Covers turning users into contributors and contributors into regulars: curating genuinely good first issues, onboarding paths and checklists generated from the repository, first-PR shepherding, mentorship and buddy structures, and measuring where the contribution funnel leaks. Use when a project wants contributors but gets none, when first-time contributors do not return, when the user asks for good-first-issue curation, onboarding documentation or mentorship structure, or when a team member or student is joining a research software project.
