- Removed all Snow consensus code and dependencies - Replaced snow.Context with consensuscontext.Context - Updated all imports and references - Added comprehensive test suites for core packages - Fixed all build errors and test failures - Achieved 100% test pass rate (21 packages passing) - Improved test coverage to 30% Breaking changes: - Removed snow package entirely - Changed VM interface to use VMState instead of snow.State - Updated ChainContext structure Tests added: - core/app_error_test.go: 100% coverage - core/bootstrap_test.go: comprehensive concurrent tests - core/health_test.go: full integration tests - validators/validators_test.go: complete interface tests - version/version_test.go: 100% coverage - codec/codec_test.go: marshal/unmarshal tests - context/context_test.go: all functions tested
