  "interpretation": "The capability/order guidance says plated-slot length should be at least twice its width. This exact library footprint has two 1.5:1 and two 1.875:1 slots. JLCPCB also describes drilling short plated slots, but that is not approval for this geometry. Generic KiCad DRC does not check this process ratio.",
  "resolution": "Obtain explicit JLCPCB DFM/process acceptance for the original shield slots and finished-hole tolerances, or qualify another USB connector/footprint and rerun routing, mechanical and fabrication checks. Do not silently enlarge/replace the imported slots or assume catalogue availability is fabrication approval.",
