- 流式放行前的上游错误判定加廉价子串预过滤（"error" / response.failed）： 长思考阶段几十上百条事件不再逐条 json.Unmarshal。 - usage_logs 去掉 idx_channel_created：没有任何查询按 channel_id 过滤该表 （渠道统计走 created_at 时间窗后在内存分组），复合索引只是每行一次多余的 B-tree 插入；schema v9 迁移里显式 DROP 旧库索引。至此该表只剩 (user_id, created_at)、created_at 两个真被用到的索引。 - 新增可选保留期（OT_USAGE_RETENTION_DAYS，默认 0=永久保留）：每天分批 （2000 行/批、批间 50ms）清理过期 usage_logs，避免长期运行后时间窗查询 与备份随表增长变慢；余额流水 balance_logs 不在清理范围。 参数复测（记账稳态吞吐，3 次取中位）： - batch 64（当前）30.2k rows/s；batch 128 19.0k、batch 256 14.3k（更差，保持 64） - wal_autocheckpoint(4000)、cache_size(-64MB) 与当前配置无差别，不引入 验证：go vet、go test ./...、-race（usage/proxy/store）全绿；新增保留期三项测试 （只删明细不动流水、未开启不动数据、跨分批删完）。
