Limits and evidence boundaries

Results describe observed public evidence and its provenance.

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.

Asynchronous jobs return an identifier for status polling and later result retrieval.

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.
