E2E TEST CREATION PLAN
================================================================================

10 Critical User Journeys to Add:

CRITICAL (Must Have):
1. Create Project → Add Items → Build Graph → Verify WebSocket
2. OAuth Login → Create Project → Verify Authenticated State

HIGH PRIORITY:
3. Search → Filter → Update Items → Verify Index Updated
4. Graph Analysis → Dependencies → Impact → Verify Results
9. Security: CSRF/XSS/Rate Limit/Auth Headers

MEDIUM PRIORITY:
5. Temporal Workflow: Create → Execute → Verify Results
6. Real-time Sync: WebSocket → Item Update → Event Received
7. Error Recovery: Network Failure → Retry → Eventual Consistency
10. Accessibility: Keyboard Navigation, Screen Reader Support

LOW PRIORITY:
8. Performance: Bulk Import 1M items → Index → Query (<1s)

Creation Effort: 40 minutes (10 tests, ~4 min each including setup)

SUCCESS CRITERIA & METRICS
================================================================================

Primary Targets:
  ✓ Reduce test count: 3,914 → 2,900 (-26%)
  ✓ Rebalance pyramid: 91/9/0.3 → 70/20/10
  ✓ Improve execution: 180s → 130s (-28%)
  ✓ Add E2E coverage: 0 → 10 critical journeys
  ✓ Zero test redundancy: 683 → 0 duplicate tests

Secondary Targets:
  ✓ Reduce test files: 299 → 270 (-10%)
  ✓ Optimize avg tests/file: 13.1 → 10.7 (-18%)
  ✓ Improve code reviews: +30% clarity
  ✓ Reduce test maintenance: -50% burden
  ✓ Eliminate duplicate test names: 16 → 0

Verification Methods:
  1. Count tests by level (unit/integration/E2E)
  2. Compare execution time before/after
  3. Verify no test failures post-consolidation
  4. Measure coverage maintained or improved
  5. Confirm all 10 E2E journeys pass
  6. Review code diffs for consolidation correctness

================================================================================
RISK ASSESSMENT & MITIGATION
================================================================================

Risk 1: Consolidation removes important tests
Probability: MEDIUM
Severity: HIGH
Mitigation: Pre-consolidation audit of all tests with scenario documentation,
            run tests post-consolidation to verify all pass, compare coverage
            reports before/after, keep git history to recover if needed

Risk 2: E2E tests fail or are flaky
Probability: MEDIUM
Severity: MEDIUM
Mitigation: Elevate tests in phases (10 tests at a time), verify each batch
            before continuing, use full stack (no mocks), environment flags
            for optional infrastructure in CI

Risk 3: Test pyramid logic breaks
Probability: LOW
Severity: MEDIUM
Mitigation: Monitor execution time (should improve, not degrade), verify
            critical paths covered at each level, E2E tests must use real services

Risk 4: Developer resistance to changes
Probability: MEDIUM
Severity: LOW
Mitigation: Provide clear rationale with metrics, show faster execution times,
            document merge strategy before execution, use git to preserve blame

Risk Assessment Summary:
  Overall Risk Level: MEDIUM
  Confidence Level: HIGH
  Recommendation: PROCEED WITH PHASED APPROACH
