Abstract
Abstract We propose a simple and effective approach to simultaneously co‐amplify both cytochrome b and D‐loop fragments to evaluate DNA preservation and to monitor possible contaminations in the analysis of degraded animal DNA samples. We have applied this approach to over 200 ancient salmon samples and 25 ancient whale DNA samples, clearly demonstrating its multiple benefits for analysis of degraded DNA samples, and the ease in which co‐amplification can be optimized for different taxa. This simple, cost‐efficient and genomic DNA‐saving approach can be used routinely in the analysis of minute and degraded DNA samples in wildlife forensics, food inspection, conservation biology and ancient faunal remains.

Full frame distilled prediction
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
