## Conclusion

🎉 **Tier 1 & Tier 2 E2E test suites are COMPLETE and PRODUCTION-READY!**  
🔄 **Tier 3 E2E test suite implementation IN PROGRESS (43% complete)!**

All 21 core scenarios (8 Tier 1 + 13 Tier 2) are validated with comprehensive tests. Tier 3 implementation is progressing well with 9 scenarios completed (26 tests), focusing on:
- Security validation (secret injection, RBAC)
- HTTP runner functionality
- Parameter validation
- Edge cases (past date timers, multiple rules)

**Tier 1 & 2 Coverage:**
- Happy paths
- Error conditions
- Security boundaries
- Performance characteristics
- Workflow orchestration
- Human-in-the-loop approvals
- Retry policies

**Tier 3 Coverage (In Progress):**
- Secret injection security (HIGH priority)
- RBAC enforcement
- HTTP runner (REST API calls)
- Parameter validation
- Edge case handling (past dates, concurrent timers)
- Advanced webhook behavior (multiple rules, criteria filtering)
- Timer lifecycle (cancellation, resume)
- Multi-tenant pack isolation

**Run the tests:**
```bash
# All tests (Tier 1 + Tier 2 + Tier 3)
cd tests && pytest e2e/ -v

# Tier 3 tests only
cd tests && pytest e2e/tier3/ -v

# Security tests across all tiers
cd tests && pytest -m security -v

# HTTP runner tests
cd tests && pytest -m http -v

# Specific Tier 3 test file
cd tests && pytest e2e/tier3/test_t3_20_secret_injection.py -v
```

**Achievements Unlocked**: 
- 🏆 Complete Tier 1 E2E Test Coverage (8 scenarios, 33 tests)
- 🏆 Complete Tier 2 E2E Test Coverage (13 scenarios, 37 tests)
- 🔐 High-Priority Security Tests (Secret injection, RBAC)
- 🌐 HTTP Runner Validation (GET, POST, Auth, Errors)
- 🎯 Rule Criteria Filtering (equality, numeric, complex logic)
- ⏱️ Timer Management (cancellation, concurrent timers)
- 🔒 Multi-Tenant Pack Isolation
- 🎯 96 Total Test Functions Across 19,000+ Lines of Code
