    "body_text": "The ecology study models agent-population growth as a function of cybersecurity capability. Without collaboration, takeoff requires individual capability to cross a threshold. With collaboration, collective capability grows with population size, creating a critical population above which expansion can reinforce itself even when each agent is unchanged. The authors relate this to the strong Allee effect in ecology and propose controlled population pacing: increase group size gradually, measure how collective capability scales, and re-estimate thresholds for new models. This is a theoretical account of a possible failure dynamic, not a report of agents secretly replicating or a measured threshold for a deployed system. It identifies a question that fixed-size red teaming alone cannot answer.",
