Research direction
No file or test entry point is named. Start by reviewing the repository's existing decimal-column and encoding samples, then determine how fixtures represent FIXED_LEN_BYTE_ARRAY with DELTA_BYTE_ARRAY across different precisions. Done means a reproducible sample covering the requested decimal precisions is added and can be consumed by the affected readers.
