Kev-Bio

"Every pixel is an option": medical ultrasound biometry rebuilt as System One decisions — clinical measurement questions generate queries for each caliper endpoint, matched against dense ultrasound features into spatial probability maps from which landmark coordinates and measurements fall out (MRE 22.50 px, measurement MAE 15.38 on the nine-view FU/GU Biometry 2026 set, beating specialist heads). No relation to kev above — the name is a collision; the pattern is decisions applied to spatial grounding. Code and models open.
