By your interpretation of the Fourth Article, essentially everything the states do is subject to Congressional approval or action because everything the states do has an effect, however large or small. This flies in the face of the Tenth Amendment.

I never said they have to get approval. I said they have to allow the Congress to prescribe the way any state proves their acts.

This flies in the face of the Tenth Amendment.

The tenth amendment doesn't apply to secession because Article IV says that the Congress may prescribe laws for states to prove their acts. The tenth amendment says power not delegated to the United States. Article IV delegates to the Congress the power to prescribe laws for states to prove their acts.
