Preview surface — demo data. Where real data exists today (e.g. RealT, BlackRock BUIDL, Lift Dollar) we render it; everywhere else we render synthetic enrichment generated deterministically from public signal and clearly marked Demo or Inferred. The Phase 3 roadmap replaces every synthetic source with live ingestion — see Methodology → Exposure Graph & Similarity Engine.
