Abstract
The study site is a coastal spit located in the Englishman River estuary, located at Parksville, British Columbia approximately 80 km west of Vancouver as shown in Figure 1. In this paper, we present a holistic approach to evaluating nature-based solutions and assessing coastal processes of a mixed sediment shoreline by integrating coastal process modelling using XBeach (Deltares, 2018) with geomorphic assessment This study applied a hybrid approach using both XBeach 2D which has been shown to have good quantitative skill in predicting storm response of sandy beaches and a modified 1D version, XBeach-G, which has been applied with some success to modelling uniform gravel beaches (McCall et al, 2014). The 2D (sand) and 1D (gravel) versions were applied in the surf beat mode and non- hydrostatic mode, respectively.

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
