Rb 5S→6S two-photon spectroscopy at 993 nm in a hot vapour cell, OIST 2025. A line model sampled atom by atom through the bore-clipped forward beam, a digital twin that measures the estimators' biases, and work toward one joint fit of the traces and the line's higher moments. Every invariance is enumerated, never assumed.
