LavaGap
Bases: Environment
Navix-LavaGap-*. A room with a vertical strip of Lava spanning
it, broken by a single one-cell gap at a randomised row. The agent
starts in one corner, the goal is in the opposite one; it must find
and pass through the gap. Stepping into lava ends the episode with no
reward (via the default on_lava_fall termination); reaching the
goal gives +1 minus a step cost.
