PRECLASSIC PLACEMAKING AT YAXNOHCAH, MEXICO: A VIEW FROM THE GRAZIA AND HELENA COMPLEXES
Bibliographic record
Abstract
Abstract Archaeological excavations at Yaxnohcah have revealed a long sequence of sedentary occupation, from 1000 b.c. to a.d. 1400, with dynamic periods of growth occurring during the Middle (1000–400 b.c.) and Late Preclassic (400 b.c.–a.d. 200). Two of these complexes, Grazia and Helena, serve as case studies that reveal the transformative processes of this period, illustrating site evolution on a larger scale. The Grazia platform probably began as a residential area in the Middle Preclassic and acquired an increasingly public character throughout subsequent modifications, culminating in the construction of a triadic temple platform and a ballcourt. A long sequence of fire rituals and altars show the importance of the Grazia complex as a center for collective ritual. Helena also features Middle Preclassic domestic constructions, but was transformed into a ballcourt platform during the transition to the Late Preclassic. Both cases show that Yaxnohcah was founded as a widespread, loosely integrated settlement in the Middle Preclassic and evolved into a formally and centralized network of communities with their respective nodal centers in the Late Preclassic period. Placemaking and the rise of monumentality played an important role in this transformation and reflect the particular forms of community integration.

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.
