# Signed VEX Override Badge (DSSE Status Display)

## Module
Web

## Status
VERIFIED

## Description
SignedOverrideBadgeComponent displaying DSSE badge with verification status, optional expanded details (digest, signer, timestamp, Rekor link), and ASCII-only indicators.

## Implementation Details
- **Feature directory**: `src/Web/StellaOps.Web/src/app/features/triage/components/signed-override-badge/`
- **Components**:
  - `signed-override-badge` (`src/Web/StellaOps.Web/src/app/features/triage/components/signed-override-badge/signed-override-badge.component.ts`)
- **Source**: SPRINT_20260112_004_FE_risk_line_runtime_trace_ui.md

## 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 badge/chip renders with correct status color and label
  - [ ] Verify the badge updates reactively when underlying data changes
  - [ ] Verify tooltip or popover shows additional detail on hover
- **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
- Verified on 2026-02-11 via `docs/qa/feature-checks/runs/web/signed-vex-override-badge/run-001/`.
- Tier 0 confirmed signed-override component/export/test assets and key DSSE status symbol wiring.
- Tier 1 passed focused Angular behavior regression (13 files / 59 tests) and `npm run build`.
- Tier 2 validated badge trust-state rendering, expanded DSSE/Rekor details, and explicit unsigned-state behavior.
