# Q133 CHECK -- the beam lane's two host-bound test cells must bind the module
# beside them, on a copy of the tree as well as in place.
#
# rc 0 = every leg as expected; 1 = a graded fault; 2 = could not grade.
# The work is done by wizard-work/volt/q133_verify.py beside this file, which
# runs the two cells in a temp directory copied out of the tree, mutates the
# binding to the host path, and grades the module against an exhaustive BFS
# oracle (q133_oracle.py).  The graded tree is only ever read.
