> `tracePersist(Buffer)` evaluates `buffer.toDebugString(INCLUDE_HASH)` as a
> call argument, outside the `isTraceEnabled` guard, so every persisted
> in-flight buffer pays a full copy + hash + allocation even when TRACE is off
> [1]. Fix: guard the conversion, like the other `tracePersist`/`traceRecover`
> overloads already do [2].
