Start with the reported HTTP API failure and the libsql_server::hrana::batch::catch_batch_error entry point, then reproduce the migration error involving BEGIN, COMMIT, or SAVEPOINT statements. Done requires identifying the cause of the 500 response and confirming the affected migration path behaves correctly.
