Phase-2 dataset. 6 agents (harness×model) each played su15, continuously crystallizing a structured world model (Agent-Native Research Artifact). Here each agent's ARA is sliced at fixed absolute cumulative inference-cost budgets — $13/$27/$51/$76 — so you can ask "for a spend of $B, what world model has each agent built?"
