The spaced-token check used a 5-character token, which the new 16-character rule refuses on its own, so a validator that stopped checking spaces passed (reviewer mutation R06). It now uses a long token and checks the reason. Also pin F3 with no maintenance_enabled key: the default (off) holds and no no-price words show (reviewer mutation S04). Tests only.
