 - 剩余最值得继续补的点，已经缩成：
   - `ProvidersRepo.Upsert / PacksRepo.Upsert / ImportRunItemsRepo.Upsert` 更细的分支回读
   - `RedisStickyStore.open` 的剩余异常路径
+
+## 2026-05-30 已继续收口 sqlite Upsert 校验分支与 Redis open 异常路径
+
+**目标**：把上一轮仍然偏低的两块继续打透：
+
+- `internal/store/sqlite`
+  - `ProvidersRepo.Upsert / PacksRepo.Upsert / ImportRunItemsRepo.Upsert`
+- `internal/routing`
+  - `RedisStickyStore.open`
+
+**本次新增测试点**：
+
+- `internal/store/sqlite`
+  - `ProvidersRepo.Upsert`
+    - `pack_id / provider_id / display_name / base_url / platform` 校验错误
+  - `PacksRepo.Upsert`
+    - `pack_id / version / checksum` 校验错误
+  - `ImportRunItemsRepo.Upsert`
+    - `item_id / run_id / base_url / provider_id / api_key_fingerprint / current_stage / confirmation_status / access_status / matched_account_state / account_resolution` 校验错误
+- `internal/routing`
+  - `RedisStickyStore.open`
+    - `AUTH unexpected response`
+    - `AUTH read failure`
+    - `SELECT read failure`
+
+**验证结果**：
+
+- 定向测试：
+  - `go test ./internal/store/sqlite ./internal/routing -count=1` => `ok`
+- 定向覆盖率：
+  - `go test -coverprofile=/tmp/sqlite-upsert-followup.cover ./internal/store/sqlite` => `77.5%`
+  - `go test -coverprofile=/tmp/routing-open-followup.cover ./internal/routing` => `78.3%`
+- 热点函数回读：
+  - `internal/store/sqlite`
+    - `ProvidersRepo.Upsert = 72.0%`
+    - `PacksRepo.Upsert = 68.2%`
+    - `ImportRunItemsRepo.Upsert = 95.8%`
+  - `internal/routing`
+    - `RedisStickyStore.open = 82.8%`
+- 全量门禁：
+  - `gofmt -l .` => clean
+  - `go vet ./...` => `ok`
+  - `go test -cover ./internal/...` => `ok`
+  - `go test ./tests/integration/... -count=1` => `ok`
+  - `bash ./scripts/test/verify_quality_gates.sh` => `PASS`
+    - 真实门禁在 unrestricted 环境重跑确认
+
+**覆盖率变化**：
+
+- `internal/store/sqlite`
+  - 本轮前：`76.5%`
+  - 本轮后：`77.5%`
+- `internal/routing`
+  - 本轮前：`77.1%`
+  - 本轮后：`78.3%`
+
+**结论**：
+
+- `ImportRunItemsRepo.Upsert` 已基本打透，`open` 也不再是 routing 的主要薄点
+- 现在真正剩下的窄点已经进一步收缩为：
+  - `PacksRepo.Upsert` 的剩余更新分支
+  - `ProvidersRepo.Upsert` 的剩余更新分支
