MESSAGEix-Transport itself:

• Pick up data changes to be preserved from the "working branch" CircEUlar runs for 2025-W48 #462, so it can be archive/the PR can be closed.
  • CircEUlar runs for 2025-W48 #462 (comment), which is the same as CircEUlar runs for 2026-W06 #474 (comment)

• Reporting:
  • Select out meaningless entries appearing in IAMC tables for final energy, energy services.
  • Adjust IAMC ‘variable’ names for transport reporting #498
• iiasa/message_data#608

Materials-Transport integration / CircEUlar project

• Expand transport reporting with material inflows, outflows per technology and technology groups.
• elasticity-f file does not pick DIGSY scenario values #526

Housekeeping/other items

• Simplify definition and use of pytest marks across the test suite.

• Add a new pytest mark "ci_linux_only" and apply it to some of the slowest tests.
  This mark skips these tests on Windows and macOS, which are typically the slowest jobs. Compare jobs A and B:

  • ubuntu-latest A: 18–30 minutes. B: 21–30 minutes.
  • macos-latest A: 27–109 minutes. B: 15–55 minutes.
  • windows-latest A: 23–45 minutes. B: 13–25 minutes.

  The marked tests include 18 of the 20 slowest:
