Hyposulfidic material (WRB 2022 Ch 3.3.9): same inorganic sulfidic S and field pH as hypersulfidic but does NOT consist of hypersulfidic (criterion 3 – does not acidify to pH < 4 on aerobic incubation, usually self-neutralised by carbonate). Reachable from v0.9.128: when incubation_ph is measured, a sulfidic + pH>=4 layer that stays >= 4 on incubation is the set-complement of hypersulfidic_material and is reported here. Without an incubation pH the two cannot be told apart, so this returns empty (the layer is reported as potential hypersulfidic instead).
