Target
A named operation (build, test, ...) you invoke with magus run <target>; it may compose a spell's tool-native operations and depend on other targets. Target in full.
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.
Slot
One unit of the pool's capacity. A target acquires the slots it needs to run (most take one) and releases them when it finishes; the pool tracks capacity (total slots), running (acquired), and queued (blocked). Slot in full.
Queued
A target that wants a slot while the pool is full; it blocks first-in-first-out until a slot frees. The dashboard colors a sample with queued > 0 accordingly. Queued 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.
