Why this work is in the frame

A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.

No Canadian affiliation. An affiliation-only frame, the usual design, would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract

fetched live from OpenAlex

We present a Bayesian maximum likelihood analysis of three concatenated gene sequences from a wide, but sparse, collection of craniiform brachiopods. The results fall into five clades, four with Novocrania-like and one with Neoancistrocrania-like morphology. The Neoancistrocrania-like clade unites some specimens from near Japan with authentic Neoancistrocrania from the Norfolk Ridge (SW Pacific) and appears, in this analysis, to be the sister group of the North Atlantic-Western Mediterranean clade. The five Novocrania-like clades comprise specimens from (1) the North Atlantic and West Mediterranean including the Tyrrhenian Sea; (2) the East Mediterranean and Caribbean; (3) the Weddell Sea, the southeast Pacific and near Japan; (4) near Vancouver Island (east Pacific) and near Taiwan; and (5) New Zealand (North Island). In addition, one technically dubious result appears to associate a specimen from the Campbell Plateau with the North Atlantic clade. The East Mediterranean-Caribbean clade may reflect ancestral dispersal via Tethys. Reasons are given for disregarding the previous informal attribution to Craniscus japonicus of Japanese Novocrania-like specimens.

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.
