  "description": "Single-stage epicyclic gear reducer: 24T sun, four 18T planets, 60T internal ring gear (derived, conjugate-cut), planet carrier. Real involute tooth profiles, module 2, all four planets clocked in-phase. Ring fixed, sun in, carrier out = 3.5:1. Designed and built end-to-end by an AI agent through Orchard's agent tool surface.",
