 待办、历史和处理结果使用统一、精简的领域字段，不向 Agent 暴露钉钉任务 ID、薪福通员工号或上游原始响应。历史查询分为 `handled`（本人已经处理过）和 `submitted`（本人发起），结果没有 `selectionId` 和可执行动作。常见 `approvalId` 使用紧凑的 v4 无状态加密格式：薪福通通常约 60 字符、钉钉 OA 通常约 100 字符，并绑定当前用户和 30 分钟有效期；历史引用还绑定查询语义，只能读取详情。旧版未过期的 v2/v3 引用仍可读取。

+薪福通消息中心返回且带稳定任务标识的本人待办都会进入列表。原有费用单据以及能被正式单据接口实时识别的新类型继续支持详情、同意、拒绝和退回；尚未确认接口兼容性的项目返回空 `availableActions` 与 `manualAction.reason=unsupported_xft_task_type`，只允许引导到薪福通客户端查看和处理。此类引用读取详情不会请求未验证的上游接口，动作查询全部返回禁用，批处理在预检阶段以 `provider_not_supported`、`writesStarted=false` 整批零写入；列表包含此类项目时不签发 `selectionId`。新增的能力诊断只给出数量，不额外携带任务 ID、单号、人员或正文。
+
 一次写调用最多处理 20 条。整组同意/拒绝可直接使用 `selectionId`；超过 20 条时，Agent 可从同一次原始列表中按 `approvalId` 分组，不需要 `batchPlan`，也不能重新拉取后把新待办混入原授权。服务器在首个写入前校验整批 `approvalId` 和 `targetId`；任一引用无效时返回 `preflight_failed`、`writesStarted=false`，整批零写入且不自动补偿或重试。普通文本与结构化结果保持同一份精简数据，以兼容不渲染 `structuredContent` 的宿主。

 Agent 不传 `userId`、员工号或单据所有者。网关从 OAuth Token 确定用户，再分别映射钉钉 OA 与薪福通身份。钉钉提单中的申请人和部门也由网关通过当前登录用户的通讯录档案实时填写；即使用户修改本地桥，也不能冒用他人身份或部门。

 用户不需要理解薪福通的任何内部选择值。实时 Schema 会把部门、城市、费用类型、出行方式、往返、时间范围、币种和酒店星级等字段标记为名称优先的选择项；Agent 只展示“深圳市”“交通费”“飞机”“往返”“人民币”等业务名称，选定后仅在内部写入正式接口值。动态下拉框也会标准化成 `label/code`，表格子字段同样递归处理。准备阶段的最终确认预览会再次按实时选项反向解析，只返回业务字段名和业务名称，不回显城市码、费用编码、字段号或表格列号；任何值无法可靠反向解析时，不生成 `confirmationId`。无法取得可靠名称映射时安全停止或允许跳过可选项，不退化为向用户索取工号、城市码、组织码、档案编号、数字舱位值或其他内部 ID。

+薪福通正式 OpenAPI 当前没有独立的费用类型目录查询。费用类型会先从模板实时字段读取，再检查企业自定义多级数据源；两处都没有可用选项时，MCP 返回具体的实时检查结果并引导在费用管理页面确认或使用薪福通客户端，不会把空目录误报为网络 `fetch` 故障。
+
 人员、企业自定义档案、关联前置单据、分摊及文档未给出可靠名称映射的舱位字段目前标记为 `client_only`。必填时不生成提交预览并引导薪福通客户端；可选时不会作为普通问题打扰用户。单据公司、部门、字段引用和行程序号等服务器管理或内部派生值也不会作为用户输入项展示。

 服务端临时保留不可逆的用户/发票 HMAC 指纹。首次使用时只为最近 30 天尚未索引的审批读取详情；以后准备提单会刷新精简历史状态，并只为新增审批补建指纹，不会重复逐张下载已索引发票。指纹和最小审批索引最多保留 35 天，过期后自动级联删除；10 分钟提单预留到期即删除。

 Agent 面向统一审批语义，不直接理解钉钉 `processInstanceId/taskId`、薪福通员工号、上游响应或完整 Schema。网关在内部完成来源路由、字段抽取、动作调用和写后复核，只返回审批判断所需的精简字段与统一状态。

+薪福通当前待办以消息中心的本人任务为可见性边界，不再用应用码或单据类型白名单过滤。对旧费用类型以及能被正式 `bill-list` 实时识别的未知应用任务，网关标记为 `bill_api` 并沿用详情和审批链路；其他带稳定任务标识的项目标记为 `list_only`，只返回安全列表字段、空动作集合和客户端处理提示。`list_only` 的上游任务标识只进入用户绑定、来源绑定且短期有效的 v4 加密引用，不作为业务编号展示；详情和动作查询不会触发未经确认的上游接口，写请求在整批预检阶段返回 `provider_not_supported` 且零写入。包含此类项目的结果不签发 `selectionId`，诊断仅汇总 `billApiCount/clientOnlyCount`。本次能力分级只作用于当前待办，已处理历史仍只读取正式单据接口可验证的记录。
+
 薪福通所有选择字段按领域选项抽象。部门、城市和费用类型由选项工具返回精简 `label/code` 映射；模板内嵌下拉框被标准化成同样结构，固定枚举通过 `enumLabels` 提供中文名称，表格子字段递归应用相同规则。Agent 只把业务名称展示给用户，正式值仅用于内部构造请求。准备确认时，网关再用实时 Schema 把正式值反向解析为业务名称；预览不包含城市码、费用编码、自定义字段号或表格列号，任一选择无法反向解析时会在签发确认引用前安全失败。无法取得可靠名称映射的人员、档案、关联单据、分摊和部分舱位字段标记为 `client_only`，必填时安全停止、可选时允许省略，绝不转而索取工号或编码。用车申请已从 MCP 发起范围移除，实时模板列表会过滤，旧模板引用也会被网关拒绝。响应不包含完整数据源、内部身份或其他企业档案，选项目录也不持久化。

 所有工具以普通 `content.text` 中的精简 JSON 作为跨宿主可见结果，同时保留相同的精简 `structuredContent` 供支持结构化结果的宿主使用；两处都不携带诊断字段或上游原始响应。`raw` 仍是受过滤、分页和硬限额保护的按需诊断视图，不是默认数据通道。

 薪福通自定义字段在工具内部统一使用 `customFieldValues[].fieldNumber/fieldValue`，但用户不应看到或提供这些引用。日期字段使用 `yyyy-MM-dd HH:mm`；部门由可读名称选择后内部映射；下拉框与表格子字段使用实时名称映射。人员、附件及其他没有安全名称查询或上传能力的字段标记为 `client_only`，不会要求用户填写花名册编号或附件编号。`approval_get_submission_schema` 会返回实时 `valueFormat`、`selectionCapability` 和该模板的精简 `minimalExample`；后者只说明 `values` 形状，所有尖括号占位符都必须由用户业务回答或实时选项替换，不能原样提交。Agent 不得按字段名称猜编码或结构。

-薪福通模板要求承担部门、城市或费用类型时，使用同一 `templateId` 调用 `approval_get_submission_options`。`kind=department` 只会返回当前登录用户本人档案中的可选组织；`kind=city` 可用 `query` 按城市名称搜索；`kind=expense_type` 先读取模板内嵌选项，再按需读取企业多级费用类型数据源。费用申请、差旅预计费用及报销明细均标记对应选项源。固定枚举提供 `enumLabels`，例如出行方式、单程/往返、上午/下午、人民币和酒店星级；动态 `SELECT` 的 `options` 统一为 `{label, code}`，表格列也递归标准化。Agent 只向用户显示名称并在内部使用正式值，不得向用户索取内部编码。`approval_prepare_submission` 会对标准字段、自定义下拉和表格列做第二次反向解析，确认预览只保留业务名称；无法映射时不签发确认引用。城市全量接口较慢，网关给予独立的 45 秒超时并在进程内缓存字典 24 小时，不写入磁盘；费用类型保持实时且不落盘。响应不会暴露员工号、完整数据源或原始成员档案。

 薪福通的自定义字段接口可能同时列出标准单据抬头控件，也可能用动态字段号返回名为“承担部门/单据部门”的控件，但创建接口禁止把这些标准控件放进 `customFieldValues`。MCP 会剔除服务器管理控件并拒绝调用方显式指定公司或部门；两者省略时由薪福通根据当前登录申请人的档案默认填写。真正的业务部门选择字段则只展示当前用户可用的部门名称并在内部映射。
