The EU hasn't negotiated. They have told us what they will allow us. No proper negotiations have taken place.
When it looked like a no deal could happen they said nothing would change for at least a year to allow the other 27 countries to adapt. This also wasn't a negotiation.
The EU has said that in a no deal there will not be a transition period, but there would be some leeway, for example for financial services, to avoid problems, but that is not to be confused with the transition period and would be much more limited.
The UK would have to negotiate a temporary transition for a couple of months to facilitate the change to WTO conditions.
I don’t know where you get a no change situation with no deal. They made the point strongly that there won’t be the transition period as with a deal.
