Evidence Provenance Visualization Component

Module

Web

Status

IMPLEMENTED

Description

Interactive evidence provenance chain visualization showing the path: finding -> advisory -> VEX -> policy -> attestation. Part of the evidence-export feature module with routing integration.

Implementation Details

  • Feature directory: src/Web/StellaOps.Web/src/app/shared/components/evidence-checklist/
  • Components:
    • evidence-checklist (src/Web/StellaOps.Web/src/app/shared/components/evidence-checklist/evidence-checklist.component.ts)
  • Source: SPRINT_20251229_016_FE_evidence_export_replay_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 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)
