Reply to the discussion of the reply by R.L. Romer and U. Kroner on “Geochemical signature of Ordovician Mn-rich sedimentary rocks on the Avalonian shelf” <sup>1</sup>Appears in the Canadian Journal of Earth Sciences, <b>49</b>(11): 1372–1377 [doi:10.1139/e2012-049].

Abstract
Romer and Kroner (2012) stated “the core of the Harlech Dome (i) in part is made up of Ordovician deposits and (ii) contains tectonic repetitions”. In their comment, Schofield et al. (this issue) distort this statement and state that (i) we claim the entire sedimentary sequence of the Harlech Dome is Ordovician and (ii) we misinterpreted their zircon data. We disagree. In our reply, we demonstrate that the argumentation of Schofield et al. (this issue) is driven by circular argumentation and that their use and interpretation of U–Pb zircon data is inadequate.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
