 ## Overview
 
 Functorium v1.0.0-alpha.3 focuses on **IRepository redesign** and **EF Core performance optimization**. The repository interface has been reorganized into four clear responsibility groups--Write Single, Write Batch, Read, and Specification--while batch operations now bypass Change Tracker for significantly better throughput. A new `[GenerateSetters]` Source Generator eliminates the boilerplate required for EF Core `ExecuteUpdateAsync` adoption.
