Abstract
We report the characterization of 3 new repetitive sequences from the bivalve mollusc Mytilus galloprovincialis, designated Mg1, Mg2, and Mg3, with monomer lengths of 169, 260, and 70 bp, respectively. The 3 repeats together constitute approximately 7.8% of the M. galloprovincialis genome and were found, together with ApaI-type 2 repeats, inside the introns of 2 genes of the HSP70 family, hsc70 and hsc71. Both the monomer length and the genomic content of the repeats indicate satellite sequences. The Mg1 repetitive region and its flanking sequences exhibit significant homology to CvE, a member of the Pearl family of mobile elements found in the eastern oyster (Crassostrea virginica). Thus, the whole homologous region is designated MgE, the first putative transposable element characterized in M. galloprovincialis. The ApaI, Mg2, and Mg3 repeats are continuously arranged inside the introns of both the hsc70 and hsc71 genes. The presence of perfect inverted repeats flanking the ApaI-Mg2-Mg3 repetitive region, as well as a sequence analysis of the repeats, indicates a transposition-like insertion of this region. The genes of the HSP70 family are highly conserved, and the presence of repetitive DNA or of mobile elements inside their introns is reported here for the first time.

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
