feat(runtime)!: 退役 ctx.user 的 roles 别名,positions 成为唯一拼法 (#6011) (#6048)

ActorUser 同时声明并发出 `positions` 与 `roles`,两者由同一次赋值产生、值
逐字相同。`roles` 是 ADR-0090 D3 保留并禁用的词,且从未有关闭日期 —— 与
#5613 给 ctx.session 装上迁移窗口的同族面相比,这一面既无 spec 契约、也无
ADR-0087 台账条目、也无移除路径。维护者 2026-08-06 就地裁决:立即退役,
不设弃用窗口、不双发。

消费方核实(删除的前置条件,因为旧注释声称该别名 "kept for the REST/AI
shapes"):全仓 + objectui 扫描未见任何活体读取 `ActorUser.roles` 的代码。
四个生产点(action-execution / dispatcher-plugin / domains.actions /
domains.ai)构造的都是服务端 body / 路由处理器信封,不进入任何响应体;
objectui 的 `.roles` 读取全部落在 better-auth 会话与
`/api/v1/auth/me/permissions` 两个独立生产者上。

钉子同批翻转而非删除:三处断言改为既断言新语义的实质(`positions` 逐字
承载),又钉住方向(`roles` 键不存在)。反向验证已做:恢复被删的构造分支
后 7 条断言转红,方向与预期一致。

⛔ 不含 ctx.session:该面按 #5613 保留其弃用窗口,双发不动。
⛔ 不含 packages/spec:ADR-0087 台账条目另行落地。

+**BREAKING**: `ctx.user.roles` 已移除 —— action body / AI 路由处理器上的调用者位置(positions)只保留一个拼法 `ctx.user.positions`(#6011)
+
+`ActorUser`(action body 的 `ctx.user`、AI 路由处理器的 `req.user`)过去同时发出两个键,值完全相同(`roles` 是 `positions` 的逐字副本)。`roles` 是 ADR-0090 D3 明令保留并禁用的词,且没有关闭日期 —— 维护者 2026-08-06 裁定**立即退役**,不设弃用窗口、不双发。
+
+### 迁移:FROM → TO
+
+```js
+// FROM — v17 起该键不再存在,读到的是 undefined
+const positions = ctx.user.roles;
+if (ctx.user.roles.includes('sales_rep')) { … }
+
+// TO — 权威拼法,值逐字不变
+const positions = ctx.user.positions;
+if (ctx.user.positions.includes('sales_rep')) { … }
+```
+
+一行修复:把 body / 路由处理器里的 `ctx.user.roles` 改写成 `ctx.user.positions`(`req.user.roles` → `req.user.positions`)。**值不变** —— 两个键此前由同一次赋值产生,所以这是一次纯粹的改键,不是改语义。`positions` 数组恒存在,空时是 `[]` 而非 `undefined`,无需 `?? []`。
+
+### ⚠️ 改键不等于修好了权限判断
+
+`positions` 与此前的 `roles` 一样,**都不是授权输入**。权限由 security service 判定(capability 授予、placement、ADR-0095 推导出的 posture),不由名字字符串比较判定。因此:
+
+```js
+// 这不是迁移,这是把缺陷换了个拼法
+if (ctx.user.roles.includes('admin')) { … }      // 旧的错
+if (ctx.user.positions.includes('admin')) { … }  // 一样错,只是改了键名
+```
+
+把 `roles.includes('admin')` 改写成 `positions.includes('admin')` 迁移的是**缺陷本身**,不是那次读取。这类判断应改为向 security service 询问能力,而不是比对位置名。(与 #5991 的 `ctx.session` 更名同一告诫。)
+
+### 不受影响的面
+
+- **`ctx.session.roles` 不在本次范围内**,仍按 #5613 的弃用窗口双发 `positions` + `roles`,由 ADR-0087 语义迁移 `action-session-roles-to-positions` 约定其关闭时点。两个面同名不同物,请勿混为一谈。
+- better-auth 会话上的 `user.roles`、`/api/v1/auth/me/permissions` 返回体的 `roles`、CEL/formula 的 `current_user.*`,都是各自独立的生产者,均未改动。
