 ### 关键路径与数据
 
-- 应用/服务元数据：`<DesireCore根目录>/registry/official/entries/<entryId>/manifest.json`
-- 安装指南（docker-app）：`<同目录>/install.md`（含端口、docker compose 步骤、验证地址）
+- 当前目录快照解析：`POST http://127.0.0.1:<agent-service-port>/api/registry/acquisitions/resolve`
+- 机器消息解析与响应复核：`<本技能目录>/scripts/registry-catalog-acquisition.mjs`
 - 安装记录：`<DesireCore根目录>/config/installed-entries.json`
   （`<根目录>` 为你的 AgentFS 根，生产为 `~/.desirecore`，开发隔离为 `~/.desirecore-dev`，以自我感知里的实际根目录为准）
 - agent-service API：`http://127.0.0.1:<agent-service-port>`（端口见自我感知；mcp 服务安装/注册用）
 
+### 执行前协议：精确机器消息 → ownership / resolver（强制）
+
+任何 install/reinstall/uninstall 在环境探测、Docker 查询、包安装或其它执行类 `bash` 前，都必须
+先完成本节。自然语言只用于面向用户的说明，**不得**从自然语言猜测 `kind`、`sourceId`、
+`entryId`、deviceId、snapshot、install 或 connection。
+
+1. 从**当前这条**生命周期指令中提取唯一一行：
+   `RegistryCatalogAcquisition=<单行 JSON>`。App/Service envelope 都必须带
+   `operation:{action:"install"|"reinstall"|"uninstall",deviceId,operationId}`；operationId 必须是小写
+   UUID，并且只代表这一次 lifecycle 意图。先把指令全文交给
+   `parse-locator`，只取得 `sourceId+entryId+operation.deviceId` 的账本定位符；再用
+   `parse-message` 校验完整 envelope：
+
+   ```bash
+   node "<本技能目录>/scripts/registry-catalog-acquisition.mjs" parse-locator
+   node "<本技能目录>/scripts/registry-catalog-acquisition.mjs" parse-message
+   ```
+
+   完整解析结果为 `{request,locator}`；App resolver request 必须包含 operation。解析器会拒绝缺失、
+   重复、畸形机器行、额外字段、可变 commit、来源/snapshot 不一致和 App 夹带 install/connection。
+   不允许回看旧消息或从显示名、同 ID 本地条目、自然语言补字段。若 locator 已解析但完整解析
+   失败，先按“执行前停止的强制结算”处理；真正缺失/JSON 畸形且没有 locator 的手工指令不猜写
+   安装账本，只报告错误并停止。
+2. 对 App 三种 operation 及 Service install/reinstall，把解析结果的 `request` 原样作为 body 调 resolver：
+
+   ```yaml
+   tool: HttpRequest
+   parameters:
+     url: http://127.0.0.1:<agent-service-port>/api/registry/acquisitions/resolve
+     method: POST
+     body: <parse-message 输出的 request>
+   ```
+
+   install/reinstall 由服务端重验 current canonical；uninstall 由服务端按 operation.deviceId 精确读取
+   installed-entry 的不可变 lifecycle receipt，并用 receipt 对应的 Git object 返回旧版本定义。它不因
+   当前 catalog listing-only、stale 或下架而阻断，但无 receipt、receipt/snapshot 不一致、来源或设备
+   不匹配都失败关闭。
+   Service uninstall 不调用 current catalog resolver：它只按 locator 命中 exact installed receipt，随后
+   由精确 DELETE 端点使用 receipt.runtimeServerId 删除；目录删除、listing-only 或 stale 不得卡住卸载。
+3. 只有 HTTP 200 且响应通过同一脚本的 `evaluate-response` 复核后才可继续。复核
+   输入是 `{ "expected": <request>, "status": <HTTP状态>, "body": <响应JSON> }`。响应的
+   kind/sourceId/entryId/snapshot、manifest.id/type 必须一致，App 还必须取得非空 installGuide。
+   响应还必须包含服务端生成并校验的完整 `catalogReceipt` candidate。`allowed:true` 才是本次执行
+   定义；App 只使用其 manifest/installGuide/catalogReceipt，忽略任何 install/connection。uninstall 的
+   manifest/installGuide/receipt 必须来自服务端 receipt 解析结果，不能改读当前目录。
+4. 服务端有界拒绝码必须逐字保留：
+   `registry_acquisition_invalid_request`、`registry_acquisition_not_found`、
+   `registry_acquisition_snapshot_stale`、`registry_acquisition_blocked`、
+   `registry_acquisition_client_upgrade_required`、`registry_acquisition_config_mismatch`、
+   `registry_acquisition_install_guide_unavailable`、`registry_acquisition_receipt_missing`、
+   `registry_acquisition_ownership_mismatch`；同时保留通过有界校验的 reasons。任何非 200、
+   连接失败、非 JSON 或身份/快照/manifest 不一致都禁止执行命令，并先完成强制结算。
+5. **禁止 fallback**：不得读取任何本地 Registry 条目、改用同 ID 其它来源或沿用旧 resolver 响应。
+   resolver/ownership 只决定本次读取与精确归属，不新增安装账本，也不替代 Human Gate、健康校验、
+   回滚和终态收据。

 下文各流程的「回写安装记录」一律指这套统一方式，只标注目标 `status`。
 
 ### docker-app 安装流程
 
-1. **解析意图**：从指令提取 `action`（install/uninstall/start/stop/restart）、名称 → 映射到 `entryId`（查 registry entries 目录名 / manifest.id）、`type`（manifest.type），以及目标设备（缺省=本机）。若 `type` 为 `mcp`/`http-api`，改走下方"mcp / http-api 服务安装流程"。
-2. **读目录数据**：`read` manifest.json 拿到 `install.requirements`（docker/内存/磁盘/ports）与 `exposes`；`read` install.md 拿到部署步骤与验证地址。
-3. **环境校验**（`bash`）：`docker version` / `docker compose version` 确认 docker 就绪；用 manifest.ports 检查端口占用（`lsof -i :<port>` 或 `docker ps`）；磁盘空间。任一不满足→停下，向用户说明并给出修复建议，**不要**继续。
-4. **高风险确认**：安装/卸载会改动本机容器，属高风险。执行前用一句话向用户确认（应用名 + 目标设备 + 端口）。用户取消则中止。
-5. **执行**（`bash`，严格按 install.md）：
+1. **解析机器消息并调用 resolver**：严格执行“执行前协议”。action 与 deviceId 只认 operation；
+   `entryId`、`type`、版本、端口、exposes 和安装步骤只认复核后的服务端结果。manifest.type 不是
+   `docker-app` 时改走下方服务流程；身份或类型不一致立即停止。
+2. **读取本次授权定义**：从 resolver 返回的 manifest 读取 `install.requirements`（docker/内存/
+   磁盘/ports）与 exposes；只把 resolver 返回的 installGuide 作为部署步骤与验证地址。不得从
+   AgentFS 或其它目录补读/覆盖同 ID 定义。
+3. **环境校验**（`bash`）：`docker version` / `docker compose version` 确认 docker 就绪；用
+   `manifest.install.requirements.ports` 检查端口占用（`lsof -i :<port>` 或 `docker ps`）；检查磁盘
+   空间。任一不满足→先按 `pre_execution` 结算再停下，向用户说明并给出修复建议。
+4. **高风险确认**：安装/卸载会改动本机容器，属高风险。执行前用一句话向用户确认（应用名 +
+   目标设备 + 端口）。用户取消则按 `human_gate` 结算后中止。
+5. **执行**（`bash`，严格按 resolver 返回的 installGuide）：
    - docker-compose 类：在应用工作目录 `docker compose up -d`；docker 类：`docker run ...`。
    - 失败立即捕获输出，进入"失败处理"。
-6. **健康校验（先校验后回写，强制）**：按 install.md 的验证地址或 manifest.exposes 的 `http://localhost:<port><path>`，`bash` 用 `curl` 轮询（最多 ~2 分钟）确认服务可达。**只有这步通过才算安装成功**——不要仅凭 `docker compose up -d` 无报错就回写 `installed`。

 7. **回写安装记录**（**本技能的核心职责**，按上方「回写安装记录的统一方式」）：
-   - 健康校验通过 → PATCH `status: installed`；未通过/失败 → `status: failed`；重装失败但旧版本仍在运行 → 回 `installed`（见状态语义表）。
+   - 健康校验通过 → 用 `build-receipt-patch` 把 resolver 原样 candidate 与 `status: installed` 组成
+     CAS-safe PATCH，并携带 locator.operationId 和 candidate.releaseVersion；不得本地重建 receipt。
+     未通过/失败 → 首装 `status: failed`；重装失败但旧版本仍在运行 → 只 PATCH
+     `{sourceId,operationId,status:installed}`，不得附 receipt/version/pending（见状态语义表）。
    - 成功后无需手动派生服务——后端文件 watcher 检测到 `installed` 后自动派生；重装期间派生始终保留。
 8. **回报用户**：一句话总结结果 + 访问地址（成功）或失败原因 + 排查建议（失败）。
 
 ### docker-app 卸载流程
 
-1. 确认（高风险）。此时界面已把记录置 `uninstalling`（派生仍保留）。
-2. `bash`：进应用工作目录 `docker compose down -v`（或 `docker rm -f <容器>`），按需清理卷/镜像。
-3. 回写安装记录（按「回写安装记录的统一方式」）：
+1. 完整解析 App envelope 并调用 resolver。resolver 必须用 operation.deviceId 精确命中
+   sourceId+entryId+deviceId 的 `uninstalling` 记录，再按该记录的不可变 lifecycle receipt 读取旧 Git
+   object；**不得以当前 catalog eligibility 重新授权卸载**。同 ID 其它来源、其它设备、无 receipt
+   legacy 记录或 receipt/snapshot 不一致都拒绝。
+2. 只使用 resolver 从 receipt 返回并通过脚本复核的 manifest/installGuide 作为卸载定义；不得读取
+   当前 Registry 同 ID 条目补命令。resolver 拒绝时先结算回 `installed` 并提示手工管理/升级，不能
+   发明 compose 目录或容器名。取得定义后再做 Human Gate；取消即回 `installed`。
+3. `bash`：只按 receipt 绑定的 installGuide 执行卸载（如 `docker compose down -v`），按需清理
+   卷/镜像。
+4. 回写安装记录（按「回写安装记录的统一方式」）：
    - **成功**（容器确已停止/删除）→ PATCH `status: uninstalled`。后端 watcher 据此清理派生服务与 per-service Skill。
    - **失败**（容器未能停止/删除，应用仍在运行）→ PATCH `status: installed`，向用户说明卸载失败原因。**切勿**留在 `uninstalling`（界面卸载按钮会禁用，用户被卡住直至 stale 超时）。
-4. 回报用户。
+5. 回报用户。
 
 ### mcp / http-api 服务安装流程
 
 **mcp 服务**（manifest.type=`mcp`，条目含 `install` 与 `connection` 字段）：

-2. **读条目**：`read` manifest.json 拿 `install`（`method` npx/pip/uvx/docker/binary、`packageName`、`command`、`args`、`postInstall`）与 `connection`（transport/command/args/url/headers）。
+1. **解析机器消息并调用 resolver + 确认**：严格执行“执行前协议”，以复核后的复合身份确定
+   `entryId`，以 operation.deviceId 确定目标设备（mcp 通常装到本机）。resolver 失败时在任何安装命令前
+   停止；成功后再做高风险确认。界面已乐观写 `installing`/`reinstalling`。
+2. **使用本次授权定义**：只用 resolver 响应的 manifest/install/connection（`install` 含 method、
+   packageName、command、args、postInstall；`connection` 含 transport/command/args/url/headers）。
+   不读取或合并本地同 ID 条目。

 ### mcp / http-api 服务卸载流程
 
-1. 确认（高风险）。界面已置 `uninstalling`。
+1. 完整解析机器消息，但不调用 current catalog resolver。用脚本 `resolve-service-uninstall` 对 locator、
+   request.snapshot 和 `GET /api/installed-entries` 结果做完整复核：必须精确命中
+   sourceId+entryId+deviceId 的唯一 `uninstalling` 记录，receipt.kind 必须为 service，且
+   catalogReceipt.runtimeServerId 与 snapshot 必须有效。无 receipt/kind/runtimeServerId、身份/快照不符、
+   零条或多条都先结算回 `installed` 并停止。随后做高风险确认，取消同样结算回 `installed`。
 2. **执行卸载**（mcp）：从 Agent 移除 MCP server 配置：
    ```yaml
    tool: HttpRequest
    parameters:
-     url: http://127.0.0.1:<agent-service-port>/api/agents/desirecore/mcp-servers/<serverId>

      method: DELETE

+| resolver 200 但身份/快照/manifest/指南不一致 | 视为不可信响应，先强制结算，不执行任何生命周期副作用 |
+| resolver 200 缺失/篡改 catalogReceipt 或 App lifecycle guide 超过 64 KiB | 拒绝执行；禁止本地补建/截断 lifecycle，先强制结算 |
+| receipt PATCH CAS/runtime/lifecycle 冲突 | 禁止修改候选绕过；MCP 回滚注册后结算，App 按失败语义结算 |
+| operationId 缺失/畸形或旧消息重放 | 失败关闭；不得用当前 installed-entry 的新 operationId 替换旧消息，禁止执行或结算新意图 |
+| Human Gate 取消 | 首装回 `failed`，重装/卸载回 `installed`，不得遗留中间态 |
+| docker 未运行 | 提示用户启动 Docker；首装回 `failed`，重装回 `installed` |
 | 端口被占用 | 列出占用进程，建议换端口或停占用，征求用户意见 |
 | compose 启动失败 | `docker compose logs` 取错误，回写 `failed`，附日志摘要 |
 | 健康校验超时 | 提示"可能仍在启动"，给出查看日志的命令；如确认失败回写 `failed` |

 ### 边界与安全
 
-- 只装 registry 目录中存在的应用/服务；找不到 entryId 就明确告知，不要臆造安装命令。
+- 新安装只处理当前机器消息与 resolver 共同确认的应用/服务；卸载只处理精确 installed ownership。
+- `sourceId+entryId+snapshot+operation.deviceId+operation.operationId` 是本次边界；显示名、历史消息、本地同 ID 条目、
+  installed-entries 和调用方提供的 install/connection 都不能扩大它。
+- App resolver 必须先于 Docker 探测、包管理和所有执行类 `bash`；非 200 或复核失败没有 fallback，
+  并必须先结算中间态。uninstall 不受当前 catalog listing/stale 阻断，但只能使用精确 ownership 与
+  lifecycle receipt 解析出的旧版本定义。
 - 所有破坏性 docker 操作与 Agent 配置写入前必须有用户确认（risk_level: high）。
 - 回写状态优先用 PATCH 端点（自带 status 枚举校验与原子写）；仅端点不可用时降级 file-write，此时须自行保证结构合法（status 仅限六枚举值），否则界面加载会过滤掉脏条目。
 - **先校验后回写**：docker-app 必须健康校验通过、mcp 必须连接校验通过，才回写 `installed`——installed-entries 是「你校验过的事实」，不是「执行过命令」。
