+- 管理员看得到服务账号和全部密钥，能给服务账号建密钥、撤销和轮换任何一把；
+- 每个人看得到自己的个人访问密钥；管理员打开开关（auth.personal_keys，缺省关）之后才能建；

+"""访问密钥（docs/design/next-round/04-对外集成与触达.md A1–A7）：签发、认人、门禁、限流、幂等、请求记录、接口说明。
+
+外部系统（门户、OA、BI）和个人脚本用一把访问密钥调接口：Authorization: Bearer agl_…。密钥是不记名的，泄露了就能被冒用，
+所以这一层的每个决定都往窄处取：
+- 签发（A1）：密钥格式 agl_ 加 32 字节随机串，只在创建、轮换时交回一次；库里只存 sha256 和开头一截（prefix，认是哪一把）。
+  到期必填（最长 365 天，缺省 90 天）；轮换是签一把新的、旧的 24 小时后到期，换钥匙不用停机；撤销立刻失效。拥有者是人
+  （个人访问密钥，管理员开关 auth.personal_keys 缺省关）或服务账号（users.kind=service，svc- 开头、没有口令、不能登录、
+  角色固定使用者，管理员建）。集成依附在某个员工身上，人一离职集成就断，所以有服务账号；开发自己写脚本拉数时不用找管理员，
+  所以有个人密钥——它暴露面更大，缺省关，管理员关掉开关时已有的个人密钥一并不认。
+- 认人（A2，authenticate）：中间件按哈希找密钥。找不到、到期、撤销、拥有者停用（或被删）、个人密钥开关关了，各回 401 带
+  各自的 code，绝不退回匿名、也不退回会话 cookie。认出来的身份一律封顶在使用者（A3，principal_for_key）：role=user、组是
+  拥有者现在的组、verified；不论拥有者是管理员还是搭建者——现有的使用者规则（只看得到授权的应用、最高到查看全部实例、工件
+  按白名单遮过、运行事件和实时流碰不到）全部自动生效，不另写一套「密钥能读什么」。
+- 门禁（A2，key_gate）：KEY_ROUTES 一张（方法, 路由模板）→ scope 的表，在 FastAPI(dependencies=[Depends(key_gate)]) 上挂一次，
+  按 request.scope['route'].path 比对路由模板（不在中间件里写正则：会和路由定义重复一遍，改路由时漏改）。不在表里的 403
+  key_route_forbidden；缺 scope 的 403 key_scope_missing；路径里的应用不在密钥限定的应用里 403 key_app_forbidden；个人应用、
+  只给拥有者的运行（个人应用的刷新、个人蓝图的试运行）一律 403 key_app_personal。同一张表生成接口说明（A7，reference），
+  说明和真实放行的接口出自一处，不会对不上。
+- 限流（take）：每把密钥每分钟 120 次，进程内令牌桶，超了 429 带 Retry-After。
+- 幂等（A4，once）：用密钥发起实例、刷新视图必须带 Idempotency-Key（外部系统超时重试一次就多出一个实例），按（拥有者, 键）
+  去重——轮换了密钥同一个键照样认得出；状态机和钩子共用（process/receipts.py）。
+- 请求记录（A6，note / flush）：哪一把、什么时候、哪个接口、回了什么、涉及哪次运行、从哪来。先在进程内攒着，调度循环每一拍
+  （或攒满 FLUSH_AT 条）批量写一次，保留 RETAIN 天；last_used_at 至少隔 1 分钟写一次——每个请求同步写一行会和运行抢 SQLite 的
+  写锁（同 sessions 的节流）。
+
+不限定来源 IP：服务端认的客户端地址是 request.client.host，在反向代理后面认不准，靠到期、撤销和请求记录兜底。限流、请求缓冲
+都在进程内，以单进程部署为前提（同登录失败退避）。

+"""用访问密钥用应用（docs/design/next-round/04-对外集成与触达.md A3–A6）：封顶在使用者、幂等、留痕、回复待办、视图数据、
+钩子的收件记录。
+
+- 封顶：管理员的密钥也按使用者算——取工件时查询快照是遮过的、节点产出 403；有「查看全部实例」授权的服务账号能列全部实例、
+  能下载报告，报告里遮罩的值写「已遮罩」；
+- 幂等：同一个 Idempotency-Key 发起两次只有一个实例；轮换密钥后同一个键照样去重；处理到一半服务停了，同一个键认领回已
+  发起的实例；不带键 400；同一个键办另一件事 422；有文件控件的入口 422；刷新视图同样要带键；
+- 留痕：run.origin 里有 via=key、key_id、密钥名（在清单哈希的封存范围内）；task.responded 记了 via；
+- 待办：个人密钥能回复审批、补充输入、编辑稿件；确认写入、双盲裁决、核实写入结果、工具审批 403（key_task_kind）；
+- 视图数据（agentlab.viewdata/1）：印章、清单哈希、指标原值；遮罩的 value 为 null、state 为 masked，和页面同一个判断；
+  按需视图没算过时 empty、不发起运行；改了页面布局形状不变；
+- 钩子收件记录：只有管理权限能读，列出状态和原因、近 1 小时验签失败次数。
