Design and operate an open-source contribution system: governance models, contributor onboarding, participation loops, recognition programs, community operations, and the discover-to-maintainer funnel with stage-aware gates from Stage 0 founder-led to Stage 4 foundation-scale, grounded in CHAOSS metrics and CNCF governance templates with GitHub as the operating surface. For measuring existing community health use developer-community-auditor; for the single first contribution use contributor-experience.
