"""DefenseClaw E2E test runner.

Tests every CLI command, sidecar API endpoint, Splunk signal pipeline,
and gateway log verification. Designed to be re-run after any change.

Usage:
    python scripts/test-e2e-cli.py              # full run
    python scripts/test-e2e-cli.py --skip-api   # CLI only (no sidecar needed)
    python scripts/test-e2e-cli.py --skip-splunk  # skip Splunk verification
    python scripts/test-e2e-cli.py --verbose    # show command output

# gateway.log keeps the pretty human-readable sidecar output (stderr

# internal/gatewaylog.Writer and is the source of truth for
# dashboards + the TUI Verdicts tab. E2E probes should consult both
# when asserting behavior — legacy tests that only read gateway.log
# still work, but new assertions should prefer gateway.jsonl.
