Completed: Added comprehensive comments to all test files

Todo List

• Find all test files in the repository
• Review existing test files and their comments
• Add explanatory comments to Go test files
  • Orchestrator tests (statedb, simulator, bytecode_store, service, chain)
  • Protocol tests (types, types_v2)
  • Shard tests (server, chain, chain_v2, security)
  • Integration test
• Add explanatory comments to Python test files (4 files)
• Commit and push changes
• Provide PR creation link

Summary of Changes

Successfully added comprehensive documentation to all 16 test files in the repository:

Go Tests (12 files) - Added:

• File-level package comments explaining purpose, scope, and test coverage
• Documentation of V2 protocol features (2PC, RwSet, simulation, transaction types)
• Explanation of security fixes tested (pointer aliasing, goroutine leaks, refund underflow)
• Context about how tests fit into the broader system architecture

Python Tests (4 files) - Enhanced:

• Detailed docstrings explaining test flows and protocol features
• Context about V2.2 iterative re-execution and simulation
• Helper function documentation with ABI encoding details
• Expected results and timing considerations for 2PC

All test files now clearly explain:

• WHAT: The specific functionality being tested
• WHY: Why these tests matter to the system's correctness
• HOW: How tests relate to the V2 block-based 2PC protocol
