SQLite in-memory engine with StaticPool: the missing dialect-fidelity constraint for SQLAlchemy tests

An integration suite for SQLAlchemy can be configured around an in-memory SQLite engine created with create_engine('sqlite://') and a StaticPool , so a single connection keeps the schema visible across sessions. A SAVEPOINT-based fixture can then bind a Session to an outer transaction and roll back each test. This arrangement needs no production credentials
