Heartbeat 安静确认防泄漏：确保 HEARTBEAT_OK 不被误发到外部频道

问题/场景：心跳轮询应仅做内部 ACK，但 `HEARTBEAT_OK` 偶发外发造成噪音。前置条件：已启用 heartbeat。实施步骤：检查 heartbeat 模板→设置静默策略→做回归压测。关键配置：`showOk:false` + 明确无任务分支。验证：无事项时通道不再出现 HEARTBEAT_OK。风险：规则写错会吞掉真实告警。

Prerequisites

Heartbeat polling is active and channel delivery behavior is observable in logs/history.
You can edit HEARTBEAT.md and gateway heartbeat settings safely.

Steps

Review heartbeat prompt text to ensure the no-work branch returns only HEARTBEAT_OK (no extra prose).
Keep HEARTBEAT.md empty/comment-only when no periodic task is needed, reducing accidental outbound content.
Run multiple heartbeat cycles and inspect channel history for any leaked HEARTBEAT_OK tokens.
If leakage persists, pin version/patch and track upstream fix issue until merged.

Commands

openclaw status

openclaw gateway status

Verify

Across several heartbeat runs with no pending tasks, no HEARTBEAT_OK text appears in user-facing channels.

Caveats

If your workflow relies on visible heartbeat confirmations, removing channel ACKs may reduce operator confidence.
Final behavior depends on deployed gateway build and channel plugin implementation（需验证）.
