// 2. 톤 키워드 비율 ≥ 70% 자동 측정
// 3. canonical URL 분리 (/matches/{id}/stat vs /observer)
// 4. fail 시 cron_pause INSERT (paused: true) + Slack 알림

// 5 시나리오:
// 시나리오 1: 정상 (PASS)
// 시나리오 2: 사실 차이 — STAT 'xG 1.2', OBSERVER 'xG 1.5' (FAIL)
// 시나리오 3: 톤 침범 — STAT body에 OBSERVER 키워드 80% (FAIL)
// 시나리오 4: canonical 충돌 — 두 article 같은 slug (FAIL)
// 시나리오 5: 환각 — match_facts에 없는 사실 (FAIL)
