Lexicon
Concept entries
A compact orientation for each concept: a preferred label, a definition, a scope note that names the distinction to preserve, justified synonyms, and links to related entries and the monograph that develops the idea.
These fifty entries are an editorial seed, not a terminology release. Their NX-C identifiers are local to this publication and imply no SNOMED CT® concept, no external code, and no mapping. External mappings are deliberately left empty until they can be recorded with source, version, relation, evidence, and a reviewer.
