Resolve a NAICS 2022 code to its industry title: Complete for the bundled 2022 vintage: all 2129 NAICS 2022 codes at levels 2 through 6, titles verbatim from the Census workbook, with the three range-spelled sectors (31-33, 44-45, 48-49) expanded to one entry per member sector. NAICS is a closed set, so a well-formed code absent from this snapshot is absent from the 2022 vintage. Refresh is a redeploy, never a live fetch.
