If you don't have further arguments and especially any answer to my question "How do you land safe in the event of failure of the critical engine (OEI) within the rejected take-off distance, if you have performed rejected or vertical takeoff eg. from a tanker having speed ahead or if you are performing HHO or HEC, e.g. marine pilot transfer or SAR missions, without OEI HOGE?"
You don't - you go somewhere else where you can land.
...or safely continue the flight to an appropriate landing area
