Proximity = influence closeness. Ring 1 actors have daily, direct contact with youth behaviour. Ring 2 actors shape the structural context in which choices happen. Ring 3 actors define the systemic options available.
Border style = evidence confidence. Solid borders mean we have strong primary data from the IDIs — enough to inform direction with confidence. Dashed borders mean influence was referenced but not directly studied. Dotted borders mark actors we know matter but haven't explored — each includes a recommended Phase 2 workstream.
The strategic implication: Our current research has depth along the parent-youth-peer axis. Everything beyond that ring carries evidence gaps that need further structured inquiry before we can act on them. The under-explored actors aren't unknowns — they're named research investments.
