Soul findings on #135: the single-file merge matched on schema id where push matches on type, so a record under another schema id was refused as a retype; redb refused a batch repeating a key; the owned redb merge and a stale revert were unpinned; write_all_unlocked kept a dangling-link branch no caller can reach.

push_all applies the given entries onto the store as it is under its lock or transaction instead of replacing it, so a cache with a stale image cannot drop a record another writer added. put_prepared_batch sends only its staged records.
