\usage{
extract_gazepoint_hrv_asymmetry(
  dat,
  ibi_col = "IBI",
  group_cols = NULL,
  zero_tolerance = 0
)
}
\arguments{
\item{dat}{A data frame containing IBI/RR intervals.}

\item{ibi_col}{Numeric IBI/RR interval column.}

\item{group_cols}{Optional grouping columns.}

\item{zero_tolerance}{Absolute change below which interval differences are
treated as zero.}
}
\value{
A list with \code{overview}, \code{features}, \code{run_table}, and \code{settings}.
}
\description{
Computes dependency-light heart-rate asymmetry descriptors from IBI/RR
intervals, including acceleration/deceleration proportions, signed run
summaries, and Guzik-style squared-difference asymmetry.
}
\details{
Positive IBI/RR differences are treated as decelerations because the heart
period lengthens. Negative IBI/RR differences are treated as accelerations.
