**Deliverables**: Comprehensive documentation ✓ (ARCHITECTURE.md, INTEGRATION_GUIDE.md, SECURITY_GUIDE.md, MIGRATION_GUIDE.md created; README.md and milestone.md updated with Phase 7 summaries)

#### 7.6 Integration Testing (Weeks 51-52)
- [ ] Cross-module end-to-end workflow tests (v2.x → v3.x → FHIR pipelines)
- [ ] HL7 v2.x parsing and building round-trip integration tests
- [ ] HL7 v3.x CDA document lifecycle integration tests
- [ ] FHIR resource CRUD and Bundle transaction integration tests
- [ ] Cross-version interoperability tests (v2/v3/FHIR coexistence)
- [ ] Persistence and archival integration tests (message store → retrieve → export)
- [ ] Security framework integration tests (encrypt → sign → verify → decrypt pipeline)
- [ ] Error recovery and fault tolerance integration tests across modules
- [ ] Mock server/client integration tests for MLLP and REST transports
- [ ] CLI tool integration tests (end-to-end command execution with real data)

**Deliverables**: Comprehensive integration test suite validating cross-module workflows, data consistency across HL7 versions, and end-to-end system behavior

#### 7.7 Performance Testing (Weeks 53-54)
- [ ] HL7 v2.x message parsing throughput benchmarks (target: >10,000 msg/s)
- [ ] HL7 v3.x XML parsing and CDA document processing benchmarks
- [ ] FHIR JSON/XML serialization and deserialization benchmarks
- [ ] Memory profiling for large message volumes (1,000+ concurrent messages)
- [ ] Concurrent parsing scalability tests (multi-core utilization)
- [ ] Network transport performance tests (MLLP framing, REST latency, TLS overhead)
- [ ] Object pool and string interning efficiency benchmarks
- [ ] Streaming API performance for large documents and Bundles
- [ ] Latency profiling with p50/p95/p99 percentile measurements
- [ ] Regression baseline comparison tests to detect performance degradation

**Deliverables**: Complete performance benchmark suite with throughput, latency, memory, and scalability metrics across all modules; regression baselines for continuous monitoring
