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

LabBuilder significantly outperforms existing state-of-the-art methods, producing laboratory environments that are not only realistic but also functionally valid and safe for complex experimental workflows.

C2weakest assumption

That the meta-dataset of annotated assets and chemical knowledge, combined with natural language to protocol translation, accurately captures the rigorous functional semantics and safety constraints needed for real scientific experiments.

C3one line summary

LabBuilder generates safe, protocol-compliant 3D laboratory layouts from natural language using a curated meta-dataset, constraint-aware synthesis, and a verification benchmark.
