  "_comment": "Manufacturer alias map, seeded from the SSF list content (both 05/15 and 07/01). Keys are canonical UPPERCASE manufacturer names; values are the variant spellings/abbreviations that resolve to them. Used two ways: (1) normalize.py folds every variant to its canonical manufacturer_norm so alternate spellings group and produce one stable id; (2) the lookup island expands a user's manufacturer term across the whole cluster. Grown manually via correction reports. Deliberately NOT merged (real, distinct makers with similar names): RADICAL FIREARMS vs RADIKAL FIREARMS, TARAN TACTICAL vs TITAN TACTICAL, ADAMS ARMS vs DS ARMS.",
