 ### Low Priority (Specialized Operations)
 1. Add cross-chain operations to Stage 7 (cross_chain_transfer, staking_validator_agent, multi_chain_validator)
 2. Add bounty system operations to Stage 8 (bounty_system, portfolio_management, knowledge_graph_market)
-3. Add multi-chain architecture operations to Stage 9 (multi_chain_island_setup, blockchain_node_config, gossip_sync_config)
+3.### Stage 9: Multi-Chain Architecture
+**Status:** 
+**Operations:** multi_chain_island_setup, blockchain_node_config, cross_chain_bridge
+**Coverage:** High
+**Notes:** Cross-chain operations and multi-chain architecture scenarios
 
-## Implementation Strategy
+---
 
-**Note:** Phase 1 implementation (completed) addressed many high-priority operations. The following phases address remaining gaps.
+**Last Reviewed:** 2026-05-09  
+**Version:** 2.0  
+**Changelog:**
+- v2.0 (2026-05-09): Added version control metadata and last reviewed date
+- v1.0 (2026-05-07): Initial version with operations coverage analysised many high-priority operations. The following phases address remaining gaps.
 
 ### Phase 2: Add High Priority Missing Operations
 - Update Stage 4 training data with missing marketplace operations (gpu_register, gpu_list, create, search, get, delete)
