# VEX Conflict Studio (Visual VEX Conflict Resolution)

## Module
Web

## Status
IMPLEMENTED

## 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-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`)
  - `vex-conflict-studio` (`src/Web/StellaOps.Web/src/app/features/vex-studio/vex-conflict-studio.component.ts`)
- **Source**: Feature matrix scan

## 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)
