#   bats tests/bash
#
# The bash port has its own implementation of the exclude lists and config
# accessors, so it can drift from the PowerShell side independently. These
# mirror tests/ZHelpers.Tests.ps1 assertion-for-assertion where the two are
# meant to agree.
#
# A fixture config is injected through ZCONFIG (zhelpers.sh has always honored
# it), so no real zconfig.json is read.
