Variable: LIMITED_DATA_SET_PROFILE

const LIMITED_DATA_SET_PROFILE: DeidProfile

The Limited Data Set / longitudinal research profile. Identical to Safe Harbor except dates are date-shifted (a single consistent per-patient offset, intervals preserved) rather than generalized to year - so time-series analysis survives.

This is deliberately less protective than Safe Harbor and is NOT Safe Harbor. A shifted-but-real date is still "an element of a date" (§164.514(b)(2)(i)(C)), so this profile:

• is not labelled safe-harbor (the reserved-label guard would reject it);
• requires a keyed per-patient DeidContext (an absent key is a fatal DEID_NO_KEY);
• produces an Expert-Determination-supporting dataset, not a certified de-identification, and not, on its own, a HIPAA §164.514(e) Limited Data Set - disclosing an actual Limited Data Set additionally requires a Data Use Agreement, which is the consumer's responsibility.

Example

import { LIMITED_DATA_SET_PROFILE } from "@cosyte/deid";

LIMITED_DATA_SET_PROFILE.requiresContext; // => true (date-shift needs a per-patient key)
