Offline, open, suggestion-only tool that reads each knowledge article's
good/bad .al samples + front-matter, proposes a routing 'signals:' block,
and flags declared-domain vs sample-content mismatches. Targets the
zero-signal domains (Style/Breaking Changes/Interfaces/Testing) and the
0-of-207 articles that declare no explicit signals today. Suggests only;
R24 + CI + human review remain the gate.
