Absolute URL the patient opens to submit answers via the web channel (ADR 0011). Set by the orchestrator (handleTaskDue) on outbound CRs at dispatch time — unconditionally for RCS-medium questionnaire CRs (ADR 0012: the RCS sidecar renders this as an in-messenger webview button and never plays the questionnaire in-band), and conditionally for WhatsApp/web CRs (locale-gated). Read by each consumer channel to embed the link: WhatsApp embeds it in the invitation template payload; RCS renders it as an OpenUrl webview suggestion (openUrlProperties.application=WEBVIEW). The web-functions app renders the questionnaire at this URL.
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.
