CLI command
session-bus serve
Run the bus: the HTTP MCP server and its SQLite store.
Listens on BUS_HOST:BUS_PORT (default 127.0.0.1:47910) and stores messages at BUS_DB. The bind guard refuses any address that is not loopback or the host’s own tailnet address (exit 2).
It takes <BUS_DB>.lock before it opens the database or binds the port, so a second serve exits 3. GET /healthz returns {"ok":true,"schema":1}.
