Managing State Beyond ViewModels and Hilt
summary
Migrates from Hilt to Anvil and replaces Android-controlled ViewModel lifecycles with an app-managed scope system that ties Dagger components and coroutine scopes to named scopes (root, user, locked-out) using Dagger multi‑bindings; implements a tiny scoped interface with onEnter/onExit and register/getService APIs to create and tear down services without leaking init details; builds a unidirectional presenter→model→renderer pipeline using CashApp’s molecule runtime and template renderers so business logic runs independent of activities and is easy to unit test with turbine.
