# Q136 CHECK -- the spark lane's word-frequency cell must grade the module and
# fixture beside it, and the repo gate's import-resolve leg must be green.
#
# rc 0 = every leg as expected; 1 = a graded fault; 2 = could not grade.
# The work is done by wizard-work/volt/q136_verify.py beside this file: the
# repo gate's leg, the cell run in place and copied out of the tree under an
# audit hook, the fixture's constants recomputed by an independent tokenizer,
# and two mutants -- a sabotaged sibling module the pre-repair binding reads
# green on, and the pre-repair bytes restored in a throwaway repository so the
# gate leg is shown to red.  The graded tree is only ever read.
