  "venueScope": "All travel includes walking, bus and waiting; transport cost covers Alex's round trip. Activity cost is two equal-priced drinks. This exercise requires a continuous step-free route from bus stop to table and exit. Exit means leaving without depending on the counterpart's transport or permission. These are authored scenario requirements, not a diagnosis. Unknown hard observations fail review. Quiet/light values are authored 0-5 preference scores.",
