+// then one day, when the User model changes, the existing migration will break because it will use the new (incorrect) User model,
+// it should only use the old User model.

+// Related: "models", "modules/structs", git repo directory layout on the disk, etc.

+// If changes happen, the old migrations need to use a snapshot struct/function (copy the code and freeze)
