wildlife_set_crowd(a, true) hands a walker to a crowd. Its step no longer moves it, and its want is two fields on it: goal_x / goal_z (the point it heads for or faces) and goal_speed (0 when it stands). A route reads those and hands back where the crowd put it through wildlife_moved(a, x, z, vx, vz). That sets its place, its ground, its heading from its velocity and its prints, and updates its row's columns so the spatial index finds it there. Nothing allocates per animal per frame: the want is the animal's own fields, and moved writes in place. The prints and the turn counters moved to walked.ludic (steer.ludic was at the 100-line limit). crowd_test holds it; with crowd off every old test is unchanged. wildlife 26/26.

Written while builds are held (agents share 16 GB; no build or run until the user lifts it), so
it has not been compiled or tested. The animals are rows of a ludic.base Table: x, z, species and
alive as columns, a 32 m grid over the living, the living by species, and a nid map.
wildlife_by_nid is a map lookup instead of a scan of every animal ever made, wildlife_count walks
only its species, wildlife_nearest asks the grid, wildlife_set_alive writes the flag and the row
together, and wildlife_refile files the tick's moves once after it (wildlife_verify holds the
columns to the records). A guest puts its whole table away and brings it back. A test case covers
them; to run once builds are allowed: ludic test packages/ludic.wildlife.
