# Main scientific corrections

1. Restored a complete five-compartment human-snail fractional model.
2. Replaced the inconsistent recovered equation by the population-balanced inflow `delta*A`.
3. Used `beta2` consistently as snail mortality in both snail equations.
4. Added the Caputo definition, positivity, boundedness, disease-free equilibrium, reproduction number, and local stability.
5. Implemented the Diethelm-Ford-Freed fractional Adams predictor-corrector method.
6. Reframed the neural method accurately as a supervised trajectory surrogate rather than an independent differential-equation solver.
7. Added a reproducible two-hidden-layer RBF-SCG implementation, fixed seed, data split, metrics, CSV data, and figures.
8. Rewrote the introduction, abstract, results, discussion, conclusions, declarations, and bibliography.
