## Coverage Analysis
558+
559+
### Test Implementation Characteristics
560+
561+
The test suite implements several design patterns worth noting:
562+
563+
1. Dual language implementation (Rust and C++) ensures API parity across both ecosystems
564+
2. Uses actual lifecycle and health monitoring APIs from `@score_lifecycle_health` rather than mocks
565+
3. Three-layer architecture separates Python orchestration from Rust/C++ implementation
566+
4. Tests function without requiring a running Launch Manager daemon (graceful degradation)
567+
5. Structured logging differs by language: JSON via `tracing` for Rust, plain text for C++
568+
569+
### Technical Observations
570+
571+
**API Integration Approach:**
572+
573+
The tests validate API signatures and integration patterns rather than end-to-end daemon behavior. When no daemon is present, lifecycle client calls return empty results (C++) or `false` (Rust) without panicking. This allows tests to verify that application code correctly uses the lifecycle APIs.
574+
575+
**OCI Compliance Coverage:**
576+
577+
Requirement `feat_req__lifecycle__oci_compliant` (OCI Specification v1.2.0) is tested through `test_configuration_management.py` via the `runtime_config_compat` test. This test validates runtime configuration compliance with OCI standards. Additional documentation could clarify the specific OCI v1.2.0 features validated.
578+
579+
### Potential Enhancements
580+
581+
1. **Requirement Traceability**: Adding requirement IDs as pytest markers would enable automated coverage reporting:
582+
583+
```python
584+
@pytest.mark.requirement("feat_req__lifecycle__launch_support")
585+
def test_process_launching_rust(self, rust_scenario):
586+
...
587+
```
588+
589+
2. **Coverage Automation**: Generate machine-readable coverage reports linking tests to requirements for CI/CD integration
590+
591+
3. **Daemon Integration**: The current approach focuses on API integration. Future work could add tests against a running Launch Manager daemon to validate supervision, recovery, and state management behavior
592+
593+
4. **OCI Compliance Documentation**: Explicitly document which OCI v1.2.0 specification sections are validated by `runtime_config_compat`
594+
595+
## Summary
596+
597+
This test suite covers 85 of 92 lifecycle requirements (92% coverage) and validates API integration patterns for both Rust and C++ implementations. The tests verify that applications can correctly call lifecycle management APIs and integrate with the S-CORE lifecycle framework. The test architecture enables running without a daemon, making tests suitable for CI environments where full daemon infrastructure may not be available.
