A complete wave bundle is composed of three distinctive rippled intervals: (1) a basal interval consisting of landward-dipping, ripple cross lamination that is formed in response to a combined-flow regime during rising tide; (2) a middle interval with symmetrical buildup of wave-ripple cross lamination that is deposited during high tide when currents are weak and oscillatory motion is dominant; and (3) a top interval having seaward-dipping, ripple cross lamination that is formed as a result of a combined-flow regime during falling tide. The formation of such wave bundles results from the interaction of waves and reversing tidal currents over a single tidal cycle. Therefore, the presence of wave bundles indicates a very specific depositional environment—an area with significant tides, weak tidal currents and considerable wave energy. The finding of such structures may indicate the presence of open-coast tidal flats (i.e., wave-dominated tidal flats) in ancient deposits.

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.
