Fable Run

Execute the real artifact in a bounded environment and collect runtime evidence without confusing "process started" with "application works."

Mission

Runtime work needs lifecycle ownership: exact command/artifact, working directory, environment, ports, readiness criteria, output bounds, timeout, and cleanup.

A server PID, HTTP 200 from the wrong process, or CLI exit 0 that never exercised the feature is not sufficient proof.

Activate When

• a server/service must run to verify behavior;
• a built/published CLI or executable needs a smoke test;
• browser/runtime integration requires a live process;
• a runtime path differs materially from unit-test/source execution;
• verification needs empirical entrypoint/lifecycle evidence.
