Abstract
Abstract: The internal architecture and external form of fluvial channel bodies is governed by both intrinsic and extrinsic controls. Extrinsic controls such as climate, eustasy, and tectonism are believed to have modest effects on channel-body types and geometries in high-subsidence settings. The effects of climate are particularly cryptic in high-accommodation settings and have proven extremely difficult to separate from other extrinsic controls such as tectonics and eustasy. The thick successions preserved in such basins have the potential to be relatively stratigraphically complete and are, therefore, valuable for interpreting basin evolution. This study documents the external geometry and internal architectural styles of fluvial channel bodies in a spectacularly exposed, 7-km-thick, Mississippian–Permian section from the Cumberland Basin, Atlantic Canada. Four fluvial styles are recognized: perennial, strongly seasonal, ephemeral, and fixed. Fluvial styles are not randomly distributed throughout the stratigraphic succession; instead discrete stratigraphic intervals consist of predominantly one type of fluvial style. Four stratigraphic intervals (E1–E4) in which strongly seasonal fluvial styles are predominant are recognized and alternate with intervals that are characterized by either perennial or ephemeral deposits. This suggests that a coherent record of climate change as manifested by changes in precipitation and runoff regime is recorded in the internal architecture of sandbodies.

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
