Description

Interactive CSS Grid heatmap showing vendor backport patch coverage across fleet with drill-down to function-level breakdown and paginated affected images. Three API endpoints: aggregated coverage, function-level details, and matching images.

Implementation Details

Feature directory: src/Web/StellaOps.Web/src/app/features/binary-index/
Components:
- binary-index-ops (src/Web/StellaOps.Web/src/app/features/binary-index/binary-index-ops.component.ts)
- patch-map (src/Web/StellaOps.Web/src/app/features/binary-index/patch-map.component.ts)
Verification harness:
- src/Web/StellaOps.Web/src/tests/binary_index/patch-map.component.spec.ts
Source: SPRINT_20260103_001_FE_preset_pills_patch_map.md

E2E Test Plan

Setup:
- Log in with a user that has appropriate permissions
- Navigate to /analyze/patch-map
- Ensure test data exists (scanned artifacts, SBOM data, or seed data as needed)
Core verification:
- Verify the component renders correctly with sample data
- Verify interactive elements respond to user input
- Verify data is fetched and displayed from the correct API endpoints
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)
