HIGH PRIORITY FIXES: - Extract shared buffer parsing logic into parseProtobufFrames generator method (DRY violation fix) - both JSON and SSE transformers now use common frame parsing loop, eliminating ~60% code duplication - Use COMPRESS_FLAG constants instead of hardcoded 0x01/0x02/0x03 in parseConnectRPCFrame for better maintainability MEDIUM PRIORITY FIXES: - Return empty buffer on gzip decompression failure (prevents silent data corruption) - ALREADY FIXED - Add debug warning for unknown message roles in convertMessages - Create GitHub issue #535 for FIELD namespace refactoring follow-up - Add test coverage: transformProtobufToSSE, error paths, unknown roles LOW PRIORITY FIXES: - Rename checksum test to clarify timestamp granularity (~16 min) - Fix debug log function name in SSE transformer - FIXED BY REFACTOR - Add comment to TOOL_RESULT_RESULT field documenting future use All tests pass (1593 pass, 0 fail) All validation checks pass (typecheck + lint + format + tests)
