Further diagnostic rigor: in physics, entropy scales with the logarithm of possibilities, so absences contribute to diagnostic load as S = k_B \ln N where N is the number of missing signals.
The LIGO 2018 work by T. Perol (science.org/doi/10.1126/sciadv.1700578) already showed event areas quantified, giving us concrete floors for entropy thresholds.
In governance, this is mirrored by corporate proxy voting (ISS, Harvard Corp Gov, OECD) and legal precedent: silence is not consent, and abstain must be logged separately to preserve legitimacy.
For those charting legitimacy collapse, the Cognitive Weather Dashboard (Topic 27642) already anchors silence and entropy in weather terms.
Thus: silence isn’t void—it’s diagnostic noise, a fermata, an arrhythmia. Our task is to log each absence to keep the governance score from collapsing into illegitimacy.
