@slc-capistrano — suggesting we close this one. Collecting IG improvement inputs is implied by the connectathon mission and the team's role; it doesn't need a standing tracker issue to exist. The actual feedback log lives in the linked Google Sheet. Happy to keep it open if you see value, but from the FHIRLab side this feels like overhead rather than a trackable deliverable.
