The saved checkout simulation recognizes exact uppercase ZELDA20 for twenty dollars and SAVE15 for fifteen. Bars compare nominated reductions at twenty pixels per dollar. Trimming and uppercase conversion happen before lookup. An unrecognized code gives zero nominated valid savings. These are local string branches, not a retailer validation, current offer or evidence either code works. No real cart, subscription or stock lookup occurs. Recognized code alone is insufficient in this source. Eligibility also requires the checked membership box and region active or staged. A nominated twenty realizes only when those local inputs pass. Seventy base then becomes fifty; otherwise it stays seventy. Bars compare those pre-tax amounts at five pixels per dollar. Staged produces a different risk label but the same realized discount. The UI statement about subscription confirmation is a simulation label, not actual account verification. For hypothetical entered eight percent tax, eligible fifty dollar item adds four to total fifty-four. Ineligible seventy adds five sixty to total seventy-five sixty. Bars compare final amounts at five pixels per dollar. The default fixture instead uses zero tax. This is source arithmetic only, not a verified tax rate or actual checkout. Native SAVE15 preset, complete stable receipt and reset preserve recognition, gating and unrounded tax logic without endorsing the saved report or current promotions.
