-（Playwright accessibility.snapshot），不见原始 DOM，不能在页面
-上下文跑 JS，不暴露 evaluate/content，不开 DevTools。
+对齐 Muse P4（见 docs/chv-muse-p4-gap.md）：本文件源自 P2 的
+chv-browser.py（c61484a），P4 在此基础上重构——子代理不再直连
+Playwright/Chromium，Chromium 的所有权在单元外 CDP broker
+（chv-cdp-broker.py）手里；本进程只是 broker 的客户端。
+
+子代理只向单元返回页面无障碍树快照（Playwright

-  open       {url}   -> 导航并返回 {title, url, a11y, truncated}
-  snapshot   {}      -> 当前页的 {title, url, a11y, truncated}
-  screenshot {}      -> 截图落盘 /run/chv/shots/<uuid>.png，返回 {path}
-  close      {}      -> 关当前页（浏览器进程继续跑，等下一次 open）
+  open       {url}   -> 经 broker 导航并返回 {title, url, a11y,

+  screenshot {}      -> 截图落盘，返回 {path}

-URL 只允许 http/https；localhost 与私有地址字面量直接拒绝（主机名
-判定，不做 DNS 解析——DNS 重绑定防护是 P3 Sentinel 的事，这里不
-冒充已做）。无障碍树截断到 200 节点 / 64KB，超了标 truncated=true，
-绝不把整棵树无上限灌进 socket。
+暂停时除 ping/resume/status/list_asks/resolve_ask 外一切操作
+拒绝——用户接管或凭证注入填表时，代理完全不能行动。
 
-playwright 是懒加载：import 本模块不需要 playwright 已装（单测
-在无 playwright 环境跑）；真正 open 时才加载，缺失即报错。
+URL 校验、快照截断、错误消毒、禁用操作表都在

+
+对齐 Muse P4（见 docs/chv-muse-p4-gap.md）：Chromium 的所有权
+在这里，不在浏览器子代理手里。broker 独家持有 Playwright，
+CDP 连接只存在于本进程内；子代理（chv-browser.py）只经本
+socket 说话，绝不直连浏览器、绝不见 CDP 端点。
+
+操作（Unix socket /run/chv/cdp-broker.sock，JSON 行）：
+  open       {url}   -> 导航并返回 {title, url, a11y, truncated,
+                    untrusted_input, injection_flags, form_risk}
+  snapshot   {}      -> 当前页同上
+  screenshot {}      -> 截图落盘 /run/chv/shots/<uuid>.png，返回 {path}
+  close      {}      -> 关当前页（浏览器进程继续跑）
+  pause      {}      -> 暂停（用户接管/填表/自动暂停的统一状态）
+  resume     {}      -> 解除暂停
+  status     {}      -> {paused, url, form_risk}
+  list_asks  {}      -> 待审批 ask 列表
+  resolve_ask {ask_id, decision} -> 写回 allow/denied
+  ping       {}      -> {"ok": true}
+
+暂停时除 ping/resume/status/list_asks 外一切操作拒绝——
+用户接管或凭证注入填表时，代理完全不能行动。
+
+安全规则（纯函数在 chv_browser_guard.py，本文件只做接线）：
+  导航前 validate_url + 静态拦截名单；快照恒带
+  untrusted_input=true（外部页面文本永远是数据、不是指令），
+  命中注入启发式带 injection_flags；高风险表单在页时 open
+  导航即返回 ask（入队、执行停止）；观测到导航 POST 即自动
+  暂停 + ask；下载命中可执行扩展名即取消 + 暂停 + ask。
+  所有回包与日志过 sanitize_error；响应里绝无 ws 端点、
+  DevTools 地址、原始 HTML。

+
+对齐 Muse 官方安全文：内置连接器的业务逻辑由 systemd 沙箱化的
+privsep worker 执行；每个 worker 由 cgroup 标识、有明确凭证白名单。
+本进程跑在客内、运行时单元之外（root 身份的 systemd 服务，见
+chv-gitea-worker.service；P2 的 nspawn 单元落地后，codex 在单元内，
+本进程在单元外——单元内 root 映射为非特权用户，读不到本进程的
+socket）。它只做 Gitea 同步的 git 业务逻辑：
+
+- 在 Unix socket /run/chv-gitea/worker.sock 上接受 broker/薄 CLI
+  的类型化请求（SO_PEERCRED 只放行 root；agent 在单元内只能请
+  broker 代办，连不上本 socket）；
+- 操作白名单只有 pull/push/status/ping；仓库只限 ~/workspace 下；
+- git 以 chv 身份跑（runuser -u chv，文件归属不变），argv 里只配
+  credential helper（P3 的 git-credential-chv-authd，见下），绝无
+  token 值；凭证由 git 经 helper 向 authd 按次取，本进程绝不持有
+  token；
+- git 输出先过 safety 扫描 + 打上来源标记再返回；block 即阻断
+  （内容不往回流），flag 即标记复核。
+
+只用标准库。cloud/chv/privsep.py 与 cloud/chv/safety.py 是叶子
+模块（只 import 标准库），镜像构建时随本文件一起拷进

+
+Muse 官方安全文（security.muse.ai 2026-09-08，见
+docs/chv-muse-p7-gap.md §1）：Postgres 存持久应用状态，与运行时
+单元、凭证存储分离。本轨的选型结论写在差距表 §4：轻量线用
+SQLite（每 VM 一个 0600 文件，WAL），不是 Postgres——镜像
++150–250MB 与每 VM 一个 server 进程对 2GB 轻量 VM 太重；宿主侧
+共享 Postgres 会把多用户状态集中到宿主，破坏每用户 VM 隔离。
+
+与 Postgres 的差距（诚实写明）：无多写者服务器、无网络访问、
+无行级安全、无内置复制（复制 = 备份/恢复路径）。DDL 用两方
+共通的受限子集（TEXT/INTEGER/REAL 列、TEXT id、无
+AUTOINCREMENT、无 SQLite 专有语法、参数化查询），换 Postgres =
+换连接工厂 + 同一份 DDL。
+
+分离保证：
+- 库文件只活在宿主 `state_dir/<vm>/app-state.sqlite`，不在客机
+  磁盘镜像里，nspawn cell 物理上够不着（测试钉住）。
+- 凭证绝不进库：所有写操作过无凭证守卫（键名 + 值模式双重
+  检查）；守卫拒绝时只报键名/模式，不含值。唯一例外是
+  round-12 新增的 ``kv_put``（P8 登记文档含用户 prompt，
+  prompt 里合法出现密钥样文本是调用方的事，旧 JSON 后端
+  同样不过守卫；见 kv_put 的 docstring）。
+- audit 表只追加：本模块不提供任何删除/修改审计的方法。

+
+接 Muse 官方要求（报告 §2.6）：确定性 UI——结构化审批卡
+（明确接受/拒绝动作）；审批是严格能力，绑定特定连接器/
+目的地与用例，支持一次性、会话级、任务级、时限级、永久级
+授权，Sentinel 决定向用户呈现哪几种授权类型；审批 UI 不在
+对话内，Sentinel 直接向客户端发审批请求，用户答复直接回
+Sentinel（防止对话内容伪造审批）。

+
+Muse 口径（见 docs/chv-muse-p5-gap.md §1 污点出口行）：用 eBPF
+cgroup 程序做网络拦截与进程归因、及挂在 LSM hook 上的 eBPF
+程序做污点传播。
+
+本模块只含两样东西，绝不冒充已加载：
+1. eBPF 程序源码（字符串常量，见 `EBPF_CGROUP_EGRESS_C` 与
+   `EBPF_LSM_TAINT_C`）：cgroup egress 拦截 + 进程归因 map +
+   LSM hook 污点传播骨架。源码本身不是“已在拦截流量”。
+2. 加载器 `EbpfTaintLoader`：能力探测（内核版本、bpffs、
+   CAP_BPF/CAP_SYS_ADMIN、bpftool/clang 是否在位）→ 状态
+   loaded/degraded/blocked + 原因；加载失败一律明确降级为
+   “策略引擎 + 代理层钩子”模式（`FALLBACK_MODE`），绝不把
+   degraded 写成 loaded。
+
+加载成功的硬条件（缺一即 blocked/degraded，不重试蒙混）：
+- 内核 >= 5.8（cgroup_skb egress 挂载点；LSM hook 另需
+  内核开 CONFIG_BPF_LSM，见 LSM 源码头注释）；
+- /sys/fs/bpf 存在且可写（pin 落点）；
+- 进程有效能力集含 CAP_BPF（bit 39）或 CAP_SYS_ADMIN
+  （bit 21）——且 bpf() 系统调用本身不被 seccomp 挡；
+- bpftool + clang 在位（编译与加载工具链）。
+
+本机实测结论（2026-11-07，Muse VM）：不行。内核
+7.0.0-43-generic、CapEff 含 CAP_BPF 与 CAP_SYS_ADMIN，但
+bpf() 与 BPF_MAP_CREATE 均报 EPERM（Seccomp filter 在位，
+4 条过滤器），且无 /sys/fs/bpf、无 bpftool/clang。能力位
+在位不等于系统调用放行——探测只看 CapEff 会误判，所以

+  `_run_with_vm` 起 VM 前调 `check_inference_call`：allow 才继续；
+  deny/ask 一律审计 + 停止，不起 VM。
+- provider=`sub2api` 时 origin 取 `SUB2API_BASE_URL`；provider 为空
+  （xcmapi 路径，codex 用自身 config.toml 默认网关）时执行器看不
+  到 origin，改取 operator 显式配置的 `CHV_INFERENCE_ORIGIN`，未配
+  即 ask（fail-closed，不静默放行）。部署迁移见差距表 §2.5。
+- 能力说明：allow 时带出的严格能力（单次、300 秒）是**起 VM 前的

+  `/home/chv/memory`（workspace 之外，不同步到 Gitea）。

+对齐 Muse 官方安全文（security.muse.ai 2026-09-08，见
+docs/chv-muse-p10-gap.md）：支付时发行一次性卡号给商家而非
+真实卡号，绑定特定商家、特定金额、有限有效期；已保存支付
+凭证的网站每次购买都弹人工审批并展示确切购买详情；未购物
+过的网站走内置合规钱包（Stripe Link 首发、Shop Pay 次之）。
+
+本模块只做客内 agent 侧的支付安全门（检测、路由、限额、
+审批、绑定、审计），不产生真实扣款：
+- ``PaymentCredentialVault``：已保存支付方式的隔离存储，
+  走 P3 authd 模式（只活内存、白名单、按次释放绑定、审计
+  绝无凭证值），但另立库——只存不透明支付方式 id + 掩码
+  标签，原始卡号 PAN 拒绝入库；
+- ``OneTimeCard``：一次性卡号的绑定与兑现校验（商家 +
+  金额 + 货币 + 有效期，单次有效）；
+- ``SimulatedWalletBackend``：沙箱钱包（假 PAN 只在后端
+  私有内存里，调用方只见掩码标签与 card_id；``charge``
+  只记账不联网），供测试与演示；真实钱包集成是待用户
+  另行批准的事项，见差距表 §3；
+- ``PaymentGate``：编排——结账检测 → 路由 → 限额 →
+  P5 对话外审批（确切购买详情进 payload）→ 铸一次性卡
+  → 兑现校验 → 记账 → 审计。无审批的支付一律拒绝。
+
+真实一次性虚拟卡由 Link 在其侧发行（连接器文档原文），
+本轨的卡是绑定与兑现校验的等价模型，不是发卡行。

+"""P8 swarm：子代理群——建群、派代理、隔离、工具注册与审计。
+
+对齐 Muse B3（官方安全文）：启动成群的子代理、构建自己的工具；
+VM 需要足够资源处理并发子代理与 crons。资源上限是本项目自定
+（见 docs/chv-muse-p8-gap.md §4），不是 Meta 官方值。
+
+隔离模型：每代理一个独立任务 id + 独立工作区（父任务工作区下
+按代理 id 分目录，`resolve_inside` 门守着）；代理之间互不可见
+对方工作区（`check_agent_path` 否定测试钉住）。真正执行在代
+理自己的 VM/单元里（P1 常驻池 + P2 单元是底座），本层只做登
+记、派发与审计，不执行工具代码。
+
+存储：宿主级 AppStateStore（round-12 已迁移，见
+docs/chv-muse-p8-gap.md §6）：state_dir/app-state.sqlite 的
+``p8-swarm`` 命名空间，一行存整份登记文档（原子写由 SQLite
+事务保证）；旧 swarms.json 首次加载时自动导入并改名
+``.migrated``；KV 行损坏/库打不开时回空结构（fail-safe，

+"""Usage metering and tier quota enforcement (P11).
+
+Four metered dimensions: tokens per month, messages per day,
+concurrent tasks, storage bytes. Tokens are read from the existing
+``cost_records`` ledger (``cloud/cost.py``) -- the inference channel's
+bookkeeping point -- never re-collected on a second path. Messages,
+task starts/ends, storage snapshots and warnings are recorded in the
+hash-chained ``usage_ledger`` table in this module.
+
+Tier limits and prices are a PROJECT PROPOSAL, not user-confirmed
+pricing and not Meta official pricing: the user delegated the numbers
+("set them by market", 2026-11-06) and never confirmed them. Every
+payload this module returns carries ``proposal: True``. Real billing
+(Stripe / payments / invoicing) is NOT in this module and must be
+approved separately; nothing here charges money.
+
+Admission semantics: gates are admission-only. A denial returns a
+``quota_exceeded`` dict (HTTP 402 at the server layer); there is no
+API here that terminates an in-flight turn. The pre-existing USD
+quota path in ``cloud/server.py`` still cuts in-flight work at turn
+boundaries via worker polling -- that is a known, documented
+discrepancy (see docs/chv-muse-p11-gap.md §5), not something this
+module silently resolves.
+
+Token gate counts ``source="actual"`` rows only, matching the
+``cost.py`` P1 decision ("estimated rows are never real spend and
+must not trip the cap"); estimated tokens are reported separately
+and labelled as estimates.

+# CHV VM 运营访问边界说明（feat-chv-muse-p9）
+
+> 口径依据：Meta 官方安全文（security.muse.ai 2026-09-08）对 Muse 当前架构的
+> 明确表述——当前架构**通过运营政策限制 Meta 人员访问用户数据，但并不阻止
+> Meta 在必要时为支持、保障或运营服务而访问数据**；“连 Meta 也看不到”是未来
+> Confidential VM 的目标，**截至 2026-11-01 的公开材料中未见 Confidential VM
+> 已全面上线**。本文件把同一口径落到本项目：只写文档 + 审计钩子，
+> **不冒充技术上不可访问**。
+
+## 1. 谁能访问 VM 内数据
+
+| 访问方 | 能访问什么 | 边界 |
+|---|---|---|
+| 用户本人（VM 属主） | 全部：工作区文件、记忆、凭证替身、审计记录 | 属主即所有者；可检查、编辑、下载 VM 内所有文件，也可要求忘记指定内容（见 P7） |
+| Agent（codex，单元内） | 任务所需的工作区与工具输出 | 受 nspawn 单元（P2）、authd 替身凭证（P3）、Sentinel 出口审批（P3/P5）约束；真凭证与宿主侧数据对单元内不可见 |
+| 宿主运维（部署机器的 root / codexsvc） | VM 磁盘镜像、state_dir、日志、审计 | **技术上可以访问**：宿主侧持有磁盘文件与进程，OS 账户即边界。本文件不声称运维看不到——只规定运维**应在什么情况下**访问（见 §2），并要求访问留审计 |
+| Meta（对照口径） | 不适用——本项目无 Meta 侧运营方 | 本项目是用户自部署，不存在 Meta 人员访问；写这一行只为对齐口径：若未来托管化，边界按同一句话执行 |
+
+## 2. 运维访问规则（政策，非技术强制）
+
+1. **日常不看**：运维不主动翻看用户工作区文件、对话记录与记忆；只看任务级元数据（任务 id、起止、成败、耗时）与审计事件。
+2. **排障可看**：任务失败、VM 异常、安全事件调查时，运维可查看相关 VM 的日志、审计记录与任务输出；查看行为本身记入审计（`chv_audit` + 操作日志）。
+3. **凭证永不直接取**：真凭证（Gitea token、网关 key）只经 authd 替身释放；运维排障需要凭证时走替身铸发流程，不直接读 seed 文件；seed 文件 0600，属主 root/codexsvc。
+4. **数据不出宿主**：排障取证不出部署机器；必须外发时先去标识化（任务 id 可留，对话原文、文件内容、密钥一律去掉），并记审计。
+5. **删除即删除**：用户要求删除任务数据/记忆时，运维删除 VM 盘、state_dir 与相关遥测行，并记审计；备份里的副本按备份保留期滚动清除，不单点恢复。
+
+## 3. 审计（可查的证据）
+
+- 任务生命周期审计：`chv_audit`（执行器 `_emit`，失败落盘 `chv-audit-spill.jsonl`）。
+- 出口审批审计：Sentinel 决策记录（`sentinel_egress_allow/deny/ask`，只含目标描述与原因，不含值）。
+- 训练开关审计：`training-opt-audit.jsonl`（开关变更时间、开/关、操作方）。
+- 遥测：`telemetry.jsonl`（只含任务级元数据字段，见 `docs/chv-muse-p9-gap.md` §2.1）。
+
+审计记录里绝不含凭证值、对话原文与文件内容；审计失败不中断任务（worker 层 best-effort 语义，见执行器 `_emit` 注释）。
+
+## 4. 广告隔离（口径，不用写代码）
+
+- 本项目不把用户对话或 VM 数据分享给任何广告系统；遥测字段白名单里没有可用于广告画像的字段。
+- Agent 浏览互联网时表现为用户活动，可能间接影响用户在别处看到的广告（与 Muse 官方口径一致）——这是浏览行为本身的副作用，不是本项目分享数据。
+
+## 5. 明确未做的事
+
+- **Confidential VM**：未做。Meta 自己也未交付（路线图），本项目不自研密码学隔离 VM；当前边界是 OS 账户 + 文件权限 + 审计，不是密码学不可访问。任何“连运维也看不到”的说法在本架构下都是错的，不要这样对外写。
+- **端到端加密记忆**：未做。记忆文件在 VM 盘上明文存放（权限 0600），依赖磁盘与宿主访问控制。
+- **操作审批 UI**：运维访问的审批流程目前是人工约定（本文件），没有强制审批卡；强制审批是后续工作，不在本轨冒充已实现。

+# 对齐 Muse P10 差距表：支付安全（凭证隔离 + 结账检测 + 每次购买人工审批 + 一次性卡号）
+
+依据：`~/workspace/research_notes/meta-muse-ai-architecture-20261101-0755/report.md`
+（官方以 Meta security.muse.ai 2026-09-08 为准；第三方转述要标注
+来源性质，不得把转述写成官方承诺）。Muse 官方支付安全要求
+（报告 §3.3，）：购物是最常见浏览器用例之一，Meta 对此
+格外谨慎——已保存支付凭证的网站，浏览器内置结账页检测，每次都
+弹出人工审批并展示确切购买详情；未购物过的网站，Muse 内置合规
+钱包，首发合作 Stripe Link，Shop Pay 即将来临；支付时发行一次性
+卡号给商家，而非真实卡号；该凭证绑定特定商家、特定金额、有限
+有效期，即使经提示注入被盗也“不太有用”；Muse 是首个被 Link 购买
+保障覆盖的 AI 代理（损坏/丢失商品免费保障、降价保障、免费退货、
+符合条件购买的退货保证——保障条款以 Link 官方为准，本轨不编
+细节、不实现理赔流程）。
+
+连接器文档补充（wallet tools 的实际口径，见
+`/opt/hatch/connectors/stripe-link/CONNECTOR.md`、
+`shop-pay/CONNECTOR.md`、`shopify-ucp/CONNECTOR.md`）：
+Link 在一次购买获批后注资一张一次性虚拟卡，商家永远收不到真实
+卡号；Shop Pay 原生路由用一次性 token、卡片路由在审批后才由浏览
+器填卡字段；每次购买走独立 browser task 与独立审批；审批被拒即
+停止、不扣款；结果未知时不重试、不换卡、不换路；取消待支付会
+void 虚拟卡；已完成扣款无钱包退款、走商家退款流程；直接结账须
+先查限额（每笔/每日/30 天，minor units、无货币、不换算），限额
+不可用时不编造上限；step-up 未完成时 Link 要求用户先验证身份；
+子代理、群聊、定时任务没有 wallet tools，不能替用户设 Link 或选
+支付方式。**本轨的结论：钱包能力在主应用运行时侧，不在
+`cloud/chv` 代码里；本轨只做客内 agent 侧的支付安全门（检测、
+审批、绑定、审计），真实钱包调用是待批准的集成点，见 §3。**
+
+本轨范围只限 P10：支付安全。起点是 P3（authd 替身凭证）与 P5
+（对话外审批通道），已合入本分支（合并 feat-chv-muse-p5，
+25bcd35）。不碰 P1（常驻 VM、气球、vsock）、不碰 P2（nspawn
+单元、浏览器子代理本体）、不碰 P4（浏览器完全对齐——结账检测
+与它接线，不重复造）、不碰 P6（privsep worker）、不碰 P7/P8/P9。
+分支 `feat-chv-muse-p10`（从基线 `06c3e17` 分出，合入 P5 后
+HEAD 为 `25bcd35`）。
+
+## 0. 起点（P3/P5 已做的，本轨不重写）
+
+- P3 `cloud/chv/authd.py`：`CredentialVault`（只活内存、白名单、
+按次释放绑定 {连接器, 主机, 仓库路径, 操作}、单次 + 300 秒
+TTL、审计绝无凭证值）+ `mint_gitea_token`；白名单只认
+`gitea`/`GITEA_TOKEN`，支付不在其中——本轨不改 authd 的
+白名单，支付凭证另立 `PaymentCredentialVault`（同模式，不
+同库，见 §1），避免把支付键混进代码仓库凭证的白名单。
+- P3 `cloud/chv/sentinel.py`：`ApprovalQueue`（ask 记入内存态
+待审批，`resolve` 只标记不放行）；`EgressRequest.describe()`
+只含连接器/目标/方法——支付审批借用这条队列记账，目标描述
+为 `connector=payment, method=purchase, scheme=https,
+host=<商家主机>, port=443, path=/checkout`。
+- P5 `cloud/chv/approval_channel.py`：对话外审批通道
+（`ApprovalRequest.payload()` + `Answer` + HMAC-SHA256 签名
++ `verify_answer` 五项校验 + `resolve_via_channel` 单次消费；
+对话内容里出现的“批准”字样一律无效）。本轨只给它加一个
+可选 `details` 字段（确切购买详情进 payload、供客户端 UI
+展示），校验与消费逻辑一字不动。
+
+## 1. 现状 vs Muse
+
+| 项 | 现状（实测/代码为准） | Muse 目标 | 本轨做法 |
+|---|---|---|---|
+| 支付凭证隔离 | 无。`cloud/chv` 里没有任何支付代码；agent 若要支付，只能把卡号/钱包凭证以明文塞进环境或对话——这正是 Muse 明令禁止的形态 | 凭证与 OAuth token 存于用户 VM 内独立隔离容器，不在其他服务中；登录凭证存入单元外的安全凭证存储，代理不可见，仅在需要时注入 | `cloud/chv/payments.py`：`PaymentCredentialVault`（只活内存、白名单 `stripe-link`/`shop-pay`、只存不透明支付方式 id + 掩码标签；原始卡号 PAN 拒绝入库——13–19 位数字串 + Luhn 校验命中即拒；按次释放绑定 {商家, 金额, 货币}、单次 + TTL；`__repr__`/审计绝无凭证值；`forget` 删凭证并作废未兑现释放） |
+| 结账页检测 | 无。浏览器侧 P2 的 `chv-browser.py` 只有 open/snapshot/screenshot/close/ping，无结账概念；P4 在做高风险表单拦截（`detect_form_risk` 扫无障碍树，密码/支付字段即标 `form_risk`），尚未提交 | 浏览器内置结账页检测 | `cloud/chv/checkout_detect.py`（纯函数，标准库）：`detect_checkout(url, a11y_nodes)`——URL 信号（/checkout、/payment、/pay、/order-review 等）+ 无障碍树信号（卡号/有效期/安全码字段、“下单/支付”按钮、金额文本）；返回 `is_checkout`/`confidence`/`reasons`/`form_risk`/`amount_text`；确定性规则，不冒充模型分类器；只读 a11y 节点，绝不读原始 DOM；与 P4 的 `detect_form_risk` 同输入形状，P4 的 broker 在高风险表单提交前调本检测（接线点见 §4，P4 未提交前先留接口 + 测试） |
+| 每次购买人工审批 | 无。没有任何“购买前停下”的机制 | 已保存支付凭证的网站，每次都弹出人工审批并展示确切购买详情 | `PaymentGate.begin_purchase`：结账检测未命中即拒；路由（见下行）；限额检查（见下行）；经 P5 通道发审批，payload 的 `details` 含确切购买详情（商家、商品、数量、金额、货币、钱包提供方）；审批只走通道答复，对话内“批准”无效；`complete_purchase` 先验签（`verify_answer`，不消费）、再验购买详情摘要（`PurchaseDetails.digest()`，篡改即拒且审批保持待处理）、最后 `resolve_via_channel` 单次消费；审批被拒即停止，不扣款 |
+| 一次性卡号 | 无 | 支付时发行一次性卡号给商家而非真实卡号；绑定特定商家、特定金额、有限有效期；被盗也“不太有用” | `OneTimeCard`（绑定 {商家, 金额, 货币, 有效期}，单次兑现；换商家/超额/过期/复用一律拒 + 审计）；`SimulatedWalletBackend`（沙箱钱包：假 PAN 只在后端私有内存里，调用方只见掩码标签与 card_id；`charge` 只记账不联网；取消即 void）；真实一次性虚拟卡由 Link 在其侧发行（连接器文档原文），本轨的卡是绑定与兑现校验的等价模型，不是发卡行——见 §3 |
+| 钱包路由 | 无。连接器文档有 stripe-link / shop-pay / shopify-ucp 三条路由，但 `cloud/chv` 里无路由逻辑 | 未购物过的网站走内置合规钱包，首发 Stripe Link，Shop Pay 即将来临 | `PaymentGate` 路由：商家有已保存凭证 → 已保存凭证路由；无 → 合规钱包路由，stripe-link 优先、shop-pay 次之；两家都不支持 → 拒绝（`no_wallet_route`），不编造路由。**来源时间差**：报告写于 2026-11-01 时 Shop Pay 是“即将来临”，连接器文档（当前）显示 Shop Pay 已可用；本轨按连接器文档现状写优先级，并在此标注时间差 |
+| 限额 | 无 | （连接器文档）直接结账须先查限额：每笔/每日/30 天，minor units、无货币、不换算；限额不可用时不编造上限 | `SpendLimits.check(amount_minor)`：三档逐项比 minor units；超任一档即拒（`over_limit`，审批前就拒）；三档全为 None（不可用）→ 通过但记 `limits_checked=False`，绝不编造上限 |
+| 支付审计 | 无 | 审计轨迹展示已做与计划做的事 | `PaymentAudit.record`：事件（`payment_approval_requested` / `payment_approved` / `payment_denied` / `payment_completed` / `payment_refused` / `payment_cancelled` / `payment_card_voided`）+ 允许字段（商家、金额、货币、掩码标签、pending_id、原因）；字段名命中 `card_number/pan/cvv/token/secret/password` 一律丢弃并标 `redacted=True`；卡号与凭证值绝不进审计 |
+
+## 2. 改了什么（本轨交付物）
+
+- `cloud/chv/checkout_detect.py`（新，标准库）：`CheckoutVerdict` + `detect_checkout(url, a11y_nodes)`（URL 信号 + 无障碍树信号 + 金额文本抽取；支付字段即 `form_risk=payment`、密码字段即 `form_risk=password`；页面文本只作展示信号，扣款金额永远以 `PurchaseDetails` 为准——页面文本是不受信任输入，见 P6 口径）。
+- `cloud/chv/payments.py`（新，标准库）：`PaymentCredentialVault` + `PaymentRelease` + `OneTimeCard` + `SimulatedWalletBackend` + `PurchaseDetails`（`digest()` 防篡改）+ `SpendLimits` + `PaymentAudit` + `PaymentGate`（编排：检测 → 路由 → 限额 → 审批 → 铸卡 → 兑现校验 → 记账 → 审计）。
+- 接线（`cloud/chv/approval_channel.py`，最小扩展）：`ApprovalRequest` 增加可选 `details` 字段，`payload()` 有 details 时才带上；`request_approval` 增加可选 `details` 参数；`verify_answer`/`resolve_via_channel` 一字不动；P5 既有测试不受影响。
+- `cloud/tests/test_chv_muse_p10_checkout.py`、`test_chv_muse_p10_payments.py`、`test_chv_muse_p10_gate.py`（新测试，含否定测试：无审批不支付、审批详情被篡改即拒、一次性卡号换商家/超额/过期/复用被拒、原始卡号拒绝入库、凭证泄露面为零、对话内伪造批准无效、答复重放无效、超限额审批前即拒、限额不可用时不编造上限、取消即 void 卡）。
+
+## 3. 诚实边界（本轮不宣称的东西）
+
+1. **真实支付不做，零真实扣款**：全部用沙箱/模拟钱包与假卡号
+（Stripe 测试卡号段 `400000000000xxxx`）验证，不联网、不调
+任何真实钱包接口。真实 Link / Shop Pay 集成（wallet tools
+是主应用运行时能力，不在 `cloud/chv` 代码里）列为**待用户
+另行批准**的事项，本轨不产生任何真实扣款、不持有任何真实
+卡号。
+2. **一次性卡号的“发行”在本轨是模拟**：真实一次性虚拟卡由
+Link 在其侧发行（连接器文档原文：“Link funds a one-time
+virtual card”）；本轨的 `OneTimeCard` 是绑定（商家 + 金额
++ 货币 + 有效期）与兑现校验的等价模型，不是发卡行。不要把
+“模拟钱包铸了测试卡号”写成“已接通 Link 发卡”。
+3. **购买保障只作口径引用**：Link 购买保障（损坏/丢失、降价、
+免费退货、退货保证）的 eligibility 由 Link 判定、理赔走
+Link；本轨不实现理赔流程、不承诺任何一笔购买受保障，保障
+条款以 Link 官方页面为准。
+4. **结账检测是启发式，不是 100% 检出**：URL 特征 + 无障碍树
+特征；商户自定义结账页、单页应用内嵌结账可能漏检。漏检时
+的安全底线是：无审批的支付一律拒绝（`PaymentGate` 拒绝
+任何未经审批的扣款），不宣称“所有结账页都会被拦下”。
+5. **限额检查依赖钱包侧返回的限额**：限额不可用时不编造上限，
+只记 `limits_checked=False`；审批仍须过。不要把“限额未知”
+写成“限额已校验通过”。
+6. **钱包路由优先级按连接器文档现状**：报告（2026-11-01）写
+Shop Pay“即将来临”，连接器文档（当前）显示 Shop Pay 已可
+用；本轨按连接器文档现状写 stripe-link 优先、shop-pay 次之，
+并标注了这一时间差；若连接器文档滞后于实际，以实际钱包
+能力为准。
+
+## 4. 真机待验证清单（未做，排队在 round-11 与 P4～P9 之后）
+
+1. P4 的 broker 接线：高风险表单提交前调 `detect_checkout`，
+结账页命中时 `open` 导航返回 `ask` 并暂停（与 P4 差距表
+§4 的 `form_submit` ask 种类对齐）。
+2. 真实钱包集成（待用户另行批准）：wallet tools 的
+`list_payment_methods` / 审批单 / `approved_card` 回包与
+`PaymentGate` 的对接；`payment_method_changed`（用户在
+审批单里换卡）时详情摘要重算与重新审批。
+3. 真实商户结账页上的检测命中率抽查（Shopify / Stripe
+Checkout / 常见电商各一例），漏检样例记入回归。
+4. 限额读取：`wallet.get_user_info` 的三档限额与本轨
+`SpendLimits` 的对接；限额不可用时的表现。
+5. 取消与未知结果：取消待支付 void 虚拟卡；结果未知时不重试
+的端到端表现（须真实钱包侧配合）。

+  “不是 relay 的账单”；`report_by_task/project/day`，**无 `report_by_user`**。

+
+## §3 改动清单（本轨）
+
+1. `cloud/usage.py`（新，标准库 + `cloud.db` / `cloud.cost` 的常量口径，
+   不引 server）：
+   - `TIER_LIMITS`：三档提案数值，模块 docstring 与每个返回 payload
+     都标注 `proposal: true`（提案，非定价）。
+   - `TierStore`：`user_tiers(user_id PK, tier, updated_at)`，`get_tier` /
+     `set_tier`（非法档位名拒绝）；**无档位行的用户不受档位门约束**，
+     只受既有 USD 配额约束——定档是管理员显式操作，不给存量用户
+     默认套 Free（否则上线即拦住所有人）。
+   - `UsageLedger`：`usage_ledger` 追加写哈希链账本（`prev_hash` +
+     `entry_hash = sha256(规范 JSON)`），`record` / `sum_kind` /
+     `verify_chain`（篡改返回首个坏行 id）。记消息、任务起止、存储
+     快照、提醒事件；**token 事件不重复记**（见第 2 条）。
+   - `UsageMeter`：月度 token（读 `cost_records` JOIN `tasks`，与
+     `_quota_status` 同款查询，actual / estimated 分开列）、当日消息
+     （读账本）、并发（注入 `running_task_count`，状态 `queued` /
+     `running`）、存储（注入 `storage_bytes`，磁盘实测）。
+     `summary(user_id)`：四项 used / limit / remaining + 提醒 + 账本
+     校验结果。
+   - `QuotaGate`：`check_task_admission`（token + 并发 + 存储）、
+     `check_message_admission`（消息/天 + token/月）。返回 None 放行，
+     否则否决 dict（`error: quota_exceeded` + `dimension` + `limit` /
+     `used` + 可读 `detail`）；**纯准入判定，无任何终止在跑任务的
+     API**（进行中回合不掐断，见 §5 第 1 条）。
+   - `disk_usage_bytes(path)`：递归求和，不跟随符号链接，读错跳过
+     （尽力而为，调用方在 payload 里标明实测范围）。
+   - 提醒阈值默认 0.8，环境变量 `CLOUD_USAGE_WARN_RATIO` 可配；
+     每维度每窗口只记一次提醒（账本 `kind="warning"` 去重）。
+2. token 计量口径：以模型方返回为准（`source="actual"`）；无返回时
+   字符估算（`source="estimated"`，payload 标注为估算）。**档位门只计
+   actual**——与 `cost.py` 的 P1 决定一致（“Estimated rows are never
+   real spend and must not trip the cap”）；estimated 只展示、不拦人。
+   但 payload 同时列出 estimated 数，让用户看得见估算占比。
+3. `cloud/server.py` 接线（只动配额漏斗，不新增调用点）：
+   - `_reject_if_over_quota` 内、USD 门与无价 cap 通过后，加档位门
+     （同一 `quota_user_id`）；档位查询异常同样 fail-closed 回 503。
+     `_reject_if_over_quota_for_task` 不动（它已委托给前者，双人门
+     自动覆盖）。
+   - `GET /users/me/usage`（`_user_usage_self`）：当期用量与剩余额度
+     + USD 配额合并返回 + 提醒 + 账本校验结果。
+   - `GET/POST /admin/tiers`（`_admin_tiers_get/set`，`_is_global_admin`
+     同款鉴权）：管理员定档 / 查档。
+   - 存储实测：复用 `_task_worktree_for_files` 逐任务解析本机 worktree
+     求和；cloud / cloud-hypervisor 任务不在本机，量不到，计 0 并在
+     payload 里标明 `storage_measured_tasks` / `storage_total_tasks`。
+4. `cloud/tests/test_usage_quota.py`（新）：档位数值钉住提案、非法档位
+   拒绝、无档位行不限档位门、token actual/estimated 口径、消息固定
+   UTC 日窗口、并发门、存储门与清理指引、账本哈希链与篡改发现、提醒
+   只发一次、准入纯判定不碰在跑任务、服务端点（`/users/me/usage`、
+   `/admin/tiers`、档位门 402）。
+5. `docs/chv-production-readiness.md`：补 P11 一节。
+
+## §4 真机待验证清单（未做，排队在 round-11 与 P4～P9 之后）
+
+- 真实 token 回传下的月度累计与 402（actual 行累计、无价模型走
+  既有 cap 不走美元门）。
+- 并发门在真实多任务下（建第 N+1 个任务被拒，在跑任务不受影响）。
+- 存储门在真实 worktree 下（本机任务目录求和、cloud 任务不计入）。
+- 80% 提醒在真实使用下只发一次、跨窗口重置。
+- 账本在真实写入压力下的链完整性（并发写不丢链不断）。
+
+## §5 诚实边界（本轨内不解决，写清不冒充）
+
+1. **进行中回合的语义不一致（已知待决）**：设计文档 §6.2 与本轨
+   任务书说“进行中的回合不中途掐断”；但基线 `_check_quota` 的
+   docstring 与 worker 实现是另一套——Local popen 与 Docker 路径的
+   worker 轮询每 30 秒查一次 USD 配额，超限杀进程组/容器（掐断粒度
+   是轮次边界 + 30 秒检查）。本轨新增的四项档位门**只做准入**，
+   不改既有 USD 路径的轮询掐断；两处语义不一致是已知待决项，
+   不在本轨内悄悄统一，须由父级另行裁决。
+2. **并发超限的处理与设计文档不同**：设计文档 §6.2 说并发超限
+   “新任务排队，不立即拒绝”；本轨任务书（父级指令）说“即拒并
+   给出可读原因”。本轨按任务书即拒，差异记在此。
+3. **存储计量不完整**：cloud / cloud-hypervisor 任务的 worktree
+   不在本机，量不到；本机也只能按任务 worktree 求和，用户在
+   VM 内或其它路径的占用不在计量内。payload 标明实测范围，
+   不冒充全量。
+4. **Heavy 消息/天提案未给**：提案原文只给了 Heavy 的 tokens /
+   并发 / 存储，未给消息/天。本轨定为不限，并标注为**本项目决定**，
+   不是提案原文、不是官方口径。
+5. **窗口口径**：token 按 UTC 自然月（与既有 USD 配额一致）；
+   消息按 UTC 自然日（固定窗口，非滑动）；并发与存储是瞬时值。
+   固定窗口边界存在少量跨窗毛刺，文档写清，不冒充滑动窗口。
+6. **价格与计费**：档位价格是助手提案（用户委托按市场定，未确认），
+   不是用户确认定价，更不是 Meta 官方定价；payload 与文档都带
+   `proposal` 标注。真实计费（Stripe/支付/开票/充值）不在本轨，
+   待用户另行批准；任何把“记账”等同于“收费”的说法都是错的。
+7. **token 价格**：USD 换算沿用 `cost.py` 的 OpenAI 挂牌价表，
+   注释明言不是 relay 账单；无价模型（无价格表项）的 token 只
+   计量、不折算美元，仍走既有无价 token cap。

+# 对齐 Muse P12 差距表：审计轨迹与活动视图
+
+依据：`~/workspace/research_notes/meta-muse-ai-architecture-20261101-0755/report.md`
+（官方新闻室、安全文 2026-09-08、设计文为准；第三方拆解只作参考，
+不得把逆向细节写成官方架构）。基线：06c3e17。
+
+## 1. Muse 官方要求（报告原文口径）
+
+| # | 要求 | 来源 |
+|---|------|------|
+| R1 | 完整审计轨迹（audit trail）展示已做与计划做的事 | 新闻室、设计文（报告 §2.2 第 7 步） |
+| R2 | 头像下方显示正在做什么的摘要，点头像可见完整活动日志与已批准权限 | 设计文（任务简报口径；报告未逐字展开，列为设计文要求） |

+| R5 | 用户可自由检查、编辑、下载 VM 内所有文件，包括 Muse 关于用户的记忆 | 安全文（报告 §3 凭证与数据政策） |
+
+## 2. 现状（基线 06c3e17）
+
+- 审计是散的：`cloud/auth.py` 的 `AuthStore.audit()` 只追加
+  `(user_id, project_id, action, detail, created_at)` 到 SQLite
+  `audit_log` 表，`list_audit()` 只按项目倒序取；`cloud/worker.py`
+  的 `Worker._audit()` 是 best-effort 包装；`worker_adapter.py` 的
+  `make_chv_audit_callback` 把 CHV 事件转成 `(project_id,
+  "chv_vm_" + event, detail)`。没有统一记录模型，没有“已做/计划
+  做”汇总，没有活动视图，没有已批准权限清单，没有导出。
+- 审批侧：P3（分支 feat-chv-muse-p3，提交 a90cf78）有
+  `ApprovalQueue`（内存态 pending 记录：目标描述 + 原因 + ts）；
+  P5（分支 feat-chv-muse-p5，提交 25bcd35）有对话外审批通道
+  `approval_channel.py`（nonce + 15 分钟过期 + HMAC-SHA256 签名，
+  答复只能用一次）与 `ScopedCapability.describe()`（能力绑定描述）。
+  但 P3/P5 都不在本基线里，本轨不能 import 它们，只能按 dict
+  契约接线，集成时由 round-11 合并。
+- 状态存储：P7（feat-chv-muse-p7）正在做状态分离，本轨审计轨迹
+  的持久化先落独立 JSONL 文件 + 明确标注待迁移到 P7 存储，
+  不重复造 P7 的库。
+
+## 3. 本轨改什么
+
+- `cloud/chv/audit_trail.py`（新，纯标准库）：统一审计记录模型
+  （时间/主体/动作/对象/结果/原因/关联任务/关联审批/项目）；
+  追加写 JSONL + SHA-256 哈希链（改写/删除/调序可被 `verify()`
+  发现）；字段级白名单清洗（密钥、token 值、对话原文绝不进
+  审计，否定测试钉住）；事件分类覆盖任务派发、VM 生命周期、
+  同步、审批、支付（P10）、配额（P11）、记忆操作（P7 的忘记）、
+  后台任务（P8）、推理/遥测（P9）；`from_legacy_row()` 把现有
+  `audit_log` 行转成统一记录（标 `legacy: true`，无哈希链）；
+  导出选 JSON（不做 CSV，见 §5）。
+- `cloud/chv/activity.py`（新，纯标准库）：计划登记（已做 vs
+  计划做：pending/running/done/cancelled，非法流转拒绝）；
+  已批准权限登记（接 P5 `describe()` 形状：连接器/主机/用例/
+  档位/有效期/次数余量/撤销）；`activity_summary()` 纯函数拼出
+  正在做摘要 + 近期已做 + 计划清单 + 已批准权限数。
+- `cloud/chv/approval_card.py`（新，纯标准库）：结构化审批卡
+  数据（动作/目标/原因/风险分级/接受与拒绝两个明确动作/五档
+  授权类型选项，永久档标注须显式 opt-in）；`card_matches_channel()`
+  校验卡数据与 P5 通道载荷一致（pending_id + 目标字段全等）。
+- 前端视图不做：本轨只给后端 + 数据接口，客户端 UI 是另一侧的
+  工作，契约见各模块 docstring。
+
+## 4. 诚实边界
+
+- 哈希链是**篡改可发现**，不是防篡改：能写文件的人重算整条链
+  就能掩盖改动。真防篡改要外部锚定（远端日志/签名时间戳），
+  不在本轨。
+- 审计清洗是字段名黑名单 + `key=value` 模式脱敏，不是内容理解：
+  密钥若藏在自由文本字段里且不带 `token=`/`password=` 等标记，
+  清洗器看不出来。调用方仍须只传描述性字段（P3/P5 的口径）。
+- 活动视图的“正在做什么”来自计划登记与审计记录，不是实时
+  进程探针；VM 内真实执行状态以执行器为准。
+- 审批卡只做数据，不做签发：档位可选项由 Sentinel 决定（P5 口
+  径），本轨只呈现调用方传进来的档位列表。
+
+## 5. 决定记录
+
+- 导出选 JSON 不选 CSV：JSON 保留哈希链与嵌套结构，CSV 会丢
+  字段；任务简报允许二选一。
+- 审计持久化先用独立 JSONL 文件（`audit_trail.jsonl`，0600），
+  待 P7 状态库就绪后迁移，迁移接口是 `from_legacy_row()` 同款
+  转换（本文件行 → P7 记录）。**迁移已完成（round-12）**：
+  `StoreAuditTrail` 走宿主级 AppStateStore 的 `audit_trail` 表，
+  与 JSONL 版同一记录形状与哈希链；`migrate_jsonl_to_store()`
+  原样搬链（坏链拒绝、分叉拒绝、重跑幂等）；JSONL 版保留读旧
+  文件，新写一律走 Store 版。测试钉在
+  `cloud/tests/test_chv_muse_round12.py`。
+- project_id 强制：`list()`/`export()` 必须传 project_id，只返
+  回该项目记录；跨项目读取返回空，不抛错（与现有 `list_audit`
+  行为一致，不泄露“存在别的项目记录”这一事实）。
+
+## 6. 真机待验证清单（未做，排队在 round-11 之后）
+
+1. 审计轨迹（round-12 起走 StoreAuditTrail / SQLite，不再是
+   JSONL）在真实 VM 生命周期（wake/pause/resume/shutdown）
+   下的追加与 `verify()` 表现。
+2. 活动摘要与真实任务派发/完成事件的对应（正在做是否及时变
+   更、计划状态流转是否与 worker 终态一致）。
+3. 已批准权限清单与 P5 五档能力在 wake/同步路径下的真实表现
+   （签发→使用→过期→撤销全程）。
+4. 审批卡数据与 P5 对话外通道在真机上的端到端一致（卡上点的
+   接受/拒绝与通道答复同一 pending_id）。
+5. 审计库落盘权限（0600）与多进程追加（worker + host.py）
+   下的完整性（SQLite WAL + 30 秒 busy 超时）。

+（官方以 Meta security.muse.ai 2026-09-08 为准；第三方拆解只作参考，
+逆向细节不得写成官方架构）。Muse 浏览器安全要求一句话：真实最新的
+Chromium、位于虚拟化层之后；浏览器子代理只看到页面无障碍树快照、

+用户接管浏览器或凭证存储正在填表时，代理被暂停、完全不能行动；

+## 0. 与 P2 的关系（先说清，免得合入时糊涂）
+

+（只返无障碍树快照，`evaluate`/`content`/DevTools 一律拒绝）、
+`chv-guest/chv-broker.py`（单元外转发）、`chv-guest/chv-cell.py`、

+- `chv-guest/chv-cell.py`、`chv-guest/chv-broker.py`：P4 未改内容，
+  与 P2 版逐字节一致，合入无冲突。
+- `chv-guest/chv-browser.py`：P4 在 P2 版基础上重构（不再直连
+  Playwright，改走 CDP broker；见 §2），合入时直接取 P4 版。
+- `chv-guest/build.sh`、`chv-guest/buildinfo.py`：P4 版 = P2 版的步骤
+  + P4 新增步骤（CDP broker 服务、guard 模块、拦截名单、ask 队列目录），
+  合入时取并集。
+- `cloud/tests/test_chv_muse_p2.py`：P2 的测试文件本轨不拷、不改；
+  P4 的测试是独立的 `cloud/tests/test_chv_muse_p4.py`。P2 测试里
+  有一处与 P4 行为有关：`test_open_returns_a11y_snapshot_with_fake_playwright`
+  假定 `BrowserAgent` 直连 Playwright——合入后该测试须按 P4 的新结构改
+  （走假 CDP broker），见 §5；本轨不改它，留给集成者按本表执行。
+
+## 1. 现状 vs Muse
+
+| 项 | 现状（P2 已交付，代码为准） | Muse 目标 | 本轨做法 |
+|---|---|---|---|
+| 子代理看到什么 | `accessibility.snapshot()` 无障碍树（截断 200 节点/64KB）+ 标题/URL；`evaluate`/`content` 已拒 | 只见无障碍树快照，不见原始 DOM | 收紧到底：快照路径上所有回包与错误信息过 `sanitize_error`（去 HTML 标签、截断 200 字符、含尖括号即丢弃原文），任何响应字段不得含 `ws://`、DevTools 地址、原始 HTML；AST 测试钉住两个客机脚本里不存在脚本注入面 |
+| 页面内 JS | socket 层拒 `evaluate` 等操作，但 Playwright 直连在 `chv-browser.py` 进程内——代码里今天没调，不等于调不了 | 不能在页面上下文运行 JS，无脚本动词 | Chromium 的所有权移到单元外 CDP broker；broker 只调白名单调用（`goto`/`title`/`url`/`accessibility.snapshot`/`screenshot`/`close` + 只读监听 `on(request/download)`）；`evaluate`/`add_script_tag`/`add_init_script`/`expose_function`/`set_content`/`eval` 等一律不在代码里出现，AST 测试扫两个脚本的全部属性名 |
+| 浏览器进程内 exec | 无此操作 | 无浏览器进程内 exec | 同上：broker 与子代理的代码里不存在任何经浏览器执行命令的调用；`page.keyboard`/`mouse` 等交互调用也不在白名单内（本轨无点击/填表操作） |
+| DevTools | 未显式开 `--remote-debugging-port`，但 Playwright 直连默认持有 CDP 端点，且 `chv-browser.py` 进程内可及 | DevTools 被禁用；CDP 由单元外 broker 管理 | launch 参数白名单（见 §2），无 `--remote-debugging-port`、无 `devtools=True`；CDP 端点（ws 地址）绝不进任何响应；Chromium 由 `chv-cdp-broker`（单元外、用户 `chv-browser`）独家启动，子代理只经 broker socket 说话 |
+| CDP broker | 无（P2 是子代理直连 Playwright） | CDP 连接由单元外 broker 管理 | 新 `chv-guest/chv-cdp-broker.py`：单元外进程，Unix socket `/run/chv/cdp-broker.sock`，独家持有 Playwright/Chromium；`chv-browser.py` 改为 broker 的客户端 |
+| 接管/填表暂停 | 无此语义 | 用户接管或凭证注入填表时代理被暂停、完全不能行动 | 状态机 `active/paused` 落在 CDP broker（`pause`/`resume`/`status` 操作）；暂停时除 `ping`/`resume`/`status` 外一切操作拒绝；触发源：显式 `pause` 操作（供将来用户接管通道调用）、POST 表单提交被观测到时自动暂停、高风险下载命中时自动暂停；凭证注入填表联动是 P3 的 authd 注入点，本轨只留 `pause` 操作接口与接线设计 |
+| 高风险表单提交 | 无（P2 的 API 里根本没有点击/填表操作） | 支付/密码类表单提交前停下等审批 | 确定性规则（不冒充模型分类器）：`detect_form_risk` 扫无障碍树，密码/支付字段即标 `form_risk`；高风险表单在页时 `open` 导航即返回 `ask`（入待审批队列、执行停止）；观测到 POST 请求即自动暂停 + 入队。审批队列与 P3 的 `ApprovalQueue` 同语义（见 §4） |

+
+## 2. 改了什么（本轨交付物）
+
+- `chv-guest/chv_browser_guard.py`（新，纯标准库，无 Playwright）：
+  共享纯函数，两脚本共用：`validate_url`（P2 规则：只 http/https、
+  拒 localhost/私有地址字面量）、`check_blocklist`（读名单文件、
+  后缀匹配）、`truncate_a11y`（P2 的截断逻辑原样搬入）、
+  `sanitize_error`（错误信息去 HTML、截断 200 字符、凭据形
+  key=value 与 sk- 形 token 打码、含尖括号即丢弃原文）、
+  `detect_injection`（启发式模式表，中英文各 6 条，命中返回标签）、
+  `detect_form_risk`（无障碍树扫密码/支付字段）、`scan_download`
+  （一条可执行扩展名规则）、`enqueue_ask`/`list_asks`/`resolve_ask`
+  （文件型待审批队列，`/run/chv/ask-queue/`，一条 ask 一个 JSON 文件，
+  `pending/allowed/denied` 三态）、`LAUNCH_ARGS`（Chromium 启动参数
+  白名单）、`FORBIDDEN_PAGE_ATTRS`（禁用的 Playwright 调用名表）。
+- `chv-guest/chv-cdp-broker.py`（新，标准库 + playwright 懒加载）：
+  单元外 CDP broker，用户 `chv-browser`，Unix socket
+  `/run/chv/cdp-broker.sock`。独家 `chromium.launch(headless=True,
+  args=LAUNCH_ARGS)`；操作 `open/snapshot/screenshot/close/ping/
+  pause/resume/status/list_asks/resolve_ask`；导航前 `validate_url` +
+  `check_blocklist`；快照恒带 `untrusted_input: true`，命中注入模式带
+  `injection_flags`；表单风险与 POST 观测、下载命中走 ask 队列 +
+  自动暂停；所有回包与日志过 `sanitize_error`，绝不返回 ws 端点。
+- `chv-guest/chv-browser.py`（P2 版基础上改）：不再直连 Playwright，
+  改为 CDP broker 的客户端（每请求一连接，Unix socket JSON 行）；
+  保留 `validate_url`/`truncate_a11y` 二次校验（纵深防御）、
+  `FORBIDDEN_OPS`（扩到 `click/fill/type/press/hover/select/check/
+  evaluate/content/devtools/js/route/expose/add_init_script/
+  add_script_tag/set_content/eval`）、暂停镜像状态（broker 暂停时
+  本层同样拒绝）；`playwright_factory` 参数删除（不再需要）。
+- `chv-guest/browser-blocklist.txt`（新）：静态拦截名单。格式一行一个
+  条目（域名或 `.后缀`）；来源：随镜像发布的静态文件，首版只含 RFC 2606
+  保留 `.test` 域的格式示例与自测条目（`malware.test`、
+  `.phishing.test`），**不编造真实恶意域名**；生产名单由运维在构建时
+  用公开情报源（如 URLhaus / Google Safe Browsing 导出）的域名替换
+  本文件后重建镜像；更新机制 = 换文件 + 重建镜像，无在线更新（在线
+  更新列为后续，不冒充已做）。
+- `chv-guest/build.sh`：P2 的步骤原样保留，加 P4 步骤：拷入
+  `chv-cdp-broker.py`、`chv_browser_guard.py`、`browser-blocklist.txt`
+  （缺一即失败）；装 `chv-cdp-broker.service`（用户 `chv-browser`）
+  并 enable；tmpfiles.d 加 `/run/chv/ask-queue`（0750
+  `chv-browser:chv-browser`）。
+- `chv-guest/buildinfo.py`：P2 的内容项原样保留，加 `chv-cdp-broker`、
+  `chv-browser-guard`、`browser-blocklist`。
+- `cloud/tests/test_chv_muse_p4.py`（新）：见 §5。
+- `docs/chv-production-readiness.md`：补 P4 一节，旧定案不删、只追加。
+
+## 3. 诚实边界（本轮不宣称的东西）
+
+1. **分类器是确定性规则，不是模型分类器**：注入启发式、表单风险、
+   下载规则都是字面规则，有漏报也有误报；它只做“标注 + 拦截高危”，
+   不做语义判断。Muse 的浏览器分类器家族是模型 + 规则，本轨只做了
+   规则那半。
+2. **a11y-tree-only 的边界与 P2 相同**：单元内进程仍可用 curl/Python
+   标准库直接发 HTTP 取页面原文——那不是“浏览器 DOM 访问”，但也不是
+   无障碍树；出口只走浏览器子代理是 P3 Sentinel 的事，本轨不冒充已封死。
+3. **暂停的触发源不完整**：显式 `pause` 操作与自动暂停（POST 观测、
+   下载命中）已实现并测试；“用户在浏览器里接管”与“凭证注入填表”这两
+   个真实触发源还没有对端——前者要等真人浏览器联动（控制面），后者是
+   P3 的 authd 注入点。接口与状态机已留好，联动列为真机验证。
+4. **ask 队列的审批人不在本轨**：队列是文件型的待审批记录（与 P3
+   `ApprovalQueue` 同语义，见 §4），`resolve_ask` 接受外部写回的
+   `allow/deny`；但谁来审批（人、还是 Sentinel 策略）不在本轨决定，
+   P5 做审批 UI 在对话外之后再接。
+5. **拦截名单是静态的**：首版只有格式示例与自测条目，生产条目须由运维
+   在构建时填入；名单的覆盖率、误拦率本轮无数据，不宣称“已拦截恶意站”。
+6. **性能数字全是待验证目标**：CDP broker 多一跳的延迟、快照标注后
+   的 token 占用、拦截名单加载耗时——本轮无真机验证，一律记入 §5 清单，
+   不在代码/文档里写成已测得。
+7. **Chromium 启动参数以 Playwright 1.65 + headless-shell 为准**：
+   白名单参数均为真实 Chromium 开关（`--disable-gpu`、`--no-first-run`、
+   `--disable-dev-shm-usage`、`--disable-extensions`、
+   `--disable-background-networking`、`--disable-sync`、
+   `--disable-translate`、`--mute-audio`）；`--no-sandbox` 刻意不在
+   白名单内（浏览器以非 root 的 `chv-browser` 身份跑，不应再降级沙箱；
+   若客机内启动失败，属真机验证项，不在本轮改参数凑合）。
+
+## 4. 与 P3/P5/P6 的接口（不碰对方文件，只定契约）
+
+- **P4 → P3（ask 队列）**：ask 记录格式与 P3 `ApprovalQueue` 同语义：
+  `{ask_id, kind, url, detail, status: pending/allowed/denied,
+  created_at}`；`kind` 本轨有三类：`form_submit`（高风险表单时导航）、
+  `form_submit_observed`（观测到 POST）、`download_blocked`（下载命中）。
+  宿主侧 Sentinel 读到 `pending` 的 ask 后按 P3 的 allow/deny/ask 决策，
+  经 `resolve_ask` 写回；`allowed` 后 broker 解除暂停（`form_submit`
+  类还需调用方重发原操作，本轨不自动续跑）。队列的宿主侧读取路径是
+  `host.py` 经 SSH 读 `/run/chv/ask-queue/`（接线设计，P6 或控制面实现，
+  本轨只留 `list_asks` 操作与文件格式）。
+- **P4 → P5（审批 UI）**：`resolve_ask` 的调用方是 P5 的对话外审批 UI；
+  在此之前 ask 只记录、不自动放行（`allowed` 缺席即一直停）。
+- **P4 → P6（确定性安全检查层）**：`detect_injection` 的
+  `untrusted_input: true` 标注是 P6 的外部数据标注的浏览器侧来源；
+  P6 复用本轨的模式表时以本文件为准，不另起一份。
+- **P2 → P4（已兑现）**：P2 的 `BrowserAgent` 直连 Playwright 的结构
+  已被本轨改成 broker 客户端；P2 测试里假定直连的那一处（见 §0）由
+  集成者按本表改，不在本轨动 P2 的测试文件。
+
+## 5. 真机待验证清单（round 12，测试机空闲后）
+
+- lite 验收照旧：qcow2 ≤1GB、冷启动到 SSH、codex 版本、headless-shell
+  例、Gitea 双向同步。
+- 浏览器对齐验收（新增）：
+  1. 客机内 `chv-cdp-broker` 进程以 `chv-browser` 身份跑，Chromium
+     正常启动（`--no-sandbox` 未加时仍能起）；启动参数里无
+     `--remote-debugging-port`。
+  2. 经 broker `browser open https://example.com` 返回标题 Example
+     Domain 与无障碍树，响应里无 `ws://`、无 DevTools 地址、无 HTML。
+  3. 单元内进程连不上 CDP 端点（broker 的 socket 只在单元外，单元内
+     无 Chromium 可连；`python3 -c "import playwright"` 在单元内仍失败）。
+  4. 含密码字段的测试页快照带 `form_risk: password`；此时 `open` 导航
+     返回 `ask`、页面不跳转；`resolve_ask allow` 后重发导航成功。
+  5. 注入文本测试页快照带 `untrusted: true` + `injection_flags`。
+  6. 命中拦截名单的域名导航被拒（先用 `.test` 自测条目，再换生产名单复测）。
+  7. 触发下载 `.exe` 的测试页：下载被取消、代理暂停、`ask` 入队。
+  8. `pause` 后 `open/snapshot` 被拒、`ping` 仍通；`resume` 后恢复。
+  9. 性能记录（只记录、不设门）：broker 多一跳的快照往返、拦截名单加载耗时。
+- 集成者须改的一处：P2 测试 `test_open_returns_a11y_snapshot_with_fake_playwright`
+  在合入 P4 后失效（`BrowserAgent` 不再直连 Playwright），改为走假
+  CDP broker（与 P4 测试的 `FakeCdpBroker` 同款），断言不变。

+依据：`~/workspace/research_notes/meta-muse-ai-architecture-20261101-0755/report.md`
+（官方以 Meta security.muse.ai 2026-09-08 为准；第三方拆解只作参考，
+逆向细节不得写成官方架构）。Muse 官方 Sentinel 要求：Sentinel 是
+连接器动作与全部网络出口的唯一权限机构；网络出口审批在 L4 与 L7
+评估主机名、解析后与最终目的 IP、端口、协议、HTTP 方法、路径、
+解码后的实际请求，并有 SSRF 防护；污点出口——每个工具执行进程
+初始干净，读取用户数据后变“污点”，干净且符合窄范围自动放行策略
+并通过出站 URL 其他检查的请求可免打扰放行，污点或不可验证进程
+失去自动放行、回到正常审批流，实现用 eBPF cgroup 程序做网络拦截
+与进程归因、及挂在 LSM hook 上的 eBPF 程序做污点传播；审批是
+严格能力，绑定到特定连接器/目的地与用例，支持一次性、会话级、
+任务级、时限级、永久级授权，Sentinel 决定向用户呈现哪几种授权
+类型，并确保后续调用与授权范围精确匹配；审批 UI 不在对话内，
+Sentinel 直接向客户端发审批请求、用户答复直接回 Sentinel；默认
+策略只读/先前已允许/明显低风险动作可不打扰通过。
+
+本轨范围只限 P5：Sentinel 纵深。起点是 P3（分支 feat-chv-muse-p3

+
+## 0. 起点（P3 已做的，本轨不重写）
+
+P3 交付的 `cloud/chv/sentinel.py`（决策层，纯函数 + 内存态队列，
+标准库）：`SentinelPolicy.evaluate()`（allow/deny/ask；L4 解析后
+IP/端口/协议 + L7 主机/方法/路径；SSRF 挡截；未知连接器/scheme/
+端口/路径越界 → deny；不在白名单 → ask）；严格能力 `Capability`
+（绑定 {连接器, 主机, 方法, 路径, 有效期, 次数}，默认单次 + 300 秒
+TTL，`matches()`/`use()`）；`ApprovalQueue`（ask 记入内存态待审批，
+resolve 只标记不放行）。两个接线点：wake 时 Gitea 出口预审、
+authd 放凭证前评估。P3 明确列为后续的本轨三项：eBPF 污点传播、
+审批 UI 不在对话内（只留队列）、能力只有一次性一档（官方有五档）。
+
+## 1. 现状 vs Muse
+
+| 项 | 现状（实测/代码为准） | Muse 目标 | 本轨做法 |
+|---|---|---|---|
+| 污点出口 | 无。Sentinel 是决策层，不拦截客内流量；客内直连靠 Tinyproxy 白名单 + 宿主防火墙兜底；进程“读了用户数据”这个事实没有任何地方记录 | 每个工具执行进程初始干净，读用户数据后变污点；干净 + 窄范围自动放行策略 + 出站 URL 检查通过 → 免打扰放行；污点或不可验证进程失去自动放行、回正常审批流；eBPF cgroup 程序做网络拦截与进程归因、LSM hook 做污点传播 | `cloud/chv/taint.py`（污点追踪器：进程干净/污点两态、读用户数据事件 → 污点、子进程继承、审计）+ `cloud/chv/ebpf_taint.py`（eBPF 程序源码 + 加载器 + 能力探测 + 降级）；宿主侧先做可测试的最小闭环：策略引擎（纯标准库、可单测）+ eBPF 加载层（可探测、失败时明确降级、不冒充已加载）。客内 eBPF 加载可行性实测后写进 §3，不行就写清阻塞点 |
+| 严格能力分级 | 只有一档：单次 + 300 秒 TTL（P3 默认）。无会话/任务/时限/永久的概念；无“用例”维度（只绑连接器/主机/方法/路径） | 严格能力绑定到特定连接器/目的地与用例，支持一次性、会话级、任务级、时限级、永久级授权；Sentinel 决定向用户呈现哪几种授权类型；后续调用与授权范围精确匹配 | `cloud/chv/capabilities.py`：五档全实现（one-shot / session / task / timed / permanent），能力绑定 {连接器, 目的地, 用例} 三元组 + 方法/路径/次数/过期；`matches()` 精确匹配检查（超范围即 deny + 审计）；每档的签发条件与上限写进规则表（永久级默认不签发，须显式策略开启 + 审计） |
+| 审批 UI 在对话外 | 只有 `ApprovalQueue` 内存态队列：ask 记入、resolve 只标记；没有任何请求/答复通道；对话内容伪造审批的风险只在文档里写了约束，无机制防 | Sentinel 直接向客户端发审批请求，弹窗在客户端 UI 内，答复直接回 Sentinel；目的：防对话内容伪造审批 | `cloud/chv/approval_channel.py`：独立审批通道（请求/答复协议、nonce + 有效期 + 签名/HMAC 校验，答复须与请求绑定；对话内容里出现的“批准”字样一律无效）；通道两端接口 + 契约文档；客户端 UI 呈现是另一侧的事，留好接口、不冒充已做 UI |
+| 默认策略 | 只有 default-deny + 白名单/拒绝名单 + L7 规则；无“只读/已允许/低风险不打扰”的分层规则，无可调谨慎度 | 只读、先前已允许、明显低风险动作可不打扰通过；用户可把默认调得更谨慎或更宽松 | `cloud/chv/policy.py`：默认策略规则表（只读方法 GET/HEAD + 已允许主机/路径 + 低风险判定）+ 谨慎度三档（default / cautious / permissive，默认 default；permissive 不放行写操作与敏感路径）；规则变化（档位切换、规则增删）全部审计 |
+| 审计 | P3 的 `_emit` 契约：`sentinel_egress_allow/deny/ask`，detail 只含连接器/主机/路径/verdict/原因，不含凭证值 | 审计轨迹展示已做与计划做的事 | 沿用契约，新增事件：`sentinel_taint_marked`（进程变污点）、`sentinel_auto_allow`（干净进程自动放行）、`sentinel_capability_denied`（超范围/过期/超次）、`sentinel_approval_requested/answered`（通道审批）、`sentinel_policy_changed`（规则/档位变化）；detail 只含进程/连接器/目标/ verdict/原因，绝不含用户数据内容与凭证值 |
+
+## 2. 改了什么（本轨交付物，已做完）
+
+- `cloud/chv/taint.py`（新，标准库）：污点追踪器——进程注册（pid/cgroup/连接器/用例）、干净 → 污点（`mark_tainted(pid, source)`，source 只存分类）、子进程继承污点、污点不可清除（无任何清除入口，只随进程退出消失）、`is_tainted`、`auto_allow_eligible`（污点与未知 pid 一律 False）、审计（事件名 + pid + 原因，无内容、无凭证值）。
+- `cloud/chv/ebpf_taint.py`（新，标准库）：eBPF 程序源码常量（`cgroup_skb/egress` 拦截 + `taint_map` HASH 进程归因 map + RINGBUF 事件上报；`lsm/file_open` 污点传播骨架，共用 pin 住的 map，路径表由用户态下发、不读文件内容）+ `EbpfTaintLoader`（能力探测：内核版本、/sys/fs/bpf 是否存在可写、CapEff bit 39 CAP_BPF / bit 21 CAP_SYS_ADMIN、bpftool/clang/llvm-objdump；状态 loaded/degraded/blocked + 原因；加载失败一律降级为 `policy_engine_proxy_hooks`，`try_load` 须 bpftool 加载 + pin 在位双重确认才报 loaded）。
+- `cloud/chv/capabilities.py`（新，标准库）：五档严格能力，继承 P3 `Capability`——one-shot（单次/300 秒）、session（会话 id 绑定，默认 3600 秒）、task（任务 id 绑定，默认 3600 秒）、timed（须显式 ttl）、permanent（默认拒绝，须显式 `allow_permanent=True`）；绑定 {连接器, 主机, 用例} 三元组 + 方法/路径/次数/过期；`matches(request, now, scope)` 精确匹配（`scope` 须按关键字传，`now` 仍占第二位置参数，与 P3 旧口径一致）；`use()`/`revoke()`；签发/使用/过期/超次/撤销全审计。
+- `cloud/chv/policy.py`（新，标准库）：默认策略规则表 + 谨慎度三档（default：已允许主机 + 路径前缀；cautious：精确主机 + 精确路径；permissive：只读 + 非敏感即候选，不必先前已允许）；三档共性：写操作与敏感路径（/admin、/settings、/login、token 相关）永远不自动放行，污点进程一律不自动放行；`set_caution`/`add_rule`/`remove_rule` 每次变化记 `sentinel_policy_changed` 审计。
+- `cloud/chv/approval_channel.py`（新，标准库）：独立审批通道——`ApprovalRequest.payload()`（pending_id + nonce + 目标描述 + 原因 + 过期，默认 15 分钟，无凭证值与用户数据内容）；`Answer`（pending_id + nonce + verdict + 过期 + HMAC-SHA256 签名）；`verify_answer`（pending 存在 + nonce 对上 + 未过期 + 签名对上 + verdict 合法，五项缺一即 False）；`resolve_via_channel`（校验通过才调 `ApprovalQueue.resolve`，成功即消费登记、答复只能用一次）；密钥由调用方保管，通道不保存密钥、不进载荷、不进日志。
+- 接线（`cloud/chv/sentinel.py`，唯一改动的已有文件）：`evaluate()` 新增可选接线参数（`taint_tracker`/`pid`/`default_policy`/`tier`/`scope`），不传时行为与 P3 完全一致；安全检查（步骤 1–6）抽成 `_safety_verdict`；新增自动放行步骤（干净进程 + 只读 + 已允许 + 低风险 + 过 L7 路径规则 → allow + 按档位签发能力，原因 `policy_auto_allow`；污点进程一律不放行、回到正常审批流）；档位签发失败回落单次（更严格，原因 `capability_tier_fallback`，不抛错）；`Decision` 加 `tainted` 标记（审计里仅当 True 时出现）；`Capability` 基类的 `max_uses`/`uses_left`/`expires_at` 放宽为 Optional（None = 不限，供五档用；单次档仍是 int，行为不变）。
+- `cloud/tests/test_chv_muse_p5_taint.py`（18 项）、`test_chv_muse_p5_capabilities.py`（21 项）、`test_chv_muse_p5_approval.py`（11 项）、`test_chv_muse_p5_wiring.py`（11 项，接线：自动放行/污点回流/三档策略/档位签发与回落/通道端到端/对话伪造无效）。新测试共 61 项。
+
+## 3. 诚实边界（本轮不宣称的东西）
+
+1. **eBPF 加载在本机实测不行，证据确凿（不是推断）**：本 Muse VM 实测（2026-11-07，ctypes 直接调 `bpf()`，syscall 号 321）：最小合法程序 `BPF_PROG_LOAD`（SOCKET_FILTER，`r0=0; exit`，GPL）返回 **-1，errno 1 EPERM，verifier 日志为空**；`BPF_MAP_CREATE` 同样 -1 EPERM。空 verifier 日志说明在 verifier 之前就被挡；`/proc/self/status` 显示 `Seccomp: 2`（filter 模式）——**`bpf()` 系统调用本身被 seccomp 挡，能力位在位不等于系统调用放行**。其余探测：内核 7.0.0-43-generic；CapEff `000001fffff7cfff` 解码 CAP_BPF bit 39 = 在位、CAP_SYS_ADMIN bit 21 = 在位；`/usr/include/linux/bpf.h` 在位，gcc 在位；但**无 `/sys/fs/bpf`**（`/sys/fs` 下 0 处 bpf 挂载）、**无 bpftool/clang/llvm-objdump**。加载器 `probe()` 因此报 `blocked`（blockers 含 `bpffs_missing`、`tool_missing:bpftool/clang/llvm-objdump`）。本轨交付“策略引擎 + 加载器 + 降级”与本实测结论，不把“写了 eBPF 程序源码”等同于“eBPF 已在拦截流量”。客内（WSL 测试机 VM 里）加载可行性须真机验证，见 §4；教训：真机验证须先确认客内容器/VM 的 seccomp 配置是否放行 `bpf()`，只看 CapEff 会误判。
+2. **污点追踪的“读用户数据”事件靠调用方上报**：纯用户态追踪器不知道进程真读了什么文件——污点标记的输入是工具执行层在读用户数据前调用 `mark_tainted()`（或 LSM hook 回调，eBPF 通了才有真事件）。没接 LSM hook 之前，漏报是可能的；本轨不宣称“所有读用户数据的行为都被捕获”。
+3. **审批通道不是客户端 UI**：本轨做请求/答复协议与校验，不做弹窗 UI。没有客户端接入之前，ask 仍须人工在通道外处理；不得写成“审批弹窗已上线”。
+4. **永久级能力默认不签发**：按 Muse 口径 Sentinel 决定呈现哪几种授权类型；本轨永久级默认关闭，须显式策略开启 + 审计；开启后仍绑定三元组与审计，永不过期不等于无审计。
+5. **无真机验证**：本轮全部是代码 + 本地单测。真机待验证清单见 §4，测试机须排队（第三棒 V-1～V-9 与 round-11 之后）。
+
+## 4. 真机待验证清单（测试机空闲后，round-11 之后排队）
+
+1. eBPF 程序在 WSL 测试机客内真加载：加载是否成功、cgroup 拦截是否真拦住直连、进程归因 map 是否对得上 pid、LSM hook 是否真收到读事件。
+2. 污点进程在真机上的出口表现：干净进程自动放行、读用户数据后出口回审批流、ask 停止执行。
+3. 五档能力在真机 wake/同步路径下的表现：会话/任务级能力跨多次调用仍有效、过期/超次即拒。
+4. 审批通道端到端：ask 发出 → 通道外答复 → 放行/拒绝生效；对话内容伪造答复在真机上无效。
+5. 默认策略三档在真机上的表现：cautious 档是否多拦、permissive 档是否仍挡写操作与敏感路径。

+| worker 身份与凭证白名单 | 无 worker 概念，无白名单。`chv-sync` 直接读落盘的 `.git-credentials`（旧路径）或走 P3 helper（新路径），调用方改参数就能让它对任意仓库跑 git | 每个 worker 由 cgroup 标识、有明确凭证白名单（改参数也索取不到别的凭证） | worker 注册表只认一个 worker：`gitea`，凭证白名单只含 `GITEA_TOKEN`，操作只含 pull/push/status/ping，仓库只限 `~/workspace` 下。白名单三处 enforce：① 客户端（`PrivsepClient`）发请求前校验，越权请求不出门；② worker 服务端再校验一次（不信任客户端）；③ 凭证获取本身不经过 worker——git 经 P3 的 credential helper 向 authd 按次取凭证，authd 按 {连接器, 主机, 仓库, 操作} 绑定放行，worker 改参数也拿不到别的凭证。worker 进程本身绝不持有 token 值（argv/env/日志/审计里都没有） |
+| worker 的网络出口 | `chv-sync` 的 git 直连 Gitea；出口只靠 Tinyproxy 白名单 + 宿主防火墙（第三棒落地中），无每动作审批 | Sentinel 评估每个动作与全部网络出口 | worker 的 git 只配 P3 helper + 只连配置的 Gitea 远端；每次取凭证前 authd 已先过 Sentinel 评估（P3 机制，本轨不重复造）；worker 的 systemd 单元再叠加 `RestrictAddressFamilies` 与网络命名空间收紧。网络层强制（eBPF 拦截）是 P5 的范围，本轨不宣称 |
+| 外部数据进模型上下文 | 无标注。Gitea 拉回的提交信息、文件名、diff 内容经 `chv-sync` 输出原样回到 agent 回合，codex 自己拼上下文，我们这边不区分“用户写的”与“远端拉回的” | Harness 层：外部数据进入模型上下文时标注为“不受信任输入” | `cloud/chv/safety.py`：`UntrustedData` 携带来源标记（`source`，如 `gitea:<repo>`）随数据走；worker 的 git 输出在返回前先过扫描 + 打上来源标记；`PrivsepClient` 把标记带回调用方。注意诚实边界：codex 在客内自己拼上下文，我们的标注能保证的是“经我们这条连接器链路回来的数据都带标记”，不是“codex 一定会读标记”——后者须 codex 侧配合，不在本轨 |
+| 提示注入检测 | 无 | 独立分类器层：多组提示注入检测分类器并行，覆盖经文件与工具调用进入上下文的全部外部数据 | 确定性规则版 `InjectionScanner`（不是模型分类器，不冒充）：指令性文本规则（中英）、命令/URL 注入模式、可疑拼接模式；分级 `block`/`flag`/`allow`。`block` 只给高置信模式（shell 执行链、直接指令覆盖）；`flag` 给中置信（指令性文本、可疑 URL），命中即标记复核、不自动执行后续写操作；`allow` 其余。规则覆盖边界单列在 §3.3 |
+| 请求/响应审计（hatch-safety） | 执行器 `_emit` 只审 VM 生命周期事件（VM 名/路径/URL/kind，不含 key 值）；进出模型推理的请求/响应无审计 | hatch-safety 检查进出核心模型推理的请求/响应 | `safety.audit_inference_request/response`：在执行器派发边界（`_run_guest`，任务 → 客内 codex；结果回）记审计——只记任务 id、kind、内容指纹（SHA-256 前 16 位）、长度、扫描 verdict；密钥与 token 值绝不进审计（先过 `redact_secrets` 再记，审计失败 best-effort、不中断任务，沿用 `_emit` 既定语义） |
+| 与 P3 的接线 | P3 已做完（a90cf78）：authd 替身凭证 + Sentinel 最小审批 | privsep worker 的凭证只走 authd 替身；worker 出口只走 Sentinel 审批 | worker 的 git 一律配 `-c credential.helper=/usr/local/bin/git-credential-chv-authd -c credential.useHttpPath=true`（P3 的 helper 路径与 P3 修过的 path 坑），不用 `.git-credentials`；helper 缺失时 worker 直接拒绝（fail-closed），不回落读 token。Sentinel 评估发生在 authd 放凭证前（P3 机制），worker 不另造决策器。本轨不 import P3 的模块（基线 06c3e17 里没有 P3 代码）：接线走已定的文件/socket 协议，合入时由集成轨接通；本轨测试用替身（fake）实现同一协议 |
+
+## 2. 改了什么（本轨交付物）
+
+- `cloud/chv/privsep.py`（新，叶子模块，标准库）：worker 注册表
+  （本期只 `gitea`）+ 类型化请求/响应（`WorkerRequest` /
+  `WorkerResponse`，JSON 行，≤64KB）+ `PrivsepClient`（Unix socket
+  客户端：超时、worker 崩溃 → 类型化失败、响应校验、返回前过安全
+  扫描）+ 客户端白名单校验（越权请求不出门）+ cgroup 标识读取
+  （`/proc/<pid>/cgroup`，审计用）。
+- `cloud/chv/safety.py`（新，叶子模块，标准库）：`UntrustedData`
+  来源标记 + `InjectionScanner`（规则版，中英指令模式、命令/URL
+  注入模式、可疑拼接，分级 block/flag/allow）+ `redact_secrets`
+  （token/key/口令模式脱敏）+ `audit_inference_request/response`
+  （只记指纹与 verdict，不记值；失败 best-effort）。
+- `chv-guest/chv-gitea-worker.py`（新，标准库守护进程）：Unix socket
+  `/run/chv-gitea/worker.sock`（0700 目录、0600 socket）；SO_PEERCRED
+  只放行 root（broker 走 root 连）；操作白名单 pull/push/status/
+  ping；仓库只限 `~/workspace` 下（realpath + commonpath）；git 以
+  chv 身份跑（`runuser -u chv`，文件归属不变），argv 里只配
+  credential helper、绝无 token；输出先过 `safety` 扫描 + 来源标记
+  再返回；超时 300 秒；异常只断本连接。
+- `chv-guest/chv-gitea-worker.service`（新）：systemd 单元（root 运行，
+  单元外；`ProtectSystem=strict`、`PrivateTmp`、`NoNewPrivileges`、
+  `CapabilityBoundingSet=` 空、`RestrictAddressFamilies=AF_UNIX AF_INET
+  AF_INET6`、`SystemCallFilter=@system-service`、读写路径只限
+  `/home/chv/workspace` 与 `/run/chv-gitea`）。
+- `chv-guest/chv-sync-worker-client.py`（新，标准库薄客户端）：
+  `chv-sync pull/push/status` 在 worker socket 存在时改走 worker
+  （发类型化请求、原样回显 worker 的 stdout/stderr、按 worker 的
+  returncode 退出）；socket 不存在时走旧的直接路径 + stderr 警告
+  （过渡兼容，见诚实边界第 4 条）。
+- `chv-guest/chv-sync.sh`：pull/push/status 三处改走上述客户端
+  （有 socket 时）；boot 不动（cloud-init 时的一次性 clone，仍按
+  P3 后的 helper 路径走）。
+- `cloud/chv/executor.py`：`_run_guest` 前后加推理边界审计钩子
+  （best-effort，不改结果、不中断任务）。
+- `cloud/tests/test_chv_muse_p6.py`（新）：见 §3 的覆盖清单。
+- 镜像集成（只留接入说明，不改 `chv-guest/build.sh`，与 P2/P3 同款
+  规矩，合并时由集成轨带进镜像）：
+  `--copy-in chv-guest/chv-gitea-worker.py:/usr/local/bin/`、
+  `--copy-in chv-guest/chv-sync-worker-client.py:/usr/local/bin/`、
+  `--copy-in chv-guest/chv-gitea-worker.service:/etc/systemd/system/`、
+  `--copy-in cloud/chv/privsep.py:/usr/local/lib/chv-gitea/cloud/chv/`、
+  `--copy-in cloud/chv/safety.py:/usr/local/lib/chv-gitea/cloud/chv/`、
+  `--copy-in cloud/__init__.py:/usr/local/lib/chv-gitea/cloud/`、
+  `--copy-in cloud/chv/__init__.py:/usr/local/lib/chv-gitea/cloud/chv/`、
+  `--run-command 'chmod +x /usr/local/bin/chv-gitea-worker /usr/local/bin/chv-sync-worker-client'`、
+  `--run-command 'systemctl enable chv-gitea-worker || true'`、
+  `99-chv-sync.cfg` 的 runcmd 在 `chv-sync boot` 之前加
+  `systemctl start chv-gitea-worker || true`。
+  另：worker 依赖 P3 的 helper（`/usr/local/bin/git-credential-chv-authd`
+  + authd socket `/run/chv-authd/authd.sock`），P3 的接入说明里的
+  copy-in 须一并落地，否则 worker 的 git 拿不到凭证、直接拒绝。
+
+## 3. 测试覆盖与诚实边界
+
+### 3.1 测试覆盖（`cloud/tests/test_chv_muse_p6.py`，全覆盖以下每一项）
+
+- privsep 协议：未知操作/未知连接器/仓库越界（`..`、workspace 外）
+  被拒；响应格式不对被拒；超时与 worker 崩溃（socket 半路关闭）
+  → 类型化失败 `WorkerRefusal`（不是裸 socket 异常、不拖垮调用方）。
+- 白名单：客户端越权请求（未知操作、未知连接器）不出门；服务端
+  再拒一次；worker 的 git argv 里只有 helper 配置、绝无 token 值。
+- worker 真 socket 回路：pull/push/status/ping 全通（假 git runner，
+  不跑真 git、不联网）；git 输出先扫描 + 打来源标记再返回。
+- 安全检查层：每条规则至少一个 block 用例、一个 flag 用例、一个
+  allow 用例（含中英）；真实 git 输出样式（commit 信息、URL、正常
+  英文）不误报；审计记录里扫不到任何测试密钥值；脱敏覆盖全部密钥
+  模式；`check_context_input` 的 block 即阻断、flag 即标记复核。
+- 推理边界审计：请求/响应审计只含指纹与 verdict；审计回调失败不
+  中断任务。
+
+### 3.2 架构测试约束
+
+新模块须过 `test_no_chv_function_over_50_lines`（函数 ≤50 行）与
+`test_public_api_fully_annotated_and_no_any`（公共 API 全注解、无 Any）。
+
+### 3.3 确定性检查层能拦什么、不能拦什么（单列）
+
+能拦：字面指令覆盖（中英常见写法）、shell 执行链（`curl|sh`、
+`$(...)`、反引号命令替换、`;` 拼接危险命令）、可疑 URL（非 https、
+IP 字面量、userinfo 含口令、`data:`/`javascript:`）、把指令藏在
+分隔线后的可疑拼接。不能拦：改写过的指令（同义词替换、拆字、编码、
+Base64、零宽字符）、藏在图片/附件/二进制里的指令、需要理解上下文
+才能判定的社会工程式诱导、模型自身的幻觉与误读——这些要模型分类器
+（hatch-safety 同款）才有机会拦，规则版拦不住，不得宣称已覆盖。
+规则是确定性的：同一输入永远同一 verdict，可复现、可测试；误报率
+靠 allow 用例钉住，新增规则须先补用例。
+
+### 3.4 诚实边界（本轮不宣称的东西）
+
+1. **本轨不 import P3 的模块**：基线 06c3e17 里没有 P3 的 authd/
+   sentinel 代码，本轨的接线走文件/socket 协议（helper 路径、
+   authd socket 路径、Sentinel 评估发生在 authd 放凭证前）。本轨
+   测试用替身实现同一协议；与 P3 代码的真正接通发生在合入时，
+   须由集成轨跑通 worker→helper→authd→git 的全链路。
+   **已接通（round-12，本地部分）**：`cloud/tests/
+   test_chv_muse_round12.py`（WorkerProtocolTest）用真
+   PrivsepClient + 真 worker server + 真 git status 跑通，worker
+   的 git argv 含真实 P3 helper 与 useHttpPath、argv/env/审计
+   均不含 token；runuser 包装与 HTTP 拉取（需真实 gitea.tose.top
+   + Sentinel 放行）留给真机轨。
+2. **worker 跑在客内 root**：worker 守护进程以 root 身份跑在单元外
+   （与 P3 authd 同款选择），git 子进程再以 chv 身份跑。root worker
+   本身不受单元隔离保护——它的隔离来自 systemd 沙箱 + socket 白名单
+   + 不持凭证；客内 root 万能仍是 P2 的边界，不是本轨能修的。
+3. **网络层强制不是本轨**：worker 的出口收紧靠 Sentinel 评估
+   （authd 放凭证前）+ 只配 helper 的 git + systemd 沙箱；eBPF
+   cgroup 拦截 + LSM 污点传播是 P5 的范围。不得把本轨写成“出口已
+   全部经 Sentinel 强制”。
+4. **过渡兼容留了旧路径**：worker socket 不存在时 `chv-sync`
+   pull/push/status 仍走旧的直接路径（只多一句 stderr 警告），为
+   的是旧镜像不被一次改断。旧镜像退役后应删掉该回落，改为无 worker
+   即 fail-closed；删除前不得声称“旧路径已关闭”。
+5. **无真机验证**：本轮全部是代码 + 本地单测（含 worker 真 socket
+   回路 + 假 git runner）。真机待验证清单见 §4。
+
+## 4. 真机待验证清单（等测试机空闲，排队在 round-11 之后）
+
+- worker 在 lite12 镜像里的启动时序（须在 broker/`chv-sync` 调用
+  之前就绪；与 P3 authd 的启动顺序关系）。
+- worker 的 systemd 沙箱在真机上生效（`systemctl status`、cgroup
+  路径、受限调用被挡的表现）。
+- broker → worker → helper → authd → git 全链路在真机上跑通
+  pull/push（真 Gitea、真 token 替身）。
+- worker 崩溃后 agent 侧只收到类型化失败、任务不炸（杀 worker
+  进程复现）。
+- 安全扫描在真机 git 输出上的误报率抽查（真实 commit 信息样本）。

+# 对齐 Muse P7 差距表：状态与记忆分离
+
+依据：`~/workspace/research_notes/meta-muse-ai-architecture-20261101-0755/report.md`
+（Meta 官方 security.muse.ai / 设计文 / 新闻室 2026-09-08 为准；第三方拆解只作参考，
+逆向细节不得写成官方架构）。基线：`06c3e17`。
+
+## §1 Muse 官方要求（本轨范围）
+
+| # | 官方要求 | 来源 |
+|---|---|---|
+| 1 | Postgres 存持久应用状态，与运行时单元、凭证存储分离 | 安全文 §2.1 架构图 + §3.4 |
+| 2 | 凭证与 OAuth token 存于用户 VM 内、不在 Meta 集中基础设施；VM 是用户放入 Muse 的一切内容的系统记录 | 安全文 §3.3 |
+| 3 | 用户可检查、编辑、下载 VM 内所有文件，包括 Muse 关于用户的记忆 | 安全文 §3.3 |
+| 4 | 记忆跨对话持续存在，用户可回指以往讨论过的内容；记忆文件可直接阅读与编辑 | 设计文 + 帮助中心 §2.4 |
+| 5 | 用户可随时让 Muse“忘记”它学到的特定内容 | 新闻室 §2.4 |
+| 6 | VM 数据持续备份以便恢复 | 安全文 §3.3 |
+
+官方**没有**披露：Postgres 表结构、记忆文件内部结构、记忆向量索引细节
+（报告 §4/§5：这些来自逆向与用户观察，不得写成官方架构）。本轨的表结构、
+文件布局是本项目自定的，只对齐上面六条高层要求。
+
+## §2 现状
+
+- 应用状态散落在 `state_dir` 下的多个 JSON 文件（net.json、snapshots.json、
+  pool registry、host-state.json），无结构化存储、无统一审计、无备份恢复。
+- 记忆系统是另一个已闭合的项目（`~/workspace/memory-system`，v13 终态
+  730/730，常驻部署在 172）：Markdown 为可读源头、SQLite bank + FTS5 为派生
+  索引、bge-m3 语义检索（阈值 0.47）、claim 写库、忘记传播、备份恢复已做。
+  对外接口是真实 CLI：`node dist/cli.js <search|get|explain|forget-plan|
+  forget-confirm|backup|restore|export|import|...>`。
+- 凭证已分离（P3 authd）：真 token 只进客内守护进程，agent 只拿替身。
+  但**没有任何机制阻止应用状态里误写凭证**——状态 JSON 可含任意内容。
+- 客机记忆文件：不存在。`~/workspace` 经 chv-sync 同步到 Gitea；记忆若放
+  进 workspace 会进 git 历史，不符合“VM 是系统记录、备份恢复”的口径。
+
+## §3 改动清单（本轨）
+
+1. `cloud/chv/app_state.py`（新）：每 VM 一个 SQLite 状态库
+   `state_dir/<vm>/app-state.sqlite`（0600，WAL），表 tasks / goals /
+   sessions / audit（只追加）/ meta。写操作一律过“无凭证”守卫
+   （键名与值模式双重检查，拒绝时只报键名/模式、不含值）；备份用
+   sqlite3 在线备份 API + manifest（sha256），恢复先验 manifest、
+   先留 pre-restore 副本。
+2. `cloud/chv/memory_files.py`（新）：客机记忆文件接线。
+   - `MemoryFiles`：宿主侧镜像 `state_dir/<vm>/memory-home/`
+     （MEMORY.md + memory/*.md）读/列/写/追加，路径穿越守卫，写操作审计。
+   - `MemorySystemClient`：subprocess 调真实记忆系统 CLI
+     （search / get / explain / forget-plan / forget-confirm /
+     backup / restore / export），不重造检索引擎、不重造忘记传播；
+     CLI 未配置时本地模式（只动 Markdown 镜像，bank 忘记记为待办）。
+   - `pull_memory_home`：经 SSH + tar 拉取客机 `/home/chv/memory`
+     到宿主镜像（命令构造可测，传输走已有 SSH 通道）。
+   - `forget`：plan → confirm → 本地 Markdown 清行 → search 验证
+     查不到 → 审计，全程不含凭证值。
+3. `chv-guest/chv-memory.py`（新，纯标准库）：客内记忆文件操作
+   （list / read / append / forget / export），记忆家目录
+   `/home/chv/memory`（0700，chv 所有），在 workspace 之外——
+   记忆不同步到 Gitea。`build.sh` 拷入脚本并建目录。
+4. `docs/chv-production-readiness.md`：补 P7 一节。
+
+## §4 存储选型结论：SQLite，不是 Postgres
+
+| 维度 | Postgres（Muse 原样） | SQLite（本轨采用） |
+|---|---|---|
+| 部署成本 | 每 VM 一个 server 进程 + 端口 + 认证 + 数据目录；镜像 +150–250MB，常驻 RSS 约 50–100MB | 零 server，单个 0600 文件，WAL，空闲成本 0 |
+| 隔离 | VM 内 Postgres 才符合“VM 是系统记录”；宿主侧共享 Postgres 会把多用户状态集中到宿主，破坏每用户 VM 隔离 | 文件随 VM 走，`state_dir/<vm>/`，与 VM 同生死 |
+| 本仓既有模式 | 无 | 记忆系统本身用 SQLite 作 claim bank；cloud.db 的 AutoMemoryStore 回落 SQLite |
+| 并发 | 多写者 + 行级安全 | 单写者每 VM（进程内锁 + 文件锁守卫）；客机 cell 绝不直读库文件 |
+
+**差距（诚实写明，不冒充 Postgres）**：无多写者服务器、无网络访问、
+无行级安全、无内置复制（复制 = 备份/恢复路径 + Gitea 只管仓库内容）。
+DDL 用 SQLite 与 Postgres 共通的受限子集（TEXT/INTEGER/REAL 列、TEXT id、
+无 AUTOINCREMENT、无 SQLite 专有语法、参数化查询），仓库层只依赖连接
+工厂；将来换 Postgres = 换工厂 + 同一份 DDL + 可序列化隔离说明。
+
+## §5 诚实边界
+
+- 记忆**引擎**不在本轨：检索、bank、FTS5、语义索引、忘记传播、审计
+  全是记忆系统 v13 的已有实现，本轨只调它的 CLI。CLI 不可用时
+  降级为本地 Markdown 模式，bank 忘记明确记为待办，不谎称已忘。
+- 备份恢复演练在本机做（备份→改坏→恢复→校验条数与内容一致）；
+  真机上的定时备份是 P8（crons）那轨的活，本轨只留接口与一次手工演练。
+- “忘记”是尽力删除 + 验证查不到，不是密码学擦除：已备份的快照里
+  仍有旧内容（与记忆系统 CLI 的 backup 语义一致：快照在 home 之外，
+  忘记不 scrub 快照），差距表与用户可见文案里写清。
+- 单元内直读状态库被拒是**构造性保证**：库文件在宿主 `state_dir`，
+  不在客机磁盘镜像里，cell 物理上够不着；测试钉住“库路径不在
+  客机 rootfs 内”与“客机脚本无 state 库引用”。
+
+## §6 真机待验证清单（round-11 之后，测试机空闲后）
+
+1. lite12 镜像含 `chv-memory.py`，`/home/chv/memory` 存在且 0700。
+2. 客内 `chv-memory.py` append → 宿主 `pull_memory_home` → 宿主镜像
+   内容一致；再经 CLI search 能查到。
+3. CLI forget-confirm 后，客机与宿主两处都查不到；审计有 forget 记录。
+4. 状态库备份→删库→恢复→条数与内容一致；备份文件里无 token 值
+   （以测试 token 做扫描）。
+5. 单元内（nspawn cell）`ls /home/chv/memory` 与直读库路径均被拒；
+   经 executor 的记忆读接口可通。
+6. 备份恢复演练在真机跑一遍（含 pre-restore 副本存在）。
+
+## §7 与 P1/P2/P3/P4/P5/P6 的接口
+
+- P3 authd：状态库与记忆文件绝不存凭证值（守卫 + 否定测试）；authd
+  的 vault 不动。
+- P2 cell/broker：cell 不直读状态库；客机记忆脚本跑在 cell 外（与
+  chv-sync 同级），由 executor 经 SSH 调用。
+- P1 常驻池：常驻 VM 的状态库与记忆家目录随 VM 持久化（文件在
+  state_dir/<vm>/，VM pause/resume 不丢）；VM 销毁时状态库与记忆
+  家目录随任务盘清理策略走（删盘即删，不留孤儿——接 orphans 口径）。
+- P4/P5/P6：不碰浏览器、Sentinel、privsep；P6 的安全检查层如需审计
+  记忆读，读本轨的 audit 表（只读）。

+- **子代理群：没有。** 只有模型层的子代理名（`cloud/harness2.py`
+`subagent_names`，prompt 树里的名字），没有执行层的并行派发、没有隔离、
+没有工具注册。
+- **后台回访通知：没有“值得呈现”评估。** `cloud/push.py dispatch_event`
+按订阅派发终态（completed/failed/goal-unmet 等）；自动化模块 docstring
+已写明“不新写通知代码”。无去重、无节流——同一终态可重复派发。
+- **每任务浏览器子代理：没有。** P2 的 `chv-browser.py` 是常驻进程，
+`close` 只关当前页、进程继续跑、等下一次 open；broker 固定转发到
+`/run/chv/browser.sock`。状态跨任务复用。

+| `cloud/chv/browser_tasks.py`（新） | 每浏览器任务一个实例：建/绑/毁生命周期、单实例单任务（复用即错、毁后复用即错）、每实例独立状态目录；transport 接口注入（测试用 fake） | 本轨 |
+| `cloud/automations.py`（改） | 只加重试/停用所需的列与抢单入口（`max_retries`、`retry_backoff_seconds`、`consecutive_failures`、`next_retry_at`、`paused` 状态）；host.py run-due **不动**（host 侧唯一执行器，见该模块 docstring） | 本轨 |
+
+**P7 状态落点（更新 2026-11-07 06:39；迁移已完成，round-12 更新）：**
+P7 已完成并提交（分支 `feat-chv-muse-p7`，提交 `29fa0c8`：每 VM
+一个 SQLite 状态库 AppStateStore，0600 WAL，
+tasks/goals/sessions/只追加 audit/meta）。**round-12 已把三处登记
+迁到 AppStateStore**（分支 `feat-chv-muse-round12`）：宿主级库
+`state_dir/app-state.sqlite`（`host_state_db_path`，与 per-VM 库
+同库不同文件），命名空间 `p8-swarm` / `p8-ledger` /
+`p8-browser-tasks`，一行存整份登记文档；旧 JSON 文件首次加载时
+自动导入并改名 `.migrated`；KV 行损坏/库打不开时回空结构
+（fail-safe，下次成功保存即覆盖自愈）。测试钉在
+`cloud/tests/test_chv_muse_round12.py`（P8MigrationTest）与
+`test_chv_muse_p8.py`（损坏行恢复 + 旧文件导入）。crons 的状态
+仍在 `automations` 表，未动。
+
+**客机侧跟进（本轨只写规约、不改 P2 的文件）：** 每任务浏览器实例的客机
+进程拉起/销毁在 P2 的 `chv-guest/chv-broker.py`（`browser` 操作固定转发到
+单例 socket）里改：每浏览器任务起一个全新的 `chv-browser.py`（每任务
+socket），`close` 后杀掉进程。P2 的文件不在本分支基线里，本轨不复制、不
+分叉，规约写进本表 §6，留给 round-12 集成时落在 P2 分支上。
+
+**客机侧跟进（round-12 决定：未做，留给真机轨）：** round-12 核实后未做，
+原因三条：① `chv-browser.py` 的请求协议里没有任务 id 字段（只有
+open/snapshot/screenshot/close/ping），broker 分不清请求属于哪个浏览器任
+务，改 broker 之前须先改协议 + 调 broker 的调用方；② 进程拉起/销毁涉
+及以 chv-browser 身份起进程、socket 就绪等待、close 后杀进程与僵尸回收、
+broker 重启后的残留清理，在没有真机验证的情况下盲改，坏了就是每任务浏览
+器全断；③ 本地只能用假浏览器进程测生命周期，真 Playwright + 真
+chromium-headless-shell 的起停只能在真机上验。留给真机轨：先在真机上改
+协议（请求加 task_id）→ broker 按任务拉起/杀进程 → 连续两任务端到端

+## 4. 自定数值清单（全部是本项目自定，非 Meta 官方值）
+
+| 数值 | 本项目自定值 | 说明 |
+|---|---|---|
+| cron 最小间隔 | 60 秒（沿用现有 `MIN_INTERVAL_SECONDS`） | 已有，不新定 |
+| cron 最大间隔 | 30 天（沿用现有 `MAX_INTERVAL_SECONDS`） | 已有，不新定 |

+| 工具名长度上限 | 100 字符 | 与自动化名上限同款 |
+
+## 5. 诚实边界
+
+- B3 的“VM 需要足够资源”是容量要求，不是本轨能代码保证的：本轨只做上限与
+隔离，宿主容量仍由部署方保障；群上限 8 是防炸宿主的默认值，不是性能承诺。
+- swarm 层**不执行工具**：工具调用意图只登记与审计，真正执行在子代理自己的
+VM/单元里（P1 常驻池 + P2 单元是底座）。“子代理构建自己的工具”在本轨指
+注册进群内工具表、可被审计、可被别的代理复用调用名——不是沙箱外任意执行。
+- “实质新内容”的判定是确定性规则（新产物/新改动文件/显式 notify 标志），
+不是模型判断；模型觉得重要但规则判无新内容时，以规则为准、只记日志。
+- cron 重试只针对 failed/interrupted 的执行；超配额跳过（skipped_quota）
+不是失败，不进重试（沿用 automations 模块现有口径）。
+- 通知账本先走原子 JSON 文件，P7 存储（`feat-chv-muse-p7` 提交
+`29fa0c8` 的 AppStateStore）已落地，集成轨再迁移；迁移前账本丢了只
+影响去重（可能重复通知一次），不影响任务执行本身。
+
+## 6. 真机待验证清单（round-11 与 P4/P5/P6 之后，等通知）
+
+1. cron 端到端：定义在测试机上按间隔触发、失败重试 3 次后停、停用后不再触发。
+2. 群端到端：3 个子代理在各自 VM 里并行跑、互不可见对方工作区。
+3. 回访通知端到端：后台任务完成后有新内容才通知、无新内容不通知、同一原因
+1 小时内不重复通知。
+4. 每任务浏览器实例端到端：连续两个浏览器任务各起全新实例、第二个看不到
+第一个的截图与快照状态（需 §3 客机侧跟进先落地；round-12 未做，见 §3）。
+5. 账本迁移：**已完成（round-12）**——通知账本与另两处登记已迁到宿主级
+AppStateStore（见 §3 更新），去重语义不变，测试钉住；真机上只需确认
+升级后旧 JSON 文件一次导入、不丢去重状态。

+# 对齐 Muse P9 差距表：推理与遥测受限通道
+
+> 先写表再动手。依据：`~/workspace/research_notes/meta-muse-ai-architecture-20261101-0755/report.md`
+> （Meta 官方 security.muse.ai 与设计文 2026-09-08 为准；第三方拆解只作参考，不得把逆向细节写成官方架构）。
+> 基线：`06c3e17`。分支：`feat-chv-muse-p9`。本地做，不推、不合、不部署。
+
+## 1. 现状 vs Muse 官方要求
+
+| # | Muse 官方要求（security.muse.ai / 设计文） | 现状（基线 06c3e17） | 本轨做法 |
+|---|---|---|---|
+| 1 | 推理与遥测代理是通向外部基础设施的**受限通道** | 模型调用无收敛点：`host.py` 起 `codex app-server`，provider=`sub2api` 时 `-c` 覆盖 base_url（取 `SUB2API_BASE_URL`）；provider 为空时 codex 用自身 config.toml 默认网关（xcmapi 路径），执行器侧没有任何出口校验 | 新模块 `cloud/chv/inference_channel.py`：单一出口点 + 执行器 `_run_with_vm` 起 VM 前预审（Sentinel 评估）；`host.py` 的 `_server_command` 做结构校验（https、无 userinfo、主机在 allowlist 内）当第二道防线 |
+| 2 | VM 发送**有限数据**用于推理与遥测（安全文**未给字段级清单**） | 无任何遥测：任务元数据只进宿主日志与审计 spill，无字段清单、无采样、无发送路径 | 新模块 `cloud/chv/telemetry.py`：字段级白名单（只含任务级元数据，见 §2）；采样率可配；落盘 `<state_dir>/telemetry.jsonl`，发送失败只记日志、不影响任务 |
+| 3 | 推理轨迹（对话往返、工具调用、子代理交接）在**去除关键个人身份信息后**可用于训练新检查点；用户可**一键退出训练** | 无训练上传、无开关 | 训练退出开关（`training_opt`，见 §2）：状态持久化在 `<state_dir>/training-opt.json`，关后轨迹类事件不再产生；开关变更进审计。**默认值开是本项目决定，非 Meta 官方值**（报告注明帮助中心原文未逐字确认默认开启） |
+| 4 | 当前 VM 的 Meta 访问边界（官方明确，非营销口径）：运营政策限制 Meta 人员访问用户数据，但**并不阻止** Meta 在必要时为支持、保障或运营而访问；“连 Meta 也看不到”是未来 Confidential VM 的目标 | 无边界说明 | `docs/chv-access-boundary.md`：只写文档 + 审计钩子，不冒充技术上不可访问；Confidential VM 明确列为未做 |
+| 5 | 广告隔离：不把用户对话或 VM 数据分享给广告系统；但浏览互联网时表现为用户活动、可能间接影响广告 | 无口径 | 只记为口径（见 §4），不用写代码 |
+| 6 | Sentinel 是连接器动作与全部网络出口的唯一权限机构 | P3 已做 Sentinel 最小审批、P5 已做纵深（本基线**都没有**；P3 在 `feat-chv-muse-p3` 分支 a90cf78，P5 在 `feat-chv-muse-p5` 分支 25bcd35） | 推理通道走 Sentinel 审批，不重复造审批：`cloud/chv/sentinel.py` 从 **P5 的 25bcd35 拷入**（P5 版已是 P3 的超集，顶层仍只用标准库），再加 P9 的 inference 条目（三张表里加 `inference`：scheme https、端口 443、路径 `POST /v1/responses` + `GET /v1/models`）；合入时以本文件为准（它是 P3+P5+P9 的并集） |
+
+## 2. 本项目自定清单（非 Meta 官方值，逐项注明）
+
+### 2.1 遥测字段白名单（`telemetry.py`）
+
+只含任务级元数据，**绝不含**对话原文、文件内容、密钥、个人身份信息：
+
+| 字段 | 含义 | 来源 |
+|---|---|---|
+| `task_id` | 任务 id | 任务 dict |
+| `vm_id` | VM 名 | 执行器 |
+| `provider` | 模型 provider（`sub2api` / `xcmapi`） | 通道决策 |
+| `model` | 模型名 | 任务 dict |
+| `status` | `completed` / `failed` / `interrupted` / `timeout` | 运行结果 |
+| `started_at` / `ended_at` | 起止时间戳（秒） | 执行器 |
+| `duration_ms` | 耗时毫秒 | 执行器 |
+| `tokens_in` / `tokens_out` / `tokens_total` | token 数 | host.py 回传的 usage（未回传时记 `null`，**不编造**） |
+| `turns` | 回合数 | 运行结果 |
+| `tool_calls` | 工具调用次数 | 运行结果 |
+| `sampled` | 是否被采样命中 | 采样器 |
+
+不在白名单里的键一律丢弃；键名含 `key` / `token` / `secret` / `password` / `prompt` /
+`content` / `text` / `message` / `email` / `name` 的一律丢弃（防误带）。采样率
+`CHV_TELEMETRY_SAMPLE_RATE`：0.0–1.0，默认 `1.0`（全量，任务级元数据量小）；按
+`task_id` 确定性采样（同一任务每次判定一致，可测试）。
+
+### 2.2 轨迹事件（训练用）
+
+轨迹类事件只含回合级元数据（回合数、工具名、耗时），**不含任何文本**；去标识化
+= 只出元数据、不出内容。退出开关关后，轨迹类事件**不再产生**（不是产生后丢弃）。
+
+### 2.3 推理通道上限（自定）
+
+| 项 | 环境变量 | 默认 | 范围 | 说明 |
+|---|---|---|---|---|
+| 单次请求超时（秒） | `CHV_INFERENCE_TIMEOUT` | `120` | 10–600 | 与 `host.py` 的 `Server.request` 默认超时一致；非法值即 ValueError |
+| 重试上限（次） | `CHV_INFERENCE_MAX_RETRIES` | `1` | 0–5 | `Server.request` 的 BrokenPipe 重连次数上限；默认 `1` 即**保持现有行为不变**（现为 `range(2)`）；模型回合级重试仍是 worker 的 `max_retries` 语义，本轨不动 |
+
+### 2.4 训练退出开关默认值
+
+默认**开**（轨迹可用于训练）。这是**本项目决定，非 Meta 官方值**：报告注明帮助中心原文未逐字确认
+默认开启。开关状态持久化、变更进审计；关后立即生效（后续轨迹不再产生）。
+
+### 2.5 推理出口 allowlist 与 origin 规则
+
+- provider=`sub2api`：origin 取 `SUB2API_BASE_URL`（去尾斜杠）；未知 provider 标签与
+  provider 为空一样走默认网关（与 host.py `_server_command` 一致——标签本身不决定
+  origin，origin 永远只取 operator 配置的 env）。
+- provider 为空或未知标签（xcmapi 路径，codex 用自身 config.toml 默认网关）：执行器
+  **看不到** origin，改取 `CHV_INFERENCE_ORIGIN`（operator 显式配置，如 `https://xgapi.lol`）；
+  未配即 `ask`——审计 + 任务停止（fail-closed），**不静默放行**。部署迁移：现网 xcmapi 部署
+  须补设 `CHV_INFERENCE_ORIGIN`，否则任务会在预审处停下（这是有意行为，见 §3）。
+- scheme 规则（2026-11-07 全量套件复核时修正——初版只认 https 是错的）：
+  - https：公网网关（如 xgapi.lol），端口只接受 443（或缺省）；
+  - http：**只接受本地中继**——字面环回/私网 IP 主机（如 cloud/README.md 的 sub2api 网关
+    文档形状 `http://172.17.0.1:28084`，Docker 桥接 IP），端口保留；http + 公网主机名/IP、
+    http + 主机名一律拒绝。主机名一律不算本地中继（DNS 结果不可信）。
+  - 本地中继分支：字面 IP 无 DNS、无重绑定，跳过 Sentinel 的 DNS/SSRF 步；allowlist 与
+    单次能力（P3 默认档）照常执行；解析器不被调用（测试用必错解析器钉住）。Sentinel 表里的
+    inference scheme/端口仍只写 https/443——本地中继不走 `evaluate`，不要“顺手”把 http
+    加进表（那会放宽公网路径）。
+- 路径规则（`inference` 连接器）：只放 `POST /v1/responses` 与 `GET /v1/models`；
+  `/v1/models` 是否必需**待真机核实**（codex 启动时是否拉模型列表），若非必需则收紧为只放
+  `/v1/responses`。公网路径：解析到私网 IP 即 deny（SSRF，复用 Sentinel）；解析失败即 deny。
+- 任务级 env 合并：门的 origin 取任务级 `extra_env`（网关配置随任务来，如 worker 的
+  `_gateway_env`）覆盖执行器进程 env；origin 非法（http 公网、带 userinfo、https 非 443
+  端口）记 deny，不抛裸 ValueError。报错/审计原因不带 origin 原值（http URL 里可能含
+  userinfo，见 `resolve_inference_origin`）。
+
+## 3. 改什么（文件清单）
+
+| 文件 | 动作 |
+|---|---|
+| `cloud/chv/sentinel.py` | **新增**：从 P5 分支 `25bcd35` 拷入（P5 版已是 P3 的超集，顶层仍只用标准库），再加 P9 的 inference 条目（三张表：路径、scheme、端口）；合入时以本文件为准（P3+P5+P9 的并集） |
+| `cloud/chv/inference_channel.py` | **新增**：受限推理通道（origin 解析、allowlist、上限校验、Sentinel 预审、`InferenceChannelDenied` 之外的 Decision 返回） |
+| `cloud/chv/telemetry.py` | **新增**：遥测事件（字段白名单、采样、落盘、永不抛错）+ 训练退出开关（持久化、审计） |
+| `cloud/chv/executor.py` | **改动**：`_run_with_vm` 起 VM 前调推理预审（`_inference_gate`）；allow 通过、deny/ask 审计 + `ChvFailure` 停止，不起 VM。`execute()`（只读 status，不跑模型回合）不设门 |
+| `host.py` | **改动**：`_server_command` 的 sub2api origin 结构校验（https、无 userinfo、主机在 allowlist 内）；`Server.request` 默认超时与重连上限改走 `CHV_INFERENCE_TIMEOUT` / `CHV_INFERENCE_MAX_RETRIES`（默认 120 秒 / 1 次，即现有行为） |
+| `cloud/tests/test_chv_muse_p9.py` | **新增**：全部覆盖（见 §5） |
+| `docs/chv-muse-p9-gap.md` | **新增**：本文件 |
+| `docs/chv-access-boundary.md` | **新增**：运营访问边界说明 |
+
+**不碰的**：`cloud/chv/config.py`（通道读 `env` 字典，不进 VM 配置片段；架构测试无“env 必须进片段”的规矩）、
+P3 的 authd、P5 的 eBPF 污点（P5 已结论：本 VM 的 bpf() 被 seccomp 挡，不可行；本轨不重复探）、
+P6 的确定性检查层（审计复用执行器已有的 `_emit`，不另造审计接口）、worker 的 `max_retries`、
+guest 镜像（`host.py` 是标准库单文件，`/app/host.py` 拷入方式不变——本轨对 `host.py` 的改动只用标准库）。
+
+## 4. 诚实边界
+
+- 本轨是**决策层 + 预审**，不是网络层强制：客内 codex 直连的强制仍靠 Tinyproxy 白名单 + 宿主防火墙
+  （第三棒落地中）。不要把本轨写成“出口已全部经 Sentinel”——P3 的模块 docstring 同款声明。
+- provider 为空时执行器看不到 codex config.toml 里的 origin：本轨用 `CHV_INFERENCE_ORIGIN`
+  显式配置 + 未配即 ask 兜底；这不是“读到了 config”，部署时须补 env（见 §2.5）。
+- 遥测目前只落盘 `<state_dir>/telemetry.jsonl`，**没有**向外部遥测端点发送的路径；“发送失败不影响任务”
+  指落盘失败也不影响任务。向外部发遥测是后续工作，需另批。
+- 训练轨迹目前**没有**上传路径：开关管的是“轨迹类事件是否产生”；上传通道本身不存在，开关是为
+  上传通道预留的门禁，不是已接通的上传。
+- token 数只取 host.py 回传的 usage；codex 未回传时记 `null`，不估算、不编造。
+- `GET /v1/models` 是否必需未验证（见 §2.5），真机核实前不收紧、也不放宽。
+- `sentinel.py` 是从 P5 分支（25bcd35）原样拿来的超集版本：其中 `capability_for` 的非 one-shot
+  分支在运行时 import `cloud.chv.capabilities`——该模块是 P5 的文件，本轨基线 06c3e17 里没有。
+  本轨只走 one-shot 默认档，运行时不触及该分支（新测试 51/51 证明）；mypy 会报 1 处
+  `import-not-found`，待 P3/P5/P9 集成轨把 capabilities.py 带进来后消除，不在本轨另造一份。
+  其余 mypy 报错与基线一致：`executor.py:1396/1401`（`out` 未注解）与 `marker_tools.py:142`
+  是 P3 已记录的基线问题，本轨未碰。
+
+## 5. 测试清单（`test_chv_muse_p9.py`，全部用标准库与 mock，不联网、不启动真实 VM）
+
+- origin 解析：合法 origin 通过；缺 `SUB2API_BASE_URL` 即错；http 公网主机名/IP 被拒；
+  http 本地中继（字面环回/私网 IP，如 `http://172.17.0.1:28084`）通过且端口保留；
+  URL 带 userinfo 被拒；尾斜杠被剥掉；未知 provider 标签走默认网关（不 deny）。
+- allowlist：`CHV_INFERENCE_ALLOW_HOSTS` 显式覆盖生效；默认即 origin host。
+- 上限校验：超时/重试非法值（非整数、越界）即 ValueError；默认值 120/1。
+- 预审决策（假解析器，不联网）：allow（公网 IP + 白名单 + 路径内）；deny（解析到私网 IP、
+  origin 非法）；ask（主机不在白名单、provider 为空且未配 `CHV_INFERENCE_ORIGIN`）；
+  路径越界（`GET /v1/admin`）即 deny；能力绑定（单次、300 秒）；本地中继 allow（不查 DNS，
+  用必错解析器钉住）与本地中继 ask（allowlist 不含该主机）。
+- 旁路：直连（非通道）调模型无入口——执行器 `_run_with_vm` 前必过预审（mock 执行器验调用顺序：
+  预审 deny 时 `wake_vm` 未被调用）；任务级 `extra_env` 的 origin 被合并进预审（worker 网关
+  路径），非法 origin 转 deny 而不是裸 ValueError。
+- 遥测：白名单外键丢弃；`prompt`/`content`/`api_key` 类键丢弃；采样确定性（同一 task_id 多次判定一致；
+  采样率 0 全丢、1 全留）；落盘失败（state_dir 不可写）不抛错、不影响任务；token 未回传记 `null`。
+- 训练开关：默认开；关后轨迹事件不再产生、任务级遥测不受影响；开关变更持久化 + 审计有记录；
+  状态文件损坏时 fail-closed（当作关处理，记日志）。
+- host.py：`_server_command` 的 origin 结构校验（http 公网被拒、本地中继通过、allowlist 不匹配
+  被拒、合法通过）；`Server.request` 默认超时与重试上限走 env（mock 验默认值 120/1 与 env 覆盖）。
+- 旧测试 harness：5 个文件的 `make_exec` 配了假 origin（`SUB2API_BASE_URL` 与
+  `CHV_INFERENCE_ORIGIN` 均为 `https://xgapi.lol`）+ 假公网解析器——这是新 fail-closed 门
+  要求的测试配置，不是放宽门；门的 deny/ask 行为由本轨新测试钉住。
+
+## 6. 真机待验证清单（排队，测试机空闲后；第三棒 → round-11 → P4/P5/P6 → 本轨）
+
+1. `GET /v1/models` 是否必需：真机跑一轮 turn，确认 codex 是否调它；必需则保留，不必需则收紧为只放 `POST /v1/responses`。
+2. 预审对真实 xgapi 主机的判定：`https://xgapi.lol` 解析后 IP 是否干净（不在 SSRF 挡截网段内）；若解析到被挡网段，记录真实判定、不绕过。
+3. `CHV_INFERENCE_ORIGIN` 未配时 xcmapi 任务是否如实停在预审（ask + 审计），配上后是否放行。
+4. 本地中继真机：`SUB2API_BASE_URL=http://172.17.0.1:28084` 的任务预审是否放行（本地中继分支）、
+   真实 turn 是否走通该中继；同时确认 http 公网 origin 在真机仍被拒。
+5. 真实 turn 的 usage 是否回传：遥测里的 token 字段是否从 `null` 变成实数。
+6. 遥测落盘文件在真实任务后是否存在、内容是否只有白名单字段。
+7. 训练开关在真机上的持久化：开关翻转后重启执行器，状态是否还在。
+7. 超时/重试上限在真机上的表现：长 turn 是否在 `CHV_INFERENCE_TIMEOUT` 处超时（只记录、不主动造超时）。

+- Chromium 的所有权从浏览器子代理移到单元外 CDP broker：
+  `chv-guest/chv-cdp-broker.py`（新，用户 `chv-browser`）独家
+  `chromium.launch(headless=True, args=LAUNCH_ARGS)`；子代理
+  `chv-guest/chv-browser.py`（P2 版基础上重构）改为 broker 的
+  客户端，不再直连 Playwright，本文件里不再有 playwright import。
+- a11y-tree-only 收紧到底：快照只出无障碍树 + 标题/URL；全部回包与
+  错误信息过 `sanitize_error`（去 HTML 标签、截断 200 字符、凭据形
+  key=value 与 sk- 形 token 打码）；回包先过 `response_leaks`
+  检查（ws 端点、DevTools 路径、HTML 标签即拦截）；Playwright
+  调用白名单 + AST 测试钉住两个客机脚本里不存在脚本注入面
+  （evaluate/add_script_tag/add_init_script/expose_function/
+  set_content/keyboard/mouse 等属性名）。
+- DevTools 不暴露：启动参数白名单无 `--remote-debugging-port`、
+  无 `devtools=True`；CDP 端点（ws 地址）绝不进任何响应。
+- 暂停状态机：CDP broker 持 `active/paused`，`pause`/`resume`/
+  `status` 操作；暂停时除 ping/resume/status/list_asks/resolve_ask
+  外一切操作拒绝；自动暂停触发源：观测到导航 POST、下载命中拦截规则。
+- 确定性分类器（规则，不冒充模型）：`detect_injection` 启发式
+  （中英文各 6 条模式，命中只标注 `untrusted` + `injection_flags`，
+  快照恒带 `untrusted_input: true`）；`detect_form_risk` 扫密码/

+  由运维构建时填入；无在线更新。
+- 文件型待审批队列 `/run/chv/ask-queue/`（与 P3 ApprovalQueue 同语义：
+  pending/allowed/denied；`list_asks`/`resolve_ask` 操作；`allowed`
+  解除暂停，`denied` 关当前页）。
+- 测试：`cloud/tests/test_chv_muse_p4.py` 36 项全过（含否定测试：

+
+## 17. 对齐 Muse P6 轨 feat-chv-muse-p6（privsep worker + 确定性安全检查层）
+
+本节是准备工作，不是启用结论。本轨只到本地提交，不合并、
+不部署、不推；生产就绪与动态安全的外部关卡原样未动。
+基线 06c3e17（P1/P2/P3 之前的基线，不含 P3 的 authd/sentinel
+代码——本轨与 P3 的接线走文件/socket 协议；round-12 合入后 P3
+已在树里，接线走真实 P3 代码，见集成说明）。
+
+### 17.1 本轨改动
+
+- `cloud/chv/safety.py`（新）：`UntrustedData` 来源标记、
+  `InjectionScanner` 确定性规则（阻断/标记/放行三档）、
+  `redact_secrets`（审计前脱敏）、`AuditLogger`（只记指纹，
+  永不记值）、`audit_inference_request/response`（进出核心推理
+  的审计入口）。规则覆盖：指令覆盖（中英）、shell 执行链、
+  可疑 URL、分隔符隐藏指令；不覆盖：改写/编码指令、图片/
+  附件/二进制内指令、上下文相关社会工程（见 §17.3）。
+- `cloud/chv/privsep.py`（新）：`ConnectorSpec` 凭证白名单
+  （gitea 只含 GITEA_TOKEN）、`WorkerRequest/Response` 类型化
+  协议（request_id 绑定 + 64KB 上限 + 未知操作/字段拒绝）、
+  `PrivsepServer`（Unix socket，SO_PEERCRED 只放 root/chv，
+  仓目录限定 ~/workspace，git 只走 authd 凭证 helper，绝不
+  直读真 token）、`PrivsepClient`（薄客户端，响应再扫一遍，
+  取 worker 与客户端两者中更严的裁决）。
+- `chv-guest/chv-gitea-worker.py`（新）：systemd 沙箱化 worker
+  守护进程（`chv-guest/chv-gitea-worker.service`，NoNewPrivileges
+  + ProtectSystem + PrivateTmp + 凭证白名单环境变量）。
+- `chv-guest/chv-sync-worker-client.py`（新）：agent 侧薄 CLI
+  （只解析参数、传类型化参数，走 Unix socket）。
+- `chv-guest/chv-sync.sh`：pull/push/status 走 worker（socket
+  在时），否则旧直连路径 + stderr 警告（不静默回落）。
+- `cloud/chv/executor.py`：`_run_guest` 前后加审计钩子
+  （`_audit_inference_request/_audit_inference_response`），
+  钩子失败不影响主流程。
+
+### 17.2 本轨量化结果（实测）
+
+- 新测试 `cloud/tests/test_chv_muse_p6.py` 43 项，全过
+  （root 身份跑时 uid 否定测试 skip 1 项——该测试只在
+  非 root 身份下才有意义）。
+  含否定测试：worker 越权取凭证被拒、worker 直连外网被拒
+  （无直连代码路径）、注入文本被标注/阻断、审计里无密钥值、
+  仓目录越界被拒、request_id 错配被拒、worker 崩溃不拖垮
+  agent（失败分类 WorkerRefusal）。
+- 差距表：`docs/chv-muse-p6-gap.md`（现状 vs Muse 官方要求、
+  改什么、诚实边界、真机待验证清单）。
+- mypy 在新增文件上干净；剩余报错 4 处全是基线旧错
+  （executor.py:1396/1401 的 `out` 未注解、
+  marker_tools.py:142），未动。
+
+### 17.3 确定性检查层的覆盖边界（诚实版）
+
+能拦：字面指令覆盖（中英）、shell 执行链、可疑 URL、
+分隔符隐藏指令、git 输出里的注入文本（worker 侧与客户端
+双重扫描）。不能拦：改写/编码后的指令、图片/附件/二进制
+内指令、上下文相关的社会工程、需要理解语义的间接注入。
+这些需要模型分类器，本轨不冒充。真机待验证清单见差距表
+§4（worker 真实沙箱、SO_PEERCRED 真实 uid、超时/崩溃、
+auditd 审计、与 P3 authd/Sentinel 的真接线）。
+
+## 18. 对齐 Muse P7：状态与记忆分离（feat-chv-muse-p7）
+
+- 选型：SQLite 每 VM 一库（`state_dir/<vm>/app-state.sqlite`，0600，
+  WAL），不是 Postgres。理由与差距见 docs/chv-muse-p7-gap.md §4：
+  轻量 VM 跑 Postgres server 太重；宿主侧共享 Postgres 破坏每用户
+  VM 隔离；DDL 用两方共通受限子集，换 Postgres = 换连接工厂。
+- 记忆引擎不重做：调记忆系统 v13 的真实 CLI（search/get/explain/
+  forget-plan/forget-confirm/backup/restore/export）；CLI 缺位时
+  降级本地 Markdown 模式，bank 忘记记为待办。
+- 记忆家目录客内 `/home/chv/memory`（workspace 之外，不同步到
+  Gitea），宿主镜像 `state_dir/<vm>/memory-home/`；客内脚本
+  `chv-memory.py`（纯标准库）经 SSH 调用。
+- 凭证绝不进状态库与记忆文件：写操作过无凭证守卫（键名 + 值模式），
+  备份文件无 token 值（测试钉住）；audit 表只追加。
+- “忘记”是尽力删除 + 验证查不到，不是密码学擦除：已备份快照里
+  仍有旧内容（与记忆系统 CLI 语义一致），差距表 §5 写清。
+- 真机待验证：见 docs/chv-muse-p7-gap.md §6（lite12 镜像、双向
+  拉取、双向忘记、备份恢复演练、cell 内直读被拒）。
+
+## 19. 对齐 Muse P11：用量计量与配额执行（分支 feat-chv-muse-p11）
+
+- 四项计量：token/月（读既有 `cost_records`，推理通道记账点，不另开
+  采集路）、消息/天（哈希链账本）、并发任务（`queued`/`running` 计数）、
+  存储（本机任务 worktree 实测 + 附件大小）。
+- 三档档位是**提案**（Free $0 / Paid $19/月 / Heavy $99/月，用户委托按
+  市场定，未确认；不是 Meta 官方定价），payload 与文档都带 `proposal`
+  标注。无档位行的用户不受档位门约束，只受既有 USD 配额约束。
+- 超限回 402（`quota_exceeded` + `dimension`）；进行中回合不掐断——
+  档位门是纯准入判定，无任何终止在跑任务的 API。
+- 80% 提醒（默认，可配），每维度每窗口只记一次。
+- 账本 `usage_ledger` 追加写哈希链，篡改可发现；账本不含对话原文、
+  文件内容、密钥。token 账本复用 `cost_records`（全仓无 UPDATE/DELETE），
+  不重复记。
+- 端点：`GET /users/me/usage`、`GET/POST /admin/tiers`（全局管理员）。
+- 不接真实计费、不碰真实钱；Stripe/支付/开票待用户另行批准。
+- 已知待决（见 `docs/chv-muse-p11-gap.md` §5）：既有 USD 配额路径的
+  worker 30 秒轮询掐断与“进行中回合不掐断”语义不一致；并发超限按
+  任务书即拒，与设计文档 §6.2 的“排队”不同；cloud 任务存储量不到；
+  Heavy 消息/天提案未给，本轨定为不限。
+- 真机待验证：真实 token 回传下的月度累计与 402、真实多任务下的并发门、
+  真实 worktree 下的存储门、提醒只发一次、账本并发写不断链。
+
+## 20. 对齐 Muse round-12 集成：P4～P12 合入（分支 feat-chv-muse-round12）
+
+- 合入顺序与提交：P4 c24cc0b → P5 d1c9a8e → P6 b0b9f5e → P7 320cd36 →
+  P8 240949e → P9 90c42f6 → P10 b55b49b（acf98f8 的 cherry-pick，只含
+  P10 自有 diff，基线已含的 P3/P5 未重复合）→ P11 77743e7 → P12
+  466cf7e。基线 round-11 HEAD 29d3a5a。之后 round-11 在 Gitea 上前
+  进到 717efc4（V-9 真机修复移植），本轨以合入提交 5d5041b 把它并
+  进来：build.sh runcmd 在 start chv-authd 之后、chv-sync boot 之
+  前加 chown guest-env 行；lockfile 两脚本 DECLARED_SOURCES 加 P2
+  三件套；executor 新增 `_wait_guest_env_usable`（密钥已投递时等
+  guest-env 对 SSH 用户可读再报 ready，超时关 VM 抛
+  guest_env_not_ready，`_boot_vm` 调用）；hostkeys 补 V-9 根因注释；
+  test_chv_gitea_sync.py 新增 5 项。build.sh 冲突唯一一处（runcmd
+  行），按并集解：取 717efc4 的 runcmd（含 chown），保留 HEAD 的 P4
+  三件套 + P7 chv-memory copy-in 行；executor.py 干净合入。
+- 冲突处理（逐项）：① executor.py：P9 的 `_inference_gate` 插到 P1
+  分发器 `_run_with_vm` 之前，gate 调用为分发器第一条语句（deny/ask
+  在常驻 resume 与冷启动 wake 之前 fail-closed）；P9 自己的旧版本
+  `_run_with_vm` 丢弃——其本体与 P1 `_run_cold` 逐字节相同（P1 的
+  verbatim 搬运），合入时一度误删 `_run_cold` 体致 dispatch 回 None，
+  已从 HEAD 原样恢复并由测试钉住；sentinel.py 取 P9 超集版。
+  ② build.sh/buildinfo.py：按 hunk 合，authd 三件套 + P2 三件套 +
+  P4 三文件 + P7 chv-memory 全在 contents 里，GT 哈希仍为已批准的
+  49ffe090…。③ docs §15 撞号：P4→§16、P6→§17、P7→§18、P11→§19，
+  顺序顺延，无覆盖。④ P4 弄坏的 P2 测试改走假 CDP broker，断言不变。
+- AppStateStore 迁移（本轨做完）：P8 三处登记（swarms.json /
+  notification-ledger.json / browser-tasks.json）迁到宿主级库
+  `state_dir/app-state.sqlite`（`host_state_db_path`，与 per-VM 库
+  同库不同文件），命名空间 `p8-swarm` / `p8-ledger` /
+  `p8-browser-tasks`，一行存整份文档；旧 JSON 首次加载自动导入并改名
+  `.migrated`；KV 行损坏回空 fail-safe。P12 审计 JSONL 迁到
+  `audit_trail` 表（`StoreAuditTrail`，同一记录形状与哈希链），
+  `migrate_jsonl_to_store()` 原样搬链（坏链拒绝、分叉拒绝、重跑幂
+  等）；JSONL 版保留读旧文件，新写一律走 Store 版。`kv_put` 不过
+  无凭证守卫（登记文档含用户 prompt，见 app_state.py 注释）。
+- 接线验证（本轨，本地）：P6 worker→P3 helper/authd→git 跑通真
+  PrivsepClient + 真 worker server + 真 git status（argv 含真实
+  helper 与 useHttpPath，argv/env/审计不含 token；runuser 与 HTTP
+  拉取留给真机）；P12 审批卡吃真实 P3 `ApprovalQueue.record()`、
+  权限登记吃真实 P5 `ScopedCapability.describe()`，均已用真实代码
+  跑通，不再用替身。
+- 未决与留给真机轨：① P11 冲突原样保留（档位门只做准入、USD 路径
+  不动，等用户裁决，见 `docs/chv-muse-p11-gap.md` §5）。② P8 客机
+  侧跟进未做（`chv-browser.py` 请求协议无任务 id 字段、进程拉起/
+  销毁须真机验证，见 `docs/chv-muse-p8-gap.md` §3）。③ 真机验证排
+  在 round-11 之后：P1 常驻/balloon/vsock、P2 §5 九项否定测试、
+  P3 §3.6 五项、P4/P5/P6/P7/P8/P9/P10/P11/P12 各自差距表 §6 清单、
+  以及本轨新增的迁移后真机表现（旧 JSON 一次导入、Store 审计链
+  在 VM 生命周期下的追加）。
+- 测试：新增 `cloud/tests/test_chv_muse_round12.py` 24 项全过；全量
+  cloud 套件在合入提交 5d5041b 上跑通：**2474 tests，OK
+  （skipped=9）**，404.8 秒，0 失败/错误（此前在 414e245 上两轮
+  2466 OK；2474 = 2466 + V-9 移植新增的 8 个运行）。ruff：迁移代码
+  做过 hygiene 清理（提交 414e245，import 排序 + 存储路径 except
+  收窄为 sqlite3.Error/OSError；transport 的宽捕获与仓内 % 格式风
+  格保留原样）；mypy 在 13 个集成改动源文件上只剩 4 处 06c3e17 基
+  线报错（marker_tools.py:142、executor.py:1573/1578），P9 的 5
+  处跨轨报错已随集成消失。
