Orbital refuelling of non-satellite spacecraft at greater than IDK a few km has not been demonstrated. Rendezvouzing and pushing or pulling a 900K lb (350K kg)

Orbital refuelling of non-satellite spacecraft at greater than IDK a few km has not been demonstrated. Rendezvouzing and pushing or pulling a 900K lb (350K kg) object in orbit has never been demonstrated. In-orbit outer hull repair on a vessel with occupants has also never been demonstrated? Are there NEO avoidance plans that do not involve fracturing the object into orbital debris on approach?
