Abstract

fetched live from OpenAlex

C values, suggesting that they catabolized more fat than unsuccessful females. Even though we were unable to link ocean habitat use to migration or reproductive success, we found several patterns of isotopic increases due to protein and lipid catabolism. These findings have implications for reinterpreting past and future studies using stable isotope values collected from migrating or dead salmon and, by extension, other animals.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
