+`POST /learning-plans` 为当前已认证、有效且未封禁的用户保存已确认的学习计划。请求必须携带规范 UUID 格式的 `Idempotency-Key`，且来源提交必须属于当前用户。相同 key 和请求内容重试时返回原记录；同一 key 携带不同内容时返回 HTTP 409（业务码 `40900`）。`GET /learning-plans/{id}` 和 `GET /learning-plans/by-key/{key}` 仅返回当前用户拥有的记录。

 浏览器通常通过前端 Nginx/gateway 访问 `/api`；不要把内部 Dubbo、数据库、Redis、Nacos 或 worker 端口发布到公网。
 
 浏览器侧统一经 `packages/http-client` 发起调用，成功结果只暴露业务 payload：`Result.code` 为 0 返回 `data`，非 0 以 `ApiError` 拒绝，非 `Result` envelope 返回 payload 本身（含 Blob），不提供原始 transport response。`apiDownload` 返回 `Promise<void>`，以 object URL 与临时 `<a download>` 元素触发浏览器保存；URL 创建后无论 DOM 步骤成功与否都会移除元素并 revoke URL，清理失败不覆盖原始错误。

+- `e2e_boundary_evaluation.py` runs the real model over the six synthetic boundary
+  categories — `missing_id`, `no_tool`, `no_hit`, `tool_failure`, `source_injection`,
+  `wrong_citation` — and fails closed when the citation gate rejects an emitted citation,
+  when a behaviour misses, or when a forged or unsupported negative control is not rejected.

+`Runtime Error` is the classifier's catch-all branch; by itself it names no specific cause.
+A judging status is an observed fact; any explanation of why it occurred is a hypothesis that needs further evidence.
