• One adopter command can be one provider transaction. AtomicBatchStore extends Store for providers that can apply an ordered slice of AtomicCommit { decision, expect } values or none of them. Expectations see earlier entries in the same transaction, while a conflict or backend failure rolls every instance and event back. MemoryStore, SqliteStore and PostgresStore implement the stronger contract; the shared suite is also run against a deliberately prefix-committing provider so the rollback case is known to fail. R-112.
