Abstract
Hominin footprints are rare in eastern Africa and known from the Laetoli (Tanzania), Ileret (Kenya), and Melka Kunture (Ethiopia) areas. The prints were made by Australopithecus afarensis, Homo erectus, and Homo heidelbergensis. Their study is an important source of information regarding hominin body size, anatomy, positional behavior, and locomotion biomechanics. The most-known and best-studied examples are the 3.66-Ma Australopithecus afarensis footprint trackways at Laetoli, which represent the oldest known record of hominin bipedalism in Africa. The footprints occur in a volcanic tuff sequence, which was originally deposited as melilite nephelinite ash. Recent excavations show that this valuable paleoanthropological site is slowly disappearing as a result of surface diagenetic processes. Preservation of the footprints is essential and urgently needed.

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 it
