TripSense 行知 · 周边出行顾问：首版

零依赖 Node 服务，三步流程（选出发地 → 分析候选 → 生成方案 + 路线图 + 住宿参考）。 - 候选发现：高德 place/text 类型词跨城检索 + 内置景区/城市/小众库 + Photon 兜底 - 区县级「排除同城」判定（adname），过滤发生在轮转取样之前 - 路线图画的是 AI 方案里实际安排的每个地点，按正文顺序编号 + 虚线动线 + 真实高德底图 - 住宿：RollingGo 只读 CLI 取实时报价，无价格源时如实标注不编造 - 服务端内存缓存（指纹 + TTL + LRU），数据源层与 HTTP 层分别缓存 - 上下文瘦身：逐日天气只给 rank1，紧凑 JSON，实测约 1335 token
