fix: rebase 合入修复（#215 已合并 + 执行器文案 + server 重导出）

- cloud/server.py：重导出 handler_support._chv_vm_dead_from_row，
  沿用 main 的 split 重导出约定（test_chv_arch_maint_fe 从
  cloud.server 导入该名）。
- cloud/tests/test_coverage85_server2.py：执行器非法值文案期望
  跟随分支行为（valid 列表已含 cloud-hypervisor，main 新增
  的该用例原先按旧文案断言）。
- cloud/chv/compat215.py + test_chv_arch_maint_fe.py：#215
  （facc2a2）已合入 main，四模块已存在，替换清单本身未动；
  钉住项由“模块不存在”翻为“模块已存在”，tmpfs_isolated
  扫描白名单加 canonical 定义 cloud/sandbox_policy.py。
  R1/R2 替换本身未做（属合并后工作）：语义已核对，
  gates.resolve_inside 与本地版逐行一致，
  sandbox_policy.tmpfs_isolated 对 cloud-hypervisor
  同样返回 False，未触发 R2 的停手条件。

+# Cloud Hypervisor 客机镜像（chv-guest）——内容清单与版本化构建说明
+
+> 本目录有清单与真实构建步骤（build.sh，补缺口轨已实做），
+> 但镜像本身不在本轨内实际构建发布。原因写在前面，不藏着：
+> 当前没有带 /dev/kvm 的宿主可以构建并实测 VM 镜像（生产
+> 主机是 CVM、无嵌套虚拟化；本 VM 容器内同样无 /dev/kvm）。
+> 构建与实测见 `docs/chv-production-readiness.md` 的“需镜像
+> 构建 / 需 KVM 宿主实测”项，绝不在本轨声称镜像已建成、
+> 已发布、已跑通。
+
+## 1. 镜像定位
+
+- 基础：Ubuntu Minimal 24.04 官方云镜像（轻量口径，2026-11-06
+  用户定：停掉 5.5G 全量版，不再对齐 Manus，不做三面板/
+  多租户/生产级全套；只装 codex + Python + SSH + cloud-init
+  + 薄客机 agent + git + gt + 最小中文字体）。
+- 载体：Cloud Hypervisor 直接内核启动（vmlinux）+ raw 磁盘
+  镜像，执行器用 `CHV_KERNEL` / `CHV_ROOTFS` 指向它们。
+- 客内 host.py 位置：`/app/host.py`（与 Docker 的 `/app:ro`
+  同款约定，只是载体从容器只读挂载换成 VM 镜像内置代码；
+  代码版本 = 构建时仓库 commit，见 §3 版本化）。
+- 绝不进镜像的东西：任何模型 key、系统 key、用户账号数据、
+  生产凭证。模型 key 由客机 cloud-init 预置的运行环境变量名
+  注入（与 Docker 的 `-e <名>` 同款惯例），不写进镜像层。
+
+## 2. 内容清单（轻量口径，2026-11-06 用户定）
+
+| 类别 | 内容 | 来源/版本口径 |
+| --- | --- | --- |
+| 语言与工具链 | Python 3.12、git、curl、ca-certificates、xz-utils、fontconfig、openssh-client（Node.js 不装：Playwright 驱动是 Python playwright，见 PLAYWRIGHT=1 分支；任务镜像 Dockerfile 里也没有 Node.js，本清单不虚构它） | 构建时钉小版本并记入构建日志；apt 用 --no-install-recommends（B-21：默认装 Recommends 会连带拉入 gcc 全套工具链顶满根分区） |
+| 文档/图片工具 | 已裁剪：pandoc、poppler-utils、latexmk、texlive-latex-base、python-docx、openpyxl、python-pptx、PyMuPDF、Pillow 不在轻量镜像内 | 全量版曾照抄 `cloud/docker/Dockerfile` 的 apt/pip 清单，轻量版按用户决定砍掉 |
+| agent 引擎 | codex、codex-code-mode-host、codex-resources/bwrap（成套，约 367M，缺 sibling 直接构建失败） | codex 0.164.0-alpha.9（与生产任务镜像一致）；`CODEX_BIN_DIR` 由构建方提供，bin/ 不进仓库 |
+| 浏览器 | Playwright + chromium-headless-shell（默认装，不要完整 Chromium） | Python playwright 装当时的 headless-shell，版本以 ms-playwright 缓存目录名记入 BUILDINFO.versions.chromium；浏览器在系统路径 /usr/local/share/ms-playwright（B-22：virt-customize 里 HOME=/，默认缓存会落到根目录 /.cache），agent 运行时须设 PLAYWRIGHT_BROWSERS_PATH 指向它；单独钉死见 §3：CHROMIUM_HEADLESS_SHELL_REV 设为纯数字修订号即钉死，未设时只记录、不强制 |
+| 客机基础 | openssh-server（SSH 通道用）、cloud-init（qemu-guest-agent 已裁剪，CHV 不用它） | sshd 只允许 key 登录，禁止密码登录——build.sh 写入 /etc/ssh/sshd_config.d/99-chv.conf 并经 sshd -t + grep 断言（feat-chv-secfix，M8，此前只是文档声称） |
+| Gitea 同步 | gt 1.0.0（官方 install.sh + SHA256 校验）、chv-sync（启动时 clone、显式 pull/push 的同步脚本） | 凭证走 seed 盘 /etc/chv/guest-env（0600）投递，不进镜像；见 §7 |
+| 任务代码 | 仅 `/app/host.py` 一个文件（host.py 只用标准库，不依赖 cloud/；旧版把整个 cloud/ 拷进 /app/，客内可读全套 server/worker 代码，M4 收尾已收紧为最小集） | 版本见 §3（repo_commit），不挂载宿主代码目录（VM 与宿主无共享路径） |
+
+中文 LaTeX 说明：与 Docker 镜像同款口径——xelatex + CJK
+字体会再增数百 MB，本清单不默认包含；需要时单独一版镜像，
+不在本轨悄悄加。字体只留最小的 fonts-wqy-microhei（中文能
+看），不要全套 fonts-noto-cjk。
+
+## 3. 版本化
+
+镜像 tag 格式（构建时三项缺一即失败，不生成无版本镜像）：
+
+```
+chv-guest-<ubuntu 版本>-<codex 版本>-<仓库 commit 短 hash>
+```
+
+例如（示例格式，非已建成）：`chv-guest-24.04-0.164.0-alpha.9-aebc623`。
+
+构建产物清单（构建方必须输出，执行器用它做 preflight 之外的
+版本核对，v1 执行器暂不校验 tag，见就绪清单）：
+
+- `vmlinux`（与 Ubuntu 云镜像配套的内核）
+- `disk.raw`（根文件系统镜像）
+- `BUILDINFO.json`：`{ubuntu, codex_version, repo_commit, built_at,
+  contents: [清单逐项名]}`——contents 只有名字列表；逐项版本
+  在 `versions` 里（B-02：dpkg + pip freeze 从客机读回，
+  chromium 以 ms-playwright 缓存目录名记，gt 以 gt_version 记），
+  `generate_lockfile.py` / `check_lockfile.py` 以它为唯一来源。
+  Chromium 单独钉死：构建时设 CHROMIUM_HEADLESS_SHELL_REV
+  为纯数字修订号（如 1248），buildinfo.py 校验读回的缓存
+  目录名须恰好是 `chromium_headless_shell-<rev>`，否则构建
+  失败，BUILDINFO.chromium_pinned_rev 记该值；未设时记 null、
+  只记录不强制，构建输出明说“未钉死”。真实 lockfile 产出
+  须等 V-9 真机构建（本机无 /dev/kvm，版本号绝不编造）。
+
+## 4. 构建脚本（补缺口轨：已从骨架改成真实步骤）
+
+见 `build.sh`：参数校验 → 下载 Ubuntu Minimal 云镜像（SHA256
+必填）→ qemu-img 转 raw（轻量版不扩盘，底座根分区 2.4G 够用；
+全量版 B-16 的 +12G 扩盘已删除）→ virt-customize 装 §2 清单、
+拷入 codex 成套二进制与 host.py（仅此一个文件，不拷 cloud/）
+到 /app、装 gt 1.0.0、拷入
+chv-sync 并写 cloud-init 启动钩子、写 host key 不重生成配置 →
+virt-get-kernel 取内核 → 生成并校验 BUILDINFO.json。
+`./build.sh --dry-run out/` 只打印命令、不执行、不要求
+KVM；全量模式在无 /dev/kvm 的机器上第一步就明确退出
+（`CHV_GUEST_BUILD needs a KVM host`），绝不假装构建成功。
+全量版曾在 WSL KVM 宿主（ajpkmq6i）上跑过四轮真机构建，
+轻量版沿用同一宿主与流程，构建记录见 `~/workspace/chv-prod-audit/`。
+
+## 5. Host key 首启注入硬性要求（补缺口轨新增）
+
+执行器的 per-VM 预置方案（见 `cloud/chv/hostkeys.py`）能
+跑通的前提是客机镜像必须满足以下全部，否则预置在真机
+上跑不通，执行器会 fail-fast，不回落成弱方案：
+- 装 cloud-init 且支持 NoCloud seed（seed 磁盘（CIDATA ISO，feat-chv-fix 起挂进 VmConfig
+  第二块只读盘）由执行器在 VM 启动前生成，含 meta-data 与 user-data）；
+- 首启时先应用 seed 再启动 sshd，seed 里的 user-data
+  把该 VM 的 host key 对写进 /etc/ssh/（write_files，
+  0600）；seed 里绝不能带 `runcmd:`——user-data 的
+  runcmd 会整体替换镜像 `/etc/cloud/cloud.cfg.d/` 里
+  的 runcmd（cloud-init 不跨配置类型合并），旧版 seed
+  的 restart ssh 两行就这样顶掉了 `99-chv-sync.cfg`
+  的 `chv-sync boot` 钩子（sync-test 首轮实测）；sshd
+  重启由镜像自己的 runcmd（`99-chv-sync.cfg`，cloud-final
+  阶段）做，见 `cloud/chv/hostkeys.py` 根因禁令；
+- 镜像里已钉死 `ssh_deletekeys: false`（build.sh 已写），首启
+  不得无条件重新生成 host key——重生成会使预置的 known_hosts
+  立即失效，SSH 钉死直接拒绝，这是设计，不是 bug；无预置 key
+  时首启 bootcmd 只在缺 key 时 `ssh-keygen -A` 生成（B-23：
+  曾写 `ssh_genkeytypes: []` 彻底关掉首启生成，客机 sshd 起
+  不来，已删，绝不再写）；
+- sshd 只允许 key 登录，禁止密码登录（build.sh 写入
+  /etc/ssh/sshd_config.d/99-chv.conf：PasswordAuthentication no、
+  PermitRootLogin prohibit-password、ChallengeResponseAuthentication no、
+  KbdInteractiveAuthentication no、PubkeyAuthentication yes，并经
+  sshd -t + grep 断言；feat-chv-secfix，M8）；
+- seed 磁盘是 per-VM 敏感物，执行器在 VM 关闭/
+  回收时删除，镜像构建方不得把任何一把 host key 固化
+  进镜像（所有 VM 同 key 是安全事故）。
+
+## 6. 与执行器的对接
+
+- 执行器 preflight 只校验内核/镜像文件存在且可读，不校验镜像
+  内容版本——内容版本核对（BUILDINFO）是镜像发布流程的责任，
+  在就绪清单里标为“需镜像构建”项，不在本轨假装已做。
+- 每任务磁盘：执行器 copy 模式下把 `disk.raw` 复制为每任务
+  磁盘，任务之间文件系统独立；reuse 模式仅单租户实验，preflight 拦截（须同时设 CHV_REUSE_SINGLE_TENANT_EXPERIMENT=1 并审计放行，feat-chv-fix）。
+- 快照基准：`CHV_SNAPSHOT_URL` 指向的快照必须由本镜像的干净
+  启动状态制成（pause 后 snapshot），预热池用它做干净 VM 来源。
+
+## 7. Gitea 双向同步（用户工作区口径，2026-11-06 追加）
+
+主角是用户，不是 agent：用户在 Gitea 上的仓库在 VM 启动时
+clone 到 `~/workspace`，用完再同步回 Gitea；VM 是用户的工作
+区，Gitea 是权威远端。同步口径沿用 Git Workspace Platform
+已定的规则：分叉或冲突时失败关闭，不强制覆盖、不自动
+rebase、不静默丢提交。
+
+- 凭证：seed 盘投递 `/etc/chv/guest-env`（0600，root 所有），
+  含 `GITEA_URL` / `GITEA_USER` / `GITEA_TOKEN` / `SYNC_REPO`
+  / 可选 `SYNC_BRANCH` / 可选 `GITEA_EMAIL`。token 绝不进镜像、
+  代码、日志；`chv-sync boot`（root，cloud-init runcmd 调）把
+  token 写进 `/home/chv/.git-credentials`（0600，git credential
+  store 标准机制），再以 chv 身份 clone；`pull` / `push` /
+  `status` 以 chv 身份跑，只用已落盘的 credential，不再读
+  guest-env。无 guest-env 的启动静默不同步，VM 照常用。
+- 行为：`boot` 只在未 clone 时 clone，已 clone 则静默退出，
+  不自动 pull（避免重启时覆盖进行中的工作）；`pull` 要求
+  工作树干净且只接受 fast-forward；`push` 无 upstream 时
+  `push -u origin HEAD`，否则普通 push，非 fast-forward 即
+  失败，绝不 `--force`。
+- gt 1.0.0 随镜像装好（官方 install.sh + SHA256 校验），登录
+  不 baked：运行时用 `GITEA_TOKEN` + `GITEA_CLI_HOST` 环境变量
+  即可用（`gt repo list` 等），或在 VM 里 `gt auth login`。
+- 验收（用户视角）：VM 启动后仓在 `~/workspace` 且是最新
+  HEAD；VM 内改文件 commit push 后 Gitea 网页可见该提交；
+  Gitea 上改一次后 VM 内 pull 能同步回来。双向都通才算集成通。
+- 集成（2026-11-07，第二轮第一棒）：执行器生成 seed 时自动写
+  guest-env 已做（`cloud/chv/gitea_sync.py` + `wake_vm`）：
+  GITEA_TOKEN 进密钥集（只进 seed，绝不进 argv），其余 5 键
+  也随 seed 进 guest-env；来源是宿主 `CHV_GITEA_*` 环境变量
+  或任务 `gitea_sync` dict；必填 4 键缺失时起 VMM 前
+  fail-closed（`gitea_sync_incomplete`），无同步变量时静默
+  不同步。客机用户与静态网络由 seed 附加项供给：
+  `CHV_SEED_USER_DATA_EXTRA_FILE`（含 `users:` 块的文件）与
+  `CHV_SEED_NETWORK_CONFIG_FILE`（NoCloud network-config），
+  路径配了但文件读不出时 wake 前 fail-closed
+  （`seed_extra_missing`）；附加 user-data 里禁 `runcmd:`。
+  专用 token 与测试仓名须用户给，本轨不自编 token、不动
+  生产 Gitea 配置。

+"""chv-cell：客机内 codex 运行时单元（Hatch 式）启动器。
+
+对齐 Muse P2（见 docs/chv-muse-p2-gap.md）：codex 跑在单元内，不再
+直接跑在客机用户态。单元是单命令沙箱——单元即沙箱，单元内 codex
+用 danger-full-access，不再套 bwrap（bwrap 的 --proc 挂载在嵌套命名
+空间里走不通，见 AGENTS.md 内层 proc 定位）。
+
+关键映射（与 Muse“单元 root 映射为 host 侧非特权用户”同款）：
+  单元内 uid 0 → 客机侧 chv（uid 1000）。
+  效果：workspace / ~/.codex（chv 所有）单元内仍可写；host-root 0600
+  文件（如 /etc/chv/guest-env）在单元内显示为 overflow uid、不可读；
+  再加挂载遮蔽作纵深防御。
+
+网络：veth。宿主侧 ve-chv-cell（10.200.0.1/24），单元侧
+host0（10.200.0.2/24，默认路由经 10.200.0.1），客机侧 NAT 出站
+（MASQUERADE 走客机默认路由的上行口，动态发现）。单元内配网经
+nsenter 进单元 init 的 netns 做。veth 建不起来即大声失败，不静默
+回落共享网络；CHV_CELL_NETWORK=shared 是显式调试逃生口，须显式
+设置并打日志，绝不默认。
+
+环境透传：本脚本只转发白名单变量（模型网关与代理变量）。GITEA_TOKEN
+等凭证变量不在白名单里，绝不进单元。
+
+实现（2026-11-07 阶段 2 改写，见末尾“后端说明”）：
+  不再调 systemd-nspawn，改用纯标准库 userns 启动器：root 起进程，
+  子进程自己 unshare 用户命名空间并写 uid_map/gid_map（内 0 →
+  外 chv 1000），再进 mount/pid/net 命名空间、挂 fresh /proc、
+  遮蔽敏感路径、设 no_new_privileges + seccomp（禁 io_uring 三件套）
+  + 丢 capability，最后 exec payload。父进程在外配 veth/NAT、等
+  payload 退出码、清 NAT。只用标准库，无新依赖、无新包、无 sysctl
+  改动。
+
+用法（客机侧 root 运行，执行器经 SSH 调）：
+  chv-cell run [--network veth|shared] -- <cmd...>
+      # 例：chv-cell run -- python3 /app/host.py --state
+      #   /home/chv/.codex/host-state.json --codex-home /home/chv/.codex
+      #   --sandbox danger-full-access dispatch --name t --task ...
+  chv-cell argv [--network veth|shared] -- <cmd...>
+      # 只打印单元规约（JSON：映射、挂载、网络、环境名），不启动。
+      # 环境值只印 <redacted>，绝不印真值。
+  chv-cell network-commands [--uplink IFACE] [--cell-pid PID]
+      # 只打印配网命令表（JSON），不执行。
+单元启动失败、配网失败一律非零退出，不静默降级。
+
+后端说明——为什么不用 nspawn（2026-11-07 真机实测，systemd 255.4）：
+  nspawn 的 --directory=/ 在本版 systemd 上走不通，修一个冒一个：
+  ① 裸 --no-new-privileges 被当成要值、吞掉下一个参数
+     （Failed to parse --no-new-privileges= argument）；
+  ② --directory=/ 被根目录检查挡住，须加 --volatile；
+  ③ --volatile=state 又要 /run/host/os-release 挂载点（须预建）
+     与空 /dev（--tmpfs=/dev 不生效，staging 根的 /dev 已填充）。
+  结论：nspawn-on-/ 在此 systemd 上不可行，cell 从未 live 跑通过
+  （阶段 1 只测了参数表纯函数，未 live 起过单元）。bwrap 作 chv
+  也被 Ubuntu 24.04 的 AppArmor userns 门（
+  apparmor_restrict_unprivileged_userns=1）挡住，newuidmap 客机
+  未装；本启动器由 root 写映射，不碰这两处限制。

+"""chv-daemon：客机运行时 daemon（阶段 2 三分之一）。
+
+职责（只做这三件，不碰任务执行与同步）：
+  1. 生命周期/心跳：每 10 秒写 /run/chv/heartbeat.json（atomic），
+     含 pid、启动时间、seq、uptime、loadavg、内存、workspace
+     余量、execd 任务数、sync 最近状态摘要。seq 跨重启连续
+     （启动时读旧文件续号），宿主侧据此判断“心跳丢了还是
+     daemon 重启了”。
+  2. 资源上报：同上，心跳文件即上报载体（宿主经 SSH 读文件，
+     不另开通道；控制通道仍是 SSH，见 executor.py 定稿）。
+  3. 快照配合：Unix socket /run/chv/daemon.sock，op
+     prepare-snapshot——问 execd 是否有运行中任务；有则
+     拒绝（{ok:false, reason:task-running}），无则写
+     /run/chv/snapshot-ready.json 标记并返回 ok；execd
+     联系不上时同样拒绝（fail-closed，不写标记）。
+     宿主侧快照流程暂未调它（阶段 2 不改 executor 快照流），
+     接口先行、供宿主侧后续接线与本阶段 live 演练。
+
+与既有分工的映射（不要第二套 agent）：
+  - host.py 仍是唯一的任务/ codex 执行引擎（CLI，经 SSH 或
+    execd 的 codex op 调）；daemon 从不跑 host.py。
+  - chv-broker/chv-browser 仍是单元内外 IPC 与浏览器子代理，
+    daemon 不碰它们的 socket。
+  - sync 仍是 chv-sync.sh + chv-syncd 常驻循环，daemon 只读
+    sync-status.json 作摘要，不调 git。
+
+只用标准库。以 root 运行（读 /proc 与各服务状态文件无权限
+问题；socket 0600 root:root，只接受本机 root 客户）。

+#
+# 主角是用户，不是 agent：用户在 Gitea 上的仓库在 VM 启动时
+# clone 到 ~/workspace，用完再同步回 Gitea；VM 是用户的工作区，
+# Gitea 是权威远端。同步口径沿用 Git Workspace Platform 已定
+# 的规则：分叉或冲突时失败关闭，不强制覆盖、不自动 rebase、
+# 不静默丢提交。
+#
+# 凭证绝不进镜像。启动时由 seed 盘投递 /etc/chv/guest-env
+# （0600，root 所有），格式（KEY=VALUE，每行一项）：
+#   GITEA_URL=https://gitea.tose.top
+#   GITEA_USER=<Gitea 用户名>
+#   GITEA_TOKEN=<专用 API token，仅此次测试/此次 VM 有效>
+#   SYNC_REPO=<owner/repo>
+#   SYNC_BRANCH=<可选，默认分支>
+#   GITEA_EMAIL=<可选，commit 身份邮箱；不给则留镜像占位>
+# boot（root，cloud-init runcmd 调）读 guest-env，把 token 写进
+# /home/chv/.git-credentials（0600，chv 所有，git credential
+# store 标准机制），再以 chv 身份 clone 到 ~/workspace/<仓名>。
+# pull/push/status 以 chv 身份跑，只用已落盘的 credential，不
+# 再读 guest-env；token 不会出现在 git remote URL 或镜像里。
+#
+# 用法：
+#   chv-sync boot              # 启动时 clone（已 clone 则静默退出，不自动 pull）
+#   chv-sync pull [仓目录]     # 脏树拒绝；只接受 fast-forward，分叉即失败

+接受 ping/status/sync-now。
+
+同步规则一条不改（与 chv-sync.sh 同款，复用它不重写 git 逻辑）：
+  - Gitea https://gitea.tose.top 是权威远端；启动 clone 选定仓
+    最新 HEAD（仍由 cloud-init runcmd 的 chv-sync boot 做；
+    syncd 只在仓已 clone 的前提下循环，仓不存在记 needs-boot
+    不擅自 clone——boot 须 root 写 credential，syncd 以 chv
+    身份跑，无权也不该碰）。
+  - 每轮先 pull --ff-only 再 push；pull 分叉即停住、跳过 push，
+    状态记 error、绝不 --force、不自动 rebase、不覆盖任何一方。
+  - 工作树脏时 pull 拒绝，同样记 error 等下一轮，不丢改动。
+  - push 只推已提交的提交；未提交改动不参与同步。
+  - token 只走 /home/chv/.git-credentials（0600），syncd
+    自身不读 guest-env、不打印、不记入状态文件与日志。
+
+以 chv 身份运行。默认每 300 秒一轮（CHV_SYNC_INTERVAL，

+版本来源映射（绝不编造版本号，查不到的进 unresolved）：

+"""Declarative agent definitions (harness alignment, v1).
+
+Zero third-party dependencies; standard library only.
+
+A definition is a versioned JSON document that bundles the fields a
+task already understands -- model, effort, approval, executor, plan --
+plus a human-written instruction block and a list of required skills.
+It is the Foundry-style "agent defined declaratively, harness runs
+the loop" idea, cut down to what this codebase can actually honour
+today, with every boundary written down instead of implied:
+
+* Resolution happens at task creation (``POST /tasks`` with an inline
+  ``agent`` object). Per field, an explicit body field wins over the
+  definition; a field absent from both stays NULL and follows the
+  existing worker-default chain. A definition that sets ``model``
+  therefore makes the task explicit for rule routing v0, and a
+  definition that leaves ``model`` empty leaves routing to the worker.
+* Instructions reach the model only as a marked header prepended to
+  the stored prompt (``[Agent: <name>]``), because the dispatch path
+  (``cloud/sandbox.py`` -> ``host.py dispatch``) has no
+  developerInstructions channel today. This is NOT claimed to be
+  ``developerInstructions``: it is visible in the stored prompt, in
+  the creation response, and in every later prompt read. Instructions
+  are rejected with goal tasks and coordinator tasks, where the
+  prompt is a goal or is never run as a model turn, so the header
+  cannot silently pollute a goal text or a coordinator parent.
+* Skills are validated against the ``cloud/skills/`` pack at parse
+  time (an unknown skill is a 400, never a silent drop). Seeding
+  itself stays worker-global (``--seed-skills`` seeds the whole pack
+  into the tenant codex-home); v1 does NOT claim per-agent seeding.
+  When seeding is off, a listed skill is recorded in the creation
+  response but is not guaranteed present at run time -- that is the
+  documented v1 boundary, not a bug to be discovered later.
+* Routing policy is deliberately NOT part of a definition in v1:
+  routing stays a worker-global policy (see ``cloud/models.py``).
+  Putting a routing object inside a definition would either be
+  silently dropped (a lie) or need a per-task policy column that does
+  not exist. A definition that contains ``routing`` / ``routing_policy``
+  is rejected, so a typo or a v2 idea cannot masquerade as v1 behaviour.
+* Unknown top-level or defaults keys are rejected for the same
+  reason: a declarative file must fail on typos, not silently ignore
+  them.
+
+v2 (this file, plus server/worker/sandbox/host changes) closes the
+three v1 boundaries that were explicitly left open:
+
+* Registry: definitions can live as files under repo-root ``agents/``
+  (``default_agents_dir()``) and be referenced by name
+  (``agent_name``) instead of only inline. The server never loads a
+  definition from a caller-supplied path; it only loads
+  ``<name>.json`` under the registry dir, with the traversal guard
+  in ``load_agent_definition``.
+* Persistence: ``tasks`` gains ``agent_name`` / ``agent_version`` /
+  ``agent_instructions`` columns (see ``migrate_tasks_table``), so
+  ``GET /tasks`` shows the definition identity and instructions, and
+  the worker no longer has to reconstruct them from a prompt header.
+* Real channel: for local/docker executors, instructions travel as
+  ``--developer-instructions`` on the host.py top-level command,
+  through ``sandbox`` into ``host.py dispatch`` ->
+  ``create_thread(developerInstructions=...)``. The stored prompt
+  stays clean. For the generic cloud executor, which has no such
+  channel, the worker falls back to the v1 marked header in the
+  in-memory dispatch prompt only (DB prompt stays clean) -- that
+  fallback is the documented cloud boundary, not a claim that the
+  cloud runner honours developerInstructions. Goal and coordinator
+  tasks still reject instructions in v2: the goal loop and the
+  coordinator parent do not pass instructions through, and silently
+  dropping them there would be worse than rejecting them.
+
+v3 (tools, this file plus server/worker changes) adds a ``tools``
+field, but deliberately as REQUIRED tools, not an allowlist:
+
+* A definition may declare ``tools`` from the MCP servers this
+  codebase actually seeds: ``websearch``, ``imagegen``,
+  ``playwright``. An unknown tool is a 400, never a silent drop.
+* The worker does NOT claim to block other tools. Blocking would
+  need a tool allowlist in ``create_thread`` (which does not exist)
+  or per-task codex-homes (tenant homes are per-project and shared,
+  and MCP seeding is worker-global), so an allowlist claim would be
+  false. What v3 does instead is fail fast on the opposite, silent
+  failure: a task that declares a required tool but whose tenant
+  codex-home config.toml has no ``[mcp_servers.<tool>]`` section
+  at dispatch time is marked failed before any model call, with the
+  missing tools named. The check runs only for tenant-isolated
+  Docker workers, where the tenant config.toml is the actual
+  availability record (worker flags alone would be wrong: a section
+  seeded earlier by another worker persists in the shared tenant
+  home). Local/cloud workers skip the check and are documented as
+  such, not as "tools verified".
+
+v9 (tool approvals, this file plus server/worker changes) adds a
+``tool_approvals`` field, and it is deliberately narrower than
+"per-tool approval enforcement" -- the execution layer cannot
+honour that today, and this track says so instead of claiming it:
+
+* Declaration: ``tool_approvals`` maps a known tool to one of
+  ``ask`` / ``auto`` / ``deny``. Unknown tools and unknown
+  policies are 400s. A tool declared both required (``tools``)
+  and ``deny`` is a 400: a task that must use a tool it must
+  never be allowed to use is a contradiction, not a policy.
+* What is NOT claimed: per-tool interception in host.py.
+  ``host.py _answer_server_request`` answers every elicitation
+  with one global switch (``approval == "auto"`` accepts,
+  anything else declines) and the elicitation message carries
+  no tool/server identity this codebase can rely on, so host
+  cannot tell which tool is asking. The approvals queue
+  (``cloud/approvals.py``) is record-only today: host runs in
+  a worker-spawned subprocess with no control-plane channel,
+  so there is no "ask the user" path at runtime. Credential
+  scope is NOT part of this field either: MCP credentials live
+  in the tenant codex-home config / env, per-project, not
+  per-task, and declaring a scope here without a channel to
+  enforce it would be the same kind of lie.
+* What IS executed: the declaration is validated at creation,
+  persisted (tasks.agent_tool_approvals, JSON object, NULL =
+  undeclared), echoed in GET and the creation response, and
+  at dispatch the worker audits the declaration together with
+  its effective outcome under today's host behaviour
+  (``effective_tool_approvals``): ``auto`` + host-auto accepts,
+  everything else declines, and ``ask`` is reported as
+  "decline (no ask channel)" -- never as "will ask". The
+  worker also re-checks the required+deny contradiction at
+  dispatch (defence in depth for rows written before v9 or
+  outside the API) and fails fast before any model call, in
+  the v3 tools-gate shape. Goal and coordinator tasks reject
+  tool_approvals at creation, like instructions: their turns
+  do not pass the declaration through, so accepting it there
+  would be a silent drop.

+"""Architecture-conformance checks for the control plane and for
+skill-driven projects (software-engineering skill, G2 frozen artefacts).
+
+Zero third-party dependencies; standard library only. This module
+imports no ``cloud.*`` module, so it can never violate the layer bans
+it enforces, and it can be reused verbatim against a skill project's
+own directory tree (see ``check_skill_project``).
+
+The four checks, each with a stated rule and a stated reason:
+
+1. Contract version (``check_contract_version``). Rule mirrors the
+   skill's contract-freeze change protocol: after freeze, a version
+   change is allowed only with a coordinator-approved change record
+   that names backward compatibility, the affected clients, and (for
+   a breaking change) a regression task per affected client; the
+   version must advance by exactly one. Reason: a silent contract
+   drift is how parallel client threads diverge; the protocol is the
+   only sanctioned path, so the check enforces the protocol instead
+   of merely documenting it.
+
+2. Forbidden directories (``is_within`` / ``check_task_writes``).
+   Rule reuses the two directory definitions that already exist and
+   invents no third one: on the control plane a task's own directory
+   is its tenant work directory (``worker._tenant_dirs`` ``work``);
+   in a skill project a client thread's own directory is its
+   ``apps/<client>/`` tree. Any write outside the own directory --
+   including ``..`` escapes and symlink escapes, both resolved before
+   comparison -- is a violation. Reason: cross-directory writes are
+   how one tenant/client corrupts another's worktree.
+
+3. Forbidden imports (``check_layer_imports``). Bans were chosen by
+   auditing the current tree, not by wishful layering; every ban
+   below passes on the baseline, and the repo-level test pins that:
+
+   - Foundation modules (``db``, ``models``, ``queue``,
+     ``logging_config``) must not import orchestration/service
+     modules (``server``, ``worker``, ``pr_exec``, ``webhooks``,
+     ``autoscaler``, ``cost``). Reason: the foundation is imported
+     by everything; an upward import is a cycle waiting to happen
+     and drags service state into pure helpers.
+   - The execution module (``sandbox``) must not import persistence
+     or orchestration (``db``, ``server``, ``worker``, ``cost``,
+     ``auth``, ``pr``, ``pr_exec``, ``webhooks``). Reason: executors
+     must stay swappable and testable with fake runners; decisions
+     about mounts and networks arrive as arguments, not by reading
+     the database.
+   - No cloud module except the driver-adjacent ones (``db``,
+     ``backup``, ``migrations``) may open a database connection
+     directly (``sqlite3.connect`` or any ``psycopg*`` import).
+     Service modules must obtain connections through
+     ``cloud.db.connect`` or a Store. Reason: the backend switch
+     (sqlite/postgres) lives in exactly one place; a direct driver
+     call bypasses it. Deliberately NOT banned: ``server.py``'s use
+     of ``sqlite3.Row`` / ``sqlite3.IntegrityError`` as type adapters
+     on connections obtained from ``cloud.db`` -- that is adaptation,
+     not a bypass, and banning it would fail the baseline for no
+     safety gain. The test asserts the narrow form (no ``connect``
+     call, no driver import) rather than the broad form.
+
+   Only static ``ast`` imports are seen; dynamic imports
+   (``importlib``) are out of scope and are noted, not claimed.
+
+4. Frozen stack (``check_frozen_stack``). Rule mirrors the skill's
+   G2 rule "frozen stack must not be swapped mid-flight": a client
+   whose stack entry changes, or disappears, after freeze fails
+   unless an approved change record covers it; adding a brand-new
+   client (no frozen entry) is an addition, not a swap, and passes.
+   Reason: the shared core is built against the frozen table; a
+   mid-flight swap silently invalidates it.
+
+All checkers return plain data (dicts/lists), never raise for a
+violation, so CI can report every violation in one run instead of
+stopping at the first.

+"""Lifecycle hook policy for the task-attempt ledger (audit gap 3
+follow-up: "which dispatch counts as an attempt, and who judges
+``is_defect``").
+
+This module is the CANONICAL policy text. The same policy is
+restated (shorter) in ``docs/arch-conformance-metrics.md`` and
+pinned by ``cloud/tests/test_attempt_hook.py``; if the three ever
+disagree, this module wins and the other two must be fixed.
+
+The problem it solves: audit gap 3 built the ledger but
+deliberately left the writer unconnected, because a naive writer
+-- one row per worker execution -- misclassifies exactly twice:
+it counts a platform auto-resume as an attempt, and it counts a
+transient retry as a defect. This module fixes the writer's
+trigger, not the ledger's math: ``aggregate_attempts`` is
+untouched by the hook (its only change in this track is the
+correction-row rule in ``attempt_ledger.py``), and the cost
+dual-column code (``cloud.cost``) is untouched entirely.
+
+POLICY (each rule is enforced in code below, not just prose):
+
+1. One counted dispatch = one row, at most. A dispatch that the
+   hook counts writes EXACTLY ONE ledger row, when its outcome is
+   known (terminal ``completed`` / ``failed`` / ``interrupted``,
+   or the goal-conversion case in ``worker.run_one``), with
+   ``is_defect=False`` always (rule 6). A dispatch that the hook
+   does not count writes NO row at all -- not even an
+   ``interrupted`` row -- so an uncounted dispatch can never
+   create the ledger table as a side effect.
+
+2. What counts as one attempt -- a logical agent round, not a
+   worker execution:
+   - First dispatch of a task: counts (``first_or_human_retry``).
+     It is the task's first agent round.
+   - Human ``/retry`` of a failed/interrupted/merge-failed task:
+     counts (same kind). A retry is a human-initiated new round:
+     new model work, new result, new cost. The server endpoint
+     leaves no marker behind, so the worker cannot distinguish a
+     retry from a first dispatch -- and does not need to, because
+     both count.
+   - Human ``/continue`` with a new message: counts
+     (``human_continue``). The message starts a new round on the
+     same session thread. Non-goal tasks and goal tasks opening a
+     NEW goal loop (``_resume_kind == "new-goal"``) are both here.
+   - Human breakpoint resume (``/goal-resume``, or ``/continue``
+     on an old-verify goal task, i.e. ``_resume_kind ==
+     "breakpoint"``): counts (``breakpoint_resume``) -- but as
+     the SAME logical round's row, not as an extra attempt. The
+     fragment that was interrupted wrote only an excluded
+     ``interrupted`` row (gap 3 rule), so the resume's terminal
+     row is the round's single counted row. A resume that ends
+     interrupted again writes only another excluded row: the
+     round is still pending, and still contributes zero counted
+     attempts. Rationale: one goal loop = one attempt, however
+     many executions the loop took; the interruption history
+     stays visible in the ``interrupted`` rows and in
+     ``auto_resume_count`` / audit / task_steps, not in the
+     attempt count. EXCEPTION (ordering, rule 4): when the
+     resume was itself platform-triggered, the platform marker
+     wins and the dispatch does NOT count -- a platform goal
+     auto-resume and a human goal-resume are the same loop
+     continuation, but only the human one is attributed to the
+     agent. That asymmetry is deliberate and uniform with the
+     platform rule below; flipping it is the listed user
+     decision, not a silent default.
+   - Coordinator parent dispatch: does NOT count
+     (``coordinator_orchestration``). The parent runs no model
+     round (``cost_record_id`` is None) and its terminal status
+     is an aggregate of its children; each child records its own
+     row through its own dispatch. Counting the parent would
+     double-count orchestration as an agent attempt.
+   - Platform auto-resume dispatch (worker
+     ``auto_resume_interrupted`` requeue, goal or non-goal):
+     does NOT count (``platform_auto_resume``). This is the
+     default the gap-3 track demanded, and it is UNIFORM: every
+     platform requeue is excluded, whether it continues a goal
+     loop or fresh-runs a non-goal task. Rationale: the platform
+     killed the previous execution and re-ran it without any
+     human or coordinator decision; attributing that execution
+     to the agent would punish platform instability in an
+     agent-quality rate. TRADE-OFF, STATED NOT HIDDEN: a task
+     whose terminal outcome came ONLY from platform dispatches
+     stays unknown in the ledger (no counted row), so it is
+     excluded from rate denominators -- the rates describe
+     tasks whose terminal outcome came from a human/first
+     round. The platform reruns themselves are NOT lost: they
+     are recorded in ``tasks.auto_resume_count``, the
+     ``worker_auto_resumed`` audit events, and the
+     ``task_steps`` ``auto_resume`` rows. The rejected
+     alternative was a separately marked ledger row that is
+     excluded from denominators: same denominator outcome, but
+     a second row kind, a new column, and aggregate exclusion
+     logic, for co-location only. If a future policy wants
+     platform completions counted as loop completions, the flip
+     is one line in ``classify_dispatch`` (platform + breakpoint
+     -> counted) plus tests -- it is listed as a user decision
+     in the track summary, not silently decided here.
+   - Pre-execution gate failures: do NOT count. A dispatch that
+     never reached the model -- missing key, repository
+     resolution failure, quota gate, goal-rounds cap, gateway
+     preparation failure -- is an admission rejection, not an
+     attempt. It writes no row (and no cost record either, which
+     is the existing behaviour); it stays visible in audit
+     (``worker_missing_key`` / ``worker_repo_failed`` /
+     ``worker_quota_stop`` / ``worker_goal_cap_rejected`` /
+     ``worker_gateway_failed``).
+   - Dispatches that never ran (budget gate, no ready task,
+     claim lost to another worker): do NOT count and are not
+     even classified -- ``run_one`` returns before the hook
+     runs, and no marker is consumed (see rule 4).
+
+3. Transient retries inside one dispatch are NOT new attempts.
+   The worker's ``max_retries`` loop, its one real fallback
+   re-run, its goal "already exists" breakpoint fallback, and
+   its follow-up drain all run inside a single ``run_one``
+   dispatch, share one cost aggregate, and produce ONE ledger
+   row: the dispatch's terminal outcome. An inner failure that
+   is later retried successfully leaves no failure row behind;
+   an inner failure that exhausts retries leaves one failure
+   row, not N. This is enforced by placement (the hook is
+   called once per dispatch, at ``run_one``'s terminal points)
+   rather than by counting executions.
+
+4. Platform identification -- the marker mechanism. The worker
+   that requeues a task is not necessarily the worker that later
+   claims it, so the origin must survive in the database, not in
+   memory. ``auto_resume_interrupted`` writes one marker row
+   (``task_attempt_origin_markers``) in the SAME transaction as
+   the requeue, with ``queued_at`` equal to the ``updated_at``
+   the requeue writes. ``run_one`` captures the queued task's
+   ``updated_at`` BEFORE claiming (claim overwrites it), and
+   after a successful claim consumes the marker ONLY if
+   ``queued_at`` still matches. Any intervening human action
+   (cancel, retry, continue) rewrites ``updated_at``, so a stale
+   marker can never misclassify a later human round: on
+   mismatch the marker is deleted as stale and the dispatch is
+   classified by its own fields. A claim that loses the race
+   consumes nothing, so the winning worker still sees its
+   marker. Marker writes and reads happen ONLY when the hook is
+   enabled; with the hook off, ``auto_resume_interrupted``
+   writes no marker and ``run_one`` reads none, so off behaviour
+   is byte-identical to gap 3 (no new table, no new row).
+   Marker-table creation is a write-path-only step, like the
+   ledger table itself; the read path (``GET /metrics-report``)
+   never touches it.
+
+5. Switch. ``Worker(attempt_ledger_hook=False)`` (CLI
+   ``--attempt-ledger-hook``), default OFF. OFF means: no ledger
+   row, no marker row, no marker-table creation, no ledger-table
+   creation from the worker -- exactly gap 3's "explicit calls
+   only" behaviour, including old tasks still returning ``None``
+   (unknown, not 0) and the read endpoint never creating a
+   table. ON means rules 1-4 apply. Enabling the hook
+   mid-flight has one documented edge: a task requeued by
+   auto-resume WHILE the hook was off carries no marker, so its
+   next dispatch counts as a human/first round (one extra
+   counted row for that in-flight task, once). That is the
+   fail-safe direction (a human round is the common case), and
+   it self-heals: every later requeue writes a marker.
+
+6. ``is_defect`` -- who judges, and how a wrong judgement is
+   fixed. The worker hook NEVER judges a defect: it always
+   records ``is_defect=False``. A failed dispatch is not a
+   defect (transient failures, quota stops, and cancelled rounds
+   all fail without being defects), and the worker cannot tell
+   a transient failure from a defect round at runtime -- so it
+   must not guess. The ONLY defect judgements in the ledger are
+   explicit ones, made at record time by an explicit recorder:
+   a human maintainer (or a coordinator review) calling
+   ``record_attempt`` / ``record_correction`` directly with
+   ``is_defect=True`` and a category. The bar for that authority
+   is maintainer-level (``approve_merge``, the same bar as
+   ``/retry``: both spend model money and move decision-grade
+   rates). A defect judgement made in error is corrected ONLY by
+   appending a correction row (``record_correction``): the old
+   row is never updated or deleted, corrections apply in
+   attempt order with last-wins, and a correction can only
+   change the defect judgement, never the outcome. There is NO
+   HTTP endpoint for marking or correcting defects in this
+   track -- the function is the interface, and an endpoint (with
+   the ``approve_merge`` permission check) is follow-up work,
+   listed as unconnected in the track summary. Until it exists,
+   defect marks come only from explicit, reviewed calls, never
+   from automation.
+
+7. Failure discipline. Every hook write is best-effort: a ledger
+   or marker failure is logged (``worker_attempt_ledger_failed``
+   / ``worker_attempt_marker_failed``) and NEVER fails the task,
+   blocks a requeue, or changes a task's status. The one
+   exception is validation inside ``record_attempt`` /
+   ``record_correction`` (bad outcome, defect on an interrupted
+   row, correcting a nonexistent attempt): those raise
+   ``ValueError`` BEFORE writing, by design, so ambiguous data
+   is never stored -- but the worker hook only ever passes
+   validated values (a terminal outcome, ``is_defect=False``),
+   so it cannot hit that path in normal operation.
+
+8. Postgres. The marker table follows the ledger table's manual
+   discipline: it is NOT created by ``init_postgres_schema``,
+   and ``PG_MARKER_DDL`` below is the exact statement to run by
+   hand on production Postgres (and verify) before enabling the
+   hook against a Postgres-backed control plane. Until that
+   step runs, marker writes fail (best-effort, rule 7) and
+   platform dispatches degrade to counted -- the same
+   fail-safe direction as rule 5's mid-flight edge, and the
+   reason the PG manual step is a precondition for enabling
+   the hook in production, not an afterthought. Real Postgres
+   verification was NOT done on this track (no local Postgres):
+   PG evidence here is adapter-level only (``?`` placeholders
+   translate to ``%s`` through ``cloud.db``, DDL uses only
+   Postgres-valid types, no autoincrement/identity column),
+   exactly like gap 3's PG evidence, and labelled as such.
+   Integration v2 out-of-box closure (see
+   ``cloud/ledger_onboarding.py``): the DDL checklist, the
+   explicit enable path and the read-only
+   ``verify_ledger_ready`` / ``ledger_setup_report`` probe
+   close the "hook off by default + manual PG DDL" gap
+   WITHOUT changing the default (still OFF) or auto-running
+   DDL on production Postgres -- the manual PG step remains
+   an operator action, now checkable instead of assumed.
+
+This module imports ``cloud.attempt_ledger`` only, opens no
+database connection itself (callers pass a connection in), and
+contains no ``sqlite3.connect`` / ``psycopg*`` import, so the
+``arch_conformance`` layer rules are untouched.

+"""Task-attempt ledger for the step-5 metrics loop (audit gap 3).
+
+Choice made here, with the trade-off stated rather than hidden:
+
+- This module adds a SEPARATE ``task_attempts`` table; it does NOT
+  add ``attempts``/``defects`` columns to ``tasks``. Columns would be
+  simpler to query (one row per task, no join), but they collapse
+  history into two counters: a task's per-attempt story (which
+  attempt failed, with what defect category, in what order) would be
+  unrecoverable, and widening the hot ``tasks`` table on production
+  Postgres is a heavier migration than adding a new, empty table.
+  The ledger costs one aggregate query at report time, and that
+  query is exactly what ``aggregate_attempts`` exists to pin down.
+- The ledger is append-only in intent: ``record_attempt`` only ever
+  inserts a new ``(task_id, attempt_no)`` row (``attempt_no`` is
+  ``MAX + 1`` per task, never reused). There is no update path, so a
+  recorded attempt cannot be silently rewritten into a first-pass
+  success after the fact.
+
+Semantics (pinned by tests, not left to each caller):
+
+- One row = one real attempt at the task. ``outcome`` is one of
+  ``success`` / ``failure`` / ``interrupted``.
+- ``interrupted`` rows are kept for audit but NEVER count toward
+  ``attempts`` or ``defects``: a platform interruption that
+  auto-resumes as a fresh run is a platform event, not an agent
+  failure, and the step-5 rule that ``interrupted`` is not a
+  terminal task status would be meaningless if the interruption
+  still inflated the attempt count. A task whose ledger holds only
+  interrupted rows has NO counted attempt, so it is omitted from
+  the aggregate entirely -- the endpoint then still reports its
+  rates as unknown (``None``), never as 0.
+- ``is_defect`` is set explicitly by the recorder, never inferred
+  from ``outcome``: a failed attempt is not automatically a defect
+  (a retry can fail for a transient reason without being a
+  defect round), and a defect round is a judgement the recording
+  caller makes. ``defect_category`` requires ``is_defect``; an
+  interrupted row can never be a defect. Both contradictions raise
+  ``ValueError`` instead of being stored as ambiguous data.
+- ``defect_category`` for a task (the single category that
+  ``compute_metrics`` carries per task) is the category of its
+  FIRST defect row in attempt order. Later defect rows still count
+  toward ``defects``; only the category label is first-wins, so it
+  is deterministic. Corrections (below) re-evaluate this label:
+  the first defect row AFTER corrections is applied wins.
+- A defect judgement can be CORRECTED, never rewritten:
+  ``record_correction`` appends a new row whose
+  ``corrects_attempt_no`` points at the attempt it corrects; the
+  old row stays untouched, and aggregation applies corrections in
+  attempt order with last-wins (so a wrongly marked defect can be
+  unmarked, and a defect missed at record time can be added after
+  review). A correction row is never itself counted as an
+  attempt, cannot change an attempt's outcome (only its defect
+  judgement), and cannot target an interrupted row, another
+  correction row, or a nonexistent attempt -- all raise
+  ``ValueError`` and write nothing. Who may correct is a policy
+  question answered in ``cloud/attempt_hook.py`` (explicit
+  recorder only, maintainer bar); the worker hook never writes
+  corrections and never marks a defect.
+- Old tasks have no ledger rows, and that is NOT backfilled: the
+  aggregate simply has no entry for them, the endpoint leaves their
+  ``attempts``/``defects`` as ``None``, and ``compute_metrics``
+  excludes them from rate denominators (they are neither counted
+  as first-pass nor as defect-free). Fabricating a row for an old
+  task (e.g. ``attempts=1, defects=0`` from "it completed") would
+  be inventing history.
+
+Persistence notes:
+
+- One table, one definition. ``task_attempts`` is defined ONCE
+  below (``TASK_ATTEMPTS_DDL``, aliased as ``SQLITE_DDL`` /
+  ``PG_DDL``); ``cloud.attempts`` (the resume-history writer) and
+  ``cloud.db.POSTGRES_SCHEMA`` (the fresh-Postgres schema) both
+  import this same string instead of carrying their own copy.
+  The two historical shapes -- main's resume DDL (``kind`` /
+  ``interrupted_reason`` / ``checkpoint_round`` / ``result_text``
+  / ``error_text``) and gap 3's ledger DDL (``outcome`` /
+  ``is_defect`` / ``defect_category`` / ``corrects_attempt_no``)
+  -- are superseded by this unified definition, which carries
+  both column groups. The shared columns (``task_id``,
+  ``attempt_no``, ``created_at``) had identical meaning and type
+  on both sides, so there is no semantic conflict to arbitrate:
+  the union of the column sets IS the unified schema, with one
+  deliberate relaxation (see below).
+- Row kinds in one table. A row is a ledger row iff ``outcome``
+  is non-NULL (written by this module, outcome validated in
+  Python before the insert); a row with ``outcome`` NULL is a
+  resume-history row (written by ``cloud.attempts``). The two
+  writers insert disjoint column groups and read by column name,
+  so they share the table without overwriting each other's
+  fields. ``aggregate_attempts`` counts ONLY ledger rows: a
+  resume row (outcome NULL) is skipped, never counted as a
+  defect-free first pass -- otherwise a task that was merely
+  auto-resumed would silently gain a counted attempt.
+- The one deliberate relaxation: ``outcome`` is nullable in the
+  unified DDL even though the ledger writer always supplies it.
+  A ``NOT NULL`` on ``outcome`` would make the resume writer's
+  insert (which has no outcome to report) fail on a fresh table,
+  so the constraint lives in Python validation here, not in the
+  DDL. ``is_defect`` keeps ``NOT NULL DEFAULT 0`` so a resume
+  row that omits it still reads as "not a defect judgement".
+- SQLite: ``ensure_task_attempts_table`` runs
+  ``CREATE TABLE IF NOT EXISTS`` with the unified DDL, then
+  migrates a pre-existing legacy table (old resume shape, gap-3
+  ledger shape, or the rehearsal-era 12-column shape) by adding
+  whichever unified columns it lacks. Added columns are always
+  nullable or defaulted, so existing rows are never blocked;
+  SQLite ``ALTER TABLE`` cannot tighten an existing column's
+  nullability, so a migrated table keeps its looser column
+  types -- the column SET and the data are unified, the
+  ``NOT NULL`` spelling on fresh tables is not retrofitted.
+  This is a migration to the single canonical definition, not a
+  second definition assembled at runtime.
+- Postgres: the production table is NOT created by
+  ``init_postgres_schema`` (deliberately: that schema is covered by
+  the migrations test asserting ``MIGRATION_TABLES`` equals the
+  schema set, and this ledger must not silently widen that set).
+  ``PG_DDL`` below is the exact statement to run manually on
+  production Postgres and verify (``\\d task_attempts`` or the
+  ``information_schema`` equivalent) before any Postgres-backed
+  endpoint is expected to return real rates. The DDL uses only
+  Postgres-valid types (``TEXT``/``INTEGER``/``DOUBLE PRECISION``),
+  a composite primary key, and no ``AUTOINCREMENT``/identity
+  column, so it needs no sequence handling; the parameterized
+  ``INSERT`` uses ``?`` placeholders, which the ``cloud.db``
+  Postgres adapter translates to ``%s`` (see the adapter test in
+  ``test_attempt_ledger.py``). Until that manual step runs, the
+  endpoint treats a missing table exactly like "no ledger rows":
+  unknown rates, not an error -- the same fail-soft shape already
+  used for missing ``cost_records``. The Postgres upgrade path
+  for a legacy-shaped table was verified against a real
+  Postgres 16.15 instance on 2026-11-06 (fresh ``PG_DDL``,
+  three legacy shapes migrated in place, both writers, PK,
+  idempotent ensure; see
+  ``verification/codex-task-attempts-pg-proof-20261106.md``).
+  One gap-3-only step relaxes a gap-3 table's ``outcome``
+  from NOT NULL with ``ALTER COLUMN outcome DROP NOT NULL``
+  (see ``ensure_task_attempts_table``); the statement works
+  on Postgres and on SQLite 3.53.0+, and is swallowed by
+  ``try/except`` on older SQLite, where the column stays
+  NOT NULL.
+- The read path (``GET /metrics-report``) never creates the table:
+  a read-only endpoint must not mutate schema. Table creation
+  happens only on the write path, inside ``record_attempt`` /
+  ``record_correction``.
+- Lifecycle hook (this track, see ``cloud/attempt_hook.py``):
+  the worker writes exactly one row per COUNTED dispatch (see
+  that module's policy for which dispatches count: human/first
+  rounds and human breakpoint resumes count; platform auto-resume
+  reruns, coordinator fan-out, and pre-execution gate failures do
+  not). The hook is OFF by default (``attempt_ledger_hook=False``):
+  with it off, this module's behaviour is exactly audit gap 3 --
+  the ledger fills only through explicit ``record_attempt`` /
+  ``record_correction`` calls, and production rates stay honestly
+  unknown until the hook is deliberately enabled. The worker hook
+  always records ``is_defect=False``: it never judges a defect,
+  so enabling it can never turn a transient retry into a defect.
+- Schema evolution note (unified schema, this batch):
+  the old resume DDL, the gap-3 ledger DDL, and the rehearsal
+  12-column shape are all legacy shapes of the SAME table.
+  ``ensure_task_attempts_table`` migrates any of them to the
+  unified column set in place (add missing columns only, never
+  drop or rewrite rows); the read path uses ``SELECT *``
+  deliberately so rows of any shape still read, and
+  ``aggregate_attempts`` treats a row without an outcome as a
+  resume row, not as a ledger attempt (see above).
+
+This module imports no ``cloud.*`` module and opens no database
+connection itself: callers pass a connection in, so the layer rules
+(``arch_conformance``: no direct driver connection outside
+``cloud.db``) are untouched -- there is no ``sqlite3.connect`` and
+no ``psycopg*`` import here at all.

+"""尝试账本（v6，Foundry“平台以原始输入重启”对应的另一半）。
+
+已有的、不在本轨重复造的机制（查代码确认）：
+- 任务创建幂等：tasks 的 UNIQUE(project_id, idempotency_key)，
+  重复创建回读已有任务，并发抢建靠 IntegrityError 回读。
+- goal 断点：task_checkpoints 每轮快照（worker 镜像线程 +
+  终局导入），goal 任务自动续跑走同一线程、同一 worktree、
+  从 goal_rounds_done 下一轮起；无进展熔断（断点轮次 3 次
+  不变即 stall）与退避、次数上限并存。
+- 合并与通知的 CAS：终局写回只在 running 时成功才写结果、
+  记成本、发通知，重复终局不重复记账发通知；协调员子任
+  务按分工名复用，不重复建。
+
+本轨补的缺口，恰恰是上述机制都没盖住的那一段：非 goal
+任务被平台中断后，auto_resume_interrupted 会把它全新重
+排——同一 worktree 里文件还在，但重排前会清掉 result_text /
+error_text / interrupted_reason，新一轮 agent 只拿到原始
+prompt，既不知道上一尝试做到哪一步、出了什么错，也无法
+区分“worktree 里已有的文件是上一尝试的产物还是仓库原有
+内容”，于是可能重复创建上一尝试已创建的东西。goal 任务
+不受此影响（线程连续性自带历史），协调员子任务也不受此
+影响（auto_resume 本来就不接 coordinator_orphan）。
+
+本轨只做三件可执行的事，全部在 worker/server 层，不改
+host.py、不改 codex 线程恢复：
+① 尝试账本 task_attempts：auto_resume 把任务回 queued
+  之前，先把正结束的这次尝试记下来——attempt_no（= 旧
+  auto_resume_count + 1，即正结束尝试的序号）、kind
+  （goal_breakpoint 或 platform_fresh）、interrupted_reason、
+  checkpoint_round（库中断点最大轮次，非 goal 恒为 -1）、
+  result_text / error_text 各截断 2000 字。记账与回 queued
+  在同一事务里，记账失败不单独炸恢复循环（外层已兜底），
+  但同一 (task_id, attempt_no) 重复记时 INSERT OR IGNORE
+  保留第一次，不覆盖。表定义是统一 schema（FLAG-1，
+  2026-11-05）：本模块不自带一份 DDL，CREATE_TABLE_SQL
+  与建表/迁移均取自 ``cloud.attempt_ledger`` 的
+  ``TASK_ATTEMPTS_DDL`` / ``ensure_task_attempts_table``，
+  与台账写路径共用同一定义；本模块写的行 outcome 为
+  NULL（恢复历史行，非台账计数行，见 attempt_ledger 对
+  aggregate 的口径）。
+② 重跑前言：非 goal 平台全新重排的任务在认领时，worker
+  在内存副本的 prompt 前贴一段上次尝试说明（原 prompt
+  不落库，与项目/待办/记忆注入同款只改内存副本），内容
+  是账本里的事实——第几次尝试、中断原因、断点轮次、上一
+  尝试部分输出与错误（各截断 1000 字）——并明确要求先查
+  worktree 现状再动手、对 worktree 外的产物先核查再创建。
+  goal 断点续跑、_resume 任务、协调员任务一律跳过（它们
+  已有会话连续性或不跑模型回合）；账本里查不到记录的老
+  任务原样返回，不编造。
+③ 时间线读回：GET /tasks/{id}/timeline 在 steps /
+  checkpoints 之外加 attempts 数组，项目 read 权限复用
+  时间线原有校验，只读不改。
+
+诚实边界（写进模块与交付，不宣称）：
+- 前言是指令不是保证：agent 仍可能重复创建，账本只能
+  降低重复概率，不能像创建幂等键、合并 CAS 那样硬保证
+  不重复。worktree 外的产物（分支、PR、发布等）账本不
+  追踪——它只记 DB 里已有的事实，不读 worktree、不调外
+  部 API；那些产物的硬去重仍靠各自已有的门（创建幂等键、
+  合并状态 CAS、分工名复用）。
+- 本轨不做 worktree 文件快照：快照路径因执行器而异
+  （local / Docker 租户 / cloud 的 worktree 位置不同），
+  在 worker 层硬做快照会把执行器差异漏进账本；agent 在
+  本轮里自己查 worktree 现状是更可靠的口径。
+- 手动重试（/retry、/continue 等）不经过 auto_resume，
+  故不记尝试账本、不贴前言——用户显式重试时由用户自己
+  在新消息里给上下文，本轨不替用户编造上一尝试说明。

+"""有界自动审计循环（audit loop），只对确定性门做自动循环。
+
+设计前提（先核实再动手，见模块末尾的“复用清单”）：
+生产代码里没有“审计员 agent”，所以这里的“审”只能是确定性
+检查的结果——测试/校验命令、能力门、干跑阻塞、迁移列、格式
+等可客观判定对错的门。主观审计（架构、设计、代码美观）绝不
+触发自动循环，只返回 needs_review，走人工。
+
+有界方案（用户已定，一字不差地落地）：
+1. 只对确定性门循环：Finding.kind 只能是 deterministic 或
+   subjective；subjective 一律 needs_review，不推回、不计轮。
+2. 推回包写死：每条 Finding 必须带 id、evidence、reproduction、
+   acceptance，四者缺一即 ValueError（调用方 bug，不进循环）；
+   PushbackPacket 带 round、findings、criteria（本轮结束后仍未
+   解决的验收标准，finding_id -> gate_or_None）。
+3. 上限 3 轮：round = 已发出的推回数；round < 3 且有 finding 才
+   推回，round >= 3 且仍有 finding 即升级（escalate），不再循环。
+4. 重审审全量：每轮必须重跑全部门；上一轮通过的门本轮未跑
+   即 gate_missing 升级；上一轮通过的门本轮变失败即 regression
+   finding，同样不得放行。
+5. 标准不得弱化：上一轮的 finding 只有在三种情况下才算解决——
+   本轮仍被报告（仍在解决中）、调用方以 fixed 传入已修复证据、
+   其关联 gate 本轮通过；否则该 finding 被丢掉即 standards_weakened
+   升级，绝不默许把标准越放越宽。
+6. 默认关闭：引擎只由 Worker.audit_loop_evaluate 显式调用，且仅当
+   任务字典含 audit_loop 真值时才启用；没有 env 开关——全局 env
+   会让所有任务悄悄启用循环，这是本设计刻意拒绝的。开关关闭时
+   run_one、auto_resume、协调员、goal 断点行为逐字节不变（本模块
+   不改 run_one，见 Worker 方法的文档）。
+7. 轮次持久化：状态存在 task_audit_loop_state 单行表（task_id 主键），
+   跨 worker 重启不丢；计数缺失或损坏时 fail-closed 到升级，绝不
+   默认循环。审计行（audit_log）是 best-effort，写失败会丢计数，
+   所以轮次绝不以审计行计数为准——这是不用审计行做持久化的原因。
+
+复用清单（核实结论）：
+- goal 的 verify_command：goal 任务已有的确定性校验门，本引擎
+  不重复造校验，只消费“门的结果”（gate_results）。
+- task_attempts 尝试账本：本引擎不复用它做轮次持久化，原因
+  是它的主键是 (task_id, attempt_no)，与 goal/platform 尝试共用
+  attempt_no 序号——audit_loop 若也用 attempt_no 记轮次，序号会
+  与已有尝试撞主键、被 INSERT OR IGNORE 静默丢掉，轮次就丢了。
+  因此按 attempts 的 DDL 手法（模块内 CREATE_TABLE_SQL +
+  ensure + db.py POSTGRES_SCHEMA + migrations 表清单 + server
+  初始化调用）另起单行表，序号冲突问题不存在。
+- task_followups：特意不复用——它是用户消息（用户含任务间互发），
+  把机器推回包写进 followups 会把机器包暴露给用户、混淆用户消息。
+  推回包由调用方持有（返回的 packet dict），不落 followups。
+- 协调员重排（UPDATE tasks SET status='queued' 带状态 CAS）：
+  调用方若要重排，用同一手法；本引擎本身不改任务状态、不重排、
+  不调 runner——状态变更属于调用方，引擎只给决策。
+- worker 的 fail-fast 门（能力门、工具门等）：本引擎不替代它们，
+  只在它们已经判定出的结果之上做“循环还是升级”的决策。

+"""Audit-of-audit sampling: human review of audit verdicts.
+
+Zero third-party dependencies; standard library only, no ``cloud.*``
+imports. All functions are pure: they return plans, verdicts and
+records, never auto-apply a correction -- applying a correction is a
+separate, recorded step (see ``handle_sampling_result``).
+
+This module implements the sampling half of the "audit itself must
+be audited" rule. It does NOT change the audit verdicts, the
+pushback/rebuild counters, or the golden-set approval flow; it only
+defines which audit cases a human must re-examine, and what happens
+when that re-examination finds the audit wrong.
+
+UNIFIED SAMPLING RULE (single rule; this module is canonical for
+selection, ``cloud/audit_pushback.py::select_audit_sample`` is only
+its record-shaped adapter -- there is no second rule):
+
+The scope of "mandatory" comes from track 3 (#244): golden-task
+records and rebuild / refreeze / escalation records. The drawing
+mechanism comes from track 5 (#238): seeded random draws with ceil
+rounding. Track 3's old deterministic "every 10th record" rule is
+superseded and removed: a batch of fewer than 10 ordinary records
+drew zero under it, and a position-known draw is predictable. The
+rates below are TEST DEFAULTS (``DEFAULT_*``), not approved
+production values; the production rates are still a user decision.
+Mandatory 1.0 is a rule, not a tunable rate.
+
+Sampling rules (all testable, none left to "regular review"):
+
+1. Mandatory sampling (ratio 1.0, never skipped). A case is
+   mandatory when ANY of these triggers holds (trigger order for
+   display and for the legacy single-trigger helper is golden,
+   rebuild, third-failure, refreeze, escalate):
+   - ``golden_task``: the case's task is in the human-approved
+     golden set (``task_id`` when present, else ``id``). A golden
+     task's records are mandatory whatever their kind -- an
+     ordinary pass verdict on a golden task is sampled, not just
+     its failures.
+   - ``rebuild``: any case whose audit decision was rebuild-from-
+     scratch (推倒重做). A rebuild destroys the old implementation
+     in the workspace, so its verdict must always be re-examined.
+   - ``third_failure_near_complete_still_failed``: a case whose
+     third failure was root-caused as near-complete (接近完成),
+     was given one targeted continuation round, and still failed.
+     This is the exact boundary where the "one more round vs
+     rebuild" judgement is most error-prone, so it is always sampled.
+   - ``refreeze``: a contract/design re-freeze record.
+   - ``escalate``: an escalation record.
+   A near-complete third failure whose continuation round SUCCEEDED
+   is not mandatory (the judgement proved itself), and a
+   near-complete first/second failure is not mandatory either (the
+   threshold is the third failure, per the rebuild rule). A
+   ``blocked_quota`` record is NOT mandatory under this rule (it
+   is not in track 3's mandatory kind list); it is sampled only
+   through the random tiers below.
+
+2. Random sampling of the rest, with the seed recorded:
+   - normal audit cases: default ratio 0.10;
+   - critical-path cases (``critical_path=True`` and NOT already
+     mandatory): default ratio 0.50 -- critical paths get a higher
+     rate, not a free pass. (Track 3's old ``critical_path``
+     reason label for mandatory kinds is retired: mandatory kinds
+     now carry their own trigger names, and ``critical_path``
+     means only this 0.50 random tier.)
+   Mandatory cases are removed from the random pools BEFORE
+   drawing, so they consume no random quota. The seed is part of
+   the plan: a sample selected without a recorded seed is not
+   reproducible and therefore not auditable. Selection is
+   deterministic given (cases, ratios, seed).
+
+4. One pass, no double counting. Selection partitions every case
+   exactly once: mandatory (all its triggers listed, one sample,
+   one sampling entry) or random-critical or random-normal. A
+   record that is both a golden task AND a rebuild is sampled
+   ONCE, with ``triggers == ["golden_task", "rebuild"]``; its
+   correction, if any, is a single record whose retrigger follows
+   the (original, corrected) verdict pair, not the trigger list --
+   triggers decide selection only, never the correction action.
+   Two different records (e.g. a triage record and the later
+   rebuild record for the same task) are two samples, not a
+   double count: deduplication is per record, not per task.
+
+5. Golden-set construction. The caller-supplied golden id set
+   must be built from human-approved, non-sample tasks only:
+   ``build_golden_task_ids`` applies both vocabularies -- a task
+   counts only with ``human_approved_by`` set AND none of
+   ``is_example``, ``sample=True``, or an id starting with
+   ``sample-``. Track 3's per-task approver rule and track 5's
+   sample-exclusion rule are both preserved; neither alone is
+   sufficient.
+
+6. Correction gate effect (shared with track 3 / wiring #247).
+   A sampling correction NEVER unblocks a merge by itself: a
+   correction to ``pass`` (a wrong block) schedules a re-audit
+   and the gate stays blocked until a new passing re-audit
+   conclusion exists; a correction to ``fail`` (a wrong pass)
+   re-triggers pushback and re-blocks at once. Vocabulary
+   synonyms for the same pair actions: track 3
+   ``retrigger_pushback_and_reblock`` == track 5
+   ``reopen_audit_and_pushback`` (wrong pass), and track 3
+   ``schedule_reaudit`` == track 5
+   ``cancel_pushback_and_rerun_audit`` (wrong block, where
+   "cancel" means cancel-and-rerun, never cancel-and-merge).
+
+3. Golden-set approval is separate from sampling and is NOT
+   satisfied by sample files: ``filter_golden_tasks`` drops any task
+   flagged as a sample (``sample=True`` or an id starting with
+   ``sample-``) and reports how many were dropped; a golden set
+   counts only its remaining, human-approved tasks. The approval
+   checklist (``golden_approval_checklist``) lists every item that
+   must be human-completed before a golden set is approved; until
+   then every item reads ``pending_human``.
+
+Handling a sampling result (``handle_sampling_result``):
+
+- Sampling says the audit was CORRECT: no correction, only a record
+  entry (the audit stands, with evidence it was re-examined).
+- Sampling says the audit was WRONG: the original conclusion is
+  corrected in the record, and the corresponding flow is
+  re-triggered:
+    - wrongly issued pushback -> ``cancel_pushback_and_rerun_audit``
+      (cancel the pushback, restore the pre-pushback state, rerun);
+    - wrongly issued rebuild -> ``halt_rebuild_and_restore``
+      (halt the rebuild, restore the original implementation from
+      git history/tag, rerun -- the old implementation is preserved
+      by the rebuild rule itself, so restoration is possible);
+    - wrongly issued pass (a failure the audit missed) ->
+      ``reopen_audit_and_pushback`` (reopen with the corrected
+      verdict and run the pushback flow the audit should have run);
+    - unknown original decision -> ``escalate_to_human`` (never
+      invent a retrigger).
+  Every outcome, correct or corrected, is appended to the
+  audit-of-audit record (``append_audit_record``); a sampling result
+  that is not recorded is treated as not having happened.

+"""Wiring between three already-landed tracks (no new semantics here):
+
+- track 1 (``cloud/merge_gate_hard.py``, PR #240): the hard merge
+  gate, five checks + branch protection, machine-readable ``blocks``
+  codes on its 409 response;
+- track 3 (``cloud/audit_pushback.py``, PR #244): the independent
+  audit + auto-pushback decision, the pushback package, and the QA
+  re-run rule;
+- track 4 (``cloud/ledger.py``, PR #241): the append-only hash-chain
+  ledger, the only durable store in this wiring.
+
+What this module owns, and nothing else:
+
+1.  Translation at the boundary. Track-3 field names and enums are
+    authoritative for callers; track-4 storage field names are
+    authoritative on the chain. This module translates, it does not
+    invent a second ledger schema:
+
+    ============================  ===================================
+    track-3 event                 chain record (track 4 action)
+    ============================  ===================================
+    audit verdict                 ``audit_verdict``
+    pushback round (pushed)       ``audit_pushback_round`` (pushed)
+    fix (landed, re-audit open)   ``audit_pushback_round`` with
+                                  ``fix_diff`` + package marker
+                                  ``wiring_event="fix"`` (evidence
+                                  row only; see the gate reader)
+    fix + re-audit                ``audit_pushback_round``
+                                  (re_reviewed, ``fix_diff`` +
+                                  ``re_review_result``)
+    rebuild decision / done       ``audit_rebuild``
+    third-failure triage          ``audit_third_failure_assessment``
+    test-change single audit      ``audit_test_change``
+    audit-of-audit correction     ``audit_meta_review``
+    rebuild notice / confirmation ``audit_rebuild_notice``
+    escalation / blocked quota /  ``audit_wiring_event`` (the one
+    audit sample                  compat action added to track 4
+                                  by this wiring; see below)
+    ============================  ===================================
+
+2.  CONDITIONAL mapping, done here and only here. Track 4 stores
+    verdicts as ``pass`` / ``fail`` only, and track 3 says
+    CONDITIONAL is not a pass. Every verdict (audit verdict and
+    re-audit verdict) that arrives as ``"conditional"`` -- or as
+    anything that is not exactly ``"pass"`` -- is stored as
+    ``"fail"``, with the original value preserved in
+    ``extra.original_verdict`` (verdict rows) or in
+    ``re_review_result.original_verdict`` (pushback rows). The
+    original conclusion is never overwritten: the chain keeps the
+    mapped value AND the original, and corrections are separate
+    ``audit_meta_review`` rows, never edits.
+
+3.  The gate reader (``pushback_block_for_task``). It replays a
+    task's chain rows in id order and returns a ``gate_block()``-
+    shaped dict (``merge_blocked`` / ``release_blocked`` /
+    ``blocked_by="audit_pushback"`` / ``round`` / ``failed_checks``,
+    plus a ``modules`` detail map). ``cloud/server.py`` ANDs this
+    with the hard gate's own five checks: either side blocks and
+    the merge returns 409 with the task status unchanged. The
+    pushback block applies in every gate mode -- an open audit
+    pushback is not something a ``record``-mode caller can confirm
+    away, and ``merge_gate_confirm`` never touches it.
+
+4.  The gate-blocks-to-package bridge
+    (``pushback_package_from_gate``). A hard-gate 409's ``blocks``
+    codes are machine input to the pushback package: each code maps
+    to a track-3 gate check (``ci_*`` -> ``ci_green``,
+    ``directory_*`` -> ``directory_isolation``,
+    ``contract_*`` -> ``contract_version``,
+    ``coordinator_*`` -> ``coordinator_approval``,
+    ``review_*`` / ``unresolved_review_comments`` ->
+    ``unresolved_review_comments``). Branch-protection codes have
+    no track-3 gate-check member, so they travel as the extra check
+    name ``"branch_protection"`` in the package's failed items --
+    they are never dropped, and they are never disguised as one of
+    the ten checks. Callers must take the codes from the 409
+    ``merge_gate`` object, never by parsing audit detail text.
+
+Known translation losses (stated, not hidden):
+
+- Track 3 distinguishes root causes ``"contract"`` vs ``"design"``;
+  track 4 stores only ``"implementation"`` / ``"contract_design"``.
+  Both contract and design map to ``"contract_design"`` on rebuild
+  rows (track 3's rebuild branch treats them identically: refreeze,
+  no code rebuild). The finer distinction survives on escalation
+  rows, which carry the original ``root_cause`` verbatim.
+- Track 3's third-failure triage verdict ``"early_refreeze"`` has
+  no track-4 assessment determination (only ``early_rebuild`` /
+  ``continuation_round`` exist there). It is recorded as an
+  ``audit_wiring_event`` of kind ``escalate_refreeze``, never
+  forced into an assessment row with the wrong determination.
+- Track 3's ``"unknown"`` root cause has no track-4 value and is
+  refused (``ValueError``) rather than guessed: a rebuild row must
+  say which side the root cause is on.
+- A fix-only row is counted by track 4's timeline summary inside
+  ``pushback_rounds`` (that summary counts rows, and a round
+  already spans two rows there). The gate reader skips fix rows
+  for state transitions, so the count wart cannot unblock or block
+  a merge by itself.
+
+What this module does NOT do:
+
+- It does not change any track-1 / track-3 / track-4 semantic:
+  hard stays fail-closed by default, protection unknown /
+  unprotected still block in hard mode, confirmation still never
+  covers a directory violation, the chain stays fail-closed and
+  append-only, and the cost dual-column rule is untouched.
+- It does not create pushback subtasks, send notices, or run
+  fixes. ``record_*`` only appends chain rows; deriving a fix
+  subtask from a package is the caller's job (track 3's
+  ``build_pushback_package`` already describes its shape).
+- It does not gate ``deploy.py``. There is no server-side release
+  endpoint in this codebase: the merge endpoint is where
+  ``merge_blocked`` is enforced, and ``release_blocked`` is
+  returned alongside it so a future release endpoint can enforce
+  it with this same reader. Deploy remains an operator action
+  outside this wiring.

+本模块绝不复制 #215 的文件，只把 CHV 真正能映射的

+即是机械的（见 docs/chv-architecture.md ADR-8）。

+- gates.resolve_inside(base, rel)：目录门，CHV 快照/磁盘
+  路径白名单正好需要它——本模块实现同语义并已在
+  hardening.validate_snapshot_url 里使用，#215 合并后
+  改为 from cloud.gates import resolve_inside 即可。
+- sandbox_policy.tmpfs_isolated(executor_kind, path)：CHV
+  客机 /tmp 落在客机磁盘上，不是宿主 tmpfs，故对
+  cloud-hypervisor 一律返回 (False, ...)——fail-closed，
+  绝不宣称隔离。未知执行器同样 fail-closed。
+- timeouts.resolve_module_timeout / quota.decide：无映射。
+  前者是审批/队列超时（None=不过期、0=不过期），CHV
+  的 api/ready 超时是秒数且 0 无效，语义不同，硬套会
+  改行为；后者是按月美元配额，CHV 的配额是 VM 数/磁盘
+  GB/快照数，单位不同。两者在本模块里 deliberately
+  不提供，测试钉住“CHV 不 import 它们”。

+  不得再本地复刻。CHV 语义是“一律不隔离（fail-closed）”，
+  若 #215 版对 cloud-hypervisor 返回 True，替换即改行为，
+  必须先停下来核对，不得机械替换。
+- R3 timeouts / quota：永不替换。#215 的 timeouts 是

+本轨（feat-chv-arch-maint-fe）破环性清理：WarmPool 从
+cloud/chv/pool.py 移到本文件，cloud/chv/__init__ 与
+cloud/sandbox.py 不再 re-export 它，生产代码 import 本
+模块即违规（见 docs/chv-architecture.md ADR-12 的禁
+

+`from cloud.chv.experimental_pool import WarmPool`。

+reconcile_orphans_for_executor()，它不 import 本模块。
+
+定案（架构决策，见 docs/chv-architecture.md ADR-5）：WarmPool
+不再宣称为生产快速启动特性。原因：预热 VM 的磁盘是干净快照
+盘，不是任务盘；dispatch 前查池若要真正接线，必须在派任务
+前给已暂停 VM 重新供给任务盘（热换盘/二盘挂载/host.py 磁盘
+语义三者都未实现），把预热盘直接当任务盘用会击穿“任务盘
+隔离”不变量。acquire 内 resume 只是实验性接口，worker
+dispatch 永远走冷启动（wake_vm），_run_with_vm 绝不查池。
+本模块的 reconcile_orphans() 只留给实验/旧测试直接调用；
+生产启动/关闭走 orphans facade，不再经本类。
+warm_pool_wired_to_dispatch 恒为 False，任何把它改成
+True 的改动都必须先实现任务盘重供给并补不变量测试，
+否则不得合入。
+
+
+隔离红线（与 #216 一致，绝不妥协）：预热条目是一次性的
+干净快照 VM，acquire 消耗掉它，release 一律销毁，绝不把
+一个任务用过的 VM（带任务文件、带 agent 痕迹）翻出来给
+下一个任务/租户复用；池子空了就回落冷启动（wake_vm），
+绝不因为池空就降级 Docker/Local。
+
+Registry（本轨新增）：
+- 文件：state_dir/warm-pool.json（registry_path 可覆盖），
+  内容为 {<合成名>: {"state", "vm", "task_id", "snapshot_url"}}。
+  每次 prewarm/acquire/release 后立即落盘（临时文件 + 原子
+  rename），worker 崩溃后重启仍能发现上一世的条目。
+- 载入时绝不复用：新池实例从 registry 读到的条目一律标为
+  orphan（不计入 warm_count，acquire 绝不发给任务），因为
+  旧 VMM 进程已随旧 worker 消失，无法验证它还是当初那个
+  干净快照 VM。它们只能走 reconcile_orphans() 清理。
+- reconcile_orphans()：worker 启动/清理时的显式入口，对
+  每个 orphan/assigned 条目尽力调 executor.shutdown_vm
+  （清 socket 与残留登记），条目清掉并落盘，返回已清理的
+  VM 名列表。registry 里没有的残留 socket 仍由执行器的
+  cleanup_stale_vms() 扫 state_dir 处理，两者互补，不互相
+  替代；reconcile 绝不在构造时自动执行（同一 state_dir 只
+  能有一个活池，构造时自动清理会误杀另一个活池的 VM）。
+- 损坏 fail-safe：registry 不是合法 JSON / 顶层不是 dict 时，
+  整个文件 quarantine 成 <path>.corrupt（尽力而为），池子
+  从空开始，绝不用损坏数据复用 VM；单条目结构非法时只
+  丢该条（记 registry_corrupt_entries），不连坐其它条目。
+  registry 写失败时只记日志警告、不炸任务流（池子内存态
+  仍可用，重启后孤儿改由 socket 扫描兜底）。

+绝不进 argv/日志/镜像。
+

+   同款口径；CHV 是单租户单 VM 模型，一台宿主对应一个
+   Gitea 身份。密钥来源绝不硬编码进代码。
+2. 任务级覆盖（内存态）：任务 dict 的 `gitea_sync` 子 dict，
+   键即 6 个变量名。仅在调用方以内存态构造任务 dict 时生效
+   （直接调 wake_vm、测试、手工驱动）；tasks 表目前没有

+  一台 VM 泄漏即全网可冒充，属安全事故。
+- 每 VM 一次性生成：宿主在 VMM 启动前为该 VM 生成一对
+  ed25519 host key（私钥只活在该 VM 的 seed 里，随 VM

+  执行器在 VM 启动前就已钉死，启动后 SSH 直接用该文件
+  校验，换 key 即拒绝——不再靠启动后 ssh-keyscan 抓到的
+  key 来“事后钉死”。
+- 私钥注入通道（选 cloud-init NoCloud，写清唯一通道）：
+  seed 目录 state_dir/<vm>/seed/ 含 meta-data（instance-id
+  即 VM 名）、user-data（write_files 写 /etc/ssh/ 的 host

+  NoCloud seed、首启时先应用 seed 再启动 sshd、且不得在
+  seed 应用前/后无条件重新生成 host key（否则预置即失效）。
+  seed 磁盘/目录是 per-VM 敏感物，VM 关闭/回收时必须删。
+- 回落边界：ssh-keyscan 首次捕获只作弱回落
+  （CHV_HOST_KEY_MODE=keyscan，且文档标为弱方案）：

+安全模型（本轨的核心变化，替代 #216 的
+StrictHostKeyChecking=no + UserKnownHostsFile=/dev/null）：
+
+- 每 VM 一个独立 known_hosts 文件：
+  state_dir/<vm 名>/known_hosts（与每任务磁盘同目录，
+  任务销毁时不自动删——known_hosts 留在宿主 state_dir 里，
+  供事后审计该 VM 当时钉死的 key；VM 名本身已含任务 id，
+  不会串到别的 VM 上）。
+- 首次信任（TOFU，边界必须写清，不假装是强验证）：
+  首次启动时客机 host key 未知，执行器用 ssh-keyscan 经
+  宿主转发端口（127.0.0.1:<port>，只走本机回环）抓一次
+  当时呈现的 key，写入该 VM 的 known_hosts 文件；此后
+  同一 VM 的每次 SSH 都用 StrictHostKeyChecking=yes +
+  该文件校验，VM 被替换 / 中间人换 key 时 SSH 直接拒绝，
+  不再静默接受。首次捕获本身不验证“这台客机就是我们要
+  的那台”——它只防首次之后的替换；更强的方案是镜像构建
+  /cloud-init 时把客机 host key 预置进 known_hosts（未来
+  工作，见 docs/chv-production-readiness.md 的待办），本轨
+  在 mock 测试里只能验证“捕获→写文件→后续命令带钉死
+  选项”的管线，绝不声称 mock 验证了首次密钥的真实性。
+- 密钥红线不变且收紧（feat-chv-secfix，H2/M1）：argv 里只有
+  key 文件路径，绝无 key 值；网关密钥类变量（见
+  _CHV_SECRET_ENV_NAMES，与 Docker 的 _DOCKER_SECRET_ENV_NAMES
+  同款“只传名”口径，但 CHV 更进一步：值连宿主子进程环境
+  都不进，改走 seed 盘里的客内文件，见 hostkeys.write_seed）
+  出现在 extra_env 里时本函数直接 ValueError——传输层
+  fail-closed，任何调用方都不能再把密钥值拼回 argv。
+  非密钥 extra_env 仍可走 env 前缀（值在 argv 里可见，
+  但按定义不是密钥）。
+- 远程 shell 转义（feat-chv-secfix，M1）：SSH 协议的 exec
+  请求本身是一条字符串，ssh 客户端把多个参数用空格拼成
+  远程 shell 命令——此前 inner 参数原样进 argv，prompt 里
+  的 ;/$()/引号/换行会在远程 shell 里被二次解析。现在每个
+  远程 token 都经 shlex.quote 引用后仍以列表元素形式返回
+  （ssh 拼接后远程解析结果与本地 list 语义一致）；客内

+ * on. Anything the UI probes but we do not provide is reported once on the

+# relay-config.json — mock 现状与接真实 relay
+
+`relay-config.json` 保持 UI 栈自带的 Bumian 配置原样，未换 provider、未写任何密钥值。
+
+## 当前状态：模型调用走本地 mock
+
+- `baseUrl` 是 `http://127.0.0.1:8095/mockrelay/v1`：app-server 的模型请求由本机 `host/mock-model.mjs` 用确定性替身回答，不出本机、不产生真实调用、不花钱。
+- `relayBaseUrl`（`https://www.bumianapi.top/v1`）只写在 JSON 里，host 代码没有引用它，当前不生效。
+- `apiKey` 为空字符串：真实 relay 需要 key 时，key 值绝不写进本文件。
+
+## 接真实 relay：两步
+
+1. 把 `baseUrl` 的值改为 `relayBaseUrl` 的值（即 `https://www.bumianapi.top/v1`）。
+   只改这一处；`providerId` / `providerName` / `model` / `wireApi` / `envKey` 不动。
+2. 在启动 UI host 的环境里设置 `BUMIAN_API_KEY` 环境变量（key 值只进环境，不进文件、不进仓库）：
+   `BUMIAN_API_KEY=<你的 key> scripts/run-codex-ui.sh`
+
+改完后 app-server 启动时按 `relay-config.json` 的 `-c` 覆盖走真实 relay；`chatgptBaseUrl`
+仍指向本机 `/mock`，插件目录、账号端点、遥测等 ChatGPT 后端调用继续由本地替身回答。
