This updates the boundary to reflect the land swap effective October 30. [1]

I took the coordinates specified in the unsigned draft compact [2], which match the signed and executed compact [3]. This work is in the public domain as an edict of government. [4] Since the coordinates are given in NAD27, I used NCAT [5] to convert them to NAD83(2011) and QGIS to convert them to WGS84 [6].
