-# Copilot Instructions for TJWaterFrontend_Refine
-
-## Environment Setup
-
-1. **Node.js**: Ensure you have Node.js v18 or later installed.
-2. **Dependencies**: Run `npm install` to install all project dependencies.
-3. **Environment Variables**: Create a `.env.local` file in the root directory with
-
-Using bash setup dependencies:
-
-```bash
-npm install
-```
-
-## Build, Test, and Lint
-
- **Dev Server**: `npm run dev` (Runs with increased memory limit: `--max_old_space_size=4096`)
- **Build**: `npm run build`
- **Lint**: `npm run lint` (ESLint)
- **Test**: `npm run test` (Jest)
-  - Run a specific test file: `npm run test -- <path/to/file>`
-  - Run a specific test case: `npm run test -- -t 'test name'`
-
-## High-Level Architecture
-
- **Framework**: **Next.js 16 (App Router)** integrated with **Refine** (`@refinedev/core`).
- **Routing**:
-  - Routes are defined in `src/app`.
-  - Refine resources (e.g., `/network-simulation`, `/hydraulic-simulation/*`) map directly to these routes.
-  - Configuration is central in `src/app/_refine_context.tsx`.
- **State Management**:
-  - **Global App State**: **Zustand** (`src/store`).
-  - **Server State**: Managed by Refine hooks (`useList`, `useOne`, etc.) via **React Query**.
- **Authentication**:
-  - **NextAuth.js** handling Keycloak integration.
-  - Session token is synced to Zustand (`useAuthStore`) in `RefineContext`.
- **Data Layer**:
-  - Custom Data Provider: `src/providers/data-provider`.
-  - API Utilities: `src/lib/api.ts`, `src/lib/apiFetch.ts`.
- **UI & Styling**:
-  - **Material UI (MUI)**: Primary component library (`@mui/material`, `@refinedev/mui`).
-  - **Tailwind CSS v4**: Utility classes for layout and custom styling (`@tailwindcss/postcss`).
-  - **Mapping**: OpenLayers (`ol`), deck.gl, Turf.js.
-  - **Charts**: ECharts, MUI X Charts.
-
-## Key Conventions
-
- **Refine Integration**:
-  - Use Refine hooks (`useTable`, `useForm`, `useNavigation`) for data-heavy components.
-  - Resources are defined in the `<Refine>` component in `src/app/_refine_context.tsx`.
- **Project Structure**:
-  - `src/components/`: Grouped by feature (e.g., `olmap`, `project`) or common UI elements.
-  - `src/lib/`: Utility functions and API helpers.
-  - `src/providers/`: Refine providers (data, etc.).
- **Imports**:
-  - Use absolute imports with `@/` alias (e.g., `@/components`, `@/store`, `@/lib`).
-  - _Note_: `@libs` alias in tsconfig points to non-existent `src/libs` folder; prefer `@/lib`.
- **Styling**:
-  - Prefer MUI components for standard UI elements.
-  - Use Tailwind utility classes for layout and custom overrides.

+# Repository Guidelines
+
+## Project Structure & Module Organization
+
+This repository is the TJWater web frontend built with Refine, Next.js, React, and MUI. Application source lives under the existing Next.js project folders. Reuse established page, component, provider, map, and chat patterns instead of adding parallel structures. Static assets and public files should remain in the existing asset/public locations. Build output (`.next/`), dependency folders, and local caches are generated and must not be edited by hand.
+
+Deployment files are `Dockerfile`, `docker-compose.yml`, and `.gitea/workflows/package.yml`.
+
+## Build, Test, and Development Commands
+
+Use npm and Node 20 or newer:
+
+```bash
+npm install
+npm run dev
+npm run lint
+npm test
+npm run test:coverage
+npm run build
+npm run start
+```
+
+`npm run dev` starts the Refine/Next development server. `npm run lint` runs ESLint. `npm test` runs Jest. `npm run build` creates the production build.
+
+## Coding Style & Naming Conventions
+
+Use TypeScript and React function components. Follow ESLint and Next.js conventions. Use `PascalCase` for React component files and component names. Use `camelCase` for ordinary TypeScript modules, hooks, stores, providers, utilities, variables, and functions. Next.js route directories under `src/app` use `kebab-case`; route groups and dynamic segments keep the Next.js syntax such as `(main)` and `[...nextauth]`. Keep backend/Agent boundary fields and query parameters in the shape required by the API, typically `snake_case`, and do not translate third-party SDK fields. Prefer MUI components and existing design tokens/patterns for UI. Keep operational screens dense, clear, and task-focused.
+
+## Testing Guidelines
+
+Tests use Jest with React Testing Library. Name tests `*.test.ts` or `*.test.tsx` near the related code when possible. Add tests for user-visible behavior, state transitions, route guards, data transforms, and map/chat interactions. Run `npm test` or `npm run test:coverage` before larger PRs.
+
+## Commit & Pull Request Guidelines
+
+History uses Conventional Commit messages such as `feat(map): add coordinate zoom action` and `fix(chat): hide raw permission metadata`, with occasional Chinese summaries. Prefer `feat(scope):`, `fix(scope):`, or `refactor(scope):`.
+
+PRs should include a UI/behavior summary, verification commands, screenshots for visual changes, and notes for changed environment variables or backend API expectations.
+
+## Security & Configuration Tips
+
+Do not commit `.env`, `.next/`, `node_modules/`, local caches, or private map/API tokens. Public build-time variables should be documented; sensitive values belong in Gitea secrets.

+# Frontend Naming Audit
+
+DOC-004 audit for the internal `TJWaterFrontend_Refine` application.
+
+## Local frontend naming
+
+- Next.js route directories under `src/app` are already `kebab-case`: `audit-logs`, `health-risk-analysis`, `hydraulic-simulation`, `monitoring-place-optimization`, `network-simulation`, `scada-data-cleaning`, and `system-admin`.
+- Route groups and dynamic segments keep Next.js syntax: `(main)` and `[...nextauth]`.
+- Local ordinary module filenames now use `camelCase`, including `src/utils/breaksClassification.ts`, `src/components/chat/globalChatboxUtils.ts`, and `src/components/chat/globalChatboxVoice.ts`.
+- React component files remain `PascalCase.tsx`, including `src/app/RefineContext.tsx`, `src/components/chat/GlobalChatboxParts.tsx`, and domain directories under `src/components/olmap`.
+
+## API boundary naming
+
+Frontend request and response boundary fields intentionally keep backend/Agent wire names. Examples include `project_id`, `user_id`, `scheme_name`, `scheme_type`, `start_time`, `end_time`, `session_id`, `request_id`, and `keep_message_count`.
+
+Current direct API calls mostly use new `kebab-case` URL paths, including:
+
+- `/api/v1/admin/projects`
+- `/api/v1/audit/logs`
+- `/api/v1/projects/open`
+- `/api/v1/project-info`
+- `/api/v1/schemes`
+- `/api/v1/sensor-placement-schemes`
+- `/api/v1/burst-analysis`
+- `/api/v1/valve-isolation-analysis`
+- `/api/v1/flushing-analysis`
+- `/api/v1/contaminant-simulation`
+- `/api/v1/simulations/run-by-date`
+- `/api/v1/burst-detection/detect`
+- `/api/v1/burst-location/locate`
+- `/api/v1/scada/by-ids-field-time-range`
+- `/api/v1/composite/clean-scada`
+- `/api/v1/agent/chat/render-ref/{render_ref}`
+
+## Legacy URL inventory
+
+The frontend no longer calls these active legacy URLs directly. The backend still exposes them as deprecated compatibility aliases:
+
+| Current frontend URL | Files | Suggested target |
+| --- | --- | --- |
+| `/api/v1/openproject/` | `src/contexts/ProjectContext.tsx` | `/api/v1/projects/open` or `/api/v1/project/open` |
+| `/api/v1/project_info/` | `src/contexts/ProjectContext.tsx` | `/api/v1/project-info` |
+| `/api/v1/getallschemes/` | burst, burst simulation, contaminant, flushing scheme query components | `/api/v1/schemes` |
+| `/api/v1/getallsensorplacements/` | `src/components/olmap/MonitoringPlaceOptimization/SchemeQuery.tsx` | `/api/v1/sensor-placement-schemes` |
+| `/api/v1/sensorplacementscheme/create` | `src/components/olmap/MonitoringPlaceOptimization/OptimizationParameters.tsx` | `/api/v1/sensor-placement-schemes` |
+| `/api/v1/burst_analysis/` | `src/components/olmap/BurstSimulation/AnalysisParameters.tsx` | `/api/v1/burst-analysis` |
+| `/api/v1/valve_isolation_analysis/` | `src/components/olmap/BurstSimulation/ValveIsolation.tsx` | `/api/v1/valve-isolation-analysis` |
+| `/api/v1/flushing_analysis/` | `src/components/olmap/FlushingAnalysis/AnalysisParameters.tsx` | `/api/v1/flushing-analysis` |
+| `/api/v1/contaminant_simulation/` | `src/components/olmap/ContaminantSimulation/AnalysisParameters.tsx` | `/api/v1/contaminant-simulation` |
+| `/api/v1/runsimulationmanuallybydate/` | `src/components/olmap/core/Controls/Timeline.tsx` | `/api/v1/simulations/run-by-date` |
+
+Already migrated frontend code leaves comments showing older pre-`/api/v1` URLs in `src/components/olmap/core/Controls/Toolbar.tsx`; those comments are historical only and are not active calls.
+
+## Follow-up
+
+Continue tracking broad passive legacy backend routes under the shared legacy API compatibility strategy.

 ```

-### Running the production server.
+`npm run dev` 会先执行运行时配置生成，再启动 Next.js 开发服务。
+
+## 常用命令

 ```bash
-    npm run start
+npm run lint
+npm test
+npm run test:coverage
+npm run build
+npm run start
+docker build -t tjwater-frontend:local .
 ```

-## Learn More
+- `npm run lint`：运行 ESLint。
+- `npm test`：运行 Jest。
+- `npm run test:coverage`：生成测试覆盖率。
+- `npm run build`：生成生产构建。
+- `npm run start`：启动生产模式服务。

-To learn more about **Refine**, please check out the [Documentation](https://refine.dev/docs)
+## 配置说明

- **REST Data Provider** [Docs](https://refine.dev/docs/core/providers/data-provider/#overview)
- **Material UI** [Docs](https://refine.dev/docs/ui-frameworks/mui/tutorial/)
- **Custom Auth Provider** [Docs](https://refine.dev/docs/core/providers/auth-provider/)
+运行时配置由 `scripts/generate-runtime-config.mjs` 生成。API 地址、Agent 地址、Keycloak/认证参数、地图服务地址和其他环境差异配置应通过环境变量或部署配置注入。

-## License
+只有允许暴露给浏览器的配置才应进入 public/runtime 配置；密钥和私有 token 不能进入前端构建产物。

-MIT
+## 开发规范
+
+- React 组件文件使用 `PascalCase.tsx`。
+- 普通 TypeScript 模块、hooks、store、provider 和工具使用 `camelCase.ts`。
+- `src/app` 路由目录使用 `kebab-case`，保留 Next.js 路由组和动态段语法。
+- UI 优先沿用 MUI、Refine 和既有地图/聊天界面模式。
+- 与后端或 Agent 通信的字段保持接口原始格式，通常为 `snake_case`。
+
+## 测试与发布
+
+提交前建议运行：
+
+```bash
+npm run lint
+npm test
+```
+
+发布镜像前运行：
+
+```bash
+npm run build
+```
+
+Gitea 包工作流位于 `.gitea/workflows/package.yml`，通常由 tag 触发构建和推送镜像。
+
+## 安全规则
+
+不要提交 `.env`、`.next/`、`node_modules/`、本地缓存、私有地图/API token、客户数据或部署密钥。CI/CD 凭据应放在 Gitea secrets 中。

+- 已生成内容必须稳定，不能反复淡入、重排或闪烁。
+- 图表和工具调用插入时不能让“分析结果”边框剧烈抖动。
+- 底部自动滚动要跟随，但不能每个 token 都强制贴底。
+- 动画应辅助理解，不能比内容本身更抢眼。
+
+## 文本流式生成
+
+### 经验结论
+
+不要把后端 token 到达节奏直接暴露给 UI。后端 token 通常不均匀，前端如果每个 token 都立即渲染，会出现文字跳动、滚动频繁、动画看不出来等问题。
+
+更稳的做法是类似 Vercel AI SDK `smoothStream` 的思路：
+
+- token 先进入缓冲区。
+- 前端按固定节奏释放 chunk。
+- chunk 尽量按词、短语、标点边界切分。
+- 当缓冲积压较大时，自适应加快 drain，避免显示落后真实输出太多。
+
+当前实现采用：
+
+- `TOKEN_PLAYBACK_INTERVAL_MS = 16`
+- 小缓冲按较短 chunk 输出。
+- 大缓冲最多每帧释放 `160` 字符。
+- 中文优先使用 `Intl.Segmenter("zh", { granularity: "word" })`。
+- 非 token 事件前强制 flush，保证工具调用、done、error 的顺序正确。
+
+### 踩坑
+
+- 只做 `setTimeout(120ms)` 批量 flush 不够。它只是减少更新次数，并不能形成稳定播放节奏。
+- interval 太小，例如 `8ms`，浏览器调度不一定更稳定，反而可能增加 React 更新压力。
+- 中文按 `Intl.Segmenter` 的单个词输出会显得慢，必须结合缓冲长度动态放大 chunk。
+- `done`、`error`、`tool_call` 前如果不 flush，会造成文本和结构事件顺序错乱。
+
+## Markdown 动画
+
+### 经验结论
+
+Markdown 是流式文本动画里最容易出问题的部分。原因是 `ReactMarkdown` 每次都会重新解析完整内容，原始 Markdown 字符索引和最终 DOM 文本节点索引不一致。
+
+典型例子：
+
+- `**加粗**` 的原始长度包含 `**`，但可见文本不包含。
+- 列表符号、链接语法、代码块围栏都可能影响原始索引。
+- 新增文本可能落在 `p`、`li`、`strong`、`code` 等不同节点里。
+
+因此不要简单用原始 `text.length` 或 `fadeFrom` 去对应 Markdown 渲染后的 DOM 文本。
+
+当前策略：
+
+- Markdown 仍完整解析，保证格式正确。
+- 在 rehype 阶段处理 AST。
+- 从 AST 尾部反向找最后的可见 text node。
+- 只给最后一段尾部文本加动画。
+- 每次最多动画最后 `48` 个字符，避免大 chunk 整段闪烁。
+
+### 踩坑
+
+- 用 `text.length` 作为 React key 会导致整段 Markdown remount，所有文本都会重新淡入。
+- CSS animation 和 Web Animations 同时作用在同一个 span 上，会出现闪烁或动画重启。
+- 在 render 阶段读写 ref 会触发 React hooks lint 规则，也容易产生不可控渲染。
+- 反向遍历 AST 时拆分 text node 要注意顺序。使用 `unshift` 时应先插入动画尾巴，再插入稳定文本，最终 DOM 才是“稳定文本在前，动画尾巴在后”。
+
+## 当前文字动画建议
+
+推荐保留轻量动画：
+
+- 使用 Web Animations，在 `useLayoutEffect` 中启动，避免先完整显示一帧再裁切。
+- 使用 `clip-path` 做左到右 reveal。
+- 叠加轻微 opacity：当前约 `0.46 -> 1`。
+- 时长控制在 `120ms - 260ms`。
+
+不要做：
+
+- 外层整段 `motion.div` 淡入。
+- 每次流式更新都改变 key。
+- 对整个 Markdown AST 的新增范围大面积包 span。
+- 在生成中对已有文本重复动画。
+
+## 滚动和边框稳定
+
+### 经验结论
+
+滚动条在最底部时，内容增长会不断改变 `scrollTop`。如果每个 token 都执行 `scrollTop = scrollHeight` 或 `scrollIntoView`，最后一个 assistant turn 的边框会产生明显抖动。
+
+当前策略：
+
+- 生成中不再每个 token 精确贴底。
+- 底部保留生成缓冲区，当前约 `180px`。
+- 只有缓冲被消耗到阈值后才恢复滚动。
+- 用户离开底部附近后，不再强制自动跟随。
+- 使用 `scrollbar-gutter: stable` 减少滚动条出现/消失造成的宽度变化。
+
+### 踩坑
+
+- “锁最大高度”不是正确方向。问题不是高度无限增长，而是底部锚定过于频繁。
+- 每 token 自动滚动会把视口不断向下推，视觉上就是边框抖动。
+- 滚动判断阈值要和底部缓冲一致，否则缓冲刚出现就被判断为“离开底部”。
+
+## 图表生成
+
+### 经验结论
+
+图表不能等数据到达后突然插入。图表生成应先占位，再 crossfade，再让图表内部动画接管。
+
+当前策略：
+
+- 工具调用 pending 时使用固定尺寸 `ChartGenerationSkeleton`。
+- 图表真实数据到达后，继续短暂保留 skeleton overlay。
+- ECharts 在 skeleton 下方淡入。
+- 容器尺寸保持一致，避免边框高度突变。
+- ECharts 内部使用 enter/update 动画，而不是外层布局动画。
+
+图表类型动画建议：
+
+- 折线图：平滑 enter，面积渐显。
+- 柱状图：柱子从基线增长，并对数据点轻微 stagger。
+- 饼图：使用 expansion/sweep 类进入动画。
+- update 动画要短于 enter 动画。
+
+### 踩坑
+
+- 只给外层图表卡片 fade in 不够，插入瞬间仍可能造成内容跳变。
+- skeleton 和最终图表尺寸不一致，会导致边框先长再缩。
+- 图表更新时不要重建组件，尽量让 ECharts diff 数据并执行内部 transition。
+
+## 状态提示
+
+“正在生成”状态是有价值的，应该保留。它承担了部分动感和系统状态反馈，不需要让文本动画本身过于夸张。
+
+推荐：
+
+- 状态放在“分析结果”标题行右侧。
+- 使用小尺寸、低干扰的 pulsing dots。
+- 不使用末尾光标，避免和业务文本混在一起。
+
+## 验证建议
+
+每次调整流式动画后至少跑：
+
+```bash
+npx eslint src/components/chat/AgentMarkdownBlock.tsx src/components/chat/AgentTurn.tsx src/components/chat/ChatInlineChart.tsx src/components/chat/AgentWorkspace.tsx src/components/chat/GlobalChatbox.tsx src/components/chat/hooks/useAgentChatSession.ts
+npx tsc --noEmit
+npm test -- src/components/chat/hooks/useAgentChatSession.lifecycle.test.tsx src/components/chat/hooks/useAgentChatSession.actions.test.tsx src/components/chat/AgentWorkspace.test.tsx src/components/chat/ChatInlineChart.test.ts --runInBand
+```
+
+人工验证重点：
+
+- 长中文回答是否明显落后后端真实速度。
+- Markdown 加粗、列表、代码块是否乱序。
+- 底部自动滚动时“分析结果”边框是否抖动。
+- 工具调用 pending 到图表出现时是否有高度跳变。
+- 用户手动上滚后是否停止强制跟随。
+
+## 后续调整原则
+
+1. 先调节 token playback，再调动画。
+2. 动画只作用于新增内容，已有内容不能重播。
+3. Markdown 动画优先保守，宁可弱一点，也不能破坏文本顺序。
+4. 图表和工具调用先稳定布局，再考虑视觉效果。
+5. 滚动跟随要有缓冲，不能逐 token 贴底。
