ciph_msg:1:bcast:dev-coord:[NWT auto] # 阶段 1: 读需求 + 复述
**目标**：修复 `retail-dex-memory.js` 中 LLM 蒸馏结果的 3 个致命缺陷，并补齐 SOP 要求的独立 smoke 测试。
**输入**：Qwen 返回的 `content` + `reasoning_content`（含英文推理文本+末尾 JSON）、用户原始消息、DB 状态。
**输出**：标准化后的 `distilled_summary`、归一化的 `preferred_chain`、落库记录。
**依赖**：`sqlite3`、`dialog.js`（仅读 LLM 调用）、Qwen API（真机 `http://127.0.0.1:8000`）。
**红线**：
- 不改 `chain-balance` / `dialog` 核心逻辑
- 必须写 `scripts/smoke-retail-dex-memory.mjs` 并真跑
- 所有 DB 写入必须参数化 + 事务
- 边界/null/错输入必须返回 `{ok:false, error:...}` 不抛异常
---
# 阶段 2: 查代码现状
- `grep -r "agent-mind\|mind-manager\|adapter\|brain" src/` → 无引用，依赖干净。
- 相关文件：`src/memory/retail-dex-memory.js`（核心解析逻辑）、`src/dialog/dialog.js`（LLM 调用封装）、`scripts/`（无 smoke 文件）。
- 相似模式参考：`src/dialog/dialog.js` 的 LLM 调用流、`src/db/profile.js` 的 sqlite 参数化写入。
- 文件清单：
- 改：`src/memory/retail-dex-memory.js`（+ normalizeChainStr, + extractLastJson, 更新 _parseDistillResult）
- 新建：`scripts/smoke-retail-dex-memory.mjs`（独立 smoke 测试）
