Resource Profile: Projo Task ( Experimental )

A single questionnaire dispatch. Tasks are materialized server-side by Fire Arrow from CarePlan (via PlanDefinition/$apply), then claimed and driven to completion by the orchestrator's handleTaskDue handler. The Task is the central anchor: it links to the CarePlan it came from (basedOn), the CommunicationRequest it dispatched (output), and the QuestionnaireResponse it ultimately collected (output). HAPI does not auto-index CommunicationRequest.about (HAPI-0524), so the CR↔Task link lives on Task.output rather than ?about= searches. Carries the delivery-time extension (the only active Task extension Projo writes today).

Documentation-only artifact. Projo's runtime extensions, code systems, identifier systems and search parameter are TypeScript constants and bootstrap-time resources, NOT deployed StructureDefinitions. This StructureDefinition exists to document the contract; the source of truth is src/functions/src/lib/fhir/types.ts and docs/FHIR_EXTENSIONS.md.
