Deterministic conditions
Steam Market Database describes unusual observed conditions. It does not predict prices or tell users what to buy and sell.
All values are demonstration data; coverage and freshness language are part of the prototype trust model.

Every card identifies its entity, observation window, baseline, metric, confidence, and supporting evidence.

Interpretation boundary
Production events should be created from versioned thresholds and stored metrics. If the evidence is incomplete, stale, or unsupported, the interface should suppress the conclusion rather than substitute certainty.
