[ Formula structure ]
The public formula describes structure.
- CTS = abs(PCS_oldest - PCS_youngest) / n
- Private calibration, weighting, and evidence ranking stay protected.
[ How to read it ]
The metric supports screening, not certification.
- A high CTS means clarity changes materially across cohorts.
- A low CTS means the modeled transfer profile is comparatively stable across cohorts.
- Every reading depends on declared context and evidence quality.
- Human validation remains first-order evidence.
