How the scores are decided
Deterministic rules compute every score. Company verdicts: dissolved, in administration, accounts overdue, officer churn, a financial-services SIC code with no FCA match, and so on. Tender fit-scores: five published factors (relevance, value fit, geography, timeline, buyer history), each returned with its numerator and denominator so you can re-weight client-side. Each rule that fires is named in the response so you can audit or override it. A language model writes the short narrative fields and nothing else; if it is unavailable they are null and every other field still ships.
Tender data honesty: when a source notice carries no CPV codes, you get cpv: null — never a guess — and the official notice link travels in every response so you can verify against source.
