+# E签宝协议签署接入说明
+
+## 已实现范围
+
+- 五份原始文件使用独立类型和字段映射：`account-proof`、`account-change`、`entity-change`、`shared-contract`、`authorization`。
+- 每次发起先在 `business_courier_agreement_signatures` 落库，生成唯一 `business_no` 和 `idempotency_key`，再生成 PDF、上传文件并创建签署流程。
+- 保存 `fileId`、`signFlowId`、模板版本、原文哈希、签署文件哈希和完成证书哈希。
+- 回调复用现有 E签宝验签入口，校验原始 Body、时间戳、AppId 和 HmacSHA256；协议回调按流程 ID 幂等更新并排队归档。
+- 签署完成后只归档文件，不自动启用收款账户；账户、生效日期和收款人仍须财务复核。
+
+## 配置步骤
+
+在本地 `runtime/.env` 或受控部署环境中配置，禁止提交到 Git：
+
+```dotenv
+ESIGN_ENVIRONMENT=sandbox
+ESIGN_BASE_URL=https://smlopenapi.esign.cn
+ESIGN_APP_ID=替换为沙箱AppId
+ESIGN_APP_SECRET=替换为沙箱AppSecret
+ESIGN_NOTIFY_URL=https://你的公网域名/integrations/esign/callback
+ESIGN_CALLBACK_TOLERANCE_SECONDS=900
+ESIGN_TIMEOUT=20
+```
+
+正式环境单独使用 `https://openapi.esign.cn`、正式 AppId/AppSecret、独立 Webhook 和独立数据库记录。不要把沙箱凭证切换到生产域名，也不要在日志中输出 Secret、完整手机号、邮箱、身份证号或临时下载 URL。
+
+在 E签宝开放平台完成：企业认证、SaaS API V3 应用、出口 IP 白名单、Webhook、`SIGN_FLOW_COMPLETE` 订阅，以及短信/邮件和企业签署服务开通。
+
+## 联调步骤
+
+1. 在页面“协议签署 → 发起签章”选择文件类型，填写该类型专属字段和对方实名绑定的手机号/邮箱。
+2. 点击“推送至E签宝”，确认本地任务进入“待签署”，并记录任务的 `business_no`、`fileId`、`signFlowId`。
+3. 在沙箱签署页完成实名认证、签字或盖章；验证单页和多页文件的签章位置。
+4. 模拟或等待 `SIGN_FLOW_COMPLETE`：只有 `signFlowStatus=2` 才会下载已签 PDF 和完成证书。
+5. 检查任务变为“已签署并归档”，下载原文、已签协议和证书，核对哈希值。
+6. 不发回调时使用任务行的“同步状态”按钮验证主动查单补偿；重复点击推送或重复回调不得产生第二个 `signFlowId`。
+
+## 安全审计要点
+
+- 业务单号、文件 ID、流程 ID 分开保存；发起前有唯一键，超时后不得直接重发。
+- 回调使用恒定时间比较和时间戳窗口，先验签再解析；回调状态不能把已完成状态回退为处理中。
+- 原文和归档文件存私有 `uploads` 盘并校验 SHA-256；临时下载地址只在服务端短时使用。
+- 个人证件和账号字段采用加密 cast 存储；权限仅允许管理员发起、同步和下载。
+- 企业名称不能作为模糊账号匹配依据；应在 E签宝实名账号确认后填写手机号/邮箱。
+- 电子签署完成不等于财务数据生效，收款账户变更必须保留人工复核和原档案电话核验。
+
+## 真实环境上线前
+
+- 使用密钥管理系统或受控环境变量保存正式 Secret，并完成轮换/吊销流程。
+- 配置公网 HTTPS、出口 IP 白名单和回调来源 IP 白名单。
+- 为签章坐标、个人/企业签署、拒签/撤销/过期、下载 URL 过期和回调丢失分别留存验收记录。
