      Currently, all tests using disagg.mode=leader are running only under a single FE variant: Failure Expected (ARMV9) Amazon 2023 Disagg Stress Tests.

      We have observed that for PALite, these tests have been consistently passing. This suggests that the leader-mode tests may now be stable enough to expand across evergreen variants.

      This ticket aims to validate and integrate test/format (disagg.mode=leader) testing across variants similar to follower-mode tests.

      The task includes

      • format-stress-data-validation-test-disagg-leader-palite-*
      • format-stress-test-disagg-leader-palite-*

      Outcome:

      • Confirm leader-mode stability,
      • Integrate tests into normal variants, and
      • Create PR smoke tests for both Leader and Follower modes.
