Inspection found no permanent line fault, but the remaining transformer is still running hot, several voltage regulators have not completed calibration, and thousands of thermostats, pumps, and commercial refrigeration units are waiting to restart. Operators estimate that the accumulated demand is substantially higher than the district’s ordinary steady load. During a brief test, reconnecting one large feeder produced a sharp current surge and unstable voltage before protection equipment opened the circuit again. The evening temperature is rising, so demand is continuing to accumulate while crews work. Engineers agree that energizing every feeder and allowing all customers to resume normal consumption simultaneously would probably recreate the overload and voltage collapse that triggered the shutdown. The utility must determine how to return the district to service without losing the substation again.","scenario_title":"Heat-Stressed Substation After a District Blackout","vocabulary_separation_audit":"Uses grid-specific language such as feeders, regulators, current surge, and voltage collapse; it does not reuse the transfer domain's biological or water-quality vocabulary."},{"alternative_route_blocks":[],"case_id":"E14A037__TRANSFER","case_type":"TRANSFER_POSITIVE","domain":"Recirculating aquaculture","intended_route_id":"B1","omitted_condition_id":null,"remedy_leakage_audit":"The scenario presents the husbandry risk without recommending a feeding, stocking, or filtration strategy.","route_evidence":[{"condition_id":"ext001_controlled_reentry_a02","intended_status":"SATISFIED","scenario_evidence":"Staff expect that immediately returning all fish and feed inputs to normal levels would cause another ammonia rise and oxygen crash."}],"scenario_text":"A recirculating trout hatchery has stabilized after a pump outage killed much of the bacterial community in its biofilter. Emergency aeration kept most fish alive, and water is again circulating, but ammonia remains near the upper safe limit and laboratory samples show that the nitrifying population is only beginning to recover. For three days, several tanks have been held at reduced biomass in temporary raceways, and feeding has been minimal. The surviving trout are increasingly stressed in the crowded temporary space, while production managers want the main system back at its usual stocking and feeding levels before the next shipment arrives. Hatchery biologists calculate that the present filter can process only a fraction of the waste generated during normal operations. They expect that returning every fish and the full feed ration immediately would drive ammonia upward and consume dissolved oxygen, recreating the lethal water-quality crash that followed the outage. A decision is needed before the temporary raceways exceed their safe capacity.","scenario_title":"Hatchery Biofilter Following a Pump Outage","vocabulary_separation_audit":"The aquaculture setting and terms—trout, biofilter, biomass, ammonia, nitrifying population, and dissolved oxygen—are substantially different from the electrical-distribution vocabulary of the direct case."},{"alternative_route_blocks":[],"case_id":"E14A037__NEAR_MISS","case_type":"ONE_LITERAL_NEAR_MISS","domain":"Recirculating aquaculture","intended_route_id":"B1","omitted_condition_id":"ext001_controlled_reentry_a02","remedy_leakage_audit":"The scenario reports recovery measurements and an operational decision point but does not recommend an intervention or restoration pattern.","route_evidence":[{"condition_id":"ext001_controlled_reentry_a02","intended_status":"CONTRADICTED","scenario_evidence":"Repeated full-load trials and independent testing establish that normal stocking and feeding can resume immediately without renewed ammonia accumulation, oxygen instability, or recurrence of the outage-related loss."}],"scenario_text":"A recirculating trout hatchery is preparing to resume normal production after a pump outage damaged its biofilter six weeks ago. Several tanks remain in temporary raceways, shipments are pending, and managers must decide whether the main system is ready for ordinary stocking and feeding. Unlike the first days after the incident, the biological filter now contains a mature nitrifying population at its pre-outage density. Ammonia and nitrite have stayed below detection limits throughout two weeks of continuous monitoring. Staff also ran three supervised trials using the waste equivalent of the hatchery’s entire normal fish population and feed ration. In every trial, dissolved oxygen remained stable, the filter processed the added load with reserve capacity, and no water-quality rebound occurred. An independent aquatic laboratory confirmed the results and found no concealed pump or aeration defect. The biologists explicitly conclude that restoring the complete normal biomass and ration immediately cannot reproduce the ammonia accumulation, oxygen loss, or fish mortality associated with the outage.","scenario_title":"Hatchery Cleared After Full-Load Recovery Trials","vocabulary_separation_audit":"Retains the transfer case's aquaculture vocabulary and operational complexity while remaining clearly separated from the direct case's electrical-grid terminology."}],"experiment_id":"eoa_inverse_innovation_exp14_applicability_retrieval40_20260813","sample_id":"E14A037","schema_version":1}
