Per Codex audit: only accept a polish when there's a gloss AND at least one example sentence that actually contains the word (case-insensitive). Examples that don't use the word are dropped; if none remain, fall back to the raw dictionary def/examples instead of shipping a gloss with empty/irrelevant usage.
