Legacy: final % = variant % + customer % − the largest active promotion on the product, its category or its brand; rial charge 0. The apps sent the variant's own % only, so the new app undercharged by the customer's percent (usually 3) and ignored promotions, and the server trusted whatever the app sent. - pricing/wage-formula.ts: one formula, legacy by default, with coefficients, promotion pick, constant, floor/cap and rounding so the admin screen can change it; validated - an app order is priced by it; the app's wage, discount and rial charge are ignored; an operator's manual numbers are kept - POST customer/me/wage-quote; both apps show that figure - admin/pricing/wage-formula (config.wage): read, preview, approve with the sample it was checked on, last 20 versions kept; the setting is kept off the generic const routes Owner approval: 2026-10-08.

// Adapts our actual ProductSummary (apps/user-app/src/api/client.ts) into the
|
||
// same output shape legacy's Mixins/product/index.ts `useProduct()` produced.
|
||
// The legacy card components it was originally shaped for (ProductHorizontal/
|
||
// ProductVertical/ProductVerticalFull) are gone, replaced by the redesigned
|
||
// components/product/ProductCard.vue, components/home/ShowcaseCard.vue and
|
||
// components/product/CartItem.vue — all of which consume this same contract.
|
||
//
|
||
// Honest gaps vs. legacy (no backend equivalent exists yet — apps/api was not
|
||
// touched to add these):
|
||
// - promotions/discounts: legacy matched a customer's order against admin
|
||
// promotion + ignore-list rules (getCandidPromotions/getPromotion). No such
|
||
// data exists in the new API, so `hasDiscountWage` is always null here —
|
||
// the discount badge and "before/after" price never render, which is
|
||
// correct given there is genuinely nothing to show, not a bug.
|
||
// - `wage` now comes from the server (wageQuoteStore), which adds the
|
||
// customer's own percent and the promotion exactly as legacy did.
|
||
// - `is_exist` (stock) and `has_warranty`: no such fields exist on our
|
||
// ProductVariant model yet — always true / false respectively.
