newStorage

Returns a fresh, empty RaftStorage instance.

Called once per test — each test drives its own independent storage. The instance must start with term() == 0L, votedFor() == null, leaderForTerm() == null, and entries() == emptyList().

suspend, because opening a durable medium is a suspending act: an adapter over a us.tractat.kuilt.store.DurableStore has to read the medium before it can answer a single one of the four values above, and there is no sound non-suspending way to do that. The alternative — a constructor that assumes an empty medium — is not a shortcut but a data-loss bug: an adapter that skipped the read would answer entries() == emptyList() for a medium holding a log, and its first appendEntries would then write that empty log back over it. DurableStoreConformanceSuite.newStore has been suspend for the same reason since it was written; this hook was not only because the sole implementation at the time had a non-suspending constructor.

Every call site is already inside a runTest { } body, so nothing but the modifier changed.
