+# Phase 3a Web API 完整化 Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development. Steps use checkbox (`- [ ]`) syntax.
+
+**Goal:** 把 Phase 2 的同步轻量 API 升级为异步、可登录、带进度推送、因子报告完整的后端。
+
+**Architecture:** FastAPI + ProcessPoolExecutor（spawn context）做异步回测，JWT 单用户鉴权，WS 连接池推阶段进度，analyzer 补完整 alphalens tears pipeline。
+
+**Tech Stack:** FastAPI + uvicorn、concurrent.futures.ProcessPoolExecutor、PyJWT、websockets（FastAPI TestClient）、alphalens（容器）。
+
+## Global Constraints
+
+- **vnpy 零改造**：源码 `vnpy_v4.4.0/`，`sys.path.insert(0, _VNPY_SRC)`（参照 sanguo_data/datareader.py:6-9）
+- **Python 3.14 本地 / 3.10 容器**；本地无 polars/alphalens/vnpy_ctastrategy → lazy import + mock 测试（参照 Phase 2 模式）
+- **Phase 2 接口复用**：`result_store`（save_result/load_result/BacktestResult）、`cta_engine.run_cta_backtest`、`cta_optimizer.run_cta_optimization`、`registry/library`、`runner.Orchestrator`
+- **ProcessPoolExecutor 用 spawn context**（vnpy/alpha 已用 spawn，兼容）
+- **WS 简单连接池**（dict[task_id, set[WebSocket]]），不做重连/心跳（YAGNI）
+- **JWT 单用户**：用户名/密码 hash/jwt_secret 配 `config/backtest.yaml`
+- **测试策略**：本地 Python 3.14 跑 mock 测试 + 容器 Python 3.10 跑真实依赖测试（polars/alphalens）+ 端到端冒烟
+- **覆盖率 ≥ 80%**，TDD，每 task commit
+- **不引 Qlib/Celery**，不做组合回测/多用户/Vue 前端（留后续 phase）

+## Self-Review
+
+**1. Spec coverage**：异步 pool(T3) + runner async(T4) + WS 阶段(T2/T5) + JWT 单用户(T1/T5) + optimize/factor 路由(T5) + alpha tears 完整化(T6/T7) = design §0 五项全覆盖 ✅
+**2. Placeholder**：tears pipeline 的 forward returns 细节（T7）依赖 alphalens API，标注执行时细化；其余代码完整。
+**3. Type consistency**：`Orchestrator.async submit_*`（T4）在 routes（T5）调用一致；`manager.broadcast`（T2）在 app on_stage（T5）调用一致；`compute_factors`（T6）在 analyzer（T7）调用一致 ✅
