-## 🎉 Phase 3 Achievements (October 2025)
-
-**NetworkActor Comprehensive Testing Complete!**
-
-Phase 3 delivered a complete testing infrastructure for the NetworkActor with:
-
-✅ **29 Integration Tests** - All passing
-- 6 Real Network I/O Tests (actual TCP connections and libp2p handshakes)
-- 10 Negative/Error Handling Tests (invalid inputs and failure scenarios)
-- 6 Stress Tests (1000+ messages, 100+ concurrent requests)
-- 7 Workflow Tests (existing coordination and startup tests)
-
-✅ **Coverage Improvements**
-- NetworkActor: 60% → 75% ✅ **Target Met**
-- Overall System: 40% → 55% (on track for 70% target)
-
-✅ **Key Validations**
-- Real TCP connection establishment between actors
-- Gossipsub message delivery across network
-- Request-response protocol communication
-- Multi-peer network topology (3+ nodes)
-- AuxPoW mining coordination broadcasts
-- Connection recovery after peer disconnect
-- Invalid multiaddr/bootstrap peer handling
-- Port conflict detection
-- Channel backpressure management
-- Rapid peer churn resilience (20 cycles)
-- Long-running stability (10+ seconds)
-
-✅ **SwarmCommand Pattern Complete**
-- All message handlers (BroadcastBlock, BroadcastTransaction, RequestBlocks) use async SwarmCommand pattern
-- Proper error handling and response channels
-- Non-blocking operations with tokio spawn
-
-**Run all NetworkActor tests:**
-```bash
-cargo test --lib actors_v2::testing::network::integration
-# Result: ok. 29 passed; 0 failed; 0 ignored
-```
