the crossing · the deer spawns right and must reach the left edge · walk, trot, gallop, sprint and bound are distinct states with distinct costs · a wolf trots for ten hours and sprints for nine seconds · a touch is a catch
Derived in specs/pack-hunt-energy.md from grey wolf and white-tailed deer field figures. Cost is energy per second; a full tank is 1.0. Walk and trot are negative — both animals travel for free, which is the whole asymmetry: the wolf refills in 217 s and the deer needs 789.

Set both sides, then run a hunt to watch the crossing. Wolf cooperation is the interesting dial — a high-cooperation pack visibly fences the field; a risky deer threads the needle, and a deer that spends its tank early finishes the crossing at a stumble.
