    "reason": "Keep numbered, Korail and allowed light-rail lines, deduplicate exact directed patterns but retain branches/short turns and direction-specific Line 6 loop. Split at missing/construction stops. GTX-A discontinuity and >15 km hop remain explicit gate failures, never bridged. Base service selects full canonical branch patterns and excludes strict contained short turns and explicitly named 급행/express patterns; all originals remain for ALL_TAGGED queries. Expert seoul-1/2 confirms Jinjeop/Buramsan base termini, not the Hansung Univ. short turn."
