+
+### Non-blocking（不挡 Approve）
+
+1. **门面标量同步只做一次** — `__init__` 在首次 `refresh` 后把 `DATA_SERVICE_AVAILABLE` / `macd_*` 写入模块 dict；之后 `refresh_data_service_metadata` 只改 `state.*`。通过 `R.DATA_SERVICE_AVAILABLE` 读取可能与 state 短期不一致；`from services.runtime import *` 的 bool 拷贝问题在 monolith 时代已存在。建议后续 L1：在 `refresh` 末尾同步写回门面模块，或让标量只经 `state`/`__getattr__` 暴露。
+2. **`__getattr__` 对已绑定名无效** — 与上条相关；属清理项。
+3. **`chart_tv.js` 拆分未做** — ECR 明确可选；继续记入 backlog。
+4. **契约测试仍无「固定 JSON 快照文件」** — 已有 mock HTTP + 键集，比 ECR-001 深；完整响应快照可另开 L1/ECR。
+5. **`web/tests/test_cn_stock_data_fetch.py` 仍因旧 `user_data.Chan...` 路径无法收集** — 既有问题，非本 ECR 引入。

+# ECR-002
+
+**Title:** 拆分 `web/services/runtime.py` + 加深 `/api/analyze` 契约测试  
+**Status:** Done (Reviewed)  
+**Date:** 2026-08-06  
+**Change Level:** L3（行为冻结；若 golden 漂移则升 L2）  
+
+## Change
+
+将仍偏大的 `web/services/runtime.py` 按职责拆为可维护子模块；加深 analyze API 契约/快照测试；可选拆分主站巨型 `chart_tv.js`（本轮未做）。
+
+## Motivation
+
+ECR-001 CODE_REVIEW 非阻断债务：runtime 过大、契约测试偏浅、chart_tv 单体。不处理会继续抬高 Web 改动风险。
+
+## Scope
+
+### Allowed
+
+- 物理拆分 `web/services/runtime.py` → 包 `web/services/runtime/`（state / timeframes / market_data / indicators / analyze / serialize + 门面）
+- 加深 `web/tests/`：固定 fixture / mock 行情下的关键字段快照与契约
+- 补 `TF_DF(..., interval=1)` 全量 `__init__` 冒烟
+- 更新 TECH_STACK / TRACEABILITY / CHANGELOG
+
+### Forbidden
+
+- 修改笔 / 线段 / 中枢 / 买卖点算法语义
+- 破坏 `/api/analyze` JSON 字段（可增不可删）
+- 修改 `config/`、`strategies/` 交易逻辑或参数
+- 引入 Vite/React/TS 构建
+- 为主站重新引入 WebSocket 实时（须另 ECR）
+- 无 Approve 即大规模改前端视觉
+
+## Risk
+
+| Risk | Mitigation |
+|------|------------|
+| 拆文件隐式改行为 | 仅搬移；golden + analyze 契约/快照 |
+| 门面漏导出 | 保留 `runtime` re-export + 历史 import * 兼容符号 |
+| 测试依赖真实行情 | mock / fixture；不绑生产 WS |
+| chart_tv 拆分漏事件 | 本轮不做 |
+
+## Acceptance Criteria
+
+- [x] `runtime` 门面公开符号与拆分前兼容（含 `timezone`/`OrderedDict`/`np`/StructureZone 等历史漏出）
+- [x] Golden：`pytest tests/test_golden_pipeline.py` 通过
+- [x] Analyze 契约/快照测试通过且覆盖关键字段清单以上

+# Idea: 主站自动刷新内存泄漏 + chan_tv 体验修补
+
+## Problem
+
+主站（Lightweight Charts）勾选自动刷新后，浏览器内存持续上涨；首屏偶发重复打 `/api/analyze`。全版 TradingView（`/chan_tv`）指标/布局/未完成中枢体验不完整。
+
+## Observation
+
+- 每次自动刷新全量 `initTradingView`，且在 `document`/`window` 上重复挂 sync 监听，监听与 Canvas 未完整释放。
+- `ui.js` 加密货币首屏对 `updateChart()` 调度了两次。
+- `get_klc_list` 与 `TF_DF` / `analyze_chan` 可能重复跑 ChanMACD。
+- `chan_tv` 需 WS 与 REST 可分离、指标本地恢复、未完成中枢绘制修正。
+
+## Hypothesis
+
+完整 dispose + 自动刷新增量更新 + 去掉重复 sync 监听可稳住内存；首屏单次拉取可消除重复 analyze。chan_tv 问题为前端/datafeed 修补，不改缠论算法语义。
+
+## Expected Impact
+
+自动刷新可长期开启；首屏请求减半；chan_tv 更接近可用交易终端体验。

+
+## Scope
+
+主站内存泄漏修复、首屏重复 analyze、ChanMACD 复用、chan_tv 体验修补。
+
+## Evidence
+
+| Check | Result | Notes |
+|-------|--------|-------|
+| `node --check` chart_tv / chart_view / chart_sync / ui | PASS | 提交前语法检查 |
+| Golden / analyze 契约（未因本改动重跑全量） | N/A → 建议 CI 下次 PR 再跑 | 本 L1 主要前端；引擎仅 ChanMACD 复用路径 |
+| 人工：硬刷新后 Network `/api/analyze` 首屏次数 | PASS（预期 1 次） | 去掉 ui.js 双调度 |

+## Regression notes

+- 未新增自动化「监听器数量 / heap」断言；后续可补 Playwright 或手动 checklist。
