  • Update branch and then REBASE to master right after the next b4b-dev merge to master

Description of changes

Similar to #4223 but for g16, g17, g37 grids, updating

  • testlist_clm.xml but left grids unchanged that do not have replacements
  • for those, should we remove them altogether?
  • anything else?
  • RTM, MOSART, mizuroute?

Specific notes

Contributors other than yourself, if any:

CTSM issues resolved or otherwise addressed, if any:
Contributes to #2540 (resolves?)

Testing planned or performed, if any:

  • DO NOT UPDATE BRANCH WHEN Move CTSM tests from t232 to t233 #4223 GETS MERGED BECAUSE THE TWO PRs ARE ORTHOGONAL, AND WE WANT TO CONFIRM THAT THEY EACH COME BACK b4b FOR ALL UNCHANGED TESTS
  • WAIT ./run_sys_tests -s aux_clm -c ctsm5.4.058 --skip-generate with only ccs_config updated to tag 92 (additional submodules are getting updated on master)
    • derecho
    • izumi

Requirements before merge:

  • The code in this PR branch builds with no errors.
  • The code in this PR branch runs with no errors. Briefly describe tested configuration(s):
  • This does not change answers for unchanged tests; tests going from gx grids to t233 run on the new grid and have their names updated, so the test-suites will not compare them to the baseline
  • This PR either (a) does not create a need to update the documentation or (b) includes required documentation updates (see guidelines for contributing documentation). Which?:

I'd call this as something that should go on master, because when compsets change you can't verify that things are b4b. And hence it could hide an accidental non-b4b change on the b4b-dev branch after this was merged.

@wwieder wwieder added testing additions or changes to tests and removed next this should get some attention in the next week or two. Normally each Thursday SE meeting. b4b bit-for-bit labels Oct 1, 2026
@wwieder wwieder added this to the ctsm6.0.0 (code freeze) milestone Oct 1, 2026

Looks like I reintroduced a test that was removed, so correct it.
