Abstract
Abstract Molecular techniques offer sensitive, specific, noninvasive monitoring of target species from a variety of environmental samples. We recently developed a CRISPR‐Cas‐based eDNA assay for rapid single‐species detection as a route to a simple, cost‐effective biosensor device. CRISPR‐Cas‐based diagnostic assays use isothermal conditions in combination with a highly specific sequence recognition system. This CRISPR‐Cas assay was designed to target Salmo salar , and we previously demonstrated its utility in eDNA samples from sites in Ireland. The aim of this study was to validate our assay in two larger sample sets from Canada ( n = 16/ n = 63) in comparison with an independent S. salar qPCR assay. We demonstrate that overall, the CRISPR‐Cas assay performs similarly to qPCR for assessing the presence or absence of S. salar from eDNA and provides a viable alternative approach where qPCR assay design and application have proven to be challenging.

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
