Abstract
This article analyses the use of dilatometry to assess the durability of load-bearing clay brick masonry in a century home in Toronto (Canada). The building had recently undergone the addition of medium density closed-cell polyurethane spray-applied foam insulation on all interior sides of the exterior clay brick load-bearing walls, increasing the insulating value in areas to RSI 7.9 m 2 K/W, on average, from the original RSI 0.5 m 2 K/W, on average. The critical moisture content (saturation degree) of representative samples from the building were compared with values obtained from frost dilatometry testing. The later indicate critical moisture content for freeze–thaw. The frost dilatometry method was furthered by studying three-dimensional testing, rather than the traditional two-dimensional approach. The results showed the brick masonry in the study building are at a relatively low risk of freeze–thaw damage thanks to good resistance of freeze–thaw of the subject brick masonry and low wetting potential of the brick masonry on site. This further strengthens the need for good water shedding characteristics.

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
