## Module
Web

## Status
IMPLEMENTED

## Description
Web gateway client for Graph Platform APIs with tile streaming, search, path queries, export (GraphML/NDJSON/CSV/PNG/SVG), asset snapshots, adjacency queries, and AOC overlay pass-through, all with tenant scoping and RBAC.

## E2E Test Plan
- **Setup**:
  - [ ] Log in with a user that has appropriate permissions
  - [ ] Navigate to `/graph`
  - [ ] 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)
