Abstract
The National Research Council of Canada's (NRC) Kibble balance contributes to the determination of the Consensus Value of the kilogram through participation in periodic key comparisons. This paper provides an overview of the Consensus Value of the kilogram and the realisation and dissemination of mass within the present phase of traceability through it. Description of NRC's participation in international comparisons used to calculate the Consensus Value is detailed, including methods to operate the Kibble balance, major uncertainties, and the evolution of key supporting measurements. The potential benefits of using a digital twin to optimise Kibble balance experiments and of digital comparisons to evaluate the equivalence of realisation experiments and determine the Consensus Value of the kilogram are also discussed. We offer perspectives on the possible future landscape of mass metrology once the use of individual realisations of the kilogram has been sanctioned and the final phase of dissemination from the Planck constant that began with redefinition of the SI in 2019 is reached.

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
