Key points
- Construction fidelity is a model-level property that measures whether a VLM's intended construction matches the requirements of the problem.
- Explicit reading channel: observations showed that 74 to 91 percent of the system's derived answers included at least one value explicitly returned by the engine, confirming that the VLM actively uses the engine as a source of truth rather than relying only on its internal prior knowledge.
- Correction and replanning capability: after receiving an error message and using the object deletion tool, the model can correct its path. When a construction path leads to a contradiction or an invalid state, the model can backtrack and try an alternative strategy, just like a human mathematician using compass and straightedge.
