@@ -98,6 +98,7 @@ The frontend (`frontend-web/`) is a React 19 + Vite SPA:
 - **技能上下线 (Skill Availability, owner/admin)**: the global `Skill.enabled` flag is the online/offline switch. Taking a skill offline persists `skills.<name>.enabled=false` in `extensions_config.json` but does **not** delete its directory or remove it from existing agent/workflow configurations; the row remains visible and bringing it online restores those references. Administrators may toggle every skill from 「技能管理」; ordinary users may toggle only their own non-built-in `custom` skills from 「技能 → 技能列表 → 我的」. Offline skills must be absent from every model-facing skill catalogue (`lead` prompt, `search_skills`, `skill_list`, `skill_view`, subagents, AI writing/deep research/roundtable and Workflow run-start validation), from agent skill pickers, and from direct sandbox access: `read_file`/`ls`/`glob`/`grep`/`bash` reject offline, unknown, root-wide and category-wide `/mnt/skills` paths. The backend mutation is `PUT /api/skills/{name}`, authorizes either an administrator or the persisted owner of the target custom skill, patches the raw document so MCP placeholders and unrelated extension fields survive, uses atomic replacement when supported plus a Docker single-file-bind fallback, and refreshes the skill prompt cache. Launchers keep the runtime extensions file in a writable persisted directory. Existing agent/strategy-agent references stay visible as 「已下线」 and may be removed but not newly selected.
 - **技能地址管理 (Skill Address Management, admin-only)**: 扫描运行中的技能（`skills/{public,custom}` 下所有 `.md`/`.py`）里的 **http(s) URL 与 IP/IP:端口**，按唯一地址聚合全部出现位置（跨 .md/.py），支持**批量替换**（如把 UAT 地址一次性改成生产）。主体抽成可复用组件 `SkillAddressesPanel`（`pages/SkillAddressesPage.tsx` 导出，默认导出 `SkillAddressesPage` 仍保留旧路由 `/page/strategy/admin/skill-addresses` 作直链回退），**作为「技能地址管理」标签页嵌入管理员「技能管理」页 `pages/AdminSkillsPage.tsx`**（该页加 Tabs：「技能列表」+「技能地址管理」；入口在「设置和更多」下拉的「技能管理」`workspace-nav-menu.tsx` → `/page/workspace/admin/skills`，不再单列于 `components/page-sidebar.tsx` 左下角设置下拉）：打开自动扫描并带**进度条**（扫描逐技能 / 应用逐文件 X/N，应对 150+ 技能），URL/IP 类型过滤 + 搜索 + 「片段批量套用」（如所有 `uat.4.cn` → `prod.4.cn`）、每地址「替换为」输入框（可展开看 `file:line` 片段）、内联**预览**、**应用**、**多关键词检索**（空格分隔全部命中），以及**修改记录**面板——每次应用生成一条记录（显示时间/改了哪些地址 from→to/文件数/处数），可**针对单次记录回退**（二次确认）。client + NDJSON 流式解析在 `strategy-components/api/skill-addresses.ts`。后端 `/api/skill-addresses`（**仅管理员**）：所有文件 IO 走 `asyncio.to_thread` 不阻塞事件循环；`GET /scan`(+`/scan/stream`)、`POST /preview`、`POST /apply`(+`/apply/stream`)、`GET /backups`、`POST /rollback/{id}`；**子串安全替换**（基于 token span，不会误伤子串）、`expected_total` 乐观锁（409）、写前自动磁盘备份到 `{skills_root}/.address-edits/`（同时写一份 `{id}.manifest.json` 记录本次替换明细，供修改记录展示）、应用后刷新技能系统提示缓存。纯引擎 `deerflow/skills/address_scan.py`，router `app/gateway/routers/skill_addresses.py`，tests `tests/test_skill_addresses.py`。范围仅运行中技能，不动 `deploy/minimal/skills/`。
 - **按钮管理 (Task Button Management, admin-only)**: configures the **可配置跳转按钮** rendered in the left task panel of the task deep-link workspaces (rwfx / 3qfx / xdfx, see `TaskFxWorkspace`). Each button = `{business, label, linkType, target, appendTaskId, idParam, idKind, enabled, sortOrder}`; `linkType` is `url` (外链 `window.open`, optional append of `?{idParam}={id}` — **`idParam` is the editable query-param name**, e.g. `id`/`task_id`), `business` (内部切换到另一业务, reuses `resolveTaskDeeplinkTarget`, always task id), or `purpose` (弹出当前任务的「任务目的」表格 via the shared `TaskPurposeDialog`, no target — configurable for any page incl. xdfx). **`host`（宿主路由）** asks the embedding parent to navigate: `runTaskButton` sends `window.parent.postMessage({ type:'HOST_NAVIGATE', path, queryParams:{ [idParam]: Number(taskId) } }, hostOrigin)` — `target` is the host route, `appendTaskId`/`idParam` become numeric `queryParams` (task id, or action id when `idKind:"action"` — same selector as url buttons, xdfx only), origin from `runtime-config.js` `VITE_HOST_NAVIGATE_ORIGIN` (else ancestorOrigins/referrer; never `*`). **`idKind` (`task`/`action`) only matters for xdfx**: its deep-link `?taskId=` is an 行动id and the 任务id is resolved at login (`fetchTaskIdFromAction`) — `TaskContext` now also stashes the raw `actionId`, so a url **or host** button can append either (default `task`). 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/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. The old hardcoded jump buttons were migrated out: `TaskFxWorkspace` no longer hardcodes 切换到三情分析, `TaskActionsPanel` keeps only the non-jump 清除记录, and `TaskPurposePanel` dropped its 3q详情 button (now configurable) **and defaults the 目的树 table to collapsed** (chevron toggle). Helpers `core/auth/task-buttons.ts` (`TaskButton`, `defaultTaskButtons`, `resolveTaskButtons`, `buttonsForBusiness`, `runTaskButton`), client+hooks `strategy-components/api/task-buttons.ts`. Backend: `/api/task-buttons` (global/shared; open read, admin replace-all), store `deerflow.persistence.task_buttons` (table `task_buttons`, auto-created by `create_all`), wired `app.state.task_button_store`. Tests: `tests/test_task_buttons.py`.
+- **单智能体任务深链聊天记录（2026-10-19）**: `3qfx` / `rwfx` / `xdfx` 的会话历史使用独立 `task_deeplink_threads` 索引表及 `GET /api/task-deeplink-threads?task_id=&go_path=`，前端由 `useTaskDeeplinkThreads` 读取，不再筛选通用聊天列表。LangGraph thread/checkpoint 仍是消息权威数据；专用表仅按 `(task_id, go_path)` 定位 thread。`3qfx/rwfx` 按任务 id，`xdfx` 按 URL 原始行动 id；新 thread 写 `metadata.{taskRecordId,taskGoPath,thread_type:"task_deeplink"}` 并自动登记，通用最近对话默认隐藏。迁移 `20261019_01` 只建表、**不迁移/回填旧数据**。
 - **上下文近 3 轮滑窗（管理员全局开关）**: 「设置 → 上下文管理」可开启 `system_settings.json -> conversation_context.recent_turn_window_enabled`（默认关闭；`GET/PUT /api/system-settings/conversation-context`，PUT 仅管理员）。开启后 `RecentTurnsMiddleware` 只改变单次模型请求，保留含当前轮在内的最近 3 个真实用户回合及其 assistant/tool 链；checkpoint 与前端完整聊天记录不删。该模式优先于聊天框「上下文压缩」，且不会调用摘要模型；关闭后沿用原压缩行为。实现 `deerflow/agents/middlewares/recent_turns_middleware.py`，回归 `tests/test_summarization_multiturn.py` / `tests/test_prompt_prefix.py`。

CLAUDE.md

@@ -133,6 +133,7 @@ The frontend (`frontend-web/`) is a React 19 + Vite SPA:
 - **会话冲突与模型工具流恢复**: 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` returns the Chinese detail「当前对话还在生成回答…」). `core/threads/hooks.ts` detects the conflict and routes it through `confirmOrRejoin`. Run-creation SSE responses expose `Content-Location` plus the SDK `Location` reconnect endpoint; `core/api/api-client.ts` records the last consumed event id, so an in-page rejoin resumes after that cursor instead of replaying tool arguments from `-1`. `write_file` argument updates carried by `messages-tuple` count as business activity. A known active run is probed only after 90 seconds without a business frame; the watchdog hides `lg:stream`, stops only the old browser reader, and rejoins without cancelling the backend run. Clean EOF, transport errors, 409 and watchdog recovery share one single-flight Promise to prevent duplicate joins/finalization. The backend `PatchedChatOpenAI` separately normalizes confirmed cumulative argument snapshots and bounded compatible response shapes while preserving standard deltas; its content-free diagnostics never log prompts, arguments or file bodies.
 - **React #185 与流式刷新保护**: every direct LangGraph `useStream` surface (main/agent chat, AI writing, Canvas and Studio notebook) uses shared `STREAM_RENDER_BATCHING = true`. The installed SDK implements numeric `throttle: 16` as a trailing debounce, which can indefinitely postpone UI updates during a continuous fast stream; `true` retains asynchronous next-task batching without requiring 16ms silence. `stream-error-classification.ts` detects `Maximum update depth exceeded` / production `#185` through bounded, cycle-safe wrappers. Main chat filters the SDK's stored error and duplicate submit rejection; `react-ui-error.ts` gives each send at most one automatic UI recovery, then pauses rejoin without cancelling the server run. Token activity must not reset that budget. The top-level `ReactUiErrorBoundary` catches only this render/commit error, shows a static friendly reload panel, and never automatically remounts the failing tree. Other errors are not swallowed. Shared toasts are deduplicated for 30 seconds; diagnostics retain error type, recovery phase, thread/run identifiers and component stack but never message/tool content. Real SDK SSE replay covers partial reasoning and write_file Markdown before generation ends; the browser boundary check triggers a real production React layout-effect loop and requires manual reload to recover. These safeguards do not prove the unknown production component loop is fixed.
 - **流式游标作用域**: resumable cursors belong to the current SDK message accumulator, not a module-global map. `createStreamAPIClient` isolates same-reader recovery; newly mounted chats and real thread switches must replay the retained prefix instead of borrowing another reader's consumed position. Clearing replaces the cursor map so late old-reader events cannot pollute the new scope. The shared `getAPIClient` does not rewrite replay-from-start cursors. `stream-cursor-replay.test.ts` uses the real SDK to protect against both duplicate tool arguments on reconnect and missing prefixes on reopening.
+- **单智能体任务深链聊天记录（2026-10-19）**: `3qfx` / `rwfx` / `xdfx` 已不再通过 `useTaskThreads` 扫描、过滤通用 `threads_meta` 列表；`TaskFxWorkspace` / `TaskFxIndexResolver` 统一调用 `useTaskDeeplinkThreads` → `GET /api/task-deeplink-threads?task_id=&go_path=`，读取独立表 `task_deeplink_threads` 的 `(task_id, go_path)` 索引，再按 `thread_id` 关联 canonical `threads_meta` 标题/状态（消息与 checkpoint 仍由 LangGraph 管理）。新会话 metadata 写 `taskRecordId`、`taskGoPath`、`thread_type=task_deeplink` 并由 thread-meta 仓储同事务登记；`3qfx/rwfx` 的 `taskRecordId` 是任务 id，`xdfx` 是 URL 原始行动 id（真实任务 id 仍保留在 `metadata.taskId` 维持共享访问语义）。普通聊天记录默认隐藏该 thread type；显式 taskId 查询仍可读取。迁移 `20261019_01` **只建表、不回填旧数据**，因此上线前旧深链会话不会出现在新列表。`/api/open/3qfx/ask` 同样写专用索引。Tests: `packages/harness/tests/test_task_deeplink_threads.py`, `src/core/auth/task-purpose-metadata.test.ts`, `src/core/threads/hidden-chats.test.ts`。
 - **State**: TanStack Query for server state, context providers (`SubtasksProvider`, `ArtifactsProvider`, `PromptInputProvider`) scoped to `WorkspaceRoutes`
 - **LLM streaming**: `@langchain/langgraph-sdk` streams messages from the backend via SSE
 - **UI**: Radix UI primitives + TailwindCSS v4 + shadcn-style components in `src/components/ui/`

Startup seeds the real database row with 20 files, 100 MiB total, documents/images 10 MiB each, spreadsheets 5 MiB, and large-file budgets 12k/32k chars. The validated row is also published to the harness runtime registry without introducing an `app.*` import. |
 | **Uploads** (`/api/threads/{id}/uploads`) | `POST /` reads the latest database policy, enforces category extensions/sizes/total/count, validates signatures/OOXML containers/text encoding, then commits the whole staged batch or rolls it back; optional document conversion uses `<original-name>.<ext>.md`. `GET /limits` returns the full effective policy plus compatibility fields; `GET /list` lists; `DELETE /{filename}` deletes. Uploaded raster images also receive a signed public HTML URL (`/api/public/html-images/{token}`) so generated pages can use them as `background-image`. |

Thread metadata carrying `taskRecordId + taskGoPath` is dual-written atomically by both SQL and memory thread stores and deleted with the thread. `3qfx/rwfx` use the task id as `taskRecordId`; `xdfx` uses the original action id while retaining the resolved real task id in `metadata.taskId`. `thread_type=task_deeplink` keeps these rows out of general recent chats; explicit `taskId` searches still opt out of that exclusion for compatibility. Alembic `20261019_01` is schema-only and intentionally does **not** backfill legacy task threads. Frontend hook: `core/threads/use-task-deeplink-threads.ts`. Tests: `packages/harness/tests/test_task_deeplink_threads.py`, `packages/harness/tests/test_thread_meta_task_lookup.py`. |
 | **Threads** (`/api/threads/{id}`) | `DELETE /` - remove DeerFlow-managed local thread data after LangGraph thread deletion; unexpected failures are logged server-side and return a generic 500 detail |
 | **Threads search** (`POST /threads/search`, LangGraph-compat) | Conversation listing. **System threads are excluded by default**: rows whose `metadata.system` is truthy (scheduler runs, roundtable workers) or whose `thread_type` is a known system type (`task-analysis` seat runs included; older seat rows are also matched by `task_analysis_seat`) never crowd the user's list; a caller whose `metadata` filter explicitly references `thread_type`/`system` (e.g. studio notebooks) opts out of the exclusion. New `query` field = case-insensitive title (`display_name`) substring search, used by the chats page's server-side pagination. `POST /threads/count` takes the same request body (limit/offset ignored) and returns `{total}` under identical filtering/exclusion semantics ? powers the chats page's ??/??? display without fetching rows (`ThreadMetaStore.count`). `ThreadMetaStore.search` gained `exclude_system`/`query` params; JSON-blob filters batch-scan until the requested `limit`/`offset` window is full (so pagination over a heavily-filtered set never under-fills), with a `thread_id` tie-breaker on the `updated_at DESC` ordering for stable OFFSET paging. Tests: `tests/test_thread_meta_search.py` |
 | **Artifacts** (`/api/threads/{id}/artifacts`, `/api/artifact-library`, `/api/strategy-project-artifacts/{id}/download`) | `GET /{path}` streams thread artifacts; active content types (`text/html`, `application/xhtml+xml`, `image/svg+xml`) are always forced as download attachments to reduce XSS risk; `?download=true` still forces download for other file types. `GET /api/threads/{id}/artifact-preview?path=` returns bounded text, using streaming statistics plus deterministic head/middle/tail samples above the database threshold. `GET /api/artifact-library` combines every current-user normal thread's authoritative `outputs/` files with completed strategy-selection syntheses projected from the owner-scoped `parallel_agent_tasks.messages` snapshot. Strategy items use `source_type=strategy`, carry `strategy_project_id` / `strategy_name` / `strategy_stale`, and explicitly distinguish `strategy_source_kind=strategy_selection` from an `analysis_project_mode=strategy` thread (`analysis_project`); virtual items also expose `download_url`, so clients never infer routing from sentinel thread/path values. Search/source filters cover both. `workflowStale=true` keeps the last completed historical synthesis visible and downloadable. The dedicated strategy download route revalidates current-user ownership and snapshot completion and serves Markdown without pretending the virtual item is a thread artifact. Uploads and image/audio/video media remain excluded. Library metadata is persisted in `artifact_library_items`; list/search/filter/count/pagination read only this user-scoped SQL index. A generation-fenced `artifact_library_sync_states` lease schedules low-concurrency filesystem/task reconciliation in the background on first/stale reads or `refresh=true`, keeps the last successful snapshot visible during refresh/failure, and reports `sync_status` / `syncing` / `indexed_at` / `sync_error` to the client. Files themselves remain authoritative on disk and are never copied into the database. |

+### openGauss Dolphin / MySQL-protocol mode
+
+The offline deployment may select `DATABASE_TYPE=gauss_mysql`.  Its renderer
+keeps `database.backend=mysql` and sets `DEERFLOW_DATABASE_PRODUCT=gauss_mysql`;
+this explicit product marker is the switch because SQLAlchemy cannot safely
+distinguish Dolphin from MySQL before dialect initialization.  Only that mode
+installs `deerflow.persistence.gauss_mysql_compat` for the configured async
+driver.  An unset marker, or `mysql`, must retain the stock MySQL dialect and
+schema-maintenance behavior unchanged.
+
+Dolphin table existence and additive schema checks use `current_schema()` plus
+the native `pg_catalog` through `gauss_schema.ensure_gauss_schema_sync`.
+Never run the generic MySQL `SHOW CREATE TABLE` reflection sweep, MySQL JSON
+projection backfill, MySQL session-timeout variables, or application-side
+`CREATE DATABASE` retry in this mode: these paths can misread the schema or
+abort the openGauss transaction with error 322.  Database/user/schema bootstrap
+remains the offline deployment layer's responsibility.  The startup DDL block
+is still best-effort under the global startup-schema invariant and always
+releases its host-local cross-worker lock.
+
+`PortableJSON` writes strict JSON for both products.  Its legacy decoder is
+available only on a dialect class carrying the Dolphin compatibility marker;
+ordinary MySQL must continue to reject malformed/non-JSON values rather than
+silently applying the Dolphin fallbacks.

-你是「商业态势」页面的右侧对话助理，负责一个任务详情文档（8 个区块的 JSON）。
-用户可能提问、总结，也可能要求修改某部分内容。
-
-## 顶层区块 key（固定 8 个，一个不能多、不能自造）
-
-`situationBriefs`（情报摘要）/ `currentJudgments`（当前判断）/ `importantTargets`（重要目标）/
-`importantTimeNodes`（重要时间节点·时间轴）/ `insightTopics`（话题热度）/
-`insightRisks`（风险）/ `insightOpportunities`（机会）/ `taskConnections`（任务衔接）。
-
-除 `taskConnections` 外，每条业务数据带 `latitude`/`longitude`（与态势页敌情目标同字段）。
-修改数组时必须原样保留这两列，不要删、不要改成 lat/lng。还必须保留接口追溯字段：
-时间节点的 `recUuid`，三类事件的 `id/eventId`，目标的 `eid`，衔接任务的 `taskId`
-和 `sourceConnectionType`，以及所有来源/发布时间字段。
-
-## 页面说法 → key 对照（用户指着页面哪里就按这张表找 key）
-
-| 页面位置 / 用户说法 | key |
-| --- | --- |
-| 情报摘要（左栏：敌情摘要/我情摘要/环境摘要） | `situationBriefs` |
-| 重要目标（左栏，G01/G02/G03 目标卡） | `importantTargets` |
-| 当前判断（中栏任务统筹面板上方，研判卡+置信度） | `currentJudgments` |
-| 任务衔接（中栏任务统筹面板，打击/塑势泳道） | `taskConnections` |
-| 重要时间节点（中栏任务统筹面板下方的时间列表） | `importantTimeNodes` |
-| **态势研判（左栏面板，三个 tab：态势/风险/战机）** | 态势 tab=`insightTopics`、风险 tab=`insightRisks`、战机 tab=`insightOpportunities`（更新哪看 tab） |
-| 左上角任务详情（任务名/方向/类型/时间） | 通过 `fs-task-detail-info` 实时读取；不写入八区块详情 |
-| 底部态势时间轴（刻度） | **不是数据区块**——它是版本历史刻度，没有可更新内容 |
-
-fs-detail-update 已内置中文别名（重要目标/当前判断/态势研判/重要时间节点/时间轴等
-会自动映射到对应 key），但提交时仍应优先使用上面的英文 key。
-
-## 开场上下文
-
-每个新会话的第一条用户消息会带【开场上下文】：详情任务 task_id + 当前详情完整
-JSON。以它为基线；多轮对话后数据可能已变，**修改前先重新读取**。
-
-## 场景一：问答 / 总结 / 指代不明
-
-用户对页面内容提问、总结或指出错误但没说清具体条目（如"判断里第一条不对"）——
-先读取再回答（bash）：
-
-```bash
-python /mnt/skills/custom/fs-detail-read/scripts/fs_detail_read.py --task-id <task_id>
-```
-
-读到最新内容后对照作答；读不到时如实说明，**不要编造当前数据**。纯问答回合
-**不要**输出任何修改回执。
-
-如果用户询问任务名、方向、任务类型、创建/更新时间，再执行：
-
-```bash
-python /mnt/skills/custom/fs-task-detail-info/scripts/fs_task_detail_info.py --task-id <task_id>
-```
-
-## 场景二：修改部分内容（核心流程，带用户确认）
-
-1. **读取基线**：先调 fs-detail-read 拿最新详情；
-2. **定位**：把用户的口语指代对应到具体区块/条目（如"判断中的第一个数据"=
-   currentJudgments[0]），拿不准就先复述确认；
-3. **生成补丁**：只包含**被修改的顶层 key**。数组区块**必须完整**——以读取结果
-   为底，只替换目标条目，其余条目逐字原样保留。用 write_file 把补丁写到
-   `/mnt/user-data/outputs/patch.json`（虚拟路径；JSON 直接写汉字，禁止 \\uXXXX 转义）。
-   这一步只调用 write_file，不要在同一条消息里写给用户看的总结。
-4. **下一条回复只写总结，禁止调用任何工具**：write_file 返回后，单独再输出一条
-   用户可见正文。这条消息里不能有工具调用，也不能把总结只写进思考过程。
-   正文用 markdown 表格列出将要更新的数据，每条一行：
-
-   | 区块 | 更新后内容 |
-   | --- | --- |
-   | 敌情摘要 | 竞对A品牌销量逆势增长15%，主攻低端市场… |
-   | 我情摘要 | 我方主力产品销量稳步增长，华东区域市… |
-
-   （区块用页面中文名，内容为写入数据的原文，不要只写"无变化"占位）
-   **不要调用 ask_clarification。** 你输出完表格后，系统会自动在这条正文后面弹出
-   确认卡（更新 / 增加）。你停在表格即可，等用户在卡片上选择。
-5. **按用户选择调整补丁并提交**（fs-detail-update 合并提交，不会清掉未提交区块）：
-   - 选「更新」→ 补丁原样提交；
-   - 选「增加」→ 读取结果里**已经有该区块的非空数组**时，以读取结果为底，把新条目
-     append 到数组尾部，旧条目全部保留后提交；该 key **不存在、为 null 或为空数组**
-     时，没有旧条目可拼，补丁数组原样作为新区块提交；
-   - 自定义输入 → 按用户要求调整补丁后提交；用户写了「取消」→ 不提交，回复已取消；
-
-```bash
-python /mnt/skills/custom/fs-detail-update/scripts/fs_detail_update.py   --task-id <task_id> --data '@/mnt/user-data/outputs/patch.json'
-```
-
-6. **汇报 + 回执**：提交成功（stdout `"success": true`）后，必须先用 **markdown 表格**
-   逐条展示本次更新的数据（区块中文名 + 更新后的完整内容，每条一行；新增/修改的
-   条目都要列，不要只写"新增了 N 条"的摘要），表格格式：
-
-   | 区块 | 更新后内容 |
-   | --- | --- |
-   | 敌情摘要 | 竞对A品牌销量逆势增长15%，主攻低端… |
-   | 我情摘要 | 我方主力产品销量稳步增长，华东区域市… |
-
-   （多区块/多条目就多行；表格里只写数据本身，不要写"无变化"之类的占位行）
-   然后在回复的**最后一行**原样输出修改回执（前端靠它刷新页面数据，纯问答不输出）：
-
-```
-FS_DETAIL_UPDATED:{"task_id":"<task_id>","keys":["<被修改的区块key>"]}
-```
-
-   回执必须独占最后一行、JSON 紧凑单行、task_id 与 keys 用真实值；失败时把
-   errors 原样反馈并重试一次（重试也不输出回执，直到成功）。
-
-## 场景三：重新收集某区块（同样带确认）
-
-用户说"重新获取/刷新某块"时：
-
-1. 接口来源区块使用只采集不写入模式，拿新一版数据后**不要自己改写**：
-   `python /mnt/skills/custom/fs-collect/scripts/fs_collect.py --group source --keys <区块key> --task-id <task_id> --dry-run`。
-   `importantTargets` 会先重新查三类事件 id，再调用 entites；`situationBriefs` 用
-   `--group summary --dry-run`；`currentJudgments` 使用
-   `--group judgment --keys currentJudgments --dry-run`，由独立接口技能固定传 `discriminant=威胁`；
-2. 把采集输出整理成补丁 write_file 到 `/mnt/user-data/outputs/patch.json`（这一步只写文件）；
-3. write_file 返回后，下一条回复只输出 markdown 表格（区块 | 更新后内容，每条一行），
-   不调用任何工具。系统会在表格后自动弹出确认卡；
-4. 用户确认后按场景二第 5-6 步调整补丁、提交、回执。
-   （无人值守场景不存在——你只服务交互对话，凡写入必须先确认。）
-
-**重要：接口采集默认使用独立任务详情中的 direction 和 taskName 作为关键词。**用户明确
-指定关键词时可传 `--keyword` 覆盖；当前判断必须调用 fs-current-judgment-info，禁止
-回退到固定模板或自行改写接口结果。然后照常走「write_file → 表格确认 → 提交」流程。
-
-## 场景四：详情缺了某一块，要补上去
-
-用户说「这块没有 / 缺了 / 空的 / 补上 / 补充」时，先 `fs-detail-read`。某个顶层 key
-**不在文档里、值为 null，或是空数组**，都算缺失。缺失不是拒绝理由，禁止回复
-「详情里没有这块，无法修改」。
-
-1. 按缺失的 key 采集整块，只采集不写入（和场景三同一条命令，不要自己编条目）：
-   - `importantTargets` / `importantTimeNodes` / `insightTopics` / `insightRisks` /
-     `insightOpportunities` / `taskConnections`：
-     `python /mnt/skills/custom/fs-collect/scripts/fs_collect.py --group source --keys <区块key> --task-id <task_id> --dry-run`
-   - `currentJudgments`：
-     `--group judgment --keys currentJudgments --dry-run`
-   - `situationBriefs`：来源区块也缺时先按上面把来源补进详情，再
-     `--group summary --dry-run`
-2. 采集结果里该 key 的数组**整段**写入 `/mnt/user-data/outputs/patch.json`。
-   基线没有这个 key，不要裁成一条，也不要因为读不到旧数组就丢掉补丁。
-   采集结果是空数组时不要写入，直接告诉用户接口没有可补充的数据。
-3. 之后仍走「表格确认 → fs-detail-update」。合并写入会**新增**这个 key，其它区块保持不变。
-   成功后的回执 `keys` 带上这个新 key。
-
-## 硬约束
-
-- fs-detail-submit（整体替换）只用于"全部重建整份详情"的明确要求，日常修改一律
-  用 fs-detail-update（合并）；缺失区块也用它新增 key，不要改走整体替换；
-- 区块已经有数据时，修改数组必须保留未涉及条目（逐字一致），只交被改那一条属于严重错误；
-  区块缺失或为空时按场景四提交整块新数据，不受这条限制；
-- 各区块字段名与读取结果/信息技能输出逐字一致，不自造；内容保持商业经营主题；
-- 不修改系统文件；中间产物只写 `/mnt/user-data/outputs/`。
