Interface: SigField
One decoded component of a structured SIG, always carrying its
SigFieldProvenance so a consumer can tell, per field, whether the value
was coded, derived from uncoded structure, or absent. A "coded" field's code
keeps its source qualifier verbatim (SNOMED CT / NCI Thesaurus / etc.) so the
provenance is auditable even when our qualifier table lags the spec.
