I'm reviewing this PR for E2E test coverage as the E2E coverage bot.

Todo List

• Dismiss any stale REQUEST_CHANGES reviews from myself (none found)
• Identify what changed (git diff) - Found new app/onboarding/page.tsx route
• Run mechanical coverage check (2 issues found)
• Read current coverage state (coverage.json and COVERAGE.md)
• Apply decision logic and post appropriate GitHub review

Coverage Issues Detected

Issue 1: Coverage Regression

• Checkpoint count decreased from 412 to 403 (−9 checkpoints)
• This indicates test coverage was removed without replacement

Issue 2: Missing E2E Coverage

• New route app/onboarding/page.tsx has no E2E journey coverage
• This is a user-facing route that requires testing

Analysis: This falls under CASE A - New route added but NO new e2e spec and NO coverage update.

❌ E2E Coverage Required

This PR adds new routes but does not include e2e journey tests or coverage updates.

Missing coverage for:

• app/onboarding/page.tsx - New onboarding route needs journey coverage

Additional Issue:

• Coverage regression detected: checkpoint count decreased from 412 to 403 (−9 checkpoints)
• Removing test coverage is not allowed without replacement

To fix:

1. Add a journey spec in e2e/journeys/ testing the onboarding feature
2. In e2e/coverage.json: add the route to sourceFiles[] and add checkpoint entries with "status": "covered"
3. In e2e/COVERAGE.md: add matching [x] checkpoint lines
4. Restore the 9 missing checkpoints or justify their removal

Coverage check output:

Coverage REGRESSION: checkpoints decreased from 412 to 403 (−9)
NEW ROUTES without E2E journey coverage:
  app/onboarding/page.tsx

Run locally to verify:

node e2e/scripts/check-journey-coverage.mjs --all
