📝 Walkthrough

Walkthrough

This PR updates test files across the disaggregated module to reflect API changes: imports are adjusted to new module structure, slot allocation expectations shift from raw integers to AuxSlot objects, pool descriptor tests migrate to resource/page abstraction validation, and RankInfo tests simplify with reduced constructor parameters.

Changes

Cohort / File(s)	Summary
Test List Configuration tests/integration/test_lists/test-db/l0_h100.yml	Added seven new test targets to the l0_h100 PyTorch/MPI test list under unittest/disaggregated/region and unittest/disaggregated modules.
Disaggregated Module Tests tests/unittest/disaggregated/region/test_aux.py, tests/unittest/disaggregated/region/test_page.py, tests/unittest/disaggregated/test_rank_info.py	Updated imports to match new module structure; modified slot allocation tests to use AuxSlot objects instead of raw integers; transitioned test_page.py from PoolDescriptor validation to resource/page abstraction serialization roundtrip checks; simplified RankInfo constructor expectations and removed deprecated fields like kv_ptrs, aux_ptrs, and device parameters.
