How vin0414/d-prwrf works
CodeIgniter 4 is a PHP full-stack web framework. Its principal runtime workflow accepts an HTTP request, constructs request state, matches configured routes, invokes a controller, and emits an HTTP response. The repository also provides database/model access, validation, sessions, filters, views, caching, REST support, and CLI commands. The graph follows documented and indexed relationships; unsampled subsystems are included as capabilities, but their internal call links are omitted where evidence is unavailable.
