Auditable Clinical Timeline Reconstruction with Provenance-Aware Evidence Graphs

arXiv:2610.06177v1 Announce Type: new Abstract: A patient-timeline reconstruction system is auditable only if it keeps the mentions behind each answer, records how facts were revised, and declines to answer when the evidence is not in the text. This study tests these three properties on a fully synthetic corpus (1,000 patients, 3,353 notes, 220 revision edges). Two provenance-aware Evidence Graph operators reduced the node-plus-edge count to 67% and 63% (77-78% of serialized size) while preservi
