Abstract
Abstract Observations of physical processes on the open-coast tidal flats along the southwestern coast of Korea show that tidal modulation of wave energy, as a result of changing water depth, produces composite storm beds that should be distinct from the classic storm beds that characterize wave-dominated shorefaces and shelves with small tides. Storms (typhoons) during the low-energy summer generate muddy storm beds that superficially resemble the upward-thinning tidal rhythmites that form between spring and neap tides. Sandy, winter storm beds contain both falling-tide deposits that consist of decreasing-energy facies successions and rising-tide deposits that consist of increasing-energy facies successions. Over most of the tidal flat, bioturbation levels are low, even in the summer mud deposits, because of episodic high-energy conditions and high rates of sedimentation. Bimodal levels of bioturbation (negligible in the thin intra-storm, low-tide mud drapes versus more intense in inter-storm, fair-weather deposits) should characterize deposits formed on open-coast tidal flats. The style of bioturbation on the lower flat is similar to that reported from upper shorefaces, whereas the inner flat contains a mixed Skolithos-Cruziana assemblage that is much less diverse than that found in shelf deposits. These observations show that a spectrum of storm-bed types is to be expected between wave-dominated (i.e., shoreface and shelf) and tide-dominated (i.e., tidal-flat) settings.

Full frame distilled prediction
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
