### What changed Dictionary concatenation now converts the element position to a byte offset before zeroing null index runs in concatDictIndices. ### Why concatDictIndices tracks pos in elements, but the null-run branch used it as a byte offset. For dictionary index widths larger than one byte, that could zero the wrong byte range, corrupting adjacent valid indices while leaving the null slot's bytes stale. ### Validation - go test ./arrow/array -run TestConcatDictionaryNullIndexRunsPreserveWideIndices -count=1 - go test ./arrow/array -count=1 - PARQUET_TEST_DATA=/Users/hoangvu/Code/OSS/arrow-go/parquet-testing/data ARROW_TEST_DATA=/Users/hoangvu/Code/OSS/arrow-go/arrow-testing/data go test ./... -count=1 -- This is an automated message from the Apache Git Service.
