Triage Worklist Prioritization

The inference engine emits a float32 confidence score of 0.5 (IEEE 754 binary32 0x3F000000) for a suspected ICH study. The site's configured ICH threshold is stored in the database as float64 value 0.5. The flag-assignment servic…

The agent upcasts float32 0.5 to float64 using lossless IEEE 754 widening (0x3F000000 → 0x3FE0000000000000), then applies a >= comparison. Because float32 0.5 maps exactly to float64 0.5, the comparison evaluates true and flag_assigned=true is written. The audit record stores: study_instance_uid, c…

An agent monitoring flag-assignment outcomes observes that 12 recent studies have float32 scores in the range [0.4999995, 0.5000005] and shows inconsistent flag outcomes, which the agent interprets as a float precision artifact. …

The agent does not apply the threshold change. It recognizes that threshold values carry clinical significance and may be changed only through an authorized process requiring sign-off from the clinical/medical director. The agent files an alert to the clinical performance engineer and medical direc…

The inference engine emits the largest float32 value strictly less than 0.5 (approximately 0.49999997 when interpreted as float64 after lossless upcast). The site ICH threshold is 0.5 stored as float64. The flag-assignment agent …

The agent upcasts the float32 value preserving its exact bit pattern, yielding a float64 value strictly less than 0.5. The >= comparison evaluates false and flag_assigned=false is written. No flag write is issued to either the Aidoc system or PACS. The study remains in the worklist at routine recei…
