Session Ownership

From The Session You Cannot Take With You:

A user should be able to close an account, keep a session, and hand it to another model. The new model may disagree, ask questions, or perform worse. It should not be staring at ciphertext where the old model saw the user’s history, evidence, plans, and delegated work.

Agreed, and relevant to folks running local models. I want to be able to swap between different models as needed, but it seems like session context is being hidden by model providers who don’t make that easy.
