Objective: test/checkpoint provides essential coverage to ensure that disagg is foundationally tested. Running test/checkpoint consistently across multiple variants helps validate disagg behaviour under different configs and environments, increasing confidence in its correctness and stability.

This ticket tracks the work to add disagg support for test/checkpoint in Evergreen.

Scope / Goals

• Evaluate existing test/checkpoint tasks in Evergreen
• Determine which tasks are good candidates for disagg
• Create disagg tasks for testing test/checkpoint where appropriate
• Integrate to several build variants
