Use ChatGPT Work to turn the dated budget, actuals, ledger detail, forecast, and operating commentary you supply into a variance-review packet: make the calculation path, source cut-off, driver evidence, and unresolved question visible.

The useful object is a review packet with an evidence spine, not an automated finance decision.
