Solar Flares as a Test of the Metric Theory_ Differential Response of Atomic Clocks with Varying Sensitivity to the Fine-Structure Constant

This preprint proposes a direct test of the Metric Theory using solar flares and atomic clocks. The theory predicts that solar flares generate local fluctuations in the fine-structure constant α, which should produce a differential shift between atomic clock transitions with different sensitivities (K_α). We identify Yb⁺ E2, Yb⁺ E3, and Al⁺ as an optimal three-channel detector, provide a detailed data analysis protocol, a list of controlled systematics, and a graded falsification criterion. The test is independent of LENR experiments and probes the existence of metric perturbations directly. A positive result would link LENR, astrophysics, and precision metrology. This is the second document in a three-part verification program.
