An isotopic reconstruction of diet and origins in an 18th-century mass burial site \nat the Fortress of Louisbourg, Nova Scotia
Bibliographic record
Abstract
The Fortress of Louisbourg, on the east coast of Cape Breton, played an important role in the 18th-century colonial history of North America. In 2006, a mass burial was discovered on nearby Rochefort Point. From the historical and archaeological evidence, it is believed the remains are of New England garrison members who died at the Fortress in the winter of 1745-46. To investigate this hypothesis, isotopic analysis was conducted on the individuals’ skeletal remains and on faunal remains from the Fortress. While the dietary reconstruction revealed a great deal of isotopic variability, most individuals subsisted on C₃ based foods. The ⁸⁷Sr/⁸⁶Sr analysis was inconclusive, however, the lack of marine diets and non-French δ¹⁸O values suggests the mass burial individuals were not Louisbourg residents. Furthermore, the δ¹⁸O values suggest possible origins in New England which lends further support to the hypothesis that the mass burial individuals were members of the 1745 New England garrison.

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.
