Plain-Language Brief

The paper introduces ChemWorld, a programmable chemical environment that allows researchers to create executable worlds with reusable components. This environment separates the experimental contract available to an agent from the evaluator-owned chemical laws, enabling variation in world composition and operating conditions while maintaining a fixed public task and interaction conditions. The paper claims that ChemWorld ensures exact replay and auditing of environment-action trajectories, and demonstrates its functionality through various deterministic experimental cases.

What the Document Says

• ChemWorld is a programmable chemical environment with reusable components.
• It separates the public experimental contract from evaluator-owned chemical laws.
• Researchers can vary world composition and operating conditions while holding the public task and interaction conditions fixed.
• Transactional execution records operations, failures, resource changes, and state transitions for exact replay and auditing.
• Full-census qualification covers reference registry, 52 generated compositions, module, interface, compilation, and invalid-action tests.
• Eight deterministic experimental cases demonstrate shared lifecycle semantics, failure recovery, and exact replay.
• Six parent-child world-fork pairs isolate the effects of single private-law interventions under matched public conditions.
• An independent agent completes a full lifecycle in a non-reference world through the same public interface.
• ChemWorld provides a controlled and replayable substrate for studying experimentation across systematically varied chemical worlds.

Raw Abstract / Excerpt

Autonomous chemistry increasingly depends on environments in which agents can repeatedly act, observe, and adapt.Physical laboratories provide essential real-material evidence but are costly to repeat and difficult to use for tightly matched interventions, whereas most digital environments keep the underlying experimental world largely fixed. We introduce ChemWorld, a programmable chemical environment in which reusable process and observation components are compiled into executable worlds. ChemWorld separates the public experimental contract available to an agent from evaluator-owned chemical and material laws. Researchers can therefore vary world composition and operating conditions, or change a single hidden law while holding the public task and interaction conditions fixed. Transactional execution records operations, failures, resource changes, and state transitions, allowing complete environment-action trajectories to be replayed exactly and audited. Full-census qualification covered the reference registry, 52 generated compositions, and module, interface, compilation, and invalid-action tests. Eight deterministic experimental cases demonstrated shared lifecycle semantics, failure recovery, and exact replay, while six parent-child world-fork pairs isolated the effects of single private-law interventions under matched public conditions. An independent agent also completed a full lifecycle in a non-reference world through the same public interface. Within the declared component and model domain, ChemWorld provides a controlled and replayable substrate for studying experimentation across systematically varied chemical worlds, complementary to physical-laboratory evidence and calibration.
