Abstract
Aims. Or aim in this note is to compare a recent explanation of the galactic X pattern in Faraday rotation to the pattern produced by the advection part of the classical dynamo. Methods. We find that the characteristic X magnetic field polarization in the plane of the sky, found in edge-on spiral galaxies, can develop magnetohydromagnetically from an initial disk magnetic field combined with wind and rotation. The rotation measure develops a corresponding X distribution in sign, but this distribution is not a universal behavior because it depends primarily on the velocity field. We use Cauchy evolution of an initial magnetic field to find the field at some later time. Results. A battery mechanism that requires the current to always flow out of a galaxy has been recently suggested. This contrasts with the conclusions of this paper. Conclusions. Either explanation has significant consequences for the structure of a spiral galaxy. If the battery mechanism applies, then we have a new method of producing a magnetic field independent of the traditional dynamo. If, however, the flow mechanism applies, then constraints concerning the presence and nature of a galactic wind, together with the signature of the mean radial magnetic field, can be inferred.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
