+- 环比数据：`collect_ai_analysis` 每次运行先采集当日盘面快照（指数+涨跌统计 JSON）写入 `daily_market_stats` 表（UNIQUE trade_date，upsert），再读上一交易日快照格式化为 prompt 中的"环比数据段"；首跑无昨日数据时 AI 须如实标注"暂无昨日基准"
+- 连板梯队：`get_market_dashboard` 返回 `limitLadder` 字段（完整版，2连板以上全量+首板前8），涨停原因/封单金额来自涨停池按 thscode 匹配；看板 events 里的天梯仍只取每层前2（保持 UI 精简），两处用途不同不要合并
+- tokens 口径：`ai_reports.tokens_used` 只记"当次生成"消耗（约7万/份）；同日重新生成走 UPSERT，`generation_count` 自增、`updated_at` 刷新、`created_at` 保留首次生成时间；表有 UNIQUE(trade_date, report_type)，禁止改回 INSERT OR REPLACE 之外还要注意别用 lastrowid（UPSERT 更新时不可靠，须回查 id）

+- 截断续写：报告长导致 finish_reason=length 时，拼接已有内容并向 messages 追加"继续"指令让模型续写（最多3次），truncated 仅在续写后仍截断时为 true；call_llm 读超时 300s（续写携带全部上下文）
+- 快照入库防护：_capture_market_snapshot 校验 indices 非空且涨跌统计不全 0，fuyao 失败时跳过入库，防止空快照污染环比
+- 调试注意：独立脚本跑 backend 代码必须显式 `load_dotenv("/path/to/repo/.env")`——fuyao_apikey 在仓库根目录 .env（uvicorn 靠 --env-file 参数加载），backend/.env 只有 MX keys；且 stdin 脚本里 load_dotenv() 无参调用会因 frame 断言报错，须显式传路径

+- 工具结果必须瘦身：`get_active_core_stocks` 只保留出现次数前25只+题材前5（全量145KB会撑爆上下文）；get_market_dashboard 全量约13KB可接受
