+
+## 核心架构
+
+### 消息通道（EvalChannel）
+- 抽象接口：`send()` / `poll_reply()` / `health_check()`
+- V1 实现：`TutuApiChannel`（HTTP + Bearer Token + questionMsgId 配对）
+- 工厂模式：`ChannelFactory` 按 channel_type 创建实例
+
+### 评测引擎（EvalEngine）
+- 遍历 Scenario.cases → 每个 case 遍历 messages（多轮对话）
+- 发送消息 → 轮询回复 → 记录 Turn → 执行规则 → 保存 EvalResult
+- 支持 `progress_callback` 实时推送事件（WebSocket 集成）
+- 支持 `existing_run` 参数复用已有 run 记录
+
+### 评估规则（EvalRule）
+- `keyword_match`：关键词包含/排除匹配
+- `response_time`：响应时间阈值检查
+- `llm_score`：LLM-as-judge 评分（OpenAI 兼容 API）
+
+### 判定语义（v0.5 起）
+- **期望叠加**：case 的 `expectation` 始终派生隐式 llm_score 规则，与显式规则叠加（隐式是 rule_logic 之外的硬约束，reason 带 `[期望]` 前缀）
+- **连通用例**：无规则且无期望的用例是合法的连通性验证，报告层标注 `connectivity`；`judged_pass_rate` 剔除连通用例，`pass_rate` 口径不变（含执行失败，见 ADR-0002）
+- **场景版本**：`Scenario.version` 系统维护（仅考纲字段变更升版，见 ADR-0001）；运行创建时快照 `EvalRun.scenario_version`，对比报告要求同场景同版本
+
+### 数据模型
+- `EvalTarget` → `EvalRun` ← `Scenario`
+- `EvalRun` → `Turn`（对话轮次）
+- `EvalRun` → `EvalResult`（规则结果）
+
+## 部署知识
+
+### t480 测试服务器
+- **地址**: sola-t480（192.168.8.145）
+- **端口**: 8001（映射容器内 8000）
+- **部署方式**: Docker Compose 双容器（agenteval + openclaw-eval）
+- **Python 镜像**: python:3.11.15-slim-bookworm
+- **APT/Pip 镜像**: 阿里云（绕过 GFW）
+
+### 版本号（单一数据源）
+- **pyproject.toml** 是版本号的唯一来源
+- **package.json** 的版本号由 `scripts/sync_version.py` 自动同步
+- 每次部署前必须运行 `python3 scripts/sync_version.py`（deploy 脚本会自动做）
+- 镜像 tag 同时打 `t480-agenteval:<version>` 和 `t480-agenteval:latest`
+
+### 部署流程（标准）
+```bash
+# 推荐: 一键部署（build/sync/rebuild/verify 全包）
+scripts/deploy-t480.sh
+
+# 仅代码变更（跳过镜像重建, backend 通过 volume 热加载）
+scripts/deploy-t480.sh --skip-build
+
+# 预览命令, 不实际执行
+scripts/deploy-t480.sh --dry-run
+```
+
+脚本会自动:
+1. 同步版本号 `pyproject.toml → package.json`
+2. `npm run build` 构建前端
+3. rsync 代码 + dist 到 t480
+4. `docker compose build --build-arg BUILD_COMMIT=... --build-arg BUILD_TIME=...`
+5. `docker tag t480-agenteval:<version>`
+6. `docker compose up -d`（容器启动时自动跑 `alembic upgrade head`）
+7. curl `/api/health` 验证版本号和 commit 一致
+
+### 部署验证
+```bash
+curl http://192.168.8.145:8001/api/health
+# 返回: {"status":"ok","version":"0.2.0-dev","commit":"abc1234","built_at":"2026-07-14T10:33:41Z"}
+# 如果 version 不匹配本地 pyproject.toml → 部署失败, 脚本会报错退出
+```
+
+### 关键 Volume 挂载
+- `data/` → `/app/data`（SQLite DB + 报告 + openclaw 状态, 可写）
+- `config/config.json` → `/app/config/config.json:ro`
+- `frontend/web/dist/` → `/app/frontend/web/dist:ro`（**必须 build 后再部署**）
+- `backend/` → `/app/backend:ro`（代码热更新）
+- `.env` → `/app/.env:ro`（Pydantic Settings 配置, 见 `.env.example`）
+
+### 鉴权（v0.4 起）
+- `AGENTEVAL_ADMIN_PASSWORD`：设置后 Web UI 需登录（会话 token, 关浏览器失效）；不设则无登录门
+- `AGENTEVAL_API_KEY`：机器调用凭据（X-API-Key）；deploy 脚本会把它写入 openclaw 工作区
+  `data/openclaw/agenteval-api-key`, agenteval-run skill 自动读取
+- 两个凭据任一匹配即放行（`web/deps.py: require_auth`）；`/api/health` 与 `/api/auth/*` 始终开放
+
+### 镜像 tag 约定
+- `t480-agenteval:<version>` — 不可变, 对应某次具体构建
+- `t480-agenteval:latest` — 可变, 总是指向最新部署
+- 回滚: `docker tag t480-agenteval:<old-version> t480-agenteval:latest && docker compose up -d`
+
+## 重要踩坑记录
+
+### 1. SQLite + FastAPI 必须用 StaticPool
+- 默认 QueuePool 在多线程环境下快速耗尽
+- `check_same_thread=False` + `StaticPool` 是 SQLite 的正确配置
+
+### 2. Docker COPY vs Volume 挂载
+- Dockerfile 中 `COPY backend ./backend` 烘焙的代码不会随 rsync 更新
+- 必须通过 volume 挂载 `backend/` 才能实现代码热更新
+- 只有 Dockerfile 或 Python 依赖变更时才需要 `--build`
+
+### 3. Session 生命周期管理
+- 所有 Router 必须使用 `Depends(get_db)` 管理 Session
+- `get_db()` 是 generator，`finally` 中 `session.close()` 确保连接释放
+- 后台任务也需要 `try/finally` 关闭 Session
+
+### 4. EvalEngine.run() 与 API 端点的 run 创建
+- API 端点先创建 run（pending），返回 run_id 给前端
+- 后台任务通过 `existing_run` 参数复用该记录，避免重复创建
+
+### 5. 中国网络环境
+- Docker Hub 和 npm 在国内访问极慢或被墙
+- 使用阿里云 APT/Pip 镜像
+- Clash 代理不可靠时，优先使用镜像策略
+
+### 6. 前端 dist 必须显式构建再部署
+- `frontend/web/dist/` 是构建产物, 不是源码
+- rsync 时如果 `--exclude='frontend/web/dist'`, t480 会一直跑旧 dist, 看起来像"页面回到老版本"
+- 必须 `npm run build` 之后再 rsync, 或者直接用 `scripts/deploy-t480.sh`(自动做这两步)
+- 部署后用 `curl /api/health` 验证 version/commit 和本地一致, 脚本会自动做
+
+### 7. OpenClaw 免登录依赖 Origin 注入
+- OpenClaw 的 `gateway.controlUi.allowedOrigins` 检查 WebSocket 的 Origin header
+- `proxy.py` 必须注入 `origin=http://192.168.8.145:8001`(或 settings.allowed_origins 的第一项)
+- 如果 Origin 缺失, OpenClaw 拒收 WS 连接, SPA 会显示登录页
+- v0.2 起 `openclaw_ws_origin` 从 `allowed_origins` 自动推导, 不再硬编码
+
+## CLI 命令速查
+
+```bash
+agenteval target add --name "名称" --config config/config.json
+agenteval target list
+agenteval target test <id>
+
+agenteval scenario import data/scenarios/xxx.yaml
+agenteval scenario list
+
+agenteval run start --target-id <id> --scenario-id <id>
+agenteval run list
+
+agenteval report show <run-id> --format json
+agenteval report generate <run-id> --format html
+
+agenteval server start --host 0.0.0.0 --port 8000
+```
+
+## 当前数据（t480）
+
+- **评测对象**: 1（社区医院AI客服，tutu-api 通道）
+- **评测场景**: 2（社区医院基础服务评测 + 科室导航与挂号咨询）
+- **API 端点**: `http://192.168.8.145:8001/`
+- **WebSocket**: `ws://192.168.8.145:8001/ws/runs/{run_id}`
+
+## 开发约定
+
+- Python 代码使用 `ruff` 做 lint（line-length 120, target py310）
+- 前端 TypeScript 使用 `tsc --noEmit` 类型检查
+- 文档文件名带版本号（如 `architecture-v1.0.md`）
+- 用户偏好简体中文交互
+
+## CI 检查
+
+- `scripts/ci-check.sh` 一键跑：版本号一致性 + ruff + pytest + tsc（`--fast` 跳过 tsc）
+- 本地 `git push` 会自动触发 pre-push hook 执行 `ci-check.sh --fast`（`.git/hooks/pre-push`，新 clone 需手动重装）
+- Gitea Actions 工作流：`.gitea/workflows/ci.yml`（需 Gitea 实例启用 Actions + 注册 runner 才生效）
+- 紧急绕过：`git push --no-verify`（仅限救急，事后必须补跑）

 ### 关键抽象（均在 `backend/agenteval/`）

- **`channels/base.py`** — `EvalChannel` 抽象：`send()` / `poll_reply()` / `health_check()`；三种实现 `tutu.py`（tutu-api HTTP + Bearer Token）/ `openclaw.py` / `http.py`，`ChannelType` 枚举（`tutu-api` / `openclaw` / `http`）与工厂注册见 `channels/factory.py`
+- **`channels/base.py`** — `EvalChannel` 抽象：`send()` / `poll_reply()` / `health_check()`，V1 实现为 `TutuApiChannel`（tutu-api HTTP + Bearer Token）
 - **`evaluation/engine.py`** — `EvalEngine`：异步执行，遍历 Scenario.cases → messages → 调用 channel → 执行规则 → 写入 DB；通过 `asyncio.Event` cancel_token 支持真取消；`progress_callback` 实时推送事件给 WebSocket
- **`evaluation/rules/`** — `EvalRule` 抽象，注册表（`__init__.py` 导入即注册）已扩到 7 种实现：`keyword.py` / `response_time.py` / `llm_score.py`（LLM-as-judge，支持多维评分）/ `safety.py` / `semantic.py` / `fluency.py` / `json_schema.py`；跨规则隐式逻辑在 `evaluation/implicit_rules.py`
+- **`evaluation/rules/`** — `EvalRule` 抽象，三种实现：`keyword.py`（关键词匹配）、`response_time.py`（延迟阈值）、`llm_score.py`（LLM-as-judge）
 - **`models.py`** — 共享 Pydantic 模型：`EvalTarget` → `EvalRun` ← `Scenario`，`EvalRun` → `Turn` + `EvalResult`
 - **`storage/`** — `db.py`（SQLite StaticPool + SQLModel 表定义）+ `repository.py`（`TargetRepository` / `ScenarioRepository` / `RunRepository` / `ResultRepository`）+ `file_repository.py`（`FileCategoryRepository` / `FileRecordRepository`）
 - **`config/settings.py`** — Pydantic Settings，加载 `AGENTEVAL_` 前缀的环境变量（`.env` 文件），`@lru_cache` 单例
- **`web/deps.py`** — FastAPI 依赖注入：`get_db()`（Session 生命周期管理）、`require_auth()`（鉴权：`X-API-Key` 匹配 `AGENTEVAL_API_KEY` 或 `X-Auth-Token` 匹配 Web 登录会话，任一通过；两个凭据都未配置时 no-op 放行；`require_api_key` 是兼容别名）
+- **`web/deps.py`** — FastAPI 依赖注入：`get_db()`（Session 生命周期管理）、`require_api_key()`（X-API-Key 鉴权）

 **扩展性模式**：
 - **规则注册表**（`evaluation/rules/__init__.py`）：`@register_rule` 装饰器将规则类注册到 `_RULE_REGISTRY`，`get_rule(type, params)` 按名称实例化。添加新规则只需创建类并加装饰器。
 - **通道工厂**（`channels/factory.py`）：`ChannelFactory` 维护 `ChannelType → EvalChannel` 映射，`register()` 类方法支持插件式注册新通道类型。

-### 判定与报告口径
-
-通过率/判定口径是跨版本演进的敏感点（v0.5 判定语义 → v1.3 go/no-go），改动前先读相关 ADR，避免与报告层分叉：
- case 判定在 `evaluation/case_verdict.py`；run 级汇总在 `evaluation/run_summary.py`——`judged_pass_rate` 剔除连通用例、`pass_rate` 含执行失败（ADR-0002/0004）
- 隐式期望规则（期望叠加）在 `evaluation/implicit_rules.py`；go/no-go 判定在 `evaluation/go_no_go.py`
- 术语与口径基线见 `CONTEXT.md`
-
 ### API 端点 / Run 生命周期

 `POST /api/runs` → API 先创建 `pending` 状态的 run，返回 run_id → 后台 `asyncio.Task` 调用 `EvalEngine.run(existing_run=...)` 复用该记录 → `ws://…/ws/runs/{run_id}` 推送实时进度。

-### 智能评估执行机制（方案③触发式执行，ADR-0009/0010/0011/0012）
-
-Worker 自动化由平台掌控节奏：`web/app.py` lifespan 只做 `scheduler_runtime.start()/stop()`，实际循环在 `intelligent_eval/scheduler.py`——每 60s（`SCAN_INTERVAL_SECONDS`）执行一次 `scan_once()`，单个节拍依次：
-
-1. **requeue_stale_assigned_tasks**（task_queue.py）：assigned 超时（>10min）且评估 executing → 回 pending（卡死恢复）
-2. **expire_stale_running_sessions**：running 会话 60min 无新轮次 → expired
-3. **watchdog 判死**：planning 双闸 / executing 超窗 / 连续触发失败超限 → failed
-4. **scan_and_enqueue_tasks**：扫描 executing 评估，按时段到期 + 欠账（`domain.py::get_attention_reason`）→ 入队（每评估去重一条 pending/assigned）
-5. **settle_tasks_for_finished_evals**：评估离开 executing 后，其 pending/assigned 任务回收为 completed
-6. **supplement_decision_logs**：agent 未上报决策日志时按状态兜底补录（审计）
-7. **analyst 催促**：末会话终态 10min 后落账 nudge，交给 worker 触发转 analyst 汇总报告
-8. **触发**：fire-and-forget（不阻塞 60s 节拍）唤醒 worker / planner
-
-关键约束（改动此机制前必读）：
- **触发原语**：`docker exec openclaw-eval timeout 600 openclaw agent --agent main --session-id <prefix>-<ts> -m <msg> --json`，subprocess 侧 timeout 660
- **独立 session**：session-id 形如 `agenteval-worker-<ts>` / `agenteval-planner-<ts>`，**禁止复用 `--agent main` 的持久 session**——main session 多次触发累积上下文缓存（~12 万 token）后 worker 会幻觉输出而不执行 API 步骤（ADR-0010）
- **时段分布**：触发消息强制"仅执行当前时间对应时段（time_distribution）内欠账的会话"，绝不创建未来时段会话——未来时段由后续 60s 节拍再次触发；所有时段会话到终态才转 analyst
- **状态一致性**：`submit_report` 要求会话全部 close 才允许 completed（`intelligent_eval/lifecycle/report_submission.py`）；per-eval 触发冷却 10min 防 60s 节拍堆叠并发 agent
-
-### 扩展域速览（v1.1+ 新增域，早期架构文档未覆盖）
-
- **Campaigns（评估活动）**：`evaluation/campaign_{lifecycle,runner,scheduler,read_model,report}.py` + `models.py` 的 `CampaignDB`；路由在 `web/routers/campaigns.py`；跨 run 聚合见 `comparison.py` / `analysis.py` / `go_no_go.py` / `cost_tracking.py`；后台任务登记在 `task_registry.py`
- **IntelligentEvals（智能评估域）**：`intelligent_eval/`——`domain.py`（优先级/注意力）、`lifecycle/`（状态机，终止态纪律见 ADR-0011/0012）、`task_queue.py`、`decision_logs.py`、`config_snapshot.py`、`read_model.py` / `report.py`；软删语义只在 `repository.py`（见陷阱 6）
- **Exploration（探索巡检）**：`exploration/patrol.py`（巡检）+ `judge.py` + `summary.py`，自带 models/errors/lifecycle

- `CONTEXT.md` — 领域术语唯一词汇表
- `docs/adr/` — 关键架构决策
- `docs/agents/` — AI 协作工作流（Gitea Issues / triage 标签 / 领域文档约定）
- `CHANGELOG.md` — 版本历史
+**AgentEvalTool** 是智能体质量评估工具集平台（v0.2.0），用于评估 AI 数字员工（tutu-api 通道）和 AI 助手（OpenClaw）的服务质量。Python 3.11 后端 + TypeScript/React 前端，SQLite 持久化。

-需要更新项目知识时，改 `AGENTS.md`，不要改本文件。
+## 常用命令
+
+### 后端
+
+```bash
+# 安装（含 dev 依赖）
+pip install -e ".[dev]"
+
+# 启动 Web 后台
+agenteval server start --host 0.0.0.0 --port 8000
+
+# 运行全部测试
+pytest
+
+# 运行单个测试文件
+pytest tests/unit/test_engine.py -v
+
+# 运行带覆盖率的测试
+pytest --cov=backend/agenteval --cov-report=term-missing
+
+# Lint
+ruff check backend/
+ruff format backend/
+```
+
+### 前端
+
+```bash
+cd frontend/web
+npm install
+npm run dev        # 开发服务器
+npm run build      # 构建生产产物（部署前必须执行）
+npx tsc --noEmit   # 类型检查
+```
+
+### 数据库迁移
+
+```bash
+alembic upgrade head   # 升级到最新
+alembic revision --autogenerate -m "描述"  # 生成新迁移
+```
+
+注意：`init_db()` 调用 `SQLModel.metadata.create_all()` 直接建表（用于全新 DB），Alembic 用于已有 DB 的增量变更。`migrations/env.py` 设置了 `render_as_batch=True`（SQLite 不支持 ALTER TABLE，batch mode 通过重建表来模拟）。
+
+### 部署（t480）
+
+```bash
+scripts/deploy-t480.sh             # 一键部署（推荐）
+scripts/deploy-t480.sh --skip-build  # 仅代码变更，跳过镜像重建
+scripts/deploy-t480.sh --dry-run   # 预览命令
+```
+
+## 核心架构
+
+### 三层结构
+
+```
+CLI (Typer) / Web API (FastAPI)
+        ↓
+EvalEngine（异步评测执行引擎）
+        ↓ 通过抽象接口
+EvalChannel → 消息通道（TutuApiChannel）
+EvalRule    → 评估规则（keyword_match / response_time / llm_score）
+        ↓
+SQLite Storage（Repository 模式）
+```
+
+### 关键抽象（均在 `backend/agenteval/`）
+
+- **`channels/base.py`** — `EvalChannel` 抽象：`send()` / `poll_reply()` / `health_check()`，V1 实现为 `TutuApiChannel`（tutu-api HTTP + Bearer Token）
+- **`evaluation/engine.py`** — `EvalEngine`：异步执行，遍历 Scenario.cases → messages → 调用 channel → 执行规则 → 写入 DB；通过 `asyncio.Event` cancel_token 支持真取消；`progress_callback` 实时推送事件给 WebSocket
+- **`evaluation/rules/`** — `EvalRule` 抽象，三种实现：`keyword.py`（关键词匹配）、`response_time.py`（延迟阈值）、`llm_score.py`（LLM-as-judge）
+- **`models.py`** — 共享 Pydantic 模型：`EvalTarget` → `EvalRun` ← `Scenario`，`EvalRun` → `Turn` + `EvalResult`
+- **`storage/`** — `db.py`（SQLite StaticPool + SQLModel 表定义）+ `repository.py`（`TargetRepository` / `ScenarioRepository` / `RunRepository` / `ResultRepository`）+ `file_repository.py`（`FileCategoryRepository` / `FileRecordRepository`）
+- **`config/settings.py`** — Pydantic Settings，加载 `AGENTEVAL_` 前缀的环境变量（`.env` 文件），`@lru_cache` 单例
+- **`web/deps.py`** — FastAPI 依赖注入：`get_db()`（Session 生命周期管理）、`require_api_key()`（X-API-Key 鉴权）
+
+**扩展性模式**：
+- **规则注册表**（`evaluation/rules/__init__.py`）：`@register_rule` 装饰器将规则类注册到 `_RULE_REGISTRY`，`get_rule(type, params)` 按名称实例化。添加新规则只需创建类并加装饰器。
+- **通道工厂**（`channels/factory.py`）：`ChannelFactory` 维护 `ChannelType → EvalChannel` 映射，`register()` 类方法支持插件式注册新通道类型。
+
+### API 端点 / Run 生命周期
+
+`POST /api/runs` → API 先创建 `pending` 状态的 run，返回 run_id → 后台 `asyncio.Task` 调用 `EvalEngine.run(existing_run=...)` 复用该记录 → `ws://…/ws/runs/{run_id}` 推送实时进度。
+
+**WebSocket 事件类型**（`/ws/runs/{run_id}`，由 `ConnectionManager.emit()` 广播）：
+
+| 事件 | 触发时机 | payload |
+|------|---------|---------|
+| `case_start` | 开始评测一个 case | `{case_id, case_index, total_cases}` |
+| `messages_generated` | 动态 case 的 AI 生成消息完成 | `{case_id, messages}` |
+| `turn_start` | 开始发送一轮对话 | `{case_id, turn_index}` |
+| `turn_end` | 收到回复 | `{case_id, turn_index, reply, latency_ms}` |
+| `turn_error` | 发送或接收失败 | `{case_id, turn_index, error}` |
+| `rule_result` | 单条规则评估完成 | `{case_id, turn_index, rule_type, passed, score, reason}` |
+| `case_end` | case 评测完成 | `{case_id, passed, score, error?}` |
+| `run_completed` | 整个 run 完成 | `{run_id, status}` |
+| `error` | case 级或 run 级错误 | `{case_id?, message}` |
+
+前端 `sessionReducer.ts` 的 `WS_EVENT` action 处理以上所有事件类型。
+
+### OpenClaw 代理
+
+后端通过 `routers/proxy.py` 提供 HTTP + WebSocket 反向代理（路径前缀 `/openclaw`），将请求转发到 OpenClaw 服务（docker-compose 中 `openclaw-eval` 容器）。WS 桥接会自动注入认证 token 到 `connect.authenticate` 消息并重写 `Origin` 头。前端 `/openclaw` 路由以全屏 iframe 嵌入代理地址。
+
+### 智能评估执行机制（方案③触发式执行）
+
+智能评估的 Worker 自动化（取代旧 Cron 池，见 ADR-0009/0010）由 `app.py::_intelligent_eval_scan_loop` 驱动（lifespan 后台任务，每 60s）：
+
+1. **requeue_stale_assigned_tasks**：assigned 超时（>10min）且评估 executing → 回 pending（卡死恢复）
+2. **scan_and_enqueue_tasks**：扫描 executing 评估，时段到期/欠账 → 入队（任务队列）
+3. **settle_tasks_for_finished_evals**：评估离开 executing 后，其 pending/assigned 任务回收为 completed
+4. **_supplement_decision_logs**：agent 未上报决策日志时按状态兜底补录
+5. **触发**：有 planning 评估 → 触发 planner skill；有 pending 任务 → 触发 worker skill
+
+关键约束：
+- **独立 session**：触发命令必须带 `--session-id`（`agenteval-worker-<ts>` / `agenteval-planner-<ts>`），**禁止复用 `--agent main` 的持久 session**——main session 多次触发累积上下文缓存后 worker 会幻觉不执行（见 ADR-0010）
+- **时段分布**：触发指令明确"仅执行当前到期时段内欠账的会话"，平台每 60s 持续触发推进后续时段，保证 1h 窗口按时段分批
+- **状态一致性**：`submit_report` 要求会话全部 close 才允许 completed；worker 触发 timeout 600s
+
+### 文件管理模块
+
+`/api/files` 端点提供分类树 + 文件上传/下载功能。`FileCategoryDB` 自引用（`parent_id`）实现树形结构，`FileRecordDB` 关联分类。文件物理存储在 `data/uploads/`，按分类子目录组织。删除分类会级联删除子分类 + 文件记录 + 物理文件。
+
+### 前端
+
+SPA 由 FastAPI 托管（`GET /{full_path:path}` → `index.html`）。`frontend/web/src/api.ts` 是所有接口定义的单一出口，axios 拦截器统一处理错误。`useRunSession.ts` hook 管理 WebSocket 实时状态。
+
+**路由采用 keep-alive 标签页模式**（非标准 `<Routes>`）：所有页面同时挂载在 DOM 中，通过 `display: block/none` 切换可见性，保证页面状态在切 tab 时不丢失。路由配置集中在 `App.tsx` 的 `routeConfigs` 数组中，Zustand `tabStore` 管理标签页的打开/关闭/激活状态，`react-router` 仅用于 URL 同步。
+
+**三种状态管理策略**：
+- **Zustand**（`stores/tabStore.ts`）：全局标签页状态，唯一一个 store
+- **useReducer**（`hooks/sessionReducer.ts`）：评测会话状态（cases/turns/results/progress），纯 reducer 无副作用，hook 负责 WS/REST 副作用
+- **useState**：各页面本地数据，无全局缓存（不使用 SWR/React Query）
+
+**Vite 开发代理**：dev server 端口 3000，`/api`、`/ws`、`/openclaw` 全部代理到 `localhost:8000`；生产构建时 `dist/` 由 FastAPI 直接托管。
+
+**Ant Design CSS-in-JS 冲突**：Ant Design v5 的 emotion 运行时注入会覆盖静态 CSS 的 `flex`/`height` 规则。Runs 页采用"导航与内容分离"方案——Tabs 组件仅用于渲染导航头（`.nav-only-tabs` CSS 隐藏 `.ant-tabs-content-holder`），实际内容 div 由 flex 直接控制高度，绕过 Ant Design 内部 DOM。
+
+**构建注意**：`@monaco-editor/react` 独立拆分为 `vendor-monaco` chunk（`vite.config.ts` 的 `manualChunks`）。设计 Token 在 `tokens.ts` 集中管理（组件直接 import，非 CSS 变量方案）。
+
+## 开发约定
+
+- **版本号单一数据源**：`pyproject.toml` → 由 `scripts/sync_version.py` 同步到 `package.json`，部署脚本自动执行
+- **Python lint**：ruff，line-length 120，target py310
+- **前端类型检查**：`tsc --noEmit`
+- **文档文件名**带版本号，如 `architecture-v1.0.md`
+- **SQLite 必须用 `StaticPool` + `check_same_thread=False`**，否则多线程下连接耗尽
+- **所有 Router 用 `Depends(get_db)` 管理 Session**，后台任务也需 `try/finally` 关闭
+- **`frontend/web/dist/`** 是构建产物，部署前必须 `npm run build`，否则 t480 跑旧版
+
+## 配置
+
+- `.env`（参考 `.env.example`）：`AGENTEVAL_API_KEY`（X-API-Key 鉴权）、`AGENTEVAL_ALLOWED_ORIGINS`（CORS，首个非 localhost URL 用作 OpenClaw WS Origin）、`AGENTEVAL_OPENCLAW_*` 系列（代理上游地址 + 认证 token）
+- `config/config.json`：tutu-api 通道配置（敏感信息，只读挂载到容器）
+- 无 CI/CD，部署依赖手动执行 `scripts/deploy-t480.sh`
+
+## 测试结构

+
+### Triage labels
+
+Triage 使用五个默认角色标签。详见 `docs/agents/triage-labels.md`。
+
+### Domain docs
+
+仓库采用单一上下文：根目录 `CONTEXT.md` 配合 `docs/adr/`。详见 `docs/agents/domain.md`。
+
+## 部署关键信息
+
+- **t480**：`sola-t480`（192.168.8.145:8001），Docker Compose **双容器**（`agenteval` + `openclaw-eval`）
+- **端口映射**：主机 8001 → 容器 8000（主机 8000 已被占用）
+- **健康检查**：`curl http://192.168.8.145:8001/api/health` 返回 version/commit，脚本验证与本地 `pyproject.toml` 一致
+- **回滚**：`docker tag t480-agenteval:<old-version> t480-agenteval:latest && docker compose up -d`
+- **backend/ 通过 volume 热加载**，只有 Python 依赖变更才需要 `--build`
+- **前端 dist/ 也通过 volume 挂载**，因此每次前端变更也需要重新构建（`./scripts/deploy-t480.sh` 自动处理）
+- **openclaw-eval** 容器使用 `ghcr.io/openclaw/openclaw:latest` 镜像，通过 `AGENTEVAL_API_URL` 环境变量连接 agenteval
+
+## 已知陷阱
+
+1. **`index.css` 必须显式 import**：Vite 不会自动包含未被引用的 CSS。`main.tsx` 必须有 `import './index.css'`，否则全局样式（动画、布局覆盖、nav-only-tabs）全部无效且无报错。这是历史遗留 bug（项目创建以来就缺失），已修复但容易在重构时再次丢失。
+
+2. **UTC 时间戳解析**：后端返回的 datetime 字符串不含时区标记（如 `"2026-07-14T16:40:00"`），JS 的 `new Date()` 会按本地时间解析导致偏差 8 小时。前端必须使用 `utils/date.ts` 的 `toDate()` 函数（检测并追加 `Z` 后缀），禁止直接 `new Date(str)`。根本修复需后端序列化时附带时区。
+
+3. **Ant Design CSS-in-JS 覆盖**：Ant Design v5 的 emotion 运行时注入优先级高于静态 CSS 文件中的 `flex`/`height`/`overflow` 规则。需要弹性布局的容器避免依赖 `.ant-tabs-content` 等 Ant 内部 DOM，改用导航与内容分离方案。见上方前端架构说明。
+
+4. **SQLite 连接池**：必须用 `StaticPool` + `check_same_thread=False`。使用默认连接池会导致多线程下连接耗尽（async + FastAPI 线程池混合场景）。
+
+5. **`.env` 在 t480 上需手动维护**：部署脚本不会自动同步 `.env` 文件，新增环境变量需 SSH 到主机手动补全。容易导致 OpenClaw 代理等功能静默失效。
