[ Metric reference ]

Cohort Transfer Slope

A slope for how PictoClarity Score changes across modeled birth cohorts.

[ Code ]

CTS

[ 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.
