description	Bridge deterministic web code and generative LLMs via hybrid world models. State and physics defined by TypeScript code, LLMs generate narrative/aesthetics on top. Uses typed interfaces, deterministic hashing, graceful degradation—enabling scalable interactive environments from travel atlases to fictional worlds without databases.

Overview

Web World Models combine structured code for invariant state with LLM-driven narrative generation.

Core Technique

Two-Layer Architecture:

# Physics layer (deterministic code)
class Physics:
    inventories: dict  # Code enforces consistency
    coordinates: XYZ

# Imagination layer (LLM-driven)
class Narrative:
    descriptions = llm.generate(physics_state)
    dialogue = llm.generate(context)
