## 2026-06-12 — E2E tests in CI with existing server

When the QA agent runs and the app is already started (e.g., pre-started in the GitHub Actions job), `npm run e2e` will error with "port 3000 already in use" because `playwright.config.ts` sets `reuseExistingServer: !process.env.CI` — meaning in CI it refuses to reuse. Workaround: run with `CI= npm --prefix app run e2e` to unset the CI flag and allow Playwright to reuse the running server.
