Launchpad
Everything this member serves, read live from the member itself. Nothing here is hard-coded, so a capability this box lacks shows up as missing rather than as a link that fails.
Blockchain
The signed block chain held by this member.
Keychain
The consensus keychain: who is in the group, what quorum they require, and which generation is active.
Signature Lab
Hand a threshold-signed artifact and a keychain to a towel and get the chain's verdict. This is the same path a hosted model is given as a server-side tool.
Completions
Served by this member on its keychain port, driven over the IPC door to the engine. Add a server-side tool and the verdict is injected into the model's context before it answers.
Engine
The member does not start an engine; it reaches one over the IPC door.
Raw JSON
Any endpoint on this member, plus any towel method. This is the escape hatch — everything the other tabs do goes through these same routes.
