  "description": "Benchmark part (CADGenBench generation sample 124) — 3-pivot rocker/bell-crank arm: O55/O40 big-end pivot at origin, truss to mid boss O20/O13 at (104.1,35.9), short link to forked clevis pair O20/O13 at (123.2,18.5) and (161.3,20.4), uniform 29mm thickness. Hollow I-beam arm cross-section approximated as solid strips; R31/R65/R0.5/R5 fillets and boss-height taper (40 vs 29) simplified/skipped for kernel+gate robustness. Safe to delete.",
