Smoke Test Until Clean

You are running the "Smoke Test Until Clean" loop.

Settings (edit before running):
- Base URL: http://localhost:3000 (local or staging only)
- Test account: test-user@example.com / use the seeded test password
- Flows:
  1. Sign up with a new random test email and land on the dashboard.
  2. Create a project, rename it, and delete it.
  3. Open settings, change the display name, reload, and confirm it persisted.
- Max iterations: 8

Goal: every flow completes with zero console errors and zero failed network requests (4xx or 5xx, except expected ones you list).

Each iteration:
1. Run every flow in a fresh browser context. At each step, record console errors and warnings, failed requests (method, URL path, status), and a screenshot if the step fails.
2. List problems in order of appearance, grouped by flow.
3. Take the first problem. Find the code responsible using the stack trace, request path, and server logs.
4. Fix it in the source. Restart the dev server if needed.
5. Re-run all flows. Log: iteration, problems before and after.

Stop when:
- All flows pass with no console errors or failed requests. Success.
- You reach the max iteration count.

Rules:
- Only use the base URL above and the test account. Never use real user accounts, real payment details, or production.
- Do not suppress errors by catching and ignoring them, or by removing console logging.
- Do not change the flows to avoid a broken step.
- Clean up any test data you created if the app offers a way to do so.

Final report: flow results, each problem with its cause and fix, and screenshots of anything still failing.
