- Added detailed hex dump comparison between v0 and v1 responses - Identified v1 adds rack field (2 bytes) and is_internal field (1 byte) = 3 bytes total - kafka-go still fails with 'multiple Read calls return no data or error' - Our Metadata v1 format appears correct per protocol spec but incompatible with kafka-go
