- CONVERSATION_LOG.md: replace stale sandbox-lock recovery guide with P2-M2 completion record (commit a95c0db verified)
- test_rule_engine.py: rule engine unit tests (parameter registry/range recommendation/value generation)
- test_generation.py: FastAPI TestClient-based generation endpoint tests
- test_p2m2_integration.py: full 8-step integration test (project->BC->params->recommend->generate->create->download->list)

+## 2026-08-27 16:22 — P2-M2 完成：边界条件输入 + 方案编辑器（规则引擎）
+
+### 成果
+
+#### 后端：规则引擎服务
+- `web/backend/app/services/rule_engine.py`（439行）：
+  - **ScanParameter注册表**：8个可扫描参数（Airgap/Magnet_Length/Magnet_Thickness/Magnet_Arc/RMSCurrent/Shaft_Speed/Magnet_Temperature/TorquePointsPerCycle），含单位、分类、默认范围、物理上下限
+  - **BoundaryConditions解析器**：从项目JSON解析拓扑/尺寸/转速/电流/温度/目标等边界条件
+  - **recommend_range()**：基于边界条件智能推荐每个参数的扫描范围
+    - Airgap：按外径缩放（0.8%-2% D），高转矩目标偏低
+    - Magnet_Length：按外径缩放（3%-7% D），高速封顶
+    - Magnet_Thickness：按径向深度缩放
+    - RMSCurrent：以指定电流为中心（0.5x-1.5x），损耗约束封顶
+    - Shaft_Speed：以指定转速为中心（0.6x-1.4x）
+    - Magnet_Temperature：冷态到热态扫描（20-120度C）
+  - **generate_plan()**：从边界条件生成完整方案草稿（变量列表+推荐值+估算点数）
+  - **generate_values()**：生成等间距采样值（含浮点精度处理）
+
+#### 后端：方案生成API
+- `web/backend/app/routers/generation.py`（103行）：
+  - `GET /api/scan-parameters`：获取可扫描参数注册表（前端下拉用），支持按分类筛选
+  - `POST /api/recommend-range`：单参数范围推荐
+  - `POST /api/generate-plan`：从边界条件生成方案
+  - `POST /api/projects/{id}/generate-plan`：为已有项目生成方案（合并项目BC）
+- `web/backend/app/schemas/generation.py`：Pydantic Schema（ParameterInfo/RangeRecommendation/PlanGenerateRequest/Response）
+- `web/backend/app/main.py`：已注册generation路由
+
+#### 前端：边界条件输入表单
+- 改造 `ProjectList.vue` 新建项目对话框（+99行）：
+  - 结构化边界条件输入（8个字段）：外径/内径/转速/电流/磁钢温度/目标转矩/目标效率/最大损耗
+  - el-input-number数字输入，带单位后缀
+  - 两列网格布局，Boundary Conditions分区
+  - 提交时自动合并拓扑+非空BC到boundary_conditions JSON
+
+#### 前端：可视化方案编辑器
+- 重写 `ProjectDetail.vue` 新建方案对话框（+370行，900px宽）：
+  - **变量表格编辑器**：每行一个扫描变量
+    - 参数选择下拉（从scan-parameters API加载，过滤已用参数）
+    - Range模式：start/stop/step输入，自动生成values
+    - Values模式：显式输入逗号分隔值
+    - 实时显示values列表和点数
+    - 删除按钮
+  - **工具栏**：Add Variable / Generate from Rules（规则引擎一键生成）/ Clear All
+  - **实时估算**：总点数（笛卡尔积）+ 预估时间（3min/点）
+  - 创建时构建系统二兼容的plan_data格式（name/display_name/unit/values）
+
+#### 前端API层扩展
+- `generationApi`：listScanParameters / recommendRange / generatePlan / generatePlanForProject
+
+### Git提交
+- commit `a95c0db`：feat(P2-M2): boundary conditions input + visual plan editor + rule engine
+- 9个文件，+1055行，-37行
+
+### 验证结果
+1. **规则引擎单元测试**：8参数注册、范围推荐、值生成全部通过
+2. **完整集成测试（8项）**：健康检查->创建项目(带BC)->参数注册表->范围推荐->生成方案(120点)->创建方案->下载方案(系统二兼容验证)->列表 全部通过
+3. **前端构建**：vite build成功，ProjectDetail.js从6.32kB增长到13.51kB，ProjectList.js从5.47kB增长到9.18kB
+4. **系统二兼容性**：方案下载接口返回的plan_data格式与src/plan_schema.py完全一致，每个variable含name+display_name+unit+values
+
+### 规则引擎设计要点
+1. **物理缩放规则**：几何参数按外径比例缩放，符合AFM电机设计经验
+2. **中心偏移规则**：电参数以指定工况为中心，向两侧扩展
+3. **约束封顶规则**：损耗/转矩/效率目标会限制参数范围上限
+4. **拓扑过滤**：参数支持topology_supported标记，不适用拓扑自动跳过
+5. **可扩展性**：新增参数只需在SCAN_PARAMETERS字典添加条目，推荐逻辑按参数名分发
+
+### 待优化（后续里程碑）
+- generate_values浮点精度：当stop因step不整除时会额外追加，可能产生非整齐值，用户可在前端手动调整
+- 规则引擎当前基于启发式规则，P2-M3/P3可结合经验库数据做数据驱动推荐
+- 前端边界条件编辑：项目详情页目前显示原始JSON，P2-M3可改为结构化展示+编辑
+
+### P2-M2 验收标准
