结构化事件(可映射为 serve 日志事件 / onStoreError):

• store.segment_sealed:收到封段通知,已入队(热层事实);
• store.segment_committed:段 put 成功且冷清单 CAS 已提交(冷层事实;可逐出);
• store.commit_failed:一次上传 / 提交失败(gaveUp = 重试预算耗尽或 permanent / precondition_failed 放弃;此后该段留在热盘、积压可见);
• store.hot_full:热盘触顶(ready → false);store.hot_recovered:回落;
• store.evicted:已提交段的本地文件被逐出;
• store.orphan_gc:孤儿对象清理(段已 put、清单未引用)。
