Abstract
Test results on the structural performance of rounded dovetail connections (RDCs) under different loading conditions are reported. The RDCs are a versatile connection concept that is mainly used to transfer shear, but its geometry enables it to also resist other loading conditions. The connection capacity and the design load of two different connection configurations (single and double dovetail) produced from kiln-dried western hemlock (Tsuga heterophylla) in shear, tension, and bending tests were evaluated using analysis of variance. The shear tests demonstrated that RDC show linear elastic behaviour until they reach a load that leads to crack development. Connections with a single dovetail configuration provided higher tension capacity, while not showing significantly different structural performance than the double dovetail configuration under other loading conditions. The work demonstrated that RDCs also have considerable tension and bending resistance.

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
