Abstract
Abstract. The enchytraeid Grania americana has a dorsal statocyst within the peristomium. It is connected to the anterior end of the cerebral ganglion. Transmission electron and light microscopy were used to study this region of the head. The statocyst is divided into four membrane‐bound chambers; each contains an electron dense statolith surrounded by numerous sensory cilia, so that it is a multi‐chambered or compound statocyst. Cilia within the statocyst possess a 9 × 2 + 0 microtubule arrangement, with one of the doublets in a central position. All cilia that were observed in the statocyst and in the cerebral ganglion had this arrangement of microtubules. This is the first description of a statocyst in the Clitellata. The statocyst of G. americana is compared to those described in polychaetes and may provide useful information for phylogenetic and taxonomic studies of the genus, of clitellates, and of annelids.

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
