Examples 1-3: clean global sweep (single, 10 samples, JSON). Examples 4-8: one failure type each (DNS, refused, timeout, HTTP, TLS). Example 9: full matrix, all 5 failure types in one run. Example 10: quick smoke test (-n 1, JSON, --timeout 2s, all types). Includes runtime estimates and jq filter snippets. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
