Android Architecture Standards

Priority: P0 (CRITICAL)

1. Layer Your Project (Clean Architecture)

• Domain: Pure Kotlin (No Android deps). Contains UseCases and Models.
• Data: Repository impl, DataSources (API/DB). Maps DTO -> Domain.
• UI: ViewModel + Composable. Maps Domain -> UiState.

See structure & examples for Clean Architecture layer examples.

2. Modularize by Feature and Core

• Feature Modules: :feature:home, :feature:profile.
• Core Modules: :core:ui (Design System), :core:network, :core:database.
• App Module: DI Root and Navigation Guard.

See structure & examples for module configuration.
