What It Validates

10 Critical Rules

1. Interface + Impl pairs for DataSource/Repository
2. Either for all fallible operations
3. setState { } for state updates (never direct assignment)
4. 4-state UI: Uninitialized/Loading/Success/Failed
5. X-components only (no Material3)
6. ImmutableList for collections
7. Callback parameters for navigation
8. Lowercase packages (no hyphens/underscores)
9. @Serializable on all models
10. Type-safe navigation routes

4 Integration Points

1. settings.gradle.kts includes module
2. composeApp/build.gradle.kts has dependency
3. initKoin.kt registers DI module
4. BaseAppNavHost.kt wires navigation
