\title{Test for anthric / pretic / hortic / plaggic / terric / irragric
horizon properties (full diagnostic)}
\usage{

\description{
WRB 2022 specifies five anthropogenic surface horizons that are all
diagnostic for Anthrosols. Rather than relying on the designation
pattern alone, this predicate also checks property-based evidence:
a surface horizon (top_cm <= 5) with elevated dark colour
(Munsell value <= 4 moist) AND elevated plant-available P
(\code{p_mehlich3_mg_kg} >= 50) AND minimum thickness 20 cm.
Either path (designation OR property-based) qualifies.
