legacy_2017 ONLY (NULL in current_2025, and NULL for any legacy_2017 row too since no exception was ever observed). Byte offset [62:67) of the old cab layout — observed as the literal constant '0.000' across all 279137 real sample rows (6 different years, 2017-2025), ingested anyway in case a future row breaks the constant.
