Multi-Pass Source Collection
For each race, the engine executes 10–20 targeted web searches across five passes: Tier 1–3 press outlets (Autosport, Motorsport.com, The Race, BBC Sport, Sky Sports), international press (Auto Motor und Sport, Gazzetta dello Sport, L'Equipe, Marca), Reddit megathreads and week-after discussion, YouTube/social reaction metrics, and contextual championship data. Each source is tagged with credibility tier, geographic market, temporal distance from race, and structured sentiment scores.
