@cosyte/deid

Public entry point for @cosyte/deid - a healthcare de-identification engine.

@cosyte/deid is not a parser. It is a consumer-tier library: it applies a HIPAA-grounded de-identification policy (Safe Harbor by default) to a structurally-located model of a healthcare document and returns a transformed model plus a value-free manifest of what it acted on. It borrows the parser archetype's disciplines (typed diagnostics, immutable output, a policy/profile system) but inverts the parser's reflex: it fails closed - an unrecognized structure or an un-locatable identifier is blocked, never passed through as safe.

Honesty line (governs the whole library). Results are "Safe-Harbor-transformed per the configured policy" - never "de-identified" and never "HIPAA-compliant". Safe Harbor is implemented mechanically; the §164.514(b)(2)(ii) actual-knowledge condition is the consumer's; Expert Determination (§164.514(b)(1)) is supported, never rendered or certified here.

The root entry ships the format-agnostic core: the policy engine, the five transforms, the 18-category Safe Harbor model, the fail-closed rule, and the value-free manifest - tested against a generic locus model. The per-format locus maps (HL7 v2, C-CDA, FHIR, X12, NCPDP, DICOM) live behind the matching subpath exports.
