Three data layers
A source can be catalogued without being product-available. Pyrametrics separates the source catalogue, versioned evidence records, and the published product layer. Only the last layer supports a live product claim.
Availability states
Available means a publication-gated source returned evidence. Limited means the scope, geography, or methodology is narrower than a general market claim. Unavailable means the product should show a clean empty state—not a simulated answer.
