Abstract
The deterioration of jointing compounds used to seal building joints has been thoroughly investigated whereas that of relating the consequences of failure of jointing products, whilst generally understood, has not been studied in depth, in particular in respect to loss in watertightness. Jointing products age due to natural weathering effects that, in time, lead to deficiencies in the product and, in turn, lead to the local failure of the jointing system. Deficiencies may also occur from design faults or improper installation. Water penetration at deficiencies may lead to a number of different deteriorating effects on the building fabric that may induce failure of other envelope components or the loss in adhesion of the sealant. Joints are also subjected to significant wind-driven rain loads in particular atop multi-storey buildings located along an exposed coastline. To what extent are joints vulnerable to water leakage when subjected to a rain event, such as a typhoon, as might be experienced in Japan, or a hurricane as in North America? The question of fault tolerance in jointing systems has not yet been broadly explored. An overview is provided on the nature of water entry at sealed joints of cladding systems and information is also presented on a study related to water penetration at joints. Small deficiencies in jointing systems may lead to significant water entry when such joints are subjected to severe wind-driven rain loads.

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
