Three guards moved onto the number they guard

An agent re-ran every 3.13.0 fix and found all of them holding, then found three places where the guard sat beside the field that needed it. A weekly row's trophy_battles counted only the ladder games the game reported a trophy delta for, so a player parked on an arena floor (where a loss costs nothing and reports nothing) showed fewer games than they played and a better record than they had; trophy_mode_battles now sits beside it as the count of ladder and Path of Legends games played, the docs name both, and a note says which weeks differ. The monthly pilot-score trend warned about the first population change it found and said nothing about a later one, even an arena crossing; it now lists every step under population_changes and names them all. And battles_decks called its denominator the battles in the window when duels were silently outside it; excluded now itemizes them and the numbers reconcile with battles_performance. Contract 4.1.0.
