 - **白名单管理 (Login Whitelist, admin-only)**: gates **who may log in**, run as a **blocklist (黑名单模式)**. Two pieces: a global master switch (`system_settings.json → login_whitelist.enabled`, surfaced by **admin-only** `GET|PUT /api/system-settings/login-whitelist`) + a per-user **放行** flag (`users.approved` column, migration `20260625_02`). Users **self-register** as usual and **every new account defaults to `approved=True`** — so a user who has never logged into this system before is allowed straight through; the switch only blocks users an admin has explicitly **取消放行** (`approved=False`). (`create_user`/`User`/`UserRow` all default `approved=True`; admins are always approved; existing rows are backfilled `True`.) Login interception is the single helper `enforce_user_approved(user)` in `app/gateway/routers/auth.py`, called in all three login endpoints (`/login/{local,username,token}`) **after** the account is resolved/created and **before** the JWT is issued: switch off → everyone passes; `system_role=="admin"` → always passes (anti-lockout); else `approved=False` (admin-revoked) → 403 `{code:"PENDING_APPROVAL"}` (the frontend's `extractErrorMessage` surfaces the message and login throws before writing any auth state, so no half-login). Admin approves on `pages/LoginWhitelistPage.tsx` (route `/page/strategy/admin/login-whitelist`, entry「白名单管理」in the bottom-left settings dropdown of `components/page-sidebar.tsx`, both sidebar modes): a top master-switch + a list of all registered users (`GET /api/v1/auth/users`, now carrying `approved`) with a per-row 放行 Switch (`PUT /api/v1/auth/users/{id}/approval`, admin-only; revoking only blocks the **next** login — `token_version` is left untouched, existing sessions are not force-killed). Client/hooks: switch in `strategy-components/api/login-whitelist.ts`, user list + approval in `core/auth/{api,hooks}.ts` (`useSetUserApproval`). Backend tests: `tests/test_login_approval.py`. **账号级「登录口令」(per-account password — 临时开通)**: the same page also lets an admin assign one specific account an individual **plaintext** password (`users.login_password` column, migration `20260625_04`, nullable; auto-added on startup by `_ensure_orm_columns_sync`). Once set, **that account's** username login (`POST /api/v1/auth/login/username`) **requires** `?password=` to exactly match it and that personal password **takes precedence over** the global shared-password gate (`username_login.require_password`); accounts without one keep today's shared-gate / passwordless behavior. The user then logs in via the **existing** frontend URL `#/login/<用户名>?password=xxxx` (LoginPage already forwards `?password=`; `<用户名>` = the account's email `@`-prefix). **Plaintext is intentional** — the password rides in the URL query anyway, so storing it readably lets the admin re-copy the full login link from the page; it is exposed only on the **admin-only** `GET /api/v1/auth/users` (`UserListItem.login_password`) and the new admin-only `PUT /api/v1/auth/users/{id}/login-password` (set non-empty / clear with null·empty; doesn't touch `token_version`). The whitelist page renders a per-user 「登录口令」 column with a set/修改 editor + a live 「复制登录链接」 button (`useSetUserLoginPassword` in `core/auth/hooks.ts`, `setUserLoginPassword` in `core/auth/api.ts`). Backend gate helper `_lookup_user_by_username` (lookup-only, no auto-register) in `routers/auth.py`; tests `tests/test_login_personal_password.py`.

Page `TaskButtonsPage.tsx` (route `/page/strategy/admin/task-buttons`, **admin-gated**, entry「按钮管理」in the bottom-left settings dropdown of `components/page-sidebar.tsx`, both full + collapsed modes) has per-business tabs, edits name/type/target/启停/排序/增删, saves the **whole set atomically** (replace-all), plus 「导入默认」 to merge code-seed defaults. **Seed/fallback** (like 敏感词管理): only when the whole table is empty (fresh deploy, never saved) do the workspace + page fall back to `defaultTaskButtons(cfg)` — rwfx's url buttons (编辑/上一步/下一步/3q详情) built from the **live** `/api/public/config/task-deeplink` plus cross-business switch buttons for **all three** businesses (each switches to the other two — rwfx→三情/行动, 3qfx→任务/行动, xdfx→任务/三情). Once saved, the store is the sole source of truth. **Bottom 快捷跳转 bar groups by prev/next**: `TaskJumpBar` renders only「上一步/下一步」-type buttons in the bottom bar — a `prev` group (id 含 `prev` 或文案「上一步」, 描边次要样式 + ←图标) rendered **左侧**, then a `next` group (id 含 `next` 或文案「下一步」, 实心主色) on the **右侧** (container `justify-end`); everything else goes to the right-edge floating menu. The default 上一步 button (`rwfx-prev`, `url`, target = `DASHBOARD_AGENT_ROUTE` `/page/strategy/dashboard-agent`, `appendTaskId` + `idParam=taskId` → `?taskId=任务id`, `openMode=self`) 默认指向**应用内**「大屏绘制」Line truncated
 - **实时并发监控 (Concurrency / System-Pressure Monitor, admin-only)**: a live panel mounted at the **top of the admin 排行榜 page** (`components/workspace/admin/concurrency-monitor.tsx` `ConcurrencyMonitorPanel`, rendered in `pages/AdminUserLeaderboardPage.tsx`) showing **当前并发的大模型调用数 + 列表（用户/智能体/类型/已运行时长）**, each row with a 「停止」button (and a 「全部停止」) that **truly aborts** that run's in-flight model stream via `RunManager.cancel` (`POST /api/admin/active-runs/{run_id}/cancel`) — to relieve pressure when 使用人数过多. Two line charts (minute/hour toggle): **并发量折线图** (peak/avg, `GET /api/admin/active-runs/concurrency`, fed by a lightweight background sampler into `concurrency_samples`) and **大模型出字速度折线图** (tokens/sec, `GET /api/admin/active-runs/token-speed`, aggregated from `llm_call_metrics`) so a dip pinpoints where the bottleneck is. A **「后台采样」Switch** (`system_settings.json → concurrency_monitor.enabled`, **default off / opt-in**, `GET|PUT /api/admin/active-runs/settings`) turns the background sampling on/off **at runtime, no restart** (the live concurrency count + 「停止」 work even while sampling is off — only the 并发量 history chart needs it on); everything is designed to **never impact production** (one tiny INSERT/15s, retention-purged, best-effort). Client/hooks: `core/admin/active-runs.ts` + `core/admin/hooks.ts` (`useActiveRuns`/`useConcurrencySeries`/`useTokenSpeedSeries`/`useCancel*`/`useMonitorSettings`). See the backend CLAUDE.md「Admin Concurrency Monitor」.
 - **会话冲突 409 中文化**: when a user submits a new question while the previous turn is still streaming, the backend's `RunManager.create_or_reject` rejects with HTTP 409 (`services.py` now returns a **Chinese** detail「当前对话还在生成回答…」). `core/threads/hooks.ts` `onError` detects the conflict (`isActiveRunConflictError`: 409 / "already has an active run" / the Chinese text) and shows a friendly `toast.info` instead of a raw error.
 - **State**: TanStack Query for server state, context providers (`SubtasksProvider`, `ArtifactsProvider`, `PromptInputProvider`) scoped to `WorkspaceRoutes`

Resolving by current login meant account B opening a shared task conversation 404'd on the md/artifacts account A generated ("切换账号后生成的文件找不到"). `deerflow/runtime/thread_paths.py` (`resolve_path_user_id` sync / `aresolve_path_user_id` async) resolves a task-shared thread to its **creator** (`threads_meta.user_id`), so every account reads/writes the same physical directory; personal threads resolve to the current login unchanged (no behavior change). Wired at every thread-path seam: write source `ThreadDataMiddleware.before_agent` (drives all sandbox writes via `thread_data` paths), `present_file_tool`, `uploads/manager.get_uploads_dir` + `uploads_middleware` + uploads router, artifact serving (`path_utils.{a,}resolve_thread_virtual_path` → artifacts/skills routers), embedded `client.get_artifact`. Positive (taskId→creator) results are cached process-wide (immutable mapping); any failure / memory-mode store / missing row falls back to the current login. **Caveat**: files a *non-creator* wrote into a shared thread before this fix stay orphaned under that writer's dir (no data loss); all new writes consolidate under the creator. **Extended to 圆桌会商 system threads** (`metadata.thread_type == "roundtable"` — Step 2 seats/coordinator + Step 3 report/summary/dashboard/structure, created by `multi_agent.py` with `_ROUNDTABLE_THREAD_METADATA`): their Step2/Step3 sandbox artifacts (md/流程图/报告) must stay viewable when a历史草稿 is reopened or a taskId会商 draft is opened by another account, so `thread_paths._is_creator_shared_thread(metadata)` treats both `taskId` **and** `thread_type=="roundtable"` as creator-shared, and `ThreadMetaRepository.check_access` (the artifacts router's `owner_check`) bypasses the owner filter for both — roundtable thread ids are only surfaced inside the owner's draft, so this does not let unrelated accounts *discover* others' 会商 files. Tests: `tests/test_thread_paths_owner.py`, `tests/test_thread_paths_roundtable.py`.
+- **`{user_id}` for path resolution = `resolve_path_user_id(thread_id)`, using the persisted creator for every tracked thread.** The route's regular owner check still authorizes access first; creator resolution only selects the stable physical directory (`threads_meta.user_id`) and avoids a lost request context falling back to `users/default`. This also preserves cross-account task-deeplink conversations (rwfx/3qfx/xdfx) and roundtable system threads. Positive creator mappings are cached process-wide and DB/memory/missing-row failures fall back to the current login. It is wired at the thread-path consumers including `ThreadDataMiddleware.before_agent`, `present_file_tool`, uploads, artifact serving, and embedded `client.get_artifact`. **Rewrite-history recovery is metadata-only and job-owner scoped** (`list_by_session(..., user_id=current_user)`), so its GET/list endpoints intentionally skip redundant thread-owner checks and return an empty history instead of a history-only 404; the start/commit endpoints retain strict thread write authorization. Tests: `tests/test_thread_paths_owner.py`, `tests/test_thread_paths_roundtable.py`.
+
+- **Durable document-rewrite commit:** `document_rewrite_pipeline.atomic_write_text` writes through a deliberately short sibling temporary filename so long Windows artifact paths stay below the path-length limit, and guarantees the target `outputs` parent exists. If the sandbox recreates that directory in the narrow commit window, it repairs the directory and retries; the original file is otherwise only changed through `os.replace`.
+
+- **Deep Research structural regeneration:** `POST /api/deep-research/sessions/{id}/report-variants` creates a distinct completed session from the source report and its selected evidence. It rebases both saved `[来源：source_id]` and legacy streamed `[[source:source_id]]` markers to cloned ids, and removes inherited markers with no selected clone. The frontend uses this endpoint only for “选择结构再生成”, then queues the durable writer with `operation=generate`; generation receives the confirmed outline and complete selected evidence set but never receives the inherited report as text to edit. The new report's completed card can subsequently start a separate in-place `AI 全文改写`. Requirement plans are deterministic and operation-specific, model reasoning is forwarded as live SSE before the first Markdown token, and generation prompts emit display-ready `[来源：id]` citations. Citation validation repairs only a unique near-complete `drs_src_*` prefix (provider-truncated suffix) and still rejects genuinely unknown ids. The report-only stream requests 8192 output tokens (except Codex Responses models, which reject token-limit kwargs) and rejects a malformed trailing citation instead of committing a provider-truncated report. Never restore the former second planning-model call unless its latency and streaming contract are redesigned together.

-The independent enterprise-research workbench (`/api/enterprise-research/tasks`) is deliberately separate from `/api/deep-research`: it stores an owner-scoped task plus a bounded, deduplicated evidence snapshot in `enterprise_research_tasks`, then calls WeKnora through the existing DeerFlow LLMWiki mapping and visibility checks. Never expose remote WeKnora IDs or credentials to its browser API, and do not make this workbench mutate a knowledge base or an existing Deep Research session/report. After collection, its plan endpoints can save an editable Markdown outline and an explicitly selected source subset; validate every selected chunk ID against the saved snapshot. The AI-plan variant may call a configured DeerFlow model but must not retrieve new evidence. `enterprise_research_report_jobs` freezes that plan/source subset plus action/model/style/length and before-image before calling the shared `DeerFlowCompletionBackend`, so the writer cannot run a fresh uncontrolled retrieval or accidentally use later task edits. Actions are `initial`, `rewrite`, and report-only `followup`; only successful initial/rewrite jobs may replace the task report. Its SSE route sends the persisted draft first and then only live `report_delta`/`reasoning_delta` events; reasoning must never be appended to report Markdown. Active rows carry a nullable owner/task dedupe key with a database unique constraint; terminal transitions clear it so history remains unlimited while simultaneous workers cannot create two active jobs for one task. Startup recovery must requeue the exact previously-read running snapshot and then use an atomic queued→running claim. Cancellation, completion, and failure are conditional state transitions so cross-process races cannot turn cancelled work into a committed report. Restore only accepts a completed rewrite before-image, rejects active jobs, and writes a new reversible history row before changing the task. The persistence contract is `deerflow.persistence.enterprise_research`; large evidence/report payloads use `PortableLongText` because MySQL `TEXT` cannot safely hold them.

 - **Conditional WeKnora LLMWiki**: a non-empty `llmwiki.weknora.api_base_url` enables the DeerFlow-native WeKnora BFF and UI; an empty address preserves the existing LLMWiki page. WeKnora remains independently deployed and owns its database, Redis, storage, parsers and models. DeerFlow keeps only the API/admin addresses, user/publication mappings, agent knowledge-base bindings and per-conversation selections; it stores and sends no WeKnora credential, so the endpoint must be restricted to a trusted network and allow DeerFlow traffic. Owners publish directly to the public LLMWiki without an approval queue for ordinary bases; the system-owned conversation-deposit base is always published, shared by all users, excluded from My Knowledge, immutable through user/admin detail operations, and recognized by both its reserved name and `system` owner. An existing same-name remote mapping is adopted in place as the system deposit so its mapping id and document links stay valid. Its user-facing knowledge-base description and generated document metadata use the `cmzs` brand; list/detail reads synchronize stale remote descriptions, while conversation-deposit search results, source previews and embedded-detail JSON rewrite legacy brand text to `cmzs`. Deposit requests must reference a thread accessible to the current account. Personal knowledge-base lists are scoped to the current DeerFlow account even for admins, while frontend LLMWiki query caches also include the active account id so switching accounts cannot reuse another account's list/detail data. Admins remain the only role that sees the WeKnora connection-config tab. Knowledge cards open a dedicated WeKnora-style detail route: Wiki-enabled bases default to Wiki, then documents and graph; standard bases hide Wiki and default to documents. Writable ordinary knowledge-base details expose a native multi-file upload action that submits files sequentially and reports aggregate success/failure; read-only public bases and the system deposit base do not. It supports file/URL/manual-Markdown imports, Wiki page browsing, document preview, real parsed chunks and Wiki graph nodes/edges. New chats use a compact WeKnora-style searchable/grouped multi-select inside the composer, while agent create/edit pages bind spaces through an inline panel. A single proxy service identity means DeerFlow users are isolated logically while their WeKnora entities share that identity's workspace. The read-only `llmwiki_search` tool reauthorizes the current DeerFlow user on every call and renders credential-free source previews; source previews prefer cleaned Wiki/LLMWiki text when a retrieved chunk maps to a Wiki page, with raw chunks as the fallback. The detail page first creates a signed iframe session through the normal DeerFlow API auth path, then points the iframe directly at the proxied WeKnora `/platform/...` route using the signed `deerflow_weknora_embed` cookie; global auth/CSRF bypass is limited to those signed iframe proxy requests, and HTTPS cookie attributes honor `X-Forwarded-Proto` behind reverse proxies. The iframe proxy keeps WeKnora's root-relative `/platform`, `/assets`, `/locales`, and `/api/v1/*` paths, but is registered last through `llmwiki.proxy_router` so it cannot intercept first-party Gateway APIs such as `POST /api/v1/auth/login/username`. See [docs/LLMWIKI_WEKNORA_INTEGRATION_ZH.md](docs/LLMWIKI_WEKNORA_INTEGRATION_ZH.md).
-- **Enterprise Research workbench**: `/api/enterprise-research/tasks` is an independent, user-scoped evidence workbench; it never enters or changes `/api/deep-research`. DeerFlow persists each task's topic, generated queries, selected DeerFlow knowledge-base mapping IDs, collection state, and a bounded/deduplicated WeKnora evidence snapshot. Collection reuses the LLMWiki BFF's mapping-based authorization, so browsers never send a remote WeKnora ID or credential and can retrieve only sources in their own or published knowledge bases. Once collection finishes, the task can persist an editable Markdown research plan and a validated subset of its snapshot sources; the optional AI-plan endpoint improves that outline with a selected DeerFlow model without retrieving new material. Persistent `report-jobs` support initial writing, full-report rewrite, and report-only follow-up. Each job freezes its plan, source subset, model/style/length controls and before-image, streams Markdown/reasoning through DeerFlow's standard model adapter, persists the latest draft for reconnect, and commits only a successful non-follow-up report back to the owning task. Startup recovery uses compare-and-set requeue/claim, while cancellation and completion are conditional transitions so another process cannot overwrite a cancelled job. Markdown/Word delivery, clickable evidence citations, before/after comparison and reversible rewrite versions are served from the same task history without modifying an existing Deep Research report.
+- **Enterprise Research workbench (temporarily disabled)**: the independent `/api/enterprise-research` router, its report executor, and its ORM table registration are intentionally inactive. The implementation remains in the repository, but startup does not create or alter `enterprise_research_tasks` or `enterprise_research_report_jobs`; this keeps the active Deep Research workflow independent of the paused workbench and avoids MySQL schema errors.
 - **Embedded WeKnora detail chrome**: the proxy hides WeKnora's application sidebar (`.main > .aside_box`) and expands the detail outlet to the full iframe width, while preserving the Wiki page's own index/navigation panel.
 - **Embedded WeKnora knowledge-base switching**: the original breadcrumb picker works inside the iframe, but lists only the signed-in user's own and published knowledge bases. Every switch is reauthorized through DeerFlow and receives a fresh short-lived iframe session, so it never exposes the upstream service-admin knowledge-base list.
 - **Prefixed WeKnora deployment**: the frontend may be published under a separate prefix such as `/magentweb`, while embedded WeKnora detail traffic is served by the Gateway under `/deerflow`. The Gateway rewrites HTML root assets, WeKnora API URLs, redirects, and Vite dynamic dependency maps so page assets stay under `/deerflow`; the prefixed proxy routes must be registered before the unprefixed fallback. The signed embed cookie covers `/deerflow`, and auth/CSRF recognition includes all supported static directories.

+Whole-report rewrite builds its requirement plan locally from the selected

+regeneration boundary: it copies the completed report and selected evidence
+into a new session (including both saved `[来源：id]` and legacy streamed
+`[[source:id]]` citation markers remapped to the cloned ids). The following
+durable writer is explicitly queued with `operation=generate`: it does not send
+the inherited report to the model as text to edit, and instead writes a fresh
+report from the complete selected evidence set plus the newly confirmed
+outline. Model reasoning remains a live SSE event before the first Markdown
+token. New output uses display-ready `[来源：id]` citations; validation repairs
+only unique near-complete `drs_src_*` ids (for example a provider-truncated
+suffix) and still rejects genuinely unknown evidence ids.
+The report-only model stream requests an 8192-token completion budget so a
+normal multi-section report and its reference list do not stop at the common
+4096-token provider default; malformed trailing citation syntax is rejected
+rather than committed as a partial document.
+The original report therefore remains independently available in history even

+Whole-document rewrite commits the artifact/report before it attempts to store

+# 外部系统智能体会话与消息 API
+
+Base URL 为 Gateway 的 `/api`（部署若由反向代理配置了前缀，以网关实际暴露地址为准）。所有接口沿用现有 `Authorization: Bearer <token>` 鉴权；无效或过期 token 返回 `401`。
+
+## 会话隔离键
+
+外部系统创建和检索会话时使用以下**精确拼写**的 metadata 键，三个值均为字符串：
+
+| 键 | 类型 | 约定 |
+| --- | --- | --- |
+| `agent_id` | string | 智能体 ID |
+| `task_id` | string | 任务 ID；数字也必须传字符串 |
+| `chat_type` | string | 页面决定的隔离标识；UTF-8 原样保存、原样比较、原样返回，不做 trim、大小写转换或枚举校验 |
+
+`chat_type` 的可用长度大于 64 字符（metadata 存为 JSON 对象）。存量未带 `chat_type` 的线程保持原有行为；只有检索条件中显式提供 `chat_type` 时才会要求该字段精确相等。
+
+## 1. 创建与按隔离键查找会话
+
+### `POST /api/threads`
+
+| 参数 | 位置 | 必填 | 类型 | 说明 |
+| --- | --- | --- | --- | --- |
+| `metadata.agent_id` | body | 是（外部集成约定） | string | 智能体 ID |
+| `metadata.task_id` | body | 是（外部集成约定） | string | 任务 ID |
+| `metadata.chat_type` | body | 是（新会话） | string | 页面隔离键 |
+| `thread_id` | body | 否 | string | 不传则服务端生成 UUID |
+| `assistant_id` | body | 否 | string | 现有兼容字段 |
+
+```json
+{
+  "metadata": {
+    "agent_id": "c353429a73e146ae9e6926054b2d155a",
+    "task_id": "108",
+    "chat_type": "测试分析"
+  }

+
+匹配结果按 `updated_at` **倒序**，并以 `thread_id` 倒序作同时间稳定排序。响应返回完整 metadata。
+
+## 2. 读取会话消息
+
+### `GET /api/threads/{thread_id}/messages`
+
+| 参数 | 位置 | 必填 | 类型 | 默认／范围 | 说明 |
+| --- | --- | --- | --- | --- | --- |
+| `thread_id` | path | 是 | string | - | 会话 ID |
+| `limit` | query | 否 | integer | `200`，`1..1000` | 返回消息数 |
+| `offset` | query | 否 | integer | `0`，`>=0` | 从最早消息起跳过的消息数 |
+
+消息按照会话内实际写入顺序（时间正序）返回，`total` 为分页前总条数。接口读取最新 LangGraph checkpoint，并使用与 `state`／流式消息相同的序列化路径：不按展示用途裁剪 `additional_kwargs`、`tool_calls`、隐藏消息或供应商扩展字段。
+
+```json
+{
+  "total": 2,
+  "messages": [
+    {
+      "type": "human",
+      "id": "msg-1",
+      "content": [{"type": "text", "text": "隐藏上下文"}],
+      "additional_kwargs": {"hide_from_ui": true, "client_ts": "2026-08-22T18:00:00+08:00"}
+    },
+    {
+      "type": "ai",
+      "id": "msg-2",
+      "content": "这是回答",
+      "tool_calls": [{"name": "lookup", "args": {"keyword": "测试"}, "id": "call-1"}],
+      "additional_kwargs": {"reasoning_content": "完整思考字段", "hide_from_ui": false}
+    }
+  ]
+}
+```
+
+`hide_from_ui` 位于消息的 `additional_kwargs.hide_from_ui`（若该消息实际带有此字段）。`tool_calls[].args` 不被转换：LangChain 已解析的标准 `tool_calls` 通常是 JSON 对象；供应商原始工具调用若保留在 `additional_kwargs`，其原始字符串／对象形态也保持不变。
+
+## 3. 删除一轮对话
+
+### `DELETE /api/threads/{thread_id}/messages/{message_id}`
+
+`message_id` 应取自消息列表中用户消息（`type: "human"`）的 `id`。删除该问题及其后的 AI、工具、中间消息，直到下一条用户消息之前；若传入的是非用户消息 ID，仅删除该消息。删除会写入新的 checkpoint，随后读取消息列表即可获得已删除后的结果。
+
+成功示例：
+
+```json
+{
+  "ok": true,
+  "deleted_ids": ["question-1", "answer-1", "tool-1"],
+  "remaining": 2
+}
+```
+
+## 4. 删除整个会话
+
+### `DELETE /api/threads/{thread_id}`
+
+清理该线程的 checkpoint（含消息）、线程 metadata 与该线程目录下的上传文件／工作区／生成产物。会话检索不再返回该线程。
+
+```json
+{"success": true, "message": "Deleted local thread data for c7cefe92-84f8-4f31-aed0-a16f7b151cc2"}
+```
+
+## HTTP 错误
+
+| 状态码 | 触发条件 | 响应体示例 |
+| --- | --- | --- |
+| 401 | 缺少、无效或过期的 Bearer token | `{"detail":"Authentication required"}` |
+| 403 | token 没有对应线程权限 | `{"detail":"Permission denied: threads:read"}` |
+| 404 | 线程不存在、无权访问、或 `message_id` 不存在 | `{"detail":"Thread xxx not found"}` |
+| 409 | 上述接口当前不使用 409 | 不适用 |
+| 422 | 分页参数越界，或请求体字段类型不合法 | FastAPI 标准校验错误对象 |
+| 429 | 上述接口本身未配置限流；如部署侧网关限流，由部署网关返回其配置的响应体 | 不适用 |
+| 500 | checkpoint 或持久化读取／写入失败 | `{"detail":"Failed to get thread messages"}` 等 |
+
+时间字段 `created_at` 与 `updated_at` 使用 ISO 8601、带 UTC 偏移量；不是毫秒时间戳。
+
+## 兼容性与生命周期
+
+- 既有 `/threads`、`/runs/stream`、`/models` 调用不改动；仅新增消息查询，并修复单轮删除的 checkpoint 持久化。
+- 普通线程未配置通用自动过期策略、单任务会话数上限或 `chat_type` 枚举；保留至调用方删除或运维侧另行清理。AI 写作等独立业务的专用清理策略不适用于本接口。
+- 外部系统的联调 task、预置线程、发布窗口和联系人属于部署运维信息，不在代码中硬编码；请在目标测试环境创建后补入联调单。
+- Swagger 地址为 `<Gateway Base URL>/docs`；OpenAPI JSON 为 `<Gateway Base URL>/openapi.json`。
