// Let's verify by trying to "search" for the calculated value if it was indexed?
// The schema defines "word" classification for `avg_bpm`. So "75" should be indexable.
// Using `db_ops` to fetch the atom for "avg_bpm" for a specific user is complex because atoms are UUID based.
// Instead, let's verify via the Native Index search if "75" returns user_123.
// Note: The `avg_bpm` field has "word" classification.
// We need to know the specific partition key structure.
// But for this test, we can trust the `TypedEngine` unit tests for calculation correctness.
// To be thorough, let's add a debug print or a specific check if possible.
// Actually, `transform_execution_test.rs` doesn't verify values, just state.
// Let's use `fold_db.query_executor` if available? No, it's private or behind feature flags often.
// Alternative: We can inspect the `db_ops` directly if we can construct the key.
// Or we can rely on `schema_manager.get_schema` having updated stats? No.
// Let's search for "75" using the public API
// Note: The specific string representation of 75.0 might differ, but our reducer outputs "75" for integers.
