The pre-commit guard discards the sources refresh's stdout and stderr (>/dev/null 2>&1), so an older abcd that has the source verb but projects fewer patterns rewrites the generated block weaker and the commit prints nothing about it: a silent downgrade. A binary with no source verb prints 'refresh failed' on every commit, noise that teaches the committer to ignore the one line that matters. The guard should print the binary's one-line count, and one clear remedy line when the binary lacks the verb.

Grounds

• pursued: a refresh that wrote fewer patterns is visible on the commit that ran it; a commit whose refresh output is missing, or a verb-less binary reported as a failure, would show it wrong
