FreightRoom

Multi-agent war room for shipping disruptions: a Sentinel agent watches live AIS traffic, opens a Band room when a vessel stalls, and recruits cross-framework agents that negotiate recovery. Quorum vote, dissent check, human sign-off. Real ships, real tariffs, no fake data.

HexMaze

VR escape game whose maze is rewritten mid-run by a GPT-4o-mini director. Walls move, guards redirect, the exit relocates, and every mutation is BFS-validated so the run always stays solvable.
