A confident answer is not enough.
The more consequential the decision, the less useful an unsupported conclusion becomes. A buyer, operator, resident, analyst, or reviewer needs to know where a claim came from, how current it is, and what changed between source and presentation.
Provenance makes that inspection possible without forcing every user to reconstruct the entire analysis.
Preserve the chain, not only the citation.
Good source discipline includes the original record, retrieval or effective date, transformations, entity resolution, review state, and any limitation that changes how the evidence should be interpreted.
The interface can progressively disclose that depth: a clear source label first, an evidence view next, and technical lineage when scrutiny requires it.
Trust is designed in small interactions.
Source links, freshness labels, correction paths, explicit uncertainty, and distinctions between record and interpretation all tell the user that the system expects to be checked.
That posture does more than reduce risk. It makes the intelligence more usable because people can move from conclusion to verification without leaving the decision context behind.
