"""上游信号只读快照 (2026-08-12: 只展示、不进任何下单/决策逻辑)。

把三系统盘中信号取最近若干条给页面看:
  · 决策系统(bionic) 买卖广播 + 风控卖出动作          —— 208 db2 intraday_signals / db3 llm_sell_actions
  · 盘中择时层(intraday_timing) BUY 入场 + 双向风控告警 —— 208 db2 intraday_signals / intraday_alerts
  · mtf 资金异动 + 实况分关注/回避榜                    —— 208 db2 stream:metrics / 214 db0 mr:board

**严格只读**: 一律 XREVRANGE / ZREVRANGE 取最近, 不建消费组、不 ACK、不写 —— 碰不到上游的消费与
投递, 也不和 PMS 现有信号消化(signal_service 的消费组)抢消息。连不通的源单独降级 (ok=False + error),
不影响其余与整页。取数带进程内缓存 (默认 8s), 不高频打上游。
`intraday_signals` 一条流两家都写、格式不同: 按 producer_id / entry_score 字段特征分成
「决策系统」与「择时层」两类展示。
