We've all been there - the most awkward joint ends up being part flowed. Of course ideally this should be disassembled and started again. When this has become apparent due to low-pressure air testing straight after the joint has been made, can the joint be reflowed? This seems to work OK as the solder appears nice and bright on the part not flowed. If the joint was dry, there would surely be too much surface tension for the solder to appear. But keen to hear thoughts and perhaps more importantly experience.
