Abstract
Eclipsing binary stars have intrigued astronomers for centuries. To study them is to journey through discoveries and innovations. One of the earliest significant insights came in 1783 when 18-year-old John Goodricke boldly proposed that the periodic dimming of the star Algol, which he and his friend and mentor Edward Pigott had carefully studied, was due to an eclipse by a large dark body revolving about Algol. The communication so impressed the Royal Society of London that Goodricke was awarded the prestigious Copley medal that same year. As observational techniques evolved and photographic photometry developed, the quality as well as the quantity of data increased and by the early 20th century, gravitational physics had matured sufficiently that Henry Norris Russell and Harlow Shapley could provide quantitative procedures for finding the properties of stars in eclipsing systems to capitalize on them, an example of a path characterized by Russell (1948) as the Royal Road of Eclipses. Over the following decades, deeper understanding of the physics governing systems of short-period binary stars led to more sophisticated treatments. Zdenêc Kopal and other researchers expanded the analytical framework and initiated more rigorous studies of the internal and orbital dynamics of these systems. The advent of high-speed computing in the 1970s revolutionized the field by enabling simulations of increasing complexity. Continued computational and analytical improvements, coupled with the explosive growth in observational data from wide-field surveys culminating in the Gaia mission, are propelling eclipsing binary research into a new era. We have now both the computational power and the observational depth to probe stellar structure and evolution with unprecedented precision. This presentation highlights key milestones in the study of eclipsing binaries, innovative capabilities in data acquisition and modeling, and the promising role of high-precision infrared photometry. Particular attention will be paid to the enhanced precision attainable through the use of improved passbands for ground-based infrared photometry at local observatories, and to the extended functionalities of the Wilson-Devinney modeling framework, and complementary analytical tools and programs.

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.
