Task Profile

Base	Task (constraint)
Source	FSH · JSON

A unit of work in the chart: who asked for it, who owns it now, what has been said about it, and which chart element it concerns. Inbox items, to-dos, follow-ups, a result that needs review -- deliberately one kind of work item.

TypedFhir API / TypeScript

The typed accessor surface Task exposes for Task — generated from this IG's compiled profile; each typed accessor has a validating raw-FHIR twin (xRaw) where marked. The three ports are parity-enforced.
