Workspace
The magus root directory that owns a set of projects and shared config; the unit magus operates over. Workspace in full.
Project
A directory magus recognizes as a unit of work (it has a magusfile); the unit of caching, scheduling, and dependency tracking. Project in full.
Magusfile
The magusfile.buzz that declares a project's targets (as export funs) and binds its spells. Magusfile in full.
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.
Spell
A language/runtime adapter (e.g. go, md) that maps generic targets onto a toolchain's real commands. Spell in full.
Module
A magus stdlib namespace a magusfile imports for host capabilities: filesystem, exec, vcs, and more. Module in full.
Buzz
The language magusfiles are written in (the .buzz engine). Buzz 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.
Run
One target executing under one magus invocation, such as magus run test web or magus affected ci. A run keeps its captured output behind an output reference. Every magus run is a run whether or not any job asked for it; see Job for how the two relate. Run in full.
