Repository Onboarding Simulator

 Build an interactive onboarding simulator for developers joining an unfamiliar codebase. Analyze the repository structure, dependencies, configuration, major modules, routes, database models, APIs, tests, and documentation. Generate a progressive learning journey where developers investigate the codebase through realistic missions such as “trace this request,” “find where this value is stored,” or “explain how authentication works.” Provide hints without immediately revealing answers and track which parts of the architecture the developer understands.
