Its causal comparison and falsifiers are unusually explicit, but the existence, stability, controllability, incremental benefit, demand, distinctiveness, and field relevance of the mode remain unverified.","adopter_authorizer":"A shallow-lake mesocosm principal investigator and permit holder, acting with required animal-care, ecological, biosafety, and facility approvals.","scores":{"meaningful_impact":{"score":4,"rationale":"Preserving clear water, oxygen conditions, and multispecies community integrity would be meaningful within the stated mesocosm regime, but no field benefit, prevalence, or effect on water users is established."},"stakeholder_pull":{"score":2,"rationale":"The packet identifies investigators and permit holders but supplies no evidence that facilities, restoration practitioners, communities, or water users currently seek modal control or regard late single-control intervention as a recurring operational problem."},"incremental_advantage":{"score":3,"rationale":"The proposed advantage is concrete—lower risky-mode AUC and ecological loss under an equal disturbance budget versus coordinate-wise and nonlinear nonmodal rivals—but it is entirely hypothetical until the confirmatory comparison succeeds."},"distinctiveness_plausibility":{"score":3,"rationale":"Causally identified control effects, bootstrap-stable mode selection, and a disturbance-matched four-arm test form a distinguishable claim, but prior art is explicitly unsearched and overlap with ecological early-warning, state-space control, and adaptive-restoration methods is unknown."},"technical_implementability":{"score":3,"rationale":"The candidate specifies variables, perturbation ranges, model gates, controls, stopping rules, and minimum confirmatory units, yet implementation requires at least 72 Stage A mesocosms and at least 96 Stage B units, sufficient power and capacity, and unresolved endpoint and mode-selection specifications."},"adoption_authority_feasibility":{"score":4,"rationale":"Authority is clearly bounded to a principal investigator and permit holder operating enclosed mesocosms, with field actions excluded; feasibility remains conditional on obtaining the named approvals and facility capacity."},"evidence_readiness":{"score":4,"rationale":"The staged randomization, held-out prediction gates, bootstrap stability tests, explicit problem and intervention falsifiers, matched rivals, and safety stops provide a strong evidence framework, although the ecological-loss composite and locked mode-selection algorithm are incomplete."},"safety_net_benefit":{"score":2,"rationale":"The proposal could offer a fallback when a threshold-triggered single control acts late, but benefit is confined to an experimental mesocosm regime and no protection of communities, water users, or field ecosystems has been demonstrated."},"scalability":{"score":2,"rationale":"Replication across enclosed units is conceptually possible, but scale-dependent modes, seasonal rotation, facility capacity, organism handling, and the explicit exclusion of field deployment sharply limit demonstrated scalability."}},"score_confidence":"MODERATE","costs":{"first_evidence":{"band_2026_usd":"250K_TO_1M","scope":"Preregister, execute, measure, and analyze the 72-mesocosm Stage A fractional-factorial
