-Verifies the vendored `mapd` routing binary authored by Jacob Pfeifer
-(github.com/pfeiferj/mapd), built from the gitlvb teal/mapd fork against
-teal/gomsgq. The only accepted binary is the checked-in one matching the pinned
-hash; nothing is ever downloaded at runtime. Jacob's stock release build embeds
-a 15-reader msgq header layout — on this fork (NUM_READERS=32) its registration
-writes land inside other processes' reader slots, so a wrong binary is
-quarantined rather than left where manager could start it.
