Permanence classification: uniform_permanence_by_paper_theorem. Siphons (species indices s,a,b,c): [[], [1, 3], [2, 3], [1, 2, 3]]. Overlap identity residual: 0; at shared zero mode: 0. Independent parameter-box margins: ['5601/101000', '8701/25250']. Complete disease-free Jacobian unchanged under eta1 obstruction: True. Normalized weights: {'ru': '1', 'rv': '191/84', 'rj': '1', 'k': 1, 'fibre_growth_lower_bounds': ['47/5', '267/3820', '2/5'], 'product_floor': None}. No numerical universal species floor is computed or inferred from trajectories.
