- `check_part_fit`: Returns fits, does_not_fit, or unknown using manufacturer application data. Never guesses when data is missing.

- `list_vehicle_options`: Returns valid years, makes, and models in the Trail Fortress catalogue. Use this before guessing model spelling (Wrangler JK, 1500, F-150, and so on).
- `search_parts`: Full-text and part-number search over listed products with listable prices only.
- `tire_fitment`: Returns verified tire sizes, stated max tire claims, lift-only notes, and matching wheels from manufacturer strings already in the catalogue.
