test(596-verify): section D names the record it read, and counts them

The object was whatever `find` reached first. A run that also builds a
dependency can leave more than one resolution.json under the work tree, and
traversal order is not a property of the record being tested. The probe builds
one project, so the count is the assertion and the file that was read is
printed beside the result.
