+# YoVision 可选协调部署
+
+本目录只组合已经验收的 Sense、Brain、Bell 交付入口，不复制产品实现，也不成为业务事实源。三个产品仍使用独立包、进程、端口、数据目录、日志、数据库角色、账户空间、浏览器 Cookie 和机器身份。
+
+## 准备
+
+1. 将 `coordination.example.json` 复制到仓库外受控配置目录，填写三个已审核交付包的精确版本与绝对路径。
+2. 分别准备仓库外 `sense.env`、`brain.env`、`bell.env`。Sense 至少提供 `SENSE_DATABASE_URL`、`SENSE_JWT_SECRET`、`SENSE_PORT`，Bell 至少提供 `BELL_DATABASE_URL`、`BELL_JWT_SECRET`、`BELL_PORT`、`BELL_WEB_PORT`；其余配置（包括 connector 开关）仍遵循各产品自己的环境文件说明。不得在清单或仓库中填写密码、JWT、token 或私钥内容。
+3. 为每个调用实例创建独立 Ed25519 私钥和消费者公钥注册表；清单只引用私钥路径。
+4. 为 Sense、Bell 创建不同 PostgreSQL 数据库和角色；先使用各自迁移入口完成备份与迁移。
+5. 确认清单声明的所有端口、包目录、数据目录和日志目录互不重叠。
+
+编排器会创建并隔离清单中的数据、日志目录；各产品环境文件或产品配置还必须把自身持久化与业务日志指向对应目录。编排器不会猜测或改写产品内部配置。
+
+示例清单中的地址、版本和标识都是不可直接投产的占位值。默认 16 路只是当前交付配额，不是编排器容量上限。
+
+## 命令
+
+从仓库根目录运行；不需要修改 PowerShell 执行策略：
+
+```powershell
+pwsh -NoProfile -File scripts/runtime/coordination/start-yovision.ps1 -Manifest C:\YoVision\config\coordination.json -ValidateOnly
+pwsh -NoProfile -File scripts/runtime/coordination/start-yovision.ps1 -Manifest C:\YoVision\config\coordination.json -Product bell,sense,brain
+pwsh -NoProfile -File scripts/runtime/coordination/status-yovision.ps1 -Manifest C:\YoVision\config\coordination.json -Product all
+pwsh -NoProfile -File scripts/runtime/coordination/stop-yovision.ps1 -Manifest C:\YoVision\config\coordination.json -Product brain
+```
+
+`.bat` 包装器接受相同参数。启动时，`all` 只包含清单中 `enabled=true` 的产品；停止和查看状态时，`all` 会覆盖三个产品，避免产品被停用后遗留进程。启动顺序固定为 Bell → Sense → Brain，停止顺序固定为 Brain → Sense → Bell。单端失败只返回非零并清理该端新进程，不自动停止已经运行的其他端。
+
+## 状态与日志
+
+编排状态写入清单的 `runtime_root\state`，每端只保存 PID、启动时间、版本、命令路径和清单摘要，不保存环境变量值。协调启动日志分别写入各产品独立 `log_directory`。产品自己的日志仍由产品入口管理。
+
+`status` 返回 `running`、`unhealthy`、`stopped` 或 `stale`；仅当所选产品全部健康运行时退出码为 0。PID 与命令归属不匹配时不停止进程，必须人工核对。
+
+## 升级与回退
+
+升级顺序为：备份 Sense/Bell → 迁移 Bell → 启动/检查 Bell → 迁移 Sense → 启动/检查 Sense → 更新 Brain → 启用 connector。每次只替换一个独立包并更新清单版本。
+
+回退时先停用 Brain event export、Sense ingress/relay 与 Bell ingress/evidence connector，再按产品独立入口回退包或恢复各自数据库。不得删除 Sense Outbox、运行投影、Bell Receipt/Event、replay 或审计事实。根级编排故障时直接恢复三个产品原有独立入口。

+推荐启动顺序：完成两端迁移 → 启动 Bell ingress → 启动 Sense ingress/relay → 启用 Brain event_export。#152 的配置/状态 adapter 已有持久状态、重放与恢复接口，部署级 HTTP 托管和根级进程编排在 #154 统一绑定，不能用临时共享文件或数据库替代。
+
+回退时关闭 Brain `event_export.enabled`、Sense 两个 connector 开关和 Bell ingress/evidence 开关；保留 last-known-good、运行投影、InboundEvent、EvidenceRecord、Outbox、ReplayToken、Receipt、Event 与审计。不得删除事实、关闭 TLS/验签或改用网页登录态。

+## 三项目可选根级部署编排
+
+工单 #154 已于 2026-08-31 验收。根级编排只组合 Sense、Brain、Bell 已审核交付包，不复制产品实现，也不改变三端独立交付边界。事实入口如下：
+
+- 清单 Schema：`deploy/coordination/coordination.schema.json`
+- 无秘密示例：`deploy/coordination/coordination.example.json`
+- 操作说明：`deploy/coordination/README.md`
+- 启动、停止、状态入口：`scripts/runtime/coordination/{start,stop,status}-yovision.ps1`，并提供同名 BAT 包装器
+
+生产或验收环境必须先把示例清单复制到仓库外受控目录，并分别准备仓库外 Sense、Brain、Bell 环境文件和每实例独立私钥。Sense/Bell 使用不同数据库、数据库角色、账户空间、浏览器 origin、Cookie、JWT、端口、包、数据目录和日志目录；三端机器 principal、key id 和私钥文件也不得复用。清单只记录版本、路径和公开标识，不保存密码、JWT、token 或私钥内容。
+
+从仓库根目录使用：
+
+```powershell
+pwsh -NoProfile -File scripts/runtime/coordination/start-yovision.ps1 -Manifest C:\YoVision\config\coordination.json -ValidateOnly
+pwsh -NoProfile -File scripts/runtime/coordination/start-yovision.ps1 -Manifest C:\YoVision\config\coordination.json -Product bell,sense,brain
+pwsh -NoProfile -File scripts/runtime/coordination/status-yovision.ps1 -Manifest C:\YoVision\config\coordination.json -Product all
+pwsh -NoProfile -File scripts/runtime/coordination/stop-yovision.ps1 -Manifest C:\YoVision\config\coordination.json -Product brain
+```
+
+启动顺序为 Bell → Sense → Brain，停止顺序反向。启动时 `all` 只包含 `enabled=true` 的产品；停止和状态查询时 `all` 覆盖三端，避免停用配置后遗留进程。编排状态只保存 PID、版本、清单摘要和命令归属元数据；停止前必须核对 PID、启动器与命令令牌，归属不匹配时拒绝终止。单端启动失败只清理该端新进程，不自动停止其他端。
+
+升级时每次只替换一个独立包并更新精确版本，先备份 Sense/Bell，再按 Bell → Sense → Brain 验证，最后启用 connector。回退时先停用 Brain event export、Sense ingress/relay 与 Bell ingress/evidence connector，再使用各产品独立入口回退包或恢复数据库；不得删除 Outbox、Receipt、Event、运行投影、replay 或审计事实。16 路只是当前交付配额，不是编排器硬上限；真实生产包、PostgreSQL、客户 PKI、真机容量与长稳仍需部署环境验收。

+## 三项目协调 E2E 验收入口
+
+工单 #155 已于 2026-08-31 验收，并通过 PR #170 合入 `dev@0276bce`。该入口只用于隔离开发/验收，不是生产部署、生产迁移或现场容量测试：
+
+```powershell
+pwsh scripts/e2e/coordination/run-coordination-e2e.ps1
+```
+
+入口要求 PowerShell 7、冻结的 Go 1.26.5 工具链、Brain 可用 Python 环境、PostgreSQL 17 命令行工具，以及 Sense/Bell 各自独立 E2E 已记录的本机依赖。PostgreSQL 工具默认从 `D:\pgsql17\bin` 读取，可通过 `-PostgresBin` 指定其他安装目录；Python 默认优先使用 `Brain\.venv\Scripts\python.exe`，也可通过 `-Python` 指定。不得为通过测试而连接生产数据库、客户设备或生产服务。
+
+每次运行会在系统临时目录创建专属 PostgreSQL cluster，使用非 5432 动态 loopback 端口，并为 Sense、Bell 创建随机且不同的 database owner 和 database。测试凭据只存在于当前进程和临时测试范围，不进入仓库。入口按顺序执行冻结契约、三端 connector/持久化故障验证，并默认继续执行 Sense、Brain、Bell 各自已有的独立 E2E。
+
+`-SkipIndependentProductE2E` 只用于定位协调 harness 自身故障；使用该参数的结果不能作为 #155 或 MVP #156 验收证据。`-KeepTemporary` 只用于受控保留失败诊断，目录可能包含一次性测试数据，排查完成后按明确绝对路径清理，不得提交或共享。
+
+入口在 `finally` 中只停止自己启动的临时 PostgreSQL 和下游测试拥有的进程，核对端口关闭，并扫描临时日志是否出现本轮随机秘密。成功的最终判据是全部阶段退出码为 0，输出末行包含 `COORDINATION_E2E passed`，且 `git status --short` 没有产品源码或配置改动。
+
+该验收证明版本化契约、配置/状态、匿名事件、Sense Outbox、Bell Receipt/Event/Alert/ack/close、离线恢复、身份/重放/冲突/证据降级及三端独立运行；不证明真实 GPU/生产模型、真实摄像头、通知供应商、生产迁移、16 路长稳或客户现场效果。

+# Coordination E2E
+
+Run the complete isolated coordination acceptance from the repository root:
+
+```powershell
+pwsh scripts/e2e/coordination/run-coordination-e2e.ps1
+```
+
+The runner creates a temporary PostgreSQL cluster on a dynamic loopback port,
+uses distinct random owners and databases for Sense and Bell, exercises the
+frozen contracts and the three connector chains, runs each product's existing
+independent regression, checks generated secrets are absent from temporary
+logs, and removes only the processes and directory it created.
+
+`-SkipIndependentProductE2E` is intended only for local harness debugging and
+does not satisfy issue #155 acceptance. `-KeepTemporary` preserves disposable
+diagnostics after a failed run; the directory contains test-only generated
+credentials and must not be committed or shared.
