Integration

The runner is ./tests/run-integration.sh. Empty arguments run locally on macOS/Lima; --remote user@host cross-compiles and runs on Linux/Firecracker. Other supported arguments include --full, --profile LIST, and --name NAME.

Confirm the requested platform and prerequisites. A single host covers only one backend; never describe one backend as proving both. Run the suite with output redirected to a file, narrate progress during the long run, inspect the complete output, and report pass/fail per phase. Do not declare success unless the runner exits zero. Quote the failing phase, clean up the output file, and state any backend that was not run.
