## Message

```
persist: a future history stamp no longer defeats the 15-minute gate (#142)

After the clock steps back (dual-boot RTC in local time, NTP correction,
a state dir copied from a skewed machine) the future copy sorts last, so
the gate saw it as not recent and every 2s flush made a new copy,
pruning the older 15-minute history within minutes. Judge recency by the
newest copy that is not in the future.
