I'm getting varying results here. Generates three anomalies locally, but only one here on GitHub. Not sure why, but it shouldn't matter for testing the code path of getting the anomalies saved into the database.

Let's investigate on behalf of a subsequent iteration.

There is a test failure for tests.test_tracking.TestSqlAlchemyStore testMethod=test_log_inputs_with_duplicates_in_single_request that also appears after a retry. Sounds unrelated to the example change? Do you have an idea where that comes from, @amotl?

test_log_inputs_with_duplicates_in_single_request is flaky, see GH-11. It succeeded when retrying another time.
