## Experience and arithmetic record

The operator compared August 2026 opex with Budget v3. The question fixed the read-only replica, books-closed-plus-two cutoff, account map, cost-center join, and one-time-reclass exclusion.

Total drivers were contracted services +$420k, cloud +$180k, travel −$90k, mapping miss +$60k, and residual $0: a net +$570k movement. The first narrative blamed hiring; the operator rejected it because the rows showed contractors, not FTE. A vendor-invoice join identified a +$140k reserved-instance true-up component of cloud without counting it again.

The [driver CSV](https://infinisynapse.com/blog-media/fpa-analytics/downloads/driver-table-FPA-OPEX-20260823.csv) publishes six illustrative rows. The [verification script](https://infinisynapse.com/blog-media/fpa-analytics/downloads/verify-FPA-OPEX-20260823.py) confirms the +$570k total and component relationship; it cannot reconstruct private source records.
