# Why Patient-Friendly Documents Should Not Require Losing Clinical Provenance

Plain-language presentation can remain grounded in the same source document, with citations and refusal when the answer is not contained there.

## Bounded UD model

UDR records change. UDS preserves an exact sealed state. BrowserCarrier provides offline-readable delivery. Local document intelligence answers only from contained text and cites its source.

## Claims boundary

Technical provenance does not establish clinical truth, HIPAA compliance, identity assurance, medical necessity, patient-safety outcomes or regulatory approval.
