Limits and evidence boundaries

Confidence describes evidence strength for the reported observation, not certainty about the real-world entity.

Coverage is bounded by the documented inputs, budgets, sources, and response limits.

Bulk operations process multiple supported inputs while preserving documented item-level outcomes.

Partial means some requested items or components completed while others did not.

Cached indicates that stored evidence was used; review freshness metadata where provided.

The product evaluates public inputs and publicly observable evidence only.
