Cross-reference the test case list from the plan with implementation results, and verify all cases have been implemented.

**Important:** Refer to the test plan report: {report:01-e2e-coverage-plan.md}

**Verification procedure:**

1. **Cross-reference with test case list (most important)**
   - Check each numbered test case from the plan report one by one
   - Identify the corresponding test file and test name for each case
   - Read the test file to confirm the case is actually tested
   - List any cases without a corresponding test as "unimplemented"
   - REJECT if even one unimplemented case exists

2. **Test quality verification**
   - Does each test correctly verify the intent of the test case?
   - Are assertions appropriate (not just existence checks, but value verification)?
   - Does the mock/fixture usage follow existing patterns?

3. **Test execution verification**
   - Run E2E tests and confirm all tests pass
   - Confirm existing tests are not broken
