Abstract
Acer saccharum is a large, deciduous tree, commonly reaching heights of 20–35 meters with a broad, rounded crown and a strong central trunk. Its root system is deep and extensive, supporting its longevity and drought resistance. The bark is grayish-brown, initially smooth, but developing vertical fissures and shaggy plates with age. Leaves are opposite, simple, and palmately lobed with 5 distinct, deep lobes; blades are 8–15 cm long and wide, dark green above and paler below, turning brilliant shades of yellow, orange, or red in autumn. Flowers are small, yellow-green, and appear in pendulous clusters (corymbs) before leaf-out in early spring; each flower has five petals and is functionally unisexual, with trees often monoecious or dioecious. The fruit is a paired samara, each wing 2–3 cm long, maturing from green to brown in late summer. Sugar maple is native to the hardwood forests of eastern North America, from southern Canada through the northeastern U.S. and extending into the eastern edge of South Dakota. It is mainly found as an ornamental or planted in windbreaks throughout the state.

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.
