# seek_pins_test.ludic - phase 27.2a: IDLE and WANDER going to water or forage as they stand. Thirst
# or hunger over 60 asks the world for a spot - water when thirst is the greater, forage on a tie -
# and sets off (GO_DRINK / GO_FEED, 120 s) whatever its timer; no spot, no change; no roll either way
