The name is a domain and is written as one. Script headers, the README, CHANGELOG and elevator pitch, their .txt twins, and the site page -- matching the same sweep in the private evo.scripts so the mirror does not drift. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

# touches. They report 0% and drag the total down, which is correct: the
|
|
# alternative measures only the files that already have tests and answers "how
|
|
# well covered is the covered code" - a question nobody is asking. The same
|
|
# mistake in vitest form made www look 91% covered when it was 17%.
|

#
|
|
# Pester counts *commands*, not statements. The collector labels it accordingly;
|
|
# the two are not interchangeable and averaging them would be nonsense.
