sources. Displays conflicting statements with trust weights, merge traces, and K4 lattice visualization. Users can filter/sort conflicts, view merge explanations (`trust_weight`, `freshness`, `lattice_position`), apply manual overrides via a dialog, and remove overrides.
+
+## Implementation Details
+- **Feature directory**: `src/Web/StellaOps.Web/src/app/features/vex-studio/`
+- **Components**:
+  - `vex-conflict-studio` (`src/Web/StellaOps.Web/src/app/features/vex-studio/vex-conflict-studio.component.ts`)
+  - `vex-merge-panel` (`src/Web/StellaOps.Web/src/app/features/vex-studio/components/vex-merge-panel/vex-merge-panel.component.ts`)
+  - `override-dialog` (`src/Web/StellaOps.Web/src/app/features/vex-studio/override-dialog/override-dialog.component.ts`)
+- **Behavior coverage**:
+  - `src/Web/StellaOps.Web/src/tests/vex_studio/vex-conflict-studio.behavior.spec.ts`
+- **Source**: Feature matrix scan and QA deterministic sorting/tracking hardening in Sprint `SPRINT_20260211_031_FE_web_feature_verification_batch41`.
+
+## E2E Test Plan
+- **Setup**:
+  - [ ] Log in with a user that has appropriate permissions
+  - [ ] Navigate to `/triage/artifacts/:artifactId`
+  - [ ] Ensure test data exists (scanned artifacts, SBOM data, or seed data as needed)
+- **Core verification**:
+  - [ ] Verify the editor/studio loads with editable content or empty template
+  - [ ] Verify changes can be saved and persisted
+  - [ ] Verify validation errors are displayed for invalid input
+- **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)
+
+## Verification
+- Run ID: `docs/qa/feature-checks/runs/web/vex-conflict-studio/run-001/`
+- Date (UTC): 2026-02-11
+- Tier 0: PASS (source/symbol verification; added supported behavior harness; hardened deterministic sorting/trackBy semantics and preserved route filter context on override reload).
+- Tier 1: PASS (`npm run test` focused + regression include suite: 34 files / 155 tests; `npm run build` passed with baseline warnings).
+- Tier 2: PASS (conflict loading/sorting/filtering behavior and override reload semantics verified via Angular behavior harness).
