The clockwork wades, shelters, and honors pacts it can actually break

Game 6XDY's prisoners expose a nest of turn-burners. The pathfinder
treated pits, ooze, bushes, and slime as walls in transit, so bots stood
"trapped" in pockets any human would wade out of: the march now falls
back to a teeth-gritted hazard route when no clean road exists. Bots no
longer aim attacks into (or out of) a thornbush's shelter the engine
refuses; WIZARDBLADE learns it is a blade (same square only); a cursed
IDIOT skips every rung the curse would refuse instead of burning turns
on them; BUDDY's orientation is righted — whoever pacted YOU is
untouchable, your own pacts are merely precious — and a thief standing
underfoot no longer becomes a null destination that freezes two laden
wizards on the same square forever.
