# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# This exercises the real Discover::Properties and Discover::Hooks worker
# code (not a reimplementation of their logic) so that the
# updated_device_hook_ignored_fields diffing is genuinely tested. Both
# plugins normally need a live SNMP connection and a live Postgres, neither
# of which is available to xt/ tests (there is no DB service in CI), so
# below we stub the few points where they touch SNMP/storage and let
# everything else run for real. Overrides are installed with
# "local *Package::sub = sub {...}" AFTER the target package is `use`d
# above, because installing them first would just get clobbered when
# Module::Load::load'ing the real plugin during the job compiles its own
# sub/import into that same glob slot.
