Abstract
Beginning in the 1880s, transportation innovations allowed the City of Los Angeles to expand past natural barriers and develop the vast land beyond the city's core. The cable car and the electric trolley aided the expression of a Victorian residential ideal and urban aesthetic imported into Los Angeles from “back East” and the Midwest. Streetcar suburbs, the earliest form of urban flight, emerged on what were then the outer fringes of the city, initiating perpetual sprawl. While the city's massive growth in the 1920s as well as extensive post–World War II suburbanization cannot be ignored, such development has obscured the much earlier origins of sprawl in the historiography. This paper argues that Victorian Los Angeles instituted trends aimed at low-density, outward growth, which the streetcar enabled, Progressive planners reinforced, and which bore many of the drawbacks associated with modern urban sprawl.

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.
