Typically we'd wrap all properties before Vue instruments a model. However, if the model gets passed into a call while the constructor is still running, and the call happens to add it to previously- instrumented object, then Vue will instrument the model early. We must then be very careful not to overwrite Vue's accessors with our own wrappers or the property will stop being reactive!

Typically we'd add and wrap all properties before Vue instruments a model. However, if the model gets passed into a call while the constructor is still running, and the call happens to add it to previously- instrumented object, then Vue will instrument the model early. We must then be very careful not to overwrite Vue's accessors with our own wrappers or the property will stop being reactive. We must also make sure that any properties added afterwards (such as computed ones) get instrumented by Vue and trigger any watchers already installed on the model.
I'm honestly not sure I would've figured this out without Codex.
