Each of these would send a user down a path Vale does not support:
Core options placed under a glob header are not scoped to that glob — Vale
rejects them with E201, so the guidance to nest them produced a config that
will not load. The built-in `Vale` style is compiled in, but Vale still
requires StylesPath to exist on disk before it will run, so the "no StylesPath
needed" shortcut fails. The MDX guidance was inverted: under `[formats]
mdx = md` the mapping is what makes MDX lint at all, and it needs the mdx2vast
prerequisite that was never mentioned. And a spelling rule's `ignore` paths
resolve against StylesPath, not against the rule file's own directory, so the
documented relative paths silently matched nothing.
Covers invoking the vale CLI and interpreting its output — output
formats, severity filtering, exit-code handling, and false-positive
triage — for an already-configured project.
