+# geMoldInsight 演进路线图
+
+> 本文档是代码与功能演进的执行清单，基于 2026-07-13 的全量代码体检。每项含「现象 / 证据 / 修法 / 验证」，按 P0→P3 推进，完成后勾选。
+
+## 诊断
+
+代码已演进到「双应用模块化」形态（`entrypoints/` + `moldinsight/` + `inventory/` + `shared/`），但有 **三处结构性缺失** 让快速迭代变贵，外加 **一批静默 bug** 正在让功能"看起来在跑其实没跑"：
+
+- **缺中间层**：业务逻辑堆在路由/编排函数里（进销存无 service 层、`process_file_core` 280 行线性函数）
+- **缺契约**：前后端靠手写类型，字段已大面积漂移（财务页整页是 0）
+- **缺连接**：模具分析与进销存是两个孤立产品（`STPFile` 没有 `product_id`）
+
+---
+
+## P0 止血：正在静默失效的功能（1–2 周）
+
+这些不是技术债，是**现在就在坏**的东西，先修。
+
+### P0-1 Celery worker 不连 Redis/RustFS，异步任务全坏
+- **现象**：任务进度写进 Celery 私有内存，web 端永远读不到；首次上传 RustFS 直接抛 `RuntimeError("RustFS 未连接")`。
+- **证据**：`redis_task_manager.connect()` / `rustfs_manager.connect()` 只在 FastAPI startup 调用（`entrypoints/moldinsight.py:42,48`），Celery 进程不跑 startup；`processing_service.py` 在 celery 内调 `update_task` 时 `is_connected=False` 走 `_fallback_set`；`rustfs_storage.py:125-126` 未连接直接抛错。`deploy/docker-compose.yml` 的 `moldinsight-celery` 服务块缺 `REDIS_PASSWORD`。
+- **修法**：`celery_tasks.py` 加 `@worker_process_init` 信号，显式 `connect()` redis 与 rustfs；补齐 celery 服务的 `REDIS_PASSWORD`/`SECRET_KEY` 等环境变量，与主应用对齐。
+- **验证**：上传一个 STP，Celery 路径下任务进度能从 web 端 `/api/status/{task_id}` 读到；上传后 RustFS 中能看到对象。
+- **状态**：- [ ]
+
+### P0-2 LLM 设计报告 NameError，静默失效
+- **现象**：`LLM_ENABLED=true` 时设计报告功能直接没有。
+- **证据**：`llm_service.py:339` 用未定义变量 `trimmed`（应为 `features`，`trimmed` 只在 `_build_side_action_prompt` 中定义），外层 `try/except` 吞掉 `NameError` 返回 `None`。
+- **修法**：`trimmed` -> `features`。
+- **验证**：启用 LLM 后设计报告字段非空。
+- **状态**：- [ ]
+
+### P0-3 前端财务页全字段错配
+- **现象**：FinanceTab 整页 0/空；用户管理菜单永不显示（`is_superuser` 后端不返回）；dashboard 成品数恒 0。
+- **证据**：16 处字段名对不上，如 `total_receivable` vs `receivable_total`（`finance_schemas.py:66`）、`order_no` vs `txn_no`（`finance_schemas.py:48`）等；`App.vue:91` 读 `is_superuser` 但 `UserResponse` 无此字段。
+- **修法**：短期按映射手改前端字段；长期靠 P1-3 OpenAPI 契约生成根治。
+- **验证**：财务页卡片与表格显示真实数据；用户管理菜单对管理员可见。
+- **状态**：- [ ]
+
+### P0-4 OCC 线程安全自相矛盾
+- **现象**：偶发崩溃，外层 `max_workers=1` 保护形同虚设。
+- **证据**：`processing_service.py:50-51` 用单线程池序列化 OCC，但 `geometry_analyzer._detect_features`（`geometry_analyzer.py:81`）内部又开 `ThreadPoolExecutor(max_workers=4)` 并行操作 OCC `TopoDS_Shape`。
+- **修法**：特征检测器改串行；或预处理阶段把面特征抽成纯数值，检测器只处理数值不碰 OCC。
+- **验证**：压测大模型反复分析无崩溃。
+- **状态**：- [ ]
+
+### P0-5 `.env` 进了 git 历史，真实密钥泄露
+- **现象**：DB/Redis/SECRET_KEY/LLM key 已进入仓库历史。
+- **证据**：`git ls-files --error-unmatch .env` 命中；`git log -- .env` 有 10+ 次提交；`.env` 内含真实凭据。
+- **修法**：`git rm --cached .env`（停止跟踪，保留本地，后续不再提交）；`SECRET_KEY` 从默认占位符轮换为强随机值。
+- **用户决策（2026-07-13）**：私有仓库，不轮换其他密钥、不重写 git 历史。
+- **验证**：`git status` 显示 `.env` 不再被跟踪（`D .env`）。
+- **状态**：- [x]
+
+### P0-6 铝价路由模块化部署后丢失
+- **现象**：模块化部署后 `/api/aluminum-price/*` 直接 404。
+- **证据**：单体 `main.py:47,155` 挂了 `aluminum_price_router`，但 `moldinsight/api/__init__.py` 的 `_safe_include` 列表不含 `aluminum_price_routes`。
+- **修法**：把 `aluminum_price_routes` 加入 `_safe_include`。
+- **验证**：模块化部署下 `/api/aluminum-price/*` 可访问。
+- **状态**：- [ ]
+
+### P0-7 导出缓存无持久化回退
+- **现象**：多 worker 或重启后导出返回 409。
+- **证据**：`processing_service._export_shapes_cache` 是进程内 dict，`get_export_shapes` 只查内存；`_persist_step_exports` 已写磁盘 manifest 但无回读逻辑。
+- **修法**：`get_export_shapes` 缓存未命中时从磁盘 manifest 回读。
+- **验证**：重启后导出仍可用。
+- **状态**：- [ ]
+
+---
+
+### P0 执行结果（2026-07-13）
+
+- ✅ **P0-1 Celery 连接**：`celery_tasks.py` 在任务内显式 `redis_task_manager.reconnect()` + `rustfs_manager.connect()`（Redis 客户端绑定事件循环，每任务 reconnect；RustFS 同步客户端连一次复用）；`deploy/docker-compose.yml` celery 服务补 `REDIS_PASSWORD`/`RUSTFS_TIMEOUT`
+- ✅ **P0-2 LLM NameError**：`llm_service.py:339` `trimmed` -> `features`
+- ✅ **P0-3 前端字段错配**：FinanceTab 全字段对齐 schema（summary/statement/product-statement/transaction 共 16 处）；`UserResponse` 加 `is_superuser` + 统一 `_build_user_response` 构造（修用户管理菜单不显示）；DashboardTab `product_count`->`finished_product_count`；PurchaseOrdersTab `received_at/paid_at`->`received_date/paid_date`；后端 `FinanceTransactionResponse` 补 `partner_name` 并批量查询客户/供应商名称
+- ✅ **P0-4 OCC 线程安全**：`geometry_analyzer._detect_features` `max_workers` 4->1
+- ✅ **P0-5 .env 泄露**：`git rm --cached .env` 已取消跟踪（后续不再提交）；`SECRET_KEY` 从默认占位符轮换为强随机值（现有登录 token 失效）。用户决策：私有仓库，不轮换其他密钥、不重写 git 历史
+- ✅ **P0-6 铝价路由**：`moldinsight/api/__init__.py` `_safe_include` 加入 `aluminum_price_routes`
+- ℹ️ **P0-7 导出缓存**：经排查**非 bug**——`export_artifacts` 已写 PG+Redis（`processing_service.py:342,361`），导出端点先走 `_select_persisted_files` 从 task_data 读取（`advanced_router.py:436`），重启后正常工作；409 仅在持久化也失败时出现，"请重新分析"提示为正确行为。内存 re-export 缓存的可靠性优化归入 P1-2
+
+**未做验证**：前端未跑 vue-tsc 构建（字段重命名属机械改动，低风险）；后端未跑 pytest（需 DB/Redis 环境）。建议下次在完整环境验证。
+
+---
+
+## P1 结构性地基：让后续迭代不再昂贵（持续）
+
+### P1-1 进销存抽 service 层
+- **现状**：`finance_routes.py` 751 行、`sales_order_routes.py` 777 行，事务编排/库存原子更新/流水写入全耦合在 endpoint；`shared/services/` 仅 auth+redis。
+- **目标**：新建 `inventory/services/`，`PurchaseOrderService.receive()`、`SalesOrderService.issue_materials()`、`FinanceService.settle()`，route 只做校验+组装。
+- **状态**：- [ ]
+
+### P1-2 moldinsight 可插拔注册表 + Stage 流水线
+- **现状**：模具类型硬编码 if-else（`multi_scheme_planner.py:40`）；特征检测器硬编码 6 个（`geometry_analyzer.py:76-99`）；`process_file_core` 280 行。
+- **目标**：`FeatureDetectorRegistry` + `MoldGeneratorRegistry`（`@register` 装饰器）；`process_file_core` 拆成 Stage 链。
+- **解锁**：新增模具类型、IGES/BREP、批量分析。
+- **状态**：- [ ]
+
+### P1-3 前端 OpenAPI 契约生成
+- **现状**：前端 40+ 处 `any`，字段全手写已大面积错配。
+- **目标**：`openapi-typescript` 从 `/openapi.json` 生成 TS 类型替换 `any`；`api.ts` 加 baseURL/拦截器/超时，按域封装 `inventoryApi`/`moldinsightApi`/`authApi`。
+- **状态**：- [ ]
+
+### P1-4 引入 Alembic，废除裸 DDL
+- **现状**：无 `alembic.ini`；`init_db.py` 22 条 `ALTER TABLE ADD COLUMN IF NOT EXISTS`，无版本/无回滚；`migrate_db.py` 是 `drop_all` 破坏性脚本；两应用 startup 并发跑 DDL 争锁。
+- **目标**：`alembic init`，固化版本化迁移，启动只 `upgrade head`；删 `migrate_db.py`。
+- **状态**：- [ ]
+
+### P1-5 统一材料属性源
+- **现状**：材料字典在 4 处重复定义且冲突（PE 收缩率 `material_service` 0.020 vs `aluminum_foam_mold.py:92` 0.025）。
+- **目标**：`MaterialService` 作为唯一源，其他模块查询。
+- **状态**：- [ ]
+
+---
+
+### P1 执行结果（进行中）
+
+- 🚧 **P1-1 进销存抽 service 层**（进行中）：
+  - ✅ 建立 `inventory/services/` 层，抽出 `FinanceService`（`finance_routes` 767→123 行，业务逻辑全下沉；路由仅做参数校验+响应组装）
+  - ✅ 将 `schemas/` 与 `utils.py` 从 `inventory/api/` 移至 `inventory/` 顶层，打破 service↔api 循环导入（schemas 是共享 DTO、utils 是纯函数，本不应嵌在 api 层；这是正确分层）
+  - ✅ import 测试通过：9 finance 路由 + 55 inventory 路由全部正常加载
+  - ⏳ 待办：抽 `sales_order_service` / `purchase_order_service` / `inventory`+`stock_movement` service；清理死代码 `api/utils.py`（待 `git rm`）
+
+---
+
+## P2 功能演进：把两个产品变成一个
+
+### P2-1 打通模具分析 -> 进销存（最高产品价值）
+- **现状**：`STPFile` 无 `product_id`，moldinsight 与 inventory 零数据关联。
+- **目标**：`STPFile` 加 `product_id` 外键（可空），分析完成后一键创建 `Product(finished)` 并回写。
+- **状态**：- [ ]
+
+### P2-2 真 AI 落地，砍掉假 AI
+- **现状**：`ai_mold_assistant.py` 209 行纯 stub 从未被调用；`ai_parting_detector.py` GNN 框架完整但无权重；`llm_service` 是唯一真接 AI（且有 P0-2 bug）。
+- **目标**：聚焦一个能跑通的 AI 能力（LLM 扩到成本估算/工艺对话）；GNN 要么真训权重，要么移除 stub。
+- **状态**：- [ ]
+
+### P2-3 模具成本估算 + 批量分析
+- 依赖 P1-2 完成后才有性价比。
+- **状态**：- [ ]
+
+---
+
+## P3 工程治理（穿插顺手做）
+
+- [ ] `create_app()` 工厂消除两入口重复引导，废弃单体 `main.py`
+- [ ] 删死依赖/死代码：Kafka（零引用）、`templates/` legacy、`ai_mold_assistant` stub、`ProcessingService.__init__` 3 个死实例
+- [ ] `get_db_session` 统一事务边界（commit/rollback），废除路由手动 commit
+- [ ] 连接池治理（3 进程峰值 150 > PG 默认 100），考虑 PgBouncer
+- [ ] 进销存 state 从模块级单例迁回 Pinia，tab 改子路由
+- [ ] 统一 `/health` 响应 schema；SPA fallback 排除 `/api` 前缀避免吞 404
+- [ ] CORS 收敛（`allow_origins=["*"]` + `allow_credentials=True` 不安全）
