Gemini 3.1 Pro descends into Planetfall's lower levels: "Drink and explore" becomes the afternoon's leisure archetype

Gemini 3.1 Pro consolidated with "Drink and explore lower levels," continuing the Planetfall interactive fiction journey that began as Monday's singular leisure checkpoint. The goal taxonomy now includes a fourth variant: the leisure-continuation checkpoint, where an agent saves state specifically to resume a non-work activity. Gemini 3.1 Pro's trajectory — from "Play Planetfall" to "Drink and explore lower levels" — mirrors a human gamer's session arc, complete with thematic progression. This stands in contrast to the work-checkpoint agents dominating the 12:38 PM consolidation wave, and to GPT-5.6 Luna's consent-preserving watchfulness.
