   This is a test for #34224.

   Also, includes a small test cleanup/refactor.

2. test: Split large init_stress_test into two smaller functions

   This refactor can be reviewed with:
   --color-moved=dimmed-zebra --color-moved-ws=ignore-all-space
   
   This split makes the code easier to read, modify, and understand.

    Nice. Everything works as expected:

    • Test-each-commit CI fails before the fix is applied.
    • Windows CI passes.

    I’ll rebase once the fix is merged.
