+# P2C Module 1: Core Engine — 提取管线与数据模型
+
+- 日期：2026-02-22
+- 状态：Draft
+- 负责范围：提取编排、数据模型定义、质量门禁
+- 上游依赖：论文源数据（paper metadata + full text）
+- 下游消费方：Module 2（API & Storage）、Module 3（Frontend）
+
+---
+
+## 1. 模块职责
+
+Core Engine 是 P2C 的计算核心，职责是：
+
+1. 接收论文原始数据 + 用户/项目上下文，执行多阶段信息提取；
+2. 产出结构化的 `ReproContextPack`（唯一输出契约）；
+3. 对每个阶段输出执行质量校验，低质量时降级或标记人工确认；
+4. 不负责持久化、不负责 HTTP 路由、不负责 UI 渲染。
+
+**一句话定位：论文理解与执行计划的编译器。**
+
+---
+
+## 2. 与现有代码的关系
+
+本模块 **复用** 以下现有能力，不重复实现：
+
+| 现有组件 | 路径 | P2C 中的角色 |
+|---|---|---|
+| `Blueprint` dataclass | `src/paperbot/repro/models.py` | Stage B 输出类型 |
+| `EnvironmentSpec` dataclass | `src/paperbot/repro/models.py` | Stage C 输出类型 |
+| `ImplementationSpec` dataclass | `src/paperbot/repro/models.py` | Stage D 输出类型 |
+| `BlueprintDistillationNode` | `src/paperbot/repro/nodes/blueprint_node.py` | Stage B 执行节点 |
+| `EnvironmentInferenceNode` | `src/paperbot/repro/nodes/environment_node.py` | Stage C 执行节点 |
+| `AnalysisNode` | `src/paperbot/repro/nodes/analysis_node.py` | Stage D 执行节点 |
+| `PaperContext` | `src/paperbot/repro/models.py` | 输入归一化参考 |
+| `ContextEngine` | `src/paperbot/context_engine/engine.py` | 用户记忆注入 |
+
+**新增** 的部分：Stage A（文献蒸馏）、Stage E（任务拆解）、Stage F（成功标准）、编排器、证据链接器、组装器。
+
+---
+
+## 3. 核心数据模型
+

+## 6. 质量门禁
+
+### 6.1 阶段级校验
+
+每个 Stage 完成后立即校验：
+
+| 阶段 | 校验规则 | 失败策略 |
+|---|---|---|
+| A | `problem_definition` 非空 | 跳过，confidence=0 |
+| B | `architecture_type` 非 "unknown"，`module_hierarchy` 至少 1 项 | heuristic fallback |
+| C | `python_version` 合法，框架版本可解析 | 使用默认值 |
+| D | `optimizer` 非空 | 使用论文常见默认值 |
+| E | checkpoint 数量 3-12，DAG 无环 | 重试一次后降级为线性列表 |
+| F | 至少 1 项 `SuccessCriterion` | 标记 warning，不阻断 |
+
+### 6.2 Pack 级校验
+
+组装完成后：
+
+- JSON schema 校验必须通过
+- 必填字段（`paper.title`, `blueprint`, `environment`）不能为 None
+- `success_criteria` 至少 1 项（否则 warning）
+- `evidence_links` 覆盖关键字段 >= 80%（否则降低 `confidence.overall`）
+- `confidence.overall < 0.5` 时自动标记 `warnings: ["建议人工审查后再执行"]`
+
+### 6.3 离线评测集
+
+构建 50 篇带人工标注的论文集，评估维度：
+
+| 维度 | 指标 |
+|---|---|
+| 架构识别 | `architecture_type` 准确率 |
+| 超参数抽取 | precision / recall |
+| 指标目标 | target value 精确匹配率 |
+| 路线图可执行性 | 人工 1-5 分评分 |
+| 证据覆盖 | evidence link 覆盖率 |

+## 8. 与 Module 2 / Module 3 的接口契约
+
+### 对 Module 2（API & Storage）的契约
+
+Module 2 通过以下方式调用 Core Engine：
+
+```python
+# Module 2 调用 Core Engine 的唯一入口
+orchestrator = ExtractionOrchestrator(...)
+pack = await orchestrator.run(normalized_input, depth="standard", on_stage_complete=callback)
+# pack: ReproContextPack — 唯一输出
+```
+
+- `on_stage_complete` 回调用于 SSE 进度推送
+- Core Engine 不做持久化，由 Module 2 负责存储 `ReproContextPack`
+
+### 对 Module 3（Frontend）的契约
+
+Module 3 不直接调用 Core Engine，通过 Module 2 的 API 间接消费 `ReproContextPack` 的 JSON 序列化。
+
+`ReproContextPack` 的 JSON schema 即为前后端契约。
+
+---
+
+## 9. 风险与缓解
+
+| 风险 | 缓解措施 |
+|---|---|
+| Skill prompt 漂移（claude-scholar 上游更新） | 固化 snapshot 到 `p2c/skills/`，版本号管理 |
+| 抽取幻觉导致错误执行 | evidence-link 强制 + 低置信度标记人工确认 |
+| 上下文过长导致 LLM 退化 | Blueprint 压缩优先，分层注入（必要字段优先） |
+| 阶段级联失败 | 每阶段独立降级，不阻断后续阶段 |

+# P2C Module 2: API & Storage — 后端接口与持久化
+
+- 日期：2026-02-22
+- 状态：Draft
+- 负责范围：HTTP 接口、持久化层、外接 Provider Bridge
+- 上游依赖：Module 1（Core Engine）产出的 `ReproContextPack`
+- 下游消费方：Module 3（Frontend）
+
+---
+
+## 1. 模块职责
+
+1. 提供 HTTP API 供前端调用（生成、查询、创建会话）；
+2. 持久化 `ReproContextPack` 及阶段中间结果；
+3. 管理 SSE 进度推送（利用现有 `streaming.py` 能力）；
+4. 可选双写到外接 context provider（OneContext 等）；
+5. 不负责提取逻辑（由 Module 1 Core Engine 执行）。
+
+---
+
+## 2. 与现有代码的关系
+
+| 现有组件 | 路径 | 复用方式 |
+|---|---|---|
+| `APIRouter` 注册 | `src/paperbot/api/main.py` | 新增 router 注册 |
+| SSE 工具 | `src/paperbot/api/streaming.py` | 复用 `sse_response()` |
+| `SqlAlchemyResearchStore` | `src/paperbot/infrastructure/stores/research_store.py` | 扩展或新增表 |
+| `SqlAlchemyMemoryStore` | `src/paperbot/infrastructure/stores/memory_store.py` | 读取用户记忆 |
+| Alembic 迁移 | `alembic/` | 新增迁移脚本 |
+| `ContextEngine` | `src/paperbot/context_engine/engine.py` | 注入用户上下文 |

+
+## 6. 路由注册
+
+```python
+# src/paperbot/api/routes/repro_context.py
+
+from fastapi import APIRouter
+router = APIRouter(prefix="/api/research/repro/context", tags=["P2C"])
+
+@router.post("/generate")

+
+@router.delete("/{context_pack_id}")
+async def delete_context_pack(context_pack_id: str): ...
+```
+
+在 `src/paperbot/api/main.py` 中注册：
+
+```python
+from paperbot.api.routes.repro_context import router as repro_context_router
+app.include_router(repro_context_router)
+```
+
+---
+
+## 7. SSE 进度推送实现
+
+复用现有 `src/paperbot/api/streaming.py` 中的 SSE 能力。
+
+```python
+# generate endpoint 内部
+async def generate_context_pack(request: GenerateContextPackRequest):
+ async def event_generator():
+ def on_stage_complete(stage_name: str, progress: float):
+ # 通过 asyncio.Queue 传递事件
+ queue.put_nowait({
+ "event": "stage_progress",
+ "data": {"stage": stage_name, "progress": progress}
+ })
+
+ # 启动 Core Engine
+ pack = await orchestrator.run(
+ normalized_input,
+ depth=request.depth,
+ on_stage_complete=on_stage_complete,
+ )
+
+ # 持久化
+ pack_id = await bridge.save(pack, request.user_id, request.depth)
+
+ queue.put_nowait({
+ "event": "completed",
+ "data": {"context_pack_id": pack_id, "confidence": pack.confidence}
+ })
+
+ return sse_response(event_generator())
+```
+
+---
+
+## 8. 代码组织
+
+```
+src/paperbot/
+ api/routes/
+ repro_context.py # 新增：P2C API 端点
+ application/ports/
+ repro_context_port.py # 新增：Repository 接口
+ infrastructure/
+ stores/
+ repro_context_store.py # 新增：SQLAlchemy 实现
+ connectors/
+ onecontext_connector.py # 新增：OneContext provider（feature flag）
+ p2c/
+ provider_bridge.py # 新增：双写桥接
+```
+
+Alembic 迁移：
+
+```bash
+alembic revision --autogenerate -m "add repro_context_pack tables"
+alembic upgrade head
+```
+
+---
+
+## 9. 与 Module 1 / Module 3 的接口契约
+
+### 调用 Module 1（Core Engine）
+
+```python
+# 在 generate endpoint 中
+from paperbot.p2c.input_normalizer import InputNormalizer
+from paperbot.p2c.orchestrator import ExtractionOrchestrator
+
+normalizer = InputNormalizer(research_store, memory_store, context_engine)
+normalized = await normalizer.normalize(request)
+
+orchestrator = ExtractionOrchestrator(...)
+pack = await orchestrator.run(normalized, depth=request.depth, on_stage_complete=callback)
+```
+
+### 供 Module 3（Frontend）消费
+
+前端通过以下 HTTP 接口消费数据：
+
+| 前端操作 | 调用的 API | 返回数据 |
+|---|---|---|
+| 点击 "Generate Reproduction Session" | `POST /generate`（SSE） | 阶段进度 + 完成结果 |
+| 查看上下文包详情 | `GET /{pack_id}` | 完整 `ReproContextPack` JSON |
+| 列出历史包 | `GET /` | 摘要列表 |
+| 创建执行会话 | `POST /{pack_id}/session` | session_id + runbook steps |
+
+---
+
+## 10. 风险与缓解
+
+| 风险 | 缓解措施 |
+|---|---|
+| 外接 provider 不可用 | local-first，双写异步，失败仅 log |
+| `pack_json` 存储过大 | 单独表存阶段结果，主表 pack_json 为最终输出 |
+| SSE 连接中断 | 支持 `GET /{pack_id}` 轮询回退 |
+| 并发生成同一论文 | 幂等检查：同一 `(user_id, paper_id, depth)` 10 分钟内复用 |
+| 迁移兼容性 | `pack_json` 为 JSON text，schema 变更向后兼容（新增字段带默认值） |

+
+## 5. 前端状态管理
+
+### 5.1 扩展 Studio Store
+
+在 `web/src/lib/store/studio-store.ts` 中扩展：
+
+```typescript
+// 新增 state 字段
+interface StudioState {
+ // ... 现有字段 ...
+
+ // P2C 相关
+ contextPack: ReproContextPack | null;
+ contextPackLoading: boolean;

+ setContextPackLoading: (loading: boolean) => void;
+ appendGenerationProgress: (event: StageProgressEvent) => void;
+ clearGenerationProgress: () => void;
+ injectContextPackToRunbook: () => void; // pack → runbook steps 转换
+}
+```
+
+### 5.2 独立 Hook: `useContextPackGeneration`
+
+```typescript
+// web/src/hooks/useContextPackGeneration.ts
+
+export function useContextPackGeneration() {

+}
+```
+
+---
+
+## 6. UI 组件设计
+
+### 6.1 Papers Library 详情页入口按钮（复用现有）
+
+**位置**：Papers Library 论文详情页头部操作区（不新增入口按钮）。
+
+```

+**现有入口位置**：`web/src/app/papers/[id]/page.tsx`
+
+```typescript
+// web/src/app/papers/[id]/page.tsx

+```
+

+
+## 7. 页面路由与数据流
+
+### 7.1 完整用户流程
+
+```
+Papers Library Detail Page Studio Page
+┌────────────────────────┐ ┌──────────────────────────────┐
+│ 论文详情页 │ │ │
+│ │ ① click │ ContextPackPanel │
+│ [Run Reproduction] │ ──────────→ │ ┌────────────────┐ │

+ └────────────────────────┘
+```
+
+### 7.2 Studio 页面加载逻辑
+
+```typescript
+// web/src/app/studio/page.tsx (或对应路由)
+
+export default function StudioPage() {
+ const searchParams = useSearchParams();
+ const contextPackId = searchParams.get("context_pack_id");
+ const { contextPack, setContextPack } = useStudioStore();
+
+ useEffect(() => {
+ if (contextPackId && !contextPack) {
+ // 从 API 加载 context pack
+ fetch(`/api/research/repro/context/${contextPackId}`)
+ .then(res => res.json())
+ .then(setContextPack);
+ }
+ }, [contextPackId, contextPack, setContextPack]);
+
+ return (
+
+ {contextPack && (
+
+ )}
+ {/* 现有 Studio 内容 */}
+
+ );
+}
+```
+
+### 7.3 创建会话后注入 Runbook
+
+```typescript
+async function handleCreateSession() {
+ const res = await fetch(
+ `/api/research/repro/context/${contextPack.context_pack_id}/session`,
+ { method: "POST", headers: { "Content-Type": "application/json" },
+ body: JSON.stringify({ executor_preference: "auto" }) }
+ );
+ const session = await res.json();
+
+ // 注入到现有 Studio runbook
+ studioStore.setRunbookId(session.runbook_id);
+ studioStore.setRunbookSteps(session.initial_steps);
+}
+```
+
+---
+
+## 8. Next.js API Route（代理层）
+
+前端需要一个代理 route 将请求转发到 Python 后端，复用现有 proxy 模式。
+
+```
+web/src/app/api/research/repro/context/
+ route.ts # GET (list) + POST (generate)
+ [packId]/
+ route.ts # GET (detail) + DELETE
+ session/
+ route.ts # POST (create session)
+```
+
+```typescript
+// web/src/app/api/research/repro/context/route.ts
+
+const BACKEND_URL = process.env.PAPERBOT_API_URL || "http://localhost:8000";
+
+export async function POST(request: NextRequest) {
+ const body = await request.json();
+ const backendRes = await fetch(`${BACKEND_URL}/api/research/repro/context/generate`, {
+ method: "POST",
+ headers: { "Content-Type": "application/json", "Accept": "text/event-stream" },
+ body: JSON.stringify(body),
+ });
+
+ // 透传 SSE stream
+ return new Response(backendRes.body, {
+ headers: {
+ "Content-Type": "text/event-stream",
+ "Cache-Control": "no-cache",
+ "Connection": "keep-alive",
+ },
+ });
+}
+
+export async function GET(request: NextRequest) {
+ const { searchParams } = new URL(request.url);
+ const query = searchParams.toString();
+ const backendRes = await fetch(`${BACKEND_URL}/api/research/repro/context?${query}`);
+ const data = await backendRes.json();
+ return NextResponse.json(data);
+}
+```
+
+---
+
+## 9. 代码组织
+
+```

+
+## 10. 与 Module 2 的协调事项
+
+| 协调点 | 说明 |
+|---|---|
+| SSE 事件格式 | 前端假设 `event: stage_progress` / `event: completed` / `event: error`，需与后端对齐 |
+| `ReproContextPack` JSON 字段 | 前端 TypeScript 类型需与后端 Python dataclass 的 JSON 序列化一致 |
+| API 路径 | 统一使用 `/api/research/repro/context/*` 前缀 |
+| 错误响应格式 | 统一为 `{ "error": "message", "detail": "..." }` |
+| 分页参数 | `limit` + `offset`，返回 `{ items: [...], total: N }` |
+
+---
+
+## 11. 风险与缓解
+
+| 风险 | 缓解措施 |
+|---|---|
+| SSE 连接断开 | `useContextPackGeneration` 内置重连逻辑 + 轮询 fallback |
+| 大 pack JSON 导致渲染卡顿 | Tab 懒加载，仅渲染当前 tab 内容 |
+| 用户编辑 roadmap 后与后端不同步 | 编辑后的 override 通过 `create_session` 请求提交 |
+| 前后端类型漂移 | 考虑后续引入 OpenAPI spec 自动生成 TypeScript 类型 |

+# Paper-to-Context (P2C) 模块设计文档
+
+- 日期：2026-02-21
+- 状态：Draft（未提交）
+- 目标仓库：PaperBot
+- 关联方向：论文采集/收藏闭环、OneContext 上下文层、Claude Scholar skills/agents、Paper2Code 复现执行
+
+---
+
+## 1. 背景与目标
+
+你当前产品方向是：
+
+1. 每日个性化推荐论文；
+2. LLM 解释“为什么值得复现”；
+3. 用户在 PaperBot 内直接创建 task/job 去复现；
+4. 后续对接 Claude Code / Codex 执行。
+
+当前缺口不是“执行器能力”，而是**把论文转换成高质量可执行上下文**的中间层。
+P2C（Paper-to-Context）模块的职责就是：
+
+- 将论文（以及用户项目上下文）拆解为结构化复现包；
+- 在执行前完成“关键信息提取 + 任务拆解 + 约束注入”；
+- 向后兼容现有 Paper2Code 管线；
+- 为后续 Claude Code / Codex 适配层提供统一输入。
+
+一句话：**P2C 是你的“论文理解与执行计划编译器”**。
+
+---
+
+## 2. 设计原则
+
+1. **执行器无关（Executor-Agnostic）**
+ P2C 产物不绑定 CC/Codex；通过 adapter 层再转成各端会话格式。
+
+2. **结构化优先（Structured First）**
+ 先产出 JSON schema（可校验、可追踪），再渲染 Markdown（人可读）。
+
+3. **多阶段提取（Multi-pass Extraction）**
+ 不做“一次 Prompt 生成全部”；分阶段抽取与校验，失败可降级。
+
+4. **证据可追溯（Evidence Traceability）**
+ 每条关键结论必须带 evidence span/source，避免幻觉扩散。
+
+5. **本地优先 + 外接可选（Local-first + Optional External Context）**
+ 默认写入本地 memory/research store；OneContext 作为可选同步层。
+
+---
+
+## 3. 参考现状（仓库内）
+
+### 3.1 论文来源与收集（已具备）
+
+- Harvest 与检索：
+ - `src/paperbot/application/workflows/harvest_pipeline.py`
+ - `src/paperbot/application/services/paper_search_service.py`
+- Seed discovery（related/cited/citing/coauthor）：
+ - `POST /api/research/discovery/seed`（`src/paperbot/api/routes/research.py`）
+- Collections / Saved Papers / BibTeX / Zotero：
+ - `src/paperbot/api/routes/research.py`
+
+### 3.2 记忆与个性化（已具备）
+
+- `ContextEngine` + `TrackRouter`：
+ - `src/paperbot/context_engine/engine.py`
+ - `src/paperbot/context_engine/track_router.py`
+- Memory schema：
+ - `src/paperbot/memory/schema.py`
+
+### 3.3 Paper2Code 关键信息提取（已具备核心能力）
+
+- `PaperContext` / `Blueprint` / `ReproductionPlan` / `ImplementationSpec`：
+ - `src/paperbot/repro/models.py`
+- 关键提取节点：
+ - Blueprint 蒸馏（LLM + heuristic fallback）：`src/paperbot/repro/nodes/blueprint_node.py`
+ - Hyperparameter 分析（regex + LLM merge）：`src/paperbot/repro/nodes/analysis_node.py`
+ - 环境推断（year/code/LLM 三策略）：`src/paperbot/repro/nodes/environment_node.py`
+- 多代理编排与修复循环：
+ - `src/paperbot/repro/orchestrator.py`
+
+这意味着：**P2C 不需要从 0 到 1，而是把现有提取能力产品化、结构化、可复用化**。
+
+---
+
+## 4. 外部参考与可借鉴点
+
+### 4.1 OneContext（外接上下文层）
+
+可借鉴能力（以其公开 README/Documentation 为准）：
+
+- 统一 context 管理（多 session 归属同一 context）；
+- 记录 agent trajectory；
+- context 分享（链接/Slack）；
+- 共享会话导入与恢复；
+- CLI 入口与会话操作（`onecontext`/`oc`）。
+
+对 PaperBot 的价值：
+
+- 适合做“**上下文协作与共享层**”，不替代你的推荐/复现领域逻辑；
+- 可用于跨设备、跨会话续跑；
+- 可作为外接 provider 做双写。
+
+### 4.2 Claude Scholar（skills/agents 编排资产）
+
+可借鉴能力：
+
+- `agents/literature-reviewer.md`：文献检索与 Zotero 工作流规范；
+- `agents/architect.md`：架构分解模板；
+- `agents/dev-planner.md`：任务拆解与交付计划；
+- `skills/results-analysis/SKILL.md`：实验结果分析与统计报告规范；
+- `skills/planning-with-files/SKILL.md`：plan/notes/deliverable 的“文件化工作记忆”。
+
+对 PaperBot 的价值：
+
+- 可作为 P2C 各阶段的 prompt/规则资产来源；
+- 不建议直接耦合全部 command/hook 体系，建议抽取“可复用的 skill prompt 片段”。
+
+### 4.3 与现有 Paper2Code 的衔接
+
+- 你已具备论文 -> Blueprint/Spec 的 extraction 能力；
+- P2C 重点是补齐“面向产品上下文包”的 schema、质量门禁与版本化。
+
+---
+
+## 5. 模块边界与职责
+
+### 5.1 模块名称
+
+`paper_to_context`（P2C Engine）
+
+### 5.2 In Scope
+
+- 论文输入标准化（paper metadata + text + user/project memory）；
+- 多阶段提取与校验（Blueprint/Spec/Plan/Metrics）；
+- 输出标准化 `ReproContextPack`；
+- 写入本地 store，并可选同步到外接 context provider；
+- 提供 API 给 Research UI / Studio UI 调用。
+
+### 5.3 Out of Scope
+
+- 直接执行代码（由 ReproAgent/Orchestrator + executor adapter 负责）；
+- 替代推荐引擎排序；
+- 替代 OneContext 的产品 UI。
+
+---
+

+
+---
+
+## 10. API 设计（MVP）
+
+### 10.1 生成上下文包
+
+`POST /api/research/repro/context/generate`
+
+请求：
+
+```json
+{
+ "user_id": "default",
+ "project_id": "proj_001",
+ "paper_id": "paper_xxx",
+ "track_id": 30,
+ "depth": "standard",
+ "executor_preference": "auto"
+}
+```
+
+响应：
+
+```json
+{
+ "context_pack_id": "ctxp_xxx",
+ "status": "completed",
+ "summary": "...",
+ "confidence": {"overall": 0.81},
+ "next_action": "create_repro_session"
+}
+```
+
+### 10.2 获取上下文包详情
+
+`GET /api/research/repro/context/{context_pack_id}`
+
+返回完整 `ReproContextPack`。
+
+### 10.3 由上下文包创建复现会话
+
+`POST /api/research/repro/context/{context_pack_id}/session`
+
+响应：
+
+```json
+{
+ "session_id": "sess_xxx",
+ "runbook_steps": [...],
+ "initial_prompt": "..."
+}
+```
+
+> 备注：后续 CC/Codex adapter 对接时，可直接消费该接口输出。
+
+---
+
+## 11. 与现有 UI 的对接方案
+
+### 11.1 Research 页面入口
+
+在以下页面增加按钮：
+
+- discovery 卡片
+- collections item
+- saved papers item
+
+按钮：`Generate Reproduction Session`
+
+动作：
+
+1. 调 `/api/research/repro/context/generate`；
+2. 轮询或 SSE 获取阶段进度；
+3. 成功后跳转 `/studio` 并注入 context pack。
+
+### 11.2 Studio 页面注入
+
+复用 `web/src/lib/store/studio-store.ts` 的 `paperDraft` / task timeline 能力：
+
+- 将 `objective/blueprint/task_roadmap` 注入 runbook panel；
+- 在 `BlueprintPanel` 展示 extraction 产物；
+- 允许用户“编辑后再执行”（human-in-the-loop）。
+
+---
+
+## 12. 质量门禁与评估
+
+### 12.1 抽取质量门禁
+
+- JSON schema 校验必须通过；
+- 必填字段空值率 < 5%；
+- `success_criteria` 至少 1 项；
+- 关键字段证据覆盖率 >= 80%。
+
+### 12.2 离线评测集
+
+构建 50 篇带“人工标准答案”的论文集，评估：
+
+- 架构类型识别准确率；
+- 超参数抽取准确率；
+- 指标目标抽取准确率；
+- 路线图可执行率（人工评分）。
+
+### 12.3 线上业务指标
+
+- context 生成成功率
+- context -> job 创建转化率
+- job 成功率提升幅度（对比无 P2C）
+- 失败任务中“缺少关键信息”占比下降
+
+---
+
+## 13. 风险与缓解
+
+1. **技能提示词漂移（claude-scholar 上游更新）**
+ - 缓解：skill snapshot 固化到本仓库；版本号管理；差异审查。
+
+2. **外接 provider 可用性风险（OneContext）**
+ - 缓解：local-first；双写异步；失败自动回退。
+
+3. **抽取幻觉导致错误执行**
+ - 缓解：evidence-link 强制 + 低置信度人工确认。
+
+4. **上下文过长导致执行退化**
+ - 缓解：Blueprint 压缩优先；分层注入（必要字段优先）。
+
+5. **许可与合规风险（第三方 prompt 资产）**
+ - 缓解：仅引用 MIT/明确许可资产；保留归因；禁止受限内容直拷。
+
+---
+

+### Local performance baseline
+
+From `output/reports/memory_performance_baseline_10k_100k.json`:
+
+| Rows | Seed Time | Unscoped p95 | Track Scoped p95 | Batch Track p95 | Batch Paper p95 |
+|-----:|----------:|-------------:|-----------------:|----------------:|----------------:|
+| 10k | 1.04s | 39.00ms | 25.26ms | 20.46ms | 11.66ms |
+| 100k | 13.12s | 23.04ms | 56.81ms | 15.82ms | 11.73ms |
+
+Current takeaway:
+
+- Read latency is healthy for the tested local SQLite baseline.
+- The hottest path at larger scale is `track`-scoped search.
+- `batch_track` and `batch_paper` remain comparatively stable and are the best current shape for larger fan-out retrieval.
+
+## Operator Notes
+
+- ROI benchmark is manual-only and intentionally not wired into CI.
+- Run ROI benchmark with `make bench-roi` after configuring one supported LLM API key.
+- Integration branch merges the six issue branches in milestone order from `dev`.
+
+## Follow-ups
+
+- Add a scheduled or manually triggered GitHub Action for large-scale performance runs outside the default CI path.
+- Extend ROI benchmark with a runner that consumes full P2C context packs directly when that execution path is mature enough.
+- Track 1M-row memory baselines separately because they are too slow for the current local loop used in day-to-day validation.

+# MemoryBench Runtime Report — 2026-03-07
+
+## Executive Summary
+
+This report captures two live runs executed on `dev` after Epic #283 landed:
+
+1. A real `make bench-roi` run
+2. A `10k / 100k / 1M` memory performance baseline focused on the `track`-scoped path
+
+It also summarizes how memory-focused systems typically evaluate memory **effectiveness**, which is different from raw SQL or database load testing.
+
+## Branch Cleanup
+
+The temporary Epic #283 feature branches and the integration branch were deleted locally and remotely after merge.
+Only long-lived repository branches were left in place.
+
+## Live ROI Benchmark
+
+### Command
+
+```bash
+make bench-roi
+```
+
+### Artifacts
+
+- JSON report: `evals/reports/memory_roi_benchmark.json`
+- Console log: `output/reports/memory_roi_benchmark_run.log`
+
+### Result Summary
+
+| Arm | Description | Samples | First Pass Success | Avg Repair Loops | Avg Time to Pass | Token Cost |
+|-----|-------------|--------:|-------------------:|-----------------:|-----------------:|-----------:|
+| A | memory/context bridge disabled | 15 | 0.00 | 3.00 | 0.4875s | 0.0 |
+| B | seeded repro experiences enabled | 15 | 0.00 | 3.00 | 0.4883s | 0.0 |
+
+### Delta
+
+- `first_pass_success_rate`: flat
+- `repair_loops`: flat
+- `time_to_pass_sec`: +0.0008s for B, not significant
+- `token_cost_usd`: flat at `0.0`
+
+### Validity Assessment
+
+This run **did execute successfully**, but it does **not yet measure memory effectiveness well**.
+
+Dominant failure mode across all 30 samples:
+
+- `ModuleNotFoundError: No module named 'torch'`
+
+Implications:
+
+- The benchmark is currently saturated by **environment/runtime dependency failure**, not by memory quality.
+- Because both arms fail at the same external import boundary, the memory delta is washed out.
+- `token_cost_usd` stays `0.0`, which indicates the current execution path is not yet emitting usable token accounting into `LLMUsageStore` for this benchmark.
+
+### What to Fix Before Trusting ROI
+
+To make ROI meaningful, the benchmark should move from “did generated code import in a bare environment” to “did memory improve task success under a realistic execution harness”.
+
+Recommended fixes:
+
+1. Create a per-sample venv and install generated `requirements.txt` before verification.
+2. Or split verification into:
+ - syntax + local-import correctness
+ - optional dependency-aware execution
+3. Route generation through a provider path that records usage/cost consistently.
+4. Add case-level expectations where memory should help with structure reuse or debugging reuse.
+
+## 1M Memory Performance Baseline
+
+### Command
+
+```bash
+PYTHONPATH=src python scripts/benchmark_memory_performance.py \
+ --sizes 10000,100000,1000000 \
+ --query-count 10 \
+ --batch-size 20000 \
+ --output output/reports/memory_performance_track_curve_1m.json
+```
+
+### Artifacts
+
+- JSON report: `output/reports/memory_performance_track_curve_1m.json`
+- Console log: `output/reports/memory_performance_track_curve_1m.log`
+
+### Curve Summary
+
+| Rows | Seed Time | DB Size | Unscoped p95 | Track Scoped p95 | Batch Track p95 |
+|-----:|----------:|--------:|-------------:|-----------------:|----------------:|
+| 10k | 1.04s | 10.93 MB | 24.96ms | 25.86ms | 16.27ms |
+| 100k | 13.12s | 100.96 MB | 22.91ms | 55.03ms | 11.67ms |
+| 1M | 158.15s | 1004.87 MB | 24.05ms | 475.49ms | 11.58ms |
+
+### Interpretation
+
+- The general unscoped path stays roughly flat in this synthetic local baseline.
+- The **single `track`-scoped query path degrades sharply** at `1M`, rising to `475.49ms p95`.
+- The **batch track** path stays stable around `11–16ms p95`, which suggests the main issue is likely in the single-item `track` retrieval path rather than the storage layer as a whole.
+
+### Immediate Optimization Target
+
+If we want the next highest-impact optimization target, it is:
+
+- `track`-scoped single-query search at high cardinality
+
+That path should be profiled first for:
+
+- query plan / index usage
+- FTS candidate set size before scope filtering
+- sort/rerank cost after candidate selection
+- whether scope filtering happens too late in the pipeline
+
+## How Memory Projects Usually Test Effectiveness
+
+Memory-heavy systems generally do **not** stop at SQL-style pressure tests. They usually combine **task outcome**, **retrieval quality**, and **long-horizon reasoning** evaluation.
+
+### Common external patterns
+
+- **LoCoMo** evaluates long-term conversational memory with question answering over long dialogues, including single-hop, multi-hop, temporal, and open-domain questions. It is designed to measure whether an agent can use accumulated memories correctly over time.
+ - Source: https://snap-research.github.io/locomo/
+
+- **LongMemEval** focuses on longer-horizon agent memory abilities such as information extraction, question answering, temporal reasoning, multi-session reasoning, and knowledge updates.
+ - Source: https://github.com/xiaowu0162/LongMemEval
+
+- **Mem0** frames evaluation around downstream assistant quality and reports gains on benchmarks such as LoCoMo and other assistant-style tasks, emphasizing response quality lift rather than storage speed alone.
+ - Source: https://mem0.ai/research
+
+- **Letta** emphasizes memory-aware agent benchmarking with cost/performance trade-offs and task-level evaluation rather than only backend latency.
+ - Source: https://www.letta.com/blog/memory-agent-benchmark
+
+## What That Means for PaperBot
+
+A useful memory evaluation stack for PaperBot should have **two distinct layers**:
+
+### 1. Systems performance
+
+This is what SQL-style benchmarking is good at:
+
+- latency
+- throughput
+- tail latency (`p95` / `p99`)
+- storage size growth
+- write amplification / seed time
+
+### 2. Memory effectiveness
+
+This is the part that decides whether memory is actually helping the product:
+
+- retrieval relevance (`Recall@K`, `MRR`, `nDCG`)
+- context assembly correctness
+- write quality: did we store the right thing?
+- update quality: can newer memories overwrite stale ones correctly?
+- temporal reasoning: can the system answer based on *when* something happened?
+- personalization lift: does memory improve first-pass success or reduce retries?
+- abstention: does the agent avoid hallucinating when memory is missing?
+- safety: isolation, deletion compliance, prompt-injection resistance
+
+## Recommendation
+
+For the next phase, treat the current suite as:
+
+- **good on safety + retrieval + performance foundations**
+- **not yet complete on true memory usefulness measurement**
+
+The highest-value next additions would be:
+
+1. A LoCoMo / LongMemEval-style multi-session benchmark for remembered facts and temporal updates
+2. A write/update benchmark for stale-memory overwrite and contradiction resolution
+3. A fixed ROI harness with dependency-aware verification so memory lift is not hidden by missing runtime packages
+
+
+## Follow-up Update — March 7, 2026
+
+### Dependency-ready ROI smoke
+
+Artifact:
+
+- `output/reports/memory_roi_benchmark_smoke.json`
+
+What changed since the earlier ROI section in this report:
+
+- ROI now prepares a cached verification runtime from generated `requirements.txt`
+- runtime install failures are recorded with `pip` stdout/stderr and a persisted failure-log path
+- failed partial runtime caches are rebuilt automatically
+- torch-family installs prefer the CPU wheel index during verification runtime prep
+- invalid repair output such as `Unknown module` is no longer written into `requirements.txt`
+
+Current smoke result on **March 7, 2026**:
+
+- runtime preparation succeeded and reused a cached env (`req_ef8ee04c13655c4b`)
+- the dominant failure moved from missing runtime dependencies to a real code defect:
+ - `ImportError: cannot import name 'DataLoader' from 'data'`
+- `token_cost_usd` still remained `0.0` in this environment because the configured OpenAI-compatible relay returned repeated `500` overload errors for both `reasoning` and `code` routes
+
+Interpretation:
+
+- this is a meaningful improvement over the earlier invalid ROI state because the benchmark is now blocked by generated-code correctness rather than dependency bootstrap
+- a trustable LLM-backed ROI number still requires a healthy provider endpoint so the generation path can actually use `LLMService` and emit usage accounting
+
+### Multi-session effectiveness prototype
+
+Artifacts:
+
+- heuristic: `output/reports/memory_effectiveness_benchmark_heuristic.json`
+- LLM path prototype: `output/reports/memory_effectiveness_benchmark_llm.json`
+
+Implementation:
+
+- core benchmark: `src/paperbot/memory/eval/effectiveness_benchmark.py`
+- CLI: `evals/memory/bench_effectiveness.py`
+- fixture: `evals/memory/fixtures/multi_session_effectiveness.json`
+
+Current heuristic summary on **March 7, 2026**:
+
+- `question_count = 4`
+- `retrieval_hit_rate = 0.75`
+- `answer_accuracy = 1.0`
+- `temporal_accuracy = 1.0`
+- `update_accuracy = 1.0`
+- `abstention_accuracy = 1.0`
+
+What this prototype covers:
+
+- stale-memory overwrite / update quality
+- temporal state tracking across sessions
+- scope-aware retrieval
+- abstention when memory is missing
+
+That makes it a better fit for “is the memory module effective?” than pure SQL pressure testing alone.
+
+### LLM-backed ROI smoke after provider/runtime fixes
+
+Artifacts:
+
+- `output/reports/memory_roi_benchmark_smoke_openrouter.json`
+
+Additional fixes validated in this run:
+
+- OpenRouter-compatible fallback for models that reject the `system` role
+- transient `429` / `5xx` retry handling in the OpenAI-compatible provider
+- requirement normalization during verification runtime prep (`PIL -> Pillow`, dropping placeholder names such as `Unknown module`)
+- non-zero cost estimation for OpenRouter-prefixed OpenAI models such as `openai/gpt-4o-mini`
+
+Command used on **March 7, 2026**:
+
+```bash
+env -u HTTP_PROXY -u HTTPS_PROXY -u ALL_PROXY -u http_proxy -u https_proxy -u all_proxy \
+ LLM_REASONING_PROVIDER=openai \
+ LLM_REASONING_MODEL=openai/gpt-4o-mini \
+ LLM_REASONING_API_KEY_ENV=OPENROUTER_API_KEY \
+ LLM_REASONING_BASE_URL=https://openrouter.ai/api/v1 \
+ LLM_CODE_MODEL=openai/gpt-4o-mini \

+ PYTHONPATH=src python evals/memory/bench_roi.py \
+ --limit-cases 1 \
+ --runs-per-case 1 \
+ --max-repair-attempts 0 \
+ --output output/reports/memory_roi_benchmark_smoke_openrouter.json
+```
+
+Observed result:
+
+| Arm | First Pass | Repair Loops | Time to Pass | Token Cost |
+|-----|-----------:|-------------:|-------------:|-----------:|
+| A | 1.00 | 0.00 | 191.61s | $0.0078126 |
+| B | 1.00 | 0.00 | 196.15s | $0.0090378 |
+
+Interpretation:
+
+- this is the first local ROI smoke in this repo that is simultaneously **LLM-backed**, **dependency-aware**, and **cost-carrying**
+- the benchmark now measures a real reproduction outcome instead of failing at runtime bootstrap
+- for this single `transformer_seq2seq` sample, seeded memory did **not** help; it was slightly slower and slightly more expensive
+- the result is still not decision-grade because `n=1`; we need more cases and repeated runs to decide whether memory improves Paper2Code in aggregate
+- free OpenRouter models were not usable at this point in the day because the account hit the `free-models-per-day` limit, so this smoke used a low-cost paid model route instead

+# Context Engine Evaluation
+
+Offline context-engine evaluation for issue `#286` is fixture-driven and deterministic. It targets
+three behaviors already present in `ContextEngine`:
+
+- layered context assembly
+- token-guard trimming
+- advisory track routing
+
+## Files
+
+- Fixture: `evals/fixtures/context/bench_v1.json`
+- Benchmark library: `src/paperbot/context_engine/benchmark.py`
+- CLI: `scripts/eval_context_engine.py`
+- Smoke runner: `evals/runners/run_context_engine_benchmark_smoke.py`
+
+## Fixture shape
+
+Each case includes:
+
+- `query`, `query_type`, `stage`
+- routing setup: `active_track_id`, optional `track_id`
+- optional `paper_id`
+- optional `context_token_budget`
+- `expected.layers`
+- `expected.token_guard`
+- optional `expected.router_track_id`
+- deterministic store state under `state`
+
+The benchmark builds a real `ContextEngine` with fake research/memory stores and runs
+`build_context_pack()` directly, so the scorer observes the same layer assembly and token-guard
+logic that production code uses.
+
+## Metrics
+
+- `layer_precision`: expected populated layers vs actual populated layers
+- `layer_recall`: expected populated layers recovered by the engine
+- `token_guard_accuracy`: whether guard triggering matches expectation
+- `token_guard_trigger_rate`: observed guard trigger rate across cases
+- `router_coverage`: share of router-evaluable cases that produced a suggestion
+- `router_accuracy`: share of router-evaluable cases whose suggested track matched expectation
+
+## Run locally
+
+```bash
+PYTHONPATH=src python scripts/eval_context_engine.py \
+ --fixtures evals/fixtures/context/bench_v1.json \
+ --output output/reports/context_bench_v1.json \

+ --fail-under-token-guard-accuracy 1.0 \
+ --fail-under-router-coverage 1.0 \
+ --fail-under-router-accuracy 1.0
+```
+
+## Seed coverage
+
+The seed cases cover the combinations called out in the issue:
+
+- stages: `survey`, `writing`, `rebuttal`
+- query types: `short`, `long`, `track_query`, `paper_targeted`
+- one explicit token-guard overflow case
+- two router-evaluable cases with deterministic switch expectations

+# Memory Effectiveness Evaluation
+
+## Why this is different from SQL pressure testing
+
+Memory systems need two different validation layers:
+
+1. **Systems performance** — latency, throughput, storage growth, and tail latency
+2. **Task effectiveness** — whether stored memory actually improves answers, context assembly, first-pass success, and abstention quality
+
+For PaperBot, the second layer matters more when we ask questions like:
+
+- Did the memory store retrieve the right fact?
+- Did newer memories overwrite stale ones correctly?
+- Did scoped memories stay isolated?
+- Did the agent abstain when memory was insufficient?
+- Did memory reduce retries or repair loops in Paper2Code?
+
+That is why memory evaluation should not stop at SQL-style load testing.
+
+## External benchmark patterns
+
+PaperBot's effectiveness prototype follows the same broad direction used by long-horizon memory benchmarks such as:
+
+- `LoCoMo` — long-dialog memory QA with temporal and multi-hop questions
+- `LongMemEval` — multi-session memory evaluation across extraction, QA, updates, and temporal reasoning
+- `Mem0` research reporting — emphasizes downstream assistant quality, not only storage speed
+- `Letta` memory benchmark writeup — emphasizes task success, recall quality, cost, and practical agent behavior
+
+References:
+
+- https://snap-research.github.io/locomo/
+- https://github.com/xiaowu0162/LongMemEval
+- https://mem0.ai/research
+- https://www.letta.com/blog/memory-agent-benchmark
+
+## PaperBot effectiveness prototype
+
+PaperBot now includes a lightweight multi-session benchmark prototype:
+
+- Runner: `evals/memory/bench_effectiveness.py`
+- Core logic: `src/paperbot/memory/eval/effectiveness_benchmark.py`
+- Fixture: `evals/memory/fixtures/multi_session_effectiveness.json`
+
+The expanded prototype now includes **5 cases / 32 questions** and covers seven practical memory behaviors:
+
+- **Update accuracy** — the latest memory should win over stale memory
+- **Temporal accuracy** — the current state should reflect later sessions
+- **Temporal-previous accuracy** — earliest / original facts should still be recoverable
+- **Scoped retrieval** — the correct paper/track scope should be used
+- **Multi-session synthesis** — recap-style answers should combine facts across sessions
+- **Abstention accuracy** — the system should return `INSUFFICIENT_MEMORY` when evidence is missing
+- **Per-case / per-category reporting** — the report now breaks down accuracy by question type and case
+
+## Run it
+
+Heuristic runner:
+
+```bash
+PYTHONPATH=src python evals/memory/bench_effectiveness.py \
+ --top-k 4 \
+ --output output/reports/memory_effectiveness_benchmark_heuristic.json
+```
+
+LLM-backed runner:
+
+```bash
+env -u HTTP_PROXY -u HTTPS_PROXY -u ALL_PROXY -u http_proxy -u https_proxy -u all_proxy \
+LLM_REASONING_PROVIDER=openai \
+LLM_REASONING_MODEL=gpt-4o-mini \

+PYTHONPATH=src python evals/memory/bench_effectiveness.py \
+ --use-llm \
+ --top-k 4 \
+ --output output/reports/memory_effectiveness_benchmark_llm.json
+```
+
+NVIDIA Integrate endpoint example for the answering model only:
+
+```bash
+bash -ic 'cd /home/master1/PaperBot && env -u HTTP_PROXY -u HTTPS_PROXY -u ALL_PROXY -u http_proxy -u https_proxy -u all_proxy \
+ PAPERBOT_EMBEDDING_PROVIDER_CHAIN=none \

+ PYTHONPATH=src python evals/memory/bench_effectiveness.py \
+ --use-llm \
+ --top-k 4 \
+ --output output/reports/memory_effectiveness_benchmark_nvidia.json'
+```
+
+## Current results on March 7, 2026
+
+Expanded heuristic benchmark output from `output/reports/memory_effectiveness_benchmark_heuristic.json`:
+
+- `question_count = 32`
+- `retrieval_hit_rate = 1.0`
+- `answer_accuracy = 1.0`
+- `temporal_accuracy = 1.0`
+- `update_accuracy = 1.0`
+- `abstention_accuracy = 1.0`
+- `scope_accuracy = 1.0`
+- `multi_session_accuracy = 1.0`
+
+This means the benchmark fixture itself is now broad enough to cover:
+
+- longitudinal updates
+- original-vs-current temporal recall
+- paper/track scope isolation
+- recap-style multi-session synthesis
+- abstention under missing evidence
+
+LLM-backed execution is also wired up, including NVIDIA's OpenAI-compatible endpoint for reasoning. In this environment, two caveats still apply:
+
+- the answering model can hit `429 Too Many Requests` under a full 32-question run
+- NVIDIA's chat endpoint is fine for answer generation, but it is **not** an embeddings endpoint, so `PAPERBOT_EMBEDDING_PROVIDER_CHAIN=none` is required for this benchmark path
+
+A previously completed LLM-backed run on the NVIDIA route produced `retrieval_hit_rate = 1.0` but only `answer_accuracy = 0.625`, which suggests the remaining bottleneck is now the answering model / prompting path rather than retrieval itself.
+
+## How to use this with the rest of MemoryBench
+
+Use the effectiveness benchmark together with the other suites:
+
+- retrieval relevance for `Recall@K`, `MRR`, `nDCG`
+- scope isolation for zero-leak guarantees
+- injection robustness for offline detection
+- performance baselines for `10k / 100k / 1M`
+- ROI benchmarking for end-to-end Paper2Code lift
+
+A healthy memory system needs all of these together:
+
+- **fast enough**
+- **retrieves the right thing**
+- **does not leak across scopes**
+- **updates stale memory correctly**
+- **improves downstream agent behavior**

+# Memory Performance Evaluation
+
+Offline baseline harness for issue `#288`.
+
+## What it measures
+
+For each configured dataset size, the harness seeds a synthetic SQLite memory store and reports:
+
+- seed time
+- database size on disk
+- `search_memories()` unscoped latency
+- `search_memories()` track-scoped latency
+- `search_memories_batch()` track latency
+- `search_memories_batch()` paper latency
+
+Latency summaries include `avg_ms`, `p50_ms`, `p95_ms`, and `p99_ms`.
+
+## Default sizes
+
+The CLI defaults to the three baseline scales requested by the issue:
+
+- `10,000`
+- `100,000`
+- `1,000,000`
+
+## Run locally
+
+```bash
+PYTHONPATH=src python scripts/benchmark_memory_performance.py \
+ --sizes 10000,100000,1000000 \
+ --query-count 25 \
+ --output output/reports/memory_performance_baseline.json
+```
+
+For a faster smoke run during development:
+
+```bash
+PYTHONPATH=src python scripts/benchmark_memory_performance.py \
+ --sizes 1000,5000 \
+ --query-count 5
+```
+
+## Notes
+
+- The benchmark uses deterministic synthetic data and disables embedding generation so the baseline is stable and offline.
+- It is intended as a reporting baseline, not a strict CI latency gate, because runtime varies across machines.

+# P2C ROI Benchmark
+
+## Purpose
+
+This benchmark estimates the ROI of the current memory bridge on Paper2Code runs by comparing:
+
+- **Group A**: seeded repro-memory disabled
+- **Group B**: preload 10 `verified_structure` / `success_pattern` records into `ReproExperienceStore`
+
+Each arm runs the same paper set repeatedly and reports A/B deltas for:
+
+- `first_pass_success_rate`
+- `repair_loops`
+- `time_to_pass_sec`
+- `token_cost_usd`
+
+If there are at least 15 paired samples, the report also includes an approximate paired significance test.
+
+## Fixtures
+
+- Cases: `evals/memory/fixtures/roi_cases.json`
+- Seeded experiences: `evals/memory/fixtures/repro_experiences.json`
+
+The default setup uses 5 papers × 3 runs = 15 paired samples, which is enough to emit significance output.
+
+## What changed in this follow-up
+
+As of **March 7, 2026**, the manual ROI runner now does three things it did not do before:
+
+1. prepares a cached per-requirements runtime before verification
+2. surfaces dependency-install failures directly in the report metadata
+3. can route generation through the project `LLMService` path so usage/cost can be captured when the provider is healthy
+
+Key implementation points:
+
+- cached runtime prep: `src/paperbot/repro/verification_runtime.py`
+- ROI runner: `src/paperbot/memory/eval/roi_benchmark.py`
+- manual CLI: `evals/memory/bench_roi.py`
+

+
+## Useful flags
+
+- `--no-project-llm` — disable the project `LLMService` path and fall back to legacy node heuristics / SDKs
+- `--no-prepare-requirements` — skip cached dependency preparation
+- `--runtime-cache-dir` — choose where prepared runtimes are stored
+- `--verification-install-timeout` — change dependency install timeout
+- `--no-prefer-cpu-torch` — disable the CPU-only torch wheel index optimization during verification runtime prep
+
+## API key requirement
+
+The manual runner requires at least one configured provider key:
+
+- `OPENAI_API_KEY`
+- `ANTHROPIC_API_KEY`
+- `OPENROUTER_API_KEY`
+- `NVIDIA_MINIMAX_API_KEY`
+- `NVIDIA_GLM_API_KEY`
+
+Without one of these, `evals/memory/bench_roi.py` exits before starting.
+
+## Current smoke status on March 7, 2026
+
+Artifact:
+
+- `output/reports/memory_roi_benchmark_smoke.json`
+
+What is fixed:
+
+- dependency installation is now attempted in a prepared runtime instead of failing immediately on missing `torch`
+- runtime install failures now surface exact `pip` stdout/stderr and failure-log paths in the JSON report
+- failed half-built runtime caches are rebuilt automatically on the next run
+- torch-family installs prefer the CPU wheel index during verification runtime prep
+- invalid dependency repair like `Unknown module` is blocked instead of poisoning `requirements.txt`
+
+What is still blocking a trustworthy ROI number in this environment:
+
+- the local OpenAI-compatible relay returned repeated `500` overload errors for both `reasoning` and `code` routes, so `token_cost_usd` remained `0.0`
+- once dependency prep succeeded, the dominant failure moved to real generated-code quality:
+ - `ImportError: cannot import name 'DataLoader' from 'data'`
+
+That is still progress: the benchmark is now failing on an actual code-generation issue instead of an environment bootstrap issue.
+
+## Notes
+
+- Each sample uses a fresh SQLite database so the two arms do not share seeded memory.
+- The verification runtime cache is keyed by generated `requirements.txt` content hash.
+- The benchmark is still manual-only because it depends on live provider access, runtime package install, and local machine conditions.
+- If your environment injects SOCKS proxies, clear them for the benchmark command unless your provider client explicitly supports them.

+# Search Evaluation
+
+Offline retrieval evaluation for PaperBot now lives in the same `evals/` workflow as the
+existing smoke suites.
+
+## What ships in `#284`
+
+- Seed fixture: `evals/fixtures/retrieval/bench_v2.jsonl`
+- Benchmark library: `src/paperbot/application/services/retrieval_benchmark.py`
+- CLI entry: `scripts/eval_search.py`
+- CI smoke gate: `evals/runners/run_retrieval_benchmark_smoke.py`
+
+The fixture is intentionally offline and deterministic: every case includes the judged relevant
+documents plus adapter-level stub results so the benchmark exercises `PaperSearchService`
+fusion, deduplication, source weighting, and latency accounting without network access.
+
+## Fixture schema
+
+Each JSONL row represents one query case.
+
+```json
+{
+ "query_id": "q_short_rag",
+ "query": "rag",
+ "query_type": "short_acronym",
+ "source": "semantic_scholar",
+ "sources": ["semantic_scholar"],
+ "max_results": 10,
+ "judgments": [
+ {"doc_id": "id:doi:10.1000/rag-primer", "relevance": 3}
+ ],
+ "results_by_source": {
+ "semantic_scholar": [
+ {
+ "title": "RAG Primer for Practitioners",
+ "abstract": "...",
+ "year": 2025,
+ "citation_count": 120,
+ "identities": [{"source": "doi", "external_id": "10.1000/rag-primer"}]
+ }
+ ]
+ }
+}
+```
+
+### Field notes
+
+- `query_type`: powers grouped reporting such as `short_acronym`, `track_query`, `long_tail`
+- `source`: human-readable grouping label for reports
+- `sources`: actual adapter names passed into `PaperSearchService.search()`
+- `judgments.relevance`: graded relevance, expected range `0..3`
+- `results_by_source`: deterministic adapter outputs used by the offline benchmark runner
+
+## Metrics
+
+- `ndcg_at_10`: graded ranking quality for the top 10 results
+- `mrr_at_10`: first relevant hit position in the top 10
+- `recall_at_50`: fraction of judged relevant docs recovered in the top 50
+- `avg_latency_ms` / `p95_latency_ms`: per-case wall time for the offline search pipeline
+
+Reports are grouped in three views:
+
+- overall
+- by `query_type`
+- by `source`
+
+## Run locally
+
+```bash
+PYTHONPATH=src python scripts/eval_search.py \
+ --fixtures evals/fixtures/retrieval/bench_v2.jsonl \
+ --output output/reports/retrieval_bench_v2.json \
+ --fail-under-ndcg 0.95 \
+ --fail-under-mrr 0.95 \
+ --fail-under-recall 1.0
+```
+
+## CI gate
+
+CI runs `evals/runners/run_retrieval_benchmark_smoke.py`, which loads the same fixture and
+enforces the current regression guard thresholds:
+
+- `ndcg_at_10 >= 0.95`
+- `mrr_at_10 >= 0.95`
+- `recall_at_50 >= 1.0`
+
+To scale this seed set into a larger labeled collection, extend the same JSONL schema with more
+cases under `evals/fixtures/retrieval/` or move the annotations into a dedicated data directory
+once the set grows beyond smoke/regression usage.

+# MemoryBench — PaperBot Memory Module Evaluation
+
+> Epic [#283](https://github.com/your-org/PaperBot/issues/283)
+
+## 1. 为什么需要记忆评测
+
+PaperBot 的记忆模块承担着用户偏好存储、研究轨迹追踪、跨会话知识积累等核心功能。与传统 RAG 系统不同，我们的记忆系统具有**多层上下文（L0-L3）**、**多租户隔离（user × scope）**、**CRUD 生命周期**等独特特性，这些在通用 LLM benchmark 中没有覆盖。
+
+MemoryBench 的目标是：
+
+1. **量化记忆检索质量** — 使用标准 IR 指标（Recall@K、MRR、nDCG）衡量检索准确性
+2. **验证隔离正确性** — 确保多用户、多 scope 场景下零数据泄露
+3. **验证上下文组装完整性** — 确认 L0-L3 分层上下文正确构建、token 预算可控
+4. **检测注入攻击** — 防止恶意 prompt injection 污染记忆库
+5. **离线可运行** — 全部测试在 CI 中不依赖外部 API、不消耗 token
+
+---
+
+## 2. 外部基准对齐
+
+我们从四个学术/工业界记忆评测标准中提取评测维度，映射到 PaperBot 实际架构：
+
+| 外部基准 | 来源 | 我们对齐的评测维度 |
+|---|---|---|
+| **LongMemEval** | ICLR 2025 | 5 个记忆能力维度：information extraction, multi-session reasoning, knowledge update, temporal reasoning, abstention |
+| **LoCoMo** | ACL 2024 | 5 种问题类型：single-hop, multi-hop, temporal, open-domain (acronym expansion), adversarial |
+| **Mem0** | Mem0 Research | CRUD 生命周期：Add → Update → Delete → Ignore (dedup) |
+| **Letta** | Letta / MemGPT | Core/Archival memory 分层、token budget guard |
+
+### 2.1 LongMemEval 对齐 — 5 个记忆能力维度
+
+LongMemEval (ICLR 2025) 定义了长期记忆系统必须具备的五种能力。我们在 fixture 查询集中为每条 query 标注了 `memory_dimension` 字段：
+
+| 维度 | 定义 | 我们的覆盖方式 |
+|---|---|---|
+| **Information Extraction** | 从存储的记忆中精确提取事实 | 30 条 query 覆盖跨 track/paper 的事实检索 |
+| **Multi-session Reasoning** | 跨多次会话积累的信息进行推理 | 2 条 query 要求同时召回多条跨 scope 记忆 |
+| **Knowledge Update** | 记忆更新后检索到新版本而非旧版本 | 1 条检索 query + CRUD bench 的 update 测试 |
+| **Temporal Reasoning** | 对时间相关信息的排序与检索 | 3 条带有时间语义的 query（deadlines、schedules） |
+| **Abstention** | 无相关记忆时正确拒绝回答 | 4 条 adversarial query（relevant_memory_ids 为空） |
+
+### 2.2 LoCoMo 对齐 — 5 种问题类型
+
+LoCoMo (ACL 2024) 定义了对话式记忆系统的五种问题模式。我们在 fixture 中通过 `question_type` 字段标注：
+
+| 问题类型 | 定义 | 查询数 | 有效性体现 |
+|---|---|---|---|
+| **Single-hop** | 单条记忆即可回答 | 24 | 基础检索能力，目标 Recall@5 ≥ 0.90 |
+| **Multi-hop** | 需要多条记忆联合推理 | 6 | 联合召回能力，多个 relevant ID |
+| **Temporal** | 涉及时间排序/时间窗口 | 2 | 时序语义理解 |
+| **Acronym/Open-domain** | 缩写展开、术语匹配 | 4 | FTS5 词汇鲁棒性 |
+| **Adversarial** | 恶意或无答案查询 | 4 | 拒绝幻觉（abstention） |
+
+### 2.3 Mem0 对齐 — CRUD 生命周期
+
+Mem0 定义了记忆的完整 CRUD 生命周期。在 `test_scope_isolation.py` 中验证：
+
+| 操作 | 验证方式 | 通过条件 |
+|---|---|---|
+| **Create (Add)** | `add_memories()` 写入后可通过 `search_memories()` 检索到 | content 匹配 |
+| **Update** | `update_item()` 后搜索新内容能命中，搜索旧内容不再返回原 ID | old content gone |
+| **Delete** | `soft_delete_item()` 后搜索不再返回该 ID | deleted ID 不出现 |
+| **Ignore (Dedup)** | 插入完全相同 content 的记忆，应返回 `created=0, skipped=1` | 无重复写入 |
+
+### 2.4 Letta 对齐 — 分层上下文 + Token Guard
+
+Letta/MemGPT 的核心概念是 core memory（始终在上下文中）和 archival memory（按需检索）。PaperBot 将此扩展为 4 层：
+
+| 层级 | 角色 | 对应 Letta 概念 | 验证内容 |
+|---|---|---|---|
+| **L0** | 用户画像与偏好（全局 scope） | Core Memory — persona | `user_prefs` 非空 |
+| **L1** | 当前 track 进度（tasks / milestones） | Core Memory — human | `progress_state.tasks` + `milestones` 非空 |
+| **L2** | 查询相关记忆（embedding/FTS5 检索） | Archival Memory recall | `relevant_memories` 包含语义匹配记忆 |
+| **L3** | Paper 级记忆（具体论文笔记） | Archival Memory — per-document | `paper_memories` 非空（给定 paper_id 时） |
+| **Token Guard** | 总 token 不超过预算，低优先级层被截断 | Context window management | 300 token budget → actual ≤ 350 |
+

+
+## 4. Bench 详解
+
+### 4.1 Retrieval Bench v2 — 检索质量
+
+**文件**: `test_retrieval_bench.py`
+**对齐**: LongMemEval + LoCoMo
+**Issue**: [#284](https://github.com/your-org/PaperBot/issues/284)
+
+#### 测试方法论
+
+1. **Fixture 数据集构建**: 2 个模拟用户（ML/NLP 研究者 + CV/Diffusion 研究者），每人有多个 research track，共 45 条记忆覆盖 global/track/paper 三级 scope
+2. **Query 标注**: 40 条查询，每条标注了：
+ - `relevant_memory_ids`: 正确答案集合（graded relevance 0-3）
+ - `question_type`: LoCoMo 5 类
+ - `memory_dimension`: LongMemEval 5 维
+ - `difficulty`: easy / medium / hard
+3. **临时数据库**: 每次测试创建独立 SQLite 临时库，插入 fixture 数据，跑完销毁
+4. **Abstention 分离**: 4 条 adversarial 查询（无正确答案）单独计算 `abstention_accuracy`，不污染 IR 指标
+
+#### 有效性体现
+
+- **多粒度指标**: Recall@{1,3,5,10} 衡量召回覆盖，MRR@10 衡量排序质量，nDCG@10 使用分级相关性（0-3）评估排序精度
+- **分维度拆解**: 按 question_type 和 memory_dimension 分桶统计，暴露系统在特定场景下的弱点（如 multi-hop 的 recall 低于 single-hop）
+- **可复现**: 固定 fixture，无随机性，CI 可回归
+
+#### 指标与阈值
+
+| 指标 | 阈值 | 当前值 | 说明 |
+|---|---|---|---|
+| Recall@5 | ≥ 0.80 | **0.873** | top-5 召回了 87% 的相关记忆 |
+| MRR@10 | ≥ 0.65 | **0.731** | 第一个相关结果平均排在 ≈1.4 位 |
+| nDCG@10 | ≥ 0.70 | **0.747** | 加权排序质量达标 |
+| Hit@5 | — | 0.972 | 97% 的查询在 top-5 至少命中一个 |
+| Hit@10 | — | 1.000 | top-10 实现 100% 命中 |
+| Abstention | — | 0.000 | FTS5 始终返回结果（已知限制） |
+
+#### 按 question_type 拆解
+
+| 类型 | Recall@5 | MRR@10 | 分析 |
+|---|---|---|---|
+| single_hop | 0.931 | 0.770 | 最强，FTS5 精确匹配优势 |
+| multi_hop | 0.708 | 0.583 | 联合召回弱于单跳，需 embedding 增强 |
+| acronym_expansion | 0.708 | 0.875 | 排序优秀但召回有空间 |
+| temporal | 1.000 | 0.417 | 全召回但排序差，时序权重待优化 |
+
+#### 按 memory_dimension 拆解
+
+| 维度 | Recall@5 | MRR@10 | 分析 |
+|---|---|---|---|
+| information_extraction | 0.872 | 0.758 | 核心能力，达标 |
+| knowledge_update | 1.000 | 0.250 | 能召回但排序靠后 |
+| temporal_reasoning | 1.000 | 0.611 | 全召回，排序中等 |
+| multi_session_reasoning | 0.625 | 0.750 | 跨会话推理是主要改进方向 |
+
+---
+
+### 4.2 Scope Isolation + CRUD Lifecycle — 隔离与生命周期
+
+**文件**: `test_scope_isolation.py`
+**对齐**: Mem0 + LongMemEval (knowledge_update)
+**Issue**: [#285](https://github.com/your-org/PaperBot/issues/285)
+
+#### 测试方法论
+
+1. **隔离矩阵**: 2 个用户 × 3 种 scope_type (global / track / paper) × 多个 scope_id，构建 N×M 完全矩阵
+2. **三接口覆盖**: 对每种组合运行 `search_memories()`, `list_memories()`, `search_memories_batch()` 三个接口
+3. **泄露检测**: 每次查询的结果集中，检查是否出现其他用户的记忆（cross-user leak）或当前用户其他 scope 的记忆（cross-scope leak）
+4. **可见性检查**: 全局 scope 的记忆应在无 scope 限定查询中可见（required_ids 验证）
+5. **CRUD 四步**: 在隔离测试完成后，单独运行 Add → Update → Delete → Dedup 四步测试
+
+#### 有效性体现
+
+- **穷举验证**: 不是抽样测试，而是对每个用户的每种 scope 组合穷举查询
+- **零容忍**: cross-user 或 cross-scope 任何一次泄露即判定 FAIL
+- **CRUD 全链路**: 从写入到更新到删除到去重，覆盖记忆的完整生命周期
+- **三接口一致性**: 确保 search、list、batch search 三条代码路径行为一致
+
+#### 指标与阈值
+
+| 指标 | 阈值 | 当前值 | 说明 |
+|---|---|---|---|
+| cross_user_leak_rate | = 0 | **0** | 零用户间泄露 |
+| cross_scope_leak_rate | = 0 | **0** | 零 scope 间泄露 |
+| visibility_failures | = 0 | **0** | 全局记忆可见性正确 |
+| CRUD Update | pass | **PASS** | 旧内容不可检索，新内容可检索 |
+| CRUD Delete | pass | **PASS** | 软删除后搜索不返回 |
+| CRUD Dedup | pass | **PASS** | 重复插入返回 created=0, skipped=1 |
+
+---
+
+### 4.3 Context Extraction Bench — 上下文组装
+
+**文件**: `test_context_extraction.py`
+**对齐**: Letta (core/archival memory layering)
+**Issue**: [#286](https://github.com/your-org/PaperBot/issues/286)
+
+#### 测试方法论
+
+1. **数据 seeding**: 创建用户的完整研究环境 — 3 个 research track（Dense Retrieval / Diffusion Models / LLM Agents），对应的 tasks、milestones、track-scoped 记忆、paper-scoped 记忆
+2. **ContextEngine.build_context_pack()**: 调用完整的上下文构建流程，包括 TrackRouter 路由、4 层记忆加载、token guard 截断
+3. **5 个子测试**:
+ - **Layer Completeness**: 验证 L0 user_prefs、L1 tasks/milestones、L2 relevant_memories、L3 paper_memories 全部非空
+ - **Graceful Degradation**: 无 paper_id 时 L3 为空但不崩溃；不存在的用户返回空结果但不崩溃
+ - **Context Precision**: 3 组 query-to-memory 精确性验证（ColBERT MRR → 0.397; negative mining → BM25; FAISS → ANN）
+ - **Token Budget Guard**: 300 token 极低预算下总 token 不超标
+ - **TrackRouter Accuracy**: 5 组 query → track 路由正确性（keyword/embedding 四特征评分）
+
+#### 有效性体现
+
+- **端到端验证**: 不 mock 任何组件，使用真实 ContextEngine + TrackRouter + SqlAlchemyMemoryStore + SqlAlchemyResearchStore
+- **分层覆盖**: 逐层验证 L0-L3 是否完整填充，而非只看最终拼接结果
+- **降级安全**: 验证异常输入（无 paper、新用户）不会导致崩溃
+- **Embedding 离线化**: 使用 HashEmbeddingProvider（确定性哈希替代真实 embedding），CI 无需 GPU 或 API key
+
+#### 指标与阈值
+
+| 指标 | 阈值 | 当前值 | 说明 |
+|---|---|---|---|
+| Layer Completeness | 8/8 checks pass | **PASS** | L0-L3 + routing + context_layers 全部存在 |
+| Graceful Degradation | 3/3 checks pass | **PASS** | 无 paper / 空用户场景不崩溃 |
+| Context Precision | ≥ 75% | **100%** | 3/3 query 精确命中预期 fragment |
+| Token Budget Guard | ≤ 350 tokens | **215** | 300 token 预算下实际 215 token |
+| TrackRouter Accuracy | ≥ 60% | **100%** | 5/5 query 路由到正确 track |
+
+---
+
+### 4.4 Injection Robustness L1 — 注入鲁棒性
+
+**文件**: `test_injection_robustness.py`
+**Issue**: [#287](https://github.com/your-org/PaperBot/issues/287)
+
+#### 测试方法论
+
+1. **Pattern fixture**: 12 条标注样本（6 恶意 + 6 良性），覆盖常见 prompt injection 模式：
+ - `ignore previous instructions` — 指令覆盖
+ - `\nSystem:` — 标签逃逸
+ - `<|endoftext|> [INST]` — 特殊 token 注入
+ - `@assistant forget` — 角色劫持
+ - `Ｉｇｎｏｒｅ` — 全角 Unicode 绕过
+ - `Developer: new policy` — 权限提升
+2. **离线检测**: `detect_injection_patterns()` 使用正则规则集进行模式匹配，不依赖 LLM
+3. **双向评估**:
+ - **Pollution rate**: 恶意样本中未被检出的比率（越低越好）
+ - **False positive rate**: 良性样本被误报的比率（越低越好）
+
+#### 有效性体现
+
+- **对抗性样本**: 包含 Unicode 绕过、标签注入、角色劫持等高级攻击模式
+- **良性对照**: 包含讨论 injection 的正常学术文本（如"This paper studies prompt injection attacks"），验证不会误报
+- **双向指标**: 同时衡量漏检率和误报率，避免过度拦截
+
+#### 指标与阈值
+
+| 指标 | 阈值 | 当前值 | 说明 |
+|---|---|---|---|
+| Pollution Rate | ≤ 2% | **0.0%** | 6/6 恶意样本全部检出 |
+| False Positive Rate | — | **0.0%** | 6/6 良性样本零误报 |
+

+
+## 6. 已知限制与改进方向
+
+### 6.1 Abstention 准确率 = 0%
+
+FTS5 全文索引在没有精确关键词匹配时仍会返回基于 token 权重的模糊结果。这意味着对于"完全不相关"的查询，FTS5 不会返回空结果集。
+
+**改进方向**:
+- 添加 similarity score 阈值过滤（score < threshold → 返回空）
+- 在 hybrid retrieval 模式下使用 embedding cosine similarity 作为门控
+
+### 6.2 Multi-hop Recall 偏低
+
+多跳查询（需要同时召回多条记忆）的 Recall@5 为 0.708，低于 single-hop 的 0.931。这是因为 FTS5 的 BM25 排序倾向于精确匹配的单条记忆，而非语义关联的多条记忆。
+
+**改进方向**:
+- 启用 hybrid retrieval（FTS5 + embedding），利用 embedding 的语义泛化能力
+- 对 multi-hop query 做 query expansion
+
+### 6.3 Temporal 排序
+
+时序查询的 Recall@5 = 1.0 但 MRR@10 = 0.417，说明全部相关记忆都被召回，但排序靠后。
+
+**改进方向**:
+- 在排序阶段引入 recency bias
+- 对带有时间关键词的查询自动加入 created_at 排序
+
+### 6.4 Injection 样本量
+
+当前只有 12 条样本（6 恶意 + 6 良性），覆盖面有限。
+
+**改进方向**:
+- 扩充至 50+ 样本，覆盖 indirect injection、multi-language injection、base64 编码等
+- 添加 L2 层（LLM-based detection）作为 pattern matching 的兜底
+
+---
+
+## 7. 设计原则
+
+### 7.1 离线优先
+
+所有测试不依赖外部 API（OpenAI、Semantic Scholar 等）。使用：
+- **临时 SQLite 数据库**: 每次测试创建/销毁，无状态残留
+- **HashEmbeddingProvider**: 确定性哈希替代真实 embedding 模型
+- **ContextEngineConfig(offline=True)**: 禁用在线 paper 检索
+
+### 7.2 Fixture 驱动
+
+所有测试数据来自 `fixtures/` 目录下的 JSON 文件。每条查询手工标注了正确答案、相关性分级、问题类型、难度等。这确保了：
+- **可复现**: 每次运行结果一致
+- **可审计**: 评审者可直接查看 fixture 理解评测覆盖面
+- **可扩展**: 添加新用例只需编辑 JSON
+
+### 7.3 分桶诊断
+
+不只输出一个总分，而是按 question_type 和 memory_dimension 分桶统计，快速定位系统弱项。详细 per-query 结果保存在 `reports/retrieval_bench_v2.json`。
+
+### 7.4 MemoryMetricCollector 集成
+
+每个 bench 运行后通过 `MemoryMetricCollector` 将指标写入数据库，支持趋势追踪。关键指标包括：
+- `retrieval_hit_rate` (Bench 1)
+- `cross_user_leak_rate` / `cross_scope_leak_rate` (Bench 2)
+- `injection_pollution_rate` (Bench 4)

+Scope Isolation + CRUD Lifecycle Test (P0 Acceptance Criteria)
+
+Aligned with:
+ - Mem0: CRUD lifecycle (add/update/delete/ignore)
+ - LongMemEval: knowledge_update dimension
+
+Targets:
+ - cross_user_leak_rate = 0 (any leak → FAIL)
+ - cross_scope_leak_rate = 0 (any leak → FAIL)
+ - CRUD update correctness = 100%
+ - CRUD dedup correctness = 100%
+
+This test:
+1. Builds a deterministic user × scope matrix
+2. Exercises search_memories(), list_memories(), and search_memories_batch()
+3. Fails on any cross-user or cross-scope leakage
+4. Verifies same-user global memories stay visible on unscoped queries
+5. Tests CRUD lifecycle: update (old content gone), delete (not retrievable), dedup (skipped)
+6. Records cross_user_leak_rate and cross_scope_leak_rate
