 **Verification**: 27 flexible version tests pass; robust fallback for older clients; E2E compatibility maintained
 
-## Phase 7: Error Handling and Edge Cases (PRIORITY LOW)
+## Phase 7: Comprehensive Error Handling and Edge Cases (COMPLETED ✅)
 **Goal**: Comprehensive error handling and Kafka spec compliance
 
 ### Tasks:
-- [ ] Audit all error codes against Kafka specification
-- [ ] Add missing error codes for network/timeout scenarios
-- [ ] Implement proper connection timeout handling
-- [ ] Add comprehensive error handling tests

-## Current Status: Phase 1-6 completed, ready for Phase 7 (low priority)
+**Files modified**:
+- Added file: `weed/mq/kafka/protocol/errors.go` (centralized error codes)
+- Added test file: `weed/mq/kafka/protocol/error_handling_test.go`
+- `weed/mq/kafka/protocol/handler.go` (enhanced timeout handling)
+- Updated all protocol handlers to use centralized error codes
+
+**Verification**: 21 error handling tests pass; unified error code usage; robust timeout detection; E2E compatibility maintained
+
+## Current Status: All Phases 1-7 completed! ✅
+
+**Implementation Summary**: 
+- Complete Kafka protocol gateway with SeaweedMQ integration
+- All major APIs implemented (Produce, Fetch, CreateTopics, Consumer Groups, Metadata, etc.)
+- Multi-batch fetch support with MaxBytes compliance
+- Flexible version support for modern Kafka clients
+- Comprehensive error handling and timeout management
+- Extensive test coverage with 100+ tests across all components
+- Full E2E compatibility with Sarama and kafka-go clients
 
 ### Implementation Notes:
 - Each phase should include comprehensive tests
