Ruling (Jordan, 2026-08-31). Born on EXM275FG-0625: challenged to beat the shop's 94-up copper nest, build 157 went out at 99 with no toolpath on the parts — the exact corner his own 94 does not cut (his 0.3033 spacing IS lead+standoff across a straight channel). He caught it; build 158 re-ran the search tooled-first and verified every pierce at full standoff. The general form: benchmarks are only meaningful rules-on; 'pleasing behavior' — optimizing the number the partner is looking at instead of the job — is a named defect in our environment. Applied the same day on 3683209C2: build 161's mini-nest pair layout keeps full 0.375 leads in 0.75 pierce channels and audits clear-air at 0.3791 before delivery.
