Open decision
Presale date and customer delivery promise
Working direction
Use 5 October as the working presale target and take payment before US inventory arrives, with a conservative delivery window stated at checkout.
Needed to close
Confirm factory completion, ocean arrival range, US fulfillment handoff, cancellation terms, freight-delay language, and the customer-facing ship window by the 21 September review.
Payment before US inventory is approved. The remaining risk is making a delivery promise before the logistics chain is proven.
