比较事件、状态、长期记忆与会话摘要的一致性。**归一化策略**:对 timestamp、自动生成 id、invocation_id 等非业务字段用占位符替换(保留字段存在性,优于直接删除),剥离 temp: 临时状态,memory 结果按确定性键排序,JSON 统一 sort_keys 序列化以消除字段顺序差异。**summary 比较策略**:采用 SDK 确定性模型(覆写 `_compress_session_to_summary` 换掉 LLM,跑真实压缩流程)生成确定性摘要,再做三分比较 —— 文本走分词集合 Jaccard 语义比较(纯标准库,无 embedding 依赖),元数据(version/session_id/supersedes)严格相等,并按 session_id 匹配后专项检测 loss/overwrite/affiliation 三类故障;因 SDK 无持久 version 字段,形式化为「生成序号 + supersedes 链」可观测修订状态。**允许差异(allowed_diff)**:用 JSONPath 精确匹配 + 强制 reason,并设每 case 条数与占比上限防滥用,绝不无脑忽略。**后端接入**:轻量模式默认 InMemory vs SQLite(≤30s),Redis/MySQL 经环境变量启用,不可用时 skip,并提供 mock/sqlite 跳过策略。**创新点**:在所有公开方案的快照层注入之外,新增端到端后端数据注入(直接改 SQL 行 / Redis key 后重读),真正验证 harness 对后端数据漂移的感知能力,兑现"后端实现质量基准"的立意。发现的 SDK 不一致只在报告中列出,不在本 PR 改生产代码。 + +--- + +## 11. 创新点小结(vs 10 个 PR) +

+3. 是否**过拟合**？（train 升 val 降） +4. 改出来的 prompt**值得回写源文件**吗？（接受/拒绝 + 理由） + +### 1.2 与现有 SDK 能力的关系：编排层，不是重写 + +SDK 已提供的能力（**复用，不重写**）： + +| SDK 能力 | 位置 | 在闭环中的角色 | +|---|---|---| +|

设计共识（已收敛 → 直接沿用） + +1. **六阶段闭环骨架**一致：baseline 评测 → 失败归因 → 优化执行 → 验证集回归 → gate 决策 → 审计落盘。 +2. **失败 taxonomy 高度重合**（6–11 类，核心同名）：`format_violation` / `final_response_mismatch` / + `tool_call_error` / `parameter_error` / `knowledge_recall_insufficient` / `llm_rubric_not_met`。 +3. **过拟合检测公式收敛**：`train_delta > 0 and val_delta <= 0`。 +4. **gate 四要素一致**：val 提升阈值 + 禁止新增 hard fail + 过拟合检测 + 成本/耗时预算。 +5. **fake 只 mock 最底层**（`call_agent` / model registry），让 Evaluator / gate / report 走真实代码路径—— + 这是「无 API key 也能端到端跑通且结果可信」的关键，不 mock 高层。 +6. **report 公共字段一致**：`schema_version`、per-case delta 枚举（`new_pass/new_fail/improved/regressed/unchanged`）、 + gate decision、prompt 审计（sha256 + diff）。 +7. **三类场景构造**一致：可优化成功 / 优化无效 / 优化后退化。 + +### 2.2 关键分歧与各方案取舍 + +| 维度 | 选项（代表 PR） | 各方案问题 |

核心设计决策（本设计的取舍与创新） + +### 4.1 ★ 分层失败归因：规则快通道 + 反事实深归因 + +**问题**：归因方法在工程上分歧最大。纯规则快但浅，依赖 expected JSON 字段结构，难泛化到 +自由文本 agent；全反事实严谨但慢，每 case 多次 evaluator 调用；LLM 裁判准但依赖 API， +违背「无 key 跑通」。 + +**本设计**：两级流水线，按 case 的信号明确度自适应。 + +``` +每个失败 case + │ + ▼ +[第一层] 规则引擎（快，零成本） + 依据：EvalCaseResult 的 error_message / failed_metrics / actual-vs-expected tool 轨迹 + 输出：(category, confidence) + 规则命中且 confidence=1.0 ──→ 直接采纳，结束 + │ (规则未命中 / 多规则冲突 / 信号弱) + ▼ +[第二层] 反事实干预（慢，有预算上限，默认 4 次/case） + 方法：深拷贝该 case 的 actual_conversation，逐变量替换重评： + · 替换 final_response 为 expected → metric 修复？→ final_response_mismatch + · 替换 tool_name 为 expected → metric 修复？→ tool_selection_error + · 替换 tool_arguments 为 expected → metric 修复？→ parameter_error + · 规范化 format 重评 → metric 修复？→ format_violation + 单一修复命中 → 强归因（confidence 0.9） + 仅组合修复命中 → compound_failure（confidence 0.7） + 全未命中 → 按失败 metric 名兜底（confidence 0.5）→ 仍优于 UNKNOWN +``` + +**为什么是创新**：纯规则与全反事实的分层组合少见。全反事实把每个 case 都做多次干预（慢）；本设计只在规则 +失效时才触发反事实，多数 case 走快通道，疑难 case 才付成本。**预算上限**保证总耗时可控（验收 ≤3 分钟）。 + +**fake/trace 模式下**：反事实重评用的也是 fake judge，零 API 成本，所以两层都便宜。 +**online 模式下**：反事实有真实 judge 成本，预算上限（默认 4 次/case）保护开销。 + +**归因诚实性**：归因结果记录 `source`（rule/counterfactual/fallback） +和 `confidence`，report 里区分展示，不做「gold label 当预测」的自欺。 + +### 4.2 候选独立复评 + GEPA 提案捕获 + +**问题**：`AgentOptimizer.optimize()` 返回的 `best_pass_rate` 是优化器内部聚合分。优化器有动机高报 +（它的目标就是提升分数）。直接信它 = 让运动员当裁判。 + +**本设计**： +1. `_ProposalCapture` 订阅 GEPA 的 `on_proposal_end` 回调，**捕获每一轮候选 prompt**，包括被 GEPA 内部 + 丢弃的提案——这些往往是有教学价值的「优化后退化」样本。 +2. 按完整 prompt 内容 sha256 去重。 +3. 对每个去重候选，用 **trace-only `AgentEvaluator`** 在 train+val 上**独立重打分**，不读优化器的分。 +4. Gate 只采信自己测出来的 train/val 证据。 + +这是防「优化器自吹」的最可信做法。代价是多花一次评测，但 fake/trace 模式下零成本。 + +### 4.3 过拟合三重检测 + +issue 硬验收点：「验证集退化但训练集提升」必须拒绝。单一公式会漏。本设计三道闸，任一触发即拒绝： + +| 检测 | 公式 | 来源 | +|---|---|---| +| **显式过拟合** | `train_delta > 0 and val_delta <= 0` | 共识公式 | +| **泛化缺口** | `(train_score_delta - val_score_delta) > generalization_gap_threshold` | 抓「train 微升 val 平」的隐性感机 | +| **趋势背离** | train pass_rate 趋势升 且 val pass_rate 趋势降（多轮时） | 用 RoundRecord 序列 | + +单轮优化时前两道生效；多轮优化时三道都生效。 + +### 4.4 prompt 敏感 FakeCallAgent（改 prompt 真改行为） + +**问题**：静态 fixture 回放下，候选 prompt 改了但 call_agent 输出不变，优化是假象——验收 +「三类场景」无法真实演示。 + +**本设计**：`FakeCallAgent` 每次调用**重读** `prompts/system.md`（prompt 热加载，与 advanced_strategies +一致），解析其中的**能力标记**决定输出。baseline prompt 故意缺能力，候选 prompt 补能力 → 行为真变。 + +```python +# 伪代码：能力标记协议（写在 prompt 里，对真实 LLM 是无害的自然语言注释） +# system.md (baseline): 故意不写 JSON 输出要求 → format 失败 +# robust.md: "Always respond as strict JSON with keys {route, answer}." → format 修复 +# ineffective.md: 与 baseline 相同 → 无提升 +# overfit.md: 补了 train 需要的能力，但引入 val critical case 的错误分类 → val 退化 +``` + +**注入路径**：通过 `AgentOptimizer.optimize(call_agent=...)` 和 `AgentEvaluator.get_executer(call_agent=...)` +的公开参数注入，不 monkeypatch SDK 内部，不依赖未公开 API。 + +### 4.5 PromptSandbox 候选隔离 + +**问题**：把候选 prompt 临时写进源文件再 finally 还原——中断/并发下有还原风险，可能污染 baseline。 + +**本设计**：候选 prompt 只写进**临时目录**的 `TargetPrompt`，进出 sandbox 各做一次 read-back 校验。 +`update_source` 永远 `False`。Gate 通过后，可选的 `write_back_after_gate` 用 compare-and-swap 风格 +三重摘要校验（写前验基线未变、写后验候选落地）才回写源文件。 + +### 4.6 审计三态成本 + fail-closed + +**问题**：fake/trace 模式无真实 API 调用，成本是 0；但不能简单写 `cost=0`，否则和「online 模式真的花了 0 元」 +无法区分，审计语义混乱。 + +**本设计**：`cost_measurement` 三态： +- `unavailable`：未知（online 模式但未拿到账单）→ **fail-closed，gate 判失败** +- `measured_zero_offline`：fake/trace，确定性的 0 +- `measured_from_replay`：从 trace 的 token usage 重放估算 + +未知成本绝不误写成 0。这是审计严肃性的底线。 + +--- + +## 5. 各阶段详细设计 + +### 5.1 Baseline 评测 + +- 用 `AgentEvaluator.get_executer()` 对 train/val **分别**全量评测（不合并，便于后续按集做 delta）。 +- `num_runs=1`（fake/trace 下确定性；online 可调高平滑方差）。 +- 产出 `BaselineResult{train: SplitResult, val: SplitResult}`，每个 `SplitResult` 含 + `pass_rate / average_score / cases: list[CaseSnapshot]`。 +- `CaseSnapshot` 是 `EvalCaseResult` 的归一化投影：`eval_id / passed / score / hard_fail / + metrics[] / actual_response / expected_response / key_trajectory[]`。 + +### 5.2 失败归因 + +见 §4.1。输入 `CaseSnapshot`，输出 `FailureAttribution{category, confidence, evidence, source}`。 +每个失败 case 至少一条可解释原因（issue 验收点 4）。report 聚合 `category_counts` 与 `coverage_rate` +（被归因的失败 case / 总失败 case）。 + +### 5.3 优化执行 + +- `AgentOptimizer.optimize()` 跑 GEPA，`_ProposalCapture` 捕获候选。 +- fake 模式下：为确定性演示三类场景，`offline/candidates.py` 提供三个固定候选 prompt + （`robust/ineffective/overfit`），通过 fixture optimizer 注入；同时保留真实 GEPA 路径（online）。 +- 产出候选列表 `candidates: list[Candidate]`，每个含 `candidate_id / prompts / source(captured|fixture)`。 +- **多字段 TargetPrompt 支持**：`TargetPrompt` 支持多次 `add_path` 注册多字段。本设计默认单字段 + `system_prompt`（满足 issue「system/skill/router 一种或多种」的下限），架构上可直接扩展到 `skill` / + `router` prompt——多注册一个路径即可，归因/gate/report 全程按 `dict[str,str]` 处理，无需改逻辑。 +- **每轮候选留痕**：`_ProposalCapture` 捕获的原始每轮提案（含被 GEPA 丢弃的）连同 `OptimizeResult.rounds` + 的 `RoundRecord`（`candidate_prompts / accepted / validation_pass_rate / round_llm_cost`）原样落盘到 + `audit/rounds.json`，满足 issue「保存每轮候选 prompt」的审计要求；report 里的 `candidates` 是去重后的视图。 + +### 5.4 候选独立复评 + 逐 case delta + +- 每个候选在 PromptSandbox 内，用 trace-only `AgentEvaluator` 重测 train/val。 +- `comparator.case_delta(baseline_case, candidate_case)` 按 `eval_id` join，输出 5 桶： + `new_pass / new_fail / improved / regressed / unchanged`。 +- 这一步直接服务 issue「区分新增通过、新增失败、分数提升、分数下降」要求。 + +### 5.5 Gate 决策 + +见 §8。三态：`accept / reject / needs_review`。`needs_review` 用于「提升不够 / 证据不足」等灰色地带 +，不强行二分。每条规则记录 `passed / required / actual / expected / reason`。 + +### 5.6 审计落盘 + +每次运行落盘： +- `optimization_report.json`：主报告（schema 见 §6.4） +- `optimization_report.md`：人读版（基线表 / 归因表 / 候选决策表 / delta 表 / gate 表 / 复现命令） +- `audit/input.snapshot.json`：config + train/val/prompt 的 sha256 digest +- `audit/environment.snapshot.json`：sdk_version / git_commit / python / platform / mode / seed +- `audit/gate_decisions.json`：每候选的 gate 判定明细 +- `audit/rounds.json`：GEPA 每轮原始 `RoundRecord`（候选 prompt、accepted、分数、单轮成本），未去重 +- `audit/proposals.json`：`_ProposalCapture` 捕获的全部提案（含被 GEPA 内部丢弃的） +- 所有写盘用「写 .tmp + `os.replace`」原子写，`sort_keys=True` 保证确定性可 diff。 + +--- + +## 6. 数据结构 + +### 6.1 evalset.json（train/val 各 3 条） + +沿用 SDK `EvalCase` schema（见 [_eval_case.py:170](../../../trpc_agent_sdk/evaluation/_eval_case.py#L170)）。 +trace 模式 case 带 `eval_mode: "trace"` + `actual_conversation`。样例结构见 +advanced_strategies/data/train.evalset.json。每条 case 在 `session_input.state` 里放归因所需的 +`expected_trajectory` / `expected_format`（**仅 judge 可见，不进 prompt**，防答案泄漏）。 + +### 6.2

exact），零 API 成本。这是「归因准确率 ≥75%」 + 与「全流程 ≤3 分钟」两个看似冲突验收点的破局点：多数 case 走快通道，疑难 case 才付成本。 + +2. **过拟合三重检测**（`gate.py`）：显式公式 `train↑ 且 val↓`、泛化缺口 + `train_delta - val_delta > 阈值`（仅在 val 未达标时触发，避免误伤健康候选）、多轮趋势背离。 + 配合 critical case 回归检查，确保「val 退化但 train 提升」的候选必被拒绝。 + +3. **确定性可复现**（`offline/fixtures.py` + `reporting.py`）：fake/trace 用预录制 variant actual + + 两个无 LLM 的 SDK evaluator，全程确定性；落盘用原子写 + sha256 摘要 config/evalset/prompt， + `cost.measurement` 三态区分（unavailable / measured_zero_offline / measured_from_replay）， + 未知成本 fail-closed。 + +Gate 用可配置 AND
