# Deployment Detail with Workflow DAG Visualization

## Module
Web

## Status
VERIFIED

## Description
Deployment detail page with workflow DAG visualization showing deployment step execution, artifact promotion flow, and gate evaluation results.

## Implementation Details
- **Feature directory**: `src/Web/StellaOps.Web/src/app/features/deployments/`
- **Routes**: `deployments.routes.ts`
- **Components**:
  - `deployment-detail-page` (`src/Web/StellaOps.Web/src/app/features/deployments/deployment-detail-page.component.ts`)
  - `deployments-list-page` (`src/Web/StellaOps.Web/src/app/features/deployments/deployments-list-page.component.ts`)
- **Source**: SPRINT_20260118_008_FE_environments_deployments.md

## E2E Test Plan
- **Setup**:
  - [ ] Log in with a user that has appropriate permissions
  - [ ] Navigate to `/release-orchestrator`
  - [ ] Ensure test data exists (scanned artifacts, SBOM data, or seed data as needed)
- **Core verification**:
  - [ ] Verify the visualization renders correctly with sample data
  - [ ] Verify interactive elements (hover tooltips, click-to-drill-down) work
  - [ ] Verify the visualization handles empty/minimal data gracefully
- **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)
