@owenlittlejohns, @ank1m,

I've revised the Harmony regression test notebook, and I thiiiink it's good. The tests for UAT are passing.

The tests in PROD don't yet produce the same output as the tests in UAT, however, despite using matching granules. I believe that is because of the difference in versions currently deployed in the environments:

PROD: l2ss-2.11.0, batchee-1.1.0, stitchee-1.2.1, concise-0.9.0
UAT: l2ss-2.12.0rc14, batchee-1.2.0, stitchee-1.5.0, concise-0.10.0rc4

The latest versions in UAT have important changes/features—such as stitchee applying a dataset sorting, which enables consistent results—that the PROD versions don't yet have. Once the latest versions are deployed to PROD, I'd expect the tests to pass for PROD too.
