Description

There are no end-to-end tests. Adding Playwright would catch integration regressions that unit tests miss, especially around the Freighter wallet flow and SSE live updates.

What Needs to Happen

• Add Playwright to the frontend project
• Create frontend/e2e/stream-lifecycle.spec.ts:
  • Connect wallet (mock Freighter in CI)
  • Navigate to dashboard and see stream list
  • Open stream creation wizard and fill all steps
  • Verify stream appears in dashboard
  • Pause and resume the stream
  • Cancel the stream and confirm status change
• Add E2E job to CI after the frontend build job
• Upload Playwright HTML report as artifact on failure
• Cache Playwright browser binaries

Files

• frontend/e2e/stream-lifecycle.spec.ts (create)
• .github/workflows/ci.yml

Acceptance Criteria

• E2E tests run on every PR
• Report uploaded on failure
• All 6 scenarios pass in headless Chromium
