 - **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`

 | **Knowledge** (`/api/knowledge`) | Product knowledge base, **global/shared** (no user isolation; writes record `created_by`/`updated_by` for audit). `POST /ingest/thread/{thread_id}` - sediment one thread into a note (reads messages from the checkpointer, `threads:read` owner-checked); `POST /ingest/threads/batch` - batch-sediment the caller's recent threads (`skip_existing` via `.manifest.json` dedup). **Defaults to `background=true`**: the slow per-thread extraction loop is deferred to a FastAPI background task and the endpoint returns `{queued:true, processed:N}` immediately (each thread's transcript is truncated to `max_input_chars` before the LLM call). Running the loop inline for a large batch outlives the nginx gateway timeout (504), which the frontend's `parseResponse` surfaces as a generic "Request failed"; `background=false` keeps the blocking path (full per-thread `created/skipped/failed` tally) for small batches/scripts. Shared loop: `_run_batch_ingest`. **Optional model selection**: both ingest endpoints accept `model_name` (overrides `knowledge.extract_model_name` for that capture; threaded through `KnowledgeService.capture_thread` ? `extract_thread_llm_multi`). **Model-error surfacing**: when the chosen model produces nothing usable (timeout / API error / non-JSON) capture still **falls back to rule-based extraction and lands a draft** (`llm_fallback:true`); the single-thread (non-background) response and the batch response (`llm_fallback` count) carry this so the UI tells the user "???????". The "??????" chat button stays background/fire-and-forget (passes `model_name`, no per-save error toast); the batch-import dialog is synchronous and shows the fallback count. `POST /ingest/file` - **import an uploaded file** (multipart: `file` + optional `title`/`tags`/`status`/`model_name`) into wiki note(s): the file is converted to Markdown (md/txt read directly, pdf/word/ppt/excel via `convert_file_to_markdown`), distilled by the same wiki-capture LLM pipeline as thread capture (`source_type="file"`), and falls back to a verbatim **draft** note when the model returns nothing usable (`llm_fallback:true`); `POST /ingest/search` - sediment search/tool results as a reference note; `POST /notes` - manual note; `GET /notes` (keyword/tag/source_type/status + pagination); `GET/PUT/DELETE /notes/{id}` (DELETE is soft = archive, `?hard=true` removes the vault file); `POST /search` - `mode=keyword\|vector\|hybrid` (vector?keyword fallback when no embedding endpoint); `GET /notes/{id}/versions` - edit history; `GET /duplicates` + `POST /merge` - dedup; `POST /reindex` - rebuild vector index; `GET /graph` - product graph data (notes + entities, graph-blacklist filtered); `GET/POST /graph/blacklist` + `DELETE /graph/blacklist/{id}` - graph node blacklist (labels = entity names / note titles, case-insensitive match; blacklisted nodes and their edges are dropped from `/graph` and the wiki-export artifacts; table `knowledge_graph_blacklist`, auto-created); `POST /export/graph` + `GET /export/files/{graph.json\|graph.html\|graph.graphml\|cypher.txt}` - obsidian-wiki `wiki-export` artifacts (self-contained `graph.html` for iframe); `POST /resolve` `{targets:[?]}` + `GET /notes/{id}/wikilinks` - resolve `[[wikilink]]` targets to a note id / vault page / missing (powers clickable wikilinks); `GET /vault-page?path=` - read a raw vault meta/hub Markdown page (no DB note). `GET/POST /folders` + `PUT/DELETE /folders/{id}` - user-managed directories (notes carry a `folder` path; `GET /notes?folder=` filters a dir + sub-dirs); `GET/POST /extract-templates` + `GET/PUT/DELETE /extract-templates/{id}` - editable extraction-prompt templates (thread/document ingest accept `template_id`; capture/PUT-note accept `folder`).

+
+## 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.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 |

+| `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`。

+"""Cap deliverable tools for position-roundtable seats.
+
+Weak models (especially after a first successful Markdown write) often call
+``write_file`` again with another copy of the same report, or call
+``present_files`` twice for the same path, and loop until the recursion
+limit kills the run. The UI then shows two identical "Successfully
+presented files" cards even though only one file exists on disk.
+
+When the run context carries ``position_artifact_cap`` (set by the position-
+roundtable UI for ordinary seats and the summary agent — **not** for
+action-plan, which must emit report + JSON), this middleware:
+
+1. Truncates excess outputs ``write_file`` **and** ``present_files`` calls in
+   a single model response (keeps only the first *N* of each), including
+   raw provider metadata.
+2. Rejects further such calls once *N* successful *or* earlier in-batch
+   calls already exist in the current user turn (so parallel tool calls
+   cannot race past the cap).
+3. Ends the turn when the only remaining calls were excess writes/presents.
+4. Injects a brief hidden reminder before the next model call:
+   - write done, not yet presented → present once, then wrap up;
+   - write **and** present already done → wrap up, do **not** present again.
