• Add a unit or integration test to verify that the PIA tool correctly recognizes and processes AssemblyKeyFileAttribute and AssemblySignatureKeyAttribute.

            { "System.Reflection.AssemblyKeyFileAttribute", System_Runtime },

src/tools/MakePIAPortableTool/MakePIAPortableTool.cs:44

• Confirm that AssemblySignatureKeyAttribute is a valid attribute in the targeted runtime; if the actual attribute is named differently (e.g., AssemblyKeyNameAttribute), update this mapping accordingly.

            { "System.Reflection.AssemblySignatureKeyAttribute", System_Runtime },
