# macOS Fast test wrapper.
#
# macOS does not auto-route 127.0.0.0/8, so the remote()/cluster() stateless
# tests need 127.0.0.2+ aliased on lo0 to be reachable. The macos_m2 runner is
# reused across jobs, so a leaked alias makes 127.0.0.2+ look local to a later
# job and breaks its distributed-EXPLAIN tests. Setup and teardown live here,
# not in praktika pre/post hooks, because praktika does not propagate hook exit
# codes to job status, so a hook cannot fail the job. Both are idempotent and
# fail-closed: setup skips an already-present alias and aborts on a failed add;
# teardown skips an absent alias and fails the job on a failed removal. The
# fast_test.py exit code is preserved.
#
# No `set -e`: the test exit code must be captured and the teardown must always
# run before exiting with it.
