Interface: RetainedQuasiIdentifier

One entry in the retained-quasi-identifier residual inventory - a coarse identifying element the pass deliberately kept for analytic utility and recorded as DEID_RESIDUAL_RETAINED: a year-only date, a retained safe 3-digit ZIP prefix, an exact age ≤ 89. These are exactly the residuals an expert reasons about under the §164.514(b)(2)(ii) actual-knowledge test.

Example​

import { buildExpertDeterminationSupportReport, SAFE_HARBOR_CATEGORIES } from "@cosyte/deid";

const report = buildExpertDeterminationSupportReport([
  { category: SAFE_HARBOR_CATEGORIES.DATES, transform: "generalize", locus: "PID-7", count: 1,
    disposition: "transformed", code: "DEID_RESIDUAL_RETAINED" },
]);
report.retainedQuasiIdentifiers[0]?.locus; // => "PID-7"
