+"""OKR 季度复盘提醒（缺口③：周期复盘节奏机制）
+
+用途：每季度第 2 个月中旬（2/5/8/11 月 15 日 09:00）提醒 owner 更新 objectives.progress / confidence。
+- 只读 objectives 表（status='active'），不改任何目标值（本单先只做"提醒"）
+- 通道复用：与 backend/scripts/daily_push.py 同一企微中继（RELAY_URL=http://127.0.0.1:8800/send，SOURCE=管理会计OS）
+  发送记录复用既有 notification_logs 表（channel=wecom）留存审计
+- 默认 dry-run（只打印，不推送）；--push 才真正发送
+
+用法：
+  cd /root/cma-management/backend && PYTHONPATH=. /usr/bin/python3 scripts/okr_review_reminder.py            # dry-run
+  cd /root/cma-management/backend && PYTHONPATH=. /usr/bin/python3 scripts/okr_review_reminder.py --push      # 推送
+  ... --entity-id 1   # 仅某企业
