Its established sequence of automated screening, fixed incubation timing, and standard review rules performs reliably when specimens arrive promptly, have ordinary antibody profiles, and fall within familiar temperature and handling ranges. Recent validation work exposed a different pattern in less typical specimens. Samples with uncommon antibody combinations or modest transport delays produced inconclusive screens, unnecessary repeats, and occasional missed reactions. The change was not gradual: performance remained stable across the usual specimen range, then deteriorated abruptly after relatively small departures in timing, temperature, or profile complexity. Repeating the validation across instruments and shifts produced the same boundary. Although the laboratory appears dependable when judged by its normal caseload, its error rate rises sharply in the closely adjacent set of cases that do not match the assumptions embedded in its established processing sequence.","scenario_title":"Reliable Routine Screening, Abrupt Atypical-Specimen Failures","vocabulary_separation_audit":"This case uses clinical specimen, antibody-screening, incubation, and validation language; it does not use the archetype name, grounding name, supplied predicate wording, or an abstraction label."},{"alternative_route_blocks":[],"case_id":"E15A031__TRANSFER","case_type":"TRANSFER_POSITIVE","domain":"shellfish hatchery operations","intended_route_id":"B1","omitted_condition_id":null,"remedy_leakage_audit":"The statement describes hatchery performance under observed conditions without recommending equipment, staffing, training, process redesign, or any other intervention.","route_evidence":[{"condition_id":"b001_a15_dc_a2","intended_status":"SATISFIED","scenario_evidence":"The customary feeding and circulation schedule performs well during ordinary seawater conditions but fails when salinity and temperature combinations move beyond those conditions."},{"condition_id":"b001_a15_dc_a3","intended_status":"SATISFIED","scenario_evidence":"Production records show a small environmental departure followed by a sudden collapse in feeding and survival rather than a gentle decline."}],"scenario_text":"A coastal shellfish hatchery raises oyster larvae using a customary daily sequence for feeding, water exchange, aeration, and tank rotation. During the usual spring seawater conditions, the sequence produces uniform growth and predictable settlement across successive batches. Production records show a starkly different result when incoming water is slightly warmer while salinity is also below the seasonal norm. Within the ordinary combination of temperature and salinity, survival remains steady. Once either measure moves a short distance beyond that combination, feeding becomes uneven, oxygen readings oscillate, and larval survival drops within a day. Batches exposed to more extreme conditions do little worse than those just beyond the boundary, indicating a sudden collapse rather than a long, gradual decline. The same schedule therefore looks dependable throughout the conditions the hatchery usually encounters, yet becomes unreliable almost immediately when the surrounding water crosses a relatively tight environmental threshold.","scenario_title":"Oyster Batches Falter Beyond a Tight Water-Condition Threshold","vocabulary_separation_audit":"This case shifts to aquaculture and uses seawater, feeding, aeration, settlement, and larval-survival vocabulary, substantially separated from the clinical language of the direct case and from the supplied predicate wording."},{"alternative_route_blocks":[{"blocked_by_condition_id":"b001_a15_dc_a4","condition_set_id":"B2","how_blocked":"The scenario explicitly states that duties are shared across crews and fully documented, so performance does not depend on a few informal specialists or hidden workarounds."},{"blocked_by_condition_id":"b001_a15_dc_a5","condition_set_id":"B3","how_blocked":"The scenario explicitly provides unused tanks and scheduled staff time, contradicting a lack of operational headroom."},{"blocked_by_condition_id":"b001_a15_dc_a6","condition_set_id":"B4","how_blocked":"Earlier unusual tides were handled on schedule without disorder, delay, or stock loss, contradicting harmful or chaotic past adjustment."}],"case_id":"E15A031__NEAR_MISS","case_type":"ONE_LITERAL_NEAR_MISS","domain":"shellfish hatchery operations","intended_route_id":"B1","omitted_condition_id":"b001_a15_dc_a3","remedy_leakage_audit":"All potentially favorable features are stated as existing operational facts needed to exclude other routes; the statement contains no advice, proposed action, or solution description.","route_evidence":[{"condition_id":"b001_a15_dc_a2","intended_status":"SATISFIED","scenario_evidence":"The customary schedule remains strongest under ordinary conditions and becomes progressively less effective outside the hatchery's established operating range."},{"condition_id":"b001_a15_dc_a3","intended_status":"CONTRADICTED","scenario_evidence":"The scenario explicitly reports a broad tolerance range and a smooth, incremental decline with no cliff or tight threshold."}],"scenario_text":"A coastal shellfish hatchery raises oyster larvae using a customary sequence for feeding, water exchange, aeration, and tank rotation. The sequence gives its best growth and settlement results under ordinary spring seawater conditions. When temperature and salinity move beyond the range represented in the hatchery’s regular production records, feeding efficiency and survival do worsen. However, measurements from controlled batches show no tight boundary or sudden collapse. Results remain acceptable across a broad span of water conditions, then decline smoothly as departures grow; each additional temperature or salinity change produces only a small incremental loss. Duties are shared among several crews through complete written procedures, with no batch depending on a particular troubleshooter. The facility also has unused tanks and scheduled staff time available during the season. Two earlier atypical tides were handled on schedule without disorder, delayed settlement, or unusual stock loss. The present concern is therefore a gradual reduction in output far beyond customary conditions, not a sharp failure just outside a confined operating zone.","scenario_title":"Gradual Hatchery Losses Across Broadly Atypical Conditions","vocabulary_separation_audit":"The near miss retains the transfer case's aquaculture setting and technical difficulty while using explicit broad-range and gradual-decline evidence to negate only the frozen omitted condition; it avoids archetype and grounding terminology."}],"experiment_id":"eoa_inverse_innovation_exp15_route_aware_retrieval40_20260814","sample_id":"E15A031","schema_version":1}
