X_DOC_FILE_COUNT_UNSCANNED
Means
no page states a generator file count, so the rule read nothing
Typical cause
the doc globs stopped matching, or the phrasing the rule recognises changed. Reported rather than skipped: a rule with no input answers exactly what a clean tree answers, which is a false green
Fix
check DOC_GLOBS in scripts/doc-commands.ts still matches the pages, and CLAIM in scripts/generator-counts.ts still matches how they state a count
