Jira issue: CRDB-68508

Start with sql.TestTruncateTable in multitenant_admin_function_test.go, especially the condition reported at lines 451 and 488. Review the linked TeamCity logs and artifacts to compare the expected descriptor path with the observed result on the ARM64 run. Done means the test completes without the 45-second condition failure and verifies the expected truncate result.
