Abstract
nalyses of new data presented in scientific publications on the studies results of the Ediacaran strata in Ukraine and worldwide in terms of sedimentation conditions, sedimentation features and biogenic fossils have been carried out. The article contains materials on the summarising of the data on the results of recent research on stratotype Ediacaran sections in South Australia (Ediacaran Hills), the southeastern part of Newfoundland (Avalon Peninsula) and the White Sea coast. The advanced precision research methods used to develop issues of stratigraphy, sedimentology, geochemistry, paleontology, etc. have been highlighted. The main stages of sedimentation and evolutionary processes in the Ediacaran ecosystem of Volyno-Podillia have been shown and the influence of facial conditions on the taxonomic composition of biotic associations, spatial heterogeneity of communities and morphological features of fossils have been studied. The presence of some Avalonian, Ediacaran – White Sea and Namibian biota representatives has been revealed in the Podillia Ediacaran strata. The analysis of the taxonomic diversity of the studied biotic associations and the ‘absolute’ age data of the maximum prosperity of the Ediacaran biota (established in the Lomoziv and Yampil beds) allows to consider the Podilia biota of the Mohyliv Formation to be younger than the Avalonian association, but slightly older than the White Sea and South Australian ones.

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.
