Abstract

fetched live from OpenAlex

A Chara exhibiting extreme morphological features including stipulodes, spine cells, and bracteoles is described and subjected to barcoding procedures to determine whether it belongs to the Chara contraria group or the C. hispida group. MatK barcoding clearly placed it in the C. contraria clade which was consistent with gametangial morphology, but not stipulode, spine cell and bracteole morphology. The specimen was determined to be included in the Chara contraria var. hispidula taxon, not previously reported or described for Newfoundland, Canada, or the USA.

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.

How this classification was reachedexpand

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.
