Nine harnesses. One click.

Every install rewrites the config file the agent expects, keeps a checksummed backup, and hands you a rollback if the probe call fails. The dot next to each name shows the minimum tier that unlocks it.

The local /v1 surface.

An OpenAI-compatible listener, on your loopback. Any client that speaks the wire format talks to it as if it were the real thing. Streams pass through. Tool calls pass through. Costs stay yours.
