-    3. 触发 AI 应用 6 接口（P5 实现，本 SPEC 仅定义触发接口）：
-       - 调用 ai_analyze_note(note_id) → 返回 ai_score

-    5. 若 ai_score < 6：

+    2. 若 note_id 存在：重分类为 follow_up，task_status = 'completed'（回溯完成）
+    3. 若 note_id 不存在：task_status = 'active'（等待备注）

+    5. 冲突检查（T3）：
+       - 已有 completed → 跳过创建
+       - 已有 active → 旧任务标记 inactive + superseded 历史，创建新任务
+       - 不存在（或仅 inactive/abandoned）→ 正常创建
