Rosie: use case framework

on YouTube ↗35m

" summary

Karumi ships Rosie after 1.5 years of iteration as a concrete app framework focused on testability, scalability and readability, with internal code on GitHub and real reuse across many short‑deadline projects. Implementation details: presenter/passive-view UI, explicit domain use-case task scheduler (synchronous test runner plus threaded implementations), dynamic proxies to avoid nulls, and a repository pattern with memory cache and persister that populates Realm/Retrofit sources. It removes boilerplate, avoids heavy retained instances to prevent leaks, and proves workable in production apps.
