Decoded vocabulary readouts for the current trace and layer
Select	Decoded token	Prevalence index	Intensity	Layer profile

Prevalence and layer intensity are relative display indices. Darker profile cells show higher relative values. The symbol ␠ marks a leading space in a decoded-token name or a whitespace-only transcript token. The artifact provides no calibrated probabilities.

How to read these measures

The prevalence index is normalized to the most frequent tracked row in this trace; layer intensity is artifact-normalized. Neither is calibrated confidence.
