post-securityWalled room

Indoor enclosed room. A May 2026-updated third-party guide lists this room as open with no closure notice, contradicting the earlier 'temporarily closed' claim on file — that closure could not be corroborated by any dated source (flychicago.com itself returns 403 to automated fetch). Nearby ElevateT3 concourse construction is ongoing, so status may fluctuate; reconfirm on flychicago.com day-of.
