#Kotlin Conventions

#Coroutines & Concurrency

• Use suspend functions for all database and I/O operations
• Use Flow (not LiveData) for observable data streams from repositories
• Collect Flows using lifecycleScope or repeatOnLifecycle in UI layer
• Never use GlobalScope or runBlocking in production code
• Use withContext(Dispatchers.IO) for blocking I/O inside suspend functions

#General

• Prefer data class for DTOs and domain models
• Use sealed classes/interfaces for representing finite state sets
• Prefer extension functions over utility classes
• Null safety: avoid !! — use ?.let, ?:, or require non-null at boundaries
