+# 量化哨兵（QuantSentinel）通知架构
+
+真源：`QuantRuntimeSettings/platform-config.json` → `notifications.quant_sentinel`
+
+## GCP Secret
+
+| 名称 | 用途 |
+|------|------|
+| `quant-sentinel-telegram-bot-token` | 组织统一哨兵 bot（监控、简报、插件告警） |
+| `crisis-alert-telegram-bot-token` | **已弃用**，保留只作回滚 |
+
+各平台 GCP 项目均应有 sentinel secret 副本：`firstradequant`、`longbridgequant`、`charlesschwabquant`、`interactivebrokersquant`。
+
+## 环境变量（运行时）
+
+| 变量 | 说明 |
+|------|------|
+| `TELEGRAM_TOKEN` | bot token（Cloud Run 由 secret ref 注入；VPS 由 `load_telegram_env.sh`） |
+| `GLOBAL_TELEGRAM_CHAT_ID` | `5992562050` |
+
+别名见 `platform-config.json` → `notifications.quant_sentinel.env_aliases`。
+
+## VPS
+
+```bash
+scripts/load_telegram_env.sh /run/quant-monitor/telegram.env
+systemd/quant-monitor.service.example   # ExecStartPre + EnvironmentFile
+scripts/daily_briefing_pipeline.sh      # → AIAuditBridge --dispatch
+```
+
+## Cloud Run
+
+`STRATEGY_PLUGIN_ALERT_TELEGRAM_BOT_TOKEN_SECRET_NAME=quant-sentinel-telegram-bot-token`  
+`GLOBAL_TELEGRAM_CHAT_ID` 来自 repo variable。
+
+平台执行日报仍用各平台 `TELEGRAM_TOKEN_SECRET_NAME`（独立 bot）。
