"Operation Capture"

I would like to know about the save files. Do they need to be submitted in a very strict format (at the beginning and end of the day)?
And also, will everyone need to write descriptions? And is it even necessary to write them?

As a rule, only the winner writes the description, as well as the player whose playthrough, judging by the final result, raises doubts... But this map is not large, and any player can create a schematic description in a few minutes...
