Let $C$ be a simplicial complex on a fixed vertex set $V$ with $|V|=4$.

We are modeling a situation where a person repeatedly produces probabilistic “fireworks batches” over time. Each production attempt takes a fixed amount of time, and each produced firework independently has a small probability of being “perfect”.

We are building a walk on an infinite grid starting from the origin. Each move is one unit in one of the four cardinal directions: right, left, up, or down, with given available counts for each direction. The final walk must use exactly all moves.
