Abstract
À Saint-Simon-sur-Mer, sur la rive sud de l’estuaire maritime du Saint-Laurent,\n\t\t\t\t l’estran argileux est en grande partie recouvert par des dallages et des cordons de blocs de taille,\n\t\t\t\t de forme et de nature variées. Représentatif d’une large portion du littoral des deux rives de\n\t\t\t\t l’estuaire, cet estran est ici caractérisé pour son originalité. La nature lithologique des cailloux\n\t\t\t\t comprend des éléments locaux ainsi que des erratiques lointains provenant des Appalaches, au\n\t\t\t\t sud, et du Bouclier laurentidien, au nord. Ces derniers ont d’abord été déplacés vers la vallée\n\t\t\t\t du Saint-Laurent par les glaciers du Wisconsinien (Weichselien) avant d’être transportés et\n\t\t\t\t délestés dans la mer postglaciaire (Mer de Goldthwait) par des icebergs et des radeaux de glace\n\t\t\t\t annuelle. Certains erratiques, dont les cailloux de dolomie à stromatolites d’âge Protérozoïque,\n\t\t\t\t ont été déplacés sur des distances excédant 400 km. L’érosion des dépôts argileux en bordure\n\t\t\t\t des crêtes rocheuses appalachiennes longeant le littoral à Saint-Simon-sur-Mer a laissé derrière\n\t\t\t\t la fraction grossière. Les cailloux ont, par la suite, été concentrés par les glaces annuelles, dans\n\t\t\t\t la zone intertidale et infratidale adjacente, puis partiellement enfoncés dans le substrat argileux.\n\t\t\t\t Ils forment aujourd’hui des dallages et des cordons. Par la suite, des apports locaux de blocs\n\t\t\t\t provenant du démantèlement des crêtes rocheuses se sont ajoutés au résidu grossier (lag) laissé\n\t\t\t\t derrière par l’érosion de l’argile par les vagues et les courants. De nos jours, les dallages de\n\t\t\t\t cailloux forment une carapace qui entrave et retarde l’érosion du substrat argileux.\n\n\t\t\t\t A typical clayed tidal flat covered by boulder pavements, Lower St. Lawrence\n\t\t\t\t estuary (Québec, Canada). At Saint-Simon-sur-Mer along the south shore of the Lower\n\t\t\t\t St.Lawrence estuary, the clayed tidal flat is largely covered by stone pavements and ridges of\n\t\t\t\t boulders of various sizes, forms, and lithologies. Common and typical feature of the shoreline\n\t\t\t\t on both sides of the estuary, this kind of tidal flat is original. Boulder lithologies are mixed\n\t\t\t\t including far-distance erratics from the Appalachians and the Laurentidian Shield, and clasts\n\t\t\t\t from the nearby coastal area. Far-distance erratics were first transported to the St. Lawrence\n\t\t\t\t valley by the Wisconsinan glaciers before being ice-rafted by icebergs and sea ice into the\n\t\t\t\t postglacial sea (Goldthwait Sea). Some erratics have been moved over 400 km. Erosion of the\n\t\t\t\t coastal marine clay deposits during the Holocene produced boulder lags. The exhumed clasts\n\t\t\t\t were subsequently moved and concentrated by shore ice in the tidal zone before being driven\n\t\t\t\t down into the clayed substrate. They form today boulder pavements and ridges. Afterwards\n\t\t\t\t there have been additions of local blocks from the Appalachian ridges bordering the south shore\n\t\t\t\t of the estuary at Saint-Simon-sur-Mer. Today, this boulder intertidal clayed substrate is largely\n\t\t\t\t protected from erosion by waves and currents.

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
