"""Test 115.2: Accounting storage rollup arithmetic correctness.
Seeds a synthetic cluster with deterministic rows directly in MySQL, triggers
sacctmgr rollup for an explicit time window, then verifies rollup output
through the documented sreport interface.
Data is pulled from the rollup table with the longest interval that can
satisfy the requested report period (sreport.1, DESCRIPTION), so the hour,
day and month rows are each checked by asking for the matching window.
Per-TRES values come from a single -T per report, which keeps one TRES per
row and needs no TresName column.
Skipped outside auto-config mode; the fixtures seed rows through the mysql
helper that conftest only provides there.
Run this only against a throwaway accounting DB. sacctmgr rollup takes no
cluster argument, so every rollup here recomputes and overwrites usage rows
for every cluster in the DB over the window it covers -- and a window whose
source jobs were already purged recomputes to empty.
