Goal-Driven Autonomous Optical Experimentation via a Self-Recursive Hardware-Software Harness

Spectral feedback reduces one target color difference from 19.756 to 1.211 {\Delta}E_76^*; all five targets improve in a separate comparison. It comes from a paper posted to arXiv on 4 November 2026. We propose goal-driven self-recursive optical research in which agents use physical evidence to revise the hardware, software, models, and protocols used to pursue a scientific goal. The framework can be instantiated with different stimulus systems and measurement devices. We formalize its updates and derive a relation between physical attainability, command access, and model approximation error. We demonstrate the concept in an optical see-through color-matching case study using an iPad, RayNeo X3 glasses, and a TOP 300 probe coupled to a CAS140D spectroradiometer, both from Instrument Systems. A revised glasses application adds USB-controlled RGB holds and frame acknowledgements, keeping model-generated colors displayed during spectral acquisition. The interface passes 12 live control checks. These measurements demonstrate the concept in one configuration. The resulting software and protocols remain available for subsequent investigations.
