Abstract
Raman scattering experiments on ${\mathrm{Na}}_{x}{\mathrm{CoO}}_{2}\ifmmode\cdot\else\textperiodcentered\fi{}y{\mathrm{H}}_{2}\mathrm{O}$ single crystals show a broad electronic continuum with a pronounced peak around $100\text{ }\text{ }{\mathrm{cm}}^{\ensuremath{-}1}$ and a cutoff at approximately $560\text{ }\text{ }{\mathrm{cm}}^{\ensuremath{-}1}$ over a wide range of doping levels. The electronic Raman spectra in superconducting and nonsuperconducting samples are similar at room temperature, but evolve in markedly different ways with decreasing temperature. For superconducting samples, the low-energy spectral weight is depleted upon cooling below ${T}^{*}\ensuremath{\sim}150\text{ }\text{ }\mathrm{K}$, indicating the opening of a pseudogap that is not present in nonsuperconducting materials. Weak additional phonon modes observed below ${T}^{*}$ suggest that the pseudogap is associated with charge ordering.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
