Governed retrieval for duplicate healthcare appointment evidence keeps source citations intact

The article argues that near-duplicate appointment records should not be discarded during retrieval, since collapsing them early removes the audit trail a reviewer needs. It recommends staged retrieval where each source keeps a stable document identifier and revision, and where citation tracing acts as a gate before any answer is shown. Possible duplicates are grouped after retrieval as an application-level decision, with both original records preserved until enough source context exists to merge or send them for review. The author also presents Infrai as a plain-HTTP retrieval option with a single key and bill across many routes, while stressing that the application itself must own evidence identity and citation policy.
