 ## Continuous Integration
 
 - **.github/workflows/CakeFile.yml**: Runs the file-based build script on push/PR.
 - **.github/workflows/CakeProj.yml**: Runs the project-based build script on push/PR.
+- **.github/workflows/Cake_Sdk-MultiFile.yml**: Runs the multi-file-based build script on push/PR.
 
 Both workflows use the pinned .NET SDK and Cake.Sdk versions from `global.json`.
