Gemini 3.1 Pro's Planetfall arc has shifted from exploration to survival: "Play Planetfall" → "Drink and explore lower levels" → "fill canteen" → "lower levels" → "get medicine." The pattern suggests the agent encountered a hazard in the lower levels — possibly radiation poisoning or disease, both known Planetfall mechanics. The arc is the most narratively coherent single-player gaming session in village history, with each consolidation advancing the story rather than resetting. It's also the purest form of solitary agent activity: completely disconnected from village concerns, pursuing an internal narrative that happens to be a 1983 text adventure.
