Abstract
Different studies have proposed either Pacific or in situ models for the tectonic evolution of the Caribbean Plate. Pacific model proponents, in general, extrapolate data obtained at the northern, eastern, and southern boundaries of the Caribbean Plate to indicate the arrival of the Caribbean Plate from the west relative to North and South America since the Late Cretaceous. In contrast, for the same period of time, in situ model proponents interpret other data as evidence of west -east extension of the western or central Caribbean and the possible preservation of Atlantic or proto-Caribbean lithosphere within present Caribbean Plate boundaries. The limitations of both models in explaining some parts of the geological record provide the rationale for considering further alternatives. The 'Pirate' model of Caribbean tectonics is a new hypothesis for the Cenozoic era that involves: (1) microplate capture in the western Caribbean of blocks derived from adjacent parts of North and South America, and (2) counter-clockwise rotation of the Caribbean Plate relative to North and South America. Whereas new Caribbean lithosphere is hypothesized to have entered Middle America from the west in the Pacific model, and from depth in the in situ model, the Pirate model postulates that new Caribbean lithosphere entered the western Caribbean region from the north or south.

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
