+# F-176 — Design
+
+Use `p.name`, `p.state='active'`, `v.sku/ean`, `inventory_stock.available`, `pricing_variant_prices.net_unit_amount_cents`, and categories linked by `product_id`. Search EAN with `ILIKE` so scanner input and partial manual barcode searches both work. Keep all input parameterized.

+# POS product search
+
+The POS search field accepts product names, SKU, full EAN and partial EAN text. Lookup failures now display an explicit API error instead of the misleading “Sin resultados”.

+# F-176 — Implementer
+
+## Cause
+POS lookup SQL was written for an obsolete schema and referenced nonexistent columns: `v.name`, `v.active`, `p.active`, `inventory_stock.quantity`, `pricing_variant_prices.price_cents`, plus category links by variant. PostgreSQL returned 500; the UI swallowed it and rendered “Sin resultados”.
+
+## Changes
+- Search uses product name/state and current variant SKU/EAN.
+- Inventory uses summed `available`, scoped to the active store.
+- Price uses offer or current net amount.
+- Category lookup uses `catalog_product_categories.product_id`.
+- Manual partial EAN search uses parameterized `ILIKE`; exact EAN/SKU endpoints were repaired too.
+- UI now exposes API search errors rather than reporting false empty results.
+
+## Evidence
+- Project TypeScript PASS.
+- POS Next build PASS.
+- `git diff --check` PASS.
+- Authenticated runtime search `q=590123412345`: HTTP 200, 12 existing products.
+- Exact EAN `59012341234501`: HTTP 200, Almendras Crudas Ecologicas, stock 25, price 895.

+POS search currently executes stale SQL against nonexistent variant fields (`v.name`, `v.active`, `p.active`, `s.quantity`, `pp.price_cents`, category-by-variant), then hides HTTP 500 as an empty result. Align search/EAN/SKU queries with current catalog, pricing, inventory and category schemas. Barcode text must support exact and partial EAN lookup.
