\description{
Detects whether GSR/EDA, heart-rate, engagement-dial, and TTL channels are
present and whether they appear active. A channel can be present but inactive
when validity flags are zero or the signal contains only zeros or missing
values. For each signal family, \code{summary_column} identifies the primary
column used for the reported minimum and maximum values.
