Fit-to-haul verdict for a US motor carrier from FMCSA registration data. Give one of dot, mc or name and get a verdict (fit, caution, unfit or not_found), a 0-100 fit score, per-dimension flags, reasons and weighted signals across authority status, operation, hazmat, safety rating, history, registration freshness, address and fleet. Deterministic, no LLM. Carrier vetting indicators, not legal or compliance advice.
