Multi-Probe Event Lab — three witnesses, one verdict

One sample warms through a hidden transition. Three complementary channels watch: a diffraction peak, a Raman shift, a resistance. Slide the temperature and compare their confidence.

Model honesty: three illustrative response channels share one teaching transition at T* = 350 °C. The XRD peak follows a gentle linear thermal drift with a discrete position jump at T*; the Raman mode softens linearly with a discrete shift and slope change at T*; the resistance follows a smooth thermally activated rise with a step at T*. Each channel carries its own fixed-seed noise, so single-channel deviations are deliberately ambiguous — each detector alone reports at most “possible,” while the cross-channel reading strengthens only when all three complementary signals deviate together. Coincident anomalies strengthen an event assignment; they do not by themselves prove causality or exclude a shared systematic artifact — the alignment audit in the article is the other half of the argument. Curves, magnitudes and the transition itself are schematic teaching constructions, not data for any real material; real multi-probe work must also pass the time/temperature/space alignment audit described in the article.
