i think their territorial loss will be at the least all the way to hasakah, they may get to keep a bit of land to the furthest north-east deir ez zor cut off, next should be al tabqah, anything further north than that can be picked off by turkish drones, after al tabqah, raqqa is basically cut off from deir ez zor and al tabqah, no reinforcements, no logistical supply lines
