 ## Where paracosm sits in the world-model landscape
 
-Paracosm is a structured world model in the sense of [Xing 2025](https://arxiv.org/abs/2507.05169) and the [ACM CSUR 2025 world-model survey](https://dl.acm.org/doi/full/10.1145/3746449), and a counterfactual world simulation model in the sense of [Kirfel et al, Stanford 2025](https://cicl.stanford.edu/papers/kirfel2025when.pdf). It is **not** a generative visual or spatial world model (Sora, Genie 3, World Labs Marble), **not** a JEPA-style predictive-representation model (LeCun's AMI Labs), **not** a multi-agent task orchestration framework (LangGraph, AutoGen, CrewAI, OpenAI Agents SDK), **not** a bottom-up swarm intelligence simulator (MiroFish, OASIS), and **not** a generative-agents library (Stanford Generative Agents, Google DeepMind Concordia). It is a JSON-defined state space + deterministic seeded kernel + LLM-driven events and specialist analyses + HEXACO-personality leaders + universal Zod-validated run artifact spanning turn-loop civilization simulations, batch-trajectory digital twins, and batch-point forecasts.
