+# 店铺密码按需读取
+
+## 使用方式
+
+现有管理员使用原财务账号密码登录，在“店铺账号密码”页面点击查看或复制。首版仅允许数据库中仍持有 `super_admin` 或 `admin` 角色，且拥有该页面访问范围的用户。每次请求重新查询角色，不信任旧权限缓存。普通用户和钉钉自动创建的普通账号不能读取密码。
+
+列表仍从 `database_4.external_store_accounts.accounts_v1` 的共享镜像读取。只有安全布尔字段 `passwordConfigured` 进入列表；镜像尚未新增该列时保持未知状态，管理员仍可按需请求，空密码由上游返回 404。镜像中的稳定账号 ID 是唯一请求目标，镜像未就绪时拒绝访问。
+
+查看在表格之外的独立弹窗中显示，30 秒、关闭、离开页面或隐藏标签页时清除；不写浏览器存储。复制单独请求 `purpose=copy`，成功后写入用户剪贴板，不自动清除剪贴板以免覆盖用户后续内容。每次操作独立读取，没有预取、批量读取、重试或密码缓存。表格和 CSV 只包含配置状态，不包含弹窗密码。
+
+## 后端与审计
+
+- 财务路由：`POST /{company_id}/store-account-passwords/{account}/reveal`，请求体仅允许 `purpose=view|copy` 和框架 CSRF 字段。
+- 使用可信会话中的用户 ID 生成 `requesterId=finance-user-{id}`，拒绝客户端额外提供操作者信息；验证公司、管理员角色、页面范围和镜像账号存在性。
+- 上游：`POST https://cp.jiansun.vip/internal/store-accounts/{id}/password/reveal`，专用 Bearer 令牌。完整契约来自上游 PR #17。
+- 专用 Guzzle 客户端不接入 Laravel HTTP 事件采集器，不记录请求、响应或异常对象。验证 TLS，总超时 10 秒、连接超时 3 秒，不跟随重定向、不重试，响应只缓存在本次请求内存中。
+- 上游 404/429 对应财务端 404/429；上游 403 表示服务凭据或网关配置故障，财务端返回固定 503 提示，避免误导为当前人员权限问题。上游 503、重定向、错误 JSON、缺少 `no-store` 或无效追踪 ID 均拒绝返回密码。财务权限拒绝为 403。
+- 财务端每用户 10 次/分钟；上游还按服务、人员、账号执行持久限流，查看和复制共享额度。
+- 新增 `store_account_password_audits`：只记录财务追踪 ID、操作者、公司、账号 ID、用途、状态、上游追踪 ID 和时间。开始审计失败不调用上游；成功审计无法落库时不向浏览器返回密码。审计成功表示服务器交付响应，不表示浏览器已经复制完成。
+- 响应 `Cache-Control: no-store`、`Pragma: no-cache`、`nosniff`、`no-referrer`。真实密码不进入日志、镜像、ClickHouse、Parquet、缓存或消息队列。网关/APM 必须排除该精确密码路由的请求/响应正文采集及响应落盘缓存。
+
+## 配置及发布
+
+后端环境变量为 `STORE_ACCOUNT_REVEAL_URL`（含 `{id}` 的完整 HTTPS 模板）和 `STORE_ACCOUNT_REVEAL_TOKEN`。令牌已在负责人提供的受保护文件中，不在文档或 PR 中复制。财务工作区已将两项配置保存到经 `git check-ignore` 核验的 `runtime/private/store-account-password.env`，仅供后端部署读取。
+
+上线需要单独批准以下范围：
+
+1. 备份生产系统库结构和当前应用配置；运行新增迁移 `2026_09_08_080000_create_store_account_password_audits`，只新增无密码审计表。
+2. 将上述两个变量安全加载到财务后端运行环境，禁止进入镜像、前端或发布输出。确认生产未启用响应正文采集。
+3. 如需显示上游新的布尔状态，按既有通用镜像登记/刷新流程更新该精确数据集的字段与镜像，核对 958 条资料仍完整。此步骤只涉及安全状态，不能加入密码字段。
+4. 使用已合并最新 main 及工作站发布脚本发布。生产验收需另行安排虚构上游账号，不能用真实店铺密码进行自动化抓取或截图。
+
+回滚使用上一应用镜像、移除新服务凭据即可；新增审计表保留，不自动删除审计或用户资料。不需要修改钉钉配置，也不需要新增管理员账号。
+
+## 验证
+
+18 项后端/镜像测试通过，覆盖管理员查看与复制、可信操作者、普通用户与受限管理员拒绝、镜像无账号、403/404/429/503/重定向、限流、缺失令牌、缺少 no-store、审计失败不返回密码，以及审计不含虚构密码。
+
+浏览器使用实际 Blade 渲染的虚构账号页面和独立本地假接口检查：查看、关闭清空、30 秒自动清空、复制后实际粘贴、桌面与 390px 窄屏弹窗。未调用上游真实店铺密码接口，未执行财务生产迁移或发布。
