Bibliographic record
Abstract
ABSTRACT Palaeo‐sea‐level estimation and palaeo‐shoreline mapping of the Fanga ‘Uta/Fanga Kakau Lagoons on Tongatapu was undertaken by W.R. Dickinson in 1999. First Lapita settlement of Tonga occurred by c.2850 calBP on what is today the Nukuleka Peninsula, at the entrance to this lagoon system. Additional archaeological survey, excavation and LiDAR data challenge the 1999 portrayal of Nukuleka as a contracted peninsula tied to the Tongatapu mainland. Rather, first landfall took place on the coastal flats and shoreline of an elongate palaeo‐islet formed from the remnants of an earlier mid‐Holocene sandspit. The recovery of decorated Lapita ceramics in several contexts within a Lapita‐age tidal range implies the presence of stilt‐house occupation, as documented for the Lapita cultural complex in Near Oceania.

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.
