CI
An ordinary target you compose yourself with ctx.needs; magus does not hardcode its stages. It is the anchor magus affected ci keys off, and ci strips the rw charm. CI 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.
Session
An agent host's conversation, by the id the host delivers to its hooks. magus never mints one: a record with no session is unattributed, and the OS user it carries says whose account ran it. Session 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.
Lease
The grant a holder takes on a job: the write and read paths that job declared, enforced in the checkout that took it with magus job exec. A job is the piece of work; a lease is permission over it. Lease in full.
Advisor
One read-only check from the advice suite: it reads the changeset through magus and writes one titled section of findings. The same advisors run as a pull request comment in CI and inside magus diff --impact locally. Advisor in full.
