A preorder before production.

Founding Members now have a product-led preorder page. A person can choose among six approved V4.3 personal-finish directions and five carry studies, set quantities and see the amount before continuing to payment. Bosphorus blue takes the place of the earlier Deep forest study; Graphite has left the active set.

The finishes belong to the one-piece rear cup. The accessories are separate design studies. Neither is a released production variant: each remains subject to material, RF, load-path, durability and manufacturing evidence.

The page takes payment in full through a secure hosted payment page. Before continuing, it states that the instrument has not been built, gives the September 2028 to January 2029 engineering estimate, names the separate service start and preserves the statutory withdrawal and refund boundaries.

The order is bounded to the active catalogue and one to twelve items. Prices are re-derived on the server rather than trusted from the browser. If a finish changes while the page is open, the order stops before payment and asks the person to reload the current collection; no removed finish is silently replaced with another.

A person must acknowledge the purchase, schedule and privacy boundaries before payment opens. Card details are entered on the secure payment page and are not handled by SA-NT. Founding Circle letters remain an optional choice rather than a condition of ordering.

The contact composition follows the existing waitlist retention and deletion path. The order and payment receipt remain separate commercial records with their own statutory retention basis.
