Self-intersection by JDK repairs geometries (makeValid + buffer 0 to remove self-intersections), applies "Multipart to singleparts" to isolate non-conforming geometries, creates a Surface_Ha = $area / 10000 field, then removes features whose 0 <= Surface_Ha < 0.25 ha (upper bound excluded), producing a deleted-polygons layer. Graphical interface plus a Processing algorithm (Model designer / batch / qgis_process). Designed for geometric quality control (land, cadastre, agriculture, forestry, EUDR/RA).
