Broker
The per-user background process that holds this host's capacity: the machine budget every run claims slots from, and the shared services runs keep warm. A run starts it on demand; broker: off in magus.yaml runs without one. Broker in full.
Daemon
The background process a person starts with magus server start. It serves MCP, the console, background jobs and the warm knowledge graph, and adopts nested magus calls into one pool. Daemon in full.
Pool
The concurrency pool: the shared set of slots that caps how many targets run in parallel on one machine. Its capacity defaults to MAGUS_CONCURRENCY, then 4 on GitHub-hosted runners, then min(NumCPU, 8); magus status and the dashboard report it live. Pool in full.
Health
The at-a-glance daemon state derived from the pool: healthy when the pool is reporting, degraded when it reports an error, down when there is no pool. The dashboard color-codes each state. Health in full.
Knowledge graph
The queryable graph of a workspace's spells, targets, docs, and code relationships; query it with magus query/explain/path. Knowledge graph in full.
