"""Offline and released-artifact entrypoint for the RillML conformance kit.

The offline mode never needs a key, network, registry, or runtime binary. It
checks deterministic distribution/protocol fixtures and negative selection
rules. The released mode delegates the real signed-pack, process-startup,
handshake, health, invoke, malformed-JSON, and clean-shutdown path to the
independent external-host smoke runner.
