PINN-ECS-HAB: Physics-Informed Neural Network with Strong PDE Residuals and a Learnable Cyst-Germination Source for Forecasting Harmful Algal Blooms in the East China Sea (code )

v1.2.0 (2026-08-11): land mask corrected to Natural Earth 10m (23.35% land; the v1.1 archive embedded a synthetic coastline at 9.85%). All models, baselines, metrics, tables, and figures in the manuscript were retrained / recomputed on the corrected schema. Code now includes the make_fig7_goci.py generator and unified Arial figure typography. See README.md section 0 for the v1.2 land-mask correction.
