Abstract
The polar Kerr effect, or equivalently the ac anomalous Hall effect, is a signature of time-reversal symmetry breaking in chiral superconductors. Seeing it requires additional ingredients, such as disorder or multiple bands. The simplest model of chiral superconductivity in UPt${}_{3}$, which is thought to be $f$ wave, would not exhibit a Kerr effect. Here, it is shown that the ``starfish'' Fermi surface, where the bands stick together at the top and bottom of the Brillouin zone, can exhibit a Kerr effect due to multiband effects and to mixing of $f$- and $d$-wave order parameters that are respectively even and odd in the hcp sublattice index.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
