Abstract
A comparative survey of MS and M2 grade particleboard from two different Canadian manufacturers was conducted to quantify the distinction between grades and the consistency in quality of products marketed as M2 or MS for use as ready-to-assemble (RTA) modular furniture components. A total of 20 full-sized 4- by 8-foot (1.22 by 2.44 m) sheets were intensively sampled for density parameters (ovendry, vertical density profile), internal bond strength, flexural strength and stiffness (modulus of rupture [MOR] and modulus of elasticity [MOE]), and face and edge screw withdrawal resistance (SWR). As expected, the MS grade particleboards were lower in density and strength properties; however, the quality of both grades were greatly dependent on the manufacturer. The M2 grade of panels from one manufacturer were similar to or had lower properties than the MS grade from the other. Both grades of panel from press line A met ANSI A208.1 minimum standards for face SWR, MOR, and MOE, whereas both grades of panels from press line B were borderline or below their respective standards. MS grade panels from both press lines were below ANSI minimum edge SWR of 800 N, which could compromise the suitability of the product for RTA furniture fixed with screws.

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
