Terms beginning with N describe where workloads run and how teams stay informed — namespaces, nodes, nightly builds and notifications. Each definition is plain-English and quotable.
A nightly build is a full compile, test and packaging run of the whole codebase triggered on a fixed schedule - typically once a day at night - independently of commits. It catches integration failures, slow tests and cross-platform breakage that shorter per-commit CI runs skip, giving teams a daily proof the mainline is still releasable.
