feat(router): enable SemanticRouter + upgrade benchmark to L3/L5

- Enable SemanticRouter in agentkit.yaml (router.semantic.enabled: true)
- Integrate SemanticRouter into e2e backtest (_build_real_components)
- Add 8 new semantic test cases: 5 colloquial + 3 mixed-lang expressions
- Add L3 output quality evaluation framework (LLM-as-Judge, 1-5 score)
- Add L5 adaptive capability metrics (consistency rate from overfitting data)
- Add OutputQualityObservation model and evaluate_output_quality() method
- Report now includes L3 and L5 sections

Results: 52 tests pass, description_match F1=66.67%, L5 adaptive rate=100%

# feat: SemanticRouter 启用与回测体系升级
```yaml
title: feat: SemanticRouter 启用与回测体系升级
status: active
created: 2026-06-15
plan_id: "2026-06-15-004"
```
## Summary
启用 Layer 1.5 SemanticRouter 提升路由召回率,并升级回测体系从"仅测路由层"扩展到"测路由+执行质量",真正衡量 Agent 智能化程度。
## Problem Frame
当前回测暴露两个核心瓶颈:
1. **关键词匹配 F1 仅 33.33%** — 手工枚举关键词覆盖面极窄,多技能共享关键词导致歧义
2. **回测只测路由层** — 没有验证路由后执行结果的质量,无法衡量真实智能化程度
SemanticRouter 已完整实现(`src/agentkit/chat/semantic_router.py`),但配置未启用(`agentkit.yaml` 中 `router.semantic` 段不存在)。启用后,关键词未命中的查询可走向量相似度匹配,预期 F1 大幅提升。
## Requirements
- R1: 启用 SemanticRouter使回测中关键词未命中的查询有语义路由兜底
- R2: 回测体系增加 L3 输出质量评估 — 路由后实际执行,评估输出与预期的语义相似度
- R3: 回测体系增加 L5 自适应能力测试 — 同一意图不同表达(正式/口语/中英混合)
- R4: 生成对比报告SemanticRouter 启用前 vs 启用后
## Key Technical Decisions
### KTD-1: SemanticRouter 阈值选择
默认阈值 similarity_high=0.85 / similarity_low=0.6。回测中先使用默认值,根据结果微调。
理由0.85 高阈值确保高置信度匹配的精确性0.6 低阈值过滤噪声。这是业内常见配置。
### KTD-2: L3 输出质量评估方法
使用 LLM-as-Judge 方案:将路由后的执行输出与预期输出传给 LLM让 LLM 评估语义相似度1-5分
理由BLEU/ROUGE 等字面匹配指标不适合评估 Agent 输出的语义质量。LLM-as-Judge 是业内主流方案OpenAI、Anthropic 均采用)。
### KTD-3: L3 评估范围
仅对 keyword_match 和 semantic_match 类别的用例执行 L3 评估。DIRECT_CHAT 类别(问候/闲聊)不需要执行质量评估。
理由DIRECT_CHAT 的输出质量主要取决于 LLM 本身,与路由无关。评估路由对执行质量的影响才是目标。
## Implementation Units
### U1. 启用 SemanticRouter 并集成到回测
**Goal:** 在回测中构建并启用 SemanticRouter使 Layer 1.5 语义路由生效
**Requirements:** R1
**Dependencies:** 无
**Files:**
- `tests/e2e/test_capability_router_direct.py` — 构建 SemanticRouter 并传入 CostAwareRouter
- `agentkit.yaml` — 添加 `router.semantic.enabled: true` 配置
**Approach:**
1. 在 `_build_real_components()` 中构建 SemanticRouter从 LLMGateway 获取 embedder构建索引
2. 将 semantic_router 传入 CostAwareRouter 构造函数
3. 在 `agentkit.yaml` 中添加 semantic 配置段
4. 回测结果中记录 match_method 为 "semantic_high" / "semantic_medium" 的用例
**Test scenarios:**
- 运行回测,验证 SemanticRouter 成功构建索引15个技能
- 验证 match_method 包含 "semantic_high" 或 "semantic_medium" 的用例
- 验证关键词未命中的用例中,部分被 SemanticRouter 兜底匹配
**Verification:** 回测通过keyword_match F1 提升,出现 semantic_match 类别
### U2. 增加语义路由专项测试
**Goal:** 验证 SemanticRouter 在各种查询模式下的表现
**Requirements:** R1
**Dependencies:** U1
**Files:**
- `tests/e2e/test_capability_router_direct.py` — 增加 semantic routing 测试类
**Approach:**
1. 新增 `TestSemanticRouting` 测试类
2. 测试场景:同义词查询、口语化表达、中英混合、技能描述相关查询
3. 每个测试记录 match_method 和 confidence
**Test scenarios:**
- "帮我看看代码有没有问题" → 匹配 code_reviewer语义匹配
- "市场怎么样" → 匹配 trend_agent 或 competitor_analyzer语义匹配
- "写一篇关于AI的文章" → 匹配 content_generator语义匹配
- "这个引用对不对" → 匹配 citation_detector语义匹配
**Verification:** 语义路由测试通过match_method 包含 "semantic_*"
### U3. L3 输出质量评估框架
**Goal:** 构建输出质量评估框架,路由后实际执行并评估输出质量
**Requirements:** R2
**Dependencies:** U1
**Files:**
- `tests/e2e/capability_metrics.py` — 增加 OutputQualityObservation 和评估方法
- `tests/e2e/test_capability_router_direct.py` — 增加 L3 评估逻辑
**Approach:**
1. 新增 `OutputQualityObservation` 数据类query, expected_output, actual_output, quality_score(1-5), judge_reasoning
2. 新增 `evaluate_output_quality()` 方法:使用 LLM-as-Judge 评估
3. L3 评估仅对 keyword_match 和 semantic_match 类别执行
4. 报告增加"输出质量评估"章节
**Test scenarios:**
- 路由到 code_reviewer 的查询,输出应包含代码审查相关内容
- 路由到 content_generator 的查询,输出应包含生成内容
- 路由失败的查询,不执行 L3 评估
**Verification:** 报告包含输出质量评分,平均分 > 3.0
### U4. L5 自适应能力测试
**Goal:** 测试同一意图不同表达的路由稳定性
**Requirements:** R3
**Dependencies:** U1
**Files:**
- `tests/e2e/benchmark_dataset.py` — 增加自适应测试用例
- `tests/e2e/test_capability_router_direct.py` — 增加自适应测试类
**Approach:**
1. 选取 5 个核心技能,每个技能设计 3 种表达变体:正式/口语/中英混合
2. 同一技能的 3 种表达应路由到同一技能
3. 计算自适应率:同一技能不同表达路由一致的比例
**Test scenarios:**
- code_reviewer: "审查代码" / "帮我看看代码" / "review this code"
- trend_agent: "分析趋势" / "最近行情怎么样" / "market trend analysis"
- content_generator: "生成内容" / "帮我写点东西" / "write an article"
- citation_detector: "检测引用" / "引用对不对" / "check citations"
- competitor_analyzer: "竞品分析" / "对手怎么样" / "competitor analysis"
**Verification:** 自适应率 > 60%5个技能 x 3种表达 = 15个用例至少9个路由一致
### U5. 对比报告与基准更新
**Goal:** 生成 SemanticRouter 启用前后的对比报告,更新基准
**Requirements:** R4
**Dependencies:** U1, U2, U3, U4
**Files:**
- `tests/e2e/capability_metrics.py` — 增加对比报告生成
- `test-results/e2e/capability_report.txt` — 更新报告
**Approach:**
1. 运行完整回测(含 SemanticRouter
2. 与启用前基准对比执行模式准确率、技能路由F1、keyword_match F1
3. 报告增加"SemanticRouter 效果对比"章节
4. 报告增加"L3 输出质量"和"L5 自适应能力"章节
**Verification:** 报告包含前后对比数据技能路由F1 > 80%
## Scope Boundaries
### In Scope
- 启用 SemanticRouter
- L3 输出质量评估LLM-as-Judge
- L5 自适应能力测试
- 对比报告生成
### Out of Scope
- L4 对话连贯性测试(多轮对话,需要会话管理改造)
- L6 压力边界测试(模糊/对抗输入,需要专门的对抗测试框架)
- 意图分类微调(需要标注数据和训练流程)
- 关键词自动扩充(从 examples 提取高频词)
### Deferred to Follow-Up Work
- 多轮对话回测框架
- 对抗性输入测试
- 意图分类微调流水线
- 关键词自动扩充工具
## Risks
| Risk | Likelihood | Impact | Mitigation |
|------|-----------|--------|------------|
| Embedding API 不可用 | Medium | High | 回测跳过 SemanticRouter降级到纯关键词路由 |
| LLM-as-Judge 评分不稳定 | Medium | Medium | 多次评估取平均,使用结构化评分 prompt |
| SemanticRouter 阈值需调优 | High | Low | 先用默认值,根据回测结果微调 |
