fix: 算力节点任务/GPU 统计纳入评测与推理占用，补充测试依赖

- compute_nodes() 的 current_running_jobs 纳入运行中的评测任务（eval_tasks）
  与已加载的推理模型（compare_tasks 持久化状态 + 内存标记兜底），
  多节点时 GPU 被评测/推理占用不再显示 0/1
- gpus() 直接按 eval_tasks / compare_tasks 派生 GPU busy/reserved 状态，
  修复 gpu_id=0 时 or -1 导致匹配失败；删除评测后 GPU 不再残留 busy
- 评测不再复用 mark_inference_loaded 内存标记，GPU 占用由任务数据驱动
- requirements.txt 补充 pytest / ruff（此前仅声明在 pyproject dev 可选依赖）

 ## 算力服务启动
 
+算力服务是一个 FastAPI 应用，同时承载 Compute API（模型训练/推理/GPU 管理）和 File Gateway（文件上传下载）路由。Docker 部署时对外暴露两个端口（19100 和 19101）均指向同一服务，方便应用平台分别配置 `api_base_url` 和 `file_gateway_url`。本地开发只需启动一个进程。
+
+### 方式一：Docker 启动（推荐）
+
 ```bash
-cd compute
-uvicorn api.main:app --reload --port 19100
+cd docker/compute
+cp .env.example .env
+docker compose up -d
 ```
 
-默认 `COMPUTE_MODE=real`。真实 GPU 接入时，在每台算力服务器上部署 Compute API、Agent、File Gateway 和 LLaMA-Factory，应用平台通过 `compute_nodes.api_base_url` 和 `compute_nodes.file_gateway_url` 主动轮询。仅在隔离联调环境可显式设置 `COMPUTE_MODE=simulator` 或 `COMPUTE_EXECUTION_MODE=simulator`。
+### 方式二：本地开发启动
+
+**Windows (cmd)：**
+
+```cmd
+cd /d E:\yg_ft\compute
+set PYTHONPATH=E:\yg_ft
+.\.venv\Scripts\python.exe -m uvicorn api.main:app --reload --port 19100
+```
+
+> `PYTHONPATH=E:\yg_ft` 是必需的，因为代码使用 `from compute.agent...` 绝对导入。
+
+**Linux / macOS：**
+
+```bash
+cd compute
+PYTHONPATH=.. uvicorn api.main:app --reload --port 19100
+```
+
+### 环境变量说明
+
+| 变量 | 默认值 | 说明 |
+|---|---|---|
+| `COMPUTE_MODE` | `real` | `real` / `simulator`，仅隔离联调用 simulator |
+| `COMPUTE_EXECUTION_MODE` | `real` | 训练执行模式 |
+| `COMPUTE_SERVICE_TOKEN` | `change_me` | 服务间认证 token |
+| `MODELTF_ROUTE_PREFIX` | `/modelTF` | API 路由前缀 |
+
+应用平台通过数据库 `compute_nodes` 表中的 `api_base_url` 和 `file_gateway_url` 主动轮询算力节点状态。

+
+平台治理涵盖用户管理、租户管理、项目管理、审批管理、审计日志、资源授权(ACL)、留存策略等企业管理能力。功能入口位于侧边栏「平台治理」和「系统设置」两个分组下。
+
+本平台核心业务是**模型微调**：用户上传数据 → 数据处理 → 模型训练 → 模型评测 → 模型推理。平台治理负责管理**谁**能访问**哪个租户/项目**的**哪些资源**。

+## 数据流转关系
+
+```
+用户登录 → 分配角色(admin/operator/viewer) + 页面权限
+    │
+    ├─ 创建租户（配额：GPU/存储/项目数）
+    │     └─ 关联用户
+    │
+    ├─ 创建项目（关联租户，选择编码ID）
+    │     ├─ 项目成员（角色：member/admin/viewer）
+    │     └─ 资源授权(ACL)：谁对什么资源有什么权限
+    │
+    ├─ 创建审批模板（定义审批流程）
+    │     └─ 审批实例：敏感操作需要审批（通过/拒绝）
+    │
+    ├─ 审计日志：所有操作自动记录（谁在什么时间做了什么）
+    │
+    └─ 留存策略：定义数据保留周期，自动清理过期数据
