# The conformance harness asserts on the observed protocol exchange, not on the client's exit status,
# and echoes the client's output only when the exit status is non-zero. Several negative auth scenarios
# (e.g. `auth/resource-mismatch`, `auth/scope-retry-limit`) are expected to drive the client into
# a terminal failure: the SDK correctly refuses a mismatched resource or stops after the scope step-up
# retry limit. Report such an expected failure as a one-line reason and exit cleanly so the run stays
# free of noise, while letting any unexpected error (a real SDK bug) still raise with a full backtrace
# and a failing exit status.
