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.
