+
+**Goal:** 新增 `POST /api/score` 端点，供 Dify 外部 Tool 调用，接受单条问答记录并同步返回 RAGAS 各指标得分。
+
+**Architecture:** 新增 `inline_scorer.py` 服务层封装 RAGAS 打分逻辑，以 `(judge_model, embedding_model)` 为 key 缓存 LLM 客户端；新增 `webapp/api/score.py` 路由；`ScoreRequest`/`ScoreResponse` 放入 `webapp/models.py`；`SCORE_API_TOKEN` 加入 `EvaluationSettings`。

+## Global Constraints
+
+- Python 3.12+，PEP 8，4 空格缩进，类型注解必须
+- contexts 用 `context_separator`（默认 `" |||| "`）拆分为 list[str]
+- ground_truth 为可选；缺失时跳过 context_recall / factual_correctness / semantic_similarity / noise_sensitivity

+# 异步评分记录（Async Score Jobs）Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** 新增 `POST /api/score/async` 异步端点，结果持久化至 `outputs/score-jobs/`，并在前端新增「评分记录」页面展示。
+
+**Architecture:** 新建 `ScoreJobManager`（复用 `pipeline_task_manager` 线程池模式）在后台执行 `InlineScorer.score()`，写入 JSON 文件；新增三个 REST 端点；前端新增导航页加载并轮询记录。
+
+**Tech Stack:** Python 3.12, FastAPI, Pydantic v2, threading, Vanilla JS, pytest
+
+## Global Constraints
+
+- Python 3.12+，PEP 8，4 空格缩进，类型注解必须
+- 存储路径：`outputs/score-jobs/<job_id>.json`
+- 复用现有 `ScoreRequest`（含 `effective_metrics()` 和 `contexts_as_list()` 方法）
+- 复用现有 `InlineScorer.score()` 和 `compute_weighted_score()`
+- 所有测试用 pytest，不依赖真实 LLM
+

+## 文件清单
+
+| 操作 | 文件 | 职责 |

+Add `ScoreJobs.stopAllPolls();` when switching away, in `_doSwitch` before view switching logic:
+```javascript
+    // Stop score job pollers when leaving the scorejobs view
+    if (App.activeView === "scorejobs" && view !== "scorejobs") ScoreJobs.stopAllPolls();
+```
+
+- [ ] **Step 5: Add script tag to `webapp/static/index.html`**
+
+Add before `<script src="/static/js/app.js"></script>`:

+```
+
+- [ ] **Step 6: Verify server boots**
+
+```
+python -c "from webapp.server import create_app; create_app(); print('OK')"
+```
+Expected: `OK`
+
+Also verify HTML has all new elements:
+```
+python -c "
+c = open('webapp/static/index.html', encoding='utf-8').read()
+assert 'view-scorejobs' in c
+assert 'scorejobs-container' in c

+# 优化顾问模块设计 Spec
+
+- 日期：2026-06-16
+- 状态：已确认，进入实现。
+
+## 1. 目标
+
+在现有 RAG 评测流程结束后，新增一个**优化顾问模块**（Optimization Advisor），根据本次评测的多项指标分数与低分样本，自动诊断指标偏低的原因并给出针对性的优化建议，输出为中文 Markdown 报告 + 日志摘要。
+
+对应架构设计 §11（优化策略）：将"指标到动作的映射"（§11.2）从文档形式落地为代码自动执行。
+
+---
+
+## 2. 决策摘要
+
+| 决策点 | 选择 |
+|---|---|
+| 输出形式 | `optimization_advice.md`（文件）+ 控制台/日志摘要（双输出） |
+| 生成机制 | 规则引擎定位异常指标 → LLM 结合低分样本二次解读（两层） |
+| 触发方式 | YAML 场景文件显式声明 `optimization_advisor: true`，默认关闭 |
+| LLM 实例 | 复用 `build_models()` 已创建的 `llm` 实例，不重建 client |
+| 包位置 | `rag_eval/advisor/`（独立包，对外暴露 `run_advisor()` 单一入口） |
+
+---
+
+## 3. 架构
+
+### 3.1 执行链路
+
+```
+run_scenario()
+  → load_scenario()           # 读 YAML，解析 optimization_advisor 字段
+  → build_models()            # 已有：创建 llm, embeddings
+  → build_metric_pipeline()   # 已有
+  → Evaluator.evaluate()      # 已有：打分 → EvaluationResult
+  → write_run_artifacts()     # 已有：scores.csv / summary.md / ...
+  → run_advisor(              # 新增（3 行）
+        result, scenario, llm, artifact_paths
+    )
+      → rules.diagnose(score_rows)           # 规则引擎：返回 Diagnosis 列表
+      → llm_analyzer.analyze(diags, samples) # LLM：生成中文 Markdown 建议
+      → writer.write(advice, paths)          # 写文件 + 打日志
+```
+
+### 3.2 新增文件
+
+```
+rag_eval/advisor/
+  __init__.py          ← 暴露 run_advisor()，外部唯一入口
+  rules.py             ← 纯函数规则引擎，无 LLM，可单独单测
+  llm_analyzer.py      ← 接收 llm 实例 + 诊断结构 → 中文 Markdown
+  writer.py            ← 写 optimization_advice.md，打日志摘要
+```
+
+### 3.3 修改文件（最小改动）
+
+| 文件 | 改动 |
+|---|---|
+| `rag_eval/shared/models.py` | `Scenario` 加 `optimization_advisor: bool = False` 字段 |
+| `rag_eval/config/schema.py` | `ScenarioModel` 加同名字段 + 透传到 `Scenario` |
+| `rag_eval/config/loader.py` | 透传 `optimization_advisor` 到 `Scenario` 构造 |
+| `rag_eval/reporting/artifacts.py` | `RunArtifactPaths` 加 `advice_md: Path` 字段 + `build_artifact_paths()` 加赋值 |
+| `rag_eval/execution/runner.py` | `run_scenario()` 末尾：`build_models` 返回 llm 传入，条件调用 `run_advisor()` |
+
+### 3.4 输出产物
+
+```
+outputs/online/siemens-pdf-question-bank/<run_id>/
+  scenario.snapshot.yaml
+  scores.csv
+  invalid.csv
+  summary.md
+  metadata.json
+  optimization_advice.md    ← 新增（optimization_advisor: true 时生成）
+```
+
+---
+
+## 4. 规则引擎（rules.py）
+
+### 4.1 数据结构
+
+```python
+@dataclass
+class Diagnosis:
+    metric: str           # 指标名
+    mean_score: float     # 本次均值
+    threshold: float      # 警戒阈值
+    severity: str         # "warning" | "critical"
+    root_causes: list[str]  # 可能原因（来自架构设计 §11.2）
+    suggested_actions: list[str]  # 对应可调阶段
+    low_samples: list[dict]  # 分数最低的 N 条样本（含 question/answer/ground_truth）
+```
+
+### 4.2 七条指标诊断规则
+
+阈值参考 RAG 评测最佳实践，分 warning / critical 两档：
+
+| 指标 | warning | critical | 根因方向 | 对应优化阶段（§11.2） |
+|---|---|---|---|---|
+| `faithfulness` | < 0.7 | < 0.5 | 生成未严格基于检索片段 / 幻觉 | 生成 prompt grounding、开启校验 |
+| `answer_relevancy` | < 0.7 | < 0.5 | 回答偏离问题 / 格式冗余 | 查询改写、生成 prompt 格式 |
+| `context_recall` | < 0.7 | < 0.5 | 检索遗漏关键信息 | 多查询、问题分解、Step-back、加大过召回 |
+| `context_precision` | < 0.6 | < 0.4 | 检索引入过多噪声 / 排序差 | 后检索重排、压缩、相关性过滤 |
+| `noise_sensitivity` | > 0.3 | > 0.5 | 回答被噪声片段干扰（越低越好） | 后检索相关性过滤、重排 |
+| `factual_correctness` | < 0.6 | < 0.4 | 回答事实与标准答案偏差大 | 检索与生成综合优化 |
+| `semantic_similarity` | < 0.7 | < 0.5 | 回答语义与标准答案差距大 | 生成 prompt、检索质量 |
+
+> 注：`noise_sensitivity` 越低越好（0=完全不受噪声影响），其阈值方向与其余相反。
+
+### 4.3 低分样本选取
+
+每个触发诊断的指标，取该指标分数最低的 **top-3** 样本（排除 NaN）附入 `Diagnosis.low_samples`，字段包含 `sample_id / question / answer / ground_truth / <metric_score>`。
+
+---
+
+## 5. LLM 分析器（llm_analyzer.py）
+
+### 5.1 输入
+
+- `diagnoses: list[Diagnosis]` — 规则引擎输出（仅触发阈值的指标）
+- `llm` — 已有 RAGAS LLM 实例（scenario 的 judge_model）
+- `scenario_name: str` — 用于报告标题
+
+### 5.2 Prompt 设计
+
+使用**一次 LLM 调用**，把所有触发诊断的指标和低分样本一起发送：
+
+```
+你是一个 RAG 系统优化专家，正在分析西门子医疗 CT 文档问答系统的评测结果。
+请用中文撰写一份优化建议报告，格式为 Markdown。
+
+## 评测诊断摘要
+{for each diagnosis: 指标名、均值、阈值、可能原因、建议动作}
+
+## 低分样本示例
+{for each diagnosis: top-3 低分样本的 question / answer / ground_truth}
+
+## 要求
+1. 按指标分节（## 指标名），先解释"为什么低"，再给出"具体怎么改"
+2. "具体怎么改"要结合低分样本的具体内容，而不只是泛泛建议
+3. 最后写一节 ## 优先优化次序，按性价比排序（参考：不增加调用次数的优先）
+4. 语言简洁，面向工程师，不要废话
+```
+
+### 5.3 输出
+
+LLM 返回的 Markdown 字符串，直接写入 `optimization_advice.md`（在报告头部追加运行元信息）。
+
+### 5.4 失败降级
+
+LLM 调用失败（超时/异常）时：降级为**纯规则报告**（只输出规则引擎的诊断结构，不含 LLM 解读），文件照常写出，错误信息写入报告末尾，不阻断整个评测流程。
+
+---
+
+## 6. 写出层（writer.py）
+
+### 6.1 文件写出
+
+`optimization_advice.md` 结构：
+
+```markdown
+# 优化建议报告 — <scenario_name>
+
+- run_id: `<run_id>`
+- 生成时间: `<timestamp>`
+- judge_model: `<model>`
+
+---
+
+<LLM 生成的 Markdown 正文>
+```
+
+### 6.2 日志摘要
+
+`run_advisor()` 完成后向 `logger.info` 打印一条精简摘要（单行，适合 `run_eval.bat` 结束后一眼扫到）：
+
+```
+[advisor] 触发诊断 3 项: faithfulness(0.42, critical) context_recall(0.58, warning) noise_sensitivity(0.41, critical)
+[advisor] 优化建议已写出: outputs/online/.../optimization_advice.md
+```
+
+---
+
+## 7. YAML 配置
+
+场景文件新增一个顶层字段：
+
+```yaml
+optimization_advisor: true   # 默认 false；true 时评测结束后自动生成优化建议
+```
+
+后续若需精细配置（阈值覆盖、top-N 低分样本数），可扩展为：
+
+```yaml
+optimization_advisor:
+  enabled: true
+  top_low_samples: 3          # 每个指标取几条低分样本（默认 3）
+  # thresholds:               # 可选：覆盖默认阈值
+  #   faithfulness: 0.65
+```
+
+本轮实现仅支持 `optimization_advisor: true/false`，扩展接口预留但不实现。
+
+---
+
+## 8. 测试策略
+
+| 测试 | 文件 | 说明 |
+|---|---|---|
+| 规则引擎单测 | `tests/test_advisor_rules.py` | 纯函数，无 LLM，覆盖每条规则的 warning/critical 触发、NaN 跳过、low_samples 选取 |
+| writer 单测 | `tests/test_advisor_writer.py` | mock Diagnosis 列表，验证 md 文件写出格式和日志输出 |
+| 集成（可选） | 现有 `tests/test_online_eval.py` | 验证 `optimization_advisor: true` 场景下 advice_md 存在 |
+
+LLM 分析器不写单测（依赖网络），由集成场景覆盖。
+
+---
+
+## 9. 不覆盖（本轮边界）
+
+- 不支持跨版本对比分析（只分析本次 run）
+- 不支持批量场景聚合建议
+- 不建设 Web UI 展示
+- LLM 分析器 prompt 本轮不做多语言适配（直接中文）
+- advisor 阈值本轮硬编码在 `rules.py`，不从 YAML 读取

+# 指标权重 & 文档片段权重功能设计
+
+**日期**: 2026-06-18  
+**状态**: 已批准，待实现  
+**范围**: 在「新建评估」运行评估时，支持为 RAGAS 指标和文档配置权重，计算加权综合得分并在报告中展示。
+
+---
+
+## 1. 目标
+
+1. **指标权重（Metric Weights）**：允许为每个 RAGAS 指标配置浮点权重（如 faithfulness: 0.35），计算每道题的加权综合得分 `weighted_score`。
+2. **文档权重（Doc Weights）**：允许为特定 PDF 文档名称配置权重（如 `"322_双源CT.pdf": 2.0`），该文档的题目在汇总指标均值时按权重放大贡献。
+3. **前端覆盖**：在「新建评估」页面选中场景后，展示可编辑的权重面板，运行前可临时覆盖 YAML 中的权重。
+4. **完全向后兼容**：两个字段均为可选，省略时退化为等权行为，现有场景 YAML 无需修改。
+
+---
+
+## 2. 数据模型
+
+### 2.1 场景 YAML（新增可选字段）
+
+```yaml
+# 可选。缺省时所有指标权重 = 1.0
+metric_weights:
+  faithfulness: 0.35
+  context_recall: 0.25
+  context_precision: 0.20
+  answer_relevancy: 0.20
+
+# 可选。缺省时所有文档权重 = 1.0
+doc_weights:
+  "322_双源CT成像技术.pdf": 2.0
+  "323_单源CT对比.pdf": 1.5
+```
+
+### 2.2 Pydantic Schema（`rag_eval/config/schema.py`）
+
+`ScenarioModel` 新增：
+```python
+metric_weights: dict[str, float] = Field(default_factory=dict)
+doc_weights:    dict[str, float] = Field(default_factory=dict)
+```
+
+`ConfigDict(extra="ignore")` 不变，新字段不影响既有 YAML 的加载。
+
+### 2.3 内部 Scenario dataclass（`rag_eval/shared/models.py`）
+
+`Scenario` 新增：
+```python
+metric_weights: dict[str, float] = field(default_factory=dict)
+doc_weights:    dict[str, float] = field(default_factory=dict)
+```
+
+随 `scenario.snapshot()` 序列化，供 `run_reader` / 报告层读取。
+
+---
+
+## 3. 后端：权重计算逻辑
+
+### 3.1 新模块 `rag_eval/metrics/weights.py`
+
+纯函数模块，无外部依赖，独立可测：
+
+```python
+def resolve_weight(weights: dict[str, float], key: str, default: float = 1.0) -> float:
+    """返回 key 对应的权重，缺失时返回 default。"""
+
+def compute_weighted_score(
+    scores: dict[str, float | None],
+    metric_weights: dict[str, float],
+) -> float | None:
+    """
+    给定各指标得分和权重，返回加权综合得分。
+    - 忽略 NaN / None 值
+    - metric_weights 为空时退化为等权均值
+    - 全部 NaN 时返回 None
+    公式: Σ(w_i * s_i) / Σ(w_i)，只对非 NaN 项求和
+    """
+
+def weighted_metric_means(
+    score_rows: list[dict],
+    metrics: list[str],
+    doc_weights: dict[str, float],
+) -> dict[str, float | None]:
+    """
+    对每个指标计算文档加权均值。
+    - sample_weight = doc_weights.get(row["doc_name"], 1.0)
+    - 公式: Σ(sample_weight_j * score_m_j) / Σ(sample_weight_j)
+    - doc_weights 为空时退化为普通算术均值
+    """
+```
+
+### 3.2 评估器（`rag_eval/execution/evaluator.py`）
+
+`_merge_score()` 新增两列：
+```python
+record["weighted_score"] = compute_weighted_score(
+    score.metrics, self.scenario.metric_weights
+)
+record["sample_weight"] = self.scenario.doc_weights.get(
+    sample.metadata.get("doc_name", ""), 1.0
+)
+```
+
+`scores.csv` 新增 `weighted_score`、`sample_weight` 两列。
+
+### 3.3 报告摘要（`rag_eval/reporting/summary.py`）
+
+`build_summary_markdown()` 改用 `weighted_metric_means()` 计算各指标均值；
+新增 `weighted_score` 整体均值行：
+
+```
+## Metric Means（加权）
+- faithfulness:     0.8123  (w=0.35)
+- context_recall:   0.7654  (w=0.25)
+- context_precision: 0.7200  (w=0.20)
+- answer_relevancy: 0.7400  (w=0.20)
+- **weighted_score: 0.7789**
+```
+
+---
+
+## 4. yaml_patcher 扩展（`webapp/services/yaml_patcher.py`）
+
+`apply_profiles_to_scenario()` 扩展签名，新增可选参数：
+
+```python
+def apply_profiles_to_scenario(
+    scenario_path: str,
+    judge_profile: LLMProfile | None,
+    answer_profile: LLMProfile | None,
+    dataset_profile: LLMProfile | None,
+    metric_weights: dict[str, float] | None = None,   # 新增
+    doc_weights: dict[str, float] | None = None,       # 新增
+    _resolve_absolute: bool = False,
+) -> list[str]:
+```
+
+- `metric_weights` 非 None 时写入 `data["metric_weights"]`，追加 `"metric_weights"` 到 patched 列表
+- `doc_weights` 非 None 时写入 `data["doc_weights"]`，追加 `"doc_weights"` 到 patched 列表
+
+---
+
+## 5. Webapp 模型与 API 扩展
+
+### 5.1 `webapp/models.py`
+
+`ProfileApplyRequest` 新增：
+```python
+metric_weights: dict[str, float] | None = None
+doc_weights:    dict[str, float] | None = None
+```
+
+`ProfileApplyResponse` 不变（`patched_fields` 已包含新字段名）。
+
+### 5.2 `webapp/api/llm_profiles.py` — `apply_profiles()`
+
+透传 `metric_weights` / `doc_weights` 给 `apply_profiles_to_scenario()`。
+
+---
+
+## 6. 前端：权重配置面板
+
+### 6.1 HTML（`index.html`）
+
+在 `#llm-assignment-panel` 下方新增 `#weight-config-panel`（选中场景后显示）：
+
+```
+┌─────────────────────────────────────────────┐
+│ 权重配置  （可选，留空使用场景原始配置）         │
+├─────────────────────────────────────────────┤
+│ 指标权重                                     │
+│  faithfulness        [____1.0____]           │
+│  context_recall      [____1.0____]           │
+│  ...（根据选中场景的 metrics 动态生成）         │
+│                                              │
+│ 文档权重（doc_weights）                       │
+│  [doc名称_______________] [权重__] [＋] [✕]  │
+│  [doc名称_______________] [权重__] [＋] [✕]  │
+│  ＋ 添加文档权重规则                          │
+└─────────────────────────────────────────────┘
+```
+
+### 6.2 `runner.js`
+
+- `renderScenarioItem()` 选中后调用 `Runner._renderWeightPanel(sc)` 动态生成指标行
+- `_applyProfilesIfNeeded()` 同时读取权重输入，追加到 `apply` 请求 body
+- `Runner._collectWeights()` 收集 metric_weights / doc_weights，全部为 1.0 时不发送（跳过）
+
+### 6.3 CSS（`app.css`）
+
+新增 `.weight-config-panel`、`.weight-row`、`.weight-input` 样式，与现有 `.llm-role-row` 风格一致。
+
+---
+
+## 7. 报告展示（`webapp/services/report_builder.py`）
+
+- `RunSummary.metric_means` 改用 `weighted_metric_means()` 计算（需从 `scenario.snapshot.yaml` 读取 `doc_weights` / `metric_weights`）
+- `RunSummary` 新增 `weighted_score_mean: float | None` 字段
+- 前端 `report.js` 的指标卡片区新增「综合加权得分」卡片，使用 `good/warn/bad` 配色
+
+---
+
+## 8. 测试计划
+
+| 测试文件 | 覆盖内容 |
+|----------|---------|
+| `tests/test_weights.py` | `compute_weighted_score` / `weighted_metric_means` 纯函数，含 NaN 边界、空权重、全 NaN |
+| `tests/test_dataset_build.py` | 无改动（隔离良好） |
+| `tests/test_offline_eval.py` | `_merge_score` 新增 weighted_score / sample_weight 列断言 |
+| `tests/webapp/test_llm_profiles_api.py` | `apply_profiles` 带 metric_weights / doc_weights 的 patching 测试 |
+
+---
+
+## 9. 改动文件清单
+
+| 文件 | 改动类型 |
+|------|---------|
+| `rag_eval/config/schema.py` | 新增字段 |
+| `rag_eval/shared/models.py` | 新增字段 |
+| `rag_eval/config/loader.py` | 透传新字段到 Scenario |
+| `rag_eval/metrics/weights.py` | **新建** |
+| `rag_eval/execution/evaluator.py` | `_merge_score` 新增两列 |
+| `rag_eval/reporting/summary.py` | 改用加权均值 |
+| `webapp/services/yaml_patcher.py` | 新增 metric_weights / doc_weights 参数 |
+| `webapp/models.py` | ProfileApplyRequest 新增字段；RunSummary 新增 weighted_score_mean |
+| `webapp/api/llm_profiles.py` | 透传新参数 |
+| `webapp/services/report_builder.py` | 加权均值计算 |
+| `webapp/static/index.html` | 新增权重配置面板 |
+| `webapp/static/js/runner.js` | 权重面板逻辑 |
+| `webapp/static/css/app.css` | 新增权重面板样式 |
+| `tests/test_weights.py` | **新建** |
+
+---
+
+## 10. 向后兼容保证
+
+- `metric_weights: {}` + `doc_weights: {}` → 所有权重 = 1.0，行为与当前完全一致
+- 现有场景 YAML 不含这两个字段 → Pydantic `default_factory=dict` 填充空字典
+- `scores.csv` 新增两列不影响现有报告读取（`run_reader` 只读已知列）

+| `ground_truth` | str | ❌ | 标准答案；缺失时跳过依赖它的指标（context_recall、factual_correctness、semantic_similarity） |
+| `context_separator` | str | ❌ | 默认 `" \|\|\|\| "`（四个竖线，两侧各一空格） |
+| `metrics` | list[str] | ❌ | 默认 `["faithfulness", "answer_relevancy", "context_recall", "context_precision"]` |
+| `judge_model` | str | ❌ | 默认读 `.env` 中 `RAGAS_JUDGE_MODEL` |
+| `embedding_model` | str | ❌ | 默认读 `.env` 中 `RAGAS_EMBEDDING_MODEL` |
+
+**响应体（200 OK）：**
+
+```json
+{
+  "scores": {
+    "faithfulness":     0.8750,
+    "answer_relevancy": 0.9200
+  },
+  "weighted_score": 0.8975,
+  "latency_ms": 3420
+}
+```
+
+**错误响应：**
+
+| 状态码 | 场景 |
+|--------|------|
+| 400 | 必填字段缺失、metrics 名称不合法 |
+| 401 | 配置了 `SCORE_API_TOKEN` 但请求未携带有效 Bearer Token |
+| 422 | 请求体 JSON 格式错误（Pydantic 校验） |
+| 500 | RAGAS 内部评分异常，附带 error 字段 |
+
+**鉴权（可选）：**  
+若 `.env` 中 `SCORE_API_TOKEN` 非空，则要求请求头携带 `Authorization: Bearer <token>`。为空则不鉴权（内网部署场景）。
+
+---
+
+## 3. 架构与文件改动
+
+### 新文件
+
+| 文件 | 职责 |
+|------|------|
+| `webapp/api/score.py` | 路由定义，请求验证，调用 InlineScorer |
+| `webapp/services/inline_scorer.py` | LLM 客户端缓存 + RAGAS 评分逻辑封装 |
+
+### 修改文件
+
+| 文件 | 改动 |
+|------|------|
+| `webapp/models.py` | 新增 `ScoreRequest`、`ScoreResponse` |
+| `webapp/server.py` | 注册 `score.router`，更新 `openapi_tags` |
+| `rag_eval/settings.py` | 新增 `score_api_token: str | None` 字段 |
+
+---
+
+## 4. `inline_scorer.py` 设计
+
+```python
+class InlineScorer:
+    """同步执行 RAGAS 单题评分，内部缓存 LLM 客户端。"""
+
+    def score(
+        self,
+        question: str,
+        answer: str,
+        contexts: list[str],
+        ground_truth: str | None,
+        metrics: list[str],
+        judge_model: str,
+        embedding_model: str,
+        settings: EvaluationSettings,
+    ) -> dict[str, float | None]:
+        """返回 {metric_name: score} 字典，NaN 记为 None。"""
+```
+
+**客户端缓存策略：**  
+以 `(judge_model, embedding_model)` 为 key，缓存 `(llm, embeddings)` 对象，避免每次请求都重建 AsyncOpenAI 连接。缓存为模块级单例（`_scorer_cache: dict`），线程安全（加 `threading.Lock`）。
+
+**评分执行：**  
+复用 `build_metric_pipeline` 构建 `MetricPipeline`，然后 `asyncio.run(pipeline.score_sample(sample))` 执行。与现有 `evaluator.py` 模式一致。
+
+**ground_truth 为空时的指标跳过逻辑：**  
+`context_recall`、`factual_correctness`、`semantic_similarity`、`noise_sensitivity` 需要 ground_truth；若请求中未提供，自动从 metrics 列表中移除这些指标，并在响应中对应字段返回 `null`。
+
+---
+
+## 5. Dify 侧配置方法
+
+1. 在 Dify 「工具」→「自定义工具」中创建新工具
+2. 填写 OpenAPI Schema（与 `/api/score` 端点对齐）
+3. 鉴权方式：API Key（Bearer）或无鉴权
+4. 在 Agent / Workflow 节点中引用该工具，将 `question`、`answer`、`contexts` 变量映射到工具输入
+
+---
+
+## 6. 不在范围内
+
+- 批量评分接口（异步 job）
+- Dify Workflow 节点插件（需要 Dify 插件开发框架）
+- 评分结果持久化到 scores.csv
+- 与现有 report_builder 集成展示

+# Linux 一键部署脚本设计
+
+**日期**: 2026-06-22  
+**状态**: 已批准，待实现  
+**范围**: 为 siemens_ragas 项目提供 Linux 环境的部署与运维脚本（无 Docker，无 systemd）。
+
+---
+
+## 1. 目标
+
+提供四个 Bash 脚本，覆盖 Linux 服务器上的完整生命周期：
+
+| 脚本 | 职责 |
+|------|------|
+| `deploy.sh` | 一键完成环境检查、依赖安装、配置初始化、启动服务 |
+| `start.sh` | 仅启动 Web 服务（已部署后复用，不重装依赖） |
+| `stop.sh` | 停止后台 Web 服务 |
+| `run_eval.sh` | 运行单次评估（对应 Windows 的 `run_eval.ps1`） |
+
+---
+
+## 2. 约束与假设
+
+- Linux 目标环境有 PyPI 网络访问（pip 可直接安装）
+- 代码已通过 `git clone` 或文件拷贝到服务器
+- 使用 `pip + venv`（不使用 uv）
+- Web 服务监听 `0.0.0.0:8800`（内网可达）
+- 后台运行使用 `nohup`，PID 写入 `.server.pid`，日志追加到 `logs/server.log`
+- 所有脚本均放在仓库根目录，路径相对于 `$SCRIPT_DIR`
+
+---
+
+## 3. `deploy.sh` 详细设计
+
+### 3.1 阶段 1：Python 版本检查
+
+```
+require Python >= 3.12
+```
+
+- `python3 --version` 解析 major.minor
+- 不满足则打印错误并 `exit 1`
+- 满足则打印 `[OK] Python X.Y.Z`
+
+### 3.2 阶段 2：虚拟环境
+
+- 目标路径：`$SCRIPT_DIR/.venv`
+- 已存在则跳过创建（打印 `[OK] .venv already exists`）
+- 不存在则 `python3 -m venv .venv`
+
+### 3.3 阶段 3：依赖安装
+
+```bash
+.venv/bin/pip install --upgrade pip -q
+.venv/bin/pip install -e . -q          # 安装 pyproject.toml 中的依赖
+.venv/bin/pip install fastapi uvicorn httpx -q  # Web 服务额外依赖
+```
+
+- 失败则打印错误并 `exit 1`
+- `fastapi`、`uvicorn`、`httpx` 在 `pyproject.toml` 中未列，需单独安装
+
+### 3.4 阶段 4：配置文件
+
+- 若 `.env` 不存在：`cp .env.example .env`，打印警告提示用户编辑后再启动
+- 若 `.env` 已存在：跳过，打印 `[OK] .env found`
+
+### 3.5 阶段 5：目录初始化
+
+创建以下目录（`mkdir -p`，幂等）：
+- `configs/` — LLM Profile 持久化存储
+- `logs/` — 评估日志 + 服务器日志
+- `outputs/` — 评估运行产物
+- `datasets/` — 原始数据集
+
+### 3.6 阶段 6：Demo 数据
+
+- 检查 `outputs/kba-knowledge-base-offline-baseline/` 是否存在
+- 不存在则运行 `.venv/bin/python scripts/seed_sample_run.py`
+- 失败时打印 `[WARN]`（非致命，报告页为空但服务可启动）
+
+### 3.7 阶段 7：端口检测
+
+- 默认端口 `8800`
+- 用 `ss -tlnp` 或 `netstat -tlnp` 检查是否占用
+- 占用则尝试 `8801`，仍占用则报错退出
+
+### 3.8 阶段 8：启动服务
+
+```bash
+nohup .venv/bin/python webmain.py \
+    --host 0.0.0.0 \
+    --port $PORT \
+    >> logs/server.log 2>&1 &
+echo $! > .server.pid
+```
+
+- 等待 2 秒后用 `kill -0 $PID` 检测进程是否存活
+- 存活则打印 URL 和 stop 方法
+- 未存活则打印 `[ERROR] Server failed to start. Check logs/server.log.` 并 `exit 1`
+
+---
+
+## 4. `start.sh` 详细设计
+
+单独负责启动，不做任何环境初始化。
+
+```bash
+#!/usr/bin/env bash
+# 检查 .venv 存在
+# 端口检测（同 deploy.sh 逻辑）
+# 检查 .env 存在（不存在则 warn 但不阻止）
+# nohup 启动 + PID 文件 + 存活验证
+# 打印 URL
+```
+
+---
+
+## 5. `stop.sh` 详细设计
+
+```bash
+#!/usr/bin/env bash
+# 读取 .server.pid
+# 若文件不存在：打印 "No server PID file found." 退出
+# kill $PID
+# 等待 2 秒，若进程仍存活用 kill -9
+# 删除 .server.pid
+# 打印 "Server stopped."
+```
+
+---
+
+## 6. `run_eval.sh` 详细设计
+
+对应 Windows 的 `run_eval.ps1`。
+
+```
+用法:
+  ./run_eval.sh                          # online eval (默认)
+  ./run_eval.sh offline                  # offline smoke
+  ./run_eval.sh scenarios/xxx.yaml       # 自定义场景
+  ./run_eval.sh online DEBUG             # 自定义日志级别
+```
+
+- 参数 1（Scenario）：`online` / `offline` / 文件路径，默认 `online`
+- 参数 2（LogLevel）：`DEBUG` / `INFO` / `WARNING` / `ERROR`，默认 `INFO`
+- 场景别名映射：
+  - `online` → `scenarios/online/siemens-pdf-question-bank-online.yaml`
+  - `offline` → `scenarios/offline/siemens-pdf-offline-smoke.yaml`
+- 时间戳日志文件：`logs/eval_$(date +%Y-%m-%d_%H%M%S).log`
+- 环境变量：`PYTHONIOENCODING=utf-8 PYTHONPATH=.`
+- 调用：`.venv/bin/python main.py --scenario $SCENARIO --log-file $LOG_FILE --log-level $LOG_LEVEL`
+- 非零退出码时打印错误并 `exit 1`
+
+---
+
+## 7. 通用约定
+
+- 所有脚本首行：`#!/usr/bin/env bash`
+- `set -euo pipefail` — 错误立即退出，未定义变量报错，管道错误传播
+- `SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"` — 从任意目录执行均正确
+- `cd "$SCRIPT_DIR"` — 切换到仓库根目录
+- 颜色输出：绿色 `[OK]`、黄色 `[WARN]`、红色 `[ERROR]`（检测 tty，非交互式终端降级为无色）
+- 执行权限：脚本自身需要 `chmod +x`（在 deploy.sh 内对其他脚本自动 chmod）
+
+---
+
+## 8. 不在范围内
+
+- Docker / docker-compose 支持
+- systemd service 配置
+- Nginx 反向代理配置
+- SSL/TLS 配置
+- 离线/内网镜像源配置

+# 异步评分记录功能设计
+
+**日期**: 2026-06-24  
+**状态**: 已批准，待实现  
+**范围**: 新增 `POST /api/score/async` 异步评分端点，评分结果持久化到磁盘，前端新增「评分记录」页面展示。
+
+---
+
+## 1. 目标
+
+- Dify 工作流调用 `/api/score/async` 立即返回 `job_id`（202），不等待评分完成
+- 后台异步执行 RAGAS 评分，结果写入 `outputs/score-jobs/<job_id>.json`
+- RAGAS 平台新增「评分记录」导航页，列表展示所有评分记录及状态
+
+---
+
+## 2. 架构
+
+```
+Dify → POST /api/score/async → 202 {job_id, status:"queued"}
+                                      ↓
+                              ScoreJobManager (线程池)
+                                      ↓
+                              InlineScorer.score()
+                                      ↓
+                        outputs/score-jobs/<job_id>.json
+                                      ↓
+              GET /api/score/jobs ← 前端「评分记录」页轮询
+```
+
+---
+
+## 3. 存储格式
+
+`outputs/score-jobs/<job_id>.json`:
+
+```json
+{
+  "job_id": "abc123def456",
+  "status": "completed",
+  "created_at": "2026-06-24T09:00:00+00:00",
+  "finished_at": "2026-06-24T09:00:15+00:00",
+  "request": {
+    "question": "双源CT的时间分辨率是多少?",
+    "answer": "双源CT的单扇区时间分辨率为75ms。",
+    "contexts": null,
+    "ground_truth": null,
+    "metrics": ["answer_relevancy"],
+    "judge_model": "gpt-5",
+    "embedding_model": "text-embedding-3-small"
+  },
+  "scores": {"answer_relevancy": 0.9075},
+  "weighted_score": 0.9075,
+  "latency_ms": 12500,
+  "skipped_metrics": [],
+  "error": null
+}
+```
+
+---
+
+## 4. API 端点
+
+### `POST /api/score/async`
+
+请求体与 `POST /api/score` 完全相同（`ScoreRequest`）。
+
+```json
+// 立即返回 202
+{"job_id": "abc123def456", "status": "queued"}
+```
+
+### `GET /api/score/jobs`
+
+返回所有评分记录，按创建时间倒序：
+```json
+{"jobs": [{...ScoreJobStatus...}]}
+```
+
+### `GET /api/score/jobs/{job_id}`
+
+返回单条评分记录详情。
+
+---
+
+## 5. 新增文件
+
+| 文件 | 职责 |
+|------|------|
+| `webapp/services/score_job_manager.py` | ScoreJobManager：线程池 + JSON 持久化 |
+| `webapp/api/score_jobs.py` | 3 个端点路由 |
+| `webapp/static/js/score_jobs.js` | 前端列表逻辑 + 轮询 |
+
+## 6. 修改文件
+
+| 文件 | 改动 |
+|------|------|
+| `webapp/models.py` | 新增 `AsyncScoreJobStatus`、`AsyncScoreJobResponse` |
+| `webapp/server.py` | 注册 score_jobs router，更新 OPENAPI_TAGS |
+| `webapp/static/index.html` | 新增导航项 + section |
+
+---
+
+## 7. 前端「评分记录」页
+
+列表列：时间 / 问题摘要（前40字）/ 指标 / 得分 / 状态
+
+- 进入页面自动刷新
+- `queued/running` 记录每 5 秒轮询 `GET /api/score/jobs/{id}` 更新状态
+- 得分按 scoreClass（good/warn/bad）着色
+
+---
+
+## 8. Dify 改造
+
+只改 HTTP 节点 URL：`/api/score` → `/api/score/async`，删除解析响应的代码节点。
