Why is it considered a normal source file and a KSP generated source file to be in "different module"?
I have a sealed interface A in module-folder/src/jvmMain/kotlin and I generate another interface interface B: A with KSP in module-folder/build/generated/ksp/jvm/jvmMain/kotlin (A and B are in the same package).
The error message is: Inheritance of sealed classes or interfaces from different module is prohibited

They should be compiled together and considered living within the same module. Can you share more details?

It was my mistake: the interface A was in module-folder/src/commonMain/kotlin (not in jvmMain as I wrote above).
If I move it to module-folder/src/jvmMain/kotlin it works as expected.
Sorry for the confusion.
