\usage{
stagnic_properties(
  pedon,
  max_top_cm = 100,
  min_redox_pct = 5,
  decay_factor = 3
)
}
\arguments{
\item{pedon}{A \code{\link{PedonRecord}}.}

\item{max_top_cm}{Maximum top depth (cm) of candidate shallow
layers (default 100).}

\item{min_redox_pct}{Minimum redox feature percent in the shallow
layer (default 5).}

\item{decay_factor}{Required factor of redox decrease with depth
(default 3, i.e., deeper redox < shallow / 3).}
}
\value{
A \code{\link{DiagnosticResult}}.
}
\description{
Tests for redoximorphic features driven by perched water. Distinct
from gleyic (groundwater): stagnic features appear in upper layers
AND redox decreases substantially with depth (the perched layer
sits above a slowly permeable subsoil that itself is not
saturated).
