  executive_summary: >
    Synthetic Commerce Co. is evaluating a move from ADB-S to ADB-D for a
    fraud analytics workload where predictable performance, read-path cleanup,
    and storage economics are more important than a pure near-term cost takeout.
  drivers:
    primary: "Stabilize fraud analytics performance while keeping the business case auditable."
    urgency: "Validate capacity, TCO crossover, and migration bridge assumptions before procurement."
