DIAG — narrowing a diagnosis

Raised by lemonfiber doctor --only, which runs one category of check, or one check by the name a finding gives it.

Code	Severity	Exit	What it means	What to do
DIAG-1	error	1	Nothing on this stack reports under the name you narrowed the run to. A check is named by the identifier its finding carries, and no finding here carries that one. Answering with an empty report would read as nothing being wrong.	Run the checks with lemonfiber doctor, and narrow to a name this stack reports.

What each severity and each exit means is on every error by code, beside every other family.
