}Limits and evidence boundaries
Results describe observed public evidence and its provenance.
Unknown means the requested fact could not be determined from the available evidence.
Bulk operations process multiple supported inputs while preserving documented item-level outcomes.
Coverage is bounded by the documented inputs, budgets, sources, and response limits.
Evidence can change over time; use timestamps and freshness fields when provided.
