# CodeQL security scanning.
#
# README section 9.1 states the program's attack surface is zero. That is a
# claim derived from reading six lines, and a claim derived from reading is
# worth less than one derived from analysis. This workflow is the analysis.
#
# A finding here would be genuinely interesting and should be treated as
# such rather than dismissed.
