Disconnected geometries remain separate. Min/max heights are estimated terrain, not surveyed trail altitudes.",
  "facilityMethod": "Point-to-polyline nearest distance <=150m in local metre projection. Linear distance only, not a verified walking connection. Closed facility IDs joined exactly. Missing features do not establish absence or operation.",
  "waterGap": "Largest chainage interval between nearby, non-closed, mapped water stations including endpoints. No natural/campsite water treated as a drinking water station.",
  "closures": "Exact source TRAIL_ID join. Snapshot, not a live or exhaustive guarantee of closure/open status."
