fix(web): unblock staging web image typecheck for inference probes

Docker next build rejected 909de8b8 because engine probe outcomes, reverse-verify source checks, and a nullable window scan failed TypeScript.

+## BUG-364 | staging quality gate 在 Mac Docker runner 上 npm ci 因 bind mount 被拒
+
+- 状态：investigating
+- 首次发现：2026-08-24
+- 最近更新：2026-08-24
+- 影响面：Gitea `backend-quality-gate.yml` 的 `validate`「Install dependencies」步骤、`publish`（因 `needs: validate` 被 skip）、staging 发布
+- 用户现象：向 `staging` 推送后质量门失败；测试步骤未执行。`publish` skipped。
+- 触发条件：job 被调度到 `jesse-mac-xiaoxin`（Docker Desktop 里的 `ubuntu:24.04` act_runner，label `xiaoxin:host`，使用宿主机 `docker.sock`）。Linux 宿主 runner `xiaoxin` 未接走该 job。已在 run `2051`（`29750d38`）和 `2052`（`909de8b8`）复现。
+- 根因：pip 安装成功。随后 `docker run --volume "$workdir:$workdir"` 跑 `npm ci` 时，workdir 是 runner 容器内的 `/root/.cache/act/<id>/hostexecutor`。该路径不在 Docker Desktop 的 Mac 文件共享里，daemon 返回 `mounts denied`，步骤以 exit 125 失败。不是 ledger 测试或 Python 依赖错误。最近一次完整成功是 run `2038`，跑在 Linux `xiaoxin` 上。
+- 修复：未修复。候选路径是让 Linux `xiaoxin` 重新在线并接 `runs-on: xiaoxin` 的 job，或不要用套了宿主机 docker.sock 的 Mac 容器跑这个 workflow。不要靠在 Docker Desktop 里共享 Linux 容器内部路径。
+- 验证：Gitea job `5135` 日志含 `Successfully installed` 全套 pip 包，随后 `docker: Error response from daemon: mounts denied` 与 `frontend npm ci failed with status 125`。job `5133`（run `2051`）同一错误。尚未在 Linux `xiaoxin` 上重跑 `909de8b8`。
+- 防复发：`runs-on: xiaoxin` 不得由无法给 job workdir 做 bind mount 的嵌套 Docker runner 抢占。质量门失败不得在未读 Install dependencies 日志时当成业务测试失败。

+## BUG-365 | staging web 镜像 next build 被推断类型检查挡住
+
+- 状态：resolved（本地修复，待提交与发布）
+- 首次发现：2026-08-24
+- 最近更新：2026-08-24
+- 影响面：`deploy/railway-web.Dockerfile` 的 `RUN npm run build`、`probeFromEngine`、`method-followup` 反推探针、`rectification-v9-tools` window scan
+- 用户现象：Linux `xiaoxin` 离线时在本机构建 `linux/amd64` web 镜像，`next build` 在 TypeScript 阶段失败，无法把 `909de8b8` 换上 staging。
+- 触发条件：当前 `staging` 头含推断 ledger，且走 Docker `next build`。staging push 的 validate 跳过 `npm run build`，因此测试可绿、镜像红。
+- 根因：`EngineProbeFields` 把 `expected_outcomes.answer_class` 收成 `AnswerClass`，与引擎探针的 `string` 相交后不能 `map(probeFromEngine)`。反推探针用字面量比较 `dasha_boundary`，在 `source` 收窄成 `age_band` 后被判无交集。`windowScanFromDecisionReceipt` 可为 `null`，调用方仍读 `.transitions`。
+- 修复：`probeFromEngine` 接受引擎探针并校验 `AnswerClass`。反推探针改走 `Set<string>`。window scan 用可选链，缺省空数组。
+- 验证：本机 `npx tsc --noEmit` 仅余测试夹具多余字段，已改为 `Object.assign`；Docker `next build` 待用新 SHA 重跑。
+- 防复发：staging push 的类型回归仍只在 publish Docker 暴露；本机/xiaoxin 镜像构建失败不得改 SHA 蒙混上线。
+- 相关记录：BUG-355、BUG-363、BUG-364
+- 复发自：BUG-355（validate 跳过 `next build`，publish 才暴露类型错误）
+- 修复版本：待发布
