+## 2026-05-17 低负载生产值守调度与 Webhook 通知入口
+### 本轮完成项
+- 已把生产值守调度改为适合资源紧张服务器的低负载模式：
+  - 计划任务：`AIContractProductionWatchdog`
+  - 执行时间：每天 `02:00`
+  - 通知策略：`WarnOrFail`，正常 PASS 不通知，只有 WARN/FAIL 才通知。
+  - 日常巡检只做轻量生产 ops check；容量治理 dry-run 不放进每日任务，保留给维护窗口单独执行。
+  - 日常任务跳过本机开发工作区 clean 检查，避免开发机未提交前端改动造成假告警。
+- 已增强 `scripts/run-production-watchdog-scheduler.ps1`：
+  - 默认时间从 `07:30` 调整为 `02:00`。
+  - 新增 `WebhookKind=auto`，可按 URL 自动识别企业微信、钉钉或通用 Webhook。
+  - 新增钉钉 markdown payload。
+  - 注册任务不再硬编码 `-RequireCleanWorktree` 和 `-FailOnWarn`。
+  - 新增 `-SkipWorktreeCheck`、`-SkipCapacityGovernance` 透传能力。
+- 已增强相关子脚本：
+  - `scripts/run-production-watchdog.ps1`
+  - `scripts/run-production-ops-check.ps1`
+  - `scripts/run-capacity-governance.ps1`
+  - 支持日常巡检场景跳过本机工作区噪声。
+
+### 本轮验证
+- 企业微信 payload dry-run：
+  - `PHASE7_WATCHDOG_SCHEDULER_PASS`
+  - 产物：`project-docs/qa-artifacts/phase7.5-watchdog-scheduler/2026-05-17T18-34-32-390/watchdog-notification-payload.json`
+- 钉钉 payload dry-run：
+  - `PHASE7_WATCHDOG_SCHEDULER_PASS`
+  - 产物：`project-docs/qa-artifacts/phase7.5-watchdog-scheduler/2026-05-17T18-34-32-389/watchdog-notification-payload.json`
+- 计划任务 dry-run：
+  - `PHASE7_WATCHDOG_SCHEDULER_PASS`
+  - 产物：`project-docs/qa-artifacts/phase7.5-watchdog-scheduler/2026-05-17T18-34-32-406/watchdog-scheduler-summary.md`
+- 真实注册计划任务：
+  - `PHASE7_WATCHDOG_SCHEDULER_PASS`
+  - 产物：`project-docs/qa-artifacts/phase7.5-watchdog-scheduler/2026-05-17T18-35-03-112/watchdog-scheduler-summary.md`
+  - Windows 任务下一次执行时间：`2026-05-18 02:00:00`
+- 同配置手动轻量巡检：
+  - `PHASE7_WATCHDOG_SCHEDULER_PASS`
+  - 产物：`project-docs/qa-artifacts/phase7.5-watchdog-scheduler/2026-05-17T18-35-27-004/watchdog-scheduler-summary.md`
+  - 子巡检：production ops check PASS，capacity governance SKIP，working tree SKIP。
+
+### 当前状态
+- 每日凌晨 2 点低负载生产巡检已经启用。
+- 计划任务命令只引用 `AI_CONTRACT_WATCHDOG_WEBHOOK_URL`，不把真实 Webhook URL 写进 Git、脚本或任务命令。
+- 当前没有真实 Webhook URL 时，巡检仍会正常产出本地证据；配置 URL 后，企业微信或钉钉会在 WARN/FAIL 时收到通知。
+
+### 仍需配合项
+- 需要提供一个真实 Webhook URL：
+  - 企业微信机器人 URL，或
+  - 钉钉机器人 URL，或
+  - 其他能接收 JSON POST 的通用 Webhook。
+- URL 应只配置到运行环境变量 `AI_CONTRACT_WATCHDOG_WEBHOOK_URL`，不能写入仓库文档或代码。
+- 如果使用钉钉且机器人开启“关键词”安全策略，关键词建议包含 `AI Contract Platform`，否则钉钉会拒收消息。
+
+### 阻塞项
+- 本轮无 required 阻塞项。
+- 真实外部告警到人仍等待 Webhook URL；在 URL 提供前，系统已完成本地证据闭环和 02:00 低负载巡检调度。
+
