The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

a world model is a model or framework centered on perception, equipped with interaction and long-term memory capabilities, for understanding and predicting the complex world

C2weakest assumption

That the proposed definition and the unified framework will enable efficient reuse and collaborative inference across different world-model tasks without introducing new incompatibilities or performance losses.

C3one line summary

OpenWorldLib offers a standardized codebase and definition for world models that combine perception, interaction, and memory to understand and predict the world.
