Abstract
A variable-frequency light ray (VF ray) is a new concept in optics; it is a ray that is monochromatic at every point of the path (no frequency spread) but its frequency changes along the path due to interactions occurring along that path. For example, the frequency of the light ray can be affected by gravitational time dilation, reflection from a moving mirror, or coherent Raman scattering. Since the Fermat principle of least time (PLT) implicitly assumes that the frequency of the light ray is an irrelevant constant, the PLT-based geometrical optics is insufficient to handle propagation of VF rays. In this paper, we derive a new extremum principle (NEP) that is sensitive to changes of frequency along the path of the light ray and constitutes a basis for geometrical optics of VF rays. The NEP is derived directly from the principle of least action applied to the quantized electromagnetic field associated with the light ray propagating in a vacuum or in a transparent material medium in the presence of the gravitational field. The relationship between the NEP, the classical version of the Fermat principle, and the general relativistic generalization of the Fermat principle (the extremum principle for null geodesics) is discussed in detail. Applications of the NEP are suggested in the nonrelativistic, special relativistic, and general relativistic regimes. PACS Nos.: 42.15-i, 12.20-m, 04.20-q

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.
