How to review

@r-aneeque

• Check that the input data files now contain the correct data for the DIGSY-{BEST,WORST}-{C,S} scenarios. I tried to consolidate the many commits inserting/changing/reverting values in these files, for instance commits that used scenario labels like "SSP(2024).2" and "DIGSY-BEST" before the "DIGSY-BEST-S" etc. labels were added.
• Confirm that we can delete the branch for Run DIGSY/transport scenarios for 2025-W36 #415 and https://github.com/iiasa/message-ix-models/commits/transport/2025-w20-digsy/ or, if there are data changes there that need to be preserved, give a specific list of which values in which data flows.

The tests for Python 3.9 and upstream version 3.8.0 are not passing, is that intentional?

Ah, no—I seem to have used some features that were not advertised as being added in 3.10 or later. Will adjust.

@glatterf42 I think I ran into python/cpython#136672 —this affected my local (Ubuntu) copy of the 3.13.3 docs, but the updated 3.13.7 version on docs.python.org has the notification. I've adjusted the code to work with earlier Pythons, so tests are now passing.

[glatterf42]

Thanks, lgtm since tests are all passing :)
