+# Track T：T2/T3 证据与 access-log 加强
+
+## 用户目标与授权
+
+- 用户目标：加强 trace T2/T3 证据路径与 access-log 设计闭环。
+- 交付终点：实现 + short 测试 + 本地提交；合入由 integrate worktree 完成。
+- 禁止：push（本任务）；扩大到无关模块。
+
+## 本批完成
+
+1. [x] `traceimpact` service/store 加强与单测
+2. [x] `access_log_middleware` + 单测
+3. [x] tip `684008e3` 已为本地 `dev` 祖先（merge 记录见主仓）
+
+## 验证
+
+| 范围 | 命令 | 判定 |
+|---|---|---|
+| middleware | `go test -short ./internal/server/ -run AccessLog` | 合入前 PASS（见 feat commit） |
+| traceimpact | `go test -short ./internal/traceimpact/` | 合入前 PASS |
+
+## 收口
+
+- `integration_state=merged`（本地 dev 已含 tip）；后续仅 cleanup。
