Exit codes

Every command exits cleanly so you can gate on it from a shell or CI step.

Code	Meaning
0	Success, including non-gated warnings
1	Validation failure, or --fail-on-warnings tripped. The import was rolled back.
2	Unexpected error: auth, transport, or usage

The CI-style guard is the one-liner you expect:
