@tao @11011110 @enzuber Do you agree that the participant's proof here is correct? https://codeberg.org/boud/MathsOlympiad/src/branch/main/Olimpiada_Matematyczna_Zadanie_6.pdf

The Polish Maths Olympiad committee gave this proof a grade of 0. The possible grades range from 0 (completely wrong) to 6 (completely correct). To me the solution is correct and elegant and the grade should be revised to 6.

An appeal to the committee will be lodged, but having independent opinions might help.
