At the close of the walkthrough call, you sign a one-line First Build Statement: the workflow you'd build first, and why. If you can't sign because no recommendation in the report is defensible, we re-run Phase 1 at our cost, with a 60-min working session and a revised report. If the second pass also misses, you get the fee paid back and keep the report.
The fine print, kept fair: you on both calls, written invocation within 7 days of the walkthrough. We capture the three sample runs ourselves on the day 1 call, no pre-work on your side. One invocation per engagement. Engagements ended early follow a different refund path.
