The Acropolis of Kaminaljuyú, Guatemala: recovering a Lost Excavation
Bibliographic record
Abstract
In 2003, our project focused on recovering data from a «lost excavation», a deep but unpublished series of probings by Gustavo Espinoza in the Acropolis of Kaminaljuyu. His work, which took place between approximately 1958 and 1962, uncovered a complex layering of floors and talud-tablero structures. To understand this research, we remapped the Acropolis and the Park that contains it, analyzed floors, and defined a paradox: continuous construction that nevertheless shows the introduction of a radically foreign technology of construction, which changes later, during the Late Classic (Amatle) period, to earthen building with cobble matrix. The extreme views of Teotihuacan-no influence from Mexico or massive influence from the same quarter-must be seen as misleading. Portions of the Acropolis can only be understood in terms of historically strong, but perhaps not economically extensive, engagement with Teotihuacan.

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.
