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.
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.
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.
Insight
The reports magus derives over the graph and history (hotspots, affinity, ownership, trend, volatility, unreferenced). Insight in full.
Hotspot
An insight lens: edit frequency times complexity, the prime refactoring targets. The project view heat-colors the dependency graph by churn; --files ranks individual files. Hotspot in full.
Trend
An insight lens: the recent half of the window against the earlier half. A positive delta is a rising hotspot; a negative one is cooling. Trend in full.
