Daemon and Federation
The shared daemon is the single local owner of the knowledge engine’s writer lock. It binds MCP HTTP to loopback and authenticates agent bridges with a locally minted credential. This removes the failure mode where several agent-local servers compete for one embedded database writer.
agent CLI -> command-only bridge -> authenticated loopback daemon -> approved local sourcesWhat the daemon owns
- local writer coordination;
- authenticated loopback MCP serving;
- approved source retrieval and write-through integration;
- boot preflight that rejects unsafe registered sources.
What it does not own
- user model preference or a universal model ranking;
- raw terminal capture as memory;
- provider credentials in public output;
- a requirement that every clean local memory operation be online.
Federation is explicit. A developer can operate eBrain with local context, episodes, procedures, and workspaces before adding compatible sources. Source isolation remains the authoritative boundary. See privacy and public architecture decisions.
