Learn Kelvin

Short pages: the ones that get you running, and the ones that are easy to read the wrong way.

The local extension works without an account. Kelvin Code Cloud pages assume you are already in an organization: access is by named invitation.

ALPHA ARCHITECTURE

Artifact MCP and Live MCP

Artifact interprets a session that has already ended. Live exercises authority over a run. Keeping them separate keeps shared evidence away from control of a Mac.

Live MCP · live appCreate runs, enter rooms, and read sealed results for runs whose original audience includes you, using your identity, role, and lease.Dynamic interactive evidence · Artifact MCP — in preparationRead a sealed source allowed by your original audience or shared with you by name, explore its observed flow, and create authorized derivatives.
